Rice, although low in protein and fat, is one of the most easily digested of all cereals, and is especially suitable for brain workers and people of sedentary habits. This book contains a large number of different recipes for the preparation of rice. SAGO AND TAPIOCA. They are manufactured from certain palms and roots, and belong to the lighter forms of cereals. They are easily digested if soaked for several hours before cooking, and can be partially substituted for the heavier cereals. Cornstarch, arrowroot, potato-flour and agar agar belong to the same class. They are all valuable for the sick and for young children. BARLEY. Barley is also rich in lime; it should take a more prominent place among food substances than it does. Pearl barley should be soaked with soft water before cooking. If it is to be strained, mash it up thoroughly with a potato masher, and pour more boiling water over it after the first liquid is strained off. ANIMAL FOODS. EGGS. Eggs contain all the elements necessary for the building up of a young animal; they also contain all the elements which can be found in the human body. The eggs of hens are used most commonly. The chemical combination of the whole egg and that of the brain and nervous system have much in common. The white of the egg contains about eighty per cent water, twelve of albumen, a small amount of fat and some salts. For medicinal purposes, eggs should be fresh, directly from the nest. Eggs are deficient in minerals and should be combined with foods which are rich in minerals. CHEESE. Cheese is one of the most economical and nutritious of foods, and a true meat substitute. To serve cheese after a dinner is a wasteful extravagance, and dangerous to health. Cheese combines well with bread, macaroni, potato and other cereals; raw greens are also a good addition. Cooking or baking cheese makes it indigestible. Grated or sliced is the best way to serve it. People who have difficulty in digesting cheese should always combine it with raw apples, onions, or tomatoes and lettuce, in the form of a salad. If it still disagrees, leave out the cereals entirely at the meal, or use black bread with it. A combination of cheese, eggs and milk in the form of a Welsh rarebit makes a heavy and indigestible meal, and should only be indulged in by people who are very strong, and exercise a great deal out of doors.
