=Potatoes= consist principally of starch and water, with a certain amount of potash. Their dietetic value is not high. =Wholewheat Bread= contains, in addition to its starch, much vegetable albumen, and a large supply of mineral salts, such as phosphates, etc. It is, therefore, when light and well cooked, of high dietetic value both for flesh-forming and nerve feeding. Physical workers should use it as a staple article of food, and mental workers will also find it most helpful. The coarser the brown flour, the more laxative is the influence of the bread. This is point worth noting. =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. =HYGIENIC INFORMATION.= [Sidenote: =How to Keep Young.=] Old age is accompanied by the accumulation in the body of certain earthy salts which tend to produce ossification. The deposit of these in the walls of the arteries impedes the circulation, and produces senility and decrepitude. Flesh-food accelerates this process, but the juices of fruits, and distilled or soft water, dissolve out these deposits. The older one becomes the more freely should one partake of fruit and soft water. The more juicy fruit we consume, the less drink of any kind we require, and the water contained in fruit is of Nature's purest and best production.
