Eggs are nutritive chiefly on account of the albumen which they contain in the white portion, but they are liable to cause digestive trouble, and they must not be taken too freely by those who are subject to biliousness and constipation. Such persons often find it advantageous to have them boiled quite hard.
Emprote (Eustace Miles proteid Food) contains the proteids of wheat and milk (35%), with digestible Carbohydrates (45.2%), fat (6.6%), and assimilable salts (7.9%). It makes a good addition to soups, beverages, and dishes lacking in protein.
Nuto-Cream Meat is a modern substitute for white meat and poultry, containing 19.7% protein, 48% fat, and 23% Carbohydrates. It is made from nuts and corn, and is useful for invalids and young children.
Milk contains nearly all the elements necessary for repairing bodily waste. It should be scalded for half-an-hour in a double saucepan—to destroy tubercular and other germs. If then allowed to stand for 12 hours, clotted cream can be skimmed off (as in Devonshire) and the milk can be used next day. It keeps much longer after being thus scalded. Dried milk is now procurable in such forms as 'Lacvitum' and 'Plasmon.'
Celery is a useful blood purifier, and is valuable in all cases of rheumatism, gout, &c. Celery salt is a valuable addition to soups and savoury dishes, and is preferable to common salt.
Spinach contains a considerable quantity of iron in a readily assimilable form, and is, therefore, good for anæmic persons.
Onions have a wonderfully improving effect upon the skin and complexion if eaten raw, and they act powerfully as diuretics.
