Dear Miss Nutting:- We take great pleasure in inscribing this little book to you in appreciation of the splendid work you are doing in maintaining a high standard for the nursing profession. Very sincerely, JULIUS FRIEDENWALD, JOHN RUH RAH. PREFACE TO THE FIFTH EDITION. The continued cordial reception of this little book has made it a pleasure to add to it the changes neces- sary to bring it up to date. The subject of diet is receiving more and more attention of late, and the studies in metabolism both in health and disease are leading to a new conception of the subject. While we have made a large number of changes in this new edi- tion, we have not added anything which is not pretty generally accepted, and will let the test of a few years of experience show whether many of the new ideas are valid before adding them to the already overburdened curriculum of the nurse in training. We trust that this little volume may be of service not only to the nurse but to the layman in search of information on the subject of dietetics. For a more extended treatment of any of the subjects the reader is referred to our larger book, "Diet in Health and Disease." Baltimore, Md. March, 1924. 3 PREFACE. This little book has been prepared to meet a need in the training-school and as a handbook for nurses and laymen who are interested in the subject of feeding the sick. At present the nurse must rely upon a knowledge of dietetics gleaned either from her text-book on invalid cookery or from one of the larger reference works upon the subject. The former contains too little, and the latter is much too large and too technical to be of great service to the busy nurse. The aim of this book is to give the essentials of dietetics. The physiology of digestion has been briefly reviewed. The various classes of foods and the part they play in nutrition have been considered. The sub- jects of infant feeding and the feeding of the sick have been fully discussed, and a brief outline has been given of the principles involved in the nourishment of patients suffering with the various diseases in which diet plays an important part in the management. Rectal alimenta- tion and the feeding of operative cases have been fully described. Diet lists and instructions have been added which should enable the nurse to comprehend and to intelligently carry out the orders of the physician. A 5 6 PREFACE. large number of recipes for the invalid's dietary have been added. Should the reader desire further information on any of the subjects mentioned or concerning other dietetic topics he should consult our larger work, " Diet in Health and Disease." CONTENTS.

Food is the matter taken into the body to supply heat and energy, to build up the body, and repair tissue waste. Every movement we make uses up a certain amount of energy; this and all the heat that is dissipated from our bodies must be supplied by the food. The energy in the food is present in a resting or latent form in the power which binds atoms together in molecules and the molecules together into a mass. When the complex food forms are broken up into simpler compounds this energy is set free and is used by the body as energy or con- verted into heat. The excess is stored up in the body, usually as fat, in the subcutaneous tissue, or as glycogen in the liver and muscles. This energy is liberated by a series of changes which may be compared to the burning of coal or wood in a furnace, the difference being that the chemic changes are much more complicated, and the body is a much more perfect furnace than any which man has devised, as it can utilize a greater proportion of energy with much less waste. The structures of the body-bones, muscles, nerves, etc.-are built up after birth by material which is taken into the body as food. The wear and tear of the body 11 12 DIETETICS FOR NURSES. necessitates continual repair of these tissues, and the material used for this also comes from the food. Food, as it is taken into the body, differs very much in composition from the material that can be utilized by the tissues in growth and the repair of waste. The proc- esses which prepare it for the use of the body are spoken of as digestion. The chemic elements contained in the body are also found in the food. Some fifteen elements are present in the body, the principal ones being oxygen, hydrogen, carbon, nitrogen, calcium, phosphorus, and sulphur. The compound substances which these make are classi- fied under the headings protein, fats, carbohydrates, mineral matter or salts, vitamins, and water. Water.-Water enters into the composition of every tissue in the body and forms over 60 per cent, of the entire body-weight. It is not burnt up, however, and so does not supply any energy. Salts.-These form about 6 per cent, of the weight of an adult man. They are present in the bones, teeth, and other tissues. The principal salts of the body are calcium phosphate and the various compounds of potas- sium, sodium, magnesium, and iron. The mineral salts are very necessary to life and health. Protein.-Under this heading are included most of the food-stuffs containing the element nitrogen. Protein is found in both animal and vegetable food, familiar ex- amples of it being the lean and gristle of meat, the white of egg, the gluten of wheat, and the curd of milk. The word " proteid " is used by some writers to describe these. Various writers classify the proteins into albumins, as the white of egg; globulins; glutelins; albuminoids, etc. These classifications are frequently changed and need not concern us here. CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 13 The Amino-acids.-Protein is a very complex sub- stance and exceedingly difficult to analyze, but modern chemists have shown that it is built up of simpler sub- stances known as the amino-acids. In the neighborhood of twenty of these have been described, and the more important are called glycocoll, valin, leucin, tyrosin, cystin, and tryptophane. In the process of digestion the proteins are split into these simpler compounds, and it is thought that these are absorbed directly into the blood and circulate in it, and are used to build up the tissues and repair the wear and tear very much like various building materials being carried to buildings, where each need is supplied for construction and also for repair. Some amino-acids contain essential things which others lack. For perfect nutrition and growth it is necessary to have proteins which are suitable, and an animal may be supplied with a superabundance of certain proteins and then not thrive because they do not contain the correct building material. Sometimes the amino- acids are compared to the alphabet and the various tissues to words. One readily sees how it is impossible to spell certain words if any of the letters are absent. It also makes plain how there can be so many different kinds of proteins with specific reactions, as is shown by modern serologic work, as with eighteen letters millions of different combinations may be made. In the intestines these amino-acids may be acted on by bacteria and vari- ous poisonous or objectionable substances formed, like indol, skatol, and others. Some of these produce dele- terious effects if absorbed into the body. The proteins are necessary for life. They are the only form of food which can build up and repair the body, if we accept the fatty tissues, which may be replaced by protein, carbohydrate or fat. They also supply energy and heat. If they are not supplied in sufficient quantity 14 DIETETICS FOR NURSES. the body will waste and a condition of malnutrition come on. Carbohydrates contain no nitrogen. They are com- posed of carbon, hydrogen, and oxygen, the last two in the proportion to form water, hence the name carbohy- drate. They include starch, sugar, and the vegetable fiber or cellulose. Carbohydrates are burnt up in the body and are the most important source of heat and energy. Excesses taken are converted into fat and stored up in the body. The superficial fat of the body protects it from cold and acts as a storehouse for the fat, which can be converted into heat and energy. Fats.-It is the fashion nowadays to group together substances of a greasy feel which are soluble in chloro- form and other fat solvents and insoluble in water. These substances are called lipins, and the term in- cludes a great many substances differing widely in a general way. The principal ones are fats, which are solid or semisolid at ordinary temperatures, as lard; fatty oils which are fluid at room temperature, as olive oil; essential oils which are volatile and usually have a marked odor, as oil of cloves; waxes, as beeswax; and sterols or solid alcohols. There are others of interest to chemists and physiologists. Fat serves the same purpose as the carbohydrates. Fat supplies more heat and energy, weight for weight, than carbohydrates, but is neither so easily digested nor so available. Fat is found in animal and vegetable food, as in the fat part of meat, butter, olive oil, and is present in large quantities in the yolk of egg. Vitamins.-This term is used for several substances, sometimes called food accessory substances, which are at present not fully understood. These substances are present in foods in small and variable quantities. If CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 15 any of them are insufficient in the diet certain rather definite changes occur in the body. These changes may be stopped and health restored by adding foods con- taining the missing substances to the diet, provided the alterations in the body have not progressed too far. They are intimately connected with growth, and at- tention to this factor in the diet of growing children is of the greatest importance. There are at present many conflicting opinions regarding vitamins. The following have been described: Vitamin A, or fat-soluble A, whose absence causes a lack of growth and an eye disease, xerophthalmia. Vitamin B, or water-soluble B, whose absence causes lack of growth and the development of beriberi in man and polyneuritis in fowls. Vitamin C, or the antiscorbutic vitamin, whose ab- sence causes scurvy. Vitamin D, or the calcium-depositing vitamin, whose absence together with a diet deficient in calcium or phosphorus causes rickets. Vitamin A, or Fat-soluble A.-This is found in large quantities in butter fat, cod-liver oil, in glands used for food, such as liver and kidney, sparingly in some animal fats, while in some it is absent. It also occurs in some of the green vegetables, as spinach, cabbage, and the like. When it is absent or deficient in the diet the body wastes, the young animal ceases to grow, and changes occur in the cornea which may eventually de- stroy the sight. Some attribute rickets to a lack of this vitamin. Vitamin B, or Water-soluble B, is present in most foods, but there is a great variation in the quantities. It is present in large amounts in yeast, eggs, milk, meats, especially in glands like liver and kidney, in the germ 16 DIETETICS FOR NURSES. of seeds, in sprouting grain and legumes, in bran, in nuts, in almost all fruits, in almost all vegetables, es- pecially in potatoes and turnips, and in leafy vegetables, such as spinach and cabbage. Polished rice and bolted white flour are particularly deficient in water-soluble B. A deficiency or absence of this vitamin is the cause of beriberi in man, while fowls and certain animals de- velop polyneuritis when fed on diets which do not con- tain it. In preventing or curing beriberi, rice polishings, bran, yeast, the embryos of wheat or rice, whole grain of wheat, milk, and germinating pulses have been found most valuable. Fresh meats and onions are also of service. Vitamin C, or the antiscorbitic vitamin, is found chiefly in plants in the leaves, juices, and roots. The amounts vary. Foods rich in vitamin C are orange juice, lemon juice, fresh or canned tomato juice, potatoes, onions, green salads, as lettuce and romaine, cabbage, beans, and berries. It is present in small quantities in fresh milk. This vitamin is low or lacking in yeast and yeast ex- tracts, embryos of grain, yolk of eggs, olive oil, butter, cod-liver oil, prunes, beets, and foods dried, heated, or cooked for a long time. The Calcium-depositing Vitamin.-Mellanby has shown that a lack or absence of this vitamin will cause rickets when the calcium in the diet is low and the phosphorus sufficient, or when the phosphorus is low and the calcium sufficient. Adding the salts to the diet will not effect a cure, but adding cod-liver oil will. This vitamin is little known, but is present in cod-liver oil, to a less extent in butter, and there is some in plant leaves. Sun- light and certain kinds of artificial light have a marked preventive and healing effect in rickets. The following table, a modification of one given by Atwater, shows the uses of the different food elements: CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 17 Nutritive Ingredients of Food. Edible portion-e. g., flesh of meat, yolk and white of egg, wheat, flour, etc. Water. Food as purchased contains- Protein. Fats. Carbohydrates. Mineral matter. Nutrients Refuse-e. g., bones, entrails, shells, bran, etc. Uses of Nutrients in the Body. Protein-forms tissues-e. g., white (albumin) of eggs curd (casein) of milk, lean meat, gluten of wheat, etc. Fats-are stored as fat-e. g., fat of meat, butter, olive oil, oils of corn, wheat, etc. Carbohydrates-are transformed into fat-e. g., sugars, starches, etc. Mineral matters (ash)-share in forming bone, assist in digestion-e. g., phosphates of lime, etc., potash, soda, etc. All serve as fuel to yield energy in the forms of heat and mus- cular power. Vitamins exert an influence on growth and nutrition. The changes which take place in the body in "burn- ing up" the food material are designated metabolism. The heat value of the various foods may be determined by the use of an instrument known as a bomb calor- imeter, the result being expressed in calories. A calorie is the amount of heat that is necessary to raise the tem- perature of one kilogram of water i° C. It is nearly the same as the amount required to raise one pound of water 40 F. This expressed in the mechanical force, that is, the amount of work it would do, means that a calorie would raise a ton about 1.54 feet, or that it is equal to 1.54 foot tons. Some authors use gram calories, and their figures are 1000 times greater than those in most general use. According to Atwater, the fuel-value of the various classes of food as ordinarily supplied is as follows: I gram of protein =4 calories; 1 pound =1820 calories. I " fat =8.9 " ; 1 " ==4040 " I " carbohydrate = 4 " ; I " =1820 " 18 DIETETICS FOR NURSES. These figures are somewhat lower than the figures given by older estimations, and are based upon the most recent experiments. The fuel-values formerly given were : protein and carbohydrates, 4.1 calories per gram; fat, 9.3 calories per gram. It will be observed that fat has a very high food-value, which doubtless explains why it is stored up as a reserve fuel. The amount of energy used in mental work has never been determined. In an experimental chamber, where as slight an exertion as turning over in bed will be regis- tered by the thermometric scale, no change was produced by the inmate working out the most difficult mathematic problems. Acids and Alkalis.-Another side of nutrition that is being studied to great practical advantage is the sub- ject of acid production on the body. When the body is starved, late in diabetes and in other conditions, the fats which should be oxidized or burnt up in the body and finally be excreted as water and carbon dioxid are side- tracked, as it were, and form certain acids which are poi- sonous. The body, to offset this condition, furnishes ammonia, and the overproduction of acid in the body may be studied by observing the amount of ammonia excreted. Sometimes sodium bicarbonate is given for its alkaline effect. Certain foods are used in the body with the ultimate production of acids, as examples: meats, cereals, and prunes; other foods furnish alkalis or bases, as potatoes, apples, cantaloupes. Milk is half- way between the two extremes. In overproduction of acids the foods which furnish bases (alkalis) may be chosen to form a major part of the diet. Acidosis.-The body is normally alkaline in spite of the fact that acids are being constantly formed in the process of nutrition. Carbonic acid, as given off in CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 19 respiration as carbon dioxici, and the acid urine take away others. The remainder is neutralized by the forma- tion of ammonia. There is also a reserve supply of alkalis in the tissue. When, owing to faulty metab- olism, there is an overproduction of acids or a lessened excretion of them, a condition known as acidosis comes on. This is seen chiefly in cyclic vomiting, after anes- thesia, in severe diarrhea, and in diabetes. This condi- tion is sometimes combated by giving sodium bicarbon- ate by mouth, by rectum, and sometimes intravenously or subcutaneously. DIGESTION AND ABSORPTION. The digestion of food takes place through a number of changes brought about by the action of a number of fer- ments or, as they are often called, enzymes. The food is so changed that the useful part can be absorbed and used by the body, while the remainder is passed off as refuse. Enzymes are supplied by a number of glands, as ptyalin in the saliva, pepsin in the gastric juice, and trypsin in the intestine. There are enzymes which change starch into sugar, some which change protein into soluble sub- stances, others which break up fats, still others acting on sugars, etc. The chemistry of these changes is usually that the enzyme causes the food substance to unite with water and separate into two simpler compounds. On being taken into the mouth the food is broken up by chewing and mixed with the salivary juice, which acts on the starches and changes them into sugar. The chemic reaction of the saliva is alkaline. The food then passes into the stomach. The chemic reaction of the stomach or gastric juice is acid, and the action of the salivary juice is soon stopped. In the stomach the food is liquified and the proteins changed into peptones by the action of the pepsin. Milk is curdled by the action of 20 DIETETICS FOR NURSES. another enzyme-rennin. Appetite is a great factor in the secretion of the gastric juice, as Pawlow and others have shown. Food introduced without the knowledge of the individual is not digested as rapidly, nor as much gastric juice secreted, as when the appetite has been excited. After digestion has begun there are certain substances which cause a second and more uniform flow of gastric juice. These have been called hormones. The bodies which most easily cause this flow of gastric juice are the products of protein digestion, so that where the flow has been started by appetite it goes on more satisfactorily. Meat juices also contain such substances, and meat soups or broths are, therefore, very useful in stimulating the flow of gastric juice. After from one to several hours, according to the quality and quantity of food taken, the liquid mixture in the stomach is passed into the intestines. Here the reaction is alkaline. A number of different juices act on the food at the same time. The liver supplies bile, the pancreatic gland a juice, the intestinal glands a secretion. The pancreatic juice contains several enzymes : trypsin, which acts like pepsin ; amylopsin, which acts like ptyalin, so that the digestion commenced in the mouth and stom- ach is completed. It also contains steapsin, which acts on the fats, emulsifying them, that is, dividing them into little droplets like cream or a cod-liver oil emulsion, and also splitting the fats into glycerin and fatty acids. The bile from the liver assists in emulsifying fat and exerts an influence over the food, hindering putrefaction. The in- testinal juices aid in emulsifying fats, and act upon the starches and sugars. Absorption.-This occurs in two ways: either by the material absorbed entering directly into the blood through the capillaries in the intestines, and passing CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 21 thence through the portal veins, or it is absorbed by little vessels in the lining of the intestine called lacteals, and from these it passes through the thoracic duct, a long tube connecting them with the veins (left jugular and subclavian), returning the blood from the upper part of the body. The food material in the second case enters directly into the blood-current. Little or no absorption takes place in the stomach. The food enters the small intestine in a liquid condition and remains from 5 to 20 hours, and is then passed into the large intestine, where the excess of water is absorbed and the refuse or feces passed off in a more or less solid form. Almost all the absorption of food takes place in the small intestine. The large intestine may absorb food under certain conditions, as when it is injected into the bowel (see Rectal enemata). The liver plays an important part in nutrition. It supplies bile, but that is a small matter compared to what is called its glycogenic function. The carbohydrate food, on reaching the liver, is changed to glycogen or animal starch. This glycogen is stored up in the liver and also in the muscles, and is burnt up in muscular action. The liver also takes care of the waste formed by the changes taking place in the body. These waste products are brought to the liver by the blood and changed into compounds which can be passed off from the body. There are a number of waste products, most important of which is urea, which may also be formed in the mus- cles. This urea enters the blood-stream and is passed off by the kidneys. The Digestion of Infants.-The salivary digestion is very feeble in early life. The salivary glands are fairly active by the fourth month, and begin to play a more important role in the digestion about the eighth or ninth 22 DIETETICS FOR NURSES. month. The stomach digestion is of less importance in infancy. One of the principal changes is the coagulation of the casein (curd) of milk. THE RELATION OF FOOD TO VARIOUS CONDITIONS. Heredity.-Certain diseases or conditions which are affected by diet are apt to run in families, the most im- portant of these are obesity, gout, diabetes, and alcohol- ism. Food idiosyncrasies may be often inherited, as the urticaria (hives) caused by eating strawberries or shell- fish. Sex.-Women, as a rule, require about four-fifths as much food as men, this may partly be due to the seden- tary life led. Age.-Children require proportionately more food than adults. Atwater gives the following table of food requirements: Boy of 15-16 years requires 0.9 the food of a man at moderate work. Girl of 15-16 " 0.8 " " " Boy of 13-14 " 0.8 " " " Girl of 13-14 " 0.7 " " " Boy of 12 " 0.7 " " " Girl of 10-12 " 0.6 " " " Boy of xo-11 " 0.6 " " " Child of 6-9 " 0.5 " " " Child of 2-5 " 0.4 " " " Child under 2 " 0.3 " " " Old people require less than vigorous adults. Race and Climate.-Various races use different diets, depending much on the climate they live in. Cli- mate affects the diet largely by the supply it affords. More fat is required in cold climates and during cold weather than in warm. The well clad require less food than those exposed to cold. Si^e and Weight.-Other things being equal, the larger the body the more food is needed. CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 23 Rest and Exercise.-Much less food is required during rest than during exercise. In exercise the mus- cular activity increases oxidation and tissue waste, and this waste must be counterbalanced by an increased con- sumption of food. Individual tendencies have some effect on the amount of food required. Some persons are obese and eat but little, and vice versa. THE INFLUENCE OF VARIOUS FACTORS UPON THE DIGESTION. Apart from the selection of a proper diet, important factors that especially affect the digestion are the follow- ing: i. The hours, order, and frequency of meals. 2- Variety in diet. 3. The appetite. 4. The temperature of food. 5. Rest and exercise before and after meals. 6. Emotion. 1. Order and Frequency of Meals.-It is usually customary to fix certain hours for taking of meals; these hours vary with the occupation of the individual. In large cities, where the noon hour is taken up largely with active business pursuits, evening is selected as the most convenient hour for dinner. Sir Henry Thompson states that three general systems are in use, according to which two, three, or four meals are taken daily. The first sys- tem, which consists of two meals a day, is followed in France and other countries on the continent of Europe. A substantial meal, consisting of fish or meat and other courses of solid food, is eaten about noon; no food is taken before the noon meal, except on arising, when a cup of coffee or chocolate and a small quantity of bread and butter are taken. The second meal, which is dinner, is eaten between 6 and 7 o'clock in the evening. This meal is the largest meal of the day, and consists of soup, 24 DIETETICS FOR NURSES. fish, meat, vegetables, salads, dessert, and black coffee. The second system, commonly in vogue in England, con- sists of four meals daily. The first meal, or breakfast, is taken at about 8 a. m., and consists of cocoa, tea or coffee, bread, butter, bacon, fish, or eggs; dinner is eaten be- tween i and 2 p. m. and consists of soup, meat, fish, vege- tables, and pudding; tea is taken at 5 p. m., and supper is served at 8 p. m., and consists of meat, fish, vegetables, and stewed fruits. Dinner is taken in the evening by the well-to-do classes, and a substantial lunch is usually taken at noon. The third system, practised in this country, consists in taking three meals daily. In many towns it is customary to dine at noon; in others, in the evening. The usual breakfast, taken between 7 and 8 a. m., con- sists of fruits, breakfast food or cereals, eggs, bacon or salt fish, tea, cocoa or coffee, and bread and butter. Luncheon, eaten between 12.30 and 2 o'clock, consists of cold meat or a chop, vegetables, salads, and dessert. Dinner, eaten between 6.30 and 8 p. m., is the heaviest meal of the day, and consists of soup, fish, meats, vege- tables, salads, and fruit. The frequency of meals must be regulated according to individual conditions. Patients suffering from diges- tive disturbances and those who take very small quanti- ties of food at a time require nourishment at frequent and regular intervals; whereas, those whose digestion is feeble, should allow six or seven hours to elapse between meals; ordinarily the intervals between meals should be about four or five hours, this being about the time neces- sary for complete digestion of a mixed meal in the stom- ach. The habit of habitually omitting the noon luncheon, so commonly practised by busy Americans, should be discouraged. 2. Variety of Diet.-In order thoroughly to satisfy CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 25 the needs of the body the diet must be varied. Although a diet restricted to but a few articles of food may contain a sufficient quantity of the alimentary principles to sus- tain the body nutrition, yet the monotony of such a diet becomes so objectionable that it cannot be digested thoroughly. With a mixed diet the same person will digest a larger proportion of nutrients than with a diet composed of a single food material. Certain races re- strict the variety of food from religious motives, such as the Jewish restriction of ham, pork, and oysters. 3. Appetite.-Appetite is the desire for food, and is dependent upon various conditions. It is controlled by the sensation of hunger, and is often induced by the sight, smell, and taste of food. Simple bitters or some form of alcoholic drink will at times induce this sensa- tion. The appearance of badly prepared or improperly served food will often dispel the appetite. In children the appetite is usually good, whereas in the aged it is lessened. Some persons have voracious appetites and abnormal craving for food. This is often the case in diabetic and other conditions, when, at times, the appetite cannot be satisfied. 4. Temperature of Food.-The temperature of food when taken is of considerable importance. The ideal temperature is that of the body, from 98° to ioo° F. (Uffelmann). The limits of safety being between 450 and 1300 F. According to Hutchison, extremes of tempera- ture of food are apt to give rise to gastric disturbances, such as gastric catarrh. Uffelmann states that a drink at a temperature of 1220 F. increases the body-tempera- ture 0.1 to 0.30 C. It is believed by many that ulcer of the stomach, so common in cooks, is often due to the taking of too hot foods. 26 DIETETICS FOR NURSES. 5. Rest and Exercise Before and After Meals.- It is often advisable to rest, but not to sleep, after meals. The larger part of the work of the stomach should be completed before retiring at night, otherwise the sleep is apt to be disturbed. About one to two hours should be allowed to elapse between a light evening meal and bedtime, and three to four hours between a heavy meal and sleep. From personal observations the authors have concluded that digestion is improved by rest after meals, but impaired by sleep. In many instances a period of rest before eating meals is a valuable aid to digestion. Violent exercise immediately after meals inhibits diges- tion, whereas moderate exercise one or two hours after meals materially aids this process. 6. Food and Emotion.-Severe mental strain and strong emotion disturb the digestion, and for this reason food should not be taken until a period of rest and com- posure has intervened. On the other hand, pleasurable sensations aid the digestion, and pleasant conversation at the table is, therefore, to be recommended. ABSORPTION OF FOODS. Food absorption takes place chiefly in the small intes- tine ; in the stomach and in the large intestine it takes place only to a limited degree. In determining the de- gree of absorbability of food, the amount of the element- ary food principles ingested must first be ascertained, and the proportion that has not been absorbed determined from the feces. The degree of absorbability of a food indicates, in a measure, its nutritive value. According to Atwater,1 from an ordinary mixed meal an average of 1 Principles of Nutrition and Nutritive Value of Food, Farmers' Bulletin No. 142, United States Department of Agriculture. CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 27 92 per cent, of protein, 95 per cent, of fats, and 97 per cent, of carbohydrates is absorbed in the body. " The proportion of the several nutrients which the body re- tains for its use are commonly called percentages or coefficients of digestibility." The following table, taken from Atwater, gives these coefficients of digestibility: Coefficients of Digestibility and Fuel-value per Pound of Nutrients in Different Groups of Food-materials.

The proteins of animal food are much more completely absorbed than are those of vege- table origin. Absorption of Fats.-Fats, like proteins, are ab- sorbed mainly in the small intestine. This absorption of fat is very complete. Absorption of Carbohydrates.-Carbohydrates are absorbed more completely than either the fats or the pro- 28 DIETETICS FOR NURSES. teins ; consequently, these foods leave but a small residue in the intestine. As Rubner, Atwater, and others have pointed out, foods taken in combination are absorbed more completely than when taken alone. Atwater has shown that the following proportions of the alimentary principles are absorbed when the individual takes a mixed diet: Protein. Fat. Carbohydrates. Animal foods . 98 per cent. 97 per cent. 100 per cent. Cereals and sugars . . . . 85 " 96 " 98 " Vegetables and fruits. . . 80 " 90 " 95 " Food that leaves a small quantity of unabsorbed residue in the intestine is not undesirable, in that this residue stimulates peristalsis and thus regulates the condition of the bowels. Absorption of Meat.-Meat leaves a very small residue in the intestines-about 3 per cent, of that ingested is not absorbed. On this account meat is a most valu- able article of food. Absorption of Fish.-Fish is very completely ab- sorbed in the intestines. According to Langworthy, 95 per cent, of total solids, 97 per cent, of protein and 90 per cent, of fat are absorbed. Absorption of Milk.-When milk is taken alone, only 90 per cent, of the constituents are absorbed; if two liters of milk are taken daily, the loss of dry sub- stance, according to Rubner, is 5.7 to 7.8 per cent.; if three liters, the loss is 10.2 to 11.6 per cent. When taken with other foods, however, milk is much more com- pletely absorbed. Infants and children absorb milk much more completely than do adults. In childhood milk leaves a residue of 4 per per cent., whereas in adults 10 per cent, is not absorbed. Absorption of Eggs.-Eggs are very thoroughly CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 29 absorbed in the intestine. Rubner states that hard-boiled eggs are absorbed almost as completely as meat, only 5 per cent, being lost. Absorption of Vegetable Foods.-Vegetables are more or less completely absorbed in the intestine. If the bulk of the vegetables is not too great and the amount of cellulose is not too large, they will be almost entirely absorbed. On account of their bulk and the large pro- portions of cellulose which they contain, most vegetables are, however, incompletely absorbed. The protein is here the element that is not absorbed completely, the carbohydrates and fats undergoing complete absorption. Absorption of Cereals.-Such cereals as rice are very completely absorbed ; the starch is entirely absorbed, and 19 per cent, of the protein is lost. Absorption of I/egumes.-The legumes, such as peas and beans, if given in a finely divided state, are very completely absorbed. Rubner finds that even when given in amounts of 600 grams daily the loss is but slight. If, however, these substances are not given in a finely divided state, the loss in proteins is very great-according to Rubner, as high as 40 per cent. Absorption of Roots and Tubers.-The absorption of roots and tubers, such as carrots, potatoes, etc., depends upon the quantity of cellulose they contain. Inasmuch as the potato contains but little cellulose, it is very com- pletely absorbed. Absorption of Green Vegetables.-Most green vegetables are very incompletely absorbed in the intes- tine. They leave a large residue, which acts as a stimu- lant to intestinal peristalsis. Absorption of Fruits.-Fruits, like green vegeta- bles, are usually incompletely absorbed; according to 30 DIETETICS FOR NURSES. Hutchinson, 80 per cent, of the protein, 90 per cent, of the fat, and 95 per cent, of the carbohydrates are ordi- narily absorbed. QUANTITY OF FOOD REQUIRED. This varies necessarily under special conditions. The adult requires more food than does the child; a man at work more than one at rest; an emaciated individual less than when he was in robust condition. The selection of a proper diet is dependent upon a knowledge of the amount of the four alimentary substances-proteins, car- bohydrates, fats, and vitamins-necessary to maintain the nutritive equilibrium and consequently the body weight. Dietaries are formulated by computing the quantities of the alimentary principles required under special con- ditions. Protein.-The quantity of protein disintegrated daily by a fasting healthy individual weighing 70 kilograms is 60 grams; it is obvious, therefore, that at least this amount should always be present in every computed dietary. Ordinarily from 100 to 125 grams of protein are con- sumed daily. As has been stated elsewhere, 1 gram of fat can replace 2.4 grams of protein or carbohydrates and the protein can replace and be partly replaced by the carbohydrates and fats. Fats and carbohydrates are, therefore, protein economizers. That part of the protein, however, required for organization of the body cannot be replaced by the carbohydrates or fats. how Protein Standards.-Chittenden and others believe that the best diet is that which contains the small- est amount needed to maintain life, together with fat and carbohydrates to cover the needed calories. They urge that health and weight may be maintained on this, and CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 31 that mental and physical efficiency is greater than when more food is taken. They believe that the protein is oxi- dized by the formation of substances more or less difficult of excretion, and that the presence and excretion of these products increase the wear and tear of the body without increasing its efficiency. There is no question that such diets may be taken and the individual still maintain health, and the experiments are of especial value in teach- ing us that in various diseases, such as gout, nephritis, and others in which it is desirable to reduce the protein to a minimum, that small amounts of protein are not in- compatible with health and efficiency. There would seem to be certain objections to the continued use of a diet very low in protein, and it has been suggested that it renders the body less resistant to infection, and that it may also ultimately cause certain disturbances of metab- olism. In certain cases the increased amounts of fat and carbohydrates necessary may mean undesirable bulk and strain on the digestive organs. Protein Optimum.-The best amount of protein for an individual is still an open question. For a person of average size it is probably not well to go over 120 grams a day or under 60. This leaves a rather wide range, and it is safe to say that the optimum lies between the two. In certain diseases, as in tuberculosis, increases may be made above the maximum limit, and in certain diseases, as in nephritis and fevers, the amount may be reduced. In some diseases the kind of protein is a matter of con- siderable importance, and this is probably true of gout. Purin Metabolism. (See also Gout?)-Certain forms of protein contain nitrogen in a form called the purin basis or purin bodies. These substances occur in such foods as liver and sweet bread, and is, to a somewhat less extent, in other meats, and they are also found in legumes 32 DIETETICS FOR NURSES. and in some other food. The products from these bodies are difficult of excretion, and in certain diseases it is a good thing to lessen the amount taken, particularly in nephritis and gout. The foods which contain the largest amounts are of the meats, liver, kidney, sweet breads, and beef tea and pigeon; of the fish, herring, sardines, sardellen, and anchovis; of vegetables, mushrooms and spinach, although there is less in these substances than in ordinary meat. Peas, beans, and lentils of various kinds also contain considerable amounts, while milk, cheese and eggs, most vegetables, fruit, cereals, and bread- stuffs are free from purin nitrogen. There is a question about oatmeal, and it is generally ordered omitted from diets where the excretion of nitrogen is difficult. Carbohydrates and Fats.-Carbohydrates diminish nitrogenous waste and are also sparers of the fats, 240 grams of carbohydrates being equal to 100 grams of fat. If 100 grams of protein are taken and absorbed with 600 grams of carbohydrates, the amount of fat can be completely protected. Fat alone, however, cannot check the waste of the nitrogenous tissues. The inges- tion of large quantities of fat increases the accumulation of fat in the body, and this continues until the quantity administered reaches 300 grams, when no more can be digested. Gelatin is a valuable protector of protein, 100 grams of gelatin being equivalent to about 35 grams of protein or 200 grams of carbohydrates; it does not, however, protect against fat loss so well as do carbo- hydrates or fat, 100 grams of gelatin being equiva- lent to about 25 grams of fat. Ordinarily about 500 grams of carbohydrates and 50 grams of fat are consumed daily. Protein, Carbohydrates, and Fats in Combina- tion.-If fat is combined with the protein, less than half CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 33 the quantity of protein is required to maintain the nitrog- enous equilibrium. If more protein, fat, or carbohy- drate be supplied under these conditions, fat will be de- posited in the tissues. Inasmuch as food contains a vari- able proportion of proteins, carbohydrates, and fats combined, the food-value must be determined from the standpoint of the combined effect of the three alimentary principles contained therein. In order to supply the requirements of the organism a certain amount of potential energy is needed to over- balance the amount dissipated in waste and in the pro- duction of body-heat. More potential energy is consumed during work than when the individual is at rest. The following table, computed by Rubner, shows the daily heat consumption, in units of heat (calories), in an adult, weighing 65 kilograms: During rest in bed .... 1800 calories or 28 calories per kilo. In repose 2100 " " 32 " " " In light work 2300 " " 33 " " " In moderate work .... 2600 " " 40 " " " In hard work 3100 " " 48 " " " From Rubner's investigations we learn that1- 1 gm. of protein = 4.1 calories. I gm. of fat = 9.3 " I gm. of carbohydrates = 4.1 " It has also been determined that 1 gram of alcohol equals 7 calories. In other words, the number of grams of proteins, fats, and carbohydrates required daily can be converted into their calorimetric equivalents, and inas- much as we have already seen that the alimentary princi- ples can in a degree be substituted for one another (law of isodynamics), the daily food requirements can be easily 1 Compare Atwater's determinations on p. I J, Dietary computations differ slightly, owing to the fact that some use Rubner's standards and some Atwater's. 34 DIETETICS FOR NURSES. estimated in calories of heat. Thus, in order to calculate the caloric value of any food in preparing a dietary, the number of grams of proteins contained are multiplied by 4.1 ; the number of grams of fat by 9.3 ; and the number of grams of carbohydrates by 4.1; the total is then ascer- tained by adding. Bearing the weight of the individual in mind, a dietary can easily be constructed according to the following method: The quantity of protein consumed daily is loo gm. X = 410 " " carbohydrates " " 500 " X4 I = 2O5° " " fats " " 50 " X 9-3 = 465 2925 The average number of calories required daily in an individual, according to this calculation, is therefore 3000. While diet-lists are easily prepared according to the method just outlined, it must always be remembered that the digestibility and absorbability of food play a most important role and are not to be neglected in formulating the dietary; for while a certain food may contain a great many more calories than an equal weight of another food, yet its relative indigestibility makes it less available as an article of diet. For example, while 4 ounces of sausage produce 510 heat calories, 4 ounces of cheese 520, and 4 ounces of beef only 280, yet the beef is far more digestible than either the sausage or cheese, and thus more valuable as an article of food. As has been aptly said, " We live not upon what we eat, but upon what we digest." Therefore, a diet-list giving quantities of food principles or calories is useful only as it suggests general principles that may be modified to meet individual conditions in health and in disease.

This may be expressed as Protein : Carbohydrate + 2^ Fat : : I : x „ Carbohydrate + 2j^ Fat r' Protein. In other words, it expresses the ratio between the amount of digestible protein and the amount of digestible carbo- hydrates plus the digestible fats. The fats are expressed in terms of carbohydrates, and I gram of fat is considered equal to grams of carbohydrate. For example, in Voit's standard dietary, there is Protein 118 grams. Fats 56 " Carbohydrates 500 " CHEMISTRY AND PHYSIOLOGY OF DIGESTION. 37 The digestible part may be obtained by using the co- efficients of digestibility, and we find these amounts: Digestible protein Il6 x 0.92 = 108.56 Digestible fat 56 x 0.95 = 53.20 Digestible carbohydrates 500 x 0.97 = 485 The fat in terms of carbohydrates is 52.20 X 2.25 = 119.7. The total fat and carbohydrate in terms of carbohy- drates is 485 + 119.7 = 604.7. The nutritive ratio is 108.56 : 604.7 or 1 : 5.5. Under ordinary conditions the ratio should not vary below 5 nor above 7. Of late the tendency is to widen the ratio, that is, to increase the carbohydrate factor. The table on pages 38 and 39 was prepared by the nurses in the class in dietetics in the Johns Hopkins Training School.

Animal foods contain much digestible matter, chiefly proteins, a considerable quantity of fat, in some foods carbohydrates, and, in addition, water and mineral salts. Being thoroughly digested, they leave but little residue in the intestine. The various forms of animal foods- milk, meat, fish, and gelatin-will now be described. ANIMAL FOODS. MILK AND MILK PRODUCTION. Milk, the most important of animal foods, contains all the elements necessary for the maintenance of life, and constitutes a complete food. Composition.-Milk contains varying proportions of each of the four classes of food principles, protein, fats, carbohydrates, and mineral salts, and 84 to 90 per cent, of water, this latter varying with the quality of the milk. In a general way this is true of all milks, which are more or less alike, but which contain different percentages of the constituents. Milk forms the exclusive diet for young, growing mammals, but owing to the fact that the proportions of protein and fat are in excess of the carbohydrates, it is unsuited as an exclusive diet for adults. Unless other- wise stated, cows' milk is meant by milk in this volume. Cows' milk is most extensively used for food, but the milk of goats, asses, and some other animals is used to some extent. Fresh cows' milk has a sweetish taste, a 40 CLASSES OF FOODS. 41 characteristic odor, and is yellowish white in color. On standing it separates in two distinct layers, the upper being more yellow in color, of lighter specific gravity, and containing more fat. For dietetic purposes it is well to think of cream as milk containing varying proportions of fat. The lower part, called skim milk after the re- moval of the cream, is of a bluish-white color, and may be considered relatively free from fat. The specific gravity of milk varies from 1.027 to 1.035, and it freezes at a slightly lower temperature than water. Freshly drawn, the milk of most carnivora is acid to the litmus reaction, human milk is usually alkaline, though not always, and cows' milk usually neither one nor the other, but becoming acid' soon after milking. The principal nitrogenous compound of milk is casein, which differs from the other protein compounds in that it contains both phosphorous and sulphur. Milk also con- tains other proteins, as lactalbumin, which is similar to the serum albumin of the blood. The total proteins aver- ages about 3.3 per cent, of the bulk of the milk, or about 25 per cent, of the total solids. The fats of milk consist of the glycerids of palmitic, stearic, and oleic acids. The fat is suspended in the milk in the form of minute glob- ules, which give the milk its white color and opacity. The fat globules in some milks are larger than in others, and they are smallest from a herd of mixed common cows and largest in the milk of Jerseys and Guernseys. Fat averages about 4 per cent, of the milk, or about 31 per cent, of the total solids. The chief carbohydrate of milk is lactose, or milk-sugar, which is not nearly so sweet as ordinary sugar, and is less soluble in water. In the presence of the lactic acid bacil- lus it is converted into lactic acid, which causes the milk 42 DIETETICS FOR NURSES. to turn sour. Lactose forms about 38 per cent, of the total solids. Milk contains about 0.7 per cent, of salts, which exist chiefly in the form of phosphates, chlorides, and sulphates. Calcium salts, which are found in the milk, are very es- sential to young, growing animals, inasmuch as they play a very important part in the formation of bone. Variations in Milk.-There are wide variations in the composition of the milk of different animals. While human milk contains more sugar and less protein than cows' milk, the full value is about the same. Dogs' milk seems to be the richest, while that which comes from the horse is exceedingly poor, as may be seen from the fol- lowing table: Comparative Composition of Various Kinds of Milk.x Kind of milk.

These may be attributed to many causes, the breed and 1 Konig, Chemie der menschlichen Nahrungs- und Genussmittel, 3d ed., vol. i., pp. 267-362. CLASSES OF FOODS. 43 conditions of the animals, and the food and care they receive being responsible, in a great degree, for these changes. As a rule, a young cow gives better milk than an old one, and a well-fed animal yields richer milk than one that is poorly fed. The milk flow is greater shortly after calving, but the milk increases in richness as the quantity becomes smaller. Milk also contains certain ferments, and there may be specific ferments which ex- plains the desirability of milk of a particular species as food for animals belonging to it. Action of Heat.-The amount of change taking place in milk on heating depends upon the degree of heat and length of exposure. Heating up to 6o° C. does not appreciably change the appearance or taste, although some changes, which defy detection, evidently occur. When milk reaches a little over 6o° C., a scum, composed largely of fatty matter and casein, forms on the surface. Acid milks are coagulated more easily and more quickly than milk which is not acid. Boiling milk changes its taste and color, the cream will not rise as quickly, if at all, and it is less easily coagulated by the action of rennet, and less easily pancreatized. The change in color is due to the production of a certain amount of caramel from the milk-sugar. Some of the more complicated com- pounds are broken up and some of the salts are pre- cipitated. Sterilisation and Pasteurisation.-Heat is em- ployed very frequently in keeping milk, and there are two methods in vogue, spoken of as sterilization and pasteurization. Sterilization of milk is accomplished either by boiling, preferably in the vessel in which it is to be kept, or by placing the bottles. in one of the numerous forms of 44 DIETETICS FOR NURSES. sterilizers that are on the market. The essential part of the process is that the milk is heated to 212° F., and maintained at that temperature, or for ten minutes or longer, suffi- cient to kill off the living bacteria which the milk contains. It is to be noted, however, that the spores and spore-bearing bacteria are not killed by this temperature, and that if the milk is kept under suitable conditions for bacterial growth, bacteria will develop from the spores and the milk may spoil in consequence. In order to secure perfectly sterile milk it is, therefore, neces- sary to repeat the sterilization three times on three successive days. In practical work this is rarely done, except in the production of culture- media for bacterial researches or in preparing milk for long voyages. Ordinarily, milk heated once and then kept cold, 400 or under, will keep perfectly well till the length of time required in its ordinary consumption. There are certain objections to sterilized milk. Certain changes are pro- duced in the milk which have been detailed under the heading of the " Effects of Heat." Sterilizing also kills all the ferments, and places the milk in the class of life- less foods. Sterilizing on a large scale has never become popular in America, perhaps on account of the change in taste and the added expense. It may be used with advantage, however, in keeping milk in very hot weather, especially when the ice supply is deficient. By pasteurization is meant the process by which the Fig. i.-Arnold sterilizer. CLASSES OF FOODS. 45 milk is rendered more or less sterile by heating to 167° F., and in some instances to a lower temperature, maintaining this degree of heat for from twenty to forty- five minutes, and then cooling the milk rapidly to 400 or 450, or lower. This degree of temperature is sufficient to kill off most of the bacteria, and especially the patho- genic bacteria, but it does not render the milk absolutely sterile, so that it does not keep as well as that which has been heated to a higher temperature. It has the advan- tage, however, of not changing materially the com- position of the milk. Pasteurized milk should be kept cold or it will spoil nearly as rapidly as unheated milk. It is useful in summer, and in keeping milk which is to be fed to babies, and is being used at the present time very extensively for keeping commercial milk. In the household, for the purpose of infant feeding, pasteurization is done in two ways. Best, by using one of the special forms of pasteurizers, such as Freeman's, which consists of two parts, a pail for the water and receptacle for the bottles of milk. The pail is a simple pail with a cover; there is a groove extending around the pail to indicate the level to which it is to be filled with water, and sup- ports inside for the receptacle for the bottles of milk to rest on. The receptacle for the bottles of milk consists of a series of hollow zinc cylinders fastened together; this fits into the pail, so that the lower end of the cylinders is immersed in the water. This receptacle has two sets of horizontal supports, the upper set continuous around the receptacle, for use while the milk is being heated; the lower interrupted set is used for raising the receptacle during cooling. Such receptacles are made for ten 6-ounce bottles, seven 8-ounce bottles, three 1-pint and one |-pint bottles, and two 1-quart bottles. 46 DIETETICS FOR NURSES. There is also a large apparatus for the use of hospitals or public institutions, which has a receptacle for forty- three 6-ounce or 8-ounce bottles. The apparatus is used in the following way: The pail is filled to the level of the groove with water, covered, and put on the stove, the receptacle for the bottles being left out. The bottles of milk are then filled, stoppered with cotton, and dropped into their places in the cylinders. Sufficient water is poured into each cylinder to surround Fig. 2.-Freeman's Pasteurizer. the body of the bottle. As soon as the water in the pail boils thoroughly it is taken from the stove and set on a mat or table, or other non-conductor, in a place where there is not a draft of wind blowing on it. The lid of the pail is removed and the receptacle placed on the upper continuous supports. The lid is then rapidly put on the pail, and the pail is thus allowed to stand for three-quarters of an hour. During the first fifteen minutes the temperature of the milk rises to about its maximum, or above 65° C., the point desired for pas- teurizing, and remains there the remaining thirty minutes. During the last fifteen minutes the cover of the pail is removed, the receptacle is lifted and given a turn so as to rest on the lower supports, thus bringing the top of the CLASSES OF FOODS. 47 cylinders containing the bottles above the level of the pail. The pail is then put under a cold-water faucet, and the water is allowed to run into the pail and overflow, but it should not run into the cylinders. Thus the hot water is replaced by cold water, and in fifteen minutes the milk in the bottles is of about the temperature of the cold water used. The bottles may then be put into a refrig- erator until required for feeding. This rapid cooling is a most important part of a low-temperature sterilization, the importance of which is apt to be overlooked. When there is no special apparatus at hand, reasonably good results may be obtained by placing the milk bottles in a pail, filling the pail to the height of the milk in the bottles, and bringing just to a boil, then setting to one side for thirty minutes. In commercial pasteurization special forms of apparatus are used, in which large quantities of milk may be heated to the required temperature for twenty minutes. The advantages of pasteurization are that it is a cheap and effective method of preventing the ordinary infectious diseases, which may at times be spread by milk, and doubtless lessens the number of cases of infantile diarrhea. It should be remembered that pasteurization cannot make bad milk good or dirty milk clean, and when used for infants or invalids it must be modified in the same manner as unheated milk. The disadvantages of pasteurized milk are that it is usually done a long way from the place of production, the milk may be spoiled before it is pasteurized, and while the bacteria are for the most part killed, the toxins, which may have been formed, are not destroyed, and so dan- gerous milk may be sold for good milk. This is, however, counterbalanced by the real lessening of infantile diarrhea. 48 DIETETICS FOR NURSES. Another disadvantage is that the milk producer is apt to become careless and trust to pasteurization to kill off the bacteria, instead of using cold and cleanliness. Pasteur- ized milk is popularly supposed to be less digestible than unheated milk, especially for infants. The difference in digestibility of pasteurized and unheated milk is certainly slight, but the best results in infant feeding are obtained with unheated milk. We are of the decided opinion that unheated milk is far superior in the long run where it can be obtained of sufficient purity to permit of its use. There are other objections sometimes urged, such as it favors the development of scurvy. This is evidently true, but is a lesser evil than diarrhea. For infant feeding, unheated milk, when good milk can be obtained and can be kept cold, is best of all. If the weather is warm and the milk not above suspicion, it should be pasteurized. The average city milk in sum- mer should be pasteurized. Sterilizing may be resorted to where the milk supply is very poor and where the ice supply is deficient, and where it has been found that the milk will not keep without it. Sterilizing milk under pressure is rarely resorted to outside of laboratories. A temperature of 220° F. for thirty minutes is ordinarily considered to produce sterile milk, but sometimes even this is insufficient. Digestion of Milk. -When milk enters the stomach it is coagulated by the hydrochloric acid and the rennin of the gastric juice. These curds, or coagula, consist of pre- cipitated casein and a portion of the fat that has become entangled in the curd. They vary in size and consistence according to the amount and the dilution of the milk taken. The casein soon undergoes a change, being con- verted into some form of peptone, and the fat is again CLASSES OF FOODS. 49 liberated. The albuminous envelope of the fat-globules is dissolved and the fat coalesces, forming larger drops, in which condition it passes into the duodenum. A por- tion of the water and some of the salts are absorbed in the stomach. The curd that has not been acted upon by the gastric juice, together with the water, salts, and car- bohydrates that still remain, also pass into the intestine, where their digestion is completed. Boiling increases the digestibility of milk, the precipitate being deposited in a more flocculent form. If the milk is previously diluted with lime-water, barley-water, or one of the aerated waters, such as Vichy, the curds formed are smaller and softer, and the milk often rendered more palatable. Bread and crackers added to milk make a good mechanical diluent by mingling with it and maintaining a soft condi- tion of the curds. The addition of alkalis may be re- sorted to with a view to neutralizing the acids. This has the effect of coagulating the casein more slowly, and forming flocculi rather than cheesy masses. Color of Milk.-Various changes in the color of milk are not uncommon, the best known of which is a blue milk due to the action of bacteria. Red milk may be due to the presence of blood due to injury of the udder or mammary gland, to the cows having fed on plants con- taining red pigments, such as the madder plant, and, more rarely, to the action of bacteria. Green, yellow, chocolate- colored, and black milk have been described, and are also due to the action of bacteria. Slimy or Ropy Milk.-This is a very curious change which occasionally takes place in milk, and is due to the action of certain bacteria. The milk becomes slimy or ropy, and can be drawn out into long, thin threads, even as long as ten feet. In some countries, particularly Nor- 50 DIETETICS FOR NURSES. way, slimy milk is produced by the addition of certain leaves to the milk and the product used as food; the leaves contain the slime-producing bacteria. This change is also induced for the manufacture of certain cheeses, particularly Edam. Bitter Milk.-This is very common, most frequently being caused by the cows having fed on plants contain- ing bitter substances. It may also occur during the last stages of lactation, and sometimes by the presence of cer- tain bacteria. Alkaline Fermentation of Milk.-Milk which has been boiled does not sour through spontaneous fermen- tation, but if exposed to the air at ordinary temperature it becomes alkaline in reaction, sometimes develops a bit- ter taste, and then curdles. Later on the curd dissolves, and a more or less clear fluid is left. These changes are due to bacteria. Flavors in Milk.-The flavor of milk may vary from time to time, and this may be due to the food, such things as wild onion, even in small quantities, affecting the flavor of the milk very markedly; and disorders in the cow may also cause unusual flavors for a few days. Milk also ab- sorbs odors, and if kept in an ice-box with odoriferous substances it may take on their flavor. The growth of bacteria also alters the taste of milk very materially, and may impart many different flavors to it. Bacteria in Milk.-Milk is a most excellent culture- medid for bacteria, and most germs grow luxuriously in it at the expense of the quality of the milk. The changes produced are largely those of decomposition, many of them are exceedingly complex, resulting in the production of changes in the flavor, odor, color, and the quality of the milk. The proteins may become decomposed, the CLASSES OF FOODS. 51 sugar converted into gases, alcohol or acids, while the fats are but little changed. The number of bacteria in milk varies greatly, the very best milk containing but a few thousand bacteria per cubic centimeter, while very poor milk may contain many millions in the same quan- tity. In Rochester, and many other cities, 100,000 per cubic centimeter is regarded as the limit in milk fit for human food. Milk containing more than this should be regarded as unfit for human consumption, and especially for infants and young children. The nature of the bac- teria present is important, as disease-producing germs are dangerous to the public health. As a rule, milk which contains but few bacteria will contain none of the disease- producing varieties, or but very few, while milk contain- ing large numbers of bacteria is very liable to contain those which produce disease. Nearly all the disease- producing bacteria grow better at or near the body tem- perature, and grow slowly, if it at all, in milk which is cold enough to prevent the rapid growth of bacteria. To prevent bacteria in the milk from increasing it should be chilled to 450 or 400 F., and kept at that temperature until used. Each time milk is handled, such as pouring from one vessel to another, there is an increase in the number of bacteria. The chief source of bacteria in the milk is from the dirt which gets in at the time of milking, and from the milk being placed in dirty utensils. Souring; of Milk.-With but few exceptions, milk will sour in various lengths of time, and it may be re- garded as a normal phenomenon. As a matter of fact, milk which does not sour under ordinary conditions should be regarded with suspicion and tested for preservatives. When the milk reaches a certain stage of acidity it DIETETICS FOR NURSES. 52 curdles. Ordinarily the souring of milk is due to one or two varieties of bacteria, but there are many other bacteria which may occasionally cause it to turn. The most com- mon cause of the souring is a germ called the lactic acid bacillus, which grows best when the milk is kept in deep vessels, where the air is more or less excluded. Milk soured by this bacillus has a firm clot with a little whey on top, and is free from gas. When the curd is broken up by shaking, it separates from the whey and sinks to the bottom. Such milk has a pleasant acid taste, and is much used for food, either as clabber or curds and whey or cottage cheese. The next most common acid-producing bacteria grows best when the milk is in shallow pans, and it produces gas, so that the curd is broken up and con- tains gas-bubbles. These bacteria are a source of trouble to manufacturers of cheese. There is a peculiar belief that a thunder shower will sour milk, but it is probable that the conditions which produce thunder showers are those favorable to the growth of bacteria which sour milk, and during the hot weather milk frequently sours apart from thunder storms, and also that milk cooled immediately after milking and kept properly cooled will not sour during a thunder storm. Milk Production.-The production of milk, which will keep a reasonable length of time and be free from objectionable features, is a comparatively simple matter, but it requires care and constant supervision and is best undertaken by persons trained in dairying. The first con- sideration is the cow herself, and to produce good, pure milk the cow must be healthy and must be kept clean. Sick cattle should be separated from the herd, and if a herd is to be kept free from tuberculosis, no cow should be added to it without first having been tested by tuber- CLASSES OF FOODS. 53 culin, and the entire herd should be tested from time to time. The cow should be groomed regularly, the same as a horse, the oftener the better, and this reduces the bacterial contamination of milk very materially. Some dairymen cut off the longer hairs about the flanks and tail to lessen the danger of having them soiled with feces. The grooming should be done before milking, and the cow should not be allowed to lie down until she has been milked. The stables should be clean, light, and airy, and a special milking-room is desirable, unless the barn is of good construction and of sufficient size. Anything which stirs up dust should be avoided. The barnyard should be kept clean and drained. The employees should be healthy and clean, and the hands should be thoroughly scrubbed before milking. Many large dairy farms supply sterile suits to their employees to be worn at milking time. No one who has, or who has recently had, or who is associated in any way with any contagious disease, should be allowed to have anything whatever to do with the milk production. The milk pails and all milk receptacles should be kept clean, and scalded as thoroughly as possible, and steril- izing with live steam should be done wherever practicable. The water supply of the dairy is of great importance, and many large dairy companies now insist upon special examination of the water and water-supply before re- ceiving milk from farms. Specially constructed milk pails, which, in a large measure prevent the dirt and dust from falling into the milk, are sometimes used, and assist in reducing the con- tamination of the milk. The Transportation and Delivery of Milk.- This cannot be fully considered here, but it may be 54 DIETETICS FOR NURSES. stated that the milk should be transported in sterile cans or bottles; that the pouring of milk from one can to another, or to bottles, should only be allowed in a room provided especially for that purpose, free from dust and other source of contamination. The milk should be kept cold the entire time until it reaches the consumer, and by him until used. The selling of milk from open cans in grocery and provision shops should be pro- hibited. The safest method of marketing milk is in sealed bottles, and, unless some other solution of the problem offers, this should be the only way. Selling from cans, the way it is done in the United States, is open to a number of objections, but the public has not been educated to demand pure bottled milk, although much has been done in this direction. Adulteration of Milk.-The most frequent adulter- ation of milk consists in the removal of part of the cream and adding water. In other instances, good milk and skim milk are mixed together; in both instances the consumer is robbed by paying for an article of food which does not have the nutritive value it is commonly sup- posed to possess. The addition of water brings the added danger of contaminating the milk, as a milk dealer, sufficiently unscrupulous to add water to his milk, would be apt to disregard the character of water used, and, as a matter of fact, a number of typhoid epidemics have been caused in this way. Milk is artificially colored, but this practice is not common, as is popularly supposed. Al- most all communities have laws forbidding the adulter- ation of milk in any way. The Use of Preservatives.-Chemical preserva- tives are frequently added to the milk to prevent the growth of bacteria, and it is done after the milk has CLASSES OF FOODS. 55 partly spoiled. The most frequently used articles are: formaldehyd, boric acid, borax, salicylic acid, and benzoic acid. But small amounts are needed to check the growth of bacteria, but the unscrupulous dealer usually adds a great deal more than is necessary. Milk which does not sour within a reasonable length of time, under favorable conditions for souring, should be tested for preservatives. The use of all such preservatives should be prohibited by law. Examination of Milk.-Testing the quality of milk requires a more or less expert knowledge of chemistry and of bacteriology. In testing milk the specific gravity is usually taken by means of a lactometer; the amount of fat present is estimated by use of a special apparatus known as the Babcock testing machine; the amount of protein present may also be estimated; the number and nature of the bacteria present is frequently gone into by bacteriologists, and the milk is tested for the presence of preservatives. Cream.-When milk is allowed to stand undisturbed, the fat droplets, being of lower specific gravity than the remainder of the milk, gradually rise to the top, and the longer the milk stands up to a certain limit the more cream will be found. Creams are usually spoken of with reference to the amount of fat they contain, so one speaks of a 16 per cent, cream, 20 per cent, cream, etc. The cream which rises on average milk after twenty-four hours usually contains about 16 per cent, fat, and is spoken of as gravity cream. Some gravity cream may contain as much as 18 or 20 per cent, fat, while the richer creams are obtained by centrifugalizing the milk. The composition of the various percentages of creams are given in the following table from Holt: 56 DIETETICS FOR NURSES. Whole milk. Cream. I. II. III. IV. V. Fat . . . . 4.00 8.00 12.00 16.00 20.00 40.00 Sugar . . . . 4-5° 4-5° 4.20 4-°5 3-9° 3-oo Protein . • ■ 3-50 3-4° 3-3° 3.20 3°5 2.20 Salts . . • ■ o-75 0.70 0.65 0.60 o-55 o-45 The fat droplets in cream vary in size in the different varieties of cows. In the Alderneys and Guernseys the droplets are larger, less uniform in size, and more numerous than in milk from the ordinary milch cow. The small uniform fat droplets of milk from the average herds are to be preferred in infant feeding. Cream rises best on milk that has been cooled quickly after mixing, and that has been handled but little. Milk which has been shaken up frequently, and frozen and thawed, does not yield as much cream nor as quickly. Skim Milk.-This is the residue remaining after the removal of cream from ordinary milk, and differs from it in having most of the fat removed, and in being slightly richer in casein and milk-sugar. It is easily digested by most people, and is frequently sold as whole milk. Blitter.-Butter is made from milk by churning, which causes the fat globules in the milk to coalesce, thus form- ing a solid mass. It is made most rapidly from cream that has been ripened from twelve to twenty-four hours, and churned at a temperature between 65° and 700 F. In this way butter may be separated in from twelve to thirty minutes. The process of ripening depends on the presence of certain bacteria, and in some creameries in- stead of depending on chance bacterial invasions of the milk, which may produce at times unpleasant flavors, it is the practice to inoculate the milk with a culture of bac- CLASSES OF FOODS. 57 teria known to impart a desirable flavor. On account of the ease with which fresh butter is digested it is one of the most valuable of the fatty foods. When butter is kept too long it becomes rancid, and this is due chiefly to the fermentation of the small amount of casein remaining in the butter. To avoid this the but- ter should be kept cold. Salting is largely used for pre- venting this fermentation. The amount used should not exceed 2 per cent., but should be worked into the butter so that no undissolved particles remain. Butter is often colored, largely because the public still like a dark-yellow color. Anatto is largely used for this purpose. The United States standard for butter is that it should not contain more than 16 per cent, of water nor less than 82.5 per cent, of butter-fat. Renovated butter is made from butter which has be- come rancid, by melting and then washing with water. It is afterward given a better flavor by mixing with a certain amount of sour cream. Buttermilk.-The residue left in the churn is called buttermilk, and is largely used as a beverage, as it is nutritious and easily digested. It contains the casein of the milk in a finely coagulated form, has a pleasant acid taste, and contains lactic-acid bacilli. The buttermilk left after churning fresh milk has approximately the same composition as skim milk. Buttermilk from ripened cream varies somewhat in its composition. A preparation similar to buttermilk is also frequently made from the whole milk by inoculating with lactic-acid bacilli. It has the advantage that it contains all of the fat. Such milk is much in vogue at the present time, and is used in feeding invalids, especially those with certain forms of gastric and intestinal disorders, and in the feed- 58 DIETETICS FOR NURSES. ing of infants. Conserved buttermilk, made somewhat after the manner of condensed milk, is also used, es- pecially for infant feeding. Acidophilus Milk.-Bacillus acidophilus when given by mouth in the form of a milk culture effects an im- plantation and colonization in the intestinal tract pro- ducing a marked decrease in the number of colon organ- isms, and thus supplants many of the intestinal toxico- genic bacteria. This effect is increased by the addition of lactose. Inasmuch as the Bacillus acidophilus is the predominant bacterial constituent of the intestinal flora of the breast-fed infant, but soon disappears when the milk no longer forms the chief part of the child's diet, its implantation in the intestine has been found useful in the treatment of certain intestinal affections. It has been especially found of value in overcoming chronic constipation. Bonnyclabber.-This is soured milk in which the curd and whey are served in the same dish and usually eaten with the addition of sugar. Curd and whey, or junket, is milk where the coagulation has been brought about by the action of rennet. In many instances the whey is removed and used as a food for invalids and infants. Cheese.-Cheese is made of the curd and a certain proportion of the fat of milk, and varies in composition and consistence according to the method employed in the manufacture. The simplest form of cheese is the so- called cottage cheese, in which the curd is separated from the whey and eaten a short time after it is made. The other cheeses are kept a certain length of time to insure ripening. Sometimes the coagulation is produced by ren- net and sometimes by lactic acid, while various forms of bacteria growing in the cheese and also certain moulds CLASSES OF FOODS. 59 impart to the different varieties their peculiar flavors. Some cheeses are hard and some are soft, the difference being due to the amount of pressure used in hardening them. As a rule, the harder cheeses keep very much longer than the softer ones, and the harder the cheese the more indigestible it is. Like milk, cheese may con- tain certain poisonous substances, due to bacterial action, and severe poisoning may follow the eating of such cheese. The average composition of cheese, as shown by Parks, is as follows: Water 36.0 Protein 31.0 Fats 28.5 Salts 4.5 Condensed Milk.-This is manufactured by heating the milk to 212° F. to sterilize it and then evaporating in a vacuum until it becomes thick and jelly-like. To this considerable amounts of cane-sugar are added. In some cities fresh condensed milk may be obtained which has not had sugar added to it. The composition of con- densed milk is as follows : Unsweetened con- Total solids per cent. Protein per cent. Fat per cent. Milk-sugar Cane-sugar per cent. per cent. densed milk • 40 12 12 l6 O Sweetened con- densed milk . 80 12 12 18 40 Condensed milk is largely used as a substitute for fresh milk by many people, is of especial value in the tropics and on voyages, as well as being a useful food under cer- tain conditions for infants. It is easily digested, and the better brands are reasonably pure, but in the dilutions usually used it is too high in sugar percentage and too 60 DIETETICS FOR NURSES. low in fat. It produces fat, pale, flabby babies, with a tendency to rickets and scurvy, and a lowered resistance to infections. On the other hand, it is most valuable in infants with feeble digestive powers, and those who are not gaining in weight, and in hot summer weather is to be recommended where the fresh milk is of questionable purity. (See Infant Feeding.) It should be remembered that condensed milk may be made from dirty milk, and so be objectionable, and that it may contain large numbers of bacteria. We have found Borden's Eagle Brand satis- factory. Among other brands the Anglo-Swiss and the Ideal may be mentioned. Another method of conserving milk, known as the Campbell method, has been recently introduced, and the product is now obtainable in some places. Pure milk is placed in a concentrating vat and warmed to 1400 F. A blast of filtered air is driven through it for about three hours or until the original volume is reduced to one quarter. This is then bottled in sterile bottles. It may be used just as it is in coffee or tea, diluted one-half in place of cream, or with three times the amount of water in place of ordinary milk. The milk is marketed under the name of White Cross Milk. Predigestion of Milk.-Milk may be partly or wholly predigested in order to render it more easily di- gestible for individuals suffering from gastro-intestinal disorders. This process is readily accomplished by add- ing an active preparation of pepsin to acidulated milk and allowing the fermentation to proceed under the influence of heat at the body temperature by immersion in hot water. During this fermentation the casein is partly or completely converted into albumoses. If the process is allowed to continue too long, the milk becomes bitter CLASSES OF FOODS. 61 For this reason it is ordinarily removed from the hot water after a few minutes, and is placed upon ice, which prevents further fermentation. In order to predigest milk in alkaline solution, pancreatin is substituted for pepsin; pancreatization of milk has now largely replaced pepton- ization. In order to effect pancreatization of milk Fair- child's peptonizing tubes are ordinarily employed. These tubes contain 5 grains of pancreatic extract and 15 grains of sodium bicarbonate. Each tube contains sufficient powder to digest one pint of milk. Another easy method of partially pancreatizing milk is by the use of Fairchild's peptogenic milk powder. First dissolve the powder in the water by rubbing and stirring with a spoon, then add the milk and cream ; mix well; heat in a saucepan with constant stirring until blood-warm-not too hot to be agreeably borne by the mouth; keep at about this temper- ature for ten minutes; then bring quickly to boiling-point; pour at once into a clean bottle, shake thoroughly, cork tightly, and place directly on ice or in a very cold place. Where the taste of pancreatized milk proves objection- able, the addition of carbonated waters, or of small quan- tities of coffee, may render it more palatable. The digestibility of milk may be increased by the addition of hot or cold water, or carbonated waters, such as Vichy or Apollinaris, lime-water, oatmeal, or barley- water, or farinaceous foods, such as arrow-root or flour; occasionally small quantities of salt or sodium bicarbonate are helpful. Kumiss, Kefir, and Mattoon.-Kumiss is a fer- mented drink prepared by both lactic acid and alcoholic fermentation. For many centuries it has been made from mares' milk by the natives living near the shores of the Caspian Sea. The milk is obtained from a special 62 DIETETICS FOR NURSES. breed of mares, the animals being fed very carefully. The milk is mixed with a kumiss ferment, the lactic acid ferment converting some of the sugar into lactic acid, while another part of the sugar is converted into alcohol and carbonic acid; a small quantity of casein is digested. The milk is constantly agitated, and the fermentation allowed to proceed for a period of twenty-four hours or more. Kumiss is an acid, effervescing drink, and contains a very small proportion of alcohol. It is very easily digested, being much more digestible than milk. The casein is so finely divided that lumps cannot be formed in the stomach, and it is easily acted upon by the gastric secretion. In the United States it has been prepared from cows' milk, to which the ferment is added. Kumiss Cure.-In certain parts of Russia this form of cure is not uncommon. It consists in drinking small quantities of kumiss, and gradually increasing them until large quantities are taken. Kumiss cures have been prescribed in chronic gastro-intestinal catarrhs and chronic catarrhs of the respiratory tract. Kefir resembles kumiss, and is often used as a substitute for it. It was originally made in the Caucasus from cows' milk, fermented with Saccharomyces mycoderma, lactic acid fermentation going on at the same time. Alcohol, lactic acid, and albumins are formed as a result of the fermentative processes. The casein is partly digested. Tablets of the kefir ferment have been pre- pared by Jurock, and are sold under the name of kefilac tablets. They render the home manufacture of kefir an easy matter. (See Recipes.) Mattoon.-In this form of milk lactic acid is produced CLASSES OF FOODS. 63 by fermentation with a ferment obtained in Syria. It is thicker than kumiss, and does not contain alcohol. Kumiss, kefir, and matzoon are agreeable forms of milk foods, are easily digestible, and are especially useful in those cases in which milk cannot be taken or is not well borne. EGGS. The eggs of the hen are consumed in largest numbers, but those of the duck, turkey, guinea-hen, and of some wild fowl are also eaten. The eggs of the domestic fowls vary in size and appearance, but their composition is about the same. The shell of a hen's egg constitutes 11 parts, the white 57 parts, and the yolk 32 parts of the entire weight of the egg. The table on page 67 shows the composition of hens' eggs, cooked and raw. As may be seen from that table, the egg contains mainly protein and fats, in addition to water and mineral matter. The white and the yolk differ in composition, the white containing more protein and water than the yolk, and scarcely any fat and ash ; whereas the yolk contains considerable fat and ash. The white is said to be pure protein. The flavor of the egg is dependent in a large measure upon the food eaten by the laying hen. Fresh eggs, as is well known, have the finest flavor. If thoroughly macerated, hard-boiled eggs are as digestible as soft-boiled ones. With some persons eggs in any form are indigestible, and produce unpleasant eructations, nausea and headache. Raw eggs are best taken directly from the shell, or they may be combined with milk broths or with coffee. In various diseases accompanied by loss of flesh and 64 DIETETICS FOR NURSES. strength raw eggs in large numbers are prescribed, as many as 24 eggs being given in twenty-four hours. Egg-albumin when raw partly resists digestion. It is absorbed better when slightly heated or diluted. Its palatability may be increased by flavoring it with sherry wine, orange-, lemon-, or grape-juice, or by serving it in cream, cocoa, or coffee. Egg-nog is prepared from milk and eggs, flavored with some alcoholic drink, and sweetened with sugar. Meat forms the flesh or muscular parts of the body. It is one of the most important articles of food and is the chief source of man's protein supply. Meat may be eaten raw or cooked. Raw meat, when well ground up, is very easily digested. Meat is composed of muscle-fibers held together by connective-tissue bands; between the muscle-fibers are bits of fat. As ordinarily seen meat contains muscle- tissue, connective tissues, blood-vessels, nerves, and lymphatics, together with a varying amount of fat. The more fat there is in meat the less water and nitrogenous matter does it contain, and vice versa. Cooking has the effect of rendering the connective tissues soluble, thereby causing a separation of the muscular fibers, allowing the digestive secretion to mingle more thoroughly with them. Cooking also enhances the flavor and appearance of the meat, but, on the other hand, causes a loss in fat and extractives. Cooking likewise destroys the micro- organisms that may be present in the meat and thus renders it more wholesome. Digestibility of Meats.-The digestibility of meat is governed by many conditions: The age at which the MEATS AND MEAT PREPARATIONS. CLASSES OF FOODS. 65 animals eaten were killed, the length of time the meat is kept before eating, the care bestowed upon the animals during life, and the methods of preparing the meats for the table. Meats are most easily digested when stewed; frying renders them most indigestible. Beef.-The composition of beef varies greatly, espe- cially in regard to the amount of fat and water it contains. An ox from three to five years old supplies the best beef. The meat of a very lean animal will contain about 75 per cent, of water and about 2 per cent, of fat. Meat Preparations.-Numerous meat preparations, both solids and liquid, are now on the market, the aim being to produce a concentrated food that will be readily digested. The different beef-juices have but slight nu- tritive value, most of them containing only 4 or 5 per cent, of protein; their chief value lies in the fact that they stimulate the appetite. Bouillons.-Bouillons are prepared by cutting meat into small bits, heating slowly in water for a time, and then boiling it quickly. The fluid thus produced has a very agreeable flavor, but its nutrient value is exceed- ingly small. Beef-extracts.-Beef-extracts are concentrated bouil- lons that are to be diluted at the time they are taken. Their nutritive value is about the same as that of bouillon. Beef-juice.-To produce a nutritious liquid-beef preparation, the meat should be broiled slightly and then cut into small pieces and pressed through a lemon- squeezer or a meat-press. In this way considerable quantities of protein, in addition to the salts and extrac- tives, are obtained. The beef-juices sold on the market, such as Valentine's, are prepared by subjecting the meat 66 DIETETICS FOR NURSES. to a strong pressure. These preparations contain from 5 to io per cent, of protein. Meat Powders.-The nutritive value of these prepa- rations varies greatly. Those most frequently used are a number of peptones, Somatose, and the Mosquera " Beef Meal." Meat-jellies.-Meat-jellies are frequently given to invalids and are an agreeable means of administering protein food. Although they do not entirely replace the protein in the tissues, they produce a considerable quantity of energy. Veal.-Veal is tough and indigestible, especially when obtained from the animals that are killed too young. It differs considerably in flavor from beef. As in many persons veal has a tendency to produce indigestion, it is to be avoided in all cases of digestive debility. Mutton.-Mutton is considered more digestible than beef by English writers, probably because in England the average mutton is more tender than that obtained in the United States; the beef, however, is inferior to that raised in this country. Lamb.-Lamb, when of the right age and tenderness, is as digestible as beef or mutton. Venison.-Unless obtained from young animals, when it is tender, highly-flavored - and short-fibered, venison is apt to be difficult of digestion. Pork.-Pork is the most indigestible of all meats, on account of the large percentage of fat that it contains. Ham and Bacon.-Ham and bacon are both more digestible than pork. In some parts of Germany ham plays quite an important part in invalid dietaries. Bacon is used largely as an army ration. When cooked crisp, thin slices of bacon are easily digested.

Fowl.-Chicken is one of the most digestible and agreeable varieties of meats. The meat of young pi- geons also is especially digestible; that of ducks and geese contains too much fat. The flesh of game is easily digested, the meat of the breast being best adapted for invalid use. FISH. The different kinds of fish vary widely in their nutri- tive and digestive qualities. For example, the flounder and the oyster are much easier of digestion than those that contain a large amount of fat, like the salmon and the herring. Eels contain the greatest proportion of fat, which may reach 28 per cent. White-fleshed fish, as a rule, contain little fat. The table, compiled from Atwater and Langworthy, gives the chemical composition of some animal foods: All fish are best in season; out of season they lose their flavor and have a diminished nutritive value, and in some cases develop an offensive odor. On account of the rapid changes they undergo by way of decomposition, fish should always be eaten in as fresh a condition as possible. Various methods have been resorted to with a view to preventing these changes. There are many modern contrivances for preserving fish, and drying, smoking, pickling, salting and canning are practised on a large scale. Crustaceans.-The most popular of the crustaceans are the crab and the lobster. They are highly nutri- tive, but at the same time highly indigestible. In some persons the crab and the lobster are especially apt to 70 DIETETICS FOR NURSES. bring on nausea, vomiting, and other and more distress- ing conditions. Shell-fish.-Oysters, clams and mussels are the forms of shell-fish chiefly eaten. Oysters, when eaten fresh and raw, constitute the most digestible animal food, but when cooked their digestive value is much lowered. The soft part is proportionately larger and more nutri- tious than the corresponding portion of the clam. The hard or muscular portion is tough and rather indigest- ible, and is best omitted from invalid dietaries. Oysters should never be fried for the sick. Oysters have in many cases been the carriers of typhoid fever, and many persons have been infected in this way. Clams are a popular article of diet and are as agree- able to most palates as oysters. Mussels are consumed chiefly by the poorer classes in the seaport towns of England. VEGETABLE FOODS. Vegetable foods differ from animal foods especially in that they contain a large proportion of starch and sugar and comparatively a small amount of protein. Vegetables do, however, contain a certain amount of proteins and fats. Carbohydrates of Vegetables.-These are starches and sugars. Starch is found in all plants, and is con- verted into dextrin by means of dry heat or by cooking. The starch-granules in vegetables are held together by a cellulose framework. Cellulose is a carbohydrate, but is very insoluble; it can be utilized as a food only when young; when old, it is resistant and cannot be digested and hinders the digestion of the starches enveloped by it.. VEGETABLE FOODS. 71 Protein in Vegetables.-These proteins belong mainly to the globulins. Extractives in Vegetables.-There is a consider- able amount of extractive matter in certain vegetables, such as asparagus, which is not utilized in the body. Fats in Vegetables.-The fats in vegetables are chiefly in the form of oils. In addition, vegetables con- tain a considerable amount of water and salt. The amount of water varies between 70 and 90 per cent. The main mineral constituents are the salts of potash and soda united with organic acids. Digestibility of Vegetables.-The digestion of vegetables takes place mainly in the intestines. Owing to the greater bulk of vegetable food and to the cellulose that surrounds vegetable cells and thus prevents the ready access of the digestive juices, vegetable food is not so easily digested as animal food. For convenience of description the following classification of vegetable foods has been adopted: I. Cereals. 2. Legumes. 3. Roots and tubers. 4. Green vegetables. 5. Fruits. 6. Nuts. 7. Fungi. 8. Lichens. CEREALS. Cereals are the most important food-products derived from the vegetable kingdom. Of this class of foods those in commonest use are wheat, corn, rye, oats, bar- ley, rice and buckwheat. The cereals are eaten chiefly after having been ground into flour or meal. Flour is most commonly made from wheat and rye; whereas corn and oats are the chief sources of meal. 72 DIETETICS FOR NURSES. Wheat is the most important source of flour, owing to the fact that it can be raised in any temperate climate and yields the best flour at the least expense. It is rich in solids and contains little water. Flour is made by grinding the grain of the various cereals. Although flour is made chiefly from wheat and rye, barley, oats, maize, etc., are also manufactured into flour. Bread is made by adding to flour a definite proportion of water, a little salt, and the leavening agent. The mixture or dough is then kneaded, either with the hands or, better, with a spoon. In the large modern bakeries the kneading is done entirely by machinery. After this the dough is set aside for a number of hours, during which time fermentation takes place. It is then molded into loaves and baked. The leavening is dependent upon the action of the yeast on the starch, some of which it converts into sugar, and then into alcohol and carbon dioxid gas. The gas causes bubbles to appear through- out the dough and renders it light and spongy. During the baking process the yeast germs are killed and the alcohol and carbonic-acid gas are driven off. Hot or fresh bread, when masticated, forms a tenacious, doughy mass, and hence is not so digestible as stale bread. Biscuits, pastries, and puddings are made by adding to the flour varying quantities of eggs, sugar, milk, butter, fruit, flavoring extracts, etc. Rice constitutes the staple food of many of the peoples of the Orient. It is grown chiefly in Asia, but is also raised in some parts of Europe. In this country rice culture is confined chiefly to South Carolina. Rice con- tains a large proportion of starch in very digestible form, but is comparatively poor in other constituents. VEGETABLE FOODS. 73 Oatmeal is used to the best advantage in making porridge; owing to its lack of gluten it makes only the poorest kind of bread. What is known as Scotch groats is prepared by freeing the grain from its outer husk. Breakfast Poods.-There are a variety of prepa- rations made from cereals, which have been in recent years placed on the market, the chief characteristics of which are that they have undergone more or less preparation for immediate consumption. For the most part they are sold under trade names; the composition and source of the food is given in some cases and omitted in others. Briefly speaking, they contain about the same amount of nutriment as the cereals from which they are made. Their palatability varies considerably, and there is no objection to the use of such articles of diet if freshly prepared foods are obtained, and the individual that con- sumes them likes the taste. The older packages, unless very carefully put up, are liable to be infected with insects or moulds, both of which render the product unfit for food. The chief objection is the cost, which is far greater than the same amount of food prepared from the cereal itself. LEGUMES. Of the legumes, the pea and the bean are the most important food-products. The legumes contain a liberal proportion of protein (legumen), carbohydrates, and a little fat, besides a large amount of water. Although legumes contain a propor- tion of protein in excess of that of meat, a large amount of fat, and considerable starch, they are less easily digested than animal foods. They contain much indigestible fiber (cellulose), and are also very liable to produce fermenta- 74 DIETETICS FOR NURSES. tion, and in this way occasion flatulence and gastro-intes- tinal distress. The digestibility of the legumes depends largely upon the manner in which they are prepared and the amount that is eaten. A large portion of the legumes ordinarily eaten is imperfectly absorbed by the intestine. Beans form one of the oldest forms of vegetable foods, having been cultivated by the ancient Greeks, Romans, and Egyptians. The numerous varieties used for food have all been improved by cultural methods. There are several varieties of peas, the most important being the field- and the garden-pea. The former is gen- erally used for fodder; but one variety, the Canadian field-pea, is grown for table use. There are many varie- ties of the garden-pea. The lentil is but little used in this country. The chief supply of lentils comes from Egypt, very few being grown in Europe. They form a highly nutritious food. The Soy Bean.-This bean (Glycine hispida), some- times called the soja bean, is an annual leguminous plant extensively used as a food in China and Japan. Until re- cently it has been regarded as a botanic curiosity in the Occident. It has recently been extensively used in America as a forage crop, and to improve the soil if ploughed under. The plant is an erect annual, bearing pods con- taining from two to five beans. There are a large number of different varieties, which vary in size, shape, color, and length of time they take to mature. In the East the bean is used in numerous ways. Some are grown ex- clusively for the oil they contain, and it is used for culi- nary, illuminating, and lubricating purposes. The light- colored beans are eaten in soups, and the pods are some- times picked green, boiled, and served cold, with a sprink- ling of soy sauce. The green varieties are often pickled VEGETABLE FOODS. 75 in brine, and eaten moist or dried with meals as appe- tizers ; the same varieties are often slightly sprouted, scalded, and served with meals in winter as a green vege- table. The bean forms the basis of the so-called soy sauces, used as condiments all over the world. The Oriental races most frequently eat the bean in more or less cheesy-like foods which are prepared from it. It may be used in infant feeding to advantage (see same). Americans may eat the beans in numerous ways, de- scribed under the head of Soy Bean Cookery in the recipes at the end of this book. The bean is of particular value in diabetes (see same). It may be used to increase the protein of the diet. There is some difference in the composition of the different varieties of the bean. An average composition might be stated as water io per cent, protein 35 per cent, and fat 18 per cent. There is also some 8 or 9 per cent, of sugar, and the remainder is made up of fiber and non-nitrogenous extract. The Cereo Company, Tappan, N. Y., have made a flour from this bean, which contains about 45 per cent, of protein, 20 per cent fat, and 9 per cent, sugar. The higher per cent, of protein in the flour is due to the removing of coarse fibrous hulls, which con- tain but little nutriment. Each ounce of this flour con- tains about 13 grams of protein and 120 calories. ROOTS AND TUBERS. Roots and tubers constitute another class of vegetable foods that are of great importance. They contain both starch and sugar, and to these constituentsis due their chief value as a food. On account of the small proportion of protein and the large amount of water they contain, they are inferior in nutritive value to both legumes and cereals. 76 DIETETICS FOR NURSES. The potato is, for several reasons, the most important member of the group. It is a tuber or thickened under- ground stem of the- Solanum tuberosum. It grows equally well in a variety of soils, and when properly cooked is easily digested. The Sweet potato contains more water and sugar but less starch than the white potato. When boiled, it usually becomes mealy, but is often converted into a stringy, sodden mass that is difficult of digestion. The beet contains a very large percentage of starch and sugar. It is raised extensively for the sugar in- dustry, and is also largely employed for making salads to lend variety to the diet. Carrots, when young and tender, form a very nutri- tious food and are greatly relished by many persons. They contain from 85 to 90 per cent, of water. Parsnips, when boiled long enough, form a good food; like carrots, they contain a large proportion of water and a considerable amount of sugar. GREEN VEGETABLES. The green vegetables are valuable not only on account of the amount of nutriment present in them, but for the variety and relish they give to the diet. They contain a large amount of salts and have valuable antiscorbutic properties. Cabbages contain a considerable quantity of sulphur, and on this account are apt to cause flatulence; where digestion is good, however, they are considered a whole- some form of food. Cauliflower is the most digestible member of the cab- bage family. It may be eaten either as a salad or boiled and served with a milk-sauce. VEGETABLE FOODS. 77 Spinach is a popular form of vegetable and is used to a great extent. It is valuable chiefly for its laxative effect. Lettuce is the most important representative of a group of vegetables usually eaten raw. It is made into salad and dressed with vinegar. The various cresses also belong to this class. Celery, which is usually eaten raw, is stringy and has scarcely any nutritive value. Cooked in milk it forms a wholesome and digestible article of food. Tomatoes are eaten both raw and cooked, and are refreshing, generally liked, and easily digested. They are used to flavor broths and are valuable for canning purposes, inasmuch as they retain their flavor better than most vegetables. Asparagus is highly esteemed for its delicate flavor. It is easily digested, even by invalids. It has a slightly diuretic action, and imparts a most offensive odor to the urine, which persists for from twelve to twenty-four hours. Vegetarianism.-It will not be out of place here to point out the disadvantages of an exclusive vegetable diet. Vegetarians are those who subsist almost entirely upon vegetables, cereals, fruits, and nuts; exceptionally milk and eggs are added to their diet-list. It is quite possible, by the eating of vegetables alone, to supply all the food constituents-carbohydrates, fats, and proteins- that are required by the body. Proteins are obtained partly from vegetables, milk, and eggs; those derived from vegetables, however, are digested with much more difficulty and absorbed to a much slighter degree than those derived from animal food. Persons subsisting on a purely vegetable diet for any great length of time are apt to lose strength, as well as physical and mental vigor and endurance. Laborers are unable to perform the 78 DIETETICS FOR NURSES. same amount of work they could accomplish on a diet containing animal food. While vegetables contain large proportions of proteins, in order to supply them in suffi- cient amount very large quantities must be eaten. This overfeeding is apt in many instances to produce digestive disturbances, particularly in those suffering from gastro- intestinal disorders. A purely vegetable diet, if persisted in, is also said to lessen the power of resisting disease. Fruits are of little value as nutriment, and are useful mainly to give variety to the diet. They are used ex- tensively as flavoring agents. The chief nutritive con- stituent of fruits is sugar, and they also contain a small amount of nitrogenous matters, cellulose, starches, organic acids, and a vegetable jelly called pectin, which causes fruit to gelatinize when boiled. The sugar present in fruit is mainly fruit-sugar, or levulose, but some fruits contain, in addition, considerable cane-sugar. In general, fruits contain a large amount of water. The mineral elements of fruit consist of potash, united with tartaric, citric, and malic acids. The flavor and odor of fruits are due to the presence of essential oils and compound ethers. The digestibility of fruits varies with the kind of fruit eaten and its mode of preparation; stewed fruits are more easily digestible than raw fruits. Among the more easily digestible fruits are oranges, lemons, grapes and peaches; raw apples, pears and bananas are some- what less digestible. Oranges and lemons are used in invalid dietaries, their juice allaying thirst very effectively. Apples are wholesome, digestible, and slightly laxa- tive. FRUITS. VEGETABLE FOODS. 79 Pears are, as a rule, more easily digestible than apples. Peaches are wholesome and digestible. They contain less sugar than most fruits. Bananas are the most nutritious of the raw fruits. Grapes contain a large amount of water and consider- able sugar. When thoroughly ripe they are very digestible. Raisins are prepared by drying grapes, the white ones being those most used. Plums and green gages are quite digestible when fully ripe. Prunes are dried plums. They contain much sugar and are markedly laxative in their effect. Olives have a bitter taste and are eaten chiefly as a relish with salads. Their nutritive value is due to the oil they contain. Strawberries are very wholesome unless taken in excess. Currants, gooseberries, raspberries, huckleberries, mul- berries, and a few other berries a contain considerable amount of free acids. They have slightly laxative prop- erties. Melons contain over 95 per cent, of water and about 5 per cent, of other constituents; they are considered indi- gestible. Figs and dates contain large quantities of sugar. The value of the date as a food to the Arab is well known. The avocado, or alligator-pear, contains about 2 per cent, of protein, 20 per cent, of fat, and 7 per cent, of sugar. It is one of the few fruits containing much fat. NUTS. Nuts contain a large quantity of fat and a somewhat larger proportion of protein. They have but little food value and are eaten mainly as a dessert. The average composition of nuts is: 80 DIETETICS FOR NURSES. Water I- 4 per cent. Protein 6-15 " Fats 4<>-5o " Carbohydrates 6-10 " Owing to the large amount of cellulose as well as the large proportion of fat they contain, nuts are not easily digested. The dense cellulose framework which makes nuts so indigestible can be destroyed by grinding, and thus the nut made more easily digestible; such prepara- tions as Nuttolene, Bromose, and Nutmeal, of the Battle Creek Sanitarium Company, are prepared in this way. Almonds contain much fat, but no starch and very little sugar. Chestnuts contain a small amount of oil and a large amount of carbohydrates. Walnuts contain a large proportion of protein and fat, but are quite indigestible. The cocoanut contains a large amount of fat and car- bohydrates. FUNGI, ALGAE, AND LICHENS. Fungi.-The three varieties of fungi usually eaten are the mushroom, truffle, and morel. Mushrooms are prized chiefly for their agreeable taste. They possess some nutritive value. Gibson, who has made a study of edible fungi, considers that the usual methods of distinguishing between the edible and poison- ous varieties are very unreliable. He suggests the fol- lowing as being of especial value: First, avoid every mushroom having a cup or suggestion of such at the base; the distinctly fatal poisons are thus excluded. Exclude those having an unpleasant odor, a peppery, bitter, or other unpalatable flavor, and those of tough consistency. In addition, it is well to exclude those VEGETABLE FOODS. 81 infected with worms, those in advanced age, or partly decayed, and in testing new species they should be kept apart from the others. The best test is to begin with a piece the size of a small pea, chew it very slightly, being careful not to swallow any of the saliva, and finally expel all from the mouth. If no results follow during the interval of a day the experiment may be repeated, swallowing a little of the juice, the fragments of the fungus being expelled as before. In twenty-four hours the third trial may be made, swallowing a small fragment, and if still no unpleasant results follow, the following day a piece the size of a hazel nut may be attempted. In using this method poisonous varieties may be excluded with only a temporary indisposition on the part of the experimentalist, and is the only safe method of avoiding the poisonous varieties. As a rule, any mushroom, omit- ting the Amanita, which is pleasant to taste and agree- able as to odor when raw, is probably harmless, and, if an unfamiliar species, may be tested by the above method. The truffle grows underground and is especially sought for on account of its delicate flavor; the black variety is considered the finest. The morel is usually obtained from France. It is sold in the dried state and is utilized chiefly for seasoning purposes. Many fungi are poisonous, and these are usually dis- tinguished by a disagreeable odor and taste, and other peculiarities in structure, etc. Algae.-The only one of this group that is utilized as food is Irish moss. I/icheiis.-The only important lichen used as a food is Iceland moss. 82 DIETETICS FOR NURSES.

Sugars are carbohydrates that contain hydrogen and oxygen in a proportion to form water. Sugar is one of the most valuable and popular forms of food. This popularity is due not only to its nutritive value, but also to its pleasant taste. According to Abel, 86 pounds of sugar per capita were consumed in England in 1895 and 64 pounds in the United States in the same year. From 7,000,000 to 8,000,000 tons are consumed annually in the different countries of the world. The principal variety of sugar in use is cane-sugar; besides this, grape-sugar, fruit-sugar, and milk-sugar also enter into the composition of our foods. Sugar is obtained in a fluid state, as in honey, as well as in crystalline form. Sugar is very fattening and at the same time is also a great source of muscular energy. Most of the ill effects attributed to the use of sugar are due to the fact that more than one-quarter of a pound is consumed daily (Hutchison); this amount maybe taken with impunity by the healthy adult, but if more be taken, it will be excreted rapidly by the kidneys, giving rise to a condi- tion known as temporary or alimentary glycosuria. Sugar can be absorbed only as dextrose and as levu- lose, all varieties of sugar being converted into these forms before they are absorbed. In strong solution sugar irritates the mucous membrane of the stomach and is apt to undergo fermentation, and thus produce gastro-intestinal distress. Cane-sugar is the most common and most exten- sively used form of sugar. It is made chiefly from sugar-cane and from the sugar-beet. When pure, it consists of a mass of white crystals. Candy contains a large amount of sugar, besides but- SUGARS. VEGETABLE FOODS. 85 ter and other fats, starch, nuts, flavoring extracts, etc. The chief varieties of candy are made up largely of glucose and starch, colored with anilin dyes. Molasses, Treacle, and. Syrup.-Molasses and treacle are by-products formed in the manufacture of cane-sugar. Molasses forms a highly nutritious food. On account of the impurities it contains, molasses has a more pronounced aperient effect than refined syrup. Glucose, or grape-sugar, is chiefly made from starch by inversion or hydrolysis. It is not nearly so sweet as cane-sugar and crystallizes with difficulty. It is present in small quantities, in combination with other varieties of sugar, in most fruits. Lactose, or sugar of milk, is the natural carbo- hydrate for the young, growing infant. It is less abun- dant in cows' milk than in human milk. Honey is sugar in a concentrated solution. It is made by bees from the nectar gathered from various flowers. It contains a crystallizable sugar resembling glucose, and a non-crystallizable form. Saccharin is used largely as a substitute for sugar in cases of rheumatism and diabetes. Levulose, or fruit-sugar, is also utilized as a form of sugar in certain cases of diabetes. SPICES AND CONDIMENTS, Spices and condiments play an important role in increasing the appetite and aiding the digestive func- tions ; they have practically no nutritive value. By the action of these substances on the organ of taste as well as on the mucous membrane of the stomach, the appetite is stimulated and the secretion of gastric juice increased. In certain gastric disturbances, as well as in diseases of the kidneys, they act as irritants and should be avoided. 86 DIETETICS FOR NURSES. The peppers are among the favorite spices; there are two varieties, the white and the black. Mustard.-Mustard is used chiefly in salads or with other foods, and has a marked tendency to increase the appetite. In large quantities and diluted with water mus- tard acts as an irritant to the stomach, producing nausea and vomiting. Vinegar is produced from various alcoholic drinks and from fruits. It contains 5 per cent, of acetic acid. Horseradish, is a condiment that is much used with various foods. Sauces, such as tomato, catsup, Worcestershire, and the like, increase the appetite and give a relish to certain foods. Spices act merely by adding a flavor to foods, in this way increasing the appetite for foods that would other- wise be insipid. Those most in use are ginger, cinnamon, nutmeg, and cloves. FATS AND OILS. One-fifth of the body-weight consists of fat. This is obtained in part from fatty food and in part from the car- bohydrates and the proteins. Most of the heat energy furnished the body is supplied by fat; it oxidizes very rapidly, and in this way spares the protein elements that would otherwise be required to furnish energy. Fats are digested in the intestine, where they are emul- sified previous to being absorbed. The most useful forms of fat are cream and butter; other forms are bacon and cod-liver oil. When eaten too liberally, fats are liable to cause indigestion, and when this exists they should be taken only in very restricted quantities. Foods fried in fats are indigestible, and hot fats are more indigestible than cold. Fats and oils have a ten- VEGETABLE FOODS. 87 dency to relieve constipation, but are contra-indicated in diarrhea. The most important animal fats are butter, cream, lard, suet, oleomargarin, cottolene, butterine, cod-liver oil, and bone-marrow. Of the vegetable fats, those most com- monly employed are olive oil, cottonseed oil, linseed oil, cocoa-butter, and the oils obtained from nuts, such as cocoanut oil, peanut oil, and almond oil. Fatty foods are indicated especially in wasting disorders and in con- valescence from certain acute diseases. There are many proprietary fatty foods on the market, some of which are worthy of mention. In most of these the fats, usually cod-liver oil, have been emulsified ; this emulsification aims to make the oil less objection- able to the taste and also to render it more easily diges- tible. Intolerance to Fat.-Intolerance to fat is frequently noted in infants and also in older individuals. In infants it may produce vomiting one or two hours after feeding, or there may be colic and either large white stools, or, less fre- quently, thin, greenish ones. Sooner or later there is a marked disturbance of the general health, and the children are usually, though not always, pale and thin. Many such children are given large quantities of fatty food, cream, butter, and oil, with the idea of fattening them up, with the result that the children's general health is very markedly interfered with. Butterine is a fat prepared from beef and hog fats, and is frequently used in this country instead of butter; oleomargarin is a similar preparation made from beef fat. Both butterine and oleomargarin are wholesome fatty foods, the only objection raised against them being that they are often sold fraudulently for butter. Bone-marrow is a fat obtained from the large bones of 88 DIETETICS FOR NURSES. the ox. It is used in the treatment of tuberculosis and in the various forms of anemia. SALTS. The various salts that enter into the composition of the tissues of the body are absolutely necessary for the maintenance of life. The most important, and by far that most universally found, is sodium chlorid, or com- mon table salt. It enters into the formation of all the tissues and secretions of the body with the exception of the enamel of the teeth. It forms about 60 per cent, of the salts of the blood. When taken in insufficient quanti- ties or omitted entirely marked symptoms of malnutrition soon appear. Potassium chlorid ranks next in importance to sodium chlorid. It is widely distributed in the body, but occurs in much smaller amounts. Calcium salts are important chiefly on account of the extent to which they enter into the composition of the bones and the teeth. Phosphorus occurs in the muscles, bones, and blood. It is found as phosphate in both animal and vegetable food. The sulphur of the body is derived from egg albu- min, milk, and certain vegetables, in which it occurs as sulphates. Iron is an important constituent of the hemoglobin of the blood, and is found also in muscle-fibers. BEVERAGES AND STIMULANTS. WATER. Water is the chief constituent of all beverages, and also enters largely into the composition of solid food. The human body itself is composed of about 60 per BEVERAGES AND STIMULANTS. 89 cent, of water. While man can live for weeks without food, he can abstain from water for but a few days. Water is absolutely necessary as a solvent, and as it is constantly being eliminated by the skin, lungs, and kid- neys, this loss must be replaced by some means in order to maintain the functions of the body. This is most conveniently done through the agency of the various beverages. The best method, however, of replenishing the water-supply is that of drinking the water in its pure state, when it retains all its solvent properties. Some waters are taken for their laxative or purgative action, and others for the salts which they contain. The amount of water consumed daily by the average person is from six to eight glasses. This varies, how- ever, with the amount and variety of food and exercise taken. The age, sex, and size of the individual and the season of the year also influence the total daily consump- tion of water. In very warm weather, for example, and under severe physical strain, much water that would not be lost in the cold season of the year is eliminated in the form of perspiration and must be compensated for. Water is absorbed chiefly in the intestine; a small amount is absorbed in the stomach, and but a very trifling amount, if any, in the mouth. The water ab- sorbed in the intestine is passed into the lymphatics and carried on into the circulation, whence it is eliminated. As previously stated, water is eliminated through the skin, kidneys, lungs, and feces. The amount of water excreted daily varies greatly under special conditions. In cold weather the skin is inactive and the kidneys excrete a markedly greater amount of water than in hot weather, when the sweat-glands functionate more actively. When there is a tendency toward liquid movements from 90 DIETETICS FOR NURSES. the bowel, the elimination by the kidneys is lessened. In warm weather elimination by the lungs is stimu- lated. According to the amount of mineral water they con- tain, waters are classed as hard or soft. Rain-water is soft, and is the purest form of natural water. The hard- ness of water is due to earthy carbonates; by boiling, the carbonic acid gas is driven off and the carbonates are precipitated, and the water thus rendered more suitable as a beverage. Boiling has the additional advantage that it destroys most of the micro-organisms that may be present in the water. Water often contains impurities, such as lime, mag- nesia, iron, and other salts, and micro-organisms, and it often becomes necessary to purify it for drinking pur- poses. Typhoid fever and cholera are communicated chiefly through the agency of polluted drinking-water. The best method of purification is by distillation, by which means both organic and inorganic impurities can be removed or rendered innocuous. This method is now used largely on shipboard. When distilled and aerated, sea-water makes a most pleasant beverage. Water may also be purified by means of filtration, char- coal and sand being used extensively for this purpose. Porcelain cylinders are also in common use. Whatever the filtering agent employed, unless it be kept clean it is liable to become a source of contamination rather than of purification. Owing to the fact that soluble impuri- ties often pass through the filter, filtered water is not nearly so reliable as distilled water. Mineral Waters.-Mineral waters are frequently taken as substitutes for ordinary water; at times they produce a most marked stimulating effect on various BEVERAGES AND STIMULANTS. 91 organs. Their efficiency is greatly enhanced when a " drinking cure " is combined with proper dietetic regu- lations. Mineral waters differ from ordinary waters in the greater amount of gaseous and solid matters they contain. The gaseous constituents of mineral waters are mainly carbon dioxid and sulphuretted hydrogen. The solid constituents are salts of sodium, potassium, magnesium, aluminium and calcium, iron, iodin, bromin, chlorin and sulphur. Taken before meals, waters con- taining carbonic acid have a soothing effect on an irri- tated stomach. Taken in excess, all carbonated waters are apt to produce indigestion. Some waters have a purgative effect, others a laxa- tive, and still others a diuretic. Thermal waters issue hot from their springs, their virtue being said to be due to their heat. Some mineral waters have no medicinal vir- tue whatever, and are utilized merely as drinking-water. The following classification of mineral waters is taken from Cohen's Physiologic Therapeutics, Vol. IX.: Simple acidulous contains large amounts of car- bon dioxid ; example, Apollinaris. Alkaline acidulous contains large amounts of car- bon dioxid and also sodium carbonate; example, Saratoga Vichy. Alkaline muriated acidulous contains carbon di oxid, sodium carbonate, and sodium chlorid ; exam- ple, Seltzer. Alkaline saline acidulous contains sulphate of soda in addition to bicarbonate and chlorid of soda, as Carlsbad water. I. Alkaline mineral waters. II. Sodium chlo- rid waters. Simple sodium chlorid contains sodium chlorid and carbon dioxid, as Saratoga Congress. Sodium chlorid with iodin and bromin contains iodin and bromin in addition to sodium chlorid, as Saratoga Kissingen. 92 DIETETICS FOR NURSES. HI. Bitter waters contain a large proportion of sodium sulphate and magnesia sulphate, as Bedford Magnesia water. IV. Sulphurous waters contain hydrogen sulphid or some other sulphur compound, as French Lick Spring. Carbonated iron-waters contain larger quantities of carbonic acid, as Cresson Spring water. Sulphated iron-waters contain ferrous sulphate in addition to sodium magnesia, and calcium sulphate, as Sharon Chalybeate Spring. Iron-and-arsenic-water contains arsenic and iron, as Harbin Hot Sulphur Spring. V. Iron-waters. VI. Earthy mineral waters contain large amounts of calcium and mag- nesium salts, as Mount Clemens Mineral Springs. VII. Acratothermal waters do not contain any active mineral ingredients, but are obtained at a temperature of 85° F. or over. TEA. Tea is a preparation made from the leaves of an ever- green plant known as thea. It is grown in China Japan, India, Ceylon, and in North Carolina. There are two great classes of tea, the green and the black. The chief difference between the black and the green tea lies in the fact that black tea is fermented, while green is not. As in the process of fermentation the tannic acid becomes less soluble, black tea contains much less tannic acid than green tea. Tea has practically no nutrient ingredients. Its prin- cipal constituents are caffein and tannic acid, and its special aroma is due to a volatile oil. It owes its stim- ulating effect to the presence of caffein. As the action of tannic acid is detrimental to the process of digestion, tea should be so prepared as to contain as large a pro- portion of caffein as possible and the smallest possible amount of tannic acid. When the leaves are placed in boiling water, caffein is extracted very rapidly. Tannic acid, however, is much less soluble; it follows, therefore, that in order to have BEVERAGES AND STIMULANTS. 93 as little tannic acid in the tea as possible, the leaves should be boiled in water for as short a time as practicable. To prepare the infusion, pour boiling water on the tea-leaves and allow the mixture to stand where it will keep hot, though not boil, for from three to five minutes. The water used in preparing tea should not be hard or stale. Coffee was introduced into Europe in the same century as tea, and only a few years later. It is prepared from the seeds of Coffea arabica, which was originally grown in Arabia. The aroma of coffee is due to the presence of caffeol, an oil liberated in roasting. Coffee is often adulterated, chicory, acorns, and other substances being added for this purpose. The adulteration may not be injurious in its effect, but alters sometimes, even agree- ably, the flavor of the coffee. Preparation of Coffee.-In order to obtain coffee of the finest flavor, the beans should be roasted and ground shortly before they are to be used, as the flavor is impaired by exposure to the air after grinding. The water should have reached the boiling-point before it is poured over the coffee. The pot should then be placed for a few moments in a hot place, but boiling must not be allowed to continue, or the aroma will be lost and the coffee contain too large a percentage of tannic acid. The effect of coffee on the system is that of a stim- ulant, due to the caffein present; it acts directly on the brain centers, stimulates the heart, and deepens the res- pirations. It is an excitant of the nervous system, and in some persons produces nervousness, excitability, and insomnia; in others it acts as an agreeable stimulant. Coffee Substitutes and Modified Coffees.-Vari- ous substances are used as substitutes, usually chicory COFFEE. 94 DIETETICS FOR NURSES. or roasted grains. Most of the so-called caffein-free coffee preparations either do not contain coffee or contain caffein in rather large amounts. Kaffee Hag contains only 0.03 per cent, caffein and DeKofa about 0.13 per cent. COCOA. Cocoa was introduced into Europe long before either coffee or tea. It is prepared from the seeds of the cacao tree. The seeds are contained in a pulpy fruit, some- what resembling a cucumber, from which they are extracted. Cocoa, as ordinarily prepared, is made by grinding the seeds into a paste, to which sugar or starch is added ; if starch is used, the cocoa is boiled for a few minutes, but if sugar is added, the cocoa only requires the addition of boiling water or milk. Cocoa, while a stimulant, is less apt to induce nervous symptoms, such as sleeplessness and palpitation, than either tea or coffee. By reason of the large proportion of sugar and fat contained in it, however, when used in excess, cocoa is likely to produce indigestion. When not too rich, it forms a nutritious drink especially useful for children and for convalescents. Chocolate is prepared by adding starch, sugar, and such flavoring substance as vanilla to cocoa. In addi- tion to their stimulant effect, cocoa and chocolate pos- sess a marked nutrient value not possessed by either tea or coffee. ALCOHOL. Alcohol is produced by the fermentation of sugars with yeast. The principal constituent in all alcoholic beverages is ethyl alcohol. The glucose contained in fruits is fermented directly into alcohol; whereas the starches in such substances as potatoes, grains, etc., are BEVERAGES AND STIMULANTS. 95 converted into dextrin and maltose, and then by the aid of diastatic ferments, before the alcoholic fermentation can take place, they are converted into glucose. The food value of alcohol has been a subject for discussion for many years. Although all admit that alcohol taken in excess is a poison and is detrimental to health, yet opinions differ widely as to the food value of alcohol taken in moderate quantities. There are those who maintain that alcohol, even in small quantities, is detrimental to health and acts as a poison; whereas others believe that, on the contrary, when taken in small quantities it possesses a considerable nutrient value and is to be recommended as a valuable food. The most recent as well as the most exhaustive work bearing on this subject has been done by Atwater, in his experiments on " The Nutritive Value of Alcohol," in The Physio- logic Aspects of the Liquor Question, 1903. According to the writer the effect of alcohol in small quantities is slightly to increase the digestibility of protein, but not to alter the digestibility of other nutrients-that is, carbo- hydrates and fats; that at least 98 per cent, of the alco- hol ingested is oxidized in the body, whereas ordinarily 98 per cent, of the carbohydrates, 95 per cent, of the fats, and 93 per cent, of the protein are oxidized; the alcohol is therefore oxidized more completely than are the nutrients of ordinary foods. The conclusion reached by Atwater, based on direct experiments, is that the fat protection following the use of alcohol is very slightly different from that following the taking of ordinary food, and that alcohol protects the body-fat quite as effectively as do the fats and carbo- hydrates of the food for which it is substituted. The power of alcohol to protect the protein of food or body- tissue, or both, from consumption is clearly demonstrated. 96 DIETETICS FOR NURSES. Alcohol, carbohydrates, and fats replace one another as sources of energy, so that as one is oxidized the other is correspondingly spared. Atwater found that in most of the experiments "alco- hol was certainly a source of heat for the body " and contributed its share of energy for muscular work. Atwater gives the following proportions as to the availability and fuel value of alcohol in nutrition as com- pared with carbohydrates and fats: I gm. of alcohol, if gm. of carbohydrate, and f gm. of fat yield the same amount of energy to the body. Inasmuch as alcohol contains no nitrogenous constituents, it can not be looked upon as a food tending to repair tissue, but merely as a fuel that, on oxidizing, forms animal heat. Alcohol is easily digested and readily absorbed in the alimentary tract; as a food, however, it is costly, and the danger of addiction and excess in its use is great. The habitual use of alcohol even in considerable quanti- ties does not tend to produce injurious effects in many persons; whereas in others changes, especially of a cirrhotic nature, in the tissues, blood-vessels, liver, kid- neys, etc., are liable to occur. In certain diseases, especially those accompanied by malnutrition, extreme feebleness, and exhaustion, alcohol acts as a food and serves an excellent purpose in restoring strength to a weak and enfeebled body. Alcoholic beverages are divided into several classes, S'> spirits, liqueurs, and bitters, malt liquors, wines, etc- SPIRITS. Spirits are produced by fermenting saccharine sub- stances and obtaining the alcohol by distillation. Of the substances, corn, rice, barley, molasses, and potatoes are those most commonly utilized for this purpose. In BEVERAGES AND STIMULANTS. 97 addition to the alcohol, by-products are formed, and it is to these that spirits owe their characteristic flavor and odor. The by-products contain the higher alcohols, such as propyl, butyl, and amyl alcohol, a mixture of these forming what is known as fusel oil. Whisky is an alcoholic liquid obtained by distilla- tion of the mash of fermented grain (usually of mix- tures of corn, wheat, and rye), and at least two years old. Whisky possesses an alcoholic strength of from 50 to 58 per cent, by volume. It should be free from disagreeable odor. The ether and aldehyds contained in whisky become altered in character as it ages, and the flavor is thus rendered more agreeable. Brandy is an alcoholic liquid obtained by distillation of the fermented unmodified juice of fresh grapes, and at least four years old. Brandy contains from 46 to 55 per cent, by volume of alcohol. The quality of brandy depends upon the variety of grapes used and upon the length of time the brandy is allowed to stand: the older the brandy the better the quality. With brandy, just as with whisky, on standing ethers and aldehyds are produced, to which the special flavor of the brandy is due. The color of brandy is due to the tannic acid extracted from the oak casks in which the brandy is contained. There are many inferior grades of brandy on the market, some being merely alcohol colored and flavored with various essences. Rum.-Rum is the product of the distillation of fer- mented molasses, its flavor being due to certain by- products. Gin.-Gin is produced by the distillation of rye and malt mash, its flavor being due to juniper berries which are added during fermentation. IJqueurs or cordials and bitters contain a large 98 DIETETICS FOR NURSES. proportion of alcohol and a high percentage of sugar and essential oils. Malt I/iquors.-Under the heading of malt liquors are included beer or ale and stout or porter. These beverages are made by fermenting malt and hops. The mild or bitter beers are distinguished by the relative pro- portion of hops contained in them; the milder forms contain considerable quantities of hops, whereas the bit- ter ones contain but small amounts. Porter and Stout.-Porter and stout are made by fermenting malt, the latter, however, being roasted, dur- ing which process a certain amount of caramel is pro- duced. It is to this substance that the dark color is due. Beer as well as stout contains from 3 to 8 per cent, of alcohol, from 2 to 5 per cent, of dextrin, and from 0.5 to 1 per cent, of sugar. WINE. Wine is produced by the fermentation of grape-juice, the juice being first pressed from the grape by crushing. There are a number of factors, such as the character of the grape utilized, its cultivation, and the method of manufacturing, that enter into the production of a good wine. Of the important ingredients of wine may be men- tioned water, acids, alcohol, sugar, ethers, glycerin, and extractives. Acids.-The most important acids contained in wine are tartaric, malic, and tannic; others of less impor- tance are acetic and succinic. The total amount of acids in wine varies, but rarely exceeds 0.5 per cent. Alcohol.-There are several alcohols present in wine; ethyl alcohol occurs in largest quantity; amyl, propyl, BEVERAGES AND STIMULANTS. 99 and butyl alcohol are also present in varying amounts ; natural wine never contains more than 16 per cent, of alcohol; if it contains more than this amount it has been " fortified." This is often done, especially when the wine is to be shipped from warm countries to foreign districts, to prevent it souring. Sugar.-Sour wines contain about I per cent, and sweet wines about 4 per cent, of sugar; it is evident, therefore, that sugar is present in too small a quantity to be of any food value. Ethers.-Many varieties of ethers are present in wine; they are produced by the action of the alcohols and acids upon each other. It is to the character and quantity of the ethers contained in them that the flavor of various kinds of wines is largely due. Glycerin.-Glycerin is present in wine in about one- fourteenth of the volume of the alcohol. Extractives.-A large part of the solid material of the wine is made up of extractives. Varieties Of wines.-From a dietetic standpoint the classification of Chambers is probably the most practi- cal ; according to this author, wines are divided into seven classes: 1. Strong dry wines. 2. Strong sweet wines. 3. Aromatic wines. 4. Acid wines. 5. Spark- ling wines. 6. Perfect wines. 7. Rough or astringent wines. 1. Strong Dry Wines.-These are wines that contain a large percentage of alcohol, to which, as a rule, addi- tional alcohol has been added in their production; in other words, they are "fortified." Examples of this class of wines are port, sherry, and Madeira. Port con- tains from 15 to 20 per cent, of alcohol and considerable 100 DIETETICS FOR NURSES. tannic acid. Sherry is a fortified wine ; it contains from 15 to 22 per cent, of alcohol. 2. Strong Sweet Wines.-These wines contain fruit- sugar in quantities sufficient to act as a preservative and prevent further fermentation. Under this head may be mentioned Tokay, Malaga, and sweet champagne. They contain from 18 to 22 per cent, of alcohol and from 3 to 5 per cent, of sugar. Owing to their sweetness they are taken in small quantities. 3. Aromatic Wines.-Aromatic wines possess a superior flavor and contain essential oils and considerable alcohol; examples of this class of wines are Moselle, Capri, and some of the Rhine wines. 4. Acid Wines.-The distinguishing feature of this class of wines is the large quantity of acid they contain. 5. Sparkling Wines.-Sparkling wines contain consid- erable quantities of carbonic acid gas, to which their exhilarating effect is due. The chief variety of this class of wines is champagne. The dryness or sweetness of champagne depends upon the proportion of cane-sugar and cognac added during the process of manufacture. In the manufacture of dry champagne 8 per cent, of sugar is added, while the sweet brands contain as much as 16 per cent. 6. Perfect Wines.-Perfect wines are defined by Cham- bers as those containing alcohol, water, sugar, ethereal flavors, fruity extractives, and acids. Under this head come Burgundy and Bordeaux. 7. Rough Wines.-Rough wines contain considerable quantities of tannic acid, to which they owe their astrin- gent effect. They contain little alcohol and are of slight value for medicinal purposes. BEVERAGES AND STIMULANTS. 101 ACTION AND USE OF MALT LIQUORS AND WINES. Malt liquors, when taken in moderate quantities, seem to aid digestion, increase the appetite, and stimulate gas- tric secretion. Occasionally, especially in those who lead a sedentary life, they give rise to indigestion and gastric acidity. On account of the large quantities of carbohydrates they contain, they have considerable food value. The use of malt liquors is contra-indicated espe- cially in such conditions as gout, obesity, diabetes, and diseases of the urinary tract. Wines appear to exert a depressing effect on the gas- tric secretion. Taken in moderate quantities, however, by increasing the appetite and the motor function of the stomach, this depressing effect is not only overcome, but the digestion is also greatly improved. Cider is a beverage prepared from the'fermented juice of ripe apples. The amount of alcohol contained in this beverage varies between 3 and 8 per cent, by volume. It also contains malic acid, salts, sugar, albuminoids, and extractives. CHAPTER III VARIOUS FACTORS IN THEIR BEARING ON DIET. CONCENTRATION OF FOOD. Concentrated foods are those from which the larger portion of the water present has been abstracted, and thus the weight and the bulk of the food diminished. There are many patented concentrated foods on the market. They find their chief use in the treatment of patients who take too little of the usual forms of food to maintain strength, and, second, in cases where it is impor- tant that a large quantity of nourishment be taken. Food can be concentrated to various degrees. Desic- cated meat is the most concentrated form of protein; sugar the most concentrated form of carbohydrate; and olive oil the most concentrated form of fat. i. Concentrated Proteins.-These foods are pre- pared from milk, meat, eggs, and vegetables. Meat is concentrated by drying, and in this form it is generally indigestible, which can, however, be overcome by pre- digestion or powdering. 2. Concentrated Vegetables.-Many vegetables, such as potatoes, carrots, cabbage, and the like, are con- centrated by drying. They are utilized only in those in- stances in which it is impossible to secure fresh vegetables. Bread is frequently dried and eaten in the form of " hardtack," when it is impossible, as during sea-voyages, to obtain fresh bread. 102 VARIOUS FACTORS IN THEIR BEARING ON DIET. 103 PRESERVATION OF FOOD. By preservation of food is meant the process by which the food is so changed that it can be kept for a longer or shorter period of time without undergoing putrefaction. The process of fermentation is induced by micro-organ- isms present in the atmosphere coming into contact with the food and contaminating it. Since putrefactive germs require a certain amount of moisture and heat for their growth, such foods as contain little water and that are not kept too warm are not so likely to undergo decomposi- tion ; on the other hand, foods containing much water undergo fermentation very rapidly. To prevent this proc- ess, four methods of preservation are, according to Yeo, available : I. Drying. 2. Exclusion of air. 3. Exposure to cold. 4. Treatment with antiseptic chemic agents. 1. Drying.-By this process a large proportion of the water is abstracted. Vegetables, such as carrots, peas, potatoes, etc., are preserved by drying. Milk, in the form of nutrose, eggs, as egg-powder, and fruits are often preserved in this manner. 2. Exclusion of Air.-Air may be prevented from coming into contact with food in a number of ways : by immersing the food in oil or fat; by heating the food, so as to evaporate the external layers; by coating with some impermeable substance, as oil, salt, sawdust, var- nish, or paraffin. Fish are frequently preserved by im- mersion in oil or by smoking. Ham and bacon are pre- served by smoking, by which process the outer surface becomes coagulated and impermeable. Eggs are pre- 104 DIETETICS FOR NURSES. served by covering the fresh eggs with some imperme- able substance, such as oil, fat, beeswax, or sawdust. In order properly to preserve food by exclusion of air, it is highly important that the food be perfectly fresh, and that any air that may be present be expelled. In canning, the food to be preserved is heated in tin cans until steamed, when, all the air having been expelled, the can is soldered and rendered air-tight. 3. Exposure to Cold.-Food can be preserved in- definitely by ice. Meat and fish, which are often pre- served by this means, should be cooked at once after thawing. Frozen meat loses about 10 per cent, more of its nutritive value in cooking than fresh meat. Frequently food is not kept directly on ice, but in refrigerating cham- bers. 4. Treatment with Antiseptic Chemic Agents.- 1. Salting.-The salting of food is a method that has been practised for many centuries. In this way meat and fish are easily preserved. The pale color of the meat produced by salting is overcome by adding a little saltpeter in addition to common salt. After the salting has been accomplished, it is often followed by smoking. 2. Sugar in strong solution acts as an antiseptic, and fruits are thus often preserved in concentrated syrups. 3. Vinegar acts as an antiseptic in preserving cucum- bers, pickles, oysters, etc. 4. Other Antiseptics for Preserving Foods.-Among these substances are sulphur vapor; weak carbolic acid ; strong acetic acid; injections of alum and aluminium chlorid into the blood-vessels; boric acid; borax; sali- cylic acid; formaldehyd. The use of antiseptics to preserve foods is usually condemned, and laws have been enacted to prevent the VARIOUS FACTORS IN THEIR BEARING ON DIET. 105 adulteration of such foods as milk, beer, etc., with anti- septics, as salicylic acid, formaldehyd, etc. While small quantities of these substances, even taken for a consider- able length of time, may not prove injurious, in large quantities they are dangerous. ARTIFICIAL FOOD PREPARATIONS. To this class of foods belong those preparations that are so concentrated as to furnish a large amount of food in small bulk; being of small bulk, they can be added to liquid foods, and thus the nutritive value of the latter increased without increasing the total quantity of liquid taken. A number of these preparations have been men- tioned under the head of beef-juices and meat-powders. The various casein preparations, among which may be mentioned nutrose, eucasein, sanose, and plasmon, are artificial foods. Among other artificial food preparations may be men- tioned: i. Pemmican. 2. Peptone products. 3. Mosquera " Beef Meal." 4. Somatose. 5. Legumin. 6. Aleuronat. 1. Pemtnican is prepared by cutting meat into thin slices and allowing them to dry; sugar and dried fruits are added, the nutritive value of the meat being thereby increased. 2. Peptone products are predigested protein foods. When given in large quantities they tend to produce diarrhea, and are objectionable to many patients on account of their disagreeable taste. Among the principal peptone products manufactured may be mentioned Kemmerich's, Koch's, Benger's, Savory & Moore's, Carnrick's, Ar- mour's Wine of Beef Peptone, and Panopeptone. 3. Mosquera Beef Meal is prepared by partially digesting meat by means of a ferment obtained from 106 DIETETICS FOR NURSES. pineapple juice. According to Chittenden, this product contains 90 per cent, of nutritive matter (13 per cent, of fat and 77 per cent, of protein). 4. Somatose is a predigested meat consisting of albu- moses. It is a yellowish powder, tasteless, odorless, and highly nutritious, and is usually well borne even in gas- tric disturbances. 5. I/egumin consists of the casein of the legumes, and is a highly nutritious protein food. 6. Aleuronat is a brownish powder, chiefly utilized as a food for diabetics. It contains 80 per cent, of protein. 7. Tropon is prepared mainly from fish and vegeta- bles, and as sold on the market appears as a brownish, tasteless powder. It is eaten mixed with broths or gruels. Artificial Proprietary Foods.-A large number of proprietary foods designed as substitutes for milk for infants and invalids are on the market. Infants fed upon such foods alone are apt to become rachitic. Some of these foods have little food value; especially the amyla- ceous foods in which the starch has not been predigested. Many of these preparations contain too little fat and far too great a proportion of carbohydrates. According to Holt, " when children are fed upon foods lacking in fat the teeth come late, the bones are soft, the muscles flabby," while " children fed upon foods containing too much sugar are frequently very fat, but their flesh is very soft; they walk late and they perspire readily about the head and neck." Hutchinson divides proprietary foods into three classes : I. Foods Prepared from Cows' Milk with Various Ad- ditions or Alterations, and Requiring only the Addition of Water to Fit Them for Immediate Use.-To this class VARIOUS FACTORS IN THEIR BEARING ON DIET. 107 belong Malted Milk, Nestle's Food, Lactated Food, Carn- rick's Food, Cereal Milk, Wyeth's Prepared Food, and Wampole's Milk Food. These foods are prepared from flour baked and mixed with milk or cream and then dried. By means of the malt which is added the starches are converted into dextrin and maltose. 2. Farinaceous Foods Prepared from Cereals of which the Starch has been Partly or Wholly Converted into Dex- trin or Sugar, and which Require the Addition of Milk to Fit Them for Use.-To this class belong Mellin's Food, Savory & Moore's Infant Food, and Benger's Food. These foods are prepared by mixing equal parts of wheat flour and barley malt with bran and potassium bicarbon- ate. The mixture is made into a paste with water, and kept at a warm temperature until the starch is converted into dextrin and maltose. As these foods are poor in fat, protein, and mineral matters, they are added to milk in order to render them more nutritious. 3. Farinaceous Foods in which the Starch has not been Predigested.-To this class belong Ridge's Food, Neave's Food, Imperial Granum, and Robinson's Patent Barley. These foods are poor in fat, protein, and mineral mat- ters. Other Proprietary Foods.-Crackers are prepared from flour, water or milk, and are baked into various forms. Baking-powder and soda, and frequently milk, butter, sugar, and flavoring extracts are added. Crackers are, as a rule, easily digested. Malt Extracts.-Malt extracts are manufactured by heating a solution of malted barley at a moderate tem- perature in vacuo. Malt extracts are especially useful as beverages for those weakened by chronic disease, as tuberculosis or anemia, and in the convalescence from 108 DIETETICS FOR NURSES. acute diseases, as after typhoid fever or pneumonia. Among the various malt preparations may be mentioned Maltine, Kepler's Extract of Malt, and Hoff's Malt Extract. COOKING OF FOODS. The cooking of food is an art practised by all races, savage as well as civilized. Food is cooked to improve its flavor, to soften it so that it can be masticated and more easily digested, and finally to destroy all parasites and disease germs that may be present in the raw food. By cooking certain flavors are developed, which by their savoriness increase the appetite and the taste for the food. Cooking, moreover, destroys the tough fibrous envelopes that surround many foods, thus permitting the food to be more easily acted upon by the various digestive fluids. Various parasitic organisms present in many foods are destroyed by cooking, and the food thus freed from one of its most dangerous elements. On cooking, the protein in food coagulates; under the influence of dry heat the starches are gradually converted into dextrin; whereas, under the influence of moist heat the granules gradually swell until they rupture their en- velopes. Sugars, by boiling, are changed gradually into caramel, which is the source of the odor frequently given off in the cooking of food. When fats are heated they undergo a change, with the production of free fatty acids which are often responsible for the odors that exist in the kitchen. Cooking of Meat.-Boiling.-In boiling meats the temperature of the water should not exceed the tempera- ture necessary for the coagulation of the proteins. In order that the meat may retain as much of its flavor as possible, it should be immersed in boiling water for a few VARIOUS FACTORS IN THEIR BEARING ON DIET. 109 moments; in this way the protein on the surface imme- diately coagulates, thus preventing the escape of the con- stituents and so retaining all the nutritive elements in the meat. After this has been accomplished, the temperature of the water may be lowered and the process of cooking continued. The broth which is so produced is thin and poor. If a rich, nutritious broth is desired, the meat should be cut into small pieces and placed in cold water, and the temperature gradually increased to 1500 F. In this way the nutritious elements of the meat pass out into the broth. Roasting.-In roasting, the meat is first exposed to a high temperature and afterward cooked slowly; thus, the outer layers coagulate at once, preventing escape of the juices. Roasting not only prevents evaporation of the flavors of meats, but by its effect on the extractives de- velops savory odors and flavors. Baking.-Baking much resembles roasting, except that by the latter process the heat is applied all around the meat instead of only to one side. Stewing.-For this purpose meat is cut into small pieces and placed in a small quantity of water. The water is heated slowly, but not allowed to boil; a certain amount of the nutritious substances thus passes into the water, which then becomes rich, and to which flavoring substances and vegetables are added. Inasmuch as the juice is eaten with the meat, none of the nutritious in- gredients is lost. Braising.-In this process the meat is placed in a small vessel and covered with a strong liquor of vegetable and animal juices; it is then heated, but not boiled. The tough fibers of the meat are thus loosened and made tender; the meat also becomes impregnated with vegeta- 110 DIETETICS FOR NURSES. bles and spices present in the juices, which enhance its flavor. Broiling.-Broiling and roasting are similar processes, except that in the former smaller portions are utilized; the process is thus more rapid, a large surface being ex- posed to the direct action of the heat. Frying.-In this process the meat is put into boiling fat, with which it becomes saturated; fatty acids are thus produced, which have a tendency to irritate the stomach and cause indigestion. Cooking- of Fish.-Fish may be boiled, broiled, baked, and fried. Boiled fish is most easily digested. Inasmuch as the flavoring substances are more easily dissolved out into the water and lost, less time should be consumed in boiling fish than in boiling meat. Sir Henry Thompson has shown that even with careful boiling 5 per cent, of the solid matter of fish is apt to be lost; for this reason steaming is often preferable. Effect of Cooking.-The effect of cooking on meat is to diminish its watery constituents, thus concentrating and rendering it more nutritious; by this process also the extractives as well as some of the fats are partly removed. Effect of Cooking on Vegetables.-The important object in the cooking of vegetables is to rupture the cellulose envelope and so to soften the contained starch granules. Under the influence of heat and moisture the starch swells and bursts its envelope, forming a paste; this paste, in its turn, expands and ruptures the cellulose envelope; cooking, therefore, renders vegetable foods more easily digestible. As has been pointed out, in the cooking of meats a certain proportion of the ingredients is lost. Unlike meats, however, vegetables become more watery in cook- VARIOUS FACTORS IN THEIR BEARING ON DIET. 111 ing. In this condition they are more easily acted upon by the gastric secretion; on the other hand, the addi- tion of water in cooking so increases their bulk that the motor function of the stomach is apt to be over- taxed. When food is cooked rapidly there is a tendency to overcook the outer layers and to leave the inner under- done. The better plan, therefore, is to cook food slowly for a longer period of time at a lower temperature. Various appliances are on the market which have for their object the production of a continuous action of a moderate heat at the expense of as little fuel as pos- sible. DISEASES CAUSED BY ERRORS IN DIET AND BY VARIOUS FOOD POISONS. Disease may be caused by taking too little or too much food, and also by a diet that is not well balanced- that is, does not contain the combination of food elements in the correct proportions-and by other dietetic influ- ences, the precise nature of which is as yet obscure. It may also be caused by certain poisons or disease germs or parasites taken into the body with food and drink. The diseases due to insufficient food are starvation, malnutrition, marasmus, and some forms of anemia. Chlorosis is liable to occur in underfed girls. Overeating probably causes as much disease as over- drinking. Among the most striking of these are gout and obesity. Diseases of the skin, kidneys, liver, and other organs may also be due to this cause. Lack of fresh food may produce scurvy and an im- properly balanced diet may cause rickets. The abuse of various beverages deserves mention. 112 DIETETICS FOR NURSES. The effects of the abuse of alcohol and the nervousness resulting from the excessive use of tea and coffee are well known. Food Allergy.-A subject that has been attracting a considerable amount of attention of recent years is the sensitiveness of certain individuals to various foods. This manifests itself after the ingestion of the offending food either in an outbreak of eczema or urticaria, of edema, or of asthma. It is very unusual to find in one individual idiosyncrasies to one food substance alone. In most cases there is a history of the same thing existing in other members of the family and it is very common to have the history of either eczema or asthma. Indi- viduals who are sensitive to food show skin reactions when small quantities of these foods are injected into the skin or rubbed into abrasions. In the cases that have been studied thoroughly the offending substance has been a protein, most commonly the white of eggs and the casein of milk, but other substances, as beef, pork, fish, clams, strawberries, and tomatoes, and so on, may furnish the substances causing the reaction. It seems highly probable that there may be a similar sen- sitiveness to fats and sugars, but this has not been definitely demonstrated. Persons having such sensi- tiveness may get better on withdrawing the toxic food, but this is not always the case. A very severe attack of poisoning may render the patient immune to attacks from the same substance for from two to three months, and it is possible to immunize the individual, certainly for some of the proteins, by giving first very minute quantities and gradually increasing the amount, but, as a rule, the individual does not retain his immunity unless he continues to take fairly large quantities of the food. This has been shown most frequently in the cases VARIOUS FACTORS IN THEIR BEARING ON DIET. 113 that are sensitive to eggs. Other terms are applied to this condition, such as "allergy" and "anaphylaxis." Acute food-poisoning is usually due to the action of ptomains, and this is called ptomain-poisoning. Pto- mains or toxins are poisonous substances caused by the action of bacteria, and may be generated in nitrog- enous foods or in the alimentary tract. They resemble alkaloids, and when absorbed are partially destroyed by the liver. The symptoms vary, but nausea, vomiting, purging, pain in the abdomen, and collapse are the most frequent. Various names are applied according to the food which causes the trouble, as milk-poisoning (galac- totoxismus) ; cheese-poisoning (tyrotoxismus); mussel- poisoning (mytilotoxismus); fish-poisoning (ichthyotoxis- mus); meat-poisoning (kreotoxismus). Faultily cured sausage sometimes causes poisoning (botulismus), and epidemics of pneumonia have resulted from eating in- fected bacon, infected ham, or other spoiled meat. The poison may be present without producing any change in the appearance of the meat. Some of these epidemics obviously are the result of epidemic pneumonia or en- cephalitis and are erroneously attributed to food-poison- ing. Other forms of food-poisoning are as follows: Mushroom-poisoning.-Poisonous fungi are frequently mistaken for edible mushrooms and lead to poisonous symptoms. The active principle in these fungi is called muscarin. If there is a ring about the stalk, the mush- room peels easily and has pink gills, it is said to be non- poisonous. This is not a safe rule, as some of the most poisonous varieties answer to this description. Grain-poisoning.-There are three forms of grain-poi- soning-ergotism, pellagra, and lathyrism. Most cases 114 DIETETICS FOR NURSES. and epidemics have occurred among the poverty-stricken European peasants. Ergotism (sitotoxismus) is due to eating spurred rye, from which the drug ergot is obtained. Lathyrism (lupinosis) is caused by eating the chick-pea. Beriberi.-This is a disease chiefly seen in the Orient, and it is supposed to be due to polished rice. The pol- ishing removes the outer cover, which contains a certain amount of phosphorus. The rice polishings mixed with milk and sugar are sometimes given as a cure. There are others who believe the disease is due to some parasite. At present it is thought that the absence of vitamins present in the pericarp is responsible. In institutions the disease may be prevented or cured, if not seen too late, by feeding the patient on bread made from whole wheat flour, or by the use of the brown, undermilled or so-called hygienic rice, beans, peas, and other legumes, barley, cornmeal made from the whole grain, white potatoes, and meat. Pellagra.-In the past few years there has been an enormous increase in the amount of pellagra in the United States. The cause of the disease is not as yet established. Some believe that it is due to a parasite transmitted by a certain two-winged fly, and others that it is due to eating certain foods, particularly maize which has been spoiled. More recent investigations place the blame on some vitamin deficiency and insufficient pro- tein. The disease may be prevented and cured by diets rich in animal and leguminous proteins, milk and fresh fruits, and vegetables. The latter should be with- held if there is diarrhea. Sprue.-This is a tropical disease associated with a monilia infection. Various dietetic methods of cure have been suggested. A diet free from carbohydrate, similar to a diabetic diet, seems to give good results. VARIOUS FACTORS IN THEIR BEARING ON DIET. 115 Milk diets, meat diets, and fruit and vegetable diets, and various combinations of these have all been recom- mended. Xerophthalmia in which there is dryness of the cornea with subsequent ulceration is due to a lack of fat-soluble A. It is seen sometimes in the last stages of marasmus and in adults who have received no animal fat, no milk, butter, or eggs. The addition of these to the diet effects a cure if the changes have not progressed too far. Cod-liver oil may also be used. Actinomycosis or lumpy-jaw, a disease of cattle, is some- times transmitted to man. In some of the cases the patients were in the habit of chewing raw grain. Foot-and-mouth disease is another disease of cattle which may be transmitted by the use of milk from cows suffering with it. Such milk should not be used. If the disease is suspected the milk should be boiled. Hydatid Disease.-Cysts of a peculiar character some- times occur in man by taking the eggs of a dog tape- worm (Taenia echinococcus) into the body with the food. Green salads are the most frequent source of infection. The disease is almost unknown in America. Idiosyncrasies.-Curious food idiosyncrasies exist and must be borne in mind. They are more often fancied than real. Urticaria (hives) may be caused in some people by eating crabs, oysters, strawberries, and other articles of food. Gastric pain, vomiting, diarrhea, and other symptoms may be produced by such foods in some per- sons, while others eat them with impunity. Parasites.-Certain parasites may be taken in with food or drink. Many of these are rare, and seldom if ever seen in America. Among them may be mentioned the following : Amoeba coli, taken in with drinking-water, is the cause of one form of dysentery. 116 DIETETICS FOR NURSES. Several species of tapeworm (Teenia solium in pork, T. mediocanellata in beef, etc.), of which the beef tape- worm is the common variety in the United States, may be met with. The pin-worm (Oxyuris vermicularis) and the round- worm (Ascaris lumbricoides), the eggs of which are sup- posed to be taken in water or raw food. The hook-worm (Strongylus duodenale), which causes a severe anemia, is taken in drinking-water. The trichina is taken in with raw pork, and the filaria is taken in with drinking-water. Infected Milk.-Certain diseases may sometimes be transmitted by infected milk. Among these are diarrheal diseases, diphtheria, scarlet fever, typhoid fever, and Asiatic cholera. The last two are usually carried by infected water. FOOD ADULTERATION. Food adulteration is of two kinds: that which is in- jurious and that which is non-injurious. The latter is practised where there are no fixed standards, or, where such do exist, in debasements from these fixed standards. Adulterations may be classified as follows: i. Conventional-to suit the taste and demands of the public. Such adulterations are usually effected by means of coloring-matters, many of which are harmful, and by bleaching certain products. 2. Accidental or incidental-arising from environ- ment, carelessness, or incompetency on the part of the producer, manufacturer, or his agents. This usually consists in an admixture of some foreign substance, such as husks, stems, leaves, etc. 3. Arbitrary-to comply with or take advantage of certain fixed arbitrary standards.

It may cause blindness or death. Lead and copper or white salts may occasionally find their way into canned food. This may be used intention- ally. Lead may come from solder dropped in the can or from using dull tin (terne or roofing-tin) for the cans. Only the bright tin should be permitted. Preservatives.-Various chemicals are mixed with foods to preserve them. In some countries the use of preservatives is forbidden. Borax, boric acid, salicylic acid, sulphate or bisulphate of sodium are the most fre- quent. They are all injurious, and if taken into the body continuously produce disturbances of digestion, lower the nutrition, and may cause disease of the kidneys. Formaldehyd is frequently used, and in general it may be stated that its use is undesirable and dangerous. Simple Tests for the Detection of Preserva- tives.-The following tests, largely adopted from Bigelow and Howard's article, will be found of use in detecting the more important commercial preservatives, with the VARIOUS FACTORS IN THEIR BEARING ON DIET. 119 exception of sulphites and fluorids. The sulphites are used in meats and the fluorids in fruits, and the methods for determining their presence are not suited for house- hold use. All of these tests require considerable expe- rience in order to draw correct conclusions. Salicylic Acid.-This is very commonly used in all kinds of foods, solids and liquids, especially fruit products. It is best detected in solution, and solids and semisolids should be macerated in water, and then strained through a white cotton cloth. Two or three ounces of the fluid to be tested is used, adding to it a few drops of sulphuric acid (or about 15 grains, the quarter of a teaspoonful, of cream of tartar). Shake thoroughly and filter. To the clear liquid add three or four tablespoonfuls of chloro- form, mix by a rotary motion, but do not shake, or an emulsion will be formed which is difficult to break up. Allow the chloroform to settle, and remove as much as possible by means of a pipette or medicine-dropper. This is placed in a test-tube, with an equal amount of water and a small piece-a little larger than a pin-head- of iron alum. Shake well and allow to settle, and if sali- cylic acid is present, the upper layer will have a purple color. Benzoic Acid.-This is used chiefly in fruit products, catsup, etc. This test is not sufficiently delicate for very small quantities, such as may be added to wine. Pro- ceed as above. Evaporate the chloroform by placing in a saucer outside of a closed window. In cold weather place the saucer in a basin of rather warm water. When the chloroform has evaporated the characteristic flat crystals of benzoic acid may be seen in the saucer, and on warming the characteristic irritating odor of the acid can be detected. 120 DIETETICS FOR NURSES. Borax and Boric Acid.-Both of these are used in many food products. Macerate solids or semisolids as above, cool the liquid, and filter through filter-paper. In testing butter place a heaping teaspoonful in a cup, add a couple of teaspoonfuls of hot water, stand the cup in hot water until the butter is melted, stir well, then put the cup in cold water until the butter solidifies, and then filter the liquid. For milk use an ounce of milk and two ounces of a solu- tion of a teaspoonful of alum to a pint of water. Shake well and filter. Add five drops of hydrochloric acid to a tea- spoonful of the liquid, dip a piece of turmeric paper in it, and dry the paper. If either borax or boric acid is present, the paper, when dry, becomes a sherry red. A drop of ammonia turns the color dark green or greenish black. If too much acid has been used, the color may first be brown, even if borax or boric acid is present. The ammonia turns this brown, just as it will turn tur- meric paper which has not been dipped in acid solutions. Saccharin.-Proceed as in the test for salicylic acid. The residue left on evaporating the chloroferm has the sweet taste of saccharin. Sugar is not soluble in chloro- form, so will not be present. If tannins are present the astringent taste may mask the taste of the saccharin. Formaldehyd.-This must be separated by distillation in foods other than milk. Formaldehyd is best tested by using either Hehner's or Leach's test. They are based on the appearance of a violet color when concen- trated sulphuric acid or hydrochloric acid containing a trace of iron is added to the milk. Helmer's Test.-To a few cubic centimeters of con- centrated sulphuric acid, to which a trace of some ferric salt has been added, add the milk to be tested, so as to VARIOUS FACTORS IN THEIR BEARING ON DIET. 121 form a distinct layer on top of the acid, and allow to stand. If formaldehyd be present, even one part to a million of milk, a violet coloration will take place at the junction of the two liquids. Leach's Method.-Dilute the milk with an equal volume of water, and add for each cubic centimeter of the diluted milk i cc. of concentrated hydrochloric acid containing i cc. of io per cent, ferric chlorid solution, to each 500 cc. of acid. The mixture is heated in a casserole over the bare flame to 8o° or 900 C., rotating to break the curd which forms. If formaldehyd be present, a violet color will appear. Hydrogen Peroxid.-This may be detected in milk by the use of a solution of titannic acid (titannium hydrate) dissolved in sulphuric acid. This is added to a few cubic centimeters of milk, and if the peroxid is present, color- ation appears, but varies between a light yellow and a deep orange, according to the amount of peroxid present. A somewhat similar reaction takes place from milk con- taining salicylic acid. The Determination of Artificial Colors.-The Coal-tar Dyes.-If the substance to be examined is not a liquid, dissolve the dye by macerating it in water. Filter, take two or three ounces and add a few drops of hydro- chloric acid, and a few strands of white woolen yarn, or pieces of white woolen cloth. (Before using, the wool should be boiled in water containing a little soda to remove any fat it may contain, and then washed in water.) The wool, which has been boiled, is washed first in hot and then in cold water, and the water pressed out. If the wool is not discolored, the substance tested may be regarded free from artificial colors. If the wool is colored, it may be from coal-tar colors, some foreign 122 DIETETICS FOR NURSES. vegetable colors, or, if a fruit is being examined, the natural coloring-matter of the fruit. Rinse the wool in hot water, and boil three minutes in two ounces of water, to which two drams of ammonia have been added. Squeeze out the excess of water. Natural fruit color is retained, while the coal-tar dyes are usually dissolved in the ammonia solution. Add hydrochloric acid to this fluid until the odor of the ammonia has disappeared and the liquid has a sour taste. A fresh piece of woolen yarn is boiled in this, and if it is colored, the substance examined has been artifically colored. Dull, faint tints must be dis- regarded. If an anilin dye (coal-tar) has been used, the yarn will usually be turned purple or blue by ammonia. The Detection of Copper.-This is often used in coloring canned peas, beans, etc. Mash the substance to be examined and add a teaspoonful of the pulp to three tea- spoonfuls of water and thirty drops of hydrochloric acid. Place the cup in which this has been placed in a water-bath (saucepan containing water will do) and add a bright iron wire nail. Boil hard twenty minutes, stirring frequently with a splinter of wood or a glass rod. If copper is present in any appreciable amount the nail will be plated with copper. Turmeric.-This is added to yellow spices, especially mustard and mace. Mix one-half teaspoonful of the sub- stance to be examined in a white china dish with an equal amount of water, and five or ten drops of ammonia. If turmeric is present, a brown color is formed. If an insufficient amount of the dye has been used to give this test, a more delicate one is to mix a teaspoonful of the substance to be examined with an ounce of alcohol, and then allow it to settle fifteen or twenty minutes. About one-half ounce of the upper liquid is placed in a dish with five drops of concentrated solution of boric acid or VARIOUS FACTORS IN THEIR BEARING ON DIET. 123 borax, and ten drops of hydrochloric acid, and the solution thoroughly mixed. A wedge-shaped strip of filter-paper, two or three inches long, an inch wide at the upper end, and one-quarter inch at the lower end, is then suspended so that the lower end touches in the solution. The paper should not touch the side of the dish. This should be allowed to stand for a couple of hours, and if turmeric is present, a cherry-red color forms on the filter-paper near the upper edge. This red color is turned dark green or almost black on the addition of ammonia. If too much hydrochloric acid has been added, a brownish color results. Caramel.-This is used to color vinegar and other fluids. It should be borne in mind that caramel occurs naturally in malt vinegar. Place about one ounce of the fluid to be tested in two test-tubes, add a teaspoonful of fuller's earth to one, and shake vigorously two or three minutes. Filter through filter-paper. The first part of the liquid coming through the paper should be returned to be filtered a second time. If the filtered liquid, on comparison with the untreated test-tube, is markedly lighter in color, one may assume that the color of the liquid is due to caramel, which is largely removed by the fuller's earth. This test requires a certain amount of practical experience before results can be depended upon. Coffee.-The difference between ground coffee and that which has been adulterated can often be told by the naked eye, especially if not very finely ground. Pure coffee has a uniform appearance, with dull surfaces, while most of the substitutes, particularly peas and beans, have polished surfaces. Chicory is very dark and gummy looking, and the particles have a distinctly astringent taste. On placing ground coffee in a bottle half full of water, shaking it and allowing it to stand, a large amount 124 DIETETICS FOR NURSES. of the coffee will float, while most of the substitutes sink at once to the bottom. The chicory particles will color water, and as they sink slowly to the bottom leave a little dark train behind them. Coffee contains no starch, while all of the substances, except chicory, used for adulteration contain a considerable amount. All ground coffee that gives a starch reaction may be considered as adulterated. Flavoring Extracts.-Vanilla and lemon are the most commonly used and most adulterated. They are fre- quently made with the extract of the tonka bean, which can be determined by the peculiar odor by any one familiar with the two products. The extract made from the artificial vanillin lacks the resins. Caramel is often added to color it, and may be detected by shaking; the foam of pure extracts is colorless, and if caramel is present, little points of color will be seen at the point of contact with the bubbles. The fuller's earth test, given above, may also be used. To examine for the presence of resins, the extract should be evaporated, and when it reaches one-third its volume the resins become insoluble and settle to the bottom, while artificial extracts remain clear. If water is now added, the resin will separate out in a brown precipitate. A few drops of hydrochloric acid should be added, the liquid stirred and then filtered; the resin left on the filter-paper should be washed with water, and then dissolved in a little alcohol, and to one part of this add a few drops of hydrochloric acid, and to another a small particle of ferric alum. The resin from the vanilla bean has only a slight change of color, while with most other resins one or both of these reagents yield a distinct color change. Lemon extract may be tested by placing a teaspoonful of the oil in a test-tube, and adding two or three tea- VARIOUS FACTORS IN THEIR BEARING ON DIET. 125 spoonfuls of water. With real lemon extract the fluid first becomes turbid, and later the oil of lemon separates on the top of the water. If it remains perfectly clear, it is a low-grade product, and contains very little, if any, oil of lemon. Spices.-The detection of adulteration in spices for the most part requires expert knowledge of chemistry and microscopy. Most of the substances used contain starch, but so do most of the common spices. Cloves, mustard, and cheyenne pepper are practically free from starch, and the presence of it may be taken as a proof of adulteration. To test for starch, one-half teaspoonful of the suspected spice should be stirred into one-half cup of boiling water, and boiled for several minutes and then cooled. If the fluid is of very dark color, it should have water added to it, and to this a single drop of iodin is added. If starch is present, it gives the characteristic deep blue color, and if very much is present, it turns black. If no blue color appears, the iodin should be added drop by drop until it shows in the solution. Vinegar.-The simplest test is the odor. If it is not apparent the glass should be rinsed out with the vinegar, and allowed to stand for some hours, when the odor of the residue will be quite distinct; cider vinegar having the fruit odor, and wine vinegar the odor of wine. The residue may also be obtained by evaporation. If the vinegar has been colored, the caramel can be tested by the fuller's earth test. It should be borne in mind that many of the vinegars made from spirits and wood have apple-jelly added to give them the characteristic odor. The Halphen Reaction for Cottonseed Oil.-Carbondi- sulphid, containing about I per cent, of sulphur in solution, is mixed with an equal volume of amyl alcohol. 126 DIETETICS FOR NURSES. Equal volumes of this reagent of the oil to be examined are mixed and heated in a bath of boiling brine for fifteen minutes. In the presence of as little as I per cent, of cottonseed oil, an orange or red color is produced, which is characteristic. Lard and lard oil, from animals fed on cottonseed meal, would give a faint reaction. Renovated butter and oleomargarin may be dis- tinguished from ordinary butter by boiling a small amount in a small pan or tablespoon. It should be melted slowly, and stirred with a wooden splinter or match stick several times during the boiling. Genuine butter boils with little noise, and produces an abundance of foam, while renovated butter and oleomargarin boil noisily, sputter like a mixture of grease and water, and produce less foam. Oleomargarin may also be distinguished from butter and renovated butter by the Waterhouse test. Sweet skimmed milk is used, filling a half-pint cup half full, then heat this nearly to boiling, and add a slightly rounded teaspoonful of the material to be tested. Stir with a wooden rod, and continue heating until the milk boils up; then remove from the heat and cool in a pan containing rather large fragments of ice and a little water. When the cup is placed in the pan the water should reach on the outside of the cup to one-quarter of the height of the milk within. The contents of the cup should be stirred rather rapidly and continuously, and about once a minute the cup should be moved about in the ice so as to facilitate cooling. If the sample is oleo- margarin, the fat gathers into one soft lump, and if it is butter, the fat becomes granulated and cannot be col- lected. When the test is properly carried out the dis- tinction is very marked. CHAPTER IV. THE FEEDING OF INFANTS AND CHILDREN. There are four methods of feeding infants : (^) Breast- or maternal feeding. (£) Wet-nursing, (r) Mixed feed- ing-i. e., breast-feeding supplemented by bottle-feeding. (d) Bottle- or artificial feeding. («) Breast-feeding.-This is the natural and best way to feed a baby, and every mother, if she is capable, should be instructed about nursing her infant. The mental attitude of the mother has much to do with the secretion of milk, and the nurse should never discuss the mother's probable incompetency with her. All conversation should be hopeful and encouraging. If the baby is not gaining properly, tell the physician and not the mother. During the later months of pregnancy the breasts should be examined, and if the nipples are short they should be gradually lengthened by gentle traction several times a day. If they are inverted, a breast-pump may be needed to draw them out at first. During the entire nursing-period the breasts should be washed after each nursing, preferably with a boric acid solution. This does much toward preventing ulcers, fissures, and inflamma- tions. During the first forty-eight hours the child receives practically no nourishment from the breast, the only fluid secreted during this time being a yellowish creamy substance known as colostrum. This has a laxative effect upon the child's bowels. The child should, however, be put to the breast at regular intervals to stimulate the secretion of milk, which becomes free on 127 128 DIETETICS FOR NURSES. the beginning of the third day, although it may be de- layed a day or two longer. During the first two days the nursing child does not require anything except what it gets from the breast. It may, however, be given a teaspoonful or two of warm boiled water or of a 5 per cent, solution of milk-sugar. If the free flow of milk is delayed beyond forty-eight hours the child must be given nourishment, but should nevertheless be put to the breast at regular intervals, to help establish the milk secretion. Neglect of this important point often causes a failure in the secretion. If necessary the mother may be instructed as to the manner in which to give the child the breast. The child should lie on the right or left arm, according to whether the child is nursed at the right or left breast. If the mother is in a sitting posture her body should be inclined slightly forward. With her free hand she should grasp the breast near the nipple, between the first two fingers. If, owing to the too free flow of milk, the child takes the milk too rapidly, this may be checked by slight press- ure of the fingers. The child should nurse until satis- fied. The contents of one breast are generally sufficient for one nursing, and the breasts should be used alter- nately. When satisfied the child will usually fall asleep at the breast. Under ordinary conditions nursing should last from about ten to twenty minutes. If the milk is taken too rapidly, vomiting may ensue during or im- mediately after feeding. If too much is taken, it is regurgitated almost immediately. If the infant consumes more than half an hour in nursing, the breast and the milk should be examined. As the infant grows it requires and takes more food, and consequently nurses somewhat longer than in its earlier days. THE FEEDING OF INFANTS AND CHILDREN. 129 Good nursing habits should be insisted upon, as many attacks of indigestion, colic, and diarrhea may be traced to improper nursing. When good habits are estab- lished there is generally but very little trouble, the suc- cess of the training depending largely upon how it is done. Regular hours for feeding should be fixed and adhered to; if the child is asleep at the nursing hour it may be aroused, for it will almost invariably go to sleep after nursing. After the last feeding, which should be at 9 or io o'clock, the child should be quieted and allowed to sleep as long as it chooses. During the first month or two the infant will, as a rule, awaken be- tween I or 2 o'clock and again at 4 or 5 o'clock. After two or three months it will require but one night feed- ing, and after five months of age the average infant will sleep all night without nursing. Wheo the change is being made and the child awakens for its accustomed nursing, it should be given a little warm water from a bottle and quieted, but not taken up. At present the most frequent practice is to use a four-hour schedule. Many infants do not thrive on this, and a three- or even two-hour interval may be sub- stituted if necessary. When short intervals are used care should be taken not to feed the child more food than is required. The night feedings have to be regu- lated according to the child. We prefer giving a feeding at 10 p. M. and none until morning unless needed, as in the case of premature or small infants. Many prefer to give one night feeding at midnight. We have no fixed rules, but frequently employ the following schedule, especially where the infant does not seem to do well on the four-hour schedule: 130 DIETETICS FOR NURSES. Age. Number in twenty-four hours. Intervals during the day. Night nursing between 9 P. M. and 7 a. m. i st day 4 6 I 2d day 6 4 I 3d day to 13th week 7 3 2 3d to 5th month 6 3 I 5 th to 12 th month 5 4 O If the child is small or ill it will run somewhat behind the above schedule, and if it is large and robust some- what ahead of it. It is a good general rule to feed the child according to the age to which the child's weight corresponds. The child's weight is the best index to its nutrition. During the first few months it should be weighed twice a week, then once a week, and during the second six months twice a month. If the mother's milk is unsuited to the child it is fret- ful, the weight remains stationary or the child loses, and there may be bowel disturbances. In such cases the physician frequently examines the breast-milk to deter- mine its quality, and he may either decide to wean the child or to take certain measures to improve the breast- milk. The following are the most frequent means of modifying the mother's milk : I. If the milk is too rich the diet should be limited, especially as to the amount of meat taken. All alco- holic and malted drinks should be prohibited. With plenty of fresh air and exercise, such as walking, the desired effect will generally be brought about. The exercise should be carried to the point of fatigue. 2. When the milk is good but deficient in quantity, the supply may be increased by massage of the breasts three times a day and from five to ten minutes. A good malt THE FEEDING OF INFANTS AND CHILDREN. 131 extract should be given with the meals, plenty of milk should be given, and exercise and fresh air looked after. 3. When the milk is deficient both in quality and quantity the above means should be used, and the phy- sician generally prescribes iron in addition, and special orders about the diet. 4. When the quantity is normal but the quality poor the same means should be tried, but these cases are prac- tically hopeless, and the physician usually decides to wean the child. The First Few Days.-The first few days of a baby's life are very important ones, and many subsequent troubles may be traced to inadequate supervision of the child during this period. This happens not only among the ignorant and ill-informed, but also in the most intelligent classes. During the first forty-eight hours the child receives practically no nourishment from the breast, the only fluid secreted during this time being colostrum. This has a laxative effect upon the infant's bowels, emptying them of the dark brownish material, known as meconium, that has accumulated during uterine life. The child should, however, be put to the breast at regular intervals, so as to establish a free flow of milk. This generally begins on the third day, but may be delayed. Catnip, fennel tea, and the like should not be given. It is very important that the breasts be emptied at regular intervals, as this is the greatest stimulation to milk secretion there is, not only during the first few days, but during the whole of lactation. If the child is too feeble to nurse properly the secretion of milk may be seriously interfered with. Throughout lactation if the breasts are not emptied there is a tendency for the milk to become poor in quality. During the first few days if the milk supply is not established it may be neces- sary to give the child some additional food, but it should be put to the breast at every nursing time so as to stimu- 132 DIETETICS FOR NURSES. late milk secretion, then immediately afterward given whatever food is prescribed. During the first few days the child is often neglected and may become seriously, even fatally, ill from starva- tion from nursing on a dry breast. A normal milk flow may be established even seven or eight days after birth, so that until this time has elapsed it is not well to abandon efforts at having the child nurse, though sufficient food must be supplied during this period. With accurate scales the amount the child is getting from the breast may be determined by weighing immediately before and after nursing. If the child is not getting sufficient food it does not gain, or even loses, weight. It is fretful, worried, and cross; there are often greenish or brownish stools containing a large amount of mucus. The mental attitude of the mother has a marked effect on the milk condition, and her condition should not be discussed with the nurse in her presence. The child is best weighed in another room. Contra-indications to Maternal Nursing.-The mother should not nurse the child if she has tuberculosis in any form, as she not only exposes the child to infection, but hastens the progress of the disease in herself. If she has pulmonary tuberculosis, nursing the child will almost certainly prove fatal to her. When the mother has had any severe complications late in pregnancy or in connection with parturition, she should not suckle her child. Examples are nephritis, convulsions, severe hemorrhage, or septic infection. Nursing is contra-indi- cated if the mother is choreic or epileptic. When no milk is secreted nursing is, of course, im- possible. When the mother has shown on two previous occasions that she is unable to nurse her child, a third attempt may be made, but the child must be watched very closely and not allowed to suffer from underfeeding if no milk is secreted. THE FEEDING OF INFANTS AND CHILDREN. 133 (o) Wet-nursing.-With the advent of better meth- ods of artificial nursing the wet-nurse is disappearing, at least in the United States. Some infants will not thrive on any but human milk, and sometimes wet- nurses are still employed. Their choice should always be supervised by a physician. (c) Mixed Feeding.-One full feeding a day in place of a nursing is often given to permit weak or nervous mothers to get a good night's rest, or it may be given in daytime to allow the mother greater freedom. At each other nursing period the child is put to the breast and left long enough to empty at least one of them. If the child is not getting enough from the breast it may be necessary to give a certain amount after each nursing. The child is put to the breast first and then the amount necessary to make up the feeding given immedi- ately after. The mother's milk in these cases often becomes poor and weaning may be needed. In some cases in bottle-fed infants who are not doing well human milk is often given either from the breast of a wet-nurse or small amounts may often be ob- tained from some friendly mother, or, in cities, from maternity hospitals. In premature, improperly fed young in- fants, inanition, marasmus, and other conditons this plan is of great value. (d) Artificial Feeding.-When it becomes necessary for the child to be fed on the bottle, the milk-mix- ture to be used should be prescribed by the physician, and the nurse instructed by him in the preparation. It happens very often that many details are left to the Fig. 3.-A hygienic nurs- ing bottle (De Lee). 134 DIETETICS FOR NURSES. nurse, and frequently even the entire matter. The fol- lowing short account will help her understand what is expected. (Full details will be found in our larger book, "Diet in Health and Disease.") The average infant will not thrive on plain cows' milk. To render it more fit for digestion it is diluted with water, lime-water, cereal gruels, and other articles of diet. The necessity for this will be seen on considering the differ- ences between cows' and mother's milk. Proteins.-These differ in amount and character. Mother's milk contains 1.5 to 2 per cent, of protein, on an average. Of this two-thirds are lactalbumin and one- third casein, the latter being much more digestible than the former. In cows' milk there is about 3.5 per cent, protein, of which five-sixths are casein and one-sixth lactalbumin. The casein of mother's milk is coagulated in the stomach in small flocculent masses. Cows' milk is coagulated in large curds. The proteins of cows' milk may be prevented from forming large curds by the addition of lime-water, barley-water, and gruels. The protein in mother's milk is best for infants; as low as 7 per cent, of the total calories will insure growth; with cow's milk the percentage must be 14 to 18 per cent. This is due to the differences in the make-up of the two substances. Cow's milk contains less of certain important amino-acids needed for infant growth. Vege- table proteins are still less suitable for infant nutrition. If a diet containing insufficient protein is used over long periods, it causes slow growth, anemia, muscular weakness, and other troubles. Too much protein makes for constipation, white dry stools. Protein milk and similar preparations are used to check diarrhea and fermentation. Sugar.-Milk-sugar is present in mother's milk in a THE FEEDING OF INFANTS AND CHILDREN. 135 very constant proportion of 6 to 7 per cent. In cows' milk it averages 4.5 per cent. In artificial feeding sugar must be added to the food to make it approxi- mately 7 per cent, of the total. Cane-sugar may be used with success in most of the normal babies. Some prefer milk-sugar, but mixtures of maltose and dextrose are less apt to ferment and are less irritating than the pure sugars. After diarrhea they are to be preferred except where some idiosyncrasy exists. Malt extracts, malt soups, malted milk, and gruels are also used to in- crease the carbohydrate content of the food. The caloric values of these are given in a table a few pages further on. Fat.-The fat in human milk averages 4 per cent.; that of cows' milk is the same. When the cows' milk has been diluted the quantity of fat must be made up by adding cream or using the upper part of the milk after the cream has risen. Care must be taken not to give too large quantities of fat, as it is a common cause of digestive disturbance. Salts.-The inorganic salts in the milks vary in about the same proportion as the proteins. They need not be considered in modifying milk for babies. Reaction.-Mother's milk is always alkaline, while cows' milk is neutral or acid, and it becomes more and more acid on standing. Alkalis are often used to cor- rect this acidity and to prevent the formation of curds. Lime-water in the proportion of 5 per cent, of the total mixture is most often prescribed, but most babies do about as well without this addition. Lime-water is added in much larger quantities in certain cases; 20 per cent, is often used, while 50 per cent, stops the digestion of proteins in the stomach. Sodium bicarbonate or sodium citrate are often used in the proportion of 1 to 2 grains to each ounce of milk used in the mixture. 136 DIETETICS FOR NURSES. The Fluid Needs of Infants.-In each twenty-four hours the infant requires a certain amount of fluid, about 3 ounces per pound for the first four months, and less later, about 2| ounces per pound, and in late infancy 2 ounces per pound. A three months' baby weighing 12 pounds would be expected to take about 36 ounces in twenty-four hours. This is best given with the milk, but a few ounces may be given a couple of times a day, especially in summer when the fluid needs are somewhat greater. The Caloric Needs of Infants.-The total caloric needs of infants has not been definitely determined, and they vary greatly under different conditions. An infant that sleeps a great deal will require less food than one who is very wakeful, and the high-strung, nervous, and very active child requires considerably more than others. Children require more per kilo, or per pound of weight, than grown people, partly because they need a certain amount for growth and partly owing to the fact that the proportion of surface is greater in the small body. Atrophic children and those under weight for their age require more than the normal child, and the needs of premature children are much larger than ordinarily would be expected. Children overweight require less. The food requirements of infants according to present-day teaching are 60 calories per kilo (28 per pound) the first few days, in the second and third week 100 (45 per pound), increasing to 120 (54 per pound) at six weeks, at the end of the first year 100 per kilo (45 per pound). There is a gradual fall until the sixth year, when the average is 80 per kilo (36 per pound), fol- lowing gradually until puberty, when the requirements are about the same as adults. Girls require a few calories less. Do not forget that there are many variations from THE FEEDING OF INFANTS AND CHILDREN. 137 these figures, which represent averages. Variations are caused by temperament, nervous children needing more; by climate and season, more in cold than hot; by mus- cular activity and other factors. Observation, common sense, and judgment cannot be replaced by printed tables. Artificially fed children apparently need more than those fed at the breast. Premature infants require from 100 to 132 calories per kilo. If the percentage composition of the infant's food is known, the number of calories they contain may be approximately esti- mated by Fraley's method, which consists in adding together twice the fat percentage, the protein percent- age, and the sugar percentage, and multiplying this sum by one and a quarter times the total quantity ex- pressed in ounces. This may be expressed in the fol- lowing formula: 2F + P + S x <XQ = Calories. An easy rule is twice the fat percentage plus protein percentage, multiplied by 1.25, gives the calories per ounce of food. Holt and Howland suggest multiplying by 1.3. From the table on page 138 it is easy to calculate the caloric value of any ordinary mixture. Caloric Feeding.-The infant needs a certain amount of protein per pound of body weight. This is supplied by i| ounces of milk per pound. To make a milk formula for a given baby, take the amount of milk required by the weight, dilute it with plain water or a cereal water, according to the fluid needs of the body as stated else- where, 'add 1 ounce of sugar for each 20 ounces of the total mixture. If the total number of calories required according to the rules given under that caption are not supplied they can be made up by adding more fat-i. e., by using a top milk, or by adding more starch in sugar. 138 DIETETICS FOR NURSES.

Approximate Measures. THE FEEDING OF INFANTS AND CHILDREN 139 In former days complicated tables and formulas were used in calculating what should be used to feed the baby. A simpler and more satisfactory method is to figure out the number and size of the feedings. For each pound of the baby's weight one and a half of whole cow's milk or its equivalent must be supplied as a minimum. Often it is necessary to give more than this, and up to 2 ounces to the pound may be used if necessary. This will supply the protein and a low but what is generally a satisfactory fat content. To this sufficient water or cereal gruel must be added to bring up the total quan- tity and sugar, usually 1 ounce for each 20 ounces of the mixture. Often less sugar must be used, especially if there is a tendency to fermentation or gas or any evidence of indigestion. Changing the kind of sugar may also help or, what is better, the use of mixtures of cereals, gruels, and sugar, or of malt foods. There are times when it is desirable to use less fat. In such cases skimmed milk or buttermilk may be used, but the infant should not be kept too long on low fat feeding and care should be taken to see that the total number of calories given in each twenty-four hours approximates the theoretic requirements. Higher fats may be at times used to advantage. We believe that mixtures rather high in fat give better results in the long run, but there is great danger of producing a fat indigestion with serious consequences, so that unless the child is super- vised by an expert these should be used cautiously if at all. Such formulas are easily obtained by using top milk. As an example a normal baby who has been on cow's milk weighs 10 pounds. It may be given 6 ounces at a feeding and five feedings in twenty-four hours; a total of 30 ounces. MILK MODIFICATION 140 DIETETICS FOR NURSES. i J ounce per pound = milk 15 ounces = 300 calories. Dextrimaltose ij ounces = 45 tablespoons = 180 calories. 480 calories, or 48 calories per pound. Water to make 30 ounces. This might be varied if the four-hour schedule did not give good results, and six feedings of 6 ounces each given, the same number of calories, but the food more diluted. Barley-water might be substituted for plain water if the stools were not perfectly smooth or oat- water might be used if there was constipation. In this manner an endless number of formulas may be worked out using but one or two known facts as a basis. The mistake usually made is to figure out a formula that is theoretically correct and to persist in its use regardless of whether the baby thrives or not. If the baby does not gain regularly in weight some- thing is wrong, but do not be impatient in stationary weight in infants who have been improperly fed and whose digestion has been impaired in consequence. A certain amount of time is required for readjustment. Dennett gives the following conditions in which the caloric requirements should not be fulfilled: 1. In the newborn (for the first two weeks). 2. Normal infants abruptly weaned from the breast (until their tolerance for food can be gradually in- creased). 3. Infants whose previous food has not contained cow's milk (until the milk and sugar can be gradually increased). 4. Infants who have been overfed (until their di- gestive apparatus has had a chance to recuperate). 5. Infants who have been underfed (until their toler- ance for food can be gradually increased). THE FEEDING OF INFANTS AND CHILDREN. 141 6. Infants who have diarrhea or who have recently had diarrhea (until the stools have become normal and the tolerance for food has been gradually increased). 7. Infants who have excessive vomiting or who have recently recovered from excessive vomiting (until vomit- ing has stopped and the tolerance for food increased). 8. Infants with loss of appetite (until all food is greedily taken). 9. Infants who are partially breast fed (until they are entirely weaned, because it is impossible to determine how many calories they are getting from the breast). The Calculation of the Composition of a Milk Mixture.-This is most easily done by multiplying the percentage of fat, sugar, and protein in the food by the number of ounces used,'and dividing by the total number of ounces of food prepared, and adding in the percentage of sugar added. Thus, in a formula of which milk 6 ounces, milk-sugar 1 ounce, and water to make 20 ounces, the percentage of fat would be n of 4, or 1.2; the per- centage of sugar of 4.50, or 1.35; and the protein of 3.50, or 1.05. The ounce of sugar added amounts to 5 per cent., so the sugar percentage would be 6.35. The Pirquet System of Nutrition.-During the late war large groups of children were fed abroad and a new system was devised by Pirquet to regulate the amount furnished. This system, while of value in feed- ing large groups, does not seem to be much used in America. It is based on the sitting height, i. e., the dis- tance from the surface of the seat on which the body rests to the top of the head, which bears a close relation to the cube root of the body weight. The term "pelidisi" is used to express the formula which is the cube root 142 DIETETICS FOR NURSES. of ten times the body weight which approximately equals the sitting height. The pelidisi have been worked out and are given in Pirquet's tables.1 The unit of nutrition used by Pirquet is the "nem," the initials of Nahrungs- Einheit-Milch or Nutrition-Equivalent-Milk, and is the full value of a gram of human milk or 1 (large) calorie equals 1.5 nems, a decinem is one-tenth of a nem, a dekanem is 10 nems, and so on. Hektonems or 100 nems is most used in computing diets. This method of computing diets cannot be presented in a small space, and, inasmuch as it is but little used in America, the reader is referred to the reference given for fuller information. I/aboratory Method.-In certain cities there are milk laboratories, known as the Walker-Gordon labora- tories, where physicians may send prescriptions for milk mixtures, which are made at the laboratory and sent to the home of the infant. The only procedure is to re- move the cotton stopper from the bottle and replace it with a nipple and warm the milk. Matema Graduate Method.-Where a nurse is thrown on her own responsibility, the Estraus Materna Graduate is of great service. With it six modifications can be made, which are sufficient for the average child. Sometimes, of course, a child will be found whose diges- tive powers do not correspond with the few formulas furnished. The apparatus consists of a glass jar with a lip and seven panels, and a capacity of 16 ounces. One of the panels exhibits an ordinary ounce graduation; the other six panels present six different formulas for the modifica- tion of cows' milk, each formula being so arranged as to keep pace with the infant's growth, viz.: 1 An Outline of the Pirquet System of Nutrition, W.

The quantity desired for twenty-four hours is next to be considered, and the apparatus filled-once, if 16 ounces or less are required for the twenty-four hours; twice, if from i6to 32 ounces are required for the twenty- four hours; three times, if from 32 to 48 ounces are re- quired for the twenty-four hours. Baner's Method.-If the percentages have been given, the quantities of milk, cream, sugar and water needed may be determined by the following formulas: Quantity desired (in ounces) = Q. Desired percentage of fat - F. Desired percentage of sugar = 5. Desired percentage of protein = P. To find in ounces : Cream (16 percent.) = Q x (F- P). Milk = 22^-C 4 Water = ^-(C+J/). ■n n 5- P x Q. Dry milk-sugar -. too Example.-Suppose it is desired to make 40 ounces of a 4 per cent, fat, 7 per cent, sugar, 2 per cent, pro- tein mixture. By substituting the figures in the equa- tions above we have- Cream =l?x 2 = 6| ounces. 12 Milk =^-- - 6f= 13| ounces. Water = 40 - 20 = 20 ounces. Sugar = 5224- - 2 ounces, too Malted gruels, various diastase preparations, such as diastoid, maltine and diazyme, as well as the malted foods, such as Mellin's, are sometimes used to prepare the infant's milk, especially if there is constipation. Bar- THE FEEDING OF INFANTS AND CHILDREN. 145 ley-, oatmeal-, and rice-water are sometimes used to dilute the milk to break up the curd. Barley- or rice-water is preferred when there is a tendency to loose bowels, and oatmeal-water when there is constipation. Cereal gruels are probably best not begun before the eighth or ninth month, unless there be some special indication for so doing. Other Foods for Infants.-Many other foods may be of service under certain conditions. The following are the most important: Dried Milk.-There are two types of dried milks. In one the milk is dried and mixed with other food sub- stances, usually carbohydrates. Malted milk and Nestle's food are of this class and have been mentioned elsewhere. When this type of food is used orange juice or some other antiscorbutic should always be given. In the other type the milk is dried very rapidly either by passing it over heated cylinders, the Hatmaker proc- ess (Dryco, Mammala), or by spraying it through small openings into a heated vacuum, the Merrill-Soule process (Klim). These milks retain their vitamins, but are slightly lower in fat than ordinary raw milk. They are very useful in infant feeding. We are inclined to believe that in the next quarter of a century such milks will be used extensively. They are useful in traveling, in hot climates, and where pure milk cannot be obtained. In certain forms of digestive disturbances and in some cases of malnutrition they are most useful, as they appear to be more digestible and more absorbable than fresh milk. They are sterile and so help prevent diarrhea, but there are occasional children who have loose movements on dried milk, especially if the mixture is a little too rich. We almost always give orange juice or some other anti- scorbutic, although this is apparently not necessary. We 146 DIETETICS FOR NURSES. also give children fed on them small doses of cod-liver oil from time to time. Dried milk should be made fresh at each feeding, using boiled water, and some form of sugar or carbohy- drate may be added, as in using fresh milk. Dryco contains approximately: Per cent. Fat 12 Lactose 44 Protein 7 Moisture 3 100 One ounce by weight yields 127 calories. Eight level tablespoons (level with a knife), 1 ounce by weight. One level tablespoon, 16 calories. The maximum strength for infant feeding is one level tablespoon to the ounce, but sometimes where a con- centrated food is desired the mixture may be made stronger and used in smaller quantities. We usually add sugar to bring up the caloric value by adding 1 or 2 teaspoons of sugar or dextrimaltose to each feed- ing, according to circumstances, and sometimes use it without sugar. One level teaspoonful of sugar equals about 10 calories and of dextrimaltose about 6 calories. It is well to use a measure or measuring glass. A simple rule is to give 2| level tablespoons per day for each pound of the infant's weight. Dissolve in one more ounce of water than there are tablespoons of dryco per feeding. The following has been suggested: THE FEEDING OF INFANTS AND CHILDREN. 147 Weight of baby in pounds. Amount each feeding, level tbsp. Amount of water each feeding, ounces. Number of feedings per day.

Always start under the amount given and increase. If there is too rapid gain or a tendency to loose bowels reduce the amount of dryco. If there is constipation use dextrimaltose and if necessary either barley- or oat-water as a diluent. We have used this simpler schedule, varying it with the individual needs: Weight, pounds.

The Merrell-Soule Milk.-This is made by the Mer- rell-Gere spray process. The milk is first pasteurized by the holding process and partially concentrated by vacuum. It is then sprayed under heavy pressure into a chamber through which a current of filtered warm air is passing. The milk is broken up into a very fine spray and falls to the bottom as a dry powder, contain- ing less than 3 per cent, moisture. The claims made for this process are that the fat globules are broken up into a small size; casein curdles in finer and softer floccules; that when reliquefied it re- mains uniform, there being no tendency for the butter- fat to rise. It is made in two strengths, whole milk and skimmed milk. Four level tablespoons equal one ounce. The following shows the percentage composition of the various mixtures: Powdered whole milk.

It is also of use for the infants who are not gaining, and as a temporary food when pure milk cannot be obtained, as in traveling. Where only one bottle feeding is given a day, in breast-fed children, it is also useful. We gener- ally use it in dilutions of I in 12, or 1 in 8. It should be measured in a graduated glass, as otherwise too much may be used, and it may be diluted with plain boiled water or, if desired, with a thin cereal gruel. The gruel may be made from the soy-bean flour and barley flour, a mixture which is particularly useful for this purpose. Cream may be added later, or olive oil may be given in addition. Orange-juice should be given every other day, or even every day, to prevent scurvy. If condensed milk is used too long without other feeding, anemia, scurvy, or rickets is liable to de- velop. Condensed milk furnishes about 100 calories per ounce. Buttermilk.-Buttermilk has been much used in recent years, and is useful where it is necessary to use a food 150 DIETETICS FOR NURSES. low in fat and sugar. The curd of the milk is precipitated in small flakes and most children digest it easily. It also contains lactic acid bacilli in large numbers, and this may be of especial service in certain forms of intestinal trouble. It may be diluted with water or with cereal gruels, and sugar may be added if desired. Acid Milks.-These are extensively used and are whole milk, to which lactic acid bacilli have been added. This milk is sold under various names, and often has other food substances mixed with it. It differs from buttermilk in having all of the fat left in it. It is of particular value in certain forms of diarrheal trouble and indiges- tion. It may be diluted to the same degree as ordinary milk. Kumiss and other fermented milks are sometimes used. Albumin Milk.-This is a mixture which has been much used of late, and is sometimes called Eiweiss milk or protein milk. This is prepared by heating one part of the whole milk to ioo° F., adding four teaspoonfuls of essence of pepsin and allowing the mixture to stand at ioo° F. until the curd is formed. The mass is placed in a linen cloth and the whey strained from the curd. The curd is removed from the cloth and pressed through a fine sieve two or three times, using a wooden mallet or spoon. While doing this, one pint of water is added. The precipitate ought to be very finely divided and the mixture should look like milk. To this one pint of buttermilk is added. This milk mixture is low in sugar, contains lactic acid bacilli, and has a food value of about 370 calories to the quart. In the beginning it must not be mixed with any other kind of food, not even with human milk. The infant should be given only water, THE FEEDING OF INFANTS AND CHILDREN. 151 usually for twenty-four hours, and then small amounts of the albumin milk given and, if all goes well, larger and larger amounts. Malt sugar or mixtures of maltose and dextrin are sometimes added. Albumin milk re- quires care in its use. It should never be employed ex- cept on physician's orders, as great harm may result from its improper use. See also under Diarrhea. Calcium caseinate, marketed under such names as larosan, casec, and protolac, are frequently used to modify milk used in feeding babies with diarrhea or digestive disturbances. See Diarrhea for methods of preparation and use. Gelatin.-In chronic intestinal disease gelatin is often added to the diet, mixing it with milk or giving it as a jelly. Gruels.-Cereal gruels, as a rule, are made by cooking the flour and water for fifteen to twenty minutes. If the grains of the cereals are used, they must be cooked for from three to four hours. Barley, rice, oatmeal, corn- meal, and soy-bean flour are the most frequently used. Plain gruels cannot be made much stronger than 2 ounces to the quart. Dextrinized gruels may be made as high as 8 ounces to the quart. One level tablespoon- ful of the cereal flour weighs ounce. The cereal flour contains about 100 calories to the ounce, so that underfeeding, which occurs when they are used alone, is easily explained. Soy Bean.-From 1 level tablespoonful to 3 ounces of the soy flour are used to the quart. These gruels do not thicken during cooking, as they contain no starch and readily settle on standing. This may be overcome by adding 1 to 2 tablespoonfuls of barley, oat, or wheat gruel flour before cooking, which will add 0.6 per cent, to 1.2 152 DIETETICS FOR NURSES. per cent, starch to the gruels, and also slightly increase the percentage of protein. A good standard gruel, which may be diluted as desired, may be used by using I ounce of soy-bean flour, 2 ounces of barley flour to a quart of water. This contains 2 per cent, protein, 0.6 per cent, fat, 5.10 per cent, carbohydrate, with a caloric value of 320 calories, or 10 calories per ounce. This is just half the value of milk. It is of particular use in maras- mus, in using condensed milk, in cases in which cows' milk does not agree, and in certain forms of intestinal trouble. Olive Oil.-This is useful where cream disagrees when foods low in fat are given, sometimes in constipation and other certain digestive disturbances. From 1 to 4 tea- spoonfuls may be given daily, and it is best begun by using small amounts at first and then increasing gradu- ally until the full amount is given. Malted Milk.-This is a very valuable food for tempo- rary use when pure milk cannot be obtained, and it is also of value in certain digestive disturbances. It may also be added in milk mixtures, and it is also useful in consti- pation. If used over considerable periods, orange-juice or other fresh juices must be given, and fat, either cream or olive oil. Malt Soup.-Various malted preparations are used and are generally known as malt soups. Generally the malt- soup extracts of various kinds are used, but any thick malt extract and potassium carbohydrate may be used in making malt soups. Fifty grams (2 ounces) of wheat flour are added to J liter (11 ounces) milk with constant stir- ring, and in a second vessel malt-soup extract, or malt extract, with the addition of 100 c.c. (2| drams) of a 10 per cent, solution of potassium carbonate are dissolved in THE FEEDING OF INFANTS AND CHILDREN. 153 j liter (20 ounces) of water at 1200 F. The contents of the two vessels are then mixed and boiled from two to five minutes. This mixture has a somewhat higher food value than cows' milk, and may be diluted with water as desired. Dry malt soup preparations are now made which greatly facilitate the use of this form of feeding. Malted Gruels.-These are prepared by making a cereal gruel in the ordinary way, then adding a teaspoonful of good malt extract or a teaspoonful of diastase. The mixture should be cooled before the diastase is added and then thoroughly stirred. Beginning Bottle - feeding. - The percentages should be low at first, far below what would be given the child if it were accustomed to cows' milk. As soon as the infant's stomach is accustomed to the milk, it should be rapidly increased in strength until the proper mixture for the child in question is reached. Technic of Modifying Milk at Home.-Great care and cleanliness should be used. The vessels and instruments used should, if possible, be kept solely for the use of the infant. All bottles, pitchers, and other utensils should be thoroughly boiled or scalded before using. The nursing-bottles should have rounded bot- toms, to facilitate cleansing. It is a good plan to keep the bottles sweet by filling them with a solution either of boric acid or sodium bicarbonate, a teaspoonful of either drug to a pint of water. The nipple should be ordinary short black rubber ones and white rubber, and all nipples with tubes or complicated structure avoided, as they are hard to clean and are liable to lead to bowel troubles. It is a good plan to have several nipples on hand, and to boil them when first bought, and once a day 154 DIETETICS FOR NURSES. afterward. They should be thoroughly washed after each using, turning them inside out for that purpose, and kept in a solution of boric acid or sodium bicarbon- ate. The milk should drop rapidly when the bottle is held upside down. If it does not run fast enough, the holes in the nipple should be enlarged by using a red- hot darning-needle. If the flow is too free it may cause vomiting, and such nipples should be rejected. It is best to prepare the entire quantity for the twenty- four hours at one time. If the weather is warm the milk should be either sterilized or Pasteurized, unless an ex- ceptionally pure milk is being used. If neither can be done, the feedings maybe prepared one at a time as needed. The sugar, either milk or cane, is dissolved in hot water. If the solution is not perfectly clear, it should be filtered. This is poured into a pitcher with the lime- water or the soda, and the milk or milk and cream and other ingredients, if any have been ordered, should be added. After mixing, the nursing-bottles are filled with the proper quantity for each feeding, and the bottles stoppered with sterile raw cotton. The bottles are then sterilized or Pasteurized as directed, and then, after rapid cooling, are placed in the refrigerator. At the feeding- hour the bottle is heated and a nipple substituted for the cotton stopper. Premature Infants.-These should be kept warm and supplied with sufficient fresh air. Babies weighing 5 pounds and over will generally take the breast, but it may require some days and patience. If they do not take a nursing the milk should be drawn from the breast and given by bottle, Breck feeder, dropper, or tube. This is the procedure for feeding smaller infants. The milk may come from a wet nurse and the age of the latter's child is of no importance as long as the milk THE FEEDING OF INFANTS AND CHILDREN. 155 is normal. It is, however, important that the infant get the colostrum from the mother the first two days if it is possible. If the milk is very rich or if there is any digestive disturbance some or most of the cream may be taken off, and it may be necessary to dilute the milk with boiled water, and in these cases small amounts of dextrimaltose may be added. Only a few grains should be given at first, as larger amounts oc- casionally cause loose bowels; if all goes well it may gradually be increased to 1,2, or even 3 per cent. The interval between feedings depends largely on how much can be given at a feeding and no fast rules can be given. The main thing is to get the infant's needs covered. There is considerable difference of opinion as to what the need is, but it may be figured at from 50 to 80 calories per pound, the smaller the infant, the greater the need. Great care should be taken not to overfeed, but in our experience danger of under- feeding seems to be greater than of overfeeding. These infants should be given small (5- to 10-drop) doses of cod-liver oil from time to time as they gain and grow older. Budin gives the following table showing the amounts taken by actual infants of various weights: Age, days. Weight less than 1800 grains (about 4 pounds), ri infants. Ounces.

During the second year of life as much care is required in feeding as during the first. The fear of the second summer would largely be overcome if the child were not allowed to eat food unsuited to its digestion. The fact that some children thrive on almost any kind of food is no excuse for permitting a child to have the same food as its elders, as is so often done. Most of the ill- ness and many of the deaths of childhood are traceable to improper diet. During the second year milk should form the basis of the diet. In cities or where the milk-supply is not above suspicion, it is best to pasteurize the milk until the second summer has been passed, or even longer if circumstances warrant. As a rule, the milk requires but little modification, and after the twelfth month, and often before, may generally be taken unmodified. As the child is now able to digest starchy food, milk-sugar may be omitted. In cases where the milk is not thoroughly digested, as is evidenced by curds in the stools, lime- water may be used, and may be added in quantities of from 5 to io per cent., or even more if necessary. If the milk is very rich, it should be diluted either with lime- water or usually with plain sterile water-three parts of milk to one of water. If the milk is poor or if milk that is not rich does not agree with the child, it may be prepared as follows: Fill a glass three-quarters full of milk, add one or two tablespoonfuls of cream, and fill to the top with plain water. If this does not answer, add a tablespoonful of lime-water. During illness, and often under other circumstances, the alkaline carbonated waters will be found useful for diluting the milk. If the milk is poor, another plan is to use the upper two-thirds of the milk. THE FEEDING OF INFANTS AND CHILDREN. 157 Starchy food may be given in the form of gruel, either alone or, what is better, mixed with the milk. Barley- gruel or, if there is a tendency to constipation, oatmeal- gruel is added, one-fifth or one-fourth part of gruel being added to each feeding. The gruel should be freshly pre- pared and mixed immediately with the milk. A pinch of salt and a very small quantity of cane-sugar may be added to render it more palatable. It may then be Pas- teurized like ordinary milk. The bottle should be dispensed with and the food be taken from a cup or spoon. If the bottle is not taken from the child early, it may be difficult to break it of the bottle habit. The following diet lists for different ages will be found useful: DIET LIST-SEVEN TO NINE MONTHS Foods permitted: Breast or substitute. Junket. Orange or prune juice, strained stewed apples.

The Diet from Two and One-half to Six Years.-Milk may be allowed with every meal (may be omitted from dinner if desired). The average child should take a quart a day, plain or, when plain milk is not thoroughly digested, modified as for younger infants. Cream.-Two to eight ounces a day mixed with the milk, taken as a beverage, with cereals, etc. Bread and biscuit may be allowed with every meal- stale bread, dried bread; the so-called "pulled bread," zwieback, and the various forms of biscuits or crackers. Cereals.-Almost any kind of cereal for breakfast; oatmeal and wheaten grits are the best. Rice and hominy for dinner. Barley is useful in soups. THE FEEDING OF INFANTS AND CHILDREN. 161 Vegetables may be allowed for dinner-potatoes in some form or a cereal with one green vegetable; spinach, cauliflower tops, and the like are the best. Eggs are very good, but children are apt to tire of them easily. They should be given for breakfast, as a rule, but never day after day. Meat.-Allowed once a day for dinner, and in older children for breakfast occasionally. Boiled or broiled fish may be given for breakfast or dinner. Broths and soups of simple composition may be eaten. Meat-broths with cream and cereals are especially nutri- tious. Desserts.-Once a day, with dinner. Plain custard, milk- and rice-pudding, bread- and custard-pudding, and junket are the best; ice cream once a week. Fruit should be given once daily, and only ripe fresh fruit, in season, should be used. The best are oranges, baked apples, and stewed prunes. Ripe peaches, pears, grapes without skins or seeds, may also be given. Fresh juice of berries in small quantity, strawberries in perfect con- dition sparingly. Ripe cantaloupe and watermelon in moderate quantities may also be allowed. Great care should be used in choosing and giving fruit to children. It is a very important article of diet, but if stale, spoiled or unripe, is capable of doing much harm. Too much should not be given in hot weather. Lemonade is use- ful during very hot weather. According to Meals.-Breakfast.-Every day, milk to drink. A well-cooked cereal with salt and cream, but little or no sugar. Bread and butter. In addition to the above, one of the following every day: Eggs lightly boiled, poached, and for older children scrambled or made into a plain omelet. Boiled or 162 DIETETICS FOR NURSES. broiled fish. For older children a very little finely chopped beef, mutton chop, or beefsteak. For younger children meat at breakfast is not, as a rule, necessary. Fruit may be given before or after breakfast, during the latter part of the morning, or at about noon-one variety daily; and if there is a special tendency to consti- pation, stewed prunes or baked apples may be allowed with the dinner, but not on the days on which they have been used earlier. Oranges, baked apples, stewed prunes, peaches, pears, grapes without seeds or skins; ripe apples (the softer varieties may be given; those known by the dealers as "hard" apples are not suitable unless cooked) are the most suitable. Dinner.-Bread and butter as desired every day- not to be eaten to the exclusion of other foods, how- ever. One soup each day. Bouillon, beef, veal, mutton, chicken, or oyster-broth, which may be thickened with barley or other cereals (either grain or flour). Milk and cream may be added where desirable. One meat daily-roasted or broiled. Beefsteak, beef, lamb or mutton chop, rare roast beef or mutton, chicken (white meat) or roast turkey. Two vegetables daily-one green vegetable and one other dish, usually potato in some form, should be given. Potatoes, baked or mashed, cauliflower tops, asparagus tips, stewed celery, spinach, hominy, plain macaroni, mashed peas, young string-beans, and almost any green vegetable in season. Dessert.-Junket is the best and may be given most frequently, but rice- and milk-pudding, plain custard and plain tapioca-pudding may also be used in small quantities. Ice cream once a week. Fruit in some cases may be used. THE FEEDING OF INFANTS AND CHILDREN. 163 Supper.-Very light simple suppers should be given every day. Milk, milk-toast, bread and butter, and, for older children, a little stewed fruit or baked apple with- out too much sugar. Articles Forbidden (after Holt).-The following articles should not be allowed children under four years of age, and with few exceptions they may be withheld with advantage up to the seventh year. Meats.-Ham, sausage, pork in all forms, salted fish, corned beef, dried beef, goose, game, kidney, liver, bacon, meat-stews, and dressing from roasted meats. Vegetables.-Fried vegetables of all varieties, cabbage, potatoes (except when boiled or roasted), raw or fried onions, raw celery, radishes, lettuce, cucumbers, toma- toes (raw or cooked), beets, egg-plant, and green corn. Bread and Cake.-All hot bread and rolls; buckwheat and all other griddle cakes; all sweet cakes, particularly those containing dried fruits and those heavily frosted. Desserts.-All nuts, candies, pies, tarts, and pastry of every description; also salads, jellies, syrups, and pre- serves. Drinks.-Tea, coffee, wine, beer, and cider. Fruits.-All dried, canned, and preserved fruits; bananas; all fruits out of season and stale fruits, par- ticularly in summer. The meals should be given at fixed hours, which prac- tice should be strictly adhered to. Feeding between meals, even when consisting of the most trifling things, should be avoided. If the child cannot go from one meal to another without discomfort, the intervals should be shortened. In certain cases it may be advisable to give a small cup of milk or broth and a cracker between the meals, at stated intervals, as in feeding younger chil- dren. 164 DIETETICS FOR NURSES. Candies, cake, and the like should be kept from young children. In well-regulated homes, if he once learns that he can not have them, the child will soon cease to demand sweets. The frequent indulgence in sweets of various kinds creates a desire for them to the ex- clusion of other food. This craving is analogous to that for alcohol in adults. Overindulgence in sweets causes indigestion, headache, and the like, ailments that may easily be prevented. The child should be taught to eat slowly and to chew the food well. To this end, some older individual should always be present at meal-time to see that sufficient time be taken for the meal, and that the food be finely divided, as young children do not, as a rule, chew very well. The quantity given to a healthy child should depend on his appetite. In sick children this is not a reliable guide, and where possible fixed amounts may be given. The child should not be forced to eat, nor should he be given special articles to tempt the appetite. If the food offered is not taken, it is well to wait until the next meal, when it will generally be found that the appetite has returned. Loss of appetite is often merely an indication that the digestive organs require a slight rest. During the heated portions of the year the child will require less solid and more liquid food. The same is true during sickness. Many of the gastro-intestinal dis- turbances attributed to teething are the result of improper feeding. Forced Feeding.-Sometimes in cases of loss of weight, malnutrition, and various nervous conditions, it is necessary to put the child to bed and undergo a period of forced feeding similar to that used in grown people. The following is an actual diet list used in such a case: THE FEEDING OF INFANTS AND CHILDREN. 165 Forced Feeding For a Child About Nine Years Old.- 7 A. M.-One egg in orange juice, 4 oz., small quantity of sugar or flavored with lemon juice, well beaten to- gether. 9.30 A. m.-Small quantity of cereal, varied as to kind, 3 slices bacon crisped, 1 or 2 small slices toast, milk and cream (milk 1 qt. and cream 16 per cent.), 8 to 10 oz. 11.30 A. M.-Milk and cream (same proportion), 10 oz. 1.30 p. m.-Broiled squab, asparagus tips or cauli- flower, roast beef, baked potato; or lamb chops, boiled spinach (put through meat chopper); or breast of chicken, rice, carrots (mashed); ice cream or custard or rice pud- ding or junket. Select one vegetable for each day with the baked potato or rice. Milk and cream (same pro- portion), 10 oz. 4 p. M.-Milk and cream (same proportion), 10 oz. 6.30 P. M.-Sandwiches-bacon or chicken, calves' foot jelly, wine jelly, apple sauce, baked apples, prunes, apricots, toast (plain), milk, 10 oz. Patient nine years old having this diet for four weeks gained 7 pounds. No vomiting or any symptoms of being unable to digest this quantity. Patient had been eating poorly at family table, but after three or four days took this diet without any urging at all. Reduce or omit cream if patient has symptoms of nausea or any other symptoms of not being able to digest this quantity. Water, 34 to 36 oz., given at intervals between feedings. The period usually spoken of as " school days " is an extremely active one physically. The vast number of metabolic changes going on and the growth of the body demand a plentiful and a suitable diet Both in and out of school and in seminaries careful attention should be DIET OF SCHOOL CHILDREN. 166 DIETETICS FOR NURSES. given to food, fresh air, and exercise. In other words, the physical development should receive as much atten- tion as the mental growth. In boarding-schools espe- cially the diet should be the subject of careful study, the aim being to avoid monotony and to provide a sufficient and satisfying diet. In many schools the dietary is left to the discretion of the cook. In considering school dietaries several points are worthy of consideration. Milk, being easily digested in most cases, is of great value, especially for children whose nutrition is below normal. It should be furnished as a beverage daily for breakfast and supper, and is advisable even with dinner. It may also be used in the preparation of puddings and soups. Cream is very valuable, and whenever possible should be supplied in sufficient quantities. A cup of warm milk with bread or crackers is helpful during the middle of the morning and as a substitute for tea in the afternoon. Delicate children and others may with advan- tage take a glass of warm milk a short time before going to bed. If the rising hour is some time before that set for breakfast, a cup of milk or of bread and milk should be given on rising. Eggs may be used alone or in the preparation of vari- ous dishes. They may be used in almost any way except fried. Fried eggs are apt to be very indigestible. They are often prepared in this way in order to disguise the stale taste of an egg that has been in storage for some time. Meat is a very important part of the diet, as it con- tains a larger quantity of protein, from which the tissues are built up, and in a more available form, than in any other form of food. Milk and eggs are also valuable sources of protein. Meat should be provided, therefore, in suffi- THE FEEDING OF INFANTS AND CHILDREN. 167 cient quantities, a half-pound a day being, perhaps, a good average allowance for a growing boy, the larger and more robust taking that quantity or more, the smaller and more delicate children taking somewhat less. Steak, chops, and roasts of beef, mutton, lamb, fowl, and bacon are the most suitable meats, although pork, together with meat-stews, meat-puddings, sausage, and hashes, may be allowed in smaller quantities. These last, while generally relished, are not so digestible nor such good sources of nutriment as those first named. With care and proper preparation many of their ill effects can be obviated. More meat is required in winter than in sum- mer, and more in cold climates than in warm. Yeo states that too much meat may give rise to eczema. Meat may be given twice a day, and eggs or fresh fish may be substituted for it about three times a week. When these do not satisfy the appetite, meat may be added. For this purpose cold sliced meat is useful. Bread and butter should be given with each meal. Bread made from the whole-wheat flour may be used in the largest quantity, but it is well to supply various kinds of bread, to avoid monotony. " Brown bread " given continuously becomes very tiresome. Rye-bread may be given occasionally, and bread made from mixtures of wheat and rye is very palatable. Rusk, biscuit, and crackers may also be supplied. Corn-bread, when prop- erly made, may be given once a week or oftener, and griddle cakes of buckwheat, corn, or wheat flour two or three times a week. These last may be served with syrup or fruit-juices. Cereal porridges of all kinds may be given for break- fast, oatmeal being probably the most desirable. Vegetables of almost all varieties may be used. For 168 DIETETICS FOR NURSES. dinner two varieties should be given, one green vegetable and potatoes. Salads made of the green vegetables, with the very simplest dressings, are useful additions to the diet. Fruit should invariably be given once a day. Sugar should be provided for in the dietary. Candies and many of the sweets given to children are harmful and cause indigestion and dyspepsia. If proper sweets were provided there would be slighter tendency to indulge in the less desirable forms whenever opportunity offered. With the meals, and when the appetite demands satisfy- ing between meals, they may be given with or without a glass of milk. Regularity should, however, be ob- served, and they should not be given immediately before or after a meal. Fruit-syrups, sugar-syrups, honey, pre- served fruits, and jam may be eaten with bread. Cara- mels, chocolate, maple-sugar, and plain sugar-taffies are the best of the other forms of sweets. Simple desserts, such as custards, milk-pudding with rice, tapioca and the like, bread-pudding, plain cakes, and properly prepared pastry may be used. The beverages should be water and milk. Weak cocoa or chocolate may be given after the seventh year. Tea and coffee should not be given before the thirteenth year, and may be withheld advantageously still longer. Alco- hol is not to be used except by a physician's direction. Especial care should be taken to avoid a monotonous diet, for there are many instances where the constant repetition of a certain form of food has created a dislike for it that has persisted throughout life or been overcome only with difficulty. A second point to be remembered is that the food should be well prepared and attractively served. This THE FEEDING OF INFANTS AND CHILDREN. 169 has more to do with influencing the appetite of delicate, nervous children than is generally supposed, and can not be insisted upon too strongly. Overeating should be avoided, and to this end an older person should always be present when practicable; in school, this should be insisted upon. On the other hand, a child should not, through caprice or habit, be allowed to eat too little. By exercising a little tact, most of the dislikes which are not deeply rooted, but which may become so if persisted in, may generally be over- come. These dislikes are often the result of imitation. Sufficient time should be allowed not only for the meal, but for the performance of whatever small duties may be required of the child. A time should be set for one or two regular daily visits to the water-closet. Hur- rying to school should be avoided. Reading and study- ing immediately before and after meals should be pro- hibited, as should bathing or any very active exercise. Some light form of recreation may, however, be indulged in. The hours of meals should be so arranged that the child may have freshly prepared meals, and not cold luncheons or warmed-over dinners. Lastly, nibbling and eating between meals, except under the conditions pre- viously described, should be strictly prohibited. In spite of stringent rules, however, many infringements will occur. It is by neglect of the diet, fresh air, and exercise that many cases of tuberculosis gain headway; anemia may result from such neglect, and a delicate, nervous child be the outcome of one that should, by right, be healthy. FEEDING IN INFANT ASYLUMS. The feeding of infants in overcrowded infant asylums, with their lack of fresh air and paucity of attendants, is 170 DIETETICS FOR NURSES. a matter of great difficulty. Any attempt at scientific feeding under such circumstances will ultimately lead to failure, the method in these cases being held to blame. The primary cause of malnutrition and marasmus in in- stitutions is the lack of fresh air and individual care, and until these are obtainable it is useless to attempt to ac- complish anything by special feeding methods. In the smaller institutions the use of the Materna graduate will be found satisfactory. In the larger asylums it is well to have two or three general working formulas, such as fat 3 per cent., sugar 6 per cent., protein 1 per cent.; and fat 4 per cent., sugar 7 per cent., protein 2 per cent. These may be varied by adding more or less water to them to adapt them more closely to special needs. The younger infants may, when possible, receive special mixtures. For substitute feeding, condensed milk, barley- and egg-water will be found most useful. The allowance of a few cents a day generally made for an infant's entire care is entirely inadequate to accom- plish any good. CHAPTER V. THE FEEDING OF SICK INFANTS. Finkelstein's Classification.-This is largely used by some writers: i. Disturbed metabolic balance corresponding to our stationary weight and loss of weight. 2. Dyspepsia corresponding to gastro-intestinal in- digestion. 3. Intoxication corresponding to acute severe diarrhea. 4. Decomposition corresponding to marasmus. Stationary Weight; toss of Weight.-The best index of nutrition is the weight of the child. If there is a stationary weight or the child loses weight the phys- ician should be informed at once, as it may mean serious trouble. Not infrequently this condition is due to a too high fat content in the food. The baby becomes pale, irritable, and sleeps poorly. Some gas, some vomiting or spitting, and hard dry stools which may be shaken from the napkin are noted. In the beginning there may only be hard, white, sand-like particles in the stool, later the stools become discolored and contain mucus. Withdrawing the fat and feeding skimmed milk, protein milk, or buttermilk, gradually returning to as near a normal diet as possible, usually gives good re- sults. The addition of carbohydrates and the use of malt sugar is also advised. Colic.-This is more frequent in breast-fed than in artificially fed children, and is most liable to occur dur- ing the first three months. In breast-fed children it may 171 172 DIETETICS FOR NURSES. sometimes be due to the mother's milk being too rich, and measures are frequently prescribed to relieve this. The nursing intervals may be lengthened, and a little warm water given before each feeding to dilute the milk. In bottle-fed babies colic is most frequently due to the milk containing too much protein. It may also be caused by giving the milk too cold. Colic may be due to cold feet, chilling of the abdomen, and numerous other causes which have no relation to the diet. The addition of a small amount of calcium caseinate to the food sometimes is useful. Vomiting'.-Vomiting occurring immediately after feeding is usually due to the child's taking too much food or the taking it too rapidly. Vomiting may be caused at any time by the abdominal binder being too tight, from shaking the infant or holding with the head over the nurse's shoulder, or from patting on the back. Vomiting may occur at any time when the milk is too rich in proteins. It may be caused by coughing, and it is also a frequent symptom of many diseases. Vomiting one or two hours after feeding is usually due to the milk containing either too much fat or too much sugar, or both. Milk boiled with sufficient barley flour or other cereal to make a thick gruel, given with a spoon, will often be retained where thin fluids are rejected. Gavage.-Gavage, or feeding by means of a stomach- tube, is a method used in various diseases and conditions of infancy and childhood. In cases where the child is not able to take nourishment, or only in insufficient amount, and in cases of uncontrollable vomiting, this method may be resorted to. It is used in the feeding of premature infants, whether in an incubator or not, and in cases of small, weak, marantic infants who, owing to weakness or lack of appetite, do not take sufficient nour- THE FEEDING OF SICK INFANTS. 173 ishment. It is also employed after surgical operations about the head or neck where swallowing is interfered with, and in acute diseases, such as pneumonia, in fevers, and in delirium or coma. The results that follow this method of feeding are surprising, especially in cases where there is constant vomiting or where the stomach has a very small capacity. In the former case, the vomiting may cease and the food be retained; in the latter, the capacity of a stomach that previously held only an ounce or two may rapidly be increased until an average-sized feeding is retained with ease. The technic of the method is simple and the procedure conducted without difficulty in children under two years of age; above that age it may be difficult, and a mouth- gag may be required; in some cases nasal feeding must be substituted. The apparatus employed is the same that is used for washing out the stomach; and since it is frequently desirable to wash out the stomach before in- troducing the meal, the same tubing may serve for both purposes. It consists of a soft-rubber catheter, con- nected by means of a piece of glass tubing to a piece of rubber tubing, to the other end of which a funnel is attached. The nurse holds the child in her lap, with the head held straight and not inclined in either direction. The catheter is moistened with warm water and held several inches from the end, so as to allow enough of it to pass into the esophagus with the first attempt at intro- duction. The mouth is opened, if necessary, and the catheter passed rapidly into the pharynx; there is usually a swallowing movement, and the tube is readily passed into the stomach. If the procedure is carried on too slowly the tongue may interfere; or if the catheter is 174 DIETETICS FOR NURSES. held too near the end, it may cause gagging. Before in- troducing the food it is well to wash out the stomach with normal salt solution. As soon as all the food has entered the stomach, the catheter is pinched and rapidly withdrawn. If it is withdrawn slowly the food may come up with the tube. If the catheter is left open as it is withdrawn, the dripping into the pharynx may cause vomiting. If the child is young, it is a good plan to keep the finger between the jaws for a few moments, to prevent gagging. If the food comes up the feeding must be repeated. Nasal Feeding.-For this purpose a catheter in proportion to the size of the child should be used. The procedure is the same as that for adults. Feeding in Inflammations of the Mouth.-The food should be liquid or semisolid, and as bland and unirritating as possible. If it is not taken readily it should be given cold. Diseases of the Stomach.-Where there is marked vomiting and evidence of disease of the stomach milk should be withheld, and the patient given plain boiled water or albumin water in small quantities until the physician gives his orders concerning the feeding. Cyclic Vomiting-Acid Intoxication.-This is not an uncommon disturbance of metabolism, in which there is a formation of acids in the body which cause re- current attacks of vomiting. During the attack it is well to give the stomach absolute rest, as both food and drink tend to aggravate the condition. Glucose solutions are administered as detailed in the section on Acidosis. See Acidosis. When the vomiting stops, the feeding may be begun very cautiously. Skimmed milk, to which citrate of soda or lime-water has been added, or peptonized milk or albumen-water or barley-water may THE FEEDING OF SICK INFANTS. 175 be given to begin with, and the diet increased as circum- stances warrant. Between the attacks the question of the diet is a very important one. Sometimes it requires con- siderable study on the part of the physician to determine what may be allowed and what withheld, but in most cases these patients do best on a diet of milk, eggs, green vegetables, bread, cereals, with the sweets almost entirely eliminated from the dietary. All cases are not alike, how- ever, and various other forms of diet may be prescribed. Diarrhea in Infancy and Childhood.-In a child under two and, indeed, even in older children, one can never say at the outset whether a diarrhea will be mild or severe. It is therefore well to diet all cases as if they were of a virulent type. By so doing many lives will be saved and much suffering avoided. About 97 per cent, of the deaths from diarrhea occur in bottle-fed babies, and the majority of these in the hot weather. In breast-fed children a diarrhea in winter is usually a mild one, and merely lengthening the nursing periods to six hours and giving barley, rice, or albumin water in the intervals at the feeding times is all that is needed. After a day or two of this, together with the proper medical treatment, the child can generally resume its customary schedule. In summer, however, a diarrhea, especially if severe, should arouse suspicion, and for twenty-four hours, or until the child's condition warrants, milk should be with- held. The breasts should be pumped out carefully at regular intervals, to prevent distress or a possible cessa- tion of the secretion. The child should be given plain boiled water, or some of the articles previously men- tioned, at frequent intervals and in small doses. If there is great thirst, one or two teaspoonfuls should be given 176 DIETETICS FOR NURSES. every fifteen or thirty minutes. If fluid is well retained, several ounces may be given at a time, at intervals of two or three hours. Stimulants are often ordered. If by the second day vomiting has ceased and the child seems better, it may be put to the breast for a few min- utes and the effect noted. If the milk is well borne the child may be given the breast every six hours, shortening the interval from time to time until the child has re- turned to its regular schedule. It is well to make a gradual return, and if the milk aggravates the diarrhea or gives rise to other symptoms, it should again be dis- continued. When the breast milk is of good quality there is rarely any difficulty with these cases. In infants partly on the breast and partly on the bottle the diet should be planned so that it will be satisfactory should the case be one of a serious nature. For the first twenty-four hours plain water, barley-water, or very weak tea. At the end of twenty-four hours if there is no vomiting a partly breast-fed child may usually be allowed to take breast milk at the usual feeding intervals with water before the feeding and the nursing increased according to the condition of the stools. A mistake which is usually made is not to starve the child boldly during the first twenty-four hours, and the second is to starve it too long. In bottle-fed babies the method of feeding will vary according to the nature and severity of the diarrhea. Relatively fat-free foods should always be used. The child should be starved for the first twenty-four hours as above, or given a small amount of weak tea or plain water. In cases in which there is fermentation and gas the use of protein milk or one of its modifications gives very good results. On this food the stools usually change to the so-called soap stools, and when this happens THE FEEDING OF SICK INFANTS. 177 some form of carbohydrate, usually in the form of dextri- maltose, may be added, and later barley or some other cereal gruel. The protein milk as suggested by Finkel- stein is made as follows: Heat i quart of whole milk to ioo° F. (36.66° C.), add 4 teaspoonfuls of essence of pepsin, and stir. Then let the mixture stand at ioo° F. until the curd has formed. Put the mass in a linen cloth and strain the whey from the curd. Remove the curd from the cloth and press it through a fine sieve two or three times, using a wooden mallet or spoon. While doing this 1 pint of water should be added. The precipitate should be very finely divided and the mixture should look like milk. For those who cannot afford casein milk, Reuben sug- gests the following: Add two junket tablets to a pint of milk. After it has stood for one-half hour strain, discard the whey, and rub the curd through a fine sieve together with a pint of milk, and then add enough plain boiled water to make one quart (1.14 liter). The whole mixture is then brought to a boil with constant stirring and is then ready for use. This has nearly the value of casein, but lacks the acidity, a point which does not seem to be essential. As a rule we prefer skimmed milk mixtures to which calcium caseinate has been added in the proportion usually of ounce (10 grams) to a pint (0.57 liter). The proportion of skimmed milk may be varied to suit the patient, but ordinarily half milk and half water with the calcium caseinate added and then boiled five min- utes gives a satisfactory mixture. It should be stirred constantly while being heated. If the calcium caseinate is mixed in about one-third of the mixture while cold and 178 DIETETICS FOR NURSES. the remainder of the milk heated and then cold solution poured into the hot milk and boiled, a smooth mixture will result. This should be used after the manner of protein milk, that is, start with very small amounts, i to 4 drams, for instance, and double the size of the feeding each time, providing this amount is retained. This feeding is starvation diet, and as soon as possible other food should be added. Old fashioned buttermilk, that is, the milk left after churning butter or a similarly made preparation, may also be used either diluted with water or with barley-water. Ordinarily the dilutions are made half and half to begin with and stronger as the child improves. In cases where there is putrefaction or foul stools and where the child is losing fluid rapidly from the tissues, the cereal gruels, such as barley or rice gruels, give excellent results in the beginning, or this may be replaced with mixtures containing dextrimaltose, starting with i level tablepoonful to 4 ounces of water, and giving a teaspoonful at a dose, and then increasing. Sweetened condensed milk or malted milk also are use- ful in this form of diarrhea. The management of the diet of a case of diarrhea requires more judgment than almost anything in pediatric practice. In place of plain water a little thin barley-water or a little very weak tea may be given. At the end of twenty- four hours, if the stomach and bowel have been thoroughly emptied and given a rest and there is no vomiting, an increase may be made in the food. An error which is ordinarily made is to fail to starve the child boldly during the first twenty-four hours, and the second error is to starve it too long. The proper feeding in severe diarrhea is a difficult question and one about which there is a great deal of THE FEEDING OF SICK INFANTS. 179 difference of opinion. The truth of the matter is that we do not know sufficiently about the feeding of these cases to speak very dogmatically concerning them. The authors believe that the only food component which should be avoided in all cases is fat. Children with diarrhea certainly do better on either fat-free or foods relatively low in fat. In cases where there is much fermentation and gas, protein milk or one of its modifications may be used. For those who cannot afford protein milk Reuben sug- gests the following: Add two junket tablets to a pint of milk. After it has stood for one-half hour, strain, discard the whey, and rub the curd through a fine sieve together with a pint of milk, and then add enough plain boiled water to make one quart (i .14 liter). The whole mixture is then brought to a boil, with constant stirring, and is then ready for use. This has nearly the value of casein milk, but lacks the acidity, a point which does not seem to be essential. The authors prefer skimmed milk mixtures to which calcium caseinate has been added in the proportion usually of one-third of an ounce to a pint. The pro- portion of skimmed milk may be varied to suit the pa- tient, but ordinarily half milk and half water with the calcium caseinate added and then boiled five minutes gives a satisfactory mixture. If the calcium caseinate is dissolved in about one-third of the mixture while cold and the remainder of the solution heated and then cold milk poured into the hot milk and boiled, a smooth mixture will result. This should be used after the manner of protein milk, that is, start with very small amounts, and double the size of the feeding each time, providing this amount is retained. 180 DIETETICS FOR NURSES. The character of the stools should change to the so- called soap stools, and when this happens some form of carbohydrate should be added to increase the caloric value of the food. Sugar is usually added, begin- ning at I per cent., or dextrimaltose may be used, and later barley gruel may take the place of the plain water. It should be remembered that protein milk feeding is starvation diet, and as soon as the stomach and intes- tinal tract will stand it the food should be increased to cover the needs of the child in question. Old-fashioned buttermilk, that is, milk left after churning butter, is a most useful food either diluted with water or with barley-water, half and half, and given in the same way as protein milk. With foul stools and where the child is losing fluid rapidly from the tissues, cereal gruels, such as barley gruel or rice gruel, may be used to advantage. These are usually made in the proportion of one level table- spoonful of flour to a pint of water and a pinch of salt and the mixture is boiled for fifteen minutes. This may be sweetened a little either with saccharin or with dextrimaltose. After a day or two the skimmed boiled milk or one of the dry milks may be added to this, a level tablespoonful of either of the dry milks being used to 4 ounces of gruel, and then increased until it is either in the proportion of 3 tablespoonfuls to 4 ounces or in some instances in older children 4 tablespoonfuls to 4 ounces. In some putrefaction cases large doses of dextrimaltose or of lactose are sometimes advised. Their use requires rather nice judgment, and harm may result if used in unsuitable cases. In some instances malted milk is useful in the strength of 1 level teaspoonful to an ounce, or weaker, to begin with. THE FEEDING OF SICK INFANTS. 181 The return to milk should be made very gradually. In the severe cases cows' milk should be withheld for a week, when, if the child's condition permits, it may be tried in one small feeding. If it causes no trouble, it may grad- ually be added until the usual diet is resumed. The re- turn is best made by allowing the articles previously sug- gested. Then malted milk, or one of the dry foods that is to be mixed with water, may be given, followed by par- tially or wholly peptonized milk or the barley water and milk mixture previously described. Plain well-skimmed meat broths, such as veal broth, may be used. Care must be taken to remove all the fat, as this is a frequent source of trouble. The milk should not at first contain too great a percentage of fat. This bold starvation plan, as it is sometimes called, succeeds better than any other. Later, however, care must be taken that the periods of underfeeding be not too protracted, for while it is desir- able to " starve out the diarrhea," the child must not be starved to death during the process. A day or two of absolute abstinence from food does no harm, as in the severe cases food is not retained, or if retained, is not assimilated; on the other hand, a reduced diet continued for weeks and months, as is not infrequently done, is apt to prove disastrous. It is a good plan to keep an accu- rate record of all the food taken while the child is on a restricted diet. The amounts taken during each twenty- four hours may be added together, and from these it may readily be seen whether or not the child is getting sufficient nourishment. Another plan of treatment much in vogue at the pres- ent time is to give the child buttermilk from the outset, or kumiss, or some other similar preparation, or if these are not well borne, to give lactic acid bacilli, either in 182 DIETETICS FOR NURSES. the tablet form or the liquid cultures, and when this is done cows' milk or one of the dried milk preparations, such as Mammala, can be given with safety. Diarrhea in Older Children.-When diarrhea oc- curs in older children, the early dietetic treatment is similar to that recommended for infants. As the child recovers a return to the ordinary diet may be made, meat, eggs, and broths of various kinds being given at first, followed by boiled milk and toast or dry bread. Vegetables and fruits should be given only after recov- ery is complete, and their effect should carefully be watched. Cereals may also cause a recurrence of the trouble, and should be most thoroughly cooked and given in small quantities at first. Chronic Intestinal Indigestion.-The diet in this disease will always be carefully outlined by the physi- cian, and it is of the greatest importance to see that the directions are carried out. The disease is often pro- tracted, and requires months or even a year or two of careful dieting to relieve the condition. The carbohy- drate foods are usually reduced to a minimum and easily digestible proteins given. Slight indiscretions in diet fre- quently lead to relapses in which all the ground gained in several months is lost by a single improper meal. Constipation.-This is frequently difficult to over- come. Fruit juice given on an empty stomach an hour before a milk-feeding is of service, as are olive oil and cream. These latter must not be used indiscriminately, as they may give rise to other bowel trouble if given in too large quantities. The malted foods, such as Mellin's, are useful; mixed with milk or oatmeal gruel well sweet- ened they may relieve it. Infants are sometimes re- lieved by adding oat flour gruel or barley gruel to the food. After seven months vegetables put through a THE FEEDING OF SICK INFANTS. 183 sieve may be given-carrots, spinach, lettuce, celery, and the like. Cut up a quantity of various vegetables into small cubes, add salt and boil until soft, skim but do not strain, cook until a mush results. Now strain and add from a teaspoonful to 2 tablespoonfuls to the diet either alone or in broth. In older children figs and prunes stewed together are of value; oatmeal and bread from unbolted flour may be used. A glassful of water given on rising is sometimes of assistance. Green vege- tables, especially of the coarser sort, are useful, as are the agar, toasted bran, graham, and oatmeal crackers. Wasting Disease.-The diet is of primary impor- tance, but fresh air and exercise and warmth must not be overlooked. The infant should in all cases be fed in the nurse's arms and never in its crib. The diet is pre- scribed by the physician. Rickets or Rachitis.-This is a disease of nutrition in which insufficient calcium is deposited in the bones. It is most frequently seen in the temperate zone, in artificially fed children who do not get sufficient light and air. Diets low in fats and proteins and rich in carbohydrates cause rickets. (See Vitamins.) There is a calcium-depositing vitamin the absence of which will cause rickets when there is a deficiency of either calcium or phosphorus, or both. Rickets is prevented by fresh air, sunlight, good hygiene and a proper diet, also by giving cod-liver oil, especially phosphorized cod-liver oil. The same measures will effect a cure if started sufficiently early. CHAPTER VI. DIET FOR THE AGED. When a man has passed his fiftieth year his diet should be guarded. Dietary indiscretions or a too plentiful diet will result either in the putting on of flesh, and the con- sequent discomforts of obesity, or in the development of gout or allied affections. In considering the diet of the aged the old dictum, that a man is as old as his arteries, applies. Age can not always be counted by years. In the aged there is a lessening of all physical activities. The old man takes less exercise, has diminished powers of digestion, and is less able to absorb the nutriment he has digested. His circulation is poor and his bowels are constipated. Degenerative processes have taken place in his organs, and he is more apt to feel the effects of indiscretions in diet. For these reasons the diet should be lighter than in his younger years, and the amount of food eaten should vary with the needs of the individual. The food should be of an easily digestible variety; it should be given in smaller quantities at a time and the intervals between meals should be shortened. If there is a tendency to obesity, food that is liable to be con- verted into fat should be given in diminished amounts. The proteins should be somewhat lessened from time to time. The practice of eating heavy suppers late at night and of eating between meals should be discontinued. The person should learn what particular articles of food disagree with him, and refrain from eating foods that tend 184 DIET FOR THE AGED. 185 to cause flatulence. Yeo suggests that in the case of cooked fruits a small quantity (about a teaspoonful to the pound of fruit) of sodium bicarbonate be stewed with them, to correct the acidity that causes flatulence. In the aged, food bears a close relation to sleep. A cupful of hot milk, hot toddy, or some hot liquid food taken at bedtime will often overcome troublesome sleep- lessness. A few sips of milk or a mild stimulant taken during the early morning hours, when the aged are apt to awaken, will frequently insure sleep again. Food Suitable for the Aged (Yeo).-Young and tender chicken and game and other tender meats; potted chicken, game, and other potted meats; sweet- breads ; white fish, as sole, whiting, smelts, flounder, etc., best when boiled; bacon grilled; eggs lightly cooked, or beaten up with milk, etc.; nutritious soups, such as chicken or fish purees, beef tea, mutton and chicken broths; milk in all forms when easily digested. When it is not well borne, the addition of an equal quantity of warm Vichy or of warm water will often prove helpful. Beef tea and milk supply the needed mineral substance, and the former is an excellent stimulant. The following foods are all suitable: Bread-and-milk with the crumbs of stale bread and without lumps; por- ridge and oatmeal gruel; puddings of ground rice, tapi- oca, arrowroot, sago, macaroni, with milk or eggs, and flavored with spices or served with fruit juice or jelly; bread and butter, the bread to be at least a day old; rusk, to be soaked in tea or milk and water. Prepared foods, consisting of predigested starches; at this age the digestive ferments are provided scantily by the digestive organs, and soluble carbohydrates are valuable for main- taining the body heat. All farinaceous foods should be 186 DIETETICS FOR NURSES. subjected to a high temperature for some time during the cooking process so as to render the starch granules more digestible. Vegetable purees of all kinds may be taken in moder- ation-e. g., potatoes, carrots, spinach, and other succu- lent vegetables. Potatoes and fresh vegetables are a necessity; if omitted a scorbutic state may be engen- dered. Stewed celery and stewed Spanish or Portugal onions lend variety to the diet. Stewed or baked fruits, fruit jellies, and the pulp of perfectly ripe raw fruits in small quantity may be taken. CHAPTER VIL DIET DURING PREGNANCY AND THE PUER- PERIUM. During1 Pregnancy.-The diet should be that to which the patient has been accustomed. There is often craving for unusual articles of diet, and these cravings should not be gratified. Sometimes a diet somewhat deficient in carbohydrates and fluids is advised with the idea of producing a small child, a thing desirable when there are contractions of the pelvis and a difficult labor is expected. Diet During the Puerperium.-Formerly great restrictions were placed on the diet of a recently deliv- ered woman, thus accounting, in part, for the loss of weight that has been noted. If there is no nausea and the patient desires it, a cupful of tea or a glassful of warm milk may be given soon after delivery. The appetite is generally poor for a few days after delivery, but food should be given at regular intervals not too widely separated. The first day milk, milk toast, or if desired, dry or buttered toast, with coffee, tea, or cocoa, according to the taste of the patient, may be given. Water may be allowed as desired. On the sec- ond and third days simple soups or any of the following may be added to the dietary: Meat broths, beef tea, soft-boiled or poached eggs, raw or stewed oysters, and some simple dessert, such as wine jelly, boiled custard, 187 188 DIETETICS FOR NURSES. or junket. During the next few days chicken, scraped beef or mutton in small quantities, baked potato, rice, and cereals may be given, and by the end of the week a gradual return to the ordinary diet may be made. Diet in the Diseases of Pregnancy.-Special diets are sometimes ordered the pregnant woman on account of diseases connected with her pregnancy. Sometimes a milk diet or a diet similar to that used in inflammation of the kidneys is used. When salivation occurs a milk diet is used. Rectal feeding is used when there is uncontrollable vomiting. CHAPTER VIII. RECTAL FEEDING. When the patient cannot take food by the mouth, or when it is not desirable to feed him in that way, rectal feeding is resorted to. All the various classes of foods may be used for this purpose. Proteins are supplied in the form of predigested meat or egg albumin to which salt has been added. Nutrose and peptones are also used. Grape sugar and starch are sometimes employed. Fat is given in the form of the yolk of egg or cream. Milk is also much used. Where the patient is to be fed by the rectum for any length of time, combinations of these are used as suggested in the formulas given below. Bauer believes that but one-fourth of the nutriment needed by the body can be absorbed by the rectum, and both he and the earlier writers placed the length of time which rectal feeding was practicable at from one to two weeks. With careful technique, this period may be ex- tended from four to six weeks, depending on the capacity of the individual for continued absorption, and on the amount of energy stored up in his body at the beginning of the rectal feeding; but von Leube has kept a patient alive for six months, and Riegel for ten months on exclu- sive rectal feeding. As a rule, however, as only about one-fourth, and often even less, of the amount of nutri- ment needed can be absorbed, the method is only useful in protecting the body from excessive loss during periods of partial or complete starvation. 189 190 DIETETICS FOR NURSES. The success of rectal feeding depends on the proper technic. With poor technic the rectum soon becomes irritable. Procedure.-The rectum should be cleansed thor- oughly by administering a high injection of normal salt solution one hour before the enema is to be given. This cleansing should be practised at least once a day, and if much mucus is present it may be well to precede each feeding by a cleansing enema. If the rectum is inflamed a solution of boric acid may be used instead of the salt solution; or if there is much mucus a solution of sodium bicarbonate may be employed, a teaspoonful of either to the pint of water being sufficient. For the first one or two cleansing enemata the bowel should be flushed by the ordinary method; later, a return-flow catheter may be used; with this several quarts of solution may be used; without it one-half to a pint will be sufficient in most cases. The temperature of the cleansing enemata should be between 95 ° and 990 F.; that of the enemata which are to be retained between 900 and 950 F. Solutions that are too hot or too cold will promptly be rejected. The position of the patient is very important. He should lie on his side, with the hips well elevated. On account of disease this position may be impracticable. In this case the foot of the bed may be raised and pillows placed under the hips, to make as much elevation as possible. A rectal tube or a large catheter should be used. This should not, however, be too large; a tube 1 cm. (about | inch or less) being the proper size for an adult. For children the tube should be proportionately smaller. It should be lubricated thoroughly, but glycerin should not be used for this purpose. In introducing the tube it should be twisted slightly, RECTAL FEEDING. 191 which lessens the liability of its becoming impacted in the rectal folds. If it is not passed easily a small quan- tity of fluid should be allowed to flow in, which will serve to balloon out the rectum, after which the tube may usually be passed with ease for 8 or io inches or more. The tube should in all cases be introduced as high up as possible, as the enema is thus more likely to be retained and absorbed. The fluid should be allowed to flow in slowly from a funnel or a fountain-syringe. In some instances, where very small injections are being used, a small hard-rubber syringe may be attached to the tube. Care should be taken to avoid injecting air with the fluid. The method of administering nutrient enemata by means of the old- fashioned short hard-rubber nozzle of either a piston or a Davidson syringe can not be too strongly condemned. In the hands of the unskilful it may cause injury to the rectum, and even if used by a trained nurse, only suc- ceeds in placing the fluid in the lower part of the rectum, where it is liable to be expelled. After the injection the patient should lie as quietly as possible for at least an hour, and be instructed to try to retain the contents of the bowel. A pad of gauze or a towel should be pressed over the anus for twenty minutes or half an hour, and the mind should, if possible, be diverted from the subject. After a few days the bowel often acquires a tolerance for the injections and they may be retained without difficulty. If the rectum is irritable and the fluid rejected, the physician may order the nurse to precede the nutrient enemata by a small suppository containing opium, or, what is better, a small rectal injection of the tincture of 192 DIETETICS FOR NURSES. opium may be given. This may be mixed with a little starch water, but the whole should be as small as pos- sible. The opium should not be used unless necessary, and the dose should be just sufficient to quiet the bowel. The opium may be added directly to the enema. If there are hemorrhoids, rectal feeding will be greatly interfered with. Before each injection they may be painted with a 2 per cent, cocain solution, and between the feedings a soothing ointment should be applied. The amount to be given at each injection is an im- portant factor. As a rule, it should not exceed | liter (| pint). If this be not well borne the amount may be reduced to from 30 to 100 c.c. (1-3 oz.). The number of enemata to be used will depend some- what upon the patient's constitution; as a general rule, five, or better six, hours should be allowed to elapse between each feeding. It is well to remember that packing in the vagina and other gynecologic dressings may interfere materially with the injection of fluid in the bowel. The patient's mouth should be kept very clean, and the patient may be allowed to rinse it from time to time to help allay the thirst, which is usually intense. Under some circumstances water may be taken into the stomach, but where absolute rest of the stomach is indicated, not even that should be allowed. Enemata of weak salt solu- tion may be given to relieve thirst, or salt solution may be given subcutaneously. A part of the good effect of the nutrient enemata is the mental satisfaction following it, similar to that following a meal. The patient having also the feeling that he is not being allowed to starve. Prevention of Parotitis During Rectal Feed- RECTAL FEEDING. 193 ing.-The flow of saliva is encouraged by having the patient chew on a piece of rubber or a piece of chewing gum and the mouth will remain moist and clean and parotitis avoided. Nutrient Enemeta by the Drop Method.-Since Murphy's introduction of continuous protoclysis by the drop method, the administration of nutrient enemata by the same plan has been practised by various clinicians. Eberhard has recently called especial attention to this method of treatment. His apparatus consists of an ordi- nary quart can, inside of which is placed another can holding a pint. These are connected by an 8-inch pipe, which penetrates the bottom of each and projects about 2 inches. A small pet-cock, soldered to the base of the outside, can allow water to be withdrawn at will. Milk and egg or any other nutriment placed in the smaller can is kept warm, and flows freely on account of its being surrounded by hot water. Water at a temperature of no° to 1150 F. seems to answer all purposes. The remainder of the apparatus is the same as used for saline enteroclysis. To insure absorption the bowel must be cleansed by an enema each day. The flow must be regu- lated to about a drop a second. According to Eberhard, in one and a half hours io ounces of milk and 2 raw eggs flow into the bowel. A fairly complete list of nutrient enemata as advised by the older writers will be found in the former editions of this book, and have a historic interest. The following formulae are suggested: 1. Milk, pancreatized for twenty-four hours and boiled, 250 c.c. (8 ounces). 2. To the above may be added any of the following, either alone or in any combination: (a) Dextrose, 5 to 12.5 grams (15-3 drams). DIETETICS FOR NURSES. 194 (&) Alcohol, 5 to 12.5 c.c. (1^-3 drams). (c) Egg yolk, 1 or 2. The drop method is especially indicated in persistent vomiting, in hemorrhages, stenosis of the esophagus or pylorus, in carcinoma of the stomach, and in most conditions in which nutrient enemata are ordinarily em- ployed. At present the best mixtures seem to be normal salt solution to which dextrose and alcohol have been added in the proportion of 5 per cent. Five to 20 drops of tincture of opium are advised by some to be added to a liter during the first day, and it is thought that | grain of thymol per liter will prevent bacterial change in the bowel. A liter of the above contains 550 calories and may be administered in eight hours under favorable conditions. The formula will be: Dextrose, 50 grams (if ounces). Alcohol, 50 grams (if ounces). Normal salt solution, 1000 c.c. (32 ounces). This may be found useful after operations, in acidosis, in diabetic coma, and in many of the indications for rectal enemata. OTHER METHODS OF NOURISHING THE BODY. Duodenal Alimentation.-Einhorn, Morgan, and others, following the suggestion of the first-named inves- tigator, have used a duodenal tube, not only as a matter of diagnosis, but for feeding certain classes of cases. At present the tube has been used in those cases in which it was thought desirable-to rest the stomach-as in cases of persistent vomiting and in certain gastric and duodenal ulcers. The ordinary Einhorn tube is used, and care should be taken to see that it is in place before the feed- RECTAL FEEDING. 195 ing is started. This may be done by gentle traction, which shows a slight resistance if the tube is in the duodenum; by aspiration, which will often bring up golden-yellow duodenal juice without any gastric secre- tion ; or perhaps best, by giving the patient some liquid to drink by mouth and immediately performing aspira- tion. If the end of the tube is in the stomach, the fluid can be removed. Any liquid food may be employed, but mixtures of milk, sugar, and raw eggs are the most useful. Care should be taken to see that there are no particles in the food that might clog the tube. The amount at the beginning should be small, 100 c.c. every two hours, beginning early in the morning and stopping late in the evening. This quantity may be gradually increased up to 300 c.c. If eight feedings are given to twenty-four hours, and each feeding consists of 280 c.c. of milk, 1 egg, and 1 tablespoonful of sugar of milk, the patient will receive approximately 2280 calories, which is ample for an average individual, and if the patient is at rest in bed, it is sufficient to allow a gain in weight. Einhorn has perfected a special syringe, with which it is possible to administer the food without disconnecting the tube. Morgan has suggested a method like that of Murphy for giving salt solution per rectum, permitting the fluid to flow from an irrigating jar, and so arranging the pet-cock that the food is taken slowly, the 300 c.c. of nourishment taking about twenty-five minutes. The food should be administered at body temperature, and the heating should be done slowly, for if it becomes too hot it is liable to become thick and lumpy. After heating it is well to strain the food to be certain to have it free from small particles. If the food is used too warm or too cold it is apt to cause uncomfortable symptoms, sometimes 196 DIETETICS FOR NURSES. causing the patient considerable shock; a too rapid ad- ministration causes flatulence. After each feeding the syringeful of water, at 98° F., should be injected, then the pet-cock closed, and the syringe filled with air, which should be injected after the pet-cock has been opened; the pet-cock should then be closed and the syringe dis- connected. This procedure is very important, and serves to keep the tube clean and empty. If this is not done, small masses of food are apt to be drawn into the lower part of the tube, and this may necessitate its removal. This method of feeding should not be used outside of the hospital, unless it is done by a nurse who has been spe- cially trained for the purpose. In unskilled hands mis- takes are very liable to be made, which cause the patient great discomfort. Saline Irrigations and Infusions.-1. Saline Rec- tal Irrigations.-Rectal saline injections are especially useful in all conditions associated with hemorrhage; also in the various infectious diseases, as well as in intoxica- tions and in those conditions in which it is necessary to allay thirst. The fluid used should be a normal salt solution, and should be given high with the rectal tube; if it is neces- sary to prepare such a solution quickly, a teaspoonful of salt may be added to a pint of water and rapidly injected by means of an ordinary fountain syringe. The fluid should be about the temperature of the body, and should be administered slowly, while the patient is in a reclining position. As much as | to 1 quart of the fluid can be utilized at one time. The Murphy Method for Administering Solutions by Rectum.-A very useful method of administering salt solutions and other fluids is by continuous proctoclysis RECTAL FEEDING. 197 by the drop method, as suggested by Murphy. This may be used whenever it seems advisable to increase the amount of fluid in the system. It is of particular ser- vice when there has been a loss of blood, and also useful to fill up the system so that further lymphatic absorption is impossible, as after operations about the thyroid. It may also be used when fluids cannot be taken by the stomach. Normal salt solution may be used or the solu- tion advised by Murphy, a dram each of sodium chlorid and calcium chlorid to the pint of water. In cases of great weakness, whisky or an infusion of coffee may be added to the salt solution. The method of administering the fluid is important. A fountain syringe, or a salt solution flask, with a rubber tube attachment, terminating in a vaginal hard-rubber tip, or a catheter, may be used. After the insertion of the tip or catheter into the rectum, the flask is filled with salt solution and suspended from 4 to 10 inches above the level of the rectum of the patient. The solution is kept in a temperature of ioo° F. by surrounding the flask with hot-water bags. An improvement on this is to use one of the simple devices which are on the market for regulating the drop. ' This may be done by using a funnel, and so regulating the pet-cock on the flask that the fluid escapes a drop at a time. The devices just mentioned are more satisfactory and require less atten- tion. Care and judgment should be used not to overload the patient with water and so overburden the heart. Plain Water Injections.-In place of using normal salt solution, ordinary water may be used, as suggested by Lawson, 1908, and more recently by Trout. The ad- vantages of the plain water are that it is absorbed in larger quantities and more rapidly. Patients given salt 198 DIETETICS FOR NURSES. solution by rectum require nearly twice as much water by mouth to relieve thirst as those given plain water. The patient does not complain of tasting salt, as is often the case when salt solutions are used. In peritoneal cases in which there is drainage, larger quantities of salt solution or plain water may be used than under other circumstances. Other Solutions.-Foods of various kinds, as men- tioned above, may be administered by this method, and glucose solutions, 30 grams (1 ounce) to the liter of water, or normal salt solution may be used to advantage, especially in cases of threatened or developed acidosis, as in diabetes or following anesthesia. 2. Saline Infusions.-Saline infusions are given subcu- taneously, and are especially useful in cases in which rectal saline irrigations cannot be utilized, as in certain intestinal diseases, or when an immediate effect is re- quired, as in sudden collapse from hemorrhage or from shock. They are also useful in cases when large quanti- ties of fluids have been lost by the body, as in the diar- rheas of dysentery and of cholera; in various infectious conditions and intoxications, as in pneumonia, erysipelas, and typhoid fever; and in the uremia of chronic Bright's disease. The most convenient location for administering the infusion is between the chest-wall and the mammary gland, or deeply into some muscle, as in the lumbar region, abdominal wall, or buttock. The injection should be given under the most aseptic precautions. No appara- tus is required beyond a fountain syringe, to which an aspirating needle is attached. The infusion should be warm and should be allowed to run in slowly; frequently as much as 1 to 2 quarts can be injected into one place. The mixture used is a normal 0.6 per cent, salt solution. RECTAL FEEDING. 199 In certain cases Cushing1 prefers the following solu- tions : Sodium chlorid 0.900 Calcium chlorid 0.026 Potassium chlorid 0.010 Distilled water 99.064 100.000 Combs has reported a fatal case of sodium chlorid poisoning. By mistake I litre of saturated salt solution was ingested hypodermically. When seen four hours later she was comatose. After about six hours of coma, a period of excitation followed, she was maniacal, and talked incoherently. This condition persisted for twenty- four hours, when she died. 124.4 (1928 gr.) of sodium chlorid had been used.1 Soda and Glucose.-In cases of acidosis or where it is feared, 4 or 5 per cent, sodium bicarbonate and commercial glucose may be administered by the Murphy drip. Remember, too much soda can be given. 1 Cohen's Physiologic Therapeutics, vol. lx., p. 289. CHAPTER IX. GENERAL RULES FOR FEEDING THE SICK. The nurse should understand the importance of the proper feeding of the patient. Definite directions as to how much food, its form, its preparation, and how often it is to be given should be written out by the physician. In all acute serious conditions, as in pneumonia or in typhoid fever, a record of these details should be kept, together with the record of the quantity of fluid taken, the medicine given, etc. There is usually a tendency to err in either extreme- that of giving either too much or too little food. Care should be taken that the patient's wishes are, wherever practicable, carried into effect. The nurse should care- fully observe the patient's likes and dislikes, and also note his idiosyncrasies. A tactful, observing nurse is of inestimable value, but a careless or stupid one is an ever- present source of danger. The training of nurses in regard to feeding is often faulty. Every nurse should be instructed in the subject of practical dietetics, and should know how much food is required by the different types of patients. The food should be given at regular intervals. In unconscious or semi-conscious patients this is of great importance; but it is just as important in the conscious, as the appetite usually comes on at certain times, and if the meal is not forthcoming may disappear. The appetite of the conscious patient and of the con- 200 GENERAL RULES FOR FEEDING THE SICK. 201 valescent should be fostered, and nothing done that may in any way disturb it. Patients vary much in this par- ticular, but, as a rule, individuals who are not overfas- tidious when they are well become so when weakened by disease. The sick-room should be orderly, and no dishes, uten- sils, or food be allowed to stand about the room either before or after using. All food and drink should be offered from scrupulously clean glasses or dishes. These should be as dainty as possible, and the food must be made attractive in appearance; when the dish permits, it may be garnished with a sprig of green. The napkins and linen should be spotless. The exterior surface of glasses and cups should be wiped dry before they are offered to the patient. Food that is stale or that has acquired an un- pleasant taste from standing in a refrigerator together with other things should not be given. A strong egg in an egg-nog may be the means of turning a patient forever against this form of nourishment. The food should be tasted by the nurse, but never, when possi- ble, in the patient's presence or with the same spoon. If there is anything wrong with a dish, this should be discovered and remedied before it is brought to the patient. A nurse should always remember the eternal fitness of things. Utensils and dishes should be used only for the purpose for which they are intended and not as makeshifts for other articles. After caring for the patient or removing evacuations sufficient time should be allowed to elapse before feeding is begun. The patient should be made to feel that the utmost cleanliness and care have been observed. The hands and face of the patient 202 DIETETICS FOR NURSES. should be wiped with a moist cloth and then dried before food is given, and the lips cleansed after the meal is completed. The position of the patient should be as comfortable a one as possible, and one in which he will not tire be- fore the meal is ended. If the patient is weak, the food should be given in such form that he may take enough of it without inducing fatigue; otherwise he may become tired of masticating and swallowing and take an insuffi- cient amount. Patients who can sit up in bed should be provided with a bed-tray on which to place the food. The legs of the tray should be placed high enough for the patient to eat comfortably from it. If the patient is helpless, care should be exercised in giving food, so that it will not be drawn into the lungs during inspiration or coughing. This may be avoided by giving the food slowly and by seeing that each mouthful is swallowed before another is given. These patients may be fed in various ways. The food may be given from a spoon, or, what is usually pre- ferred, from a drinking-cup with a spout, or by using a tube and allowing the patient to take the food from a glass. When the patient is taking bread and similar solids great care should be exercised not to allow the crumbs to fall into the bed. In most severe illnesses it is necessary to awaken the patient during the night to administer food. This is a point that requires special judgment. Often the patient is more in need of sleep than of food. If the patient does not drop off to sleep very soon after taking food, it may be better to wait until he awakens before giving it. As a rule, however, in severe illness the sleep is disturbed for but a few minutes by taking food. A GENERAL RULES FOR FEEDING THE SICK. 203 cupful of warm milk or similar food may often induce sleep. The patient's mouth should always be kept clean. If dry and parched, it should be rinsed before and after taking food. Alkaline mouth-washes may be used; boric acid and water also make an efficient wash. If the mouth is dry, it should be moistened from time to time, and for this purpose a little glycerin water and lemon juice will be found useful. If the patient is helpless the mouth may be swabbed out with cotton fastened to the end of a stout probe or wound about the finger. This should be moistened with some antiseptic solution. In all cases where the illness is likely to be protracted, arrangements should be made to care for and prepare the food with as little discomfort to the household as possi- ble. For this purpose a diet kitchen may be improvised, preferably in a room adjoining the patient's. If the patient's means allow, a small sick-room refrigerator should be provided, and a tin receptacle for storing foods that do not need to be kept on ice. A gas or alcohol lamp will serve for heating food. A thermometer, a graduate, a funnel, and filter papers are needed, and a meat-mincing machine will be found a useful addition. Saucepans, a dishpan, and a supply of tea towels should also be provided. Boric acid or borax and sodium bicar- bonate will help to keep things fresh and clean. In cases of infectious and communicable diseases a covered boiler for disinfecting all dishes and utensils should be added. The dishes should be boiled in water to which 2 or 3 per cent, of sodium bicarbonate has been added, and the boiling should be allowed to continue for fully twenty minutes after the water has begun to boil. If this duty is delegated to someone else and the instruc- 204 DIETETICS FOR NURSES. tions are likely to be carelessly followed out, it is best to direct that the dishes be boiled for an hour. Feeding Unconscious and Refractory Patients. -Unconscious patients may often easily be fed by means of a teaspoon. Each spoonful should be swallowed before a second is given. In the case of comatose children, the nourishment may be poured into the nostril instead of into the mouth. The fluid thus given is swal- lowed, and any excess returned by the other nostril. If any difficulty is experienced in swallowing, it is best to resort either to the stomach or the nasal tube. This is usually done by the physician himself. With a little practice most patients can be fed with the tube more easily than in any other way. A mouth-gag should be introduced, or a roller bandage may be placed between the teeth and held in place by an assistant. In infants who have no teeth this precaution is unnecessary, as the finger answers the purpose perfectly. The tube, pre- viously moistened, is passed into the pharynx and rap- idly into the stomach. If the tube is not passed rapidly through the pharynx, contraction may follow and the tube be prevented from entering the esophagus. In order to pass the tube into the esophagus, it is neces- sary to hold it sufficiently well back from the end. If nasal feeding is to be used, a nasal tube, or in case of infants a catheter, is well oiled and gently passed through the nose into the esophagus and then into the stomach. Care should be taken not to pass the tube into the larynx. This accident can always be avoided by waiting a moment before pouring in the food. Either stomach or nasal tube should be provided with a funnel, and as soon as the tube has been satisfactorily introduced, the nourishment-milk, milk and egg, or GENERAL RULES FOR FEEDING THE SICK. 205 whatever liquid food is desired-may be poured slowly into it. In order to prevent air from entering in advance of the food, a small quantity of the food may be poured down the side of the funnel until the tube is full. In many cases it may be desirable to wash out the stomach before introducing the food. The tube should be with- drawn rapidly, so as not to excite vomiting. Food so introduced may be retained when it would otherwise be vomited. This is true both of infants and adults. Forced Feeding.-In case of refractory patients- the insane, the hysteric, and others who refuse to eat- forced feeding becomes necessary. In this case enough attendants should be present to control the patient. He should be held firmly and the nasal or stomach tube may be introduced. In order to prevent regurgitation of the food, which some patients manage to do quite skilfully while it is being introduced, the ribs may be tickled. This prevents fixation of the diaphragm, without which the food can not be ejected. This should be done only when occasion demands. FEEDING IN FEVER. In fever the changes taking place in the body are increased, while the amount of food assimilated is de- creased. For this reason, even if the patient is well fed, a certain amount of the body substance is burnt up. If the patient is poorly fed or the fever protracted the emaciation may be extreme. The appetite is diminished or lost entirely, and it may require great tact on the part of the nurse to see that the patient takes sufficient food. The thirst is increased. Foods appropriate for healthy individuals are not, as 206 DIETETICS FOR NURSES. a rule, suited for fever patients, and solid foods usually cause vomiting or severe indigestion. In order properly to nourish a fever patient, it is necessary that the food be easy to take, easy to digest, and easy to assimilate. Any food that does not possess these three qualities is not suitable for a fever patient. When the disease runs its course rapidly, the diet is of no great importance, for even if the patient take but little food, the period of com- parative fasting is a brief one and any loss is easily made up while recovery is in progress. In protracted dis- eases, on the other hand, such as typhoid fever, and in chronic fevers, the diet is of primary importance. In chronic diseases and in those fevers where remissions occur, the periods when digestion is comparatively good should be taken advantage of and the patient nourished and strengthened as much as possible. In fevers the mouth requires especial care; the bowels likewise should be regulated and constipation avoided. Suitable beverages should be given to allay thirst, and if the patient is not getting sufficient liquid with his food he should be offered water or some other drink every three or four hours. This should be done whether or not the patient is conscious, for a patient seemingly con- scious is often in an apathetic condition. The water is required not only to quench thirst, but to aid in the elimination of waste products, which, owing to the in- creased metabolism, are augmented. The most suitable of all drinks is plain water. When this does not agree, or to meet special indications, mineral waters are often of great use. The natural waters, since they do not con- tain such large amounts of carbon dioxid, are best. If the artificial waters are used-and this is generally the case-they should be allowed partially to effervesce GENERAL RULES FOR FEEDING THE SICK. 207 before being given to the patient, lest the gas in the stomach cause unpleasant symptoms. The " Imperial Drink " (see Recipes) is very useful and is generally taken with a relish. To this may be added the white of an egg, beaten up and strained, if the patient is not taking much food. Both lemonade and orangeade are useful, and the former is particularly valuable. Since the hydrochloric acid of the stomach is deficient during fevers, water acidulated with hydrochloric or phosphoric acid is of service, as it increases the powers of digestion. Barley water, oatmeal water, toast water, and albumin water are all of service, containing, as they do, nourish- ment with drink. Albumin water is made by beating up the white of a fresh egg, straining it through a cloth, and then adding six or eight ounces of water. This may be flavored with lemon, orange, sherry, or cognac. Wine whey is also of value, and under certain circum- stances, as in affections of the bladder, flaxseed tea or gum water may be given. Rarely, beer or some other beverage is permissible. To those accustomed to taking large quantities of beer daily this may be the only means of getting the patient to take nourishment. The food for fever cases should always be liquid. Milk, as it contains various food elements in a suitable combination, is the best of this class of foods, and if properly administered agrees with most patients and is easily digested. It should, as a rule, be diluted, and a small quantity of lime water or sodium bicarbonate should be added to it. Lime water may be added in amounts varying from 5 to 50 per cent., according to circumstances. Vichy or Seltzer water, or even ordinary water, may be used, and may be flavored if the patient prefers. Barley water or oatmeal water may be mixed 208 DIETETICS FOR NURSES. with it, or, what is sometimes of great service, equal parts of a cereal water and milk may be boiled together. If the mixtures mentioned do not agree the milk should be peptonized. Milk should not, however, be pepton- ized if the patient can take and digest it without pep- tonization. Buttermilk, kumiss, or whey may also be used. Buttermilk, however, contains less nourishment than milk; kumiss may not be relished at first, but many patients soon learn to like it. Lastly, infants' and in- valids' food may be given. Malted milk may be enjoyed by the patient, and is useful in those cases in which there is diarrhea. Eggs may be given raw or in the form of albumin water, and an excellent mode of administration, especially if the patient requires a stimulant at the same time, is to give the time-honored Stokes' brandy-and-egg mixture. Given in this form the egg generally agrees. It may be well to make up the mixture with one-quarter or one- half the amount of brandy. Meat juices and broths, for which recipes will be given further on, may be used. The meat extracts are best given well diluted. The variety of broth should be changed each day, using beef, veal, mutton, and chicken in turn, to avoid monotony in the diet. The various predigested beef preparations and beef juices sold in the shops may be used at times, and are often of great value, especially when the patient can not retain other forms of food. Strained vegetable broths are useful occasionally in long-continued fevers, and gelatin prep- arations, such as calves'-foot jelly, wine jelly, or fruit jelly made with gelatin, may also be employed. Fruit juices, especially lemon, orange, and raspberry juices, are generally relished. These should be diluted, and are GENERAL RULES FOR FEEDING THE SICK. 209 best given cold or with cracked ice. Solutions of grape sugar alone or drink sweetened with grape sugar are to be recommended. Granulated extract of malt dissolved in water or milk is relished by some patients. The question as to the value of alcohol in fevers is one that has been widely discussed. While alcohol has doubtless been greatly abused, it is of value both as a food and as a stimulant. The quantity to be given and the question whether it is to be given or not are to be decided only by the physician. Both questions de- pend upon circumstances, and the age, condition, habits, and tolerance of the patient all play an important part in deciding this question. It is usually prescribed in small doses at regular intervals, and should, if the stronger forms are used, be sufficiently diluted with water. CHAPTER X. FEEDING IN THE INFECTIOUS DISEASES. The management of the diet in typhoid fever is one of the most important things for a nurse to know. The diet to be followed is ordered by the physician, but it will depend upon the nurse to see that his orders in this respect are carried out in an exact and intelligent man- ner. Whether the patient will get sufficient food or not frequently depends on the tact and attention of the nurse. In this disease there is a diminution of the digestive and absorptive powers. The digestive juices are less active and the functions of the liver more or less dis- turbed. In addition there are ulcerations in the intestine, which may go on to perforation. During fever the metabolism is increased, and unless sufficient food is taken and assimilated the body protein will be used up and emaciation result. This always occurs to some extent in all cases, no matter what the food, and severe emaciation may also occur in well-fed cases from other causes. It should be borne in mind that a mild case of typhoid fever should be dieted with the same care as a severe one. Food and drink should be given at regular intervals, both by night and by day; the appetite of the patient should not be consulted, for these patients are often apathetic or have no desire for food. The food should TYPHOID FEVER. 210 FEEDING IN THE INFECTIOUS DISEASES. 211 be given at intervals of from two to four hours, accord- ing to the condition of the patient and the quantity taken at a time. Those who are strong and in comparatively good condition may take their nourishment at four-hour intervals during the night, even if it is given at more frequent intervals during the day. The question of drink is also of great importance in these cases, for in some patients severe thirst is a very disagreeable symptom to combat. Pure water, given with or without ice, is to be depended upon, but if there are no contra-indications this may be varied in many ways. The natural spring waters, or if these can not be obtained the artificial ones, are often useful. The artificial waters contain large quantities of carbon dioxid, and to avoid trouble they should always be allowed partially to effervesce before they are given to the patient. If there is no marked bowel disturbance, fruit juice maybe added to the water. Lemonade, orangeade, raspberry juice, and raspberry vinegar and water are often welcome changes. Weak tea, especially if a little red wine is added to it, is an admirable thirst quencher. Cold weak coffee is relished by some. Red wine and water, white wines, or even sherry or brandy and water may be given to some patients, especially if plain water causes unpleasant symptoms. When there is irritability of the intestine or severe diarrhea, red wine and weak tea are to be preferred. Albumin water, since it combines food and drink, is most useful. It may be flavored with lemon or orange juice, or may be shaken up with a little sherry or brandy and ice. (The egg, which should always be perfectly fresh, should be beaten and then strained through a cloth.) The various mucilaginous drinks may be used, but are not generally relished. Gum-arabic 212 DIETETICS FOR NURSES. water, arrowroot water, bread water, barley water, oat- meal water, and similar beverages have their place in the physician's list of possibilities. Milk.-The food par excellence in this disease is milk. There is no one food that meets so many indications. It possesses great nutritive value, is easily procured, as a rule, and is generally easily administered. It must be borne in mind, however, that there are some patients with whom milk disagrees, and many who do not like it. Milk, however, disagrees less commonly than is gener- ally imagined. The amount to be given daily varies between one and three quarts, according to the patient. There are not many patients who can take three quarts of plain milk, and it is generally a good plan to vary its form of administration, and occasionally to substitute for it other articles, which will be mentioned further on, so that the patient may continue to take milk during the entire course of the disease. If milk is given plain, it is only a question of time when it will disagree with any patient. Children are more apt to take it over long periods of time than are adults. At the Garrett Hos- pital for Children in Baltimore the authors seldom use anything besides milk for typhoid cases, and do not find it necessary to make changes in it. For older children or adults it should always be modified. When milk forms the diet, the mouth requires particular care, as the little milk that remains in the mouth often turns the patient against the next feeding. There are many ways of modifying milk and render- ing it more agreeable and more digestible to the patient. The simplest method is to add from one to three ounces of lime water to each glass of milk, or plain water or a mineral water may be used instead. If milk is well borne FEEDING IN THE INFECTIOUS DISEASES. 213 and it is desired to increase the amount of nutriment, cream may be added to it. If this causes unpleasant symptoms it should be discontinued at once. Butter- milk may be given occasionally, but is far inferior in nutritive value to plain milk. Kumiss or kefir may be used, and while they may not be relished at first, most patients learn to enjoy them. A pinch of salt may render milk more palatable to some persons, and the addition of a spoonful of brandy may be relished by others. The milk may be given cold, be flavored with fruit juices, vanilla, or nutmeg, or it may be given in the form of ice cream. When milk is not well borne, it is a good plan to prepare barley water and add to it an equal quantity of milk, boiling them together for a few minutes. Plain boiled milk may also be used with benefit. Among the disagreeable symptoms to which milk gives rise may be mentioned a bad taste in the mouth, which, however, is apt to be present in any case; a sense of fulness or pressure in the abdomen ; eructation ; or even pyrosis. When the milk is not well digested it may cause diarrhea, with colicky pains, and the undigested curds will be found in the stools. To obviate these symptoms the measures previously suggested may be tried (see also Milk Cures). Malted milk may be used, or the milk may be mixed with some of the invalid foods, or it may be partially or completely peptonized. For the last purpose the peptogenic milk powder will be found useful. When milk is found to disagree, other forms of nutri- ment must be given. If care is taken to supplement its use by other foods from the beginning, the milk will be less apt to cause disturbance. The carbohydrates are valuable foods in typhoid and may be used in many different forms. Of these, DIETETICS FOR NURSES. 214 the various gruels are the most easily digested, and may be given plain or mixed with milk or bouillon. Oatmeal, thoroughly cooked (three hours' boiling at least) and strained, is best, but may not agree with the patient. Barley water (Robinson's barley flour is an excellent preparation for making barley water), arrowroot, sago, tapioca, and the prepared foods may all be used. In Germany aleuronaut flour is added to bouillon or soups. Of the proteins and allied substances there are a number that may be used. Meat is to be forbidden so long as fever occurs. Fat must be skimmed from soups, broths, and bouillon, as it is apt to disturb the patient's digestion. Beef juice made according to any of the recipes given in the Appendix may be used, or beef juice expressed from very slightly broiled beef or skimmed dish gravy may be used. This may be served in a green glass if the color of the juice is objectionable. Bottle bouillon may be employed, as may also the vari- ous liquid beef preparations and meat juices now on the market. Mosquera Meat Jelly and Valentine's Beef Juice are useful but expensive. Beef extracts are more stimulating than nutritious. Senator recommends gelatinous substances, such as gelatin, calves'-foot jelly, bottle bouillon, and the like. Oysters may be served with gelatin. The gelatin jellies may be flavored with fruit juices or with wine. Eggs should be used sparingly. Egg water, how- ever, when properly prepared, rarely causes distress. Raw eggs may occasionally be given, or the yolk of an egg in bouillon or broth. Eggs and milk together may cause indigestion; but if the patient is in need of a stimulant as well as a food, Stokes' brandy-and-egg mixture may be used, and in moderate quantities rarely disagrees. FEEDING IN THE INFECTIOUS DISEASES. 215 Somatose, eucasin, nutrose, and similar preparations may be mixed with bouillon or other foods. Alcohol holds an important place as a food as well as a stimulant in long-continued fevers. The tendency to- day is to prescribe it in smaller quantities than formerly, and many have abandoned its use altogether. It is, nevertheless, a valuable ally in fighting typhoid, and should not be discarded. It is not given to children as a routine treatment, but even in young patients it is often of the greatest service. When given to adults, it is well to begin with very small doses and to increase these as the patient grows weaker or as the fever continues to progress. Too much should not, however, be given; and if the dosage has been too large at first, it can not be increased as needed later on. In habitues, alcohol will be needed from the outset. The form of alcohol to be used is largely dependent on the patient's taste. As a rule, good old whisky, properly diluted, is best. Old brandy is good, but much of the brandy sold is of very inferior quality. The red wines are useful, especially when there is diarrhea, and the old white wines are excellent if the patient cares for them. The brandy-and-egg mixture previously mentioned is very useful. High Caloric Diets.-Of recent years there has been a tendency to increase the amount of food given typhoid fever patients, and for this purpose a considerable choice of foods is desirable. The following are the most suitable: Milk. Cream. Buttermilk. Whey. Junket. Matzoon. Kumiss. Cocoa. Chocolate. Ice cream. Malted milk. 216 DIETETICS FOR NURSES. Soups.-Beef, veal, chicken, tomato, potato, etc. These may be thickened with rice, barley, arrowroot, wheat flour, or with egg or milk. Well-boiled rice, sago, or barley may also be used. Raw eggs. White of egg. Yoik of egg. Custards. Egg and milk. Stokes' brandy and egg mixture. Egg-nog- Milk toast. Crackers and milk. Well-cooked cereals, such as rice, barley, cream of wheat, sago, arrowroot, cornmeal. Soft puddings. Blanc mange. Cornstarch pudding and similar preparations. Thoroughly cooked macaroni and spaghetti. Apple-sauce, lemonade, orangeade. Gelatin jellies. Scraped meat, raw or boiled, given with care and only in small amounts. Oatmeal is ordinarily not suited as a food for typhoid fever patients, but sometimes is used. It should be cooked five hours and strained. Pea-soup and bean-soup have been suggested, but or- dinarily are objectionable on two grounds-the purin nitrogen contained and their great tendency to cause flatulence in some patients. Baked or mashed potatoes may be used sparingly. If the patient is sufficiently well, a considerable amount of food may be given; but it should be borne in mind that any food that disagrees should be discontinued, lest the disturbance so caused should interfere seriously with the future feeding of the patient.

Saunders' Nursing Service Books August, 1923 WILLIAMS' ANATOMY AND PHYSIOLOGY Published August, 1923 To help the teacher help the student-that is the keynote of a new Text-book of Anatomy and Physiology, by Jesse Feiring Williams, M. D., who brings to his task his experi- ence at Teachers College, Columbia University, New York. He has lightened the teaching difficulties generally asso- ciated with the subjects of anatomy and physiology-and he has lightened greatly, too, the difficulties of the nurse in mastering these subjects. The approach is the biologic one, beginning with the cell and following through the dif- ferent systems of the body. Embryology is given a dis- tinct place, and bones, muscles, nervous system, and viscera are given meaning in the light of origin and develop- ment. Many suggestions are embodied for the practical application of the theory. At the end of each section is a series of exercises, a group of spirited questions, and a list of selected references. The recommendations of the ''Standard Curriculum for Schools of Nursing" have been followed. There are 379 illustrations. By Jesse Feiring Williams, M. D. Cloth, $3.00 net. % % WILLIAMS' PERSONAL HYGIENE APPLIED Published July, 1922 This book is far more than a recital of information on health. It establishes a new interpretation of health in terms of life. It is personal hygiene applied. The first five chapters consider the various aspects of this problem -the meaning of health in terms of life. The remaining chapters consider in a systematic way hygiene from its scientific side. The book aims to be scientific and accurate according to the latest information available. It has tried to avoid propaganda, to convert or to get people to follow a scheme. It has aimed to present facts in human experi- ence, to establish science and intelligence as guides. By Jesse Feiring Williams, M. D. Cloth, $2.50 net.

Saunders Nursing Service Books PORTER'S PSYCHOLOGY FOR NURSES Published September, 1921 Years of experience in schools and colleges, in a neuro- logic hospital and a large city general hospital convinced Miss Porter that it is of little avail to cure the body and let remain with the patient a "sick attitude." To teach nurses how to prevent this attitude, or avert it, is the aim of this book. Every well-trained nurse should consider it an essential to her professional success to leave her patient imbued with the will to health and better equipped to attain it because the sick attitude is not present. The simple principles of psychology as here presented will enable the nurse to treat the sick mind as well as the sick body. By Mary F. Porter.

Care of the Mouth.-This is of primary importance. If begun early and persisted in, many undesirable mouth conditions can be avoided. If the mouth is in good condition the patient can, as a rule, take his food easily; 224 DIETETICS FOR NURSES. if it is not, the greatest difficulty may be experienced. After each feeding the mouth should be cleansed care- fully, a proceeding that should never be neglected. If the patient is strong enough he may rinse the mouth with a mild antiseptic solution. Boric acid solutions to which a little glycerin and lemon juice have been added, or one of the prepared mouth washes diluted with water, may be used; diluted oxygen peroxid is also serviceable. If the patient is too weak to do this, the nurse should swab the mouth. Diet in Digestive Disturbances.-In cases where the food is rejected or badly borne it is necessary to give the stomach absolute rest for several hours or more. Then very small quantities of egg water, barley water and lemon juice, or similar preparations may be given. Panopeptone and the liquid beef preparations are use- ful in this condition, and may be served with cracked ice or diluted with water. Weak tea or red wine and water in small doses are useful, especially if there is diarrhea. For the diarrhea an ice-bag to the abdomen has been highly recommended, but is seldom well borne. Instead, cloths moistened with cold water may be used. For the painful and troublesome accumulation of gas in the intestine, either the ice-bag or the cold applications may prove beneficial. The authors have obtained excel- lent results from the use of turpentine stupes. When the meteorism is due to the imperfect digestion of starch, the carbohydrates should be reduced or withdrawn; when it is due to milk, the form in which this is given should be changed or it should be withdrawn altogether for a time. Hemorrhage.-When hemorrhage from the bowel occurs the intestinal tract should be given absolute rest FEEDING IN THE INFECTIOUS DISEASES. 225 for a number of hours. An ice-bag, cold applications, or a cold-water coil should be placed upon the abdomen. To relieve the thirst the patient may be allowed to suck small bits of ice, or ice-cold water or cold tea may be given in spoonful doses. After some hours the patient may be given a teaspoonful of cold milk, and this may be repeated every two or three hours. Beyond this, if the bleeding is severe, the intestinal tract should be given complete rest for twenty-four hours or longer. In addi- tion the physician may order opium or morphin. The return to the regular fever diet should be made gradually and with caution. Perforation.-When perforation of the bowel occurs all food should be discontinued. The patients are usually operated upon as soon as possible or the patient is given anodynes. Following operation, the diet will be that of any bowel perforation that has been operated upon. If the patient rallies without surgical intervention, or when this has been found impracticable, food may be given after an interval of twenty-four hours, but only in very small quantities at sufficiently wide intervals. It is best to begin with teaspoonful doses every three hours, and if the food is retained this may gradually be increased. Usually food is rejected, and when this is the case the stomach should be given complete rest, for feeding only tends to aggravate the condition. Convalescence.-The diet during the first weeks of convalescence requires as much care and attention as it received throughout the febrile period; in fact, since these patients often develop a ravenous appetite, born of several weeks' milk diet and fever, even greater care is necessary. The patient's wishes should in nowise govern his diet, and relatives and friends should be cautioned 226 DIETETICS FOR NURSES. against giving the patient anything not ordered by the physician. Many a relapse and death has been caused by the misguided kindness of friends and relatives in this respect. When there has been severe bowel disturbance, the patient is to be kept on a liquid diet until the ninth or tenth day of the afebrile period. After mild cases, where there has been but little bowel disturbance, changes may be made in the diet after the fifth or sixth afebrile day. In these mild cases the greatest caution is required, as they are often quite as apt to do badly as are the severe ones, and the attendants are much more likely to be careless in carrying out instructions. The first addition to the dietary should be made by giving a piece of zwieback over which hot milk or cream has been poured. If desired, milk toast, milk and crack- ers, or junket may be substituted for this. If this is well borne, other articles, such as soft-boiled eggs, or the soft part of oysters, if they are in season and can be obtained fresh, may be added from day to day. Thick- ened meat broths containing well-boiled rice or vermi- celli may be given. Finely scraped raw beef, reduced to a pulp in the manner suggested for tuberculosis patients, also lends variety. Tender meats, vegetables, and breadstuff's in increasing quantities may be allowed. Roast chicken, squab, or partridge, boiled (white) fish, such as trout; of the vege- tables, spinach, cauliflower tops, asparagus tips, purees of peas, carrots, or tender string-beans or artichokes, well-cooked rice, and baked potato mashed and served with cream or dish gravy; toast, zwieback, crackers, and the crust of bread may all be permitted. If the condi- tion of the bowel permits, fruit juices may be allowed, as well as a baked apple, apple sauce, or junket flavored FEEDING IN THE INFECTIOUS DISEASES. 227 with fruit. Other sick-room delicacies may be ordered at the discretion of the physician. Chops, tender steak, and roast beef may generally be given in the third afebrile week (very finely divided meat may be allowed much earlier), and the diet gradually changed until the ordinary diet is resumed. For some time after an attack of typhoid fever the patient should be instructed to exer- cise care in the selection of his diet, and especially to avoid all food, such as green fruit, green corn, crabs, and the like, that is likely to cause diarrhea. The following menu for the first week of convalescence may serve as a guide and may be altered to suit the in- dividual case. It may be begun about the fifth or sixth afebrile day in mild cases, and about the ninth or tenth in severe cases. Milk should form the bulk of the diet at this period. First Day.-Milk toast, or zwieback covered with hot milk or cream, or crackers and milk; beef juice. Second Day.-Chicken broth thickened with rice or vermicelli (the rice should be boiled thoroughly); soft parts of several oysters, or a very lightly boiled egg- Third Day.-Junket; a meat broth thickened with well-cooked barley (boiled at least three hours), with barley flour, or with stale bread crumbs; wine jelly; scraped raw beef. Fourth Day.-Lightly boiled or poached egg; arrow- root, barley gruel, or milk toast; chicken jelly. Fifth Day.-Junket; a little well-boiled rice with a small amount of finely divided roast chicken, squab, or partridge, preferably the white meat; apple sauce if bowels permit. Sixth Day.-Scraped beef; poached egg; calves'-foot jelly; baked custard; piece of toast or zwieback. 228 DIETETICS FOR NURSES. Seventh Day.-A small piece of finely divided broiled chop or steak ; baked potato ; baked apple; well-boiled rice and cream for breakfast; junket for supper. Atypical and Complicated Typhoid.-In these forms the physician often departs from the usual course of diet and orders a diet to meet the special indications. TYPHUS FEVER. The diet is that of all fevers and requires no especial precautions. Milk is the main stay, and a quart of milk and a pint of broth may be regarded as a fair daily allow- ance. Eggs are better borne than in typhoid and may be allowed. Rolls, zwieback, and chopped meat are allowed by some physicians even while there is fever. Black coffee is useful if there is stupor. Water should be given freely. SMALL-POX. The usual fever diet is used. Owing to the great drains on the patient's system when the stage of sup- puration is going on, it is desirable that the patient be fed up as much as possible during the stage of remission of the fever. If there is much pain on swallowing, and there often is, the food may be given cold. SCARLET FEVER. One of the chief dangers of scarlet fever is inflamma- tion of the kidneys, and the diet should therefore be bland and unirritating. A milk diet, continued for a month, is perhaps the safest but difficult to carry out, and we have recently been more liberal, allowing farinaceous foods, and, in fact, almost any purin free food may be allowed, FEEDING IN THE INFECTIOUS DISEASES. 229 taking care not to give those things which are known to be irritating to the kidneys. (See Diet in Nephritis and Purin Metabolism.) The various modifications of milk may be used. Kumiss and buttermilk are of especial value in some cases, and oyster and clam broth, from which the shellfish have been removed, may be given. For the thirst, which is generally great, plain or car- bonated waters, barley water, orangeade, or lemonade may be given freely. A level teaspoonful of cream of tartar mixed into a glass of lemonade is a diuretic drink if albuminuria is present. If edema is present, the physician generally orders a restriction of the fluid, and salt is generally omitted from the diet. Plain vanilla ice-cream or plain lemon-juice may be given in small quantities. Finely shaved ice, also in very small quanti- ties and flavored with a little lemon or orange-juice, often makes a great addition if angina is marked. Cereal gruels, with or without milk, are very useful, and well- cooked cereals, with the exception of oatmeal, about which there is still some question, milk toast and milk, or crackers and milk, are very useful. Useful puddings made of cereals and milk are also of service. Fruit may be given in moderation, its juice being perhaps the best to use, grape-juice and apples, or, if there is constipation, stewed prunes may also be used to advantage. In all cases the return to a general diet should be made gradu- ally, starting with eggs and dishes made out of eggs, and adding from day to day boiled or baked fish, the soft parts of oysters, the lightest and most easily digested meats, the white meat of chicken and raw or very rare beef, and gradually the general diet. During the height of the dis- ease and throughout convalescence meat extracts should be avoided, as they contain large quantities of extracts which are liable to irritate the kidneys. 230 DIETETICS FOR NURSES. MEASLES. The diet is that of any fever. No especial precautions need be observed. MUMPS. Liquid diet should be given while the fever and swell- ing exist. Acids and astringents should be avoided on account of the intense pain they are liable to cause. The diet requires close attention, especially if the case is severe. Mild cases should be given a light general diet. If the case is severe a liquid diet should be given, and this should consist largely of milk. The great diffi- culty is that the food is liable to be vomited at the close of the paroxysms. This may occur so frequently that the child has difficulty in retaining sufficient food to nourish it. A good plan is to give another meal in place of the one which has been vomited, as soon as the child is able to take it. WHOOPING-COUGH. DIPHTHERIA. Egg-nog and milk punch are sometimes useful, although, as a rule, stimulants are best given alone and not com- bined with the food. If the patient can not swallow, nutrient enemata may- be resorted to; a nasal or a stomach tube may be em- ployed. If the latter mode of feeding is adopted, care should be taken to avoid struggles with patients whose hearts are weak. In all cases, if there is any fever, the food should be liquid and should be given in small quantities at regular intervals. The most useful of the liquid foods are milk, plain, with lime water or a carbonated water, or pepton- ized albumin water; some form of predigested beef, FEEDING IN THE INFECTIOUS DISEASES. 231 liquid beef peptonoids or panopeptone; soups and gruels, and the various prepared foods, of which malted milk, Eskay's or Mellin's foods are examples. Occasionally semi-solids are swallowed with greater ease than liquids; in this case any of the foods just men- tioned may be thickened with well-cooked cereals or gelatin, or custards or junket may be given. Ice cream, if plain, may be allowed in moderate quantities. Intubation.-After intubation has been done there may or may not be some difficulty in swallowing. As a rule, when the child swallows for the first time there may be a slight cough or some hesitation; in the majority of cases, however, this disappears as the appre- hension of the child is allayed. There may be a little difficulty for the first day, but this passes off gradually as the muscles become accustomed to work under the new conditions. If the child is old enough he should be instructed to take the food as rapidly as possible and then to cough afterward, instead of after each act of deglutition, as he is apt to do. In some children there may be a slight regurgitation through the nose. Taken all in all, the difficulty experienced in feeding these cases is small compared to the enormous benefit the child derives from the operation. If there is difficulty in swallowing liquids, solid or semi-solid food may be given instead. The child may be placed with his head lower than his body. In this position swallowing becomes easy. The child may also lie across the nurse's lap, with his head thrown well back and down. Sucking liquid food through a tube is another way of taking food in these cases. It should always be remembered that food may be refused because of nausea, or because the child has no desire to take DIETETICS FOR NURSES. 232 anything, as well as owing to any actual difficulty in swallowing. The diet should be the same as in non-operative cases, and if semi-solids or solids are required, soft-boiled eggs, milk toast, custards, bread and milk, oatmeal porridge, and similar foods may be given. If swallowing becomes impossible, an event that oc- curs very rarely, the child may be fed with the stomach or nasal tube or by means of nutrient enemata. No especial dietetic rules are necessary for feeding tracheotomy cases. Postdiphtheric Paralysis.-In paralysis of the muscles of deglutition which may occur after diphtheria, most of the food may return through the nose ; or if the muscles of the tongue as well as the soft palate are in- volved, deglutition becomes impossible. When this oc- curs, the child must be fed with the stomach or nasal tube or by the rectum. RHEUMATISM. The diet in this disease is still a matter of dispute. During the acute stage it is best to give milk or a milk and farinaceous diet. Buttermilk, gruels, and the like are useful. A gradual return is made to the customary diet. YELLOW FEVER. Food is usually withheld during the first stage of the disease, as it is almost certain to be vomited if given and only aggravates the condition. Stimulants and saline solution and even food may be given by rectal injec- tions. Milk and lime water or albumin water are given during the third day and the diet gradually increased as the physician sees fit. If the patient grows worse every- thing is vomited. FEEDING IN THE INFECTIOUS DISEASES. 233 TETANUS. Liquid nourishment is given, when possible, between the teeth; if the teeth fit too closely together it is some- times customaiy to remove one. A nasal-tube can be used in some cases and a rectal tube in others. When the disease is so severe that the slightest movements about the patient produce convulsions, feeding becomes impossible except while he is under the influence of an anesthetic. Only those who have seen this terrible disease appre- ciate the difficulties in feeding these patients. Liquid nourishment may be given so long as the patient can swallow if he desires food. Even the slightest move- ments near the patient produce spasms, and, as the result is uniformly fatal, it is not necessary to add to the patient's sufferings by trying to feed him. RABIES. TUBERCULOSIS. Diet in tuberculosis is of primary importance. We shall consider only pulmonary tuberculosis, for the same rules apply to all forms. The weight of the patient is a fair guide as to the state of his nutrition. This should be borne in mind, for in recent years overfeeding in tuberculosis has been somewhat over- done. In addition to the food it is essential that the patient should have an abundance of fresh air, carefully regulated hours for rest and exercise, and the whole life must be so ordered as to secure as great freedom from care and worry as is possible. In addition to the full night's rest it is a good plan for the patient to lie down at least half an hour after each meal. The individual requirements of the patients differ 234 DIETETICS FOR NURSES. greatly, and food, rest, and exercise must be suited to the individual. The food is to be chosen from the articles mentioned below, although other things may be given. It should be made as attractive as possible, and Detweiler was fond of saying, " My kitchen is my pharmacy." The food should be ready at the time the meal is served, and the service should be prompt, so that the patient is not tired out waiting between courses, and also that he does not lose his appetite and patience. The plate should not be piled full of food which the patient is expected to eat, but smaller and repeated helpings have been found to be better. Congenial table companions are a great stimulus to eating, and many patients eat fairly well if seated with others who are cheerful and have good appetites. As a rule, the food should be taken in as concentrated a form as possible, as individuals with weak stomachs may have digestive troubles started if the bulk is too great. This is not so important in working people, as their diet is ordinarily rather bulky; in fact, if some people, accustomed to bulky diet, are given the same food value in a more concentrated form, they claim it does not satisfy their hunger. The dinner may be taken in the middle of the day if desired, and the rather lighter meal taken as supper in the evening. Milk.-This is one of the most important articles of diet for the tuberculous patient. Unless some special reason exists, milk should always form a part of the diet. It may be taken with the meals or be given between the intervals of feeding. It is of the utmost importance that the milk be sipped slowly and not swallowed quickly in large quantities. The milk may be taken plain or may be modified in various ways. Lime-water may be FEEDING IN THE INFECTIOUS DISEASES. 235 added, with or without the addition of cream; carbon- ated water may be mixed with it or the milk may be peptonized. Buttermilk or kumiss may be taken if desired. KggS, when they can be taken in sufficient quanti- ties, are also of the greatest value. In certain cases, however, they may not be well borne. If the entire egg can not be taken, the whites alone may be given. Egg albumin often renders most efficient service in helping to nourish these patients. The whites of from six to twenty-four eggs beaten up lightly and strained through a cloth may be taken daily. A very small pinch of salt and a little lemon juice or other flavoring substance may be added. Given in this way a large number of eggs can easily be taken and are almost invariably well borne. If the patient can digest the eggs entire they may be very lightly boiled, or, as a change, they may be made into a light omelet or poached. Meat.-Meat of all kinds, if properly prepared, may be eaten ; but " high " game, highly seasoned dishes, and twice-cooked meats should be avoided. Beef and mutton are the most suitable varieties. Raw meats, especially raw beef, is given in the form of a finely divided pulp. This is prepared by scraping the meat with a knife, which will result in a mass of shredded meat fiber. This is placed in a mortar and pounded and rubbed with a pestle until quite smooth. It is then pressed gently through a sieve to remove any larger particles. This raw meat pulp is very easily digested and highly nutritious. It may be given in various ways, as spread on sandwiches or given in milk or in warm bouillon. It may be mixed with purees of various kinds or with vegetables, or, in case of children, with small 236 DIETETICS FOR NURSES. quantities of preserves. It may be rolled into balls and, so, easily swallowed; or it may be served with an egg, with anchovies, or with pickled herring. Meat juice is also of great value. This may be pre- pared according to any of the recipes given in the Appen- dix, or the juice may be expressed from beef by means of a meat press. Good round-steak should be very slightly broiled, cut into small cubes, and the juice pressed out. With a good press about eight ounces of juice can be extracted from a pound of meat. This should be seasoned, and heated by placing the vessel containing it in warm water. Care should be taken not to heat it too thoroughly, or the albumin will coagulate and the juice be spoiled. Freshly prepared beef juice is always preferable, but when this can not be obtained, liquid beef peptonoids, predigested beef, or Mosquera Beef Meal may be employed. For patients who can not or will not take raw beef, very rare steak, roast beef, or beef soup should be sub- stituted. Fish.-Fresh fish, boiled, broiled, or baked, may be allowed. Both oysters and clams from which the hard portion has been removed may be eaten, preferably raw, but they may also be given stewed, roasted, or broiled. Cereals.-Where these can be digested they are of value. In the early stages of the disease they serve not only as nutriment, but also aid in regulating the bowels, and are usually easily digested. If there is constipation they are of especial value. Oatmeal, wheaten grits, cornmeal mush, and rice and milk are the most suitable forms. FEEDING IN THE INFECTIOUS DISEASES. 237 Vegetables.-Any of the easily digested vegetables may be allowed. They should be steamed or cooked with as little water as possible, to avoid dissolving out the salts, which, together with much nutriment, are thrown away with the water. Wheat.-Wheat or rye bread or a mixture of both may be used. Zwieback is of great value. All hot breads, pastry, and cakes should be avoided. Fruit.-All fresh and, preferably, ripe fruit may be allowed in moderation. It should be taken the first thing in the morning or as a dessert. Oranges and baked apples are well borne and useful, and grapes, peaches, pears, and other fruit in season may be allowed. Fats.-In tuberculosis, when fats and oils can be taken and absorbed, the prognosis is always much better than when these can not be tolerated. While they are of the greatest value in treatment, care should be taken not to disturb the patient's digestion by forcing more fatty foods into the dietary than the stomach will toler- ate. Most patients, however, soon acquire a dislike for fats of all kinds. They are best given in the form of cream and butter; the yolks of eggs, crisp fat bacon, and olive oil are also useful. Cod-liver oil is really as much a food as a medicine. Either the plain oil or an emulsion may be used, and the doses should be small to begin with and gradually be increased. A common mistake is to administer the oil in excessive quantities. Only perfectly sweet fresh oil is to be used, as rancid or stale oil may disturb the digestion. Its use should be discontinued from time to time. Children bear oil better than adults. If there is a tendency to diarrhea, fats and oils must be used with caution. 238 DIETETICS FOR NURSES. Alcohol.-Concerning the use of alcohol in the treat- ment of tuberculosis, it may be said that, except in the last stages of the disease, it is best avoided. Patients who are gaining in weight or who are in good condition are better off without alcohol. Those who are going down hill may often take light wine, beer, or well- diluted spirits with advantage. Of the last, well-matured whisky is the best. Patients with high fever who are in an exhausted con- dition may be given alcohol freely, following the same rules as were laid down in the general consideration of fevers. In these cases alcohol is given as a food, and is, as a rule, well borne. In these advanced cases pure whisky well diluted is perhaps the best form of alcoholic stimulant, but the patient's taste may be consulted in this respect. Other Beverages.-The usual beverages may be given in moderation. In chronic tuberculosis cocoa may be taken night and morning with good effect. Tea or coffee may be allowed in small quantities unless they produce unfavorable symptoms. Milk and milk punch, buttermilk, lemonade, or orangeade may be used, and malt extracts are often of benefit. Number of Meals.-Food may be given from three to six times daily. On rising milk may be taken, or if desired a cup of bouillon instead. If desired a glass of milk may be given early before breakfast, before the patient has got out of bed. Breakfast.-A glass of milk. This may be flavored with tea or coffee and taken from a coffee cup if desired. If the patient wishes it, an orange or a small amount of some other fruit, an ordinary helping of oatmeal, two soft- boiled or poached eggs, two slices of toast or bread, and half ounce of butter. A small piece of bacon may be FEEDING IN THE INFECTIOUS DISEASES 239 taken with the eggs if desired, or an ordinary helping of meat or fish may be substituted. In the middle of the morning, at 10.30 or 11.30, a glass of milk. Luncheon.-A glass of milk, a helping of fish or a chop or piece of steak or some meat entree, a slice of bread or toast or a roll, half ounce of butter, a potato or a helping of rice, of hominy, or the equivalent. A green vegetable, as spinach or a lettuce or tomato salad, and a dessert of junket, bread pudding, baked custard, or some similar nutritious dish. In place of afternoon tea a glass of milk with a few slices of bread and butter. Dinner.-A glass of milk, a small amount of soup if desired, and if it does not interfere with the appetite, an entree if desired, a good helping of some substantial plain meat, as roast beef, mutton or lamb, or chicken, guinea- hen or turkey, potatoes, or a farinaceous vegetable and a green vegetable, a salad if desired, and dessert and a small piece of cheese. At Bedtime.-A glass of milk. The above works out approximately as follows: Carbo- Food. Protein, Fat, hydrates, grams. grams. grams.

The milk taken at meal time should be drunk at the end of the meal and not at the beginning, so as not to interfere with the appetite. If desired or if deemed necessary, a small amount of liquid nourishment may be taken during the night if the patient awakens. As a rule, however, it is well to give the stomach a full night's rest. In severe cases, where only small quantities of liquid or semisolid food are taken, the intervals should be shortened to every two or three hours. Diets for the poorer classes of people should be so arranged as to be more or less like the diet to which they are accustomed, both in composition and price. This means that the dietary is more bulky, contains more car- bohydrates and less fat. The additional protein and car- bohydrate and fat can be conveniently and cheaply added in a quart of milk, meat, beans, peas or lentils, and butter. Where price is a very great item, skim milk may be used in part or entirely, and oleomargarin substituted for the butter. Beans, hominy, cornmeal, lentils, dried peas, and similar articles of diet may be used in large quantities, and the cheaper cuts of meat substituted. There is not always any real economy in cheaper cuts of meat, as some of them contain comparatively little nutriment. In cities where there are markets, by purchasing just before the market closes, odds and ends of various cuts may be bought at very low prices and to greater advantage from the standpoint of food value than cheaper cuts. Feeding Advanced Cases.-In advanced cases patients may generally be permitted to select their diet. These patients can often eat hearty meals with a relish and apparently digest them without difficulty. As a rule, FEEDING IN THE INFECTIOUS DISEASES. 241 they must be light, liquid or semi-solid. The same prim ciples may be applied here as in feeding fever cases, with the exception that the patient's desires should, sc far as possible, be gratified. Gastric Irritability.-This is very troublesome in some cases. The patient should be instructed not to swallow his sputum. If the attack is severe, easily digested liquid food should be given. Peptonized milk, kumiss, and the predigested beef preparations are of value. If there be continued irritability and the patient becomes unable to retain his meals, marked relief is fre- quently afforded by feeding with a stomach tube. Fever.-Tuberculosis patients with fever should be fed much according to the general rules given for fevers in general. If the digestion is not disturbed and the appetite is good easily digested solid food may be allowed. If the solid food does not agree the patient should be placed upon a liquid diet. Forced Feeding (Suralimentation). - Debove discovered that food introduced by means of a stomach tube was often retained when it would otherwise be re- jected. This method is used in gastric irritability and also where the patient is unable to take sufficient food owing to loss of appetite and disgust for food. Diet in Sanatoriums.-The following diet list in use at the King Edward VII. Sanatorium gives a very good idea of the average diet used in institutions for the tuber- culous : 242 DIETETICS FOR NURSES. Diet jor Consumptives. (Standard diets in use at the King Edward VII.

Women.-Proteid, 126 gm.; fat, 160 gm.; carbohy- drates, 220 gm.; calories, 2814. CHAPTER XI. DIET IN DISEASES OF THE STOMACH. Attention has been called by McCarrison to the fact that faulty food is an important factor in the production of gastro-intestinal disorders of civilized human beings. As an evidence of this statement, he points to the in- cidence of these disorders in civilized countries and the comparative absence in those races living under more natural conditions. In diseases of the stomach the selection of a proper diet is often of more importance than the choice of drugs. No absolute dietetic regulations can be formulated in this class of diseases, but it is important to regulate the food in conformity with the particular disease with which the patient is affected, and also to consider the individual tastes and peculiarities of the patient; even in the regu- lation of a diet in any special disease of the stomach, changes are often rendered necessary; these must be made gradually and according to the patient's power to digest the food. Food is said to be easily digestible when it produces no gastro-intestinal discomfort, is passed from the stomach into the intestine at a normal rate of speed, and is easily absorbed. Under normal conditions the digestibility of foods is easily ascertained, for the functions of the stom- ach being normal, the effect of the food upon the func- tions can readily be determined; in the various gastric disturbances, however, this problem is more difficult. In determining the diet for a special gastric disturbance two points must be borne in mind : first, the power to increase the nutrition of the patient; and secondly, the necessity of giving food in a digestible form, so as to lessen the work of the stomach. Leube has devised a scale of the various articles of food, given in the order of their digest- 244 DIET IN DISEASES OF THE STOMACH. 245 ibility. The scale forms the basis of the well-known Leube "ulcer diet." Leube'S Diet Scale.-Diet I.-If the digestion is very much reduced the following articles of food are most easily digestible: bouillon, meat solution, milk, raw or soft-boiled eggs. Diet II.-Somewhat less digestible than Diet I. are the following articles of food: boiled calf's brain, boiled thymus, boiled chicken and pigeon. The different forms of meat are enumerated in the order of their digestibility. Gruels, and in the evening milk mushes made with tapioca and white of egg, may also be placed in this list. The majority of patients can digest boiled calves' feet in addi- tion to the various meat foods already enumerated. Diet III.-If Diet II. is well borne, Diet III. may be given. This consists in adding cooked or raw beef to Diet II. Leube gives the following method of preparing beefsteak, and believes that beef cooked in this way is very easily digested : The meat should be kept for some time and is then scraped with a dull spoon; in this way a pulp is obtained, consisting only of the delicate parts of the muscle, and not containing any of the tough, hard, and sinewy portion. This pulp is roasted in fresh butter. Raw ham is also to be recommended. In addition to meat a small quantity of mashed potatoes may be given, some stale wheat bread, and small amounts of coffee or tea with milk (cautiously). Diet IV.-This list is so arranged that if the patient can digest the articles of food mentioned under this head for some time he can then begin with his usually accus- tomed diet: Roast chicken, roast pigeon, venison, par- tridge, roast beef, medium to raw (particularly cold); veal (from the leg), pickerel, boiled shad (trout, even when young, is very difficult to digest), macaroni, bouillon with rice. Small quantities of wine may be taken one 246 DIETETICS FOR NURSES. to two hours before eating; gravies are contra-indi- cated. Young and finely chopped spinach is allowable; other vegetables, such as asparagus, may be tried cau- tiously, although Leube considers this a risky procedure. After this fourth diet the patients are allowed to take a more liberal diet, but the increase should be gradual. They should refrain from eating vegetables, salads, preserves, and fruits for some time ; and when they are resumed a baked apple is the first of these articles to be eaten. Beaumont's Table.-This shows the mean time of digestion of the different articles of diet-naturally, in the stomach, and artificially, in vials, on a water-bath. The proportion of gastric juice to aliment in artificial digestion was generally calculated at I ounce of the former to I dram of the latter, the bath being kept as close to the natural temperature-ioo° F.-as practi- cable, with frequent agitation.

Penzoldt has devised the following table giving the digestibility of food. He experimented on normal cases, achieving his results by means of the stomach tube, by determining the progress of digestion and the exact time at which the stomach was entirely empty after eating a certain quantity of a special food. The table shows the period of time it takes a given quantity of food to leave the stomach: One to two hours : 100-200 gm. pure water. 220 gm. carbonated water. 200 gm. tea, alone. 200 gm. coffee, alone. 200 gm. cocoa, alone. 200 gm. beer. 200 gm. light wines. 100-200 gm. boiled milk. 200 gm. meat broth, alone. 100 gm. eggs, soft.

Penzoldt has also constructed a series of four diet lists based on the length of time at which various foods leave the stomach, depending upon their mode of preparation and on other qualities of the food. They agree in the main with Leube's diet lists, but are more complete and exact. These diet lists are utilized in the treatment of diseases of the stomach requiring a gradual change from the most digestible form of liquid food to solid foods more difficult of digestion. Ulcer of the stomach may be cited as an example. The first list is followed for ten days; the second, for the succeeding ten days ; the third, for the following eight days, and the fourth, for fourteen days.

DIET IN DISEASES OF THE STOMACH. 253 These tables of Penzoldt are valuable as a basis for the selection of food in gastric disturbances. In these cases it is important that the food be quickly dissolved in the gastric secretion, that it be readily absorbed, that it be neither fermented nor decomposed while being digested or absorbed, and that the entire process be in- attended with discomfort. It must be borne in mind that the digestibility of food varies widely with the individual taste, for no matter how digestible a food may be, if it is unpalatable it will not be digested properly. In general it may be said: First, that in acute conditions the food should be of such a character that the stomach should be spared as much work as possible; second, in chronic disturbances it is important to supply sufficient quantities of nourishment in an easily digestible form, so as to maintain the body weight so far as possible. In deter- mining the quantity of food that is necessary during twenty-four hours, the amount is estimated in calories of heat. As is well known, a human being at rest requires 35 calories per kilo of weight; whereas while he is per- forming light work he requires 40 calories. In order, therefore, to determine the exact amount of nourishment, it is only necessary to know the weight of the individual. Inasmuch as the proteins can be replaced in a measure by the carbohydrates and fats, an interchange of any of these three food elements can be made according to the patient's condition. When the weight of the person is known, it is an easy matter to determine whether the amount of nourishment given is sufficient to maintain the body weight. It is well also to weigh every patient suffering with a stomach disorder when treatment is first inaugu- rated, and to repeat this from time to time, in order to determine whether the patient is gaining or losing flesh. 254 DIETETICS FOR NURSES. The diet must be considered from the standpoint of the gastric secretion; there may exist, on the one hand, the condition of oversecretion of acid; on the other, lessened secretion or absence of acid. In cases of oversecretion an abundant protein diet is indicated, inasmuch as the excess of hydrochloric acid is neutralized by this class of foods. Ordinarily, the pro- teins that are best adapted for patients suffering from oversecretion of acid are the red meats and eggs, whereas the carbohydrates must be given in the most easily digestible form. In cases in which there is a diminution of the gastric secretion the protein foods are digested with difficulty, whereas the carbohydrates are more easily digested. In this condition, therefore, only very tender meats, prefer- ably scraped, are to be given; whereas such easily digestible vegetables as spinach, asparagus, mashed pota- toes, and farinaceous foods may be eaten in quite large quantities. In both conditions of increased and dimin- ished secretion of acid a reasonable amount of fat must be eaten, preferably in the form of good butter. The diet in muscular disturbances of the stomach depends greatly upon whether an excess or a deficiency of gastric juice is secreted; if there is an increase, an excess in protein food gives the best results; if, on the other hand, there is a diminution of this secretion, pro- tein food must be given the patient in the most easily digestible form. The carbohydrates and the lighter vege- tables may be given in somewhat larger proportion. In both conditions the ingestion of fluids should be reduced so far as possible. Normally, the appetite is a fair indication of the num- ber of calories of heat that may be required; in condi- tions of gastric disorder, however, this is not the case; DIET IN DISEASES OF THE STOMACH. 255 these patients lose their appetite, and consequently often take insufficient nutrition. In those instances in which the gastric disorder is somewhat protracted and accom- panied by great loss of weight and in which the patient takes insufficient nourishment, it need only be borne in mind that such a patient, resting quietly in bed, re- quires fewer calories than a patient who is not resting. This plan may therefore be used with advantage in the treatment of many patients suffering from disorders of the stomach. Liquid Foods in Gastric Disorders.-In these cases, in which it is necessary to spare the stomach as much work as possible, milk is the food that is usually most easily borne. In order to supply a sufficient num- ber of calories it must be taken in large quantities, fre- quently diluted with lime water or barley water in order to add to its digestibility, or flavored with coffee, tea, or cocoa to lend variety and add to its palatability. In those cases in which milk is not well borne, buttermilk, whey, kumiss, and kefir may serve as substitutes. Among the other forms of fluids that may be given are broths (chicken, beef, mutton), bouillon, beef tea, and meat juice. Of these, meat juice is most nutritious. Gelatinous Forms of Food.-Gelatinous articles of food, as gelatin, calves' feet, etc., are easily digested and readily absorbed. Meats.-The digestibility of meat can be increased by chopping, beating, grinding, scraping, etc. Eggs.-The digestibility of eggs depends upon their mode of preparation; raw and soft-boiled eggs are usually the most easily digestible forms. Fish.-In regard to fish, those containing but little fat are to be recommended for patients suffering from gastric disturbances, such as shellfish, pike, trout, carp, and halibut. 256 DIETETICS FOR NURSES. Carbohydrates.-The number of vegetables from which selection may be made is large. The secretion from the mouth and intestines play an important role in the digestion of these substances. They should be masti- cated thoroughly. In those cases in which there is danger of fermentation they should be given with caution. The best form in which to give amylaceous food is in the form of zwieback, toast, stale wheat bread, tapioca flour, oatmeal, etc. Leguminous foods contain a considerable amount of protein, much of which, however, is not absorbed. They are apt to give rise to considerable fermentation. Pota- toes are best given mashed or baked. Cabbage contains much cellulose and should be omitted from the diet of all patients suffering from stomach disorders. Fruits are of slight nutritive value, but give a relish to other foods and increase intestinal peristalsis. Fat is to be recommended because of its tendency to increase the weight of the patient, and also because of its high caloric value. Some observers claim, however, that it acts as an irritant to the stomach. It is true that many patients find that fat meat, greasy gravies, etc., give rise to indigestion, and often to nausea and vomiting. Much depends, however, on the mode of preparation. A considerable amount of fat may be given in the forms of fresh butter spread on wheat bread or toast. Certain forms of chocolate contain quite a large percentage of fat, and on this account are very nutritious. Of these, Mehring's Vigor Chocolate is to be especially recom- mended. Olive oil has recently been recommended in the treatment of certain gastric disorders. Special Factors Bearing on the Diet in Pa- tients Suffering from Gastric Disturbances.-i. Von Noorden demonstrated the fact that the intestine DIET IN DISEASES OF THE STOMACH. 257 will vicariously perform the work of the stomach in con- ditions in which the secretion of the latter is lost. The point to be borne in mind is that even in cases in which the secretion of the stomach is lost entirely, the intestine may assume this function of the stomach. 2. In those cases in which it is necessary to spare the stomach, as when food can not be digested or is vomited, either predigested foods may be utilized or foods may be administered through channels other than the stomach. Among the artificial predigested preparations are the albumoses and peptones, as somatose and nutrose. For the various methods of feeding the reader is referred to the sections on Rectal Feeding, Subcutaneous Feeding, etc. 3. The following rules for eating should be carried out: (a) Food should be thoroughly masticated; this is especially important in those cases in which there are marked gastric disturbances. (£) The meals should be taken at regular intervals and in moderate quantities, according to the nature of the gastric disease. (z-) The temperature of the food is also an important factor in the treatment of gastric disturbances ; as Uffel- mann has pointed out, the food should be taken at a tem- perature between 98° and ioo° F. The ingestion of very hot food is believed to be a frequent cause of ulcer of the stomach. On the other hand, Wegele attributes the dys- pepsia of many Americans to the taking of ice-cold water and other cold drinks. (<7) The question of rest or exercise after eating is one that is of considerable importance to those suffering from gastric disturbances. It is generally admitted that violent exercise should not be indulged in after eating. From the authors' observations, it appears that in con- 258 DIETETICS FOR NURSES. ditions of gastric disturbances accompanied by increased or decreased acidity and in muscular disturbances of the stomach, the gastric digestion is improved during rest, but impaired by sleep, after meals. Special Cures in the Treatment of the Dis- eases of the Stomach.-Among the special forms of treatment recommended in gastric disturbances may be mentioned the rest cure, the milk cure, the grape cure, and forced feeding or gavage. The rest cure, first devised by Weir Mitchell, plays an important role in the treatment of stomach disorders. This treatment is especially useful in cases of nervous stomach disorders. It is also useful in the treatment of ulcer, gastritis, and other conditions. The rest treat- ment in gastric disorders should be carried out for from six to eight weeks. The patient should be confined to bed a large part of this time and given a varied diet, food being supplied every two to three hours. Boas advises that instead of the large quantities of milk usually pre- scribed, the patient will do better if given J to I liter of cream daily in portions of 150 to 200 c.c. In addition to the protein food he advises a diet rich in carbohydrates and fats. The results that follow this plan of treatment are often marvellous. For a further consideration of the method and plan of conducting the rest treatment syste- matically, the reader is referred to the section dealing with that subject. Milk Cure.-The underlying principle of the milk cure consists in the ingestion of large quantities of milk, either alone or together with other foods. Under normal con- ditions, when taken alone in large quantities-say three liters a day-milk does not suffice as a food; in certain digestive disturbances, however, milk given alone for a time forms a useful food and allows the stomach to regain DIET IN DISEASES OF THE STOMACH. 259 its normal tone and functions. Milk is especially useful in the treatment of ulcer of the stomach and in certain forms of chronic gastritis; it is particularly useful in the secondary forms of gastritis, as those depending upon tuberculosis, anemia, etc. In some cases of nervous dys- pepsia milk cures sometimes effect remarkable results; whereas in others milk disagrees and, as a consequence, the milk cure can not be undertaken. When there is a diminution or an absence of acid in the stomach, milk is usually not well borne. It is also contra-indicated in severe cases of muscular relaxation of the stomach and in intestinal conditions accompanied by extreme flatulence and chronic diarrheas. When milk is given in large quantities in addition to other foods, it is more frequently better borne and is less apt to disagree. One of the disadvantages of the milk cure is the obstinate constipation the milk is apt to in- duce. Milk can often be rendered more digestible by the addition of barley water, lime water, milk of magne- sia, and the like, or small quantities of coffee, tea, or whisky may be added to it. When milk disagrees, cream, buttermilk, kefir, kumiss, or matzoon may be given as a substitute for it. (See Milk Cure.) Forced Feeding or Gavage.-This method consists in introducing milk, eggs, and meat extracts into the stomach by means of the stomach tube. Grape Cure.-In this form of treatment the patient lives exclusively upon grapes; it is especially useful in obese individuals, in whom it is important to diminish the weight; in anemia, girls suffering with dyspepsia, and in certain cases of nervous dyspepsia. The Fast Cure.-Prolonged fasting has been ad- vocated in the treatment of various affections of the gastro-intestinal tract, thus representing the employ- 260 DIETETICS FOR NURSES. ment of rest in the treatment of diseases of other portions of the body. The total fasting may be continued for some days. This method has been utilized in the treat- ment of gastritis, hyperacidity, and ulcer of the stomach. DIET IN DYSPHAGIA (DIFFICULTY IN SWALLOWING). Dysphagia may be due to any obstruction in the mouth, pharynx, or esophagus. The difficulty and pain induced by swallowing must be obviated by lessening as much as possible the efforts at swallowing; for this reason food must be given in a concentrated form, and only in a liquid or semi-solid state; milk, egg albumin, and the concentrated liquid beef preparations are espe- cially useful in this condition. In those cases in which food can not be swallowed in sufficient quantities the patient must be fed through the stomach tube. In this way broths, gruel, milk, and the like can be passed into the stomach. DIET IN ACUTE GASTRITIS. Oser has said that " every case of acute catarrh of the stomach has a natural tendency to heal of its own accord unless a chronic form is produced by a mistaken diet or wrong medication." It is a generally admitted fact that in the treatment of this condition the diet plays the lead- ing role. The first step in the treatment consists of securing absolute rest for the stomach and a total absti- nence from food for at least twenty-four hours. This procedure is sometimes very difficult to carry out, for many patients believe that food is necessary for them, and that they can secure relief more quickly by taking nourishment. The nausea and vomiting which are present in more or less degree in this condition, and which are aggravated by the taking of food, will soon convince the DIET IN DISEASES OF THE STOMACH. 261 patient of the necessity of abstaining from food. The thirst is, however, so severe in these cases that patients may be allowed to rinse the mouth with water frequently, to retain tiny bits of ice in the mouth, or even to drink very small quantities of carbonated waters. With this plan of treatment recovery generally follows in two or three days. After the first twenty-four hours feeding may be begun by giving cautiously small quantities of milk diluted with lime water, broths, and egg albumin; these can gradually be increased in quantity, and during the next day or two boiled chicken, sweetbreads, scraped beef, in addition to toast, may be added. The authors are accustomed to prescribe the following diet about the second or third day after an attack of acute gastritis: Calories. 7 A. M.: 150 gm. milk with lime water 101 9 A. M.: 100 gm. egg albumin flavored with orange or lemon juice, 53 11 A. M.: 150 gm. broth with egg 84 I p. M.: 150 gm. milk with lime water 101 3 P. M.: 5 gm. Armour's soluble beef in water 10 5 P. M.: 100 gm. egg albumin flavored with orange or lemon juice, 53 7 p. M.: 150 gm. milk with lime water Jtoi 503 After the third day the diet is increased as follows : Calories. 7 A. M. : 150 gm. milk (101) with 70 gm. toast (182) 283 9 A. M.: 2 very soft-boiled eggs 160 11 A. M.: 200 gm. bouillon with 1 egg 85 I p. M.: too gm. rice cooked in milk 177 70 gm. toast 182 3 p. M. : 100 gm. egg albumin (53) with 50 gm. crackers (187) . 240 5 P. M.: 150 gm. milk with 70 gm. toast . • • 283 7 p. m. : 100 gm. egg albumin flavored with orange or lemon juice, 53 1463 1 In comparing these diet lists slight discrepancies in the calorie values of the foods will be noted. These differences have arisen from some authors using the calorie values of raw foods, while others have computed the values of cooked foods. In the diet lists given by the authors, calorie value of foods as prepared for the table are given. 262 DIETETICS FOR NURSES. DIET IN CHRONIC GASTRITIS. The dietetic treatment of chronic gastritis is of far greater importance than the treatment of this disease by the use of drugs. The diet must be varied according to the stage of the disease. The most easily borne forms of food are liquids, such as broths; unfortunately, these foods do not furnish sufficient nutriment to sustain the patient. Their nutritive value may be increased by the addition of beef extracts, eggs, barley and rice, peptones, somatose, etc. The diet should vary according to the character of the gastritis; in those cases in which the gastric secretion has entirely or almost entirely disappeared, protein food is digested with great difficulty; it must therefore be given in the most digestible form; of these foods, scraped beef, stewed beef, stewed chicken, broiled steak, and boiled sweetbreads are especially to be recommended. Vegetables should also be given in the most digestible form, best as a mush. Milk is useful in most cases; occasionally, however, it is not well borne; when this is the case, it can be made more agreeable by adding small quantities of rice, potatoes, or cocoa to it, or kefir, kumiss, or matzoon may be substituted for it. In those conditions in which considerable acid still remains in the stomach, meats in various forms are very acceptable ; to this list may be added fish and eggs; vegetables, such as mashed potatoes, spinach, mashed carrots, especially in the form of purees, are to be recommended. In all in- stances fat should be given in an easily digestible form- as good butter, cocoanut butter, or Mehring's Vigor Chocolate. It is impossible to formulate exact rules as to the number of meals that should be eaten and the DIET IN DISEASES OF THE STOMACH. 263 quantity that should be taken at each meal; in a general way, small frequent meals are best borne. Water should be taken in small quantities between meals. Alcoholic stimulants or any strong stimulants should, as a rule, be omitted; when utilized, they should be given in small quantities and best diluted with mineral waters. Salt and spices may be allowed occasionally in small quantities. The authors have found the following diet list useful in cases of chronic gastritis: Calories. 8 A. M.: 200 gm. milk flavored with tea 135 60 gm. stale bread (154) with 40 gm. butter (326) . . 480 1 soft-boiled egg 80 10 A.

Dilatation of the stomach may be either acute or chronic. The acute form is but rarely seen. Chronic dilatation results either from a narrowing of the pylorus or from weakness of the muscular walls of the stomach. This latter form may be seen in diabetes, the insane, and in beer drinkers, as well as under many other con- ditions. 264 DIETETICS FOR NURSES. In the dietetic treatment of dilatation of the stomach, it must be remembered that fluids are badly borne, and must, therefore, be given only in very small quantities- not over I to ij liters a day. The fluids that are per- missible are milk, cream, coffee, tea, and bouillon, all in small quantities. The thirst that accompanies this dis- ease may be relieved by allowing the patient to suck bits of ice or by giving rectal injections of water or normal salt solution. Since nutrition is usually very faulty in this disease, nutrient enemata must frequently be em- ployed. When milk is administered, such substances as tapioca and rice should be added. Egg or concentrated meat extracts should be added to bouillon to increase its nutritive value. Meats should be given only in the most digestible forms; of these, stewed chicken, boiled sweet- breads, calves' brains, and scraped beef are to be pre- ferred. Vegetables, such as carrots, spinach, peas, pota- toes, should be administered in the form of purees. Bread should be eaten stale; wheat bread or toast is best. Stewed fruits, such as stewed prunes, and baked apples are also permissible. Since fats are apt to cause fermentation, butter should be allowed only in quite small quantities. Alcohol is not to be recommended in this condition. Strong spices should always be avoided. The special feature of the treatment consists in giving frequent concentrated meals. Patients with dilatation of the stomach should be cautioned against visiting watering- places for the purpose of drinking the waters.

Since atonic dyspepsia is frequently caused by inju- dicious and too rapid eating, persons with feeble digestive powers should exercise especial caution to eat slowly, masticate thoroughly, and avoid indigestible food. Per- sons suffering from atonic dyspepsia should eat small quantities of food at frequent intervals. Since water is not absorbed in the stomach to any extent, it is advisable that the quantity of fluids taken should not exceed liters a day; this amount should include all fluids- coffee, tea, soups, etc. If the thirst is very great, enemata of water or nutrient enemata may be administered. The use of milk in large quantities, as has been recom- mended, is not generally to be advised when the patient is able to go about, since the weight of large quantities of milk may overdistend the stomach; when, however, a rest cure is instituted, milk is commonly well borne, even in very large quantities. The diet in atonic dyspepsia varies according to the nature of the gastric secretion. 266 DIETETICS FOR NURSES. In cases in which there is an excess of acid a liberal meat diet, consisting especially of chicken, beef, mutton, or ham, is to be recommended; fish, eggs, hard- and soft- boiled, are also permissible; the vegetables should be selected with care; carrots, peas, beans, and cauliflower may be given, but must be mashed and strained so as to rid them of cellulose; potatoes, rice, and grits may also be allowed. Butter is the form of fat best suited to this condition. Alcoholic stimulants are, as a rule, not well borne, and their use should be prohibited; in a limited number of cases alcohol in the form of a light wine acts as a stomachic and may be prescribed. In those cases in which there is an absence or a dim- inution of acid in the gastric secretion, the lighter forms of meat, such as the white meat of chicken or fish, sweetbreads, stewed chicken, or raw scraped beef, should be allowed; vegetables, on the other hand, must be given in somewhat larger quantities. The treatment of the chronic constipation accompany- ing atonic dyspepsia, since it is one of the most constant symptoms, requires special mention. In the treatment of this condition the main reliance must be placed on the diet. Such forms of foods should be given as will, in the course of digestion, produce substances that excite in- testinal peristalsis; among these foods may be mentioned Graham bread, certain vegetables, such as carrots, beans, tomatoes, peas, and turnips, macaroni, stewed and raw fruits, buttermilk, honey, and cider. This form of diet will often overcome the constipation without the aid of drugs. (For a more extensive consideration of the die- tetic treatment of chronic constipation, the reader is referred to the section dealing with that subject.) The following list has been used by the authors in the treatment of atonic dyspepsia: DIET IN DISEASES OF THE STOMACH. 267 Calories. 7 A. m. : 40 gm. orange juice 88 8 A.

Much can be done by a carefully selected diet to pre- vent the onset of an ulcer of the stomach. As soon as the very first symptoms become manifest, the patient should be placed upon an absolute milk diet. The tem- perature of the food should be regulated, so that it be not given too hot nor too cold. Boas divides the treatment of ulcers of the stomach into several stages: Stage of Hemorrhage.-In this stage Boas advises absolute rest in bed; the patient not even being allowed to arise for purposes of defecation or urination. No nourishment whatever should be given by the mouth. In robust individuals even nutrient enemata may be omitted. If the patient is weak or in feeble condition, feeding by the rectum may be instituted. (See the sec- tion on Nutrient Enemata for the method of preparation 268 DIETETICS FOR NURSES. and utilization of this mode of feeding.) Only two or three nutrient enemata are to be given daily. Boas carries out this plan for three or four days. After this he gradually begins mouth-feeding, the nourishment con- sisting exclusively of fluids given at a temperature of 98° to ioo° F. He prefers milk diluted with lime water, with tea, or with coffee. In addition he permits beef tea, freshly expressed or artificial beef juice, and egg albu- min. The carbonated waters, such as Vichy, are also useful. After the first week Boas begins the regular Leube and v. Ziemssen ulcer treatment, which he conducts as follows : The patient is given a one-fourth liter of Carlsbad water, which he drinks in bed morning and evening. Hot-water applications are placed on the abdomen. The diet during this stage consists mainly of milk in addition to other fluids. If the patient is very weak, nutrient enemata may occasionally be given. In the treatment, beginning with the third and continu- ing during the fourth week, Boas permits the patient to recline on a couch and continues the use of the Carlsbad water, which should be given for four weeks from the time it is first taken; he advises that the diet still consist mainly of milk, although he now permits the addition of soaked zwieback, scalded crackers, and soft rolls. Meats (sweetbreads, brains, meat balls), fish (perch, oysters in small quantities), in addition to the light red wine and carbonated waters, are also allowed. After the fourth week, if the patient is doing well, Boas adds from 50 to 200 gm. of mashed potatoes, stewed fruits, and vegetables, such as spinach, carrots, peas, and turnips, in the form of purees, to the diet pre- viously given. The meats (broiled steak, chops, and roast beef), if well cooked, can finally be given more DIET IN DISEASES OF THE STOMACH. 269 liberally. According to Boas, the patient should avoid raw fruit, acid and highly seasoned foods, and also very hot and very cold drinks for many years. Even in those cases in which there has been no hemorrhage, Boas never- theless advises the rest treatment. It is generally admitted that the rest cure is the only satisfactory plan for treat- ing cases of ulcer of the stomach. Leube and Penzold-t have devised dietaries for these cases ; these have been given elsewhere (see p. 25i). The first dietary should be followed for ten days; the second, for the succeeding ten days; the third, for about eight days. The severity of the condition in each case must, of course, determine the length of time during which each dietary must be continued. In all instances milk seems to be the most useful form of food during the first weeks of this rest treatment. Occasionally milk does not agree, and sub- stitutes must be given in its stead. Of these, buttermilk, kefir, matzoon, and kumiss or yoghurt are especially to be recommended. In order to increase the food-value of milk, cream may be added, and the following calculation of Strauss may be utilized in order to estimate this increased value: Calories. A. loo gm. full milk 70 B. 75 gm. full milk with 25 gm. cream 115 C. 50 gm. full milk with 50 gm. cream 185 D. 25 gm. full milk with 75 gm. cream 205 E. 180 gm. cream 250 There are, therefore, of each (milk, milk and cream, and cream) in the half liter: Calories.

He bases his conclusions on the fact that since ulcer of the stomach is most frequently accompanied by superacidity and also by an enfeebled condition, it is best to give protein food early to overcome the acidity as well as to build up the system. The accompanying table illustrates his method of feeding: Day after last hematemesis .1234567 8 9 10 11 12 13 14 Eggs 23456 7 8 8 8 8 8 8 8 8 Sugar, gm. ... 20 20 30 30 40 40 50 50 50 50 50 50 Milk, c.c. . . . 200 300 400 500 600 700 800 900 1000 1000 1000 1000 1000 1000 Raw scraped beef, gm. . . 352X352X352X352X352X352X352X352X35 Milk cooked with rice, c.c. 100 xoo 200 200 300 300 300 300 Zwieback, gm. . 20 40 40 60 60 80 xoo Ham (raw), gm. 50 50 50 50 50 Butter, gm. . . 20 40 40 40 40 Calories . . . .280420637779955x135 1588 1721 2138 2478 2941 2941 3007 3073 In the Lenhartz cure, absolute rest in bed for at least four weeks is maintained. An ice-bag is placed on the abdomen, and left on more or less continually for two weeks. On the first day, even though there be hemat- emesis, 200 c.c. of iced milk are given in teaspoonful doses together with two raw, ice-cold, beaten up eggs. The eggs are beaten up with sugar, and they are kept cold by placing the cup containing them in a dish filled with ice. The milk is increased every day 100 grams, and one additional egg added; on the ninth day the patient is given I liter of milk, and the quantity is not increased; on the sixth day raw scraped beef is added, and the quantity is doubled on the following day; on the seventh and eighth days the patient is given some well-cooked rice and zwieback (softened), and on the tenth, raw ham and butter. The following table, arranged by us, has been found exceedingly serviceable in treating cases of ulcer, ac- cording to the Lenhartz method. DIET IN DISEASES OF THE STOMACH. 271 During the first and second days of treatment, instead of giving the food at two-hour intervals it is given very frequently in teaspoonful doses, and ice cold. In fol- lowing these diet tables, it is only necessary to remember that for practical purposes 4 drams of milk sugar are about one tablespoonful. i ounce of raw beef is about one tablespoonful. 5 drams of zwieback are about two slices. 5 drams of butter are about one tablespoonful.

DIET IN DISEASES OF THE STOMACH. 275 SIPPY DIET. Only recently Sippy has evolved a method of treating peptic ulcer which seems likely to replace all other meth- ods of treatment. The treatment consists in protecting the ulcer from the acid corrosion until it has healed by shielding it from the corrosive effect of the gastric secre- tion. He accomplishes this by maintaining a neutralization of all free HC1 from early in the morning until late at night. This is effected by frequent feedings and the use of alkalis given frequently. The patient remains in bed for three to four weeks. Three ounces of a mixture of equal parts of milk and cream are given every hour from 7 A. M. to 7 p. M. After two or three days soft eggs and well-cooked cereals are gradually added until in ten days the patient receives 3 ounces of milk and cream mixture every hour, 3 soft-boiled eggs and 9 ounces of a cereal each day. Cream soups of various kinds, vegetable purees, and other soft foods may be substituted now and then as desired. Powders of magnesia and soda and bismuth and soda are given between the feedings to neutralize the acid secretion. The following diet list presents our method of feed- ing during the Sippy cure. Either sodium bicarbonate with calcined magnesium or sodium bicarbonate with calcium carbonate are given alternately on the half hours from 7.30 A. M. to 10.30 P. M. 276 DIETETICS FOR NURSES. Hour.

HEMORRHAGE FROM THE STOMACH. As soon as hemorrhage from the stomach occurs the patient should be put to bed and not allowed to rise. A light ice-bag should be placed over the region of the stomach, and no food or drink whatever should be allowed; in order to quench the thirst, small quantities of ice may be given the patient to suck. Nourishment must be en- tirely by the rectum; but even this is usually unneces- sary for the first few days. In order to combat the weakness following great loss of blood, salt solutions may be injected into the rectum, or if the patient is very weak, coffee, meat juice, or whisky may be added to the enema. In very grave cases salt infusions must be resorted to and tranfusions of blood may become necessary. In the dietetic treatment of cancer of the stomach milk forms the most important article of diet. The more easily digestible forms of meat, such as sweet- breads, scraped beef, calves' brains, and stewed chicken, are permissible. In this disease there is usually a distaste for meat, and fish may be substituted for it; of these, boiled mackerel, rock, haddock, or trout are to be recom- mended. Of the vegetables, mashed potatoes, spinach, carrots, peas, beans, cauliflower, if mashed and strained so as to rid them of cellulose, are admissible; rice, farina, and corn starch with milk are also valuable forms of food. Milk with tea, coffee, or cocoa, or wine or whisky may be given for the thirst. Fluids should, however, be taken in small quantities at a time. In order to supply the necessary quantity of fat, butter or Mehring's Vigor Chocolate is to be recommended. In these cases it is often important to promote the general nutrition by means DIET IN CARCINOMA OF THE STOMACH. DIET IN DISEASES OF THE STOMACH. 281 of rectal alimentation. In cases of cancer of the stomach too abundant a diet should not be insisted upon, as at best but little can be gained by this method of treatment. When the growth is at or near the cardiac portion of the stomach, the diet should be such as will prevent so far as possible any irritation of the diseased esophagus and stomach. Solids should therefore be avoided. Milk is the food that is usually best borne in this condition. The authors have found the diet list given below useful in many cases of cancer of the stomach: Calories, 8 A. M,: 150 gm. milk with tea 100.0 50 gm. toast 130.0 io A.

Panopeptone 57.5 2024.5 DIET IN NERVOUS GASTRIC DISORDERS. Nervous Vomiting.-This is often overcome merely by isolation and change of scene. In severe cases patients should be placed in bed; they are best fed on semi-solid or liquid food, since the latter is more easily retained 282 DIETETICS FOR NURSES. than solid food. It should be given in very small quan- tities; scraped beef, eggs, rice, and toast are especially useful. Cracked ice will often afford relief. The most indigestible forms of food are frequently well borne when the most digestible are speedily vomited. In severe cases the patient should be fed for some days exclusively by rectal alimentation. Diet in Nervous Dyspepsia.-In this condition the diet should not be too restricted. Strengthening food, without any attempt at a too rigorous diet, should be prescribed. In those cases in which milk is well tolerated it should be given in large quantities; when it is not well borne, buttermilk, kefir, or kumiss may be substituted for it. The patient's appetite should be humored, and he should be allowed to eat any food he can digest. Alco- holic stimulants should be prohibited, or given only in very small quantities. In severe cases a well-conducted rest cure will produce the best results. Diet in Hyperacidity.-By the term "hyperchlor- hydria" is meant an increase in the secretion of muriatic acid in the stomach. In the treatment of this condition the main object is to prevent this increase in acid; this is best accomplished by regulation of the diet. All irri- tating fluids, such as acids, including organic acids, as acetic (vinegar), citric, and tartaric acids, spices or con- diments (pepper, mustard, vinegar), should be avoided, and the use of all strong alcoholic beverages and of hard substances, which are apt to irritate the stomach, such as nuts, should be interdicted. Food must be thoroughly masticated, and should be taken neither too cold nor too hot. The class of foods that seem to be best suited are the proteins, since they combine with and, therefore, neutralize the excess of acid; for this reason foods con- taining an abundance of protein, such as eggs, meat, DIET IN DISEASES OF THE STOMACH. 283 and fish, may be given quite freely. The large amount of extractives in meat stimulate the flow of gastric juice, and, therefore, meat should be allowed only when well cooked, so as to remove the extractives. For the same reason raw beef and beef-juice should be avoided in this condition. Carbohydrates should be administered in small quantities and in the most digestible forms. Inasmuch as uncooked meats tend to excite the flow of the gastric juice, they should not be taken in this condition; when meat, however, is well cooked it may be prescribed to advantage in conditions of hyper- chlorhydria. In addition, cocoa and milk are valuable. Farinaceous foods are not well tolerated in this con- dition, and must be given either in a very digestible form or, best, combined with protein food. Only the more digestible vegetables are to be allowed, such as mashed potatoes, spinach, asparagus, peas, and carrots, strained and eaten in the form of purges. Fats tend to lessen the acidity of the gastric secretion, and are, therefore, to be recommended; they are best given in the form of butter, cream, olive oil, and the like. Of the fluids, alkaline mineral waters, such as Apollinaris, Vichy, and Seltzer, are especially useful; the carbon dioxid contained in these waters produces a sedative effect and lessens the secretion of acids. In arranging the diet for patients with hyperchlor- hydria it has been found best in the author's experience, in dealing with patients taking but little nourishment to allow them to eat at frequent intervals; if, however, large meals are consumed, it is advisable to permit only three meals a day, allowing the stomach to rest during the intervals. The following diet has been used with advantage by the authors in cases of hyperchlorhydria: 284 DIETETICS FOR NURSES.

The diet plays quite as important a role in the treatment of diseases of the intestine as it does in the treatment of gastric disorders. In many intestinal dis- turbances, such as acute intestinal catarrh, diarrhea, etc., cures often can be effected by diet alone, when without this mode of treatment the disease might become in- tractable. The diet in intestinal diseases, as in gastric disorders, must be such as will produce no annoying symptoms. The process of digestion in the intestine is exceedingly complicated, and therefore the digestibility of foods in this part of the alimentary tract is most diffi- cult to determine. It has been shown that certain forms of food contain very large proportions of protein matter, but that their absorbability is so slight that their nutritive value is far lower than that of foods containing less protein. Thus, while peas contain considerably more protein (7 per cent.) than does milk (3.7 per cent.), a much smaller proportion of protein is absorbed in the case of the former than in that of the latter; on the other hand, the absorbability depends greatly on the mode of preparation of the food; when vegetables are mashed and then strained, so as to rid them of their cellulose envelopes, they are much more readily absorbed than when eaten with the cellulose. The digestibility of certain foods in the intestine varies 285 286 DIETETICS FOR NURSES. greatly with different individuals. For this reason exact rules can not be formulated in any case, but the diet must be varied according to individual peculiarities. Boas has expressed his opinion on this subject as follows: " i. In a number of intestinal diseases a change of diet is unnecessary or may even be harmful. " 2. In some cases special dietetic restrictions are di- rectly indicated, but these should be as few as possible. " 3. In another series of cases an abundant, heavy, not easily digestible or absorbable diet is indicated. "4. The general aim of our treatment should always be to so manage the case before us that digestion of a normal diet will always occur in the alimentary canal without any subjective or objective disturbances. Under these circumstances only can the case be considered cured." According to their effect on intestinal movements, foods may be divided into three classes: those producing con- stipation ; those producing a laxative effect, and those exerting no especial effect in either direction. In the first class are those foods containing an astringent, such as tannin; among these may be mentioned certain red wines, cocoa, and tea. Rice, tapioca, barley, sago, maca- roni, and potatoes have a tendency to produce constipa- tion in many individuals. Among the laxative foods may be mentioned fruits and certain vegetables, as cucumbers, tomatoes, and cabbage; cider, buttermilk, beer, and the carbonated waters also exert a laxative effect. In the third class, foods that have no especial effect on the intestinal movements, may be placed meats, fish, eggs, toasted bread, and zwieback. It must be remem- bered, however, that certain foods that prove laxative in one individual may be constipating in another, so that no DIET IN INTESTINAL DISEASES. 287 precise rules can be formulated; in each case individual tendencies must be consulted. In severe forms of intestinal disturbances rectal ali- mentation must often be resorted to. For a further consideration of the technic and forms of food to be utilized in this method of feeding the reader is referred to the section on Rectal Feeding. In those cases in which food can not be given either by the mouth or by the rectum, subcutaneous feeding becomes necessary; for this purpose olive oil may be used; one ounce may be injected twice daily under the skin, best in the region of the thigh; in some cases normal salt infusions are indicated. From experimental evidence the conclusion has been reached that it is possible to so vary the diet as to prevent certain undesirable bacterial flora from multi- plying to a great degree. On this account when un- desirable bacteria propagate on both protein and on carbohydrate diet frequent changes in diet are bene- ficial by interfering with the too rapid growth of any one type of bacteria. It has been noted that milk owes its beneficial action to the lactose present. When lactose is taken in liberal quantities together with other food the flora shows evidence of change. Milk and lactose form a most practical and effective diet, therefore, in reducing putrefying types of bacteria. It is now known that the Bacillus acidophilus is the predominant bacterial constituent of the intestinal flora of the breast-fed infant. However, as soon as the milk no longer forms the chief constituent of the child's diet, this organism is found present only to a small degree. In the adult the nature of the intestinal flora is dependent upon the character of the diet. With the normal diet the colon bacillus overpowers the acidophilus 288 DIETETICS FOR NURSES. bacillus, so that it can then only be found with great difficulty. When placed upon an exclusive milk diet, however, the Bacillus acidophilus becomes the pre- dominating organism in the intestine. Rettger and his co-workers have demonstrated that this organism may be implanted in the intestine whereupon the number of colon organisms decrease to a marked degree. This effect is increased by the ingestion of lactose. Extremely bene- ficial results have been obtained by the implantation of the Bacillus acidophilus in the intestine in certain in- testinal affections. Antiputrefactive Diet.-The most important food containing protein and yet acting in an antiseptic way is milk. It has both a high nutritive value, is easily as- similated, and yields a very small amount of products of decomposition. If it produces indigestion, as it does in some instances, this effect can be overcome by the addi- tion of rice, oatmeal, milk of magnesia, or citrate of soda. When milk is badly borne, one finds usually that it ferments too rapidly, and that the intestine is stimulated by the products of decomposition. In most instances milk is the digestible food for pa- tients affected with intestinal disorders. However, when it is not well borne in some instances, it should be given in small quantities together with other food, such as milk soups, mushes, flour-soups, etc. Milk, however, should be given with caution in catarrh of the intestines, and in certain ulcerations of the large bowel. In some in- dividuals kefir or yoghurt must be substituted. Of other preparations the artificial products, such as nutrose and plasmon, are to be recommended. Gelatin is another food which is apt to inhibit the growth of organisms of putrefaction in the intestinal canal, and therefore must be considered a valuable form of nourishment. DIET IN INTESTINAL DISEASES. 289 As the patient improves, other articles of diet may gradually be added, but with great caution. Of these, the carbohydrate foods should be taken in the form of zwieback, crackers, wheat bread (stale). Butter may be given in small quantities. Finally cereals may be al- lowed, with the addition of milk and cream. Sugar should be taken in small quantities; gradually vege- tables may be added, but should be mashed and strained. When eggs are given, they should be taken with caution, inasmuch as patients affected with intestinal diseases at times tolerate eggs badly. Still later on small quantities of broiled minced meats may be added. The coarse shreds of connective tissue found in meats should be extracted. Stewed fruits are permissible, the skins and seeds being first removed. Antifermentative Diet.-By antifermentative diet we especially refer to those forms of carbohydrate food which are least apt to cause fermentation, especially diarrhea. In the treatment of such cases in which car- bohydrate fermentation exists the quantity of carbohy- drate food administered should be reduced in quantity or this article of diet entirely eliminated, and fat and proteins substituted, until the carbohydrate fermentation has disappeared. The protein food is apt to undergo putrefaction, and the carbohydrates, fermentation. Therefore when there is a tendency both to putrefaction and fermentation the diet should consist at first of clear broths, with dry bread or crackers. Then cereals may be added, together with milk. Finally, when this diet is well borne, the more solid foods, in the form of chicken, broiled meats, and butter, may be allowed. Milk should be taken with caution when fermentation exists. 290 DIETETICS FOR NURSES. The management of the diet in intestinal disorders is often difficult. It requires great experience and judg- ment to determine what particular foods should be given the patient and also to know how long they should be continued. It frequently requires great tact and patience on the part of the nurse to see that the directions of the physician are carried out. DIET IN INTESTINAL DYSPEPSIA. In intestinal dyspepsia food should be given frequently and in very small quantities. At first only the liquid forms should be used, such as weak tea, peptonized milk, malted milk, bouillon, and egg albumin; after a few days the patient may gradually be placed on the follow- ing diet: calves' brains, sweetbreads, broiled steak or lamb chops, soft-boiled eggs, boiled fish, such as mackerel or rock; baked potatoes, spinach, asparagus, and stewed fruits. The following list gives the general plan of a diet used by the authors in this condition: Calories. 8 A. M.: 150 gm. milk with tea 101 1 soft-boiled egg 80 60 gm. toasted wheat bread (155) with 20 gm. butter (163) 218 io A.

As in acute gastric catarrh, so also in acute intestinal catarrh the regulation of the diet is probably the most important factor in the treatment of the disease. The patient should be kept in bed; after the bowel has been thoroughly emptied by a cathartic, liquid foods, such as clear broths-at first without and then with eggs-thin gruels, light tea, cocoa cooked in water, and egg albu- min, should be given exclusively for several days. In this condition milk should not, as a rule, be given. When there is extreme thirst the carbonated waters may be allowed, but only in small quantities. The thirst is best relieved by placing bits of crushed ice in the patient's mouth. After the pain and discomfort have disappeared, toast, crackers, stewed chicken, soft-boiled eggs, mashed potatoes, and boiled rice may be added to the diet; indigestible foods, such as raw fruits, heavy vegetables, and fatty and acid foods, should be avoided for a considerable period of time after the catarrh has disappeared. DIET IN CHRONIC INTESTINAL CATARRH. The dietetic treatment in chronic intestinal catarrh depends upon the condition of the fecal movements; these are, in a measure, an index as to the portion of the bowel involved. Cases of chronic intestinal catarrh may be divided into those cases associated with chronic con- stipation, those associated with chronic diarrhea, and those in which diarrhea alternates with constipation. Diet in Chronic Intestinal Catarrh Associated with Chronic Constipation.-In this condition a mixed diet containing, so far as possible, those sub- stances that stimulate the intestinal peristalsis should be prescribed. Astringents and anything that tends to 292 DIETETICS FOR NURSES. produce constipation, such as cocoa, chocolate, tea, red wines, rice, farina, etc., should be avoided. The following foods should be prescribed in cases of chronic constipation : Graham and rye breads with butter, fruit, buttermilk, kefir, cider, beer, fresh vegetables, as cabbage; sour krout, and salads. Fats are especially to be recommended, and honey is also useful. Salts stimu- late the intestinal movements, therefore foods containing salts are indicated in this condition; among this class may be mentioned herring and caviare. Sugar, espe- cially milk sugar, has a marked tendency to increase intestinal movements. Water taken cold or on an empty stomach will also stimulate intestinal movements. Diet in Chronic Intestinal Catarrh Associated with Chronic Diarrhea.-When severe symptoms, such as intense diarrhea and pain, present themselves the patient must be put to bed and kept on a very rig- orous diet; the period of rest may be lengthened of shortened according to the severity of the disease. In moderately severe cases several weeks will usually suffice. Nourishment should be taken in small quantities every few hours; sufficient must, however, be given to main- tain the body weight. All cold drinks or carbonated waters, fruits, cabbage, and salads are to be avoided. The most suitable foods in this disorder are broths con- taining barley, rice, and farina; soft-boiled eggs, sweet- breads, stewed chicken, broiled steak, boiled fish, toast, crackers, baked potatoes, tea, milk (boiled), and cocoa; in many cases port wine is quite useful, as it contains tannin, which acts as an astringent to the bowels. In this condition milk, even when boiled, is often not well borne, and must then be avoided. In conditions of chronic intestinal catarrh in which diarrhea alternates with constipation, the same plan of DIET IN INTESTINAL DISEASES. 293 treatment may be followed as has been described for those cases accompanied by constipation or diarrhea; it is especially important to treat by diet the more prom- inent symptoms, whether it be diarrhea or constipation. Mineral waters are frequently utilized in cases of chronic intestinal catarrh. For cases accompanied by constipa- tion the waters of Marienbad and of Saratoga (Congress and Hathorn Springs) are most beneficial. Where diar- rhea is the prominent symptom, Carlsbad and Vichy are to be recommended. DIET IN DYSENTERY. The diet in acute dysentery is similar to that pre- scribed in acute intestinal catarrh. The patient is put to bed and only liquid foods are administered. Of these the most suitable are bouillon, broth, egg albumin, and tea; gradually, as the condition improves, semi-solids, such as milk toast, rice cooked in milk or broth, gruels of tapioca, etc., may be prescribed. Solid food should be abstained from until a few days after the disorder has abated. In chronic dysentery the food should be given in small quantities at frequent intervals. All coarse, indi- gestible food should be avoided. In other respects the diet is similar to that already given under Chronic Intes- tinal Catarrh. DIET IN ULCER OF THE INTESTINE. The diet in ulcers of the intestine is the same as that for ulcers of the stomach, and the reader is referred for the details to the section dealing with that subject. In cases accompanied by hemorrhage absolute rest in bed must be insisted upon, and rectal alimentation adminis- tered if necessary. In any form of ulcer the diet should 294 DIETETICS FOR NURSES. be non-irritating and easily digestible. Among those foods that may be given are milk, eggs, rice, farina, sago, all forms of broth, especially chicken and mutton broths; sweetbreads, stewed chicken, baked potatoes, mashed potatoes, tea, cocoa, crackers, and toast. DIET IN MALIGNANT GROWTHS OF THE INTESTINE. The medical treatment in malignant growths of the intestine is only an adjunct to the surgical treatment always indicated, and consists solely in treating the symptoms as they arise. The diet should be highly nutritious and at the same time easily digestible; small quantities of food should be given at frequent intervals. Milk, broths, soft-boiled eggs, raw scraped beef, sweet- breads, baked and mashed potatoes, vegetables, such as carrots and peas, that have been finely divided and strained, stewed fruits, toast, and crackers are permissible. DIET IN ACUTE INTESTINAL OBSTRUCTION. The treatment of acute intestinal obstruction, except when due to the impaction of a foreign body, when it may possibly be passed through the bowel, is purely sur- gical. Previous to operation the following dietetic reg- ulations should be carried out: The patient should be kept in bed, and in the acute attacks all food should be withheld. Thirst may be quenched by small bits of ice kept in the mouth or a few drops of hot water may be given at frequent intervals. If the disease extends over a period of several days, rectal alimentation or the admin- istration of salt solutions must be resorted to. In this condition the diet should chiefly be liquid or semi-solid. All indigestible food should be avoided, DIET IN CHRONIC INTESTINAL OBSTRUCTION. DIET IN INTESTINAL DISEASES. 295 especially those forms that are apt to leave a large amount of residue in the bowel. The foods to be avoided are salads, heavy vegetables, and fruits. Milk broths, eggs, broiled meats, chicken, sweetbreads, boiled fish, rice, farina, toast, crackers, and butter are permis- sible. In advanced cases rectal feeding must be carried out. DIET IN APPENDICITIS. The dietetic treatment in this disease must be governed by the symptoms, for surgical treatment is usually indi- cated. The patient should be put to bed and under no condition be allowed to rise until recovery is complete. During the first days Sahli and Penzoldt recommend that all food be withheld ; liquids, such as egg albumin, weak tea, thin broth, barley or rice water, or milk diluted with lime water, may be given in small quantities when deemed necessary. When the acute symptoms have subsided this diet can be increased somewhat; the milk may be taken undiluted and eggs may be added to the broth. When the pain and fever have disappeared entirely, gruels made of rice or barley, soft-boiled egg, scraped beef, stewed chicken, toast, and crackers may be added to the list; still later mashed potatoes and vegetables- finely divided and strained-may be allowed, and finally, when the patient is well, the usual diet may be resumed. Ochsner advises the following plan of treatment in all cases of appendicitis in which operation is to be per- formed, believing that it reduces the mortality and changes the class of cases in which the mortality is greatest into another class in which the mortality is very small after operation: "In every case of acute appendicitis all food by mouth and all cathartics are prohibited. In case the patient 296 DIETETICS FOR NURSES. suffers from nausea or vomiting, gastric lavage is at once employed. In the milder cases the patient is permitted to rinse the mouth with cold water and to drink small sips of very hot water at short intervals. In the severer cases the patient is permitted to rinse the mouth with cold water, but is not permitted to drink either hot or cold water for the first few days until the acute attack has subsided, when the use of small sips of hot water is begun. If the nausea persists, gastric lavage is repeated once or twice at intervals of two to four hours, in order to remove any substance which had regurgitated into the stomach from the small intestine. " The patient is supported by nutrient enemata, con* sisting of an ounce of one of the concentrated predigested liquid foods in the market, dissolved in 3 oz. of warm normal salt solution, introduced through a catheter which is inserted a distance of 2| to 3 inches. In case this gives rise to pain or irritation or nausea, it is inter- rupted for twelve to twenty-four hours at a time. In cases in which no water is given by mouth, an enema of 8 oz. of normal salt solution is given four to six times a day in addition to the nutrient enemata. In cases operated during the acute attack this treatment is con- tinued for several days after the operation. " After the patient has been free from pain and other- wise practically normal for four days he is first given from 1 to 4 oz. of weak beef tea, preferably prepared from commercial beef extract, every two hours. In a few days one of the commercial predigested foods, dis- solved in water, is substituted; still later, equal parts of milk and lime water; then general liquids, then light diet; and finally, after the patient has fully recovered, full diet is given." DIET IN INTESTINAL DISEASES. 297 DIETETIC TREATMENT OF NERVOUS CONDITIONS OF THE INTESTINE. This condition resembles nervous dyspepsia. At times the most indigestible food is well borne, whereas the digestible forms create discomfort; in each case it is important that the diet be regulated according to the patient's digestive powers. Generally a liberal diet is indicated in these cases; in many instances a systematic rest cure is needed to bring about relief. Flatulence.-This condition is characterized by an excessive accumulation of gas in the intestine. In the dietetic treatment, therefore, foods that tend to produce large quantities of gas, such as beer, cider, carbonated waters, fruit, cabbage, rye and Graham breads, and potatoes, should be avoided. The disorder is often of purely nervous origin, and when this is the case unre- stricted diet is to be recommended-one that will tone up the patient's system and thus cause the flatulence to disappear. DIETETIC TREATMENT FOR HEMORRHOIDS. Since constipation is often a frequent cause and accom- paniment of hemorrhoids, it is important that this condi- tion be corrected. As has been pointed out elsewhere, proper diet plays an important role in the prevention of chronic constipation. Patients afflicted with hemorrhoids should eat in moderation, but should avoid all excesses of food and drink. An abundance of outdoor exercise, consisting of walking and simple gymnastics, should be indulged in; violent gymnastics and horseback-riding should be avoided. A daily evacuation of the bowels should be secured. Patients with hemorrhoids should avoid alcoholic beverages, spiced foods, strong coffee 298 DIETETICS FOR NURSES. and tea, cheese, cabbage, and beans. The foods most suited to this condition are potatoes, carrots, spinach, asparagus, and even salads, since they stimulate intestinal peristalsis and thus help to keep the stools soft. Stewed and raw fruits, including grapes, oranges, pears, and apples, are also beneficial. Water is the best beverage in this condition. The waters of Carlsbad, Kissingen, and Saratoga are most beneficial; they act best when taken at the springs. DIETETIC TREATMENT OF DIARRHEA. The dietetic treatment of diarrhea must vary accord- ing to the type of the disorder. In the nervous variety the patient should be instructed to restrain his bowel movements except at a certain hour in the morning. Under all conditions it is important to exclude from the diet all foods that have a tendency to stimulate the intestines. Coarse, indigestible foods, especially those containing a large percentage of cellulose, must be avoided; in this class are especially to be mentioned cabbage, pickles, salads, turnips, carrots, all cold drinks, carbonated waters, and beverages (including champagne and beer). Among the foods to be recommended are broths, tea, red wines, farina, rice, and barley gruels. Raw milk usually has a laxative effect, but when boiled or diluted with lime water or brandy it is constipating, although in a certain number of cases it must be entirely excluded, as it increases the number of movements. In a number of cases of chronic diarrhea milk cures have been given with good results. The authors have suc- ceeded in relieving cases of chronic diarrhea by sys- tematic rest cure.

In the dietetic treatment of habitual constipation it is essential that the food that is ingested should be such as will increase the intestinal movements. Those foods that leave a large bulk of fecal matter are useful for this purpose. Those that leave a small residue are most apt to produce chronic constipation. A diet consisting principally of eggs and milk with only a small quantity of vegetables and water is one that is constipating. A glassful of cold water taken before breakfast will often regulate the bowels; occasionally, according to Penzoldt, a pinch of salt added to the water will increase its efficacy; raw or cooked fruit, taken on an empty stomach morning or evening, occasionally gives good results. It is a well-known fact that the smoking of a cigar in the morning will often stimulate intestinal move- 300 DIETETICS FOR NURSES. ments. The patient should recognize the importance of having an evacuation of the bowels at the same time each day. Chronic constipation is a frequent accompaniment of dyspeptic disorders, and may be relieved by appropriate treatment of the gastric disorder. It should not be for- gotten that habitual constipation is frequently induced by the persistent use of cathartics, and the use of drugs should be avoided as much as possible in the treatment of this disorder. Sedentary habits are often the cause of constipation, and for this reason proper exercise should always be prescribed along with the dietetic treatment. The vegetables that are especially useful in the treatment of chronic constipation are spinach, peas, cauliflower, cabbage, asparagus, salads, onions, celery, and tomatoes. The cereals that stimulate the intestinal movements are oatmeal and cornmeal. Graham, rye, corn, whole wheat, and bran breads are also useful. Other foods classed as laxatives are honey, cider, molasses, and acid fruits, such as apples, pears, peaches, cherries, and oranges. On account of the acids and seeds they contain, berries are effective laxatives. Prunes, dates, and figs are also to be recommended. Habitual constipation is often due to the fact that water is taken in insufficient quantities; therefore, in the treat- ment of the disorder, an abundance of water must be pre- scribed. The foods to be avoided are tea, claret, cocoa, chocolate, rice, barley, and farina gruels, and huckle- berries. In some cases milk acts as a laxative, whereas in others it has the opposite effect. For this reason its effect should be tested in every case. Boiled milk usually constipates. Buttermilk is preferable to sweet milk as a laxative. Most cases of habitual constipation can be re- lieved or cured by the dietetic treatment here laid down. DIET IN INTESTINAL DISEASES. 301 Boas1 has recently called attention to the fact that in a certain class of cases of chronic constipation, excellent results are obtained by the rest cure. The patient is isolated for fourteen days and is not allowed to leave his bed. The nourishment of the patient is regulated for each day, and for each meal. No effort is made to increase the patient's weight, although great importance is attached to giving food regularly. The treatment is continued for from four to six weeks. It is not within the province of this book to discuss the value of massage and electricity; suffice it to say that they are reliable adjuvants to the treatment of constipation. The authors frequently prescribe the following diet in cases of chronic constipation: Calories. 6 A. M.: 40 gm. orange juice 88 8 A. M.: 300 gm. milk with coffee 192 2 soft-boiled eggs .160 150 gm. Graham bread 375 40 gm. butter 326 IO A. M. ; 400 gm. cider 280 12 M.: 200 gm. broth, with 1 egg 84 100 gm. steak 214 IOO gm. carrots 41 100 gm. beans 193 15° gm.

DIET IN PERITONITIS. Acute Peritonitis.-The diet in acute peritonitis is purely of secondary importance and requires considera- tion only until operative procedure can be undertaken. No food whatever should be given by the mouth; if necessary, rectal alimentation should be resorted to. If operation is not undertaken and vomiting has ceased, fluids may be given in a few days. Foods that may be prescribed are milk and lime water, diluted broths, and egg albumin with or without brandy or sherry; only very small quantities should be taken at a time, but at frequent intervals; gradually plain milk, broth, and gruels may be added to the list; solid food should not be allowed for several weeks. When stimulants are re- quired they should be given in the form of whisky, brandy, or champagne. Chronic Peritonitis.-The diet in chronic peritoni- tis should consist of boiled meats, eggs, milk, stale bread, toast or crackers, and vegetables, only, however, in the form of purees; carbohydrates should be eaten sparingly on account of their tendency to ferment. Food should be eaten in small quantities at regular but frequent intervals. CHAPTER XIII. DIET IN DISEASES OF THE LIVER. Certain general principles of dietetics apply to all dis- eases of the liver. The condition usually called " bilious- ness " is a cry of the liver for relief from overwork. The administration of calomel or a saline laxative followed by a few days of restricted diet is all that is necessary in most cases. In general it may be stated that in diseases of the liver the food should be easily digested and con- sist of a mixture of proteins, carbohydrates, and fats. In many cases it is desirable to limit or even to avoid alto- gether both fats and carbohydrates. Certain articles of diet are known, while others are believed, to be injurious in diseased conditions of the liver. Overeating is injurious ; first, on account of the overwork it necessitates; and secondly, because the superfluous food is apt to undergo putrefaction. The re- sulting bacterial products are believed to act on the liver in much the same manner as does alcohol. The exces- sive use of alcohol produces marked changes in the liver in certain individuals. In all liver diseases alcohol should be avoided unless specially indicated as a tonic or stimulant. In any case it should be given well diluted. Certain foods have been regarded as "stimulating" or "irritating" to the liver. Among these are peppers of various kinds, spices, mustards, concentrated meat ex- 304 DIET IN DISEASES OF THE LIVER. 305 tracts and meat broths, and the substances formed in roasted and baked meats. To be proscribed are peppers, radishes, horseradish, onions, watercress, and celery. Salt in too large quantities is also to be condemned. Strong coffee and tea are harmful, but weak tea seems to be well borne in many cases. In severe diseases of the liver the diet must usually be restricted to milk, diluted or peptonized; gruels, albumin water, kumiss, buttermilk, and bland broths, such as oyster broth. Orange juice as well as lemonade may generally be allowed. In the milder diseases and during convalescence the diet need not be so rigid, and lean meat, curd, junket, bread, toast, zwieback, fresh fruit, or stewed fruit with little or no sugar, may be allowed. In the chronic cases and lighter forms the following articles may help to make up the dietary : Milk, variously diluted and prepared; buttermilk, curd, kumiss, custard, junket, eggs, lean meat-if beef or mutton, preferably rare-sweetbreads, chicken, squab, liver, the soft part of oysters and the more digestible forms of fish. Fresh green vegetables and green salads without oil are permissible. Small quantities of well-baked or boiled mealy potato may be allowed once a day, for many persons do not relish a meal that does not contain potato in some form. The starchy foods should be partaken of somewhat sparingly; bread, toast, zwieback, pulled bread, and biscuits (crackers) may be permitted. Small quantities of cereal foods may be taken; rice, sago, and tapioca, when sufficiently well cooked, may be allowed. Fresh fruit is a valuable adjunct to the diet. Oranges, grape-fruit, ripe peaches or pears, strawberries, ripe plums of the most tender varieties, may all be taken. Stewed fruits only slightly sweetened and baked apples may be allowed with advan- 306 DIETETICS FOR NURSES. tage. If there is constipation, stewed prunes are useful. Lemonade may be taken as a beverage. Mineral waters may be drunk freely if dropsy is not present, and are best taken on rising and between meals. Hot water is a valuable substitute for the mineral waters. It is especially useful in allaying thirst when there is dropsy. The food should be taken slowly, well masticated, and never in too large quantities. If necessary, more milk may be given, so as to make large amounts of other food unnecessary. The patient should lie down directly before and after meals. In no case should the patient eat immediately after taking active exercise. In certain chronic conditions, such as hyperemia, fatty degeneration, and chronic hepatitis, exercise is to be taken at proper times. In summer and in warm climates more vegetables are to be allowed and less meat. If putrefactive changes take place in the intestine, a diet consisting of white of egg and water should be maintained until this condition is overcome. When the putrefaction is caused by tor- pidity of the liver, it may sometimes be prevented by increasing the amount of vegetables and by the use of laxatives. Diet in Gall-stone Disease.-The meals should be taken at regular intervals and not too widely sepa- rated. Prolonged fasting should not be permitted. A substantial breakfast should be taken when not other- wise contra-indicated, and not the simple " continental " breakfast of coffee and a roll. A late supper is of value, and it may be advisable in some instances to give the patient nourishment at night. Fat should be reduced to a minimum or avoided entirely, and the starches and sugars limited in amount. CHAPTER XIV. DIET IN DISEASE OF THE RESPIRATORY ORGANS. Pleurisy.-Two plans of dietetic treatment may be followed. The first is to place the patient on a milk diet. The second is to place the patient on a " dry diet." This consists of the ordinary diet with the fluids limited in amount. No soups, but little tea or coffee, are allowed, and but small amounts of water. The milk diet is preferred where there is fever or complicating heart or kidney disease. Empyema (Pus in the Pleural Cavity).-As nourish- ing a diet as is possible should be used according to the general principles of feeding fever patients. Laryngitis.-In chronic disease of the larynx there may be great pain on swallowing. All hard and highly seasoned foods are to be avoided. Only semi-solid and liquid foods should be given. The physician sometimes prescribes drugs to allay the irritation in the throat at meal time. Difficulty in swallowing may sometimes be overcome by the following two methods : By allowing the patient to lie flat on a lounge with his face over the edge. Food is to be sucked through a tube from a vessel placed im- mediately below. The second method consists in direct- ing the patient to lean forward while eating. Asthma.-Certain forms of asthma may be brought on by errors in diet leading to attacks of indigestion. 307 308 DIETETICS FOR NURSES. Patients suffering from this should partake only of easily digested food and should lead regular lives. The meals should be taken at regular intervals. Dinner should be eaten in the middle of the day and the supper should be light. Late suppers should not be taken, and eating between meals should not be allowed. Diet in Chronic Lung Disease.-In all chronic diseases of the lungs the diet should be as easy of diges- tion and especially a diet which will not cause flatulence, as this pushes up the diaphragm and interferes with breathing. (See Diet in Diseases of the Heart.) Pneumonia.-The diet in pneumonia is of the great- est importance. The patient's recovery often depends upon the matter of his being well nourished. The same general principles of feeding should be fol- lowed as are indicated in all acute fevers. During the course of the disease the patient should receive an abundance of water in addition to the liquid food sup- plied. Plain water or any carbonated water that the patient may desire should be given. Milk and seltzer may be allowed freely. Lemonade or orangeade, or water flavored with tamarinds, may serve to lend variety. The " Imperial drink " (the recipe for which appears at the end of this book) may also be given. During the height of the disease milk should form the basis of the diet. This may be peptonized or diluted with lime water. Albumin water, wine whey, malted milk, beef juice, Eskay's food, and similar preparations may be employed when milk is not well borne. Predi- gested liquid beef preparations may be used both for their stimulating effects and as a food. They should always be diluted freely with water unless, because of vomiting, a concentrated food is indicated. DIET IN DISEASE OF RESPIRATORY ORGANS. 309 Food should be given at regular intervals of from two to four hours, according to the patient's condition and the amount he is able to take at one time. Constipation, flatulence, and vomiting are to be avoided whenever possible. If they do occur, efforts should at once be made to relieve the condition. In most cases starches and sugars are best omitted from the diet. Fruit may be allowed at any time during the disease, and is of special benefit during convales- cence. Most grateful during the severe stage are orange juice, lemonade, grape-fruit, and grapes. During conva- lescence ripe peaches or pears in season may be added to the diet. The return to a general diet should be made gradually, and no solid food should be allowed until the fever has subsided. Then the general dietetic rules for convalescents may be followed. Alcohol is given only according to the directions of the physician. CHAPTER XV. DIET IN DISEASES OF THE CIRCULATORY SYSTEM. DIET IN DISEASES OF THE HEART. General Directions for Diet.-The diet for patients with heart disease usually requires considerable atten- tion. In general there are two stages of heart disease. The first is called " the stage of compensation," when the heart, although diseased, is still able to pump the blood through the body. The second stage, or " stage of broken compensation," is when the heart, no longer able to cope with its work, is unable to force the blood through the vessels as it should and there is a certain amount of damming back of the blood. This causes numerous unpleasant symptoms, such as edema, diffi- culty of breathing, and irritability. During the first stage the diet requires comparatively little attention beyond the observance of certain general rules. When the second stage is approaching the diet should be carefully supervised, for the patient may be spared much suffering, and often the time of the broken compensation postponed. The meals should be small; more should never be given than the patient can easily digest. If the stomach is overloaded the diaphragm is pushed up and displaces the heart, and this may occasion palpitation and dyspnea. If the meals are too large the residue of any digested food in the intestine may undergo fermentation and 310 DIET IN DISEASES OF CIRCULATORY SYSTEM. 311 cause flatulence, with its attendant disagreeable symp' toms. The meals should be simple and well cooked. Im- properly prepared food is a cause of indigestion, and may produce flatulence or discomfort. The food chosen should be of a kind that is easy of digestion. A suffi- ciently long interval should be allowed to elapse between meals, and eating between meals should be strictly pro- hibited, as even small portions of food taken when digestion is in progress may give rise to flatulence in these patients. The meals should all be of equal size ; while the even- ing meal may be a little smaller and lighter than the others, and the principal meal should be taken at midday, there should, as has been said, be but comparatively little difference in their size, and the patient should be instructed carefully in this regard. The amount of fluid taken should not be too large, nor, on the other hand, should it be too small. When compensation has been lost, the question as to the amount of fluid to be taken becomes of much impor- tance. At no time should it be forgotten that fluids dis- tend the vessels, raise arterial tension, and increase the work of the heart. If the quantity of fluids given be too small, elimination is delayed and the irritative effect of the retained impurities in the blood proves harmful. Fluids should be taken between meals and are best sipped slowly. Weak tea and coffee may be allowed in small quantities between meals; if they do not cause flatulence, however, they may be allowed at meal times, but always in great moderation. Alcohol is best avoided. If, owing to the general weakness of the patient, its use is indicated, it should be 312 DIETETICS FOR NURSES. given in small quantities, and in the form of pure whisky or brandy well diluted. Wine and beer are contra- indicated. In general it may be said that a diet of plainly pre- pared food, unencumbered by too many restrictions, is best in these cases. All highly seasoned food and the condiments in gen- eral should be omitted from the diet, as they tend to stimulate the appetite of the patient and may cause him to take more food than is necessary or desirable. Stews and fancy dishes should also be omitted, as should the foods usually classed as difficult of digestion, such as fried foods and the like. Starches, sugars, and fats should, as a rule, be re- duced ; this restriction, however, should be enforced strictly only when made necessary by complicating stomach disorders coming on as compensation rupt- ures, when they are apt to cause fermentation and flatulence. Broadbent dwells on the necessity for giving a diet containing about the usual proportion of food constitu- ents. Starches and vegetables are useful additions to the diet, as they help to keep it from being too largely nitrog- enous. If too much protein material is taken it is imper- fectly oxidized, and the waste accumulating in the blood increases the work of the heart, just as when too much food is taken. The diet should consist largely of milk and of dishes made from this food ; eggs, rare meats, especially mutton and beef; poultry, fish, and oysters. Well-baked bread, rolls, or biscuits, which are never to be eaten warm, and cereals in moderate quantities may be allowed. Well- cooked potatoes, spinach, asparagus tips, cauliflower tops, DIET IN DISEASES OF CIRCULATORY SYSTEM. 313 and other similar vegetables may be taken, all stalks being avoided. The diet list should be simple and such as will not require complicated directions. As compensation becomes impaired, numerous disor- ders of digestion occur and require care and attention. The patient with heart disease may develop a distaste for food, and this will often tax the ingenuity of the physician. As blood-stasis sets in, constipation is apt to occur. Hypostatic congestion of the liver comes on, causing lessened metabolism, and consequently interfering greatly with the general nutrition. The stomach and intestine are affected and a chronic catarrhal condition of both is generally present. The quantity of fluid given should now be regulated carefully, neither too much nor too little being given. A glassful of Vichy half an hour before eating will help to prepare the stomach for a meal, and will, as a rule, be excreted promptly. Fluid is absolutely necessary for metabolic changes, and may be taken in the form of the " Imperial drink," elsewhere described, between meals. A glassful of hot water flushes out the body, and as it is rapidly excreted does not add materially to the amount of fluid present. In the Oertel treatment of heart disease the fluids are allowed only in a very limited degree. If the patient is on a milk diet, other fluids besides milk should be given in comparatively small quantities. If edema is severe the food may be given in as concen- trated a form as possible. If flatulence is troublesome, fats, starches, and sugars, as well as beer, pastry, and stews, are to be avoided. No solid food should be taken between meals. Coffee or tea 314 DIETETICS FOR NURSES. taken with the meals may give rise to flatulence. They may, however, in some cases be taken during the day, at a time when the stomach is empty; they should be freshly prepared and should never be strong. Only such quantities of food as the patient can digest should be allowed, and if necessary digestion may be aided by giving essence of pepsin or other digestives. In some cases a milk diet may become necessary. Sudden dilatation of the heart occurring during or fol- lowing any acute disease requires rest and a milk diet. Palpitation and dyspnea are often caused by the inges- tion of too abundant meals; if persistent the food should be given in smaller quantities and at shorter intervals. Four or five small instead of three large meals may be taken at regular intervals, or a milk diet may be ordered for a time. The general management may be such as has been suggested for flatulence. Tea, coffee, and tobacco should be avoided, and effervescing drinks may also be omitted. If there is constipation, stew'ed fruits, especially prunes or figs, are useful. Gastric disturbances are best met by rest and a milk diet for a time, with a gradual return to the ordinary diet or a diet such as is advised for cases of gastric catarrh. Much relief frequently follows the drinking of a glassful of hot water or of Vichy half an hour before a meal. As ruptured compensation is accompanied by effusion, something must be said with special reference to the re- moval of fluids from the body. Here, indeed, feeding is a difficult task, for the patient usually has a disgust for food. If the patient is very ill, nourishment may be administered every three hours. If he is able to be about, it will often be well to allow him to take his meals with the family at the regular meal time. He may be given DIET IN DISEASES OF CIRCULATORY SYSTEM. 315 chicken, tender meats, fish, oysters, and other forms of light food. When but little is taken at the regular meal time, food may be given between the meals at regular periods, time being allowed for. complete digestion to take place. Milk, albumin water, egg and milk, soup, or beef tea in small quantities are useful for this purpose. Broadbent recommends meat or chicken jelly or meat extracts for their stimulating effect on the heart. Potted- meat sandwiches or meat pulp, prepared as directed for tuberculosis patients, may be given. Fluids other than milk and soups should be taken in as small quantities as possible. " Imperial drink " or hot water, as previously suggested, may be given to quench the thirst. Stimulants are usually needed, but should be given only under the supervision of the physician, as there is a tendency to take too much to relieve faintness or other symptoms. In non-alcoholics, from | to 2 oz. of whisky a day may be allowed at the beginning, the amount being increased as occasion demands. Stimulating drugs have largely superseded the use of alcohol in these cases. Aneurism; Dilatation of the Blood-vessels.- Special diets are sometimes prescribed for these patients. Tuffnel's diet, which restricts the foods to a very small quantity and enforces absolute rest, is the best known. Whether or not such diets should be used is a matter to be decided only by the most expert knowledge. Angina Pectoris.-Small easily digested meals are to be given according to the general rules for dieting heart disease. Anemia.-There are a number of different kinds of anemia, and the diet depends somewhat upon the form present. That following the loss of blood is usually 316 DIETETICS FOR NURSES. rapidly recovered from. In this form infusions of salt solution are sometimes given. In general it may be stated that anemic persons require fresh air and sunshine and good food. Fresh food, milk, eggs, meats, green vegetables, and fresh fruits are the most important articles of diet. The meals should be given at regular intervals and not too widely separated, usually about three hours apart. The meals should be small. Eating between meals should be absolutely pro- hibited, and this may require some watching, as the patient frequently has a very capricious appetite, eating all sorts of indigestible articles between meals and leaving the regular food untouched. The breakfast should be a good, nutritious one and consist of meat or eggs in addi- tion to other articles of food. Milk is valuable, but should not be given to the exclusion of other food. It is a good plan to have it taken toward the close of the meal, as otherwise the patient may spoil his appetite by drinking a glassful of milk at the beginning of the meal. Rest before and after meals is desirable. High. Blood-pressure.-In this condition diets low in nitrogen are usually prescribed. If the heart is in good shape, increased amounts of water are usually given to aid elimination. CHAPTER XVI. DIET IN DISEASES OF THE GENITO-URINARY SYSTEM. Urine and Food.-The urine bears a direct relation to the quality and quantity of food ingested, as well as to the quantity of fluid taken and the amount of work done by the individual. Many variations occur in the urine that are due to food or drink and that are normal. When the kidneys are diseased improper food may bring on dangerous or even fatal complications. One of the first principles of dieting persons with dis- eases of the kidneys is to avoid giving them food which is irritating to the kidneys. Among these may be men- tioned the browned outer surfaces of grills and roasts, strong sauces, spices, pastry, very acid foods, strong alcoholic drinks, and strong tea and coffee. Green vege- tables are to be avoided in acute diseases of the kidneys, as well as cranberries and fruits which contain kernels. As regards meats in the acute conditions, they are to be avoided until ordered by the physician. There is a popu- lar idea that the light meats are less injurious than the dark ones; this has no foundation. Glands, such as liver, sweetbreads, kidneys, and spleen, should be avoided. Strong meat broths are also injurious. Alcohol is to be avoided in all cases except when prescribed by the attending physician. All alcoholic beverages are irritating to the diseased kidneys, and if 317 318 DIETETICS FOR NURSES. anything they are more injurious in the chronic cases than in the acute. Water may be given freely in all cases where the urine is increased with the increase in the amount of water taken. It aids in the elimination of waste products. When, however, the amount of urine is greatly dimin- ished or none at all is passed, the physician should regu- late the amount of fluid that is given the patient, as there may be danger in giving too much. Acute Inflammation of the Kidney; Nephritis. -During the first stage of the acute condition in the severer cases food is given in very small quantities, a pint of milk a day. To relieve the thirst, tablespoonful doses of water may be given or pieces of ice may be placed in the mouth. In this stage the physician frequently pre- scribes some form of alcoholic stimulant. In the less severe cases a strict milk diet is followed, or, what is generally preferred, IJ quarts of milk is given with about | pint of cream. Rice, groats, cornmeal por- ridge, crackers, and zwieback may be added if the patient has any appetite, and butter, sugar, and grape juice or other fruit juices may be given. Plain or carbonated waters, the " Imperial drink," weak lemonade, buttermilk, and similar drinks may be given. As convalescence advances calves'-foot jelly and similar preparations are allowable. Light vegetables may be added to the diet; spinach is perhaps the best, but cauliflower tops, young peas, or young string-beans may be used. In acute cases and their convalescence the patient's appe- tite is a fairly good guide as to the amount of food to be taken. Meat and eggs are to be added to the dietary last of all. For a long time after an attack of inflammation DIE T IN DISEASES OF GENITO- URINAR Y S YSTEM. 319 of the kidneys the patient should avoid the articles of food which are irritating to the kidneys. Chronic Inflammation of the Kidneys.-In this disease the diet should be very much like that suggested for old people. (See Diet for the Aged.) Alcohol is to be avoided, as are tea and coffee and all the foods set down as irritating to the kidneys. The amount of fluid taken should not be excessive. There is a popular idea that in this disease the more fluid one takes the better; this is not true, and in some cases excessive amounts of fluids are distinctly injurious. An occasional drinking- day or drinking-week is sometimes allowed, during which the patient drinks large quantities of water to flush out the system. This is frequently accomplished by an occa- sional visit to a watering-place, where the change of scene is often of as much value as the waters. Exercise, fresh air, freedom from care and worry, suitable occu- pation, and pleasant surroundings are all important. A change of air to a dry, warm climate is often of great benefit. The trend of modern medicine is to study the metabo- lism of the patient with chronic nephritis and to allow a diet which is suited to the case in hand. In former days many ill-advised and drastic changes in diet and manner of life were advised, often without much real benefit. The test-diet used in nephritis cases varies somewhat. The actual amount of food eaten should be noted and the amounts of protein and nitrogen and salt can be deter- mined and the physician forms his judgment from a study of the urine excreted by the patient while on the diet. The following shows a list used in Janeway's Clinic at the Johns Hopkins Hospital: 320 DIETETICS FOR NURSES. For Date All food is to be salt-free food from the diet kitchen. Salt for each meal will be furnished in weighed amounts. All food or fluid not taken must be weighed or measured after meals and charted in the spaces below.

It consists of 800 c.c. milk given in twenty-four hours as the only food or liquid allowed. This is a fifty-year-old diet suggested by a famous Russian physician. Another point to remember is that many drugs are in- jurious to the kidneys, and the taking of indiscriminate headache powders and other things without a knowledge of what they do or of what they contain is a habit which, if for no other reason than protecting the kidneys, is to be most highly condemned. Movable and Floating Kidney.-This trouble is sometimes seen after rapid loss of flesh from any cause. A rest or careful feeding to regain the original weight is in many cases of great service. Calculous Affections.-The tendency to stone for- mation, as in the kidney or bladder, and the much-talked- of condition usually called the uric acid diathesis, may be considered together. In many instances, but by no means all, too rich food, too large meals, and too little exercise are at the bottom of the trouble. The following suggestions regarding the diet will be found useful: Avoid strong drinks, and all alcohol if possible ; much meat, and especially the nuclein-contain- ing meats, as thymus, spleen, liver, brain, caviare, etc., smoked, pickled and spiced meats, and rich foods in general. The fats and sugars as well as the cereals should be restricted. The diet should be made up of the plainer, well-prepared foods, and so far as possible a vegetable diet should be prescribed. Water, especially the alkaline mineral waters, may be allowed in abun- dance. A sojourn at Carlsbad may be recommended for certain obese patients. 324 DIETETICS FOR NURSES. Mineral waters must be used with extreme caution, for if too much alkaline water be taken it may increase the deposit of certain earthy salts. The physician should direct the kind and amount of such waters as are to be taken. SURGICAL DISEASES OF THE GENITO- URINARY TRACT. The directions for diet are very simple. All irritating foods and drinks should be avoided, as should all indi- gestible articles. The diet should consist of plain and wholesome food. Where it is possible, skim-milk should form the basis of the diet. Too much meat should not be taken, and twice-cooked meats and fried and very greasy foods avoided so far as possible. Carbohydrates, as breadstuffs, cereals, and the non-acid vegetables, may be allowed. Care should be taken to avoid all com- plicated and highly seasoned foods, all pepper, spices, and salad dressing. In a word, everything previously mentioned as irritating to the genito-urinary tract should be avoided. Acid fruits, asparagus, and tomatoes are also to be forbidden. Tea and coffee should be pro- hibited or given very weak and well diluted with milk or cream. All alcoholic drinks should be forbidden. CHAPTER XVII. DIET IN DISEASES OF THE NERVOUS SYSTEM, The necessity for the correct management of the diet in nervous diseases is becoming appreciated more and more every year. As a general rule, it may be stated that all functional diseases attended with emaciation are greatly benefited, if not entirely relieved, by merely in- creasing the patient's weight by such methods as are suggested under the heading of Rest Cure. Patients with chronic lesions will, as a rule, be made more com- fortable if the following two points are borne in mind: First, to overcome, so far as possible, emaciation and anemia where the nutrition has a tendency to be below normal; and secondly, and of no less importance, to prevent undue obesity in those so inclined, particularly where there is disturbance of locomotion. A patient may be condemned to remain in bed or in a chair on account of the excessive weight which his inactivity has fostered. Most patients regard diet as a very unimportant part of the treatment; this is especially true of those cases that most need careful feeding. The necessity for careful dietary should be impressed upon these patients, and a faith in its efficacy engendered where the disease is of a functional nature. The diet suitable in nervous diseases has been the 325 326 DIETETICS FOR NURSES. subject of many diverse opinions, particularly in the minds of the laity. Fish has been vaunted as a " brain food," and various fats or cereals have been suggested for nervous conditions. At the present time, it may be stated, there is no specific " nerve food." The nutrition of the nervous system will be good when the patient's general nutrition is good, and vice versa. Both in func- tional disorders of the nervous system and in the psy- choses dependent upon exhaustion the improvement of the general condition should be the first care. The basis of the diet is usually milk. Care should be taken to see that the patient gets sufficient fluid, and where no tendency to obesity exists water should be taken with each meal, and usually at bedtime and on rising. It may also be taken between meals if desired. When there is disturbance of digestion, it is a good plan to prepare the stomach for the meal by sipping a glassful of hot water on rising and an hour or less before each meal. The mineral waters may be used when desired; the alkaline ones are apt to be of most value. Carbon- ated waters should be used with care, lest the flatulence they may cause give rise to symptoms the importance of which may be greatly exaggerated by the patient. A question of great importance is whether or not alcohol should be used. As a general rule, it should not be allowed. In cases with chronic lesions, where the patient has been accustomed to the use of alcohol all his life, it may be allowed if not otherwise contra-indicated, as in a tendency to cerebral hemorrhage, arteriosclerosis, chronic interstitial nephritis, and the like. The use of alcohol in the functional disorders is usually contra- indicated. Its value as a food and as a stimulant to nutrition should not be overlooked, and it may be used DIET IN DISEASES OF THE NERVOUS SYSTEM. 327 with great benefit in the psychoses accompanied by ex- haustive conditions. NEURALGIA. Some cases of neuralgia are directly caused by indis- cretions in diet; other cases depend on a lowered state of nutrition, while still others may be due to plethoric states. Neuralgia is also caused by many factors not related to the diet of the patient. To decide this ques- tion requires great experience and judgment on the part of a skilled physician. As a general rule, plain, wholesome food should be ordered at regular intervals. The patient should not be allowed to eat between meals. All rich, complex, and highly seasoned foods should be forbidden, as should all fried foods, pastry, and anything known to disagree with the patient. Care should, however, be taken that the diet be not restricted, for the patient's ability to take dif- ferent articles is often purely imaginary. True idiosyn- crasies for different articles of food are not very common. The excessive use of tobacco may be the cause of neuralgia. INSOMNIA AND DISTURBED SLEEP. When not dependent upon other conditions, these are apt to be due either to eating at night or to a depressed state of the nutrition. For the first there is nothing to do but to discontinue the habit of eating at night. There are but few persons who reach middle age and can eat late at night with impunity, and sooner or later the individual learns that he must give up the habit. There are some, however, with whom the practice seems to agree. 328 DIETETICS FOR NURSES. When the trouble is caused by malnutrition or anemia, the general condition of the patient must be treated. Good food, regular hours, milk or some light food be- tween meals, and on going to bed a cupful of hot milk, cocoa, or, if preferred, beef tea, malted milk or similar preparation may be ordered. In many cases where the nutrition is fairly good one of the hot drinks just mentioned taken at bedtime may be all that is necessary. This is especially true of the insomnia and disturbed sleep that follow the doing of mental work at night. The effect is to dilate the abdom- inal vessels and to restore the equilibrium of the circu- lation. A brisk walk in the open air or five minutes' exercise will often accomplish similar results. EPILEPSY. Epilepsy bears an important relation to diet. There is no specific " anti-epilepsy " diet, and there is no form of food that can be assigned as a cause of epilepsy; it is, however, a fact that where the diet is carefully regulated, the number of attacks are usually lessened. This is par- ticularly true of children. The principle involved is to give only as much food as the patient can easily digest and assimilate, and to allow sufficient time to elapse between feedings for him to utilize and excrete the end- products of what he does assimilate. When this is not done, attacks may be provoked by irritating substances in the bowel, by the absorption of toxic substances from the intestinal tract, or by the accumulation of the products of metabolism in the body. In the epileptic colonies no especial diet is used, but the amount and the variety of food are so regulated as to secure the best results. DIET IN DISEASES OF THE NERVOUS SYSTEM. 329 In children a diet composed largely of milk, with the addition of cereals and fruit, is most useful. In older persons this diet is not feasible except occasionally as a temporary measure. For these latter meat should be allowed only once a day, unless on account of excessive manual labor or because of a weakened condition of nutri- tion the patient especially demands it. Milk, cereals, bread, vegetables, and fruit should make up the rest of the dietary. Each patient should be instructed to take only digestible food, to take his meals regularly, and not to eat too much. They should also be taught to eat slowly and masticate the food well. The avoidance of constipation is of primary importance, and this can usually be secured by the proper use of fruits and the coarser forms of cereals. Quiet, open-air life, pleasant occupation of a non- strenuous kind, an absence of worry, and agreeable forms of recreation are just as important as the diet in these cases. CHOREA. In chorea the diet is often of the greatest importance; this is especially true when it occurs in anemic or debili- tated children. Rest and an easily assimilable diet are the indications. The authors are of the opinion that absolute rest in bed, if possible isolated from the remain- der of the family and under the care of a trained nurse, who should be a stranger, combined with a milk diet or a diet composed largely of milk, will give better and more lasting results than any other form of treatment. If the patient is anemic, beef juice made from fresh beef may be used to advantage, as well as raw scraped beef and simi- lar foods. 330 DIETETICS FOR NURSES. APOPLEXY. Comatose stage.-During the early stage of the comatose condition-i. e., for the first day or two-there is, as a rule, no necessity for giving the patient any food. As the disease is most likely to occur in obese, overfed individuals, the abstinence from food is often beneficial. The intestinal tract should be flushed out as soon after the patient is seen as is practicable. Those about the patient should be instructed carefully as to the dangers of attempting to feed the patient if he is unable to swal- low, for he may, on the one hand, choke, and, on the other, he may draw food or drink into his lungs during inspiration, and so set up a pneumonia. If the patient is in need of nourishment or of fluid, it may be given by the rectum. Normal salt solution may be given by the rectum to supply the body with fluid, but it should not be given in too large quantities. (See Rec- tal Feeding.) I^ater stages.-As soon as the patient recovers suffi- ciently to be able to swallow without danger of inspir- ing the food he may be fed by the mouth. The food should be liquid or semi-solid, and of a bland, unstim- ulating character. The quantity should not be too large. Milk, milk and eggs beaten together in the form of a milk punch, without, however, the addition of a stimu- lant ; broths, soft eggs, and milk thickened with cereals, or the purees of vegetables may be used. As the patient improves other food may be added, but the diet should be light, easily digestible, and as non-stimulating as pos- sible. The patient should be warned against overeating and also against drinking. Alcohol is allowable only in the case of habitues who are threatened with collapse DIET IN DISEASES OF THE NERVOUS SYSTEM. 331 unless it is used, or in the same class where food is not assimilated without it. It should always be given in moderate amounts, and the dosage arranged by the phy- sician, and never left to the nurse, the patient or the family. On account of the lack of exercise the diet should contain but little meat, but cereals, vegetables, and fruit should be given in small quantities at a time, and as evenly distributed throughout the day as possible, to avoid overfilling of the vessels. The greatest danger, from a dietary standpoint, is in those patients who recover sufficiently to return to their ordinary modes of living. They should be very care- fully instructed neither to drink to excess nor to overeat. A full meal and several drinks may be the cause of a second or of a fatal attack. ALCOHOLISM. The mild forms of alcoholism are usually easily man- aged. So long as the stomach is irritable it should be given absolute rest. If possible, alcohol should be with- held entirely. As soon as the stomach will retain fluid a saline mineral water or a saline purge should be given. Milk or bouillon is next to be prescribed, and as the desire for food returns a light diet of soft-boiled eggs, milk toast and the like should be allowed. After re- covery all rich and highly seasoned food should be avoided, particularly the spices and peppers, which are commonly used to excess. In the severe forms the diet should be that recom- mended for chronic gastritis. Some confirmed alcoholics can retain nothing in the stomach until they have had their morning drink. When nutrition is threatened this may 332 DIETETICS FOR NURSES. be allowed, but it is apt to lead to excesses later in the day. In the very severe forms, as in delirium tremens or in cases approaching it, the patient should take as much fluid as possible to flush out the system, and the intestinal tract should be thoroughly purged. The food should be given in a predigested or in a partially predi- gested form and at frequent intervals. In this way the craving for drink is somewhat alleviated. Bouillon or beef tea to which considerable amounts of black pepper or even Cayenne pepper have been added is useful in this condition, although their use would be contra-indicated for any but an alcohol-saturated person. Rest and sur- alimentation as soon as food can be borne constitute the best method of managing these cases. Strychnin may be used as a stimulant. Illness or Injury in Alcoholics.-When a man who has been accustomed to taking several glasses of spirits every day for years is suddenly stricken ill or injured, delirium will often develop if the stimulant is rapidly withdrawn. In all such cases the accustomed amount of alcohol should be given, care being taken, however, to prevent overindulgence. In alcoholics affected with pneumonia alcohol is neces- sary to sustain life. When delirium occurs in the course of pneumonia alcohol should be ordered, although in ordinary, uncomplicated cases of delirium tremens due to extreme overindulgence it should be withheld. REST CURE. The technic of the treatment is explained in a most interesting way by Mitchell, in his book " Fat and Blood." DIET IN DISEASES OF THE NERVOUS SYSTEM. 333 The more nearly perfect the technic and the more closely it is adhered to, the more likely is cure to follow. The cases are of various grades of severity, and the treat- ment is modified to suit the individual. Isolation is necessary, and the patient should be removed to a hos- pital or a sanitarium, away from familiar scenes. Home treatment does not succeed well. If circumstances com- pel the patient to remain at home, her room should be changed. In severe cases with emotional manifestations visiting is forbidden, but it may be allowed to a " certain extent when the patient is anemic owing to a distinct cause, as overwork, blood-losses, dyspepsia, low fevers, or nursing." The nurse should be a stranger to the patient. Communication with friends and family should, as a rule, be cut off entirely, and not even the reading of letters should be allowed. After several weeks, if the patient is improving, she may be allowed to read the newspaper each day. Rest is a most important feature, and, as a rule, the patient should be put to bed for six weeks or two months. In other cases, especially where the patient is not able to undergo regular treatment, as in dispensary cases, a modified rest cure may be tried. The following is Mitchell's schedule for such cases; this may be modified according to circumstances: " 7.30 a. m. : Cocoa, coffee, hot milk, beef extract, or hot water. Bath (temperature stated). Rough rub with towel or flesh-brush. Bathing and rubbing may be done by attendant. Lie down a few minutes after finishing. " 8.30 a. m. : Breakfast in bed. (Detail as to diet. Tonic, aperient, malt extract as ordered.) May read letters, papers, etc., if eyes are good. 334 DIETETICS FOR NURSES. " I o to 11 A. m. : Massage, if required, is usually ordered one hour after breakfast, or Swedish movements are given at that time. An hour's rest follows massage. Less rest is needed after the movements. (Milk or broth after massage.) " 12 M.: Rise and dress slowly. If the gymnastics or massage are not ordered, may rise earlier. May see visitors, attend to household affairs, or walk out. " 1.30 p. m. : Luncheon. (Malt, tonic, etc., as ordered.) In invalids this should be the chief meal of the day. Rest, lying down, not in bed, for an hour after. " 3 p. m. : Drive (use street cars or walk) one to two and one-half hours. (Milk or soup on return.) " 7 p. m. : Supper. (Malt, tonic, etc., as ordered; detail of diet.) " IO P.M.: Hot milk or other food at bedtime." In extreme cases the patient is made to rest absolutely. No exertion of any kind is to be allowed. The bed-pan is to be used with the patient in the recumbent position. She should be removed to a couch for an hour, both morning and evening, while the bed is being freshened. The patient should be fed, and later, when allowed to feed herself, the meat should be cut up for her. A sponge- bath should be given daily, but if it causes depression it may be given less frequently. After two weeks, if the physician thinks it desirable, the patient may be read to for one to three hours. The monotony of the treatment is not so trying as would be imagined, for the routine of the day occupies most of the time. The nurse and mas- seuse should not talk about or listen to the patient's ills, and the latter should be taught that she must speak of them only to the physician. Massage and electricity are resorted to in order t<? DIET IN DISEASES OF THE NERVOUS SYSTEM. 335 maintain nutrition and circulation while at rest. Mitchell gives minute instructions regarding both. General mas- sage of the whole body is to be given, care being taken not to excite pain by manipulating tender areas. The tapping movements, slapping, and the like are not to be used in nervous patients. Care should be exercised to avoid producing sexual excitement; this may be aroused in both sane and insane patients from friction near the genitals or over the back or buttocks. If it does occur, the operator should avoid the sensitive areas. In the average case massage should be given for an hour daily for about six weeks, and then on each alternate day. The time chosen for this should be about midway be- tween meals. Care should be taken to keep the parts warmed by the massage well covered. The same precautions should be taken in using elec- tricity as when giving massage. The induced current should be used, and it is well to employ a battery in which the breaks are very slow-from two to five seconds. The more rapid interruptions are useful, how- ever, but in the hands of an unskilled operator may excite pain and apprehension in the patient. The poles may be placed 4 or 5 in. apart on the muscle, and the whole body should be gone over. In thin, anemic, exhausted women, who are the ones usually treated, the diet is as follows : The patient is put to bed and the diet generally changed from the ordinary to a milk diet. This is done by giving from 3 to 4 oz. of milk every two hours, after the Karell method. Then the patient is given 2 quarts of milk in each twenty-four hours. The amount is divided and a portion given at three-hour intervals. At the end of the first week a pound of beef is administered in the form of a raw soup. 336 DIETETICS FOR NURSES. This is given three times a day, a pound of beef being used each day. If desired, this may be replaced by pep- tonized food. (See formulas in the Appendix.) After ten days three meals a day are given. These are led up to gradually, and the patient is kept on the milk diet until the stomach feels comfortable. Then, usually within from four days to a week, a light breakfast is allowed, and in a few days more a chop is given at the midday meal. After a short time the patient is given three full meals, together with 3 or 4 pints of milk instead of water, either with or after the meals. After about ten days of this treatment, from 2 to 4 oz. of good fluid extract of malt are given before each meal. " As to meals, I leave them to the patient's caprice, unless this is too unreasonable; but I like to give butter largely, and have little trouble in having this most whole- some of fats taken in large amounts. A cup of cocoa or of coffee and milk on waking in the morning is a good prescription for the fatigue of the toilet." In some of the difficult cases J oz. of cod-liver oil is given half an hour after each meal. If it causes nausea or interferes with the appetite, it is given as a rectal injection. This is of particular service where the bowels are sluggish. It may also be given in the form of an emulsion with pancreas extract. In some it acts admira- bly; in others it may cause tenesmus. SCHEDULE FOR A COMPLETE REST CURE. Until otherwise ordered, absolute rest in bed. No visitors, no reading, and no conversation with nurse on the subject of disease or treatment. First Day.-One quart of milk in divided doses every two hours. 8 a. m. : Cold bath followed by a brisk rub.

Tenth Day.-Cocoa on awakening. 7.30 a. m. : Bath and brisk rub. 8.30 a. m.: Breakfast, including cereal, chop or eggs, bread and butter, and 2 glassfuls of milk with the whites of 2 eggs. 10 to 11 A. m. : Massage. 11.30 a. m. : Half-pint of milk, whites of 1 or 2 eggs. 2 p. m. : Full dinner, including 2 glassfuls of milk and whites of 2 eggs. 3.30 to 4 p. m.: Electricity. 5 p. m.: Glassful of milk with whites of 2 eggs. 7.30 p. m.: Supper including milk and eggs. 9.30 p.m.: Brisk rub and a glassful of milk. Schedule as above until desired effect is obtained. This to be modified to suit the individual case. On twelfth day 2 ounces of malt extract with a teaspoonful of solution of peptonate of iron and manganese is usu- ally ordered. Bowels to be kept open. Use butter in as large quantities as possible. 338 DIETETICS FOR NURSES. The patient is allowed to undertake movements for herself very gradually, being allowed to move about in bed by herself and then sit up, and later on to sit out- doors and then to walk a few steps, to take a drive, etc. If this is not done gradually the moving about may be attended by dizziness, vertigo, or unpleasant exhaustion, which may be avoided entirely by gradually increasing the patient's efforts for herself. DIET FOR THE INSANE. Feeding constitutes a very important part of the treat- ment of the insane. All insane persons who are below the standard of nutrition should be built up and an earn- est effort made to increase the weight of the patient. One of the English alienists was wont to talk of the " gospel of fatness." This is best accomplished by a system of feed- ing somewhat similar to that outlined in the rest treat- ment, the rest being prescribed or omitted as the case demands. It should always be remembered that an in- sane person may contract other diseases besides his mental disorder; this is true especially of stomach and intestinal disorders, which may give rise to delusions regarding the taking of food. When the patient refuses food, the question as to the advisability of feeding him by force arises. Everything considered, it is well to begin the forced feeding early, before the patient has time to suffer from his fasting. It should be accomplished by means of the stomach tube or the nasal tube, and about a liter (i quart) of food should be introduced. The food may be given thus twice daily, and in the case of weak patients three or four times a day. Milk, milk and eggs, and broths may be used for this purpose. A sufficient number of attend- DIET IN DISEASES OF THE NERVOUS SYSTEM. 339 ants should be at hand to control the patient if he be- comes unruly and resists feeding. After a patient has been fed with the tube several times he will often prefer to take his nourishment in the usual manner. Whether the esophageal or the nasal tube is to be used will depend on the preference of the physician. Each has its advantages. The nasal tube is generally pre- ferred, since it is easier to introduce, can not be bitten by the patient, and does not cause the patient to struggle as much as the stomach tube; it may, however, be passed into the larynx, and in this way liquid might be intro- duced into the trachea. This danger is more fancied than real, and can be avoided if the patient is allowed to breathe before the fluid is poured into the tube. While he is breathing the tube should be pinched, and if it is in the larynx this fact will be noticed at once. Ordinarily, but not always, coughing ensues; it does not follow when the pharynx is anesthetic, as it occasionally is in the insane or hysteric. The stomach tube does not allow the food to be regurgitated so easily as the nasal tube, but for this method of feeding a mouth-gag is required, which may injure the mouth or teeth, or it may slip, permitting the patient to bite the tube. If the patient has acquired the knack of regurgitating the food, this may be pre- vented by tickling the ribs while the fluid is being intro- duced. This prevents the fixing of the diaphragm, and is successful in most cases. Tact and experience in handling the insane are of the greatest value. Some nurses or attendants have little difficulty in getting patients to eat, whereas others seem never to learn how to manage them. It must be remem- bered than an insane patient may not eat for reasons that are often easily overcome. He may prefer to take his 340 DIETETICS FOR NURSES. food alone, because he does not think himself worthy of eating at the same table with other people. He may fear that his food has been poisoned, and he should be con- vinced of the fallacy of this by the nurse, who should eat a portion before him or allow him to see the food pre- pared, or he may be given food that can not easily be poisoned, such as eggs, whole vegetables, and fruit. When the patient's confidence is gained the battle is gen- erally won. In some cases the delusion persists for a long time and can not be dispelled. Food should always be served daintily. An insane person who may be very much unbalanced may still no- tice the slightest variations in the way of serving food. Attendants are apt to be negligent in this respect. For all patients who have a suicidal tendency the food should be served on dishes that can not be broken. No knives should be allowed, and the food should be served so as to require no cutting. An attendant should watch those who are apt to bolt their food and see that it is cut into small pieces before serving it. Cases of sudden death have followed the drawing of a piece of meat into the larynx while eating too rapidly. CHAPTER XVIII DISEASES IN WHICH DIET IS A PRIMARY FACTOR. DIABETES MELLITUS. In this disease diet is of primary importance and is, in fact, the principal part of the treatment. None but a skilled physician should ever attempt to regulate the feeding of a diabetic patient, since the well being and frequently even life itself are directly dependent upon the diet. The severity of the disease may be greatly lessened by intelligent and conscientious attention to feeding; in poorly managed cases the outlook is often extremely gloomy. Many complications, causing great suffering on the part of the patient, are the direct result of errors in diet. The nurse in attendance on a diabetic patient should understand the principles of the diet to be followed. Diabetes is a disease in which the capacity to use sugar as food is lessened. A certain definite amount of sugar can be utilized; when the patient exceeds this amount the sugar taken in is passed off from the body in the urine. Not every person who has sugar in the urine is a true diabetic. The sugar which is passed in the urine has not been used as food, and the necessary amount of food must be supplied the patient or there will be a loss of weight. This loss of weight is due to the fact that the patient's own tissues are being burned to supply the necessary 341 342 DIETETICS FOR NURSES. energy for the life processes. When this occurs a com- plication known as acidosis sets in very early. This is a condition in which by-products of the destruction of tissue or of food materials, particularly fats, produce substances which act chemically as acids; these acids must be neutralized in order to preserve a neutral re- action in the blood and body tissues and so withdraw valuable alkalies from the body. It is due to this with- drawal of alkalies that the most serious complications, most typically coma and early death, result. Thus, the general principle to be followed is to keep the patient within such a limit of carbohydrate intake that sugar shall not appear in the urine, and at the same time to supply sufficient food to take care of the body needs. The nurse should bear in mind several things when she is dealing with diabetes. First, is the importance of very strict early treatment. She should supplement the efforts of the physician to secure the complete co- operation of the patient. The success of modern treat- ment of diabetes is entirely dependent on the strictness with which the dietetic and other regulations are ob- served, especially in the early stages of the disease, and the loss of the ability to use sugar may be arrested or lessened by avoiding any strain on the patient's carbo- hydrate tolerance. If the patient is under the care of a physician who understands the study of metabolism the nurse's notes will be of primary importance. These should include a record of the foods taken and actually consumed at the several meals, and should be so kept that the nurse can figure out the food values of what has been taken, so that the physician can see the exact amounts of fat, carbohydrate, and protein that have been consumed, and can figure out the total caloric value of DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 343 the foods, and from the protein the approximate amount of nitrogen ingested. The notes should also include frequent determinations of the patient's weight. The amount of urine passed should be recorded; the total amount for each twenty-four hours should be collected and at least 4 ounces of the mixed specimen pre- served for analysis. Apart from hospitals it is cus- tomary to add some preservative so that the urine will not spoil, and for this purpose a few drops of chloroform are recommended. This chloroform is driven out of the urine before testing by heating. The urine is measured by starting at 7 o'clock in the morning and saving all the urine passed until the following morning. The loss of urine passed during stool may be avoided if the patient is carefully instructed on this point. Many physicians prefer to have the nurse test the urine for sugar and for acid bodies, periodically himself checking these tests. The technic of these tests is easily learned and adds greatly to the nurse's professional equipment. Foods served the patient are weighed before, and the amount not consumed weighed after the meal; thus the exact amount ingested can be determined. It is desir- able that the patient learn the details of management of diet. Certain patients can learn to judge the weight of foods by looking at them, thus enabling them to eat at table with other persons without attracting any attention to their condition. In severe cases and those wherein diet is particularly limited this often proves to be a dangerous experiment. For the exact composition of foods the nurse should have at hand a table giving this information. The tables of W. O. Atwater and A. P. Bryant, published as Bulletin No. 28 of the Experi- ment Stations of the Department of Agriculture of the United States, remains the best source for this informa- DIETETICS FOR NURSES. 344 tion and may be obtained from the government at a nominal cost. These tables as well as others will be found in our larger book, "Diet in Health and Disease." The general hygiene of the patient must be pains- takingly watched, food should be very well chewed, the teeth kept carefully cleansed, and particular care should be taken to keep the skin clean and to avoid any injuries that would draw blood. Infections are par- ticularly prone to occur in these patients and should immediately receive the attention of the physician. The bowels should move twice a day and under no circumstances should the patient be allowed to become constipated. Diabetic patients should very carefully observe the physician's orders as to rest and exercise. The nurse should note the amount of exercise taken and the effect upon the patient, and under no circumstances should the patient be allowed to become fatigued. Severe athletic games are, of course, strictly forbidden. The weight should always be taken at the same hour, preferably upon arising in the morning. The patient should be weighed naked, or, if in clothes, the exact weight of the clothes recorded. The nurse should see that the necessary foods are kept on hand. Fresh eggs should be carefully selected; bacon and the 5 per cent, vegetables are important elements in most diets. Cream, butter, and olive oil for the day can be measured in the morning and then allowed until used up. It is important for the nurse to familiarize herself with the vegetables containing 5, 10, 15, and 20 per cent, carbohydrate. These are interchangeable so that the patient who is allowed a certain amount of a 10 per cent, vegetable can replace it with one-half the amount of a 20 per cent, vegetable, or twice the amount of a 5 per cent, vegetable, and the same rule applies to DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 345 the interchange of other carbohydrate foods. This allows variety in the diet, which is most important. The vegetables should be very thoroughly cleaned; such as are suitable for salads may be taken as such, but only the tender parts should be used. The other vegetables may be used in stews or in soups, or as purees, the latter made with butter or cream, and these may be rendered appetizing with very little difficulty. Thrice-cooked vegetables have been particularly recommended, and as many of these are low in carbohydrate content they can be rendered practically carbohydrate free. They add an element of bulk to the diet and aid in preventing constipation. These were suggested by Allen, par- ticularly for use in patients who are allowed very little. The vegetables are cleaned, cut up in small pieces, soaked in cold water, strained, put in fresh cold water, and heated to 1500 F. The water is then poured off and replaced by water of the same temperature and then the vegetables are boiled three times, changing the water at the end of each boiling. This process is facili- tated by tying the vegetables in double gauze squares, the corners tied with string, the ends left long enough so that the bundles may be lifted from one container to another. The object in the diabetic diet is to get the patient free from sugar and acid bodies in the urine and to keep him so. For this purpose any one of several definite plans may be followed, depending on the condition of the patient and the experience and judgment of the physician in charge. When the disease is mild, as occurs in many of the old and obese, a restriction of car- bohydrate foods without particular attention to the amount of other foods taken may suffice. According to the plan devised by Allen the patient is made sugar free 346 DIETETICS FOR NURSES. by fasting. The management advised by Joslin consists in a gradual reduction of food until the patient is sugar free, and then in a gradual increase of diet until the patient receives a diet containing I gram of protein per kilogram of the patient's body weight, 3 grams of car- bohydrate, if the patient's tolerance allows it, and a moderate amount of fat. The diet scheme more usually followed at the time of this writing is that advocated by Woodyatt, wherein the patient receives 1 gram of protein per kilogram of body weight and the total diet is made up to equal the patient's caloric needs by giving fat and carbohydrate in such proportions as to prevent the formation of acid bodies. These proportions are approximately such that the number of grams of fat is equal to one-half the number of grams of protein plus twice the number of grams of carbohydrate. Example: For a patient weighing 50 kilograms, a Woodyatt diet giving 30 calories per kilogram, or 1500 calories, would consist of protein 50 grams, fat 118.6 grams, carbo- hydrate 46.8 grams. Several other diet schemes are also in use. But the proportion of protein, fat, and carbo- hydrate in the diet to be given is, after all, the physician's responsibility; it is the nurse's duty to so select the food-stuffs that the total ordered by the physician shall be reached. In certain patients the sugar tolerance may be so low as to forbid the giving of a diet sufficient for the pa- tient's body needs, or the tolerance may be so depressed by acute infection, the strain of surgical operation, the strain of excessive fatigue or of child-birth, or by the strain of continued neglect of dietetic precautions, that dietetic treatment alone will not suffice. It is in these cases that insulin (iletin) is used. Insulin is an extract of the animal pancreas which increases the ability of DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 347 the body to utilize sugar. It was discovered and pre- pared by Dr. Banting and Dr. Best of the University of Toronto and is of the greatest value in the treatment of severe diabetics. It must be given by hypodermic injection and the most rigid asepsis must be observed to avoid infection at the point of puncture. Insulin is a powerful and often dangerous agent. It should only be used under the most competent medical direction. In a patient receiving insulin the diet must be controlled with extraordinary care so that the sugar content of the blood shall not be lowered beyond normal limits. When this occurs, a typical reaction sets in; the patient com- plains of blurring of vision, feeling of weakness or faint- ness, rapidly loses consciousness, has convulsive seizures, and the attack may terminate fatally. This reaction can be controlled by giving sugar, and in cases treated with insulin some readily available form of sugar, and if the physician desires it, the materials for the intravenous infusion of glucose solution should be on hand. In former years diabetes in children was regarded as practically hopeless. With early recognition and very strict treatment many of these patients do surprisingly well and the possession of insulin makes the outlook far less gloomy than it previously was. The diet is along the same line as in adults, but children are rather prone to acidosis and require special care on this account. The nurse in charge of a diabetic child should be particularly careful in the testing of urine, especially for acid bodies. Any unusual drowsiness or sluggishness should be the signal for immediate notification of the physician. The general hygiene of the case is much the same as in adults. Since diabetes is a progressive disease, and since the tolerance is lessened by any strain on the carbohydrate 348 DIETETICS FOR NURSES. Fluid measure scale to convert cubic cen- timeters to ounces or vice versa. Weight measure scale to convert grams to ounces or vice versa. DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 349 metabolism, the responsibility for the progress of the con- dition rests heavily on the nurse in charge. For the use of the nurse the following list of foods, arranged approximately according to the percentage of carbohydrate given on p. 350, will be found of value. At one time substitutes for bread and special diabetic foods were very popular. With more careful attention to quantitative control of diet these are found to be of doubtful value, and many physicians prefer to omit them entirely. Among the foods used are bran bread, Lyster flour, and soy bean flour. Gluten flour and the gluten breads should be avoided as they contain very variable amounts of starch. In using bran, the bran should be washed until the wash water fails to give a blue color with a drop of the tincture of iodin. This is done by placing the bran in a cheese-cloth bag, and tying it to a tap of running water. Saccharin may be used for sweetening. In the latter part of this book certain recipes for special diabetic foods are given. In the mild diabetic a qualitatively limited diet is sometimes used. The nurse may find it both interesting and instructive to study the tables given below, and the diet for such cases as the physician leaves with general orders may be arranged from them. Under no other circumstances should a nurse or other unqualified person attempt to manage the diet of a diabetic, and the physician should always keep in close touch with the case. The nurse will be in a position to sympathize with the patient and to take extra pains with the details of carrying out whatever may be ordered if she will attempt living on a carbohydrate-free diet for a few days. She will learn many things in that way which may not other- wise occur to her. 350 DIETETICS FOR NURSES. STRICT DIET.

DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 351 The following four tables are taken from von Noor- den's article in The Twentieth Century Practice of Medicine: TABLE I. First Group.-Unconditionally Allowable Foods. Fresh meat: All the muscular parts of the ox, calf, sheep, pig, horse, deer, wild and domestic birds-roasted or boiled, warm or cold, in their own gravy or with mayonnaise sauce. Internal parts of animals : Tongue, heart, brain, sweetbreads, kid- neys, marrow-bones-served with non-farinaceous sauces. Preserved meats: Dried or smoked meat, smoked or salted tongue, ham, smoked breast of goose, American canned meats, Australian corned beef. Fresh fish : All kinds of fresh fish, boiled or broiled, prepared with- out bread crumbs or cracker meal, and served with any kind of non-fari- naceous sauce, preferably melted butter. Preserved fish : Dried fish, salted or smoked fish, such as codfish, haddock, herring, mackerel, flounder, salmon, sardellen, sprats, eels, lampreys, etc.; tinned fish, such as sardines in oil, anchovies, etc. Fish derivatives : Caviare, cod-liver oil. Shellfish : Oysters, mussels, and other bivalves, lobster, crawfish, crabs, shrimps, turtle. Meat extracts : Meat peptones of all kinds. Fggs : Raw or cooked in any way, but without any admixture of flour. Fats of all kinds, animal or vegetable. Fresh vegetables: Green lettuce, endive, cress, spinach, cucumbers, onion, leek, asparagus, cauliflower, red and white cabbage, sorrel, French beans. The vegetables, so far as they are suited to this mode of prepa- ration, are best cooked with meat broth or a solution of Liebig's extract and salt, and covered plentifully with butter, lard, suet, or goose fat. The addition of flour is not permissible. Preserved vegetables : Tinned asparagus, French beans, pickled cucum- bers in brine or vinegar, mixed pickles, sauer kraut, olives. Spices: Salt, white or black pepper, Cayenne pepper, curry, cinna- mon, cloves, nutmeg, English mustard, anise seed, caraway seed, pars- ley, dill, borage, pimpernel, laurel, capers, chives, garlic, etc. Many of these spices contain, indeed, a rather large percentage of carbohy- drates, but they are added to the food in such small quantities that this may be disregarded. 352 DIETETICS FOR NURSES. Soups: Clear soups and broths, with or without eggs, marrow, fresh or dried vegetables (Julienne), clear turtle soup, etc. Cheese. Stracchino, Neufchatel, old Camembert, Gorgonzola, and all other fatty or so-called cream cheeses. Beverages : All kinds of natural or artificial carbonated waters, either clear or with lemon juice and saccharin or glycerin, or with rum, cognac, whisky, arrack, cherry brandy, plum brandy, Nordhauser, rye whisky, etc. Light Moselle or Rhine wines, claret, or Burgundy in amounts pre- scribed by the physician. Coffee, black or with cream, without sugar, but sweetened with saccharin if desired. Tea, clear or with cream or rum. Second Group.-Foods Permissible in Moderate Quantities. These contain carbohydrates, but in so little amounts that they need not be considered, and demand no compensation by a reduction in the allowance of bread. Some of the articles contain a rather large per- centage of carbohydrates, but the absolute quantity in which they are consumed is small. The amounts here given have been fixed by practical experience, and it will seldom be found necessary to increase them. Of the dishes here given, when they are allowed at all, only a few-from two to four-are to be selected each day. It is possible in this way to secure a great variety in the patient's dietary. Internal parts of animals : Calves' liver, giblets-up to loo gm. Sausage : Liver sausage, preferably the fatty kinds, liver sausage with truffles, black pudding-90 gm. Meat sausage-80 gm. German sau- sage, Frankfurter sausage, and the like, brawn, head-cheese, sausage- meatballs-100 gm. Patties : Pate-de-foie gras, potted beef, ham, tongue, salmon, lobster, anchovies, etc.-| to I tablespoonful. English sauces, such as Worcestershire, Harvey, beefsteak, anchovy, lobster, shrimp, India soy, China soy-I teaspoonful. Cream, from 4 to 6 tablespoonfuls a day. Cocoa, prepared without sugar-25 gm. Cheese: Emmenthal, Romadur-60 gm.; Gervis, Stilton, Brie, Hol- land, Gruyere-50 gm.; Edam, Cheddar, Gloucester, Roquefort, Par- mesan-30 gm.; Cheshire, 25 gm.

Raw vegetables : 8 radishes ; 2 sticks of celery ; 2 medium-sized toma- toes. Nuts : 2 walnuts ; 6 hazelnuts ; 3 almonds; a thin slice of cocoanut; 8 Brazil nuts. Fresh fruits: I thin slice of melon; 1 small tart apple; I or peaches ; 1 spoonful of raspberries or strawberries ; 4 spoonfuls of cur- rants ; 6 green gages; 12 cherries; | of a medium-sized pear; corre- sponding amounts of other fresh fruits. TABLE III. Third Group.-Conditionally Allowable Foods. The conditions under which dishes from the following table are per- mitted is that an equivalent shall be deducted from the allowance of bread. The amounts given below are the equivalents of 50 gm. of white bread, containing about 30 gm. of starch. Advantage is taken of the fact that larger amounts of certain carbohydrates (cane sugar, milk sugar, fruit sugar, etc.) maybe allowed than of starch. Some of the dishes given in the preceding table appear again here because, if they are eaten in large quantities, an account must be taken of the carbohydrates which they contain: I liter of milk (sweet, sour, or buttermilk). 11 liters of kumiss, prepared in the Russian way. I to 1J liters of kefir, fermented for at least two days and prepared without the addition of sugar. 1 liter of cream. 60 gm. of rye bread, Graham bread, or Hamburg pumpernickel. 65 gm. of Westphalian pumpernickel. 100 gm. of aleuronat bread, prepared after Ebstein's formula (con- taining 27.5 per cent, of carbohydrates and 32 per cent, of vegetable albumin ; the aleuronat breads are very vari- ably compounded). 35 gm. of zwieback and simple coffee cakes, made without sugar. 30 gm. of English cakes of various sorts. 30 gm. of " Eich el-cacao " (Stoll werck's). 50 gm. of chocolate (Stollwerck's). 40 gm. of chocolate (French make). 354 DIETETICS FOR NURSES. 40 gm. of chestnuts shelled or 60 gm. unshelled. 35 gm. of cane sugar, brown sugar, or rock-candy. 35 gm. of sweet preserves. 40 gm. of fruit sugar. 40 gm. of milk sugar. 50 gm. of fruit jam. 40 gm. of honey. 40 gm. of flour-wheat, rye, barley, buckwheat, millet, or oatmeal or cornmeal. 45 gm. of bean, pea, or lentil flour. 35 gm. of starch preparations, potato, wheat, or rice, starch, tapioca, sago, maizene, mondamin, etc. 35 gm. of rice. 35 gm. of farinaceous preparations - noodle, macaroni, oatmeal, grits, barley. 50 gm. of lentils, peas, beans (weighed dry). 100 gm. of green peas. 180 gm. of new potatoes. 140 gm. of winter potatoes. 120 gm. of apples, pears, green gages, plums, damsons, mirabelles, apricots, cherries, grapes. 200 gm. of strawberries, raspberries, gooseberries, mulberries, cur- rants, blackberries, whortleberries, blueberries. 3 peaches. 40 gm. of figs. 3 bananas. A handful of walnuts, hazelnuts, almonds, or Brazil nuts. | liter of beer of any sort. £ liter of sweet wine. DISEASES IN WHICH DIET IS A PRIMARY FACTOR 355 TABLE IV. Fourth Group.-Especially Valuable Foods. The great value of the articles contained in the list on the following page, of which, however, there is but a small choice, is due in part to the high percentage of protein and in part to that of fat. The propor- tion of albumin and fat is given for each too gm. of the food substance. Some contain carbohydrates also, the percentage of which is given for the sake of completeness, but its nutritive value is not counted. ioo Gm. Protein. Fat. Carbo- hydrate. Calorie value.

Sydenham said: " Great eaters are liable to gout, and of these the costive more especially. Eating as they are used to eat when in full exercise, their digestion is naturally impaired. Even in these cases simple gluttony and the free use of food, although common incentives, by no means as frequently pave the way for gout as reckless, inordinate drinking." This statement is as near the truth as anything that has been said since. 356 DIETETICS FOR NURSES. The causes of gout are alcoholism, overeating, heredity, indigestion, constipation, and it is also sometimes seen in leadworkers. In gout there is a disturbance of metabolism, particu- larly that of the nitrogenous elements, and especially of what is known as the purin nitrogen. (See Purin Metab- olism.) In gouty individuals there is retention of various products of metabolism in the body, and it is generally advised that foods containing purin bodies should be re- duced or even omitted. The diet for the gouty should be always carefully supervised by the physician. In the acute attacks the diet should be liquid or semi- solid. Milk, bread and milk, and farinaceous gruels are usually prescribed. After several days the light meat of boiled or baked fish is allowed or a little easily digestible meat. The increase in the diet is always ordered by the physician. Chronic Gout.-The diet here is also to be made up of simple plainly cooked food, all rich and indigestible dishes being prohibited. There is often a peculiar per- sonal idiosyncrasy in regard to certain articles of diet, and this will largely influence their use. As a rule, how- ever, the following outline will suffice for the guidance of the patient: Soups of the plainest sorts may be taken, especially those consisting largely of vegetables. Yeo has sug- gested the use of vegetable purees to which beef extract has been added to give them a flavor of meat. Milk is valuable in all cases, and where it disagrees it may be skimmed, peptonized, or diluted with a carbonated water. Bicarbonate of soda may be added when it is desired to make the milk alkaline; i to 5 gr. to the ounce should be used according to requirements. DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 357 Meat and fish may be taken daily, preferably not at the same meal. Fresh beef, mutton, and the like are the most suitable meats, and poultry may be allowed for the sake of variety. Eggs may be taken in moderation. Twice-cooked meats should be avoided, as should dried, smoked, or pickled meats, as well as pork and veal. Garrod allows bacon at breakfast, but fats are, as a rule, to be avoided. Under special conditions, when the patient's nutrition is poor, they may be given if tolerated. Only the lighter varieties of fish should be given, boiled being preferred to fried fish. Oysters and clams may be taken, the hard portion being discarded. Salt fish, as well as mackerel, salmon, eels, and all other heavy fish, should be prohibited. Crabs, lobster, shrimp, and the like, as well as sauces, are usually to be avoided. Vegetables, when they are easily digested, may be permitted. Peas, beans, potatoes, artichokes, salsify, onions, turnips, greens, cauliflower, and cabbage are all allowable, as are likewise celery, lettuce, and similar green vegetables. Carrots and beets, because of the sugar they contain, and asparagus, tomatoes, rhubarb, and sorrel, on account of their acid, are best avoided. All preserved and pickled vegetables, as well as the coarse and fibrous portions of all vegetables, are to be omitted from the dietary. The use of sugars and sweets is a very important part of the dietary, for, as a rule, they are a source of much trouble. Each individual differs in regard to the amount which may be allowed. Starchy foods may be allowed according to the patient's ability to digest them, without 358 DIETETICS FOR NURSES. causing fermentation and flatulence, and this also varies greatly in different individuals. Fruit is best taken in the morning or during the in- terval between meals. It shouid, as a rule, be avoided during the latter part of the day, after full meals or with wine. Among the most suitable fruits for the gouty are oranges and grapes. Baked apples or stewed fruit may be taken. The sweet juice of the latter is, however, best avoided. Garrod advises the avoidance of all stone fruits, but allows baked apples and pears and straw- berries sparingly. Fothergill suggested that bicarbonate of soda be taken with stewed fruit to correct the acidity. Opinions differ regarding the use of fruit by the gouty. If any particular fruit disagrees with a patient it should, of course, be avoided. Patients often manifest idiosyn- crasies respecting fruits, and these furnish a guide to their suitability. Gout is also studied nowadays with a view of determin- ing the amount of nitrogen chat can be utilized in a given case with safety. Sometimes a purin-free diet is ordered, the following being a sample: PURIN-FREE DIET. Breakfast: Eggs, 2. Toast, 75 gm. Butter, 25 gm. Milk, 6 oz. Dinner: Oatmeal or rice, 75 gm. Potato, 150 gm. Green vegetable, 150 gm. Butter, 75 gm. Toast, 100 gm. Supper: Eggs, 2. Shredded wheat, 100 gm. Butter, 25 gm. Milk, 6 oz.

About 6o per cent, of the purin bodies eaten appear in the urine as uric acid. The substances in tea, coffee, and cocoa are not excreted as uric acid, and these bever- ages may be allowed. Meat extracts, bouillons, dish gravies, and the outside of roasts should be avoided. Relishes containing mustard and spices and the various catsups and appetizing sauces should be avoided, as should radishes, water-cress, garlic, and green peppers, not on account of their forming uric acid, but because they irritate the kidneys. When gout is complicated with obesity, diseases of the kidneys, diseases of the stomach or any other disease, special diets are ordered. Arthritis Deformans.-In this disease there are deformities of the bones which are sometimes con- founded with gout. The diet probably has no influence whatever over this disease. Instead of restricting the diet, it should be as nourishing as possible. 360 DIETETICS FOR NURSES. Scurvy or Scorbutus.-This disease occurs in adults where there is a deficiency of fresh food. It is the scourge of armies, and formerly was frequent among sailors. To prevent it fresh food should be given. Canned food, while not an ideal preventive, is useful. Lemon or lime juice, vinegar, and onions are especially valuable as preventatives. The treatment of the disease, when it occurs, is chiefly dietetic, and consists in giving a good, nutritious diet with fresh fruits and vegetables, fresh meats and the like. The above-mentioned preventatives may be used where the other fresh foods are not available. Infantile Scurvy (Barlow's Disease}.-Scurvy is fre- quently seen in infants, especially between the sixth and the fifteenth month. In almost every case improper feeding is the cause. It has even occurred where the child was breast-fed, but more often from the following feeding, in the order of their frequency: the proprietary infant foods, sterilized milk, condensed milk, and Pas- teurized milk. The treatment is very satisfactory, and consists in placing the child upon a proper diet and giving in addition fresh orange juice, from | to 3 or 4 oz. daily. The juice of any fresh ripe fruit, as of peaches or grapes, may be used instead. OBESITY. There is probably no condition that has been more widely discussed by laymen of both ancient and modern times than obesity, for no disease is more thoroughly associated in the lay mind with its proper causes and its relations to diet than this " oily dropsy", as Bryon calls it. The accumulation of fat is associated with increasing years, but it is by no means confined either to old or DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 361 middle age, as is exemplified in the fat children familiar to all; obesity may be a plague even of infants. The causes of obesity are so well known as to require only passing mention. About 50 per cent, of cases owe their primary origin to hereditary causes. Women are more frequently affected than men. With the advance of years, in some there is a tendency to accumulate fat. Overeating and overdrinking have been named as cau- sative factors, especially when combined with a quiet, sedentary life. The fats and the carbohydrates are the principal ele- ments in the diet that are apt to be converted into fat; but proteins also, if the supply exceeds the demand and assimilation is active, will be converted into body-fat and stored up in the subcutaneous tissues. The liver and the heart are also converted into storehouses for fat, and later there may be a fatty degeneration of both organs, as well as of the coats of the arteries. The dangers accompanying the excessive accumulation of fat are manifold, and include a large number of dis- eases that may be influenced by it either directly or in- directly. These will be discussed when the indications for reducing the weight of patients are considered. Weak heart, anemia, gout, and diabetes are among the most fre- quent diseases with obesity. Reduction cures of many kinds are vaunted by their respective originators. Ebstein has summed up the whole matter in the following sentence: " Corpulence can only be permanently cured by a permanent change of life and diet regulated by physiologic principles." Reduction of weight is in many cases contra-indicated, and a reduction cure should never be undertaken without the advice of a physician. In women especially reduction 362 DIETETICS FOR NURSES. may be a cause of hernia, of dislocation of the kidney, or of the uterus, and may also bring on gall-stone colic in those who have gall-stone disease. In old people re- duction cures are not, as a rule, advised. In many slight cases all that is needed is a regulation of the diet and life so as to prevent any further increase. Reduction may be of especial benefit in stout individuals with heart disease, and a method known as " Oertel's method," which combines diet and exercise, is usually followed. Reduc- tion is also useful in some cases of respiratory disease in very stout persons. Bronchitis and asthma may be men- tioned in this connection. Where the patient has any disease interfering with locomotion, the diet should be so arranged that there will be no excessive accumulation of fat, as the added weight may be the cause of making the patient helpless. A much discussed point is whether it is possible to reduce any special part of the body more rapidly than the remaining parts. This is a method often sought by women who have borne several children and who have large deposits of fat in the abdominal walls, causing an unsightly prominence of the abdomen. If the fat is re- duced slowly, every part of the body, including usually the abdomen as well, will be reduced simultaneously. If it is reduced rapidly, it seems to be removed principally from certain parts of the body, as the neck, breasts, arms, and calves of the legs. Certain advocates of massage claim that the massage of the parts will cause a more rapid reduction. Von Noorden had one arm of an obese patient massaged for six weeks. At the end of that time the arm that had been massaged had increased IJ cm. in circumference, whereas the arm that had not been mas- saged remained the same. DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 363 Massage of the abdomen during a reduction cure may exert a beneficial effect by relieving the constipation, which is apt to be troublesome. Exercise is still more potent, particularly for reducing the abdomen. This is accomplished by standing erect and then bending forward in an effort to touch the toes with the tips of the fingers. Too much should not be expected from this, even when persisted in faithfully. Prophylaxis of Obesity.-Where a tendency to obesity exists the fat-forming foods should be partaken of but sparingly, and sufficient outdoor exercise taken to keep the weight within reasonable limits. The fat- forming foods are fatty foods of all kinds, the sugars and starches. Dietetic Treatment of Obesity.-There are numer- ous methods of diet. The method to be used in any given case is to be determined by the physician. These reduction cures are frequently referred to as Banting cures. The Banting method was that used in the case of a Mr. Banting, by his physician, Dr. Harvey. It was in great vogue some years ago, and the name became erroneously applied to many other methods. It is too severe for the average patient. Banting Diet for Obesity (Yeo).-" Breakfast, 9 A. m. : 5 to 6 oz. of animal food-meat or boiled fish (ex- cept pork or veal); a little biscuit or 1 oz. of dry toast- 6 to 7 oz. of solids in all. A large cupful of tea or coffee (without milk or sugar)-9 oz. of liquid. "Dinner, 2 p. m. : Fish or meat (avoiding salmon, eels, herring, pork, and veal), 5 to 6 oz.; any kind of poultry or game. Any vegetables except potato, parsnips, beet root, turnips, or carrots. Dry toast, 1 oz. Cooked fruit, 364 DIETETICS FOR NURSES. unsweetened. Good claret, sherry, or Madeira, io oz. Total of solids, io to 12 oz. " Tea, 6 p. m. : Cooked fruit, 2 to 3 oz.; a rusk or two- 2 to 4 oz. of solids; 9 oz. of tea (without milk or sugar). " Supper, 9 p. m. : Meat or fish, as at dinner, 3 to 4 oz. Claret or sherry and water, 7 oz. . "This allowed only from 21 to 27 oz. of solids per diem, of which 13 to 16 oz. consisted of animal food and only 2 oz. of bread; the rest consisted of fruit and fresh vegetables. There was the strictest possible exclusion of starches and sugar. "The total fluid was limited to 35 oz." Oertel'S method is a combination of diet and exer- cise, and is especially applicable to patients with disturb- ances of the circulation. The quality and quantity of food and the amount of fluid are carefully regulated by the medical attendant according to the patient's condition. Ebstein's method consists in giving a diet in which the carbohydrates are reduced, but in which considerable amounts of fats are allowed. The custom of giving fatty food in such cases is as old as Hippocrates, for he says, " The food shall be fat in order to satiate quickly." This method is, however, based on an erroneous opinion. In general it may be stated that the diet should be limited in amount, the starches and sugars reduced to a minimum, fats reduced or omitted altogether, and the amount of fluid cut down to a very small amount. The food given consists of meat, eggs, fish, fruits, and green vegetables. Sufficient exercise is taken to keep the weight down to the required number of pounds. When obesity is complicated with any other disease, the diet may be a point of considerable difficulty. DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 365 DIET FOR LEANNESS. In a general way the indications for fattening thin people is the reverse for the diet used in obesity. Many individuals are thin as a matter of constitution, and such as these can not be fattened by any means. There may be some special cause for the leanness, and when the physician can discover this and remove or relieve it, the patient may be increased in weight. Patients emaciated from acute illness are readily fattened. The patient should lead a quiet outdoor existence, free from care or excitement, and should get sufficient sleep. The meals should be ample, and as much carbohydrate and fatty food taken as possible. Cream, milk and cream, butter, cocoa, chocolate, bread, cereals (well cooked), farinaceous puddings, potatoes, legumes, and sweet fruits should all be partaken of in abundance. All sweets- honey, syrups, cakes, and the like-may be taken if they agree with the digestion. Beer, especially the darker varieties, porter and brown stout are useful. Sweet wines are sometimes ordered, and malt extracts where it is not desirable to use alcoholic beverages. Strong alcoholic drinks, acids, spices, and many green vegetables are for- bidden. Certain skin affections are caused directly or indirectly by dietary errors; others are prolonged or intensified by an improper diet, and still others are connected in some way with diseases of the alimentary tract or with dis- turbed metabolism. Eczema.-All food which is known to cause erythema or urticaria in the individual should be avoided, as should all food which is liable to undergo fermentation in the DIET IN SKIN DISEASES. 366 DIETETICS FOR NURSES. intestinal tract or which will produce indigestion. Irri- tating spices and alcoholic beverages are usually omitted from the dietary. The meals should not be too large, should be taken at regular intervals, and a simple varied dietary should be followed. Gouty and obese patients are usually ordered diets suitable for their disease. A milk diet is frequently used in persistent cases. In infants it is important to have the digestion in per- fect order. Urticaria (Hives).-Many articles of diet cause hives in certain individuals. Among the most frequent causes are strawberries, oysters, crabs and other shellfish. Partially spoiled or stale articles may also be a cause. Acne.-All indigestible articles of food are to be avoided, and the diet should consist of easily digested fresh food. Excessive quantities of fat should be avoided. ACIDOSIS. The blood has a slightly alkaline reaction and nature has made provision for keeping it so by having alkaline bases in reserve in the body tissues and fluids. Acidosis is seen in the course of various diseases and nutritional disturbances and may be caused by too little food and fluid, as in starvation, also in vomiting and diarrhea; where the body fails to neutralize the acids by the production of ammonia, as in nephritis; where the fats are not metabolized to carbon dioxid and water, but form organic acids, as in diabetes, cyclic vomiting, in- fections, and some other diseases; and where the acids are not properly eliminated. Formerly acidosis was combated by the administra- tion of sodium bicarbonate, and this is still used in cer- tain cases, especially where the acidosis is not due to the DISEASES IN WHICH DIET IS A PRIMARY FACTOR. 367 formation of organic acids. The present-day recom- mendations are the administration of large quantities of water either by mouth, rectum (Murphy drip or injec- tion), subcutaneously, or intraperitoneally. For the last two normal salt or Ringer's solution should be used. In addition to this glucose is given in the same manner. By mouth in 5 or 10 per cent, solutions; by rectum in 4 or 5 per cent, solutions; intravenously, 5 to 10 per cent, in normal salt or in Ringer's solution from 2 to 10 ounces, according to the size of the child; intraperitoneally 2 per cent, glucose in half-strength Ringer's solution, 2 to 16 ounces at a time, according to the age of the child. In selected cases sodium bicarbonate may be given by mouth, 10 grains to | dram at a time. By rectum 4 per cent, sodium bicarbonate in 4 per cent, glucose solution, or in plain water, may be used. Intravenously a 2 per cent, solution may be given. Too much sodium bicar- bonate may cause symptoms, tetany, convulsions, edema, and vomiting. If these occur, water should be admin- istered freely, and in convulsions magnesium sulphate may be given subcutaneously, using an 8 per cent, solu- tion or, as Blackfan suggests, for the relief of cerebral nephritis intravenously, in a 2 per cent, solution given at the rate of 10 c.c. per minute in amounts of about 15 c.c. per kilogram of body weight. This may be re- peated at intervals of six to twelve hours if necessary. CHAPTER XIX. SPECIAL DIET CURES. The Milk Cure.-Milk is used extensively as a food during illness, and it has also been warmly advocated as a curative agent, especially by Karell, of St. Petersburg, and Weir Mitchell. Physicians may prescribe an exclusive milk diet in a large number of diseases, chief among which are diseases of the kidneys, liver, heart, and intestines. It is also at the outset of the rest cure. Method of Administration.-Well-skimmed milk from the country, as fresh as can be procured, is used. Later on the unskimmed milk is often ordered. Karell begins with from 3 to 6 oz. three or four times a day, and in- creases the amount gradually. The milk is to be taken slowly, at regular intervals, allowing it to mix with the saliva. In winter it is warmed, and in summer given at the room temperature. After a week, if the stools re- main solid, the quantity is increased, 2 liters (quarts) a day being given during the second week in favorable cases. The regular hours are to be insisted upon. If the milk causes diarrhea it is boiled. Constipation is regarded as a sign that the milk is agreeing, and the bowels may be moved if necessary by laxatives or enemata. Small quantities of coffee mixed with the morning's milk, or stewed prunes or baked apples in the afternoon, are useful in relieving constipation. If there is a flatulence, it usually means that too much 368 SPECIAL DIET CURES. 369 milk is being given or that it is not properly skimmed. If there is thirst, plain water or a carbonated water may be given. Lime water or one of the infant foods may be mixed with the milk to render it more digestible. During the second or third week, if there is an irre- sistible desire for food, a little salt herring or a bit of stale bread with salt may be given. Once a day milk soup thickened with a cereal may be given. After five or six weeks the ordinary diet is gradually resumed, but large quantities of milk are still taken. During the first week the milk causes slight drowsi- ness, a coated tongue, and a peculiar taste in the mouth. The stools are light yellow and resemble the milk stools of infancy. The urine is increased in quantity. There is a slight initial loss of weight, but an increase later on in the cure. Salt-free Diet.-The average daily diet contains about i gram of sodium chlorid-that is, common table salt-in the original composition of the food, and io to 20 grams are added daily as seasoning. It has been found that by adding salt to the diet of a patient suffering with certain forms of nephritis that the edema, if present, could be increased, or, if it was not present, it could be produced. This led to the reduction of the quantity of salt taken by edematous patients, and in some instances with rather remarkable results. Some similar results have been obtained in the edema due to heart disease, and a salt-free diet has also been advised in a great many other conditions. In cases with kidney trouble, where there is constant thirst, a salt-free diet is often of great benefit, the sipping of water at short intervals is avoided, the mouth becomes moist and more comfortable. It is a good plan to omit the salt cellar from the table or tray, 370 DIETETICS FOR NURSES. and if no effect is noted the quantity of salt put in the food during its preparation should be greatly reduced or omitted altogether. Salt-free diet may be easily arranged with the coopera- tion of the cook, and may consist of the following articles of diet, from which the patient can very easily subsist. These can be modified according to the disease for which the patients are being dieted: Bread should be made without salt. The average bread contains about io grams for each kilogram, some- times more. The bread which has not had salt added to it contains about 0.7 centigrams per kilogram. SALT-FREE DIET. Bread. Meat.

Fresh eggs may be taken in any form desired, each egg contain- ing about 25 centigrams. Fresh butter, fresh cream, and saltless cheese may be used freely.

Sweetmeats, pastry made without salt, and raw or cooked fruit may also be used. Chocolate will be found of especial value. Tea, coffee, and beer, or even wine may be taken as far as the amount of chlorids which they contain are concerned. Other Diet Cures.-Many other cures are used in various parts of the world. Almost every article of diet has at one time or another been vaunted as a " cure." Whey, to which alkaline mineral waters have been added, is sometimes prescribed with plenty of fruit and vegeta- bles and little meat Kumiss is used in Russia. Grapes, apples, and other fruits are used in certain countries. A " dry " cure, where the amount of liquid is greatly reduced, is sometimes prescribed, especially for aneurism. A meat- and-hot-water cure is used for stomach disorders. The Kneipp cure consisted chiefly of a diet of fruit, bread and milk, with small quantities of meat and vegetables. The cure also directs that the patient walk barefooted in the grass while the dew is still on it. CHAPTER XX. DIETETIC MANAGEMENT OF SURGICAL CASES. Surgical operations that must be performed immedi- ately, of course, admit of no preparation. Most opera- tions, however, may be postponed for several days or longer, thus enabling the patient to be put in good con- dition by rest, preferably in bed, and a nourishing, easily digested diet. The value of the rest in bed is greatly augmented by massage, electricity, and baths where the condition of the patient admits of their use; by tonics; and by laxatives to correct the tendency to constipa- tion that usually exists. Before the Anesthesia.-Wherever possible, before an anesthetic is given to children and even to adults, it is well to give bicarbonate of soda three times daily for two days preceding operation, and at the same time to administer the equivalent of one-half dozen lumps of sugar each day. The amount of soda may be varied according to the size and age of the individual, I tea- spoonful three times a day for an adult of about 150 pounds, and proportionately less in children. This will practically do away with the severe acidosis and vomit- ing so frequently met with, particularly after ether anes- thesia in younger people. Anesthesia and Diet.-When an anesthetic is to be administered a routine somewhat as follows should be carried out whenever the circumstances allow: The day preceding the operation the patient should be kept quiet; 373 374 DIETETICS FOR NURSES. the bowels should be thoroughly emptied by means of a saline purge, and the diet should be light and easily digested. The supper should be a light one, and nothing but water should be given for six hours at least before operation if possible; but water may be given up to the time of operation. At the time of anesthesia the stomach should be empty. This is important, as it lessens the nausea ex- perienced by many patients after anesthesia, and also lessens the danger of vomiting food during an operation, an accident which may cause severe coughing if the food is drawn into the larynx, or may cause pneumonia if it is drawn into the lungs. The coughing and vomiting may interfere seriously with the operator. If it is necessary to administer an anesthetic after a full meal and circumstances permit, an emetic may be given to empty the stomach before the operation is begun, or it may be better to wash out the stomach. Nausea is liable to follow after anesthesia, particularly after the administration of ether; this is discussed below. If nausea does not occur, a cupful of weak tea or of diluted milk may be given two or three hours after the operation, and if that is retained, milk may be given as often as every three hours if desired. A patient suffers more from too much food than from too little. For supper, bread and milk or cocoa or a slice of toast and a cupful of weak tea may be allowed. It is well, however, to wait until the following day before giving anything more. On the following day, if there is no nausea or other untoward symptoms, a light breakfast may be given, and after that as rapid return to an ordinary diet as cir- cumstances permit may be made. If there is nausea, or after laparotomies, operations about the head, and other operations as outlined below, especial care must be taken with the diet of the patient. DIETETIC MANAGEMENT OF SURGICAL CASES. 375 Diet After Operation.-The diet following opera- tions should be supervised by the surgeon himself or by an assistant especially trained for the purpose. In opera- tions about the mouth, as for hare-lip, and on the alimen- tary tract, the management of the diet is as of much im- portance as the operation itself. In order to avoid the interference of well-intentioned but misguided friends, many surgeons refuse to operate except in a hospital unless the patient is in a condition which does not per- mit of his being moved. It should be remembered that confinement to bed for weeks after an operation greatly impairs nutrition, and every effort should therefore be made to get the patient in the open air, either on his bed or in a wheel-chair. Massage and electricity are employed in suitable cases to maintain the nutrition. In patients who are up and about no especial diet is, as a rule, necessary, except after operations about the mouth, larynx, or alimentary tract. The diet should be as simple and as nutritious as possible, usually that of the ordinary individual. Patients suffering from diabetes, gout, dyspepsia, as well as vegetarians, require especial care, and the physician will in such cases give explicit directions concerning the diet. Children should be fed according to the usual rules for them, but it is a good plan to have the children, and especially infants, in the hospital a few days, so as to get them accustomed to the diet on which they will have to live. Those habituated to the daily use of alcohol for years should receive a moderate average amount, lest nutrition be interfered with or delirium develop. The physician will regulate the dosage in these cases. 376 DIETETICS FOR NURSES. Diet After Operations About the Head.-For the first few days the diet should be light-usually liquid -especially if the brain has been affected, and as nutri- tious and as easy of digestion as it is possible to make it. The bowels should be kept open. No alcohol is allowed except in cases of habitues or on the surgeon's direction. If the patient is unconscious, it may be neces- sary to feed him with a nasal or stomach tube. In some cases rectal feeding is used. After brain operations, where there are no unusual symptoms, the diet may be made semisolid, or even an easily digested solid diet may be allowed after two or three days. Milk toast, junket, bouillon and egg, soft- boiled or poached eggs, squab, chicken, and the like are allowable. The diet should be light, but sufficient in quantity, until the patient is up and about, when it may be increased to nearly the normal diet. In operations of a plastic nature about the face, where the taking of food or vomiting is liable to open the wound, the food should be given by the rectum until all danger of the vomiting is past and until the patient can masticate and swallow without fear of injuring the part. Diet After Hare-lip and Cleft Palate Opera- tions.-Following these operations especial attention to the diet is necessary. The child should be taught to take food from a spoon or large medicine-dropper before operation. If the breast milk is used, it should be drawn from the breast by means of a pump and given with a spoon or dropper. Cold sterilized milk or modified milk should be used in these cases until the patient is able to take other food. Nasal or rectal feeding may be neces- sary in some cases. DIETETIC MANAGEMENT OF SURGICAL CASES. 377 Diet After Esophageal or Laryngeal Opera- tions.-The diet in these cases is of the utmost impor- tance and depends very much on the operator and the operation done. The surgeon's directions will always be explicit in such cases. Diet and Laparotomies.-One or two days before the operation the bowels should be cleansed thoroughly by a saline or other purge, and in the case of an abdomi- nal or pelvic operation an enema or two is ordered in addition, not only to secure cleanliness, but to obtain rest for the bowels. The washing out of the bowel should be performed early on the morning of the operation, at six or seven o'clock, or at least three hours before the opera- tion. No food should be given for at least four hours previous to the operation. Many surgeons operate early in the morning, before the patient has broken his fast. Others operate later in the day, and allow the patient a glassful of milk or some such light nourishment on awakening. As a rule, nothing should be given by the mouth for twenty-four hours. Some operators allow very small quantities of carbonated water or iced water or very hot water, or if the patient is very weak and in need of nour- ishment, teaspoonful doses of milk may be ordered with or without lime water or a carbonated water. Hot weak tea, or if a stimulant is needed, hot black coffee, may be administered or alcoholic stimulants may be used. In these cases as in all others the nurse acts only under the direct orders of the surgeons. Interference or injudi- cious feeding may prove fatal. From 5 to 10 oz. of liquid food are generally allowed on the second day, and from 10 to 15 oz. on the third day. On the fourth day, if there are no outward symptoms, a soft diet may be 378 DIETETICS FOR NURSES. ordered, and after a week or ten days a gradual return to an ordinary diet may be made. This varies, of course, with the operation done and the progress of the patient. Nausea and Vomiting1.-Many operators wash out the stomach after the operation and before the patient recovers from the effects of the anesthetic. This often prevents nausea, especially if ether has been given. The vomiting and nausea may be transitory, or it may last for days or a week or more and even threaten the patient's life. While the vomiting is active no food should be given by the mouth. If it persists and the patient is weak, rectal feeding is usually resorted to if the operation per- mits of it. Various drugs are used to relieve the vomit- ing, and sometimes a glassful of hot water is given or the stomach is washed out. As a rule, total abstinence from all food and drink by the stomach is the best way to manage these cases. Thirst.-This may be almost intolerable. The patient may drink the water from hot-water bottles if not watched. High rectal enemata of hot water are sometimes used while the patient is still on the operating-table, and do much toward relieving the thirst of the patient. If allow- able, rectal injections of normal salt solution may relieve thirst. As a rule, thirst is best allayed by using the con- tinuous rectal injection of water as recommended by Murphy. Sips of hot water or of hot weak tea are fre- quently given by the mouth. Carbonated water is some- times used, but care should always be taken to allow it to effervesce partially before giving it, lest the gas accu- mulate in the stomach. Care of the Bowels.-The bowels are usually DIETETIC MANAGEMENT OF SURGICAL CASES. 379 moved about the third day after an operation. Some- times it is desirable to have them moved before; some- times to allow them to remain quiet for several more days. The surgeon should always be consulted about this if specific orders have not been given. Dietetic Management of Shock.-The patient will, as a rule, be less shocked if in good condition than if unprepared for the operation as outlined above. After the operation, in addition to the usual means of external heat and the like, stimulating or nutrient enemata may be given. The first enema is sometimes given while the patient is still on the table. A stimulating enema for an adult may contain 2 oz. of brandy, 20 gr. of carbonate of ammonium, with sufficient water or beef tea at ioo° F. to make 8 oz. Another stimulating enema consists of 1 oz. of brandy, the white of an egg, 3 oz. of milk, and a pinch of salt. Diet After Operations on the Various Organs.- After operations on the liver the diet consists largely of protein and carbohydrate food. Fats are, as a rule, not well borne, and are limited in amount or not given at all. Water is the first thing of importance, and should be forced. It has been demonstrated that if a patient suffer- ing with gall-bladder disease does not void at least 500 cc. of urine in twenty-four hours, mental symptoms are almost certain to develop. After operations on the pancreas the amount of fat is limited or omitted altogether from the dietary. The use of artificially pancreatized food has been suggested. After operations about the kidney the diet should be bland and unirritating, such as has been suggested in chronic or even in acute nephritis (inflammation of the kidney). All foods known to be irritating to the kidney should be withheld. (See Nephritis.) 380 DIETETICS FOR NURSES. Diet After Operations on the Stomach.-The stomach and the upper part of the small intestine may be rendered sterile or nearly so, and this fact is taken advantage of by many operators in surgical procedures about the stomach. Finney uses the following diet: For several days prior to the operation the stomach is washed out twice daily with sterile water, the patient is given sterile liquid food served in sterile dishes. Before taking food the mouth is thoroughly cleansed with a I per cent, solution of carbolic acid. The food is usually given every two hours. For four or five days after the operation rectal feeding is employed. Normal salt solution enemata are alternated with nutrient enemata every four hours. On the fifth or sixth day egg albumin is given in teaspoonful doses, gradually increased to | oz. every two hours if it is well borne, and finally to I oz. every two hours on the sixth day, 2 oz. on the seventh day, and 4 oz. every three hours on the tenth day. On the twelfth or thirteenth day the patient is given a soft-boiled egg, and the follow- ing day soft food, and on the eighteenth day light solid food. Operators vary a great deal regarding the feeding of their stomach cases. Some allow eight days to elapse before beginning mouth-feeding, while others begin a day or two after the operation. Diet After Operations on the Intestines.-After opera- tions on the upper part of the intestine the feeding is the same as after stomach operations. The food should be such that but little residue will be left in the intestine. After ordinary appendix operations the patient may be given liquid diet the second day after the operation; on the third day a soft diet may be allowed, and solid food DIETETIC MANAGEMENT OF SURGICAL CASES. 381 given on the sixth day. On the other hand, if the opera- tion has been a serious one and a large pus cavity has been evacuated, rectal feeding may be necessary for five or six days, and the return to a solid diet may require weeks. After operations on the rectum the patient is generally given a liquid diet for four or five days, after that a soft diet, and finally in seven days or longer solid food may be prescribed. Feeding Through Gastric or Intestinal Fis- tulas.-After gastric or intestinal fistulas have been made the patient may, if necessary, be fed through these openings as early as a few hours after the operation. At first only very small quantities of liquid food are given at frequent intervals. Kehr advises alternately, every two hours, J cupful of tea with cognac, milk and egg, and on the second day wine with peptone. He adds bouillon with egg on the third day, and begins a " mushy " food, such as potato soup, flour soups with egg, beef tea, and minced breast of chicken, on the eighth day. After three weeks the patient may be allowed to masticate his food, and then, by means of a rubber tube, pass it into the stomach or intestine through the fistula. CHAPTER XXL HOSPITAL DIET. There are wide variations in the diets used in hos- pitals, and also in the names applied to them. In the average American hospital the classification is as follows: Ward Diet.-This is also known as "full" or "house diet." It is the ordinary diet of all patients for whom special diet orders have not been given. Light diet, also known as convalescent diet, is that used for convalescent patients generally and for others for whom it is suitable. It consists of milk, broths, eggs, and such other foods as are easily digestible yet nutri- tious. Special Diets.-Under this heading are included dietary formulas suitable for those diseases in which diet plays an important part in the treatment. It includes such diets as have been recommended in certain diseases and which bear the name of the inventor, as Tuffnell's diet for aneurism, Banting's diet for obesity, and such general diets as the following: Milk Diet.-This is composed entirely of milk, 2 to 3 quarts usually being allowed daily. Meat Diet.-This consists chiefly of nitrogenous animal foods, with a minimum of sugars and starches. It is useful in certain diseases of the stomach where there is acid fermentation. It closely resembles the diabetic diet. Farinaceous Diet.-This is made up of milk, butter, 382 383 HOSPITAL DIET. and carbohydrates. It is prescribed for convalescents and in chronic nephritis, etc. Special or extra special articles of diet, as they are often termed, include all articles not on the regular diet list for the day, and for which special orders are gen- erally given. Hospital Dietitians.-The increased study of met- abolism, especially in some hospitals, has led to the em- ployment of especially trained dietitians. The physician writes a diet prescription which is worked out by the dietitian and supplied from the kitchen. The form used at one well-known hospital is as follows: PETER BENT BRIGHAM HOSPITAL. Diet. Ward Date Name Diagnosis Feedings Calories R. Protein gm. Fats gm. Carbohydrates gm. Salts gm. Total fluid c.c. Signed A diet filling the requirements is figured out by the dietitian. It must not only be approximately correct, but be attractive from the standpoint of the person who is to consume it. CHAPTER XXII RECIPES. I/ime Water.-Into an earthen jar containing hot water stir a handful of fresh unslaked lime. Allow it to settle; then decant the clear fluid and bottle it. Water may again be added to the lime, and the mixture covered and allowed to stand to be decanted as needed. Almond Milk.-Blanch one pound of sweet and two of bitter almonds that have been soaked in cold water for twenty-four hours. This is done by pouring boiling water over the almonds, when, after a few minutes, they can easily be pressed out of their hulls. Grind the almonds in a mill or pound them in a mortar; mix with a half-pint of warm milk or water, and allow the mixture to stand two hours, after which strain through a cloth, pressing the juice out well. Thirty grams of almonds yield 200 calories of heat; 250 grams of milk yield 1700 calories.-(Wegelei) Brandy-and-egg Mixture.-Rub the yolks of two eggs with half an ounce of white sugar; add 4 ounces of cinnamon water and then 4 ounces of brandy. Dose: One or two teaspoonfuls every two hours, according to age.-{Stokes'^ Brandy-and-egg Mixture for Infants.-Beat up well the yolk of a raw egg; ten drops of brandy; one teaspoonful of cinnamon water; one coffeespoonful of white sugar.-{Louis Starri) BEVERAGES. 384 RECIPES. 385 Cold Egg-nog.-Beat up an egg; add to it two tea- spoonfuls of sugar, a glassful of milk, and a tablespoon- ful of brandy or good whisky; mix thoroughly. Hot Egg-nog.-Beat up the yolk of one egg; add a teaspoonful or two of sugar and a glassful of hot milk; strain, and add a tablespoonful of brandy or old whisky, or flavor with nutmeg or wine. Egg Broth.-Beat up an egg, and add to it half a teaspoonful of sugar and a pinch of salt; over this pour a glass of hot milk and serve immediately. Hot water, broth, soup, or tea may be used in place of milk.- {Drexel Instituted) Egg Cordial.-Beat up the white of an egg until light; add a tablespoonful of cream and beat up to- gether, then add two teaspoonfuls of sugar and a table- spoonful of brandy. Caudle.-Beat up an egg to a froth; add a wine- glassful of sherry wine, and sweeten with a teaspoonful of sugar; if desired, flavor with lemon peel. Stir this mixture into a half-pint of gruel; over this grate a little nutmeg and serve with hot toast Albumin Water.-Beat the white of one egg until very light and strain through a clean napkin. Add six ounces of water. If intended for an infant a pinch of salt may be added. A teaspoonful or more of sugar and a teaspoonful or more of lemon juice, orange juice, or sherry wine may be added to enhance its palatableness. This drink may also conveniently be made by placing all the ingredients in a lemonade-shaker, shaking until thoroughly mixed, and then straining. Serve cold. Apple Water.-Pour a cupful of boiling water over two mashed baked apples; cool, strain, and sweeten. Serve with shaved ice if desired. 386 DIETETICS FOR NURSES. Tamarind Water.-Pour a cupful of boiling water over a tablespoonful of preserved tamarinds; allow this to stand until cool, then strain, and serve with shaved ice. Currant Juice.-Take an ounce of currant juice or a tablespoonful of currant jelly. Over this pour a cupful of boiling water-use cold water with the juice-and sweeten to taste. Lemonade No. I.-Take the juice of one lemon or three tablespoonfuls of lemon juice; add from one to three tablespoonfuls of sugar and a cupful (6 ounces) of cold water. Serve with cracked or shaved ice if desired. Lemonade No. 2.-Pare the rind from one lemon, cut the lemon into slices, and place both in a pitcher with an ounce of sugar. Over this pour a pint of boiling water and let it stand until cold. Strain and serve with cracked ice.-(Pavy?) Effervescing Lemonade.-This may be made by using a carbonated water or by adding half a teaspoonful of bicarbonate of soda or potash to a glassful of either of the foregoing lemonades. Albuminized Lemonade.-Shake together a cupful of water, two teaspoonfuls of lemon juice, two teaspoon- fuls of sugar, and the white of one egg. Serve at once. Orangeade.-Cut the rind from one orange; over the rind pour a cupful of boiling water; then add the juice of the orange and a tablespoonful of sugar ; cool, strain, and serve with shaved ice if desired. If this is too sweet, a teaspoonful of lemon juice may be added. Imperial Drink.-Add a teaspoonful of cream of tartar to a pint of boiling water; into this squeeze the juice of half a lemon, or more if desired; sweeten to taste and serve cold. This drink is most useful in fevers and in nephritis. RECIPES. 387 Flaxseed Tea.-Add six tablespoonfuls of flaxseed to a quart of water; boil for half an hour; cool, strain, sweeten, and if desired flavor with a little lemon juice. Linseed Tea.-To a pint of water add two table- spoonfuls of linseed, the juice of half a lemon, ounce of bruised licorice root (or a piece of licorice the size of a filbert), and rock-candy to taste. Boil for one and one- half hours and strain.-( Yea.) Orgeat.-Blanch two ounces of sweet almonds and four bitter almond seeds.

Boil all the ingredients except the wine and sugar for ten minutes; then add the wine and sugar, strain, and serve very hot.-{Drexel Instituted) Grape Juice.-Pluck Concord grapes from the stem. Wash and heat them, stirring constantly. When the skins have been broken, pour the fruit into a jelly bag and press slightly. Measure the juice and add one- quarter the quantity of sugar. Boil the juice and sugar together and then pour into hot bottles; cork and seal with paraffin or equal parts of shoemaker's wax and resin melted together. Less sugar may be uesd.-{Drexel Instituted) Oatmeal, Barley, or Rice Water.-From the grain: Use two tablespoonfuls of grain to a quart of water. The grain should have been previously soaked overnight or at least for a few hours. When required for 388 DIETETICS FOR NURSES. an emergency, the soaking may be dispensed with and the grain boiled for five minutes instead. The water in which the grain was soaked should be poured off and fresh water added before cooking. The grain should be boiled for several hours, water being added from time to time to keep the quantity up to a quart. Strain. This makes a somewhat thin, watery gruei. From prepared flours: Various brands of prepared grain flours are on the market, such, for example, as Robinson's Barley Flour. These are all somewhat simi- lar in preparation. From two rounded teaspoonfuls to a tablespoonful of the prepared flour is added to a pint of boiling water, and this is boiled for from fifteen to thirty minutes and then strained. No previous soaking is re- quired. CEREALS AND CEREAL GRUELS. Either the grain itself or the specially prepared flour may be used. When the grains are used they should be spread on a clean table and all foreign substances re- moved. If the whole grains be used, it is well to wash them, after picking them over, with two or three changes of cold water. Cereals are best cooked in a double boiler. The lower part should be filled about one-third full of water, and, if more is added during the cooking, it should always be boiling hot. The cereal should be cooked over the fire for ten or fifteen minutes. The water should be boiled first and then salted. The cereal is added gradually and the whole stirred to prevent it from burning. It should then be placed in the double boiler and steamed until thoroughly cooked. Cereals, like other starchy foods, require thorough cooking. Most recipes allow too short a time. Oatmeal especially should be mentioned. It RECIPES. 389 develops a better flavor if cooked for three hours or more, and is better when it is prepared the day before and reheated when used. It should be just thin enough to pour when taken out of the boiler, and when cooled should form a thin jelly. Any cereal mush may be thinned with water, milk or cream and made into a gruel, or the gruel may be made directly from the grain or flour. Gruels should be thin, not too sweet nor too highly flavored, and served very hot. Milk gruels should be made in a double boiler. Gruels may be made more nutritious by the addition of whipped egg, either the white or yolk or both, and the various concentrated food products. When cereal flours are used, the flour should be rubbed to a smooth paste with a little cold water and added slowly to boiling water, stirring constantly until it is thoroughly mixed. LENGTH OF TIME TO COOK CEREALS. Cornmeal mush : Boil io minutes, then stean 1 for 3 hours or more. Oatmeal: << (C u cc cc Irish oatmeal: ll ll ll 11 ll « 8 11 11 Wheatena : ll ll << ll ll 11 11 11 Gluten mush : " 30 " Steamed rice : Steam for one hour.

Mix half a tablespoonful of arrow- root flour with a little water and add to the heated water. Boil for twenty minutes, stirring constantly; then add a cupful of milk, bring to a boil, strain, and serve hot. Barley Gruel.-Proceed as above, using a tablespoon- ful of Robinson's Barley Flour instead of arrowroot. 390 DIETETICS FOR NURSES. Oatmeal Gruel.-As above, but use oatmeal, and boil for half an hour or longer before adding the milk. Flour Gruel.-Proceed as in making arrowroot gruel, using instead a tablespoonful of wheat flour. Flavor with lemon juice, cinnamon, nutmeg or vanilla. Farina Gruel.-Proceed as in making arrowroot gruel, using instead a tablespoonful of farina, and boil but ten minutes before adding the milk. Imperial Granum Gruel.-As in the preceding, but use imperial granum instead of farina. Cracker Gruel No. i.-Use two tablespoonfuls of cracker crumbs and proceed as above. Cook only two or three minutes and do not strain. Cracker Gruel No. 2.-Brown the crackers, and reduce to a powder by means of a rolling-pin. Add three tablespoonfuls of the powdered crackers to half a cupful of milk and half a cupful of boiling water; cook for ten minutes; then add one-fourth of a teaspoonful of salt and serve.-{Drexel Instituted) Racahout des Arabes.-This is a French prepara- tion with a chocolate flavor which makes a most delicious gruel. Follow the directions given for farina gruel. Flour Ball.-Tie half a pint of flour in a square of fine cheese cloth, making a very tight ball. Place this in a pot of boiling water and cook for four or five hours. After taking out of the cloth, peel off the outside and grate the hard ball. Dry in the oven and keep in a cov- ered jar. This is useful for making gruels for diluting milk for infants. Flour-ball Gruel.-Proceed as for arrowroot gruel, using two teaspoonfuls of the above grated flour rubbed up in cold water, and stir into a pint of boiling water. Cook this for ten minutes. RECIPES. 391 Cornmeal Gruel No. i.-Use two tablespoonfuls of cornmeal and one of flour, a teaspoonful each of sugar and salt, one quart of hot water and a cupful of milk. Proceed as in making arrowroot gruel, boiling in a double boiler for three hours. Cornmeal Gruel No. a.-Take a tablespoonful of cornmeal and moisten with a little cold water. Stir this into a pint of boiling water to which a pinch of salt has been added. Cook for three hours in a double boiler, or for thirty minutes directly over the fire. In the latter case it must be stirred constantly. Gluten Gruel.-Mix a tablespoonful of gluten flour with one-fourth of a cupful of cold water and stir this into one cupful of boiling salted water. Cook directly over the fire for fifteen minutes; then add one clove and cook over boiling water for a half-hour.-{Drexel Insti- tuted) Barley or Oatmeal Jelly.-From the grain: Pre- pare the grain as directed for barley water. Use from four to six tablespoonfuls of grain to the quart of water. Boil thoroughly for several hours until the grain is thoroughly cooked. Strain and cool. The jelly when hot should be just thick enough to pour. From the prepared flours : Use two tablespoonfuls of the flour to a pint of water. Boil from fifteen to thirty minutes and strain. Partially Digested Cereals Prepared at the Table.-To a sauce of well-cooked oatmeal, wheaten grits, or rice, at the customary temperature, add one or two teaspoonfuls of Fairchild's Diastasic Essence of Pan- creas, or fifteen grains of Fairchild's Dry Extract of Pan- creas. Stir for a few minutes before eating. When the 392 DIETETICS FOR NURSES. ferments are added to very hot foods their power becomes impaired. Tapioca Jelly.-Soak a cupful of tapioca of the best quality in a pint of cold water for two hours; when soft, place in a saucepan with sugar, the rind and juice of one lemon, a pinch of salt, and another pint of water; stir the mixture until it boils ; turn into a mold and set away to cool; if desired, a glassful of wine may be added.- (Bartholow^ Tapioca Soup.-Boil a pint of meat broth or stock, and, while stirring constantly, sprinkle in ounce of pre- viously washed tapioca. Cover the saucepan, and let it stand until the tapioca is quite soft. Skim and serve.- (Yeo) Chestnut Puree.-One pound of chestnuts are peeled, and boiled in water until the second (inside) skin comes off easily. The chestnuts are placed in a sieve until all the water drains off. They are then washed in a dish and afterward pressed through a sieve. Melt three ounces of butter in a stewpan on the fire, add a little salt and sugar-enough to cover the point of a knife- and then the chestnuts. Stew them for half an hour, stirring frequently ; pour in enough bouillon so that the mush does not get too thick.-( Wegele) BREAD. Drexel Institute Bread Recipe.-For two loaves take two cupfuls of warm milk or water, two teaspoon- fuls of salt and two of sugar, a tablespoonful of lard or butter, one-half cake of compressed yeast, and about four pounds of flour. Put the water or milk, salt, sugar, and fat into a bowl. Dissolve the yeast in warm water; add it and the flour gradually; when stiff enough to handle, RECIPES. 393 turn the dough on a floured board and knead until soft and elastic. Put it back into the bowl, and let it rise in a warm place until it is double its bulk. Then divide into loaves or shape into biscuits. Allow these to rise in the pan in which they are to be baked. Cover the bread and again allow it to double its bulk. Bake loaves one hour in a hot oven. The large amount of yeast allows the bread to be made and baked in three hours. Brown Bread.-Take one-half cupful scalded milk, one-half cupful water, one teaspoonful salt, one-half tablespoonful butter, one-half tablespoonful lard, two tablespoonfuls of molasses, one-half cupful white flour, sufficient Graham flour to knead, and three-quarters of a yeast cake dissolved in one-quarter of a cupful of luke- warm water. Prepare the same as white bread. Instead of Graham flour, equal parts of Graham flour and white flour may be used in kneading. Nut-brown Bread.-The same as preceding, with one cupful of nuts chopped and added. Whole-wheat Bread.-Dissolve a quarter of a yeast cake in a tablespoonful of lukewarm water. Pour half a cupful of hot water over half a cupful of milk, and when lukewarm add the yeast and half a teaspoonful of salt. To this add a cupful of whole-wheat flour and beat for five minutes. Cover and allow this to stand in a warm place for two hours and a half. Then add whole- wheat flour gradually, mixing the mass until it can be kneaded. Knead until elastic; shape and place into baking-pans. Cover and allow to stand in a warm place until it doubles its bulk. Prick the top with a fork and bake for one hour. The oven should not be hot as for white bread. Pulled Bread.-Use bread made with water. Make into long loaves, and as soon as baked take off the crust. 394 DIETETICS FOR NURSES. Pull into stick-shaped pieces and brown slightly in a slow oven. I/axative Bread: i egg. I cup molasses. | cup dry rolled oats. i teaspoonful soda. | cup of sugar. i cup of sour milk. 3 cups of Graham flour. i tablespoonful warm water. Whip the egg and sugar together and add the molasses last; bake in slow oven for one hour. Use pulverized bran if Graham flour is not to be had. This quantity makes one loaf. Bran Biscuits: 60 gm. bran (horse bran). | teaspoonful salt. 6 gm. powdered agar-agar. 100 c.c. (I glass) cold water. Tie bran in cheese-cloth and wash under cold water tap until water is clear; heat agar-agar in the water (100 c.c.) to the point of boiling; add to washed bran the salt and agar-agar solution (hot); mold into two cakes. Place in pan on oiled paper; then, when firm and cool, bake in moderate oven thirty to forty minutes. (Allen.) VEGETABLES. TIME-TABLE FOR COOKING VEGETABLES IN WATER. (DREXEL INSTITUTE.)

RECIPES. 395 water; put the salt into the water when the vegetables are partially cooked. The water in which vegetables are cooked is called vegetable stock. Fresh green vegetables require less water than others. Cabbage, cauliflower, onions, and turnips should be cooked uncovered in a large amount of water. All vegetables must be drained as soon as tender. Season with salt and pepper and serve hot with butter or sauce. The color may be kept in green vegetables, such as spinach, by pouring cold water through them after draining. Cold vegetables may be used for salads or may be placed in a baking-dish with one-half the quantity of sauce (2 cupfuls vegetables and 1 cupful sauce), covered with buttered crumbs, and browned in a hot oven. Sauce for Vegetables 3 tablespoonfuls of butter. 3 tablespoonfuls of flour. I teaspoonful of salt. White pepper. I cupful of milk. I cupful of stock. SOUPS WITHOUT MEAT. These soups are thickened by using butter and flour; this prevents a separation of the thicker and thinner parts of the soup. The butter should be heated until it bubbles, the flour and seasoning added, and enough of the hot liquid to make a smooth sauce thin enough to pour easily; this should be poured into the rest of the hot liquid and cooked in a double boiler until the soup is of the proper consistence. In soups made of dried peas and beans soda is used to soften the casein; it is also used in tomatoes to neu- (Drexel Institute.) 396 DIETETICS FOR NURSES. tralize the acid. These soups must be served in hot dishes as soon as ready. Crisp crackers, croutons, or soup sticks may be served with them. Crisp Crackers: Split and butter thick crackers and brown in a hot oven. Cream-of-Tomato Soup: I can tomatoes. 1 cupful of flour. | teaspoonful soda. 3| teaspoonfuls of salt. | cupful of butter. | teaspoonful of white pepper. I quart of milk.

Add the oysters, which have been rinsed, and cook until the edges curl. Add seasoning, butter, and hot milk. Serve at once. This soup may be thickened with a tablespoonful of flour cooked in the butter as for white sauce. RECIPES. 397 MILK PREPARATIONS. Partially Peptonized Milk.-Into a clean granite- ware or porcelain-lined saucepan place one pint of milk, four ounces of water, and the contents of one of Fair- child's peptonizing tubes, or five grains of pancreas extract and fifteen grains of bicarbonate of soda. Heat gradually until it boils, stirring constantly. Boil gently for ten minutes, strain into a clean bottle, cork, and keep in a cool place. Before using shake the bottle well; serve hot or cold. Prepared in this way it will not become bitter. Peptonized Milk.-Cold Process.-Mix milk, water, and peptonizing agents as directed in the preceding recipe, and immediately place the bottle on ice. Use when ordinary milk is required. This is particularly suited for dyspeptics and individuals with whom milk does not, as a rule, agree. The flavor of the milk re- mains unchanged. Peptonized Milk.-Warm Process.-Put in a glass jar one pint of milk and four ounces of cold water; add five grains of extract of pancreas and fifteen grains of bicarbonate of soda. After mixing thoroughly, place the jar in water as hot as can be borne by the hand (about 115° F.). This should be heated for from six to twenty minutes. At the end of this time it may be placed upon ice until required. The contents of one of Fairchild's peptonizing tubes may be used in place of the pancreas extract. If the milk is to be kept for any length of time, it should be brought to a boil, to prevent the formation of too much peptone, which renders the milk bitter. Hot Peptonized Milk.-Mix together the usual peptonizing ingredients and add a pint of fresh cold milk; after thoroughly shaking the bottle, place it on 398 DIETETICS FOR NURSES. ice. When needed pour out the required amount, heat it, and drink it as hot as it can agreeably be taken,, If required for immediate use, the ingredients may be mixed together in a saucepan and slowly heated to the proper temperature. Effervescent Peptonized Milk.-Put some finely cracked ice in a glass; fill it half-full of Apollinaris, Vichy, or siphon water, and immediately add the pep- tonized milk. Drink while effervescing. Brandy may be added if desired. Specially Peptonized Milk.-This is to be used in the preparation of jellies, punches, and all recipes where the milk is to be mixed with fruit juices or acids. Pre- pare according to the hot process; keep the milk at a temperature of 1150 F. for one hour; pour into a sauce- pan and bring to a boil. If required hot, this may be used immediately, or it may be set aside on ice, to be used later. If not heated for an hour, the milk will curdle on being mixed with an acid. If not boiled, the pep- tonizing ferment will digest gelatin and prevent the forma- tion of jelly. Peptonized Milk Jelly.-Soak well half a box of Cox's gelatin in four ounces of water. Take one pint of hot specially peptonized milk and add four ounces of sugar. Put in the gelatin and stir until it is dissolved. Pare one fresh lemon and one orange, and add the rinds to the mixture. Squeeze the lemon and the orange juice into a glass, strain, and mix with two or three tablespoonfuls of St. Croix rum, or brandy, if preferred. Add the juices to the milk, stirring constantly. Strain, and allow it to cool to the consistence of syrup; when almost ready to set, pour into cups and set in a cold place. Do not pour the milk into molds until the RECIPES. 399 mixture is nearly ready to set, otherwise it will separate in setting. Peptonized Milk Punch..-In the usual milk punch recipes the specially peptonized milk may be used in place of ordinary milk. Take a goblet one-third full of finely crushed ice; pour on it a tablespoonful of rum and a dash of Curacao, or any other liquor agreeable to the taste. Fill the glass with peptonized milk; stir well, sweeten to taste, and grate a little nutmeg on top. Peptonized Milk lemonade.-Take a glass one third full of cracked ice; squeeze into this the juice of a lemon, and add two or three teaspoonfuls of sugar dis- solved in water. Fill the glass with fresh specially peptonized milk and stir well. If preferred, equal parts of milk and of an effervescent mineral water may be used. Pour the water on the lemon juice and ice, and immediately fill the glass with milk. Peptonized Milk Gruel.-Mix with a teaspoonful of wheat flour, arrowroot flour, or Robinson's Barley Flour with half a pint of cold water. Boil for five minutes, stirring constantly. Add one pint of cold milk and strain into a jar; add the usual peptonizing ingre- dients; place in warm water (i 15° F.)for twenty minutes, and then upon ice. Junket, or Curds and Whey.-Take a half-pint of fresh milk; add one teaspoonful of Fairchild's Essence of Pepsin and stir just sufficiently to mix. Pour into custard cups, and let it stand until firmly curdled. It may be served plain or with sugar and grated nutmeg. It may be flavored with wine, which should be added before curdling takes place. Junket with Egg.-Beat one egg to a froth, and sweeten with two teaspoonfuls of white sugar; add this 400 DIETETICS FOR NURSES. to a half-pint of warm milk; and then add one teaspoon- ful of essence of pepsin and let it stand until curdled. Cocoa Junket.-Put an even tablespoonful of any good cocoa and two teaspoonfuls of sugar into a sauce- pan ; scald with two tablespoonfuls of boiling water and rub into a smooth paste; then stir in thoroughly one-half pint of fresh, cool milk; heat this mixture until it is lukewarm-not over ioo° F.-then add one teaspoonful of Fairchild's Essence of Pepsin and stir just enough to mix; pour quickly into small cups or glasses, and let it stand until firmly curdled, when the junket is ready for use. It may be placed on ice and eaten cold; as a dessert it may be served with whipped cream.-(Fair- child^ Coflfee Junket.-Dissolve two teaspoonfuls of sugar in two tablespoonfuls of clear, strong coffee; mix this thoroughly with one-half pint of fresh, cool milk; add a teaspoonful of Fairchild's Essence of Pepsin as directed above, and serve in the same way. Vanilla, Bitter Almond, or Strawberry Junket. -Add the flavoring extract to the cold milk and then prepare in the usual way. A half a teaspoonful of vanilla or bitter-almond extract or a tablespoonful of pure con- centrated strawberry syrup should be allowed to a half- pint of milk. Milk I/emonade.-Take two ounces of sugar, five ounces of boiled milk, one-half lemon, or two ounces of white wine, five ounces of boiling water, and the rind of half a lemon. Pour the boiling water over the peel and the sugar; allow it to cool, add the milk, and then the lemon juice or wine. Strain after ten minutes. Milk Punch.-Shake together in a lemonade-shaker a glass of milk, a tablespoonful of rum, brandy, or good RECIPES. 401 old whisky, and two teaspoonfuls of sugar. After it has been poured into a glass a little nutmeg may be grated over the top. Milk Porridge.-Mix a tablespoonful of flour with one-fourth cupful of cold milk and stir into one-fourth cupful of hot milk; if desired, add two raisins cut into quarters. Cook over boiling water for one hour, and add one-quarter teaspoonful of salt just before serving. -{Drexel Institute.} Whey.-Take a half-pint of fresh milk heated luke- warm (1150 F.), add one tablespoonful of essence of pepsin, and stir just enough to mix. When this is firmly coagulated, beat up with a fork until the curd is finely divided and then strain. For flavoring purposes lemon juice or sherry wine may be added. Cream-of-tartar Whey.-Add a heaping teaspoon- ful of cream of tartar to a pint of boiling water. Strain, sweeten to taste, and serve cold.-{Pavy.} Wine Whey.-Cook together a cupful of milk and half a cupful of sherry wine. As soon as the curd separates, strain and sweeten. This may be eaten hot or cold. Lemon Whey.-This is made in the same way as the foregoing recipe, using three tablespoonfuls of lemon juice instead of the wine. Kumiss No. I.-Take a quart of skim milk, one- fifth of a cake of yeast, and two tablespoonfuls of sugar. Heat the milk. Dissolve the yeast in a little water and mix it with the sugar and lukewarm milk. Pour the mixture into strong bottles, stopper them tightly with new corks, and tie down the corks with stout twine. Shake the bottles.well and place in a refrigerator; this will allow the mixture to ferment slowly. After three 402 DIETETICS FOR NURSES. days lay the bottles on their sides, turning them occa- sionally. Five days are required to complete the fer- mentation ; the kumiss is then at its best.-{Drexel Instituted) Kumiss No. 2.-Pour into wired bottles one quart of fresh milk, half an ounce of sugar, a piece of fresh yeast cake half an inch square, and keep at a temperature be- tween 6o° and 700 F. for one week, shaking five or six times a day; then put on ice.-{Holld) Milk Mixture.-This is made of cream, two parts; milk, one part; lime water, two parts; sugar water, three parts (seventeen and three-fourths drams of milk sugar to a pint of water).-{A. V. Meigsd) Milk-and-cinnamon Drink.-Add a small amount of cinnamon to the desired quantity of milk and boil it. Sweeten with sugar and add brandy if desired.^ {Ringerd) Albuminized Milk.-Shake in a covered jar or lemonade-shaker a cupful of milk, a tablespoonful of lime water, and the white of an egg. Sweeten, flavor as de- sired, and serve at once. Milk-and-cereal Waters.-A most valuable method of preparing milk for invalids with whom it disagrees is to mix equal parts of milk and thoroughly cooked barley, rice, oatmeal or arrowroot water and boil them together for ten minutes. This may be served plain, or flavored by cooking with it a cut-up raisin, a sprig of mace, or a piece of stick cinnamon, which should be strained out before serving. Irish Moss and Milk.-Soak about two tablespoon- fuls of Irish moss for five minutes and wash thoroughly in cold water. Add to a cupful of milk and soak for half an hour; then heat slowly, stirring constantly, and RECIPES. 403 then boil for ten minutes, preferably in a double boiler; strain, and pour into cups and cool. This maybe served while hot, and may be rendered more nutritious by the addition of the white of an egg stirred into it just before serving. Milk with Other Diluents.-Milk may be diluted with advantage in many cases by adding lime water, or Vichy, Apollinaris, or some other sparking table water. From one-half to one-eighth the total volume may be added. EGGS. Eggs are exceedingly valuable as food for invalids. They should always be fresh. When received they should be washed and then placed in a cool place. They should not be kept with any article of food having an odor, as they absorb such odors and the taste is thereby impaired. Stale eggs will not sink, and if held to a bright light they show a dark spot. The yolk of an egg that has been broken may be kept fresh by placing it (unbroken) in a cupful of cold water. This should be set in a cool place. This will keep it fresh for twenty- four hours or more. Eggs and all other albuminous food should be cooked at as low temperatures as possible, in order to avoid rendering them tough. Eggs are best cooked in the shell as follows: Soft-cooked Eggs.-Place in a pint of boiling water, remove from the fire, and allow to stand for eight or ten minutes. If the egg is very cold to start with, it will take a little longer. Hard-cooked Eggs.-Place in water, bring to a boil, and then set on the back part of the stove for twenty minutes. 404 DIETETICS FOR NURSES. Eggs should be served as soon as cooked, and the dishes should be warmed and ready. EGGS AND MILK. Rules for Custards.-The eggs should be thor- oughly mixed but not beaten light, the sugar and salt added to these, and the hot milk added slowly. Custards must be cooked over moderate heat; if a custard curdles, put it in a pan of cold water and beat until smooth. Custards should always be strained.-{.Drexel Institute.') Soft Custard.-Take a pint of milk, the yolks of two eggs, two tablespoonfuls of sugar, and a pinch of salt. Mix all except the milk in a bowl. Heat the milk to the boiling-point and add, stirring constantly. As soon as mixed, pour into the saucepan in which the milk has been heated and cook from three to five minutes, stirring con- stantly until it thickens. Strain, and pour into a cold bowl, and flavor with from half to one teaspoonful of vanilla, a teaspoonful or more of sherry, or other flavoring ma- terial as desired. Custards may be cooked to advantage in a double boiler. Chocolate Custard.-Melt half an ounce of Baker's chocolate and add to the milk, and proceed as above. Steamed Custard.-Mix the above, using the whole eggs instead of the yolks. Strain, pour into cups, and steam over boiling water until firm. Baked Custard.-Proceed as above, but pour the custard into baking-cups. Place the cups in a deep baking-pan and fill the pan nearly as high as the cups with boiling water. Place in the oven and bake twenty minutes or longer, according to the size of the cup. When done a clean knife thrust into the custard comes out clean; if it is not done, it comes out covered with milk. RECIPES. 405 MEATS. General Rules for Preparing Meat.-Meat must be weighed, trimmed, and wiped with a damp cloth. It should be removed immediately from the paper in which it was wrapped and placed in a cool place. Only tender cuts of meat should be broiled, pan-broiled, or roasted. When meat is to be cooked by any of these methods, it should first be seared, and then the temperature slightly lowered; by searing, the albumin on the outer surface of the meat is hardened and the meat is thus cooked in its own juices. Tough meat should be cooked in water; boiling water hardens the albumin on the outer surface of the meat and prevents the juices from escaping. Meat should be put in boiling water and the water allowed to boil for ten or fifteen minutes; then the cooking should be allowed to proceed at a low temperature until the meat is tender. If the water bubbles, it is too hot. Cooked in this way tough meat will become tender. The time required for roasting or cooking in water varies with the weight and quality of the meat. For roasts weighing less than 8 pounds allow ten min- utes to the pound and ten minutes extra ; for those weigh- ing from 8 to 12 pounds, allow twelve minutes to the pound and twelve minutes extra; for those weighing over 12 pounds, allow fifteen minutes to the pound and fifteen minutes extra. For meat weighing less than io pounds, to be cooked in water, allow twenty minutes to the pound and twenty minutes extra. The time required for broiling meat varies with the thickness of the meat. Stock and broth are prepared by prolonged soaking of the meat in cold water and then cooking it at a low 406 DIETETICS FOR NURSES. temperature for several hours, allowing it to cool uncov- ered. The meat that remains after straining may be utilized in various ways, adding a little fresh meat to give it flavor. The fat must not be removed from stock or broth, for it excludes the air and prevents decomposition. It must, however, be entirely removed before the stock or broth is used ; this fat may be used in place of drippings. The trimmings of fat from meat should be clarified. Small globules of fat may be removed from cold broth with a cloth that has been dipped in boiling water and then wrung dry. Fat may be removed from hot broth by means of tissue-paper or a slice of bread. Cooking Tender Meats.-Roasting.-Skewer the meat into shape. Place it on a rack in a meat pan, into the bot- tom of which pieces of fat from the meat have been placed. Put in a hot oven on the grate for ten minutes, to sear the meat. If desired it may be seasoned with salt and pepper. Then remove to the floor of the oven and baste every ten minutes, until it is done. Broiling.-Remove extra fat from the meat and grease the broiler with a part of the fat. Broil over a clear fire; sear, and then turn every ten seconds. Chops one inch thick should be cooked for five minutes. A steak two inches thick should be cooked for ten minutes. Season and serve on a hot platter. Pan-broiling.-Remove all the fat from the meat. Heat a frying-pan very hot, but use no fat. Sear the meat on both sides, and then cook more slowly until it is done. Stand chops up on their edges to brown. Keep the pan free from fat. The time required for pan-broiling is the same as that required for broiling.-{Drexel Instituted) RECIPES. 407 GENERAL RULES FOR SOUPS. Both meats and vegetables should be cut into small pieces. The soup should be started with cold water poured over the meats and the heat applied gradually and the soup allowed to simmer, in order to dissolve as much of the nutriment as possible. If heated rapidly the albumin in the meat coagulates, and little but the extractives passes into the soup. The vegetables are added when the soup is nearly done. Remove the fat by skimming, by using blotting-paper by straining through a cloth wet in cold water, or, best of all, by cooling the soup when all the fat rises to the top, when it can be easily removed. Clear soups may be rendered more nutritious by the addition of sago or of some cereal, as barley or rice. These may also be added with advantage to many thick soups. Soups should always be served hot. Soup jellies are served cold, and in hot weather may be substituted for warm soups. Soups may also be made from soup stocks, which may be prepared in any quantity and kept for several days. Stocks may be made from any meat. Those made from chicken or veal are light in color, and those from beef and mutton somewhat darker. Stocks may also be made by using the bones from any kind of meats. Soup Stock.-To make stock, use a chicken or several pounds of bones with some meat attached, or a pound of lean meat and one quart of water. Cut-up vegetables may be added as desired. For flavoring add a sprig of parsley and of celery, a peppercorn, a small onion, and a scant teaspoonful of salt. Any of the flavoring vegetables may be omitted as desired or others 408 DIETETICS FOR NURSES. added. The meat should simmer for several hours, until but half the quantity of water remains. Then add the other ingredients, simmer half an hour longer, strain and cool. Remove the fat. Soup Stock from Beef Extract.-Cook the other in- gredients, except the salt, as given above, for half an hour, using a quart of water. Then add a teaspoonful oi beef extract and a quarter of a teaspoonful of salt. Soup from Stock.-Rice, tapioca, or whatever is de- sired is cooked and the stock added, with additional seasoning as thought necessary. Cream, yolks of eggs, Irish moss, cornstarch or arrowroot may be added to render the soup more nutritious. Chicken Broth.-Take one pound of chicken and a pint of cold water. Clean the fowl, cut it into pieces, and remove the skin. Separate the meat from the bone and chop the meat very fine. Place with the bones-if large, they should be broken-in the water and soak for an hour. Cook over hot water for four or five hours at a temperature of 190° F. Strain and add salt. Water must be added from time to time to keep the quantity up to a pint. Remove the fat. If the broth is to be reheated use a double boiler. Sweetbread Soup.-The sweetbread is soaked in cold water for one hour, the water being renewed fre- quently during this time. It is then boiled for one hour in slightly salted water or beef broth, to which one may add one teaspoonful of julienne to improve the taste. After it is soft the sweetbread is taken out of the beef broth and all blood-vessels and skin are removed. It may now be cut into pieces the size of a walnut and put on a plate, over which the beef broth is poured, or the sweetbread may be forced through a sieve, beef RECIPES. 409 broth poured over this, and the whole put on the fire again until it boils, after which the soup may be served. This latter process is to be recommended in the case of dyspeptics. One hundred grams of raw sweetbread generate about 90 calories of heat.-{Wegeled) Meat Broth (Beef, Veal, Mutton, or Chicken).- Cover one pound of chopped lean meat with one pint of water and allow it to stand for from four to six hours. Then cook over a slow fire for an hour until reduced to half the quantity. Cool, skim, pour into jar and strain. Veal Broth.-Pour a pint of water on a half-pound of finely chopped lean veal and allow it to stand for three hours. Boil for a few minutes, strain, and season with salt. Clam or Oyster Juice.-Cut the clams or oysters into pieces and heat for a few minutes in their juice. Strain through muslin and serve while hot. In straining great care must be taken that sand does not pass through the muslin. The juices should be diluted and may be frozen.-{Drexel Instituted) Clam Broth.-Wash three large clams very thor- oughly, using a brush for the purpose. Place in a kettle with half a cupful of cold water. Heat over the fire; as soon as the shells open the broth is done. Strain through muslin, season, and serve.-{Drexel Instituted) Mutton Broth with Vegetables.-Allow one pound of neck of mutton to each pint of water; add carrots, turnips, onions, and barley; let all simmer together for three hours. Mutton Broth without Meat.-Cook two "shank- ends" in a pint of cold water, and vegetables as directed in the foregoing recipe; simmer for three hours and strain. 410 DIETETICS FOR NURSES. Beef Tea No. I.-Cut up a pound of lean beef into pieces the size of dice; put it into a covered jar with two pints of cold water and a pinch of salt. Let it warm gradually and simmer for two hours, care being taken that it does not at any time reach the boiling- point.-(Yeo^ Beef Tea No. a.-Put a pound of finely mixed beef with a pint of cold water into a suitable vessel. Let it stand for an hour, stirring occasionally. Put the vessel containing the beef into a saucepan of water, place it over the fire, and allow the water to boil gently for an hour (or the vessel containing the beef tea may be put into an ordinary oven for an hour). Pass the beef tea through a strainer. A fine sediment appears in the fluid, and this should be drunk with the liquid. Flavor with salt. At no time should the beef extract be exposed to a temperature of more than 1700 F.-{Pavy^ Beef Tea No. 3.-Chop fine a pound of beef free from fat, tendons, etc., and digest with a pint of cold water for two hours. Let it simmer on the stove for three hours at a temperature never above 1600 F. Re- place the water lost by evaporation by adding cold water, so that a pint of beef tea shall represent a pound of beef. Strain and carefully express all fluid from the beef.- {Bartholow^ Beef Tea with Oatmeal.-Mix thoroughly one tablespoonful of groats with two of cold water; add to this a pint of boiling beef tea. Boil for ten minutes, stirring constantly, and strain through a coarse sieve.- (Yeo) Beef Tea, Flavored.-Beef tea may be flavored agreeably by boiling in it a pinch of mixed herbs, a bay- leaf, or a bit of onion, carrot, turnip, or celery and a few RECIPES. 411 peppercorns. The roots should either be chopped small or be scraped to a pulp before being added to the broth. -(Yeo) Beef Juice.-Broil quickly pieces of the round or sirloin of a size to fit the opening in a lemon squeezer. Both sides of the beef should be scorched quickly to prevent the escape of the juices, but the interior should not be fully cooked. As soon as they are ready the pieces of meat should be squeezed in a lemon squeezer previously heated by being dipped in hot water. As it drips the juice should be received into a hot wineglass; it should be seasoned to the taste with salt and a little Cayenne pepper, and taken while hot.-(Bartholow) Cold Beef Juice.-Cover one pound of finely chopped lean beef with eight ounces of cold water and allow it to stand for eight or ten hours. Squeeze out the juice by means of a muslin bag; season with salt or sherry wine and drink cold or slightly warmed. It may be added to milk, care being taken that the milk be not too hot before the juice is added. Iced Meat Extract.-Cut into pieces the size of a hand one kilo of fresh beef; wrap in a coarse, lattice- like linen bag, put under a lever press, and press slowly. The juice should be caught in a porcelain dish. This is done best by a druggist. By this method about 500 gm. of juice are obtained. The juice is mixed with 250 gm. of sugar, 200 gm. of freshly expressed lemon juice (this last is best omitted in the case of dyspeptics), and 20 gm. of cognac containing vanilla extract; stir in well the yolks of three eggs ; the entire mixture is then placed in a freezer.-(7/. Ziemssen) Raw-meat Juice.-Add to finely minced rump steak cold water, in the proportion of one part of water to four 412 DIETETICS FOR NURSES. parts of meat. Stir well together, and allow it to stand for half an hour. Forcibly express the juice through muslin, twisting it to get the best results.-(Cheadle^ Succus Camis (Meat Juice).-Cut up the meat into small bits, arrange in layers separated from one another by coarse linen, and then place in a powerful press. From each kilogram of meat about 230 gm. of a blood-red juice are obtained. This contains about 6 per cent, of albuminates. Its taste is similar to that of raw meat; its flavor may be improved by the addition of salt and beef tea not hot enough to coagulate the albumin.- {Pettenkoffer and Pod.) Beef Essence.-Chop up very fine a pound of lean beef free from fat and skin ; add a little salt, and put into an earthen jar with a lid; fasten up the edges with a thick paste, such as is used for roasting venison in, and place the jar in the oven for three or four hours. Strain through a coarse sieve, and give the patient two or three table- spoonfuls at a time.-(Fu) American Bouillon (American Broth).-Place in a tin vessel that can be sealed hermetically alternate layers of finely minced meat and vegetables. Seal it, and keep it heated in a water bath (bain marie) for six or seven hours, and then express the broth.-(Yeo.) Bottle Bouillon.-Cut beef, free from fat, into squares. Place these in a stoppered bottle, put the bottle in a basin of warm water, heat slowly, and boil for twenty minutes. There will be about an ounce of yellowish or brownish fluid for each three-quarters of a pound of meat used. The flavor is that of concentrated bouillon.-( Uffelmamd) Peptonized Oysters.-To half a dozen oysters with their juice add half a pint of water and boil for a few RECIPES. 413 minutes. Pour off the broth and set it aside. Mince the oysters, and with the aid of a potato-masher reduce to the consistence of a paste. Place this with the broth in a glass jar and add fifteen grains each of extract of pan- creas and of bicarbonate of soda and mix. Allow this to stand in hot water (1150 F.) for one and one-half hours. Pour into a saucepan and add half a pint of milk; heat over a slow fire to boiling-point. Flavor with salt and pepper and serve hot. Let the heating be done gradually, and be careful to bring the mixture to a boil before taking it from the fire.-{Fairchild)) Peptonized Beef.-Cover one-fourth of a pound of finely minced lean beef (or beef and chicken mixed) with half a pint of cold water. Cook over a slow fire until it has boiled for a few minutes, stirring constantly. Pour off the broth and rub or pound the meat to a paste. Put meat and broth and half a pint of cold water in a glass jar, and add twenty grains of extract of pancreas and fifteen grains of bicarbonate of soda. Mix well and keep in a warm place-at about 1 io°-i 150 F.-or place it in warm water and allow it to stand three hours, stir- ring or shaking occasionally. Boil quickly; strain or clarify with the white of an egg and season with salt and pepper. If desired, it need not be strained, as the small particles of meat are usually easily digested. Cereals may be added, boiling with half the amount of water previously directed, and mixing all together before pep- tonizing. At the end of three hours the mixture must be boiled or it will spoil.-{Fairchild)) METHODS OF PREPARING RAW BEEF. Meat given raw should always be perfectly fresh and very finely divided. Scrape the meat with a sharp knife, 414 DIETETICS FOR NURSES. which will separate the coarser fibers. If the resulting mass is stringy, pass through a fine sieve. This may be seasoned with salt and pepper, and served on toast, crackers, or bread and butter. It may be rolled into small balls and swallowed. These may be flavored as desired. They may also be slightly browned by rolling about rapidly in a hot saucepan, care being taken not to change any but the outside of the ball, and that but slightly. Scraped beef may be served as a liquid or semi-solid food. Mix it with an equal quantity of cold water until it is quite smooth. Place in a double boiler and cook until thoroughly heated, stirring constantly. Add a little salt and pepper and serve at once. This may be made thicker by adding less water. Raw Meat with Milk and Sugar.-Scrape half a pound of rump steak with a knife until all the pulp is removed; sweeten with sugar, breaking the lumps of sugar with the meat in a basin with a small wooden spoon. Add slowly as much milk as will make it about the thickness of arrowroot; flavor with brandy. If any fiber of the meat remains, strain through a gravy strainer. The mixture should be perfectly smooth.-(Ringeri) Raw-beef Soup.-This is made by chopping up one pound of raw beef and placing it in a bottle with one pint of water and five drops of strong hydrochloric acid. This mixture is allowed to stand on the ice over- night, and in the morning the bottle is placed in a pan of water at I io° F., and kept at about this temperature for two hours. It is then placed in a stout cloth and strained until the mass that remains is almost dry. The filtrate is given in three portions daily. If the taste of the raw meat is objectionable, the meat may quickly be roasted on one side and the process completed in the manner previously described.-(Weir Mitchelli) RECIPES. 415 PANOPEPTON. Iced Panopepton.-To a small glass half full of clean crushed ice add one tablespoonful of Panopepton; let this stand for a minute and then sip slowly. Panopepton Jelly.-This is made of one ounce of fresh celery cut into small pieces, one-half of a small box of the best gelatin, one-fourth of a teaspoonful of salt, two dashes of pepper, six tablespoonfuls of Panopepton, and two cupfuls of cold water. Soak the gelatin in half a cupful of cold water for one hour; put the water and celery in a double boiler on the fire and simmer for one- half hour; add the salt, pepper, and soaked gelatin and stir until it is dissolved; remove from the fire and add the Panopepton ; stir and strain through linen into a jelly bag and set near ice. Serve in small quantities. Panopepton Jelly with Orange.-The articles required are one-half of a small box of the best gelatin, one tablespoonful of sugar, six tablespoonfuls of Pano- pepton, the juice and rind of one orange, and one pint of cold water. Put the gelatin, orange peel (cut in small pieces), orange juice, and cold water in a dish and let it stand for one hour, then put in a double boiler over the fire, add the sugar, and stir until it is dissolved; now strain through linen, add the Panopepton, and stir well. Pour into a jelly jar and set near the ice. Serve in small quantities. Panopepton Hot.-To a small teacup two-thirds full of boiling water add one tablespoonful of Panopep- ton and one teaspoonful of fresh lemon juice; a little sugar may be added if desired. Stir and drink immedi- ately, sipping slowly. Panopepton Bouillon Hot.-Put one tablespoon- ful of Panopepton in a small teacup; fill the cup nearly 416 DIETETICS FOR NURSES. full of boiling water, and flavor to taste with celery salt or plain salt and pepper; stir and sip slowly. Panopepton Cordial.-Put into a cordial glass or any small glass two teaspoonfuls of clean crushed ice; add one teaspoonful of Fairchild's Essence of Pepsin and three teaspoonfuls of Panopepton. Sip slowly. This is a good after-dinner cordial for those who suffer discom- fort after eating. Panopepton with Whey.-Put into a small teacup one or two teaspoonfuls of clean crushed ice; add one tablespoonful of Panopepton, stir, and then fill the cup with whey. Drink slowly. Egg Gruel.-Take one cupful of hot beef broth made with " Soluble Beef," one egg, and one-half tea- spoonful of salt. Beat the white and the yolk of the egg separately; add the hot beef broth gradually to the yolk, stirring continually. Whip the white to a stiff, dry froth with the salt, and beat it into the hot broth. Return to the double boiler and reheat. Serve very hot. Barley Gruel with Beef Extract.-One-half tea- spoonful of " Soluble Beef," two cupfuls of hot water, one tablespoonful of barley flour, one saltspoonful of salt. Dissolve the beef in the hot water, and mix the flour and salt together with a little cold water. Pour the boiling stock on the flour and cook for ten minutes. Strain and serve very hot. Beef Broth with Poached Egg.-Prepare the broth in the proportion of half a teaspoonful of " Solu- ble Beef" to one cupful of hot water and add a poached egg- A Nutritive Drink for Delicate Women and Children.-This is made by mixing one-fourth to one- half teaspoonful of " Soluble Beef," five ounces of boil- RECIPES. 417 ing water, and one-half ounce of cream; season with salt and pepper to suit the taste. Beef Broth with Grain.-Take one teaspoonful of " Soluble Beef," one quart of water, one tablespoonful of rice, and salt to taste. Dissolve the "Soluble Beef" in the hot water, and add the well-washed rice. Simmer slowly until dissolved and absorbed by the rice, adding more beef broth if too much boils away. If not entirely dissolved, the broth should be strained before using. Beef-tea Egg-nog.-This requires one-eighth tea- spoonful of " Soluble Beef," one-half cupful of hot water, one tablespoonful of brandy, and a pinch of salt. Beat the egg slightly, and add the salt and sugar. Dissolve the " Soluble Beef" in the hot water, add to the egg, and strain. Mix thoroughly, adding wine, and serve. MEAT JELLIES WITHOUT GELATIN. Chicken Jelly.-Half a grown chicken should be well pounded, and boiled in one quart of water for two hours until only a pint remains; season and strain. Serve hot or place on ice, where it will " jel." Veal-bone Jelly.-Place ten pounds of veal bones and ten quarts of water or weak bouillon over the fire and bring to just a boil. Skim and add two pounds of barley and a little salt. Simmer for five or six hours and then strain. If too thick, dilute, before serving, with bouillon. Stir in the yolk of an egg in a cup and serve. Meat Jelly.-This is made by cooking good bone- less, lean beef on a water bath with a little water for sixteen hours or until it becomes gelatinized. Of the artificial preparations on the market for making bouillon, the most reliable is Liebig's Extract of Meat (io : 250 (gm. or Cibil's Bouillon (1 teaspoonful to 25o gm.). 418 DIETETICS FOR NURSES. Inaglio's bouillon capsules are also very convenient. If it is desired to make the bouillon more nutritious, one teaspoonful of meat peptone may be added.-{Hepp^ Jelly for Dyspeptics.-Remove the skin and meat from one calf's foot; wash the bones and place in cold water on the stove; when it begins to foam, skim off the refuse which gathers on top. After rinsing off the scum with cold water, put the bones into a pot with one-quarter kilo of beef or half an old hen, one-quarter liter of water, and 5 gm. of salt, and boil slowly for from four to five hours. Pour the jelly thus formed through a fine sieve, and place overnight in a cellar. Next morning remove the fat, and clarify the cold jelly by adding one egg with its shell mashed, beating and stirring steadily. Then, with the addition of a little cornstarch, subject the whole to a temperature not over 6o° R., or the white of the egg will curdle. Constantly beat and stir. If the jelly begins to get grainy, cover and let it cool until the white of the egg becomes flaky and separates. Then strain again several times until it becomes perfectly clear; add 5 gm. of extract of meat, pour the jelly into a mold, and let it cool again. The gravy from a roast maybe utilized and is very palatable. It must be stirred in while the mass is still warm and liquid. This jelly is usually relished with cold fowl, but spoils easily in summer; it must there- fore be kept on ice.-(Weil^ Dishes Made with Gelatin.-Gelatin should be soaked in cold water for about half an hour to soften it. It may then be easily dissolved by adding boiling water. If it is desired to soften gelatin quickly, it should be placed in cold water and gradually heated over boiling water until it dissolves. If a jelly is to be strained, a wet cloth should be used for the purpose. Jelly molds should be wet with RECIPES. 419 cold water before being filled. When granulated gelatin is used, much smaller amounts are required than when the ordinary form is used. Wine Jelly.-Soak a teaspoonful of granulated gela- tin in two tablespoonfuls of cold water and half a cupful of hot water. Add two tablespoonfuls of sugar and half a teaspoonful of lemon juice, and when cooling add two tablespoonfuls of wine.-{Drexel Instituted) Lemon jelly is made in the same manner as the wine jelly just described, using a tablespoonful of lemon juice in place of the quantity directed. Orange jelly is made in a similar manner, using two teaspoonfuls of lemon juice, four tablespoonfuls of orange juice, and three tablespoonfuls of sugar, but a little less of the boiling water. Coffee jelly is also made similarly, adding an ounce or two of coffee. Milk Jelly.-Take two quarts of milk and add half a pound of sugar. Boil for five or ten minutes. Cool, and add an ounce of gelatin dissolved in a cupful of cold water. Flavor with the juice of two or three lemons and three glasses of good Bordeaux wine.-{Schlesingerd) Irish-moss Blanc-mange.-Wash a tablespoonful of Irish moss in several changes of water and pick it over carefully. Place it in a double boiler together with half a cupful of milk. Cook until it thickens when dropped on a cold plate. Add salt, strain, and flavor. Pour into a custard cup that has first been rinsed in cold water.- {Drexel Instituted) Meat Jellies with Gelatin.-Use any kind of meat broth desired, but always one with an appetizing flavor. Add a teaspoonful of granulated gelatin to enough broth to cover it, and allow the gelatin to soak for a few 420 DIETETICS FOR NURSES. minutes. Then add the remainder of a cupful of the broth very hot and stir until the gelatin is dissolved. Strain, and pour into molds to cool. Meat Jellies with Tapioca.-Mix a cupful of broth as above with four level tablespoonfuls of pow- dered tapioca. Heat until quite clear, stirring con- stantly. Add salt and season as desired. Pour into molds and cool. Meat Jellies with Irish Moss.-Wash two table- spoonfuls of Irish moss thoroughly. Add this to a cup- ful of hot broth and allow it to stand for half an hour ; then heat slowly, stirring constantly, and boil for ten minutes, preferably in a double boiler. Strain, and pour into molds and cool. Albuminized Jelly.-Any of the above meat jellies may be rendered more nutritious by the addition of the white of an egg. The egg should be well beaten and stirred into the jelly just after it has been taken off the fire. RECIPES FOR FOODS FOR DIABETICS. Camplin's Bran Cakes.-Take a sufficient quan- tity-say a quart-of wheat bran, boil it in two succes- sive waters for a quarter of an hour, each time straining it through a sieve ; then wash it well with cold water (on the sieve) until the water runs off perfectly clear; squeeze the bran through a cloth as dry as possible, and then spread it thinly on a dish; place it in a slow oven; if put in at night, let it remain until the morning, when, if perfectly dry and crisp, it will be ready for grinding. The bran thus prepared must be ground in a mill, and sifted through a wire sieve that has so fine a mesh that a brush must be used to pass it through ; that which RECIPES. 421 remains in the sieve must be reground until it becomes quite soft and fine. Take of this bran powder three ounces (some patients use four ounces); the other in- gredients are as follows: three new-laid eggs; one and one-half or, if desired, two ounces of butter; about half a pint of milk. Mix the eggs with a little of the milk, and warm the butter with the remainder; then stir the whole well together, adding a little nutmeg or ginger or any other agreeable spice. Bake in small tins (patty pans), which must be well buttered, in a somewhat quick oven for about half an hour. When baked, the cakes should be a little thicker than a captain's biscuit; they may be eaten with meat or cheese for breakfast, dinner, or supper. At tea they require a somewhat liberal allow- ance of butter, or they may be eaten with curd or with any soft cheese. It is important that the flour be pre- pared as directed above. If the cakes do not keep well or if they have not been well prepared, place them before the fire for ten minutes every day. Almond Pudding.-Take two eggs, one-quarter of a pound of almond flour, one-quarter of a pound of but- ter, and three tabloids of saccharin dissolved in a table- spoonful of brandy. Warm the butter, beat in the almond flour and the yolks of the eggs, and add the dis- solved saccharin. Whip the whites into a stiff froth, and beat all together. Put into dariole molds and bake in a quick oven; serve with a little hot sauce made with dry sherry and saccharin.-(Mrs. Hart?) Almond Biscuit.-To each ounce of almond flour add the whites of two eggs and salt to taste. Whip the whites to a stiff froth, add the almond flour, and beat well together. Put in buttered patty pans and bake in a moderately quick oven for from fifteen to twenty min- 422 DIETETICS FOR NURSES. utes. The whole must be done quickly, and baked as soon as the ingredients are mixed. This biscuit is a use- ful substitute for bread.-(Mrs. Hart^) Almond Cakes No. I.-Take one pound of ground almonds, four eggs, two tablespoonfuls of milk, a pinch of salt. Beat up the eggs, and stir in the almond flour; place in twelve flat tins and bake in a moderate oven for about fifteen minutes.-(Saundby.) Almond Cakes No. 2.-Break up about one-quar- ter of a pound of sweet almonds in a stone mortar (or almond flour may be used). Put the flour into a linen bag, which should then be immersed for one-quarter of an hour in boiling water, acidulated with a little vinegar to remove the small amount of sugar from the almonds. Mix well with three ounces of butter and two eggs. Then the yolks of three eggs and a little salt are added, and the whole stirred briskly for some time. Beat the whites of three eggs to a fine froth and add to the mixt- ure. The paste is then made into biscuits, smeared with butter, and baked with a gentle fire.-(Seegend) Aleuronat Bread.-Take about six or seven ounces of ordinary wheat flour and the same quantity of aleu- ronat powder; five ounces of the best butter; one tea- spoonful of salt; three-quarters of an ounce of baking- powder. The flour and the aleuronat are mixed in a warm dish, and the melted butter and milk (made luke- warm) are added gradually, followed by the salt, and finally by the baking-powder (one part of sodium carbon- ate and two parts of cream of tartar). The dough is well mixed, then molded into two loaves, and baked at a good heat.-(Eb string Aleuronat and Almond Cakes.-Three ounces of aleuronat; three ounces of almond flour; beat up one RECIPES. 423 egg, and add about two teaspoonfuls of cream and a little water. Moisten the aleuronat with a little water containing saccharin and let it stand for a few minutes; then add the almond flour, the egg, the cream, and the water just as required to make a light paste. Spread on a tin. Cut into squares, and bake in a moderate oven for twenty minutes.-{Williamson^) Aleuronat Pancakes.-Take one egg and beat it up in a little water and cream; take two teaspoonfuls of aleuronat powder and half a teaspoonful of baking-pow- der and a little salt. Mix well, and then add gradually to the egg and cream and beat into a batter; allow it to stand for five minutes. If it is too thick, add a little more cream and water. Fry in an ordinary frying-pan greased with a little lard. At the end of about eight minutes, when the under surface is browned, turn it over and continue to bake it for five minutes longer.-(Wil- liams oni) Aleuronat and Suet Pudding.-This is a palatable and cheap dish. To make it take two ounces of aleuro- nat flour and two ounces of suet, one egg, a pinch of salt, and half a teaspoonful of baking-powder. Sprinkle a little aleuronat flour on a chopping-board and chop the suet on this part of the board. Then mix the remaining aleuronat with the suet in a dishpan. Add the salt and the baking-powder. Beat up the egg in about three tablespoonfuls of water to which a little saccharin has been added. Add the egg gradually to this mixture, rubbing the whole mass well into a paste. It may be necessary to add a little more water. Drop into a tin pudding mold smeared with butter or lard, float it in a pan of water, and boil for two hours, taking care that the boiling water does not get into the mold ; or, better still, 424 DIETETICS FOR NURSES. the pudding may be baked in the oven. Its taste is im- proved by the addition of half an ounce of almonds. A small quantity of red wine may serve as a sauce.-(Wil- liamson.) Cocoanttt Pancakes.-Beat up one egg in two table- spoonfuls of milk, or, better, in a little cream and water, and add a pinch of salt. Then add two tablespoonfuls of cocoanut powder (freed from sugar). Allow this to stand for from five to ten minutes. Add a little more cream and water. Mix well until it is a little thicker than ordinary pancake batter. Put a little lard in the frying- pan and heat until the lard is just melted; then drop in half of the mixture. Allow this to remain over a mod- erate fire for a few minutes-about five-until the under surface is brown; then turn the cake over and heat for another five minutes. The other half of the mixture may be used for the second pancake.-(Williamsonl) Cocoanut Cakes.-Mix three tablespoonfuls of cocoanut powder into a paste with a little German yeast and water. The mixture should be allowed to remain by the fire or in a warm place for about twenty minutes, or until fermentation occurs and it becomes " puffy." Then add a small quantity of a watery solution of sac- charin. Beat up one egg, and add this with two tea- spoonfuls of cream and a little water to the cocoanut paste. The whole should be well mixed, dropped into small tins, and baked in an oven for about thirty min- utes.-(Williamsonl) Cocoanut and Almond Cakes.-To make these, the following ingredients are required: Three-quarters of a pound of the finest cocoanut powder, one-quarter of a pound of ground almonds, six eggs, and half a cupful of milk. Beat up the eggs and stir in the cocoa- RECIPES. 425 nut and almond flour. Divide into sixteen flat tins, and bake for twenty-five minutes in a moderate oven.- (Saundbyi) Cocoanut Pudding'.-Take three tablespoonfuls of cocoanut powder, mix with a little water and German yeast, and keep for twenty minutes in a warm place, so as to allow the small quantity of sugar present to decom- pose ; add four tablespoonfuls of cream, one egg, a little salt, and half a pint of water sweetened with saccharin. Mix into a paste. Place in a dish greased with butter. Cook like rice pudding, in a slow oven for thirty min- utes.-( Williamson^) ISight Custard.-Beat up well one egg; make a mixture of cream and water and boil; gradually add the boiled cream and water, while hot, to the egg, stirring with a spoon. Then place the mixture in a pan over the fire, and stir constantly until it becomes thick; then pour into a glass. It is important that the mixture should not be heated too much-i. e., that it be not boiled-as the albumin would be coagulated. Flavor with cinna- mon and sweeten with saxin or saccharin if desired. Cheese Cakes.-Take one pint of milk, half a table- spoonful of rennet, one ounce of butter, two eggs, one tablespoonful of brandy, one-quarter of an ounce of almonds, and a little saccharin. Curdle the milk, and let it stand in a warm place until thoroughly set; tie a piece of muslin over a bowl and pour the milk over the muslin; let it stand until all the whey has been strained off. Beat the curd smooth, and add the butter and egg, well beaten, with the brandy, almonds, and saccharin. When well mixed pour into pattypans and bake for fifteen or twenty minutes.-(Mrs. Hartl) Stewed I/ettuce.-A well-grown head of lettuce should be selected. Boil this in plenty of water, taking 426 DIETETICS FOR NURSES. care not to let it fall to pieces. When nearly done take it out of the water, drain, and place in a stewpan with a little rich brown gravy and allow it to simmer for twenty minutes. Inulin Biscuit.-Put 50 gm. (i| oz.) of inulin in a large porcelain basin, place this over a hot-water bath, and with 30 c.c. (1 oz.) of milk and as much hot water as may be necessary, rub up into a smooth dough, into which the yolks of four eggs and a little salt have been mixed. To this add the whites of the four eggs, having first beaten them to a foam, and working them in care- fully. Bake in tin molds smeared with butter. The taste of the biscuit may be improved by adding vanilla or other flavoring extract. Inulin is too expensive to be used by the average patient. Peanut Flour.-This contains about 25 per cent, of carbohydrates. The peanut kernels should be boiled in water for half an hour to extract a portion of the oil which they contain. They should then be dried, and rolled into fine particles with a rolling-pin. Place the kernels in boiling water acidulated with tartaric acid or vinegar, in order (1) to extract saccharin elements; (2) overcome the taste and odor of the peanut; (3) to prevent emulsification of the remaining oil. When they have been thoroughly boiled in acidulated water, the ground kernels should be subjected to dry heat and then rolled into a fine flour. This flour may be made into a form of porridge with milk; bread and biscuits may also be baked from it; and it may be made into the form of a German pancake.-{Stern^ Home-made Substitute for Bread.-Beat up thor- oughly six eggs; add a teaspoonful of baking-powder or its chemical equivalent, and one-quarter of a teaspoon- ful of salt, and beat again. Pour this mixture into hot RECIPES. 427 waffle-irons smeared with butter, and bake in a very hot oven. By way of variety almonds (powdered) may be added. These biscuits may be eaten hot with butter and cheese. Sugar-free Milk for Diabetic Feeding.-Take I liter of skim milk, heat to a temperature of 300 C., and add 10 c.c. of glacial acetic acid, diluted with 100 c.c. of water. Mix, and allow the mixture to stand for about fifteen minutes. Collect the separated casein, and let it drain on very fine muslin, using no pressure. Remove the casein to a mortar, rub into a smooth paste, add | liter of distilled water, and strain as before. Repeat this washing of the casein twice. Transfer to a mortar, rub until quite smooth, and add 2| gm. of potassium hydrate dissolved in 100 c.c. of water (or as much of the potassium hydrate as is necessary to make the product just alkaline to phenolphthalein). Add 100 gm. of ordinary Devonshire clotted cream, 5 gm. of gelatin, previously dissolved, 0.06 gm. (1 gr.) of saccharin, and water, at about 38° C., up to 1 liter. Lastly, strain through fine muslin.-{Hutchison^ Soy Bean Cookery.1-In diabetes the beans may be added to the diet simply to give variety, and they may also be used to great advantage in connection with an otherwise carbohydrate-free diet, particularly in those cases in which the sugar percentage is high, and it is with these cases we have had particular success. The simplest way to use the beans is to cook them like the ordinary navy bean, preparing either bean soup, boiled beans, or baked beans, the flavor usually being rather improved by the addition of a piece of fat salt meat. It is also a good plan to soak the beans for eight or ten hours, stir them up, and remove the rather firm envelope 1Ruhrah, Medical Record, Sept. 23, 1911. 428 DIETETICS FOR NURSES. which encloses them, most of which will be found to come to the surface, from which they may be easily skimmed off The beans may be boiled and reduced to a smooth gruel and used in this way as a gruel, although this is rather a troublesome process; or the beans may be thoroughly boiled and mashed and may be flavored with some other vegetable, particularly stewed tomatoes. The soy bean flour may be utilized in many ways. Gruels.-A quart of gruel is made by boiling from 1 level tablespoonful to 6 ounces of the soy flour (made by the Cereo Company, Tappan, N. Y.) in 1 quart of water for fifteen minutes, adding water to make up for the loss of evaporation. Salt should be added to taste. Protein. Fat. Carbohydrates. I level tablespoonful to quart . . . • 0-35 O.I5 0.08 I ounce 4 (tablespoonfuls) to quart . . I.40 0.60 O.3O These gruels do not thicken during cooking, as they con- tain no starch, and readily settle on standing. This may be overcome by adding I to 2 heaping teaspoonfuls of barley, oat, or wheat gruel flour before cooking, which will add 0.6 to 1.2 per cent, starch to the gruels, and also slightly increase the percentage of protein. Broths.-Add 1 to 8 ounces of the flour to 1 quart of beef, mutton, veal, or chicken broth and boil for fifteen minutes, adding water to make up for loss of evaporation; or, boil the same quantity of the soy flour for one hour with 1 quart of water, to which has been added a piece of ham, bacon, or salt pork to give flavor. Each ounce of the flour will add to the broth about 13 grams of protein and 120 calories, or in percentage add 1.4 per cent, protein, 0.6 per cent, fat, and 0.30 per cent, carbohydrates. A broth made with 6 ounces of the soy flour to the quart would be half as rich in protein and fat as steak. RECIPES. 429 Muffins.-To make muffins from the soy flour, take i| teacupfuls of the soy flour, | teacupful of wheat flour, j teaspoonful of salt, 2 eggs, 1 teacupful of sweet milk, 2 rounded teaspoonfuls of baking powder, and i| table- spoonfuls of melted, but not hot, butter. Beat well to gether, adding the melted butter last, and bake in gem pans in a hot oven. This will make about 12 muffins which contain about 150 grams of protein, and which will yield about 1800 calories, of which the carbohydrates produce but 280. Inasmuch as the soy flour contains no starch, the addition of some wheat flour in making muffins is required. The mixture of wheat and soy flour in this formula will contain about 36 per cent, protein and 20 per cent, carbohydrates, against 14 per cent, protein and 60 to 70 per cent, carbohydrates in gluten flour. The pro- portion of protein to carbohydrates is eight to ten times as large in the mixed soy and wheat flour as in the gluten flour. In addition to these methods, the following recipe for muffins has been suggested by Dr. Skinner, of New Haven, Conn.: Soy bean flour, ij cupfuls; salt, | tea- spoonful ; baking powder, 2 even teaspoonfuls. Mix well and add 2 tablespoonfuls of cream which has first been thoroughly stirred into a cup of cold water. Add 2 eggs and beat together. Then add 2 tablespoonfuls of melted butter and beat the whole mixture well together. Bake fifteen minutes in a heated gem pan. The above makes 15 muffins. Another recipe for muffins is to beat up 3 eggs, add 1 cup of milk in which 1 grain of saccharin has been dis- solved, and a lump of butter the size of an egg. Enough of the bean flour should be added to make a batter with | teaspoonful of baking powder. This should be baked in buttered muffin pans. 430 DIETETICS FOR NURSES. Nut-cakes.-These may be made by using the above muffin recipe as a basis and adding chopped nuts, al- monds, or any other kind desired; and the flour is im- proved by the addition of a small amount of spice. Soy Bean Cakes.-These may be made by taking I tablespoonful of cocoa, i teaspoonful of cinnamon, I tea- spoonful of allspice, and chopped nuts, adding them to the batter as prepared for the muffins. Breakfast Food.-As a breakfast food it may be util- ized by taking I cup of flour, enough milk or water to moisten it into a paste, a pinch of salt, and I grain of saccharin, which should be dissolved before adding. Boil one and a half hours in a double boiler and serve with rich cream. Pancakes.-These may be made by beating up 2 eggs with a pinch of salt, adding enough meal to make a batter, and | teaspoonful of baking powder. This should be fried with butter and made into small cakes. Soy Bean Cheese.-In China and Japan the bean is used chiefly in the form of a cheese-like substance, the most common forms of this being natto, tofu, miso, yuba, and shoyu. These cheeses are eaten daily by almost all the inhabitants of the East, but they are said to have a lack of flavor that renders them more or less unsuited for European and American palates. In Seattle, Wash., and other places in the West we are informed that tofu is made by the Japanese and sold to the Oriental residents. We have not had any personal experience so far with the bean cheeses, although they are evidently very easy to manufacture. One may be made from the gruel which resembles somewhat curds and whey, but which in the only form we have tried is not sufficiently palatable for use, although very slight flavoring might make it a valu- able food for American use.

The methods of cutting sides of beef, veal, mutton, and pork into parts, and the terms used for the different " cuts," as these parts are commonly called, vary in Fig. 5.-Diagrams of cuts of beef: 1, Neck; 2, chuck; 3, ribs; 4, shoulder-clod; 5, fore-shank; 6, brisket; 7, cross-ribs; 8, plate; 9, navel; 10, loin; n, flank; 12, rump; 13, round; 14, second-cut round; 15, hind-shank.-(Atwater and Bryant, Bulletin No. 28, Office of Experiment Stations, United States Department of Agri, culture.) different localities. The analyses here reported apply to cuts as indicated by the following diagrams. These show the positions of the different cuts, both in the live animal 1This section is quoted from Atwater and Bryant, Bulletin No. 28, Office of Experiment Stations, United States Department of Agriculture. 433 434 DIETETICS FOR NURSES. and in the dressed carcass as found in the markets. The lines of division between the different cuts will vary slightly, according to the usage of the local market, even where the general method of cutting is as here indicated. The names of the same cuts likewise vary in different parts of the country. Cuts of Beef.-The gen- eral method of cutting up a side of beef is illustrated in Fig- 5, which shows the rela- tive position of the cuts in the animal and in a dressed side. The neck piece is frequently cut so as to include more of the chuck than is represented by the diagrams. The shoul- der-clod is usually cut without bone, while the shoulder (not included in diagram) would include more or less of the shoulder blade and of the up- per end of the fore-shank. Shoulder steak is cut from the chuck. In many locali- ties the plate is made to in- clude all the parts of the fore- quarter designated on the diagrams as brisket, cross- ribs, plate, and navel, and different portions of the plate, as thus cut, are spoken of as the " brisket end of plate " and " navel end of plate." This part of the animal is largely used for corning. The ribs are fre- quently divided into first, second, and third cuts, the CUTS OF MEAT. 435 latter lying nearest the chuck and being slightly less desirable than the former. The chuck is sometimes sub- divided in a similar manner, the third cut of the chuck being nearest the neck. The names applied to different portions of the loin vary considerably in different locali- ties. The part nearest the ribs is frequently called " small end of loin " or " short steak." The other end of the loin is called " hip sirloin " or " sirloin." Between the short steak and the sirloin is a portion quite generally called the " tenderloin," for the reason that the real ten- derloin, the very tender strip of meat lying inside the loin, is found most fully developed in this cut. Porter- house steak is a term most frequently applied either to the short steak or the tenderloin. It is not uncommon to find the flank cut so as to include more of the loin than is indicated in the figures, in which case the upper portion is called " flank steak." The larger part of the flank is, however, very frequently corned, as is also the case with the rump. In some markets the rump is cut so as to include a portion of the loin, which is then sold as " rump steak." The portion of the round on the inside of the leg is regarded as more tender than that on the outside, and is frequently preferred to the latter. As the leg lies upon the butcher's table, this inside of the round is usually on the upper or top side, and is therefore called " top round." Occasionally the plate is called the " rattle." Cuts of Veal.-The method of cutting up a side of veal differs considerably from that employed with beef. This is illustrated by Fig. 6, which shows the relative position of the cuts in the animal and a dressed side. The chuck is much smaller in proportion, and frequently no distinction is made between the chuck and the neck. 436 DIETETICS FOR NURSES. Ihe chuck is often cut so as to include considerable of the portion here designated as shoulder, following more nearly the method adopted for subdividing beef. The shoulder of veal as here indicated includes, besides the portion corresponding to the shoulder in beef, the larger part of what is here classed as chuck in the adult animal. The under part of the fore-quarter, corresponding to the plate in the beef, is often desig- nated as breast in the veal. The part Fig. 6.-Diagrams of cuts of veal: i. Neck; 2, chuck; 3, shoulder; 4, fore-shank; 5, breast; 6, ribs; 7, loin; 8, flank; 9, leg; 10, hind-shank.-(Atwater and Bryant, Bulletin No. IS, Office of Experiment Stations, United States Department of Agri- culture.) of the veal corresponding to the rump of beef is here included with the loin, but is often cut to form part of the leg. In many localities the fore- and hind-shanks of veal are called the " knuckles." Cuts of I/amb and Mutton.-Fig. 7 shows the relative position of the cuts in a dressed side of mutton or lamb and in a live animal. The cuts in a side of lamb and mutton number but six, three in each quarter. The CUTS OF MEAT. 437 chuck includes the ribs as far as the end of the shoulder blades, beyond which comes the loin. The flank is made to include all the under side of the animal. Some butchers, however, make a large num- ber of cuts in the fore-quarter, including a portion of the cuts marked " loin " and " chuck " in Fig. 7, to make a cut designated as " rib," and a portion of the " flank " and " shoulder " to make a cut designated as " brisket." The term " chops " is ordinarily used to designate portions of either the loin, Fig. 7.-Diagrams of cuts of lamb and mutton: 1, Neck; 2, chuck; 3, shoulder; 4, flank; 5, loin; 6, leg.-(Atwater and Bryant, Bulletin No. 28, Office of Experi- ment Stations, United States Department of Agriculture.) ribs, chuck or shoulder, which are either cut or " chopped " by the butcher into pieces suitable for frying or boiling. The chuck and ribs are sometimes called the " rack." Cuts of Pork.-The method of cutting up a side of pork differs considerably from that employed with other meats. A large portion of the carcass of a dressed pig consists of almost clear fat. This furnishes 438 DIETETICS FOR NURSES. the cuts which are used for " salt pork " and bacon. Fig. 8 illustrates a common method of cutting up pork, show- Fig. 8.-Diagrams of cuts of pork: r, Head; 2, shoulder; 3, back; 4, middle cut; 5, belly; 6, ham; 7, ribs; 8, loin.-(Atwater and Bryant, Bulletin No. 23, Office of Experiment Stations, United States Department of Agriculture.) mg the relative position of the cuts in the animal and in the dressed side. The cut designated as " back cut " is almost clear fat, and is used for salting and pickling. The " mid- dle cut " is the portion quite gen- erally used for bacon and for " lean ends " of salt pork. The belly is salted or pickled or may be made into sausages. Beneath the "back cut" are the ribs and loin, from which are ob- tained " spare ribs," " chops," and roasting-pieces, here designated by dotted lines. The hams and shoul- ders are more frequently cured, but are also sold as fresh pork " steak." The tenderloin proper is a com- paratively lean and very small strip of meat lying under the bones of the loin and usually weighing a fraction of a pound. Some fat is CUTS OF MEAT. 439 usually trimmed off from the hams and shoulders, which is called " ham and shoulder fat," and is often used for sausages, etc. What is called " leaf lard," at least in some localities, comes from the inside of the back. It is the kidney fat. As stated above, cuts as shown in the diagrams here- with correspond to those of which analyses are reported in the tables beyond, but do not attempt to show the different methods of cutting followed in markets in differ- ent parts of the United States.
