The preferable way to prepare dishes for patients suffering from kidney diseases, is to boil them; the next best way is to steam them, and the third and least desirable way is frying. Strongly recommended: calf's feet and pig's feet, calf's head, especially in the form of jellies and pickled, if so ordered by the physician. Occasionally raw beef may be given, but without sharp spices. Fish: Trout, pike, carp; Saltwater fish: haddock and cod-fish, boiled blue; also frogs' legs. Eggs are permitted, soft boiled, 2 to 3 per day. Vegetables: With the exception of those mentioned, vegetables are very commendable, especially potatoes, green peas, white and yellow turnips, red beets, cauliflower, lentils, beans, the last particularly, mashed; also salad with cream and a little mild vinegar or lemon juice. Fruit-acids must not be classified with vegetable or meat-acids, as several, so-called "Food-Specialists" try to impress on patients, for they do not know, what they talk about. Fats, such as cream, butter, rich cheese, olive oil, may be given if they agree with the patient; bacon is not so good. Bread, white as well as brown, and especially Graham bread, may be eaten without restrictions. As drinks: mineral water with lemon or orange juice added. Raspberry juice is permitted, but currant and gooseberry juice must be avoided on account of the substances contained in them irritating to the kidneys. Fruit juices free from alcohol (apple cider) may be given. Every _morning_ on rising, a glass of fruit juice or some fruit. These fruit-acids promote peristaltics of the bowels, and free circulation of the blood. At _supper_: Salad of cresses or celery, or a mixed salad, radishes, asparagus, squash and cucumbers. When the urinary flows is very scanty, supper may consist of a cup of celery soup, or asparagus broth; in winter, haw tea. A few suggestions for _dinner_, omitting meat entirely: Dumplings with cabbage salad, red cabbage or Bavarian cabbage; sliced oatmeal cake with fruit.--Cucumbers with eggs and potato bread, rolled griddle cakes and fruit.--Cabbage with rice and butter, griddle cakes with fresh greens. Squash with lemon, potatoes, baked beans, fruit.--Red cabbage with macaroni, potato fritters, with fruit.--Dumplings and pears, lettuce.--White turnips with cream and potatoes, buckwheat groats, fruit.--Pea soup with sweet corn, squash and rice with fruit.--Lentils and potatoes, salad of celery or beets, fruit.--Asparagus with drawn butter and parsley sauce and bread dumplings, oat groats with fruit.--Cauliflower with macaroni, buckwheat groats and milk.--Cabbage with browned potatoes, oatmeal cake with fruit. _For Irritable Kidneys (Inflammation, Supperation, Contraction, etc.), and Diseases of the Bladder._
