In chronic cases it is also well to follow a milk diet for a number of weeks. The quantity of milk for an exclusive milk diet must depend on the age and size of the patient as well as on his ability to exercise. If he is confined to his room, from ten to sixteen glasses of milk a day are sufficient. If he is taking a great deal of exercise, he may take from eighteen to twenty glasses of milk a day. If he loses weight on the milk diet, bread and rice may be added, or potato soup, cereals, tapioca, and various gruels. If the milk is not well borne, malted milk or predigested milk with butter and cream may be substituted. If the casein in the milk is not well digested, cheese must not be used. An egg once or twice a week and fruit and fresh vegetables may be given, but meat should be omitted. A. F. Pattee gives the following diet in Bright’s disease. _DIET_ _Soup._—Vegetable or fish soup, broths with rice or barley. _Fish._—Raw oysters or clams, fresh fish broiled or boiled. _Meats._—Eat sparingly, chicken, game, fat bacon, fat ham. _Farinaceous._—Stale bread, whole wheat bread, toast, milk toast, biscuits, macaroni, rice, cereals of all kinds. _Vegetables._—Onion, cauliflower, mashed potatoes, mushrooms, lettuce, watercress, spinach, celery, cabbage. _Desserts._—Ripe raw fruits, stewed fruits, rice, tapioca, bread and milk puddings, junkets, cocoa. _Liquids._—Toast water, weak tea, pure water, peptonized milk, malted milk, fresh buttermilk, milk and hot water in equal parts, whey, unfermented grape juice. AVOID.—Fried fish, corned beef, hashes, stews, pork, veal, heavy bread, batter cakes, lamb, mutton, beef, gravies, beans, peas, malt or spirituous liquors, tobacco, coffee, ice cream, cake, pastry. This diet is tentative only and may be modified to suit the individual. If improvement is manifest after a month or two of the restricted diet, steak, roast beef, and eggs may be gradually added. If, when the urine is examined, the use of meat causes a return of albumin, it must be dropped. In these cases, active outdoor exercise, full, deep breathing systematically practiced at intervals, a calm quiet attitude of mind and care not to overeat and to keep the bowels active will materially aid recovery. * * * * * [Sidenote: Uremia or Uremic Poisoning] Interference with the action of the kidneys is apt to result in a retention within the system of the elements which they, in normal condition, eliminate from the system—such as urea, uric acid, urates, sulphates, phosphates, etc. They are the result of the oxidation and the breaking down of the proteins of the body. If the kidneys do not eliminate these the result is a systemic poisoning, and the dietetic treatment must be such as will aid them to act freely. Fruits should be used freely. The citrus fruits (lemons, oranges, limes, etc.) are the best; they neutralize acids and promote the alkalinity of the blood.
