The substitution of ingredients is prompted wholly by a desire for gain, and consists in the substitution of a cheaper for a more expensive article. It is, therefore, a question of ethics rather than of health. If the horse-radish is largely turnip, and the apple-butter chiefly pumpkin, if the currant or raspberry jelly is made of the rich juices of the parings and cores of apples, strained, colored and delicately flavored, who will say that the cheaper fraud is not as wholesome as the more expensive genuine article? In some instances there is an actual advantage to health in the substitution, but this does not justify the deception. Pure, fresh oleomargarine, however wholesome, should not be sold for butter, any more than shoddy cloth should be sold for pure wool. =Dangers to Health.=--The contents of tin cans are sometimes affected by the action of the acids upon the tin or the solder. Food should not be allowed to stand in a tin can after being opened. Milk, cream, and butter are quick to take up germs of disease. Scarlet fever and typhoid fever have, in many instances, been traced to this source. The utmost cleanliness and care should be exercised in their handling. =The Diet Cure.=--Over-indulgence in eating is the source of many disorders of the system. It is well, at all times, to keep within the limit of the powers of digestion. The way to give the stomach rest is to eat less food and at longer intervals. Obesity is the result of the accumulation of the fatty properties of the blood in excess of what is needed to repair the waste of the system. The fattening process will be stopped by cutting off the supplies. A restricted diet, the avoidance of fat-producing foods, vigorous perspiration as the result of exercise, and frequent bathing, followed by friction, will be attended by a decided reduction of the superfluous fat. A merchant in England who had reached the enormous weight of four hundred and fifty-seven pounds put himself upon a diet of four ounces of animal food, six ounces of bread, and two pounds of liquid in twenty-four hours. In one week he had reduced his weight thirty pounds, and in six months he had lost one hundred and thirty-four pounds. In France, there is a method of treatment known as “The Grape Cure.” Persons in Paris, broken down by the excitements and dissipations of the city, go off among the vineyards, breathe the pure country air, and live on grapes. From eight to twelve ounces of bread, with grapes at discretion, constitute their daily allowance of food and drink. By this treatment the impurities of the system soon pass off through the kidneys, the bowels, the lungs, and the pores of the skin, and pure, wholesome blood takes the place of that which was diseased.
