Health on the Farm: A Manual of Rural Sanitation and Hygiene

by H. F. Harris

First in the list of foods the writer would place those nitrogenous substances commonly eaten that belong to the class of albumins. That these substances are in reality the most important of all food-stuffs there can be no sort of question, since they, of all things eaten by the human being, are alone absolutely essential for his well being and even his existence. They are the substances that almost exclusively go to make up the muscle and tendons. Along with the lime-salts they enter largely into the composition of the bones and cartilages, brain, spinal cord and nerves. Other foods are incapable of taking the place of the albumins, so that they are absolutely essential for normal life in the human being.

The amount of albumin necessary for the normal adult has been variously estimated, the tendency at the present time being to place the quantity needed somewhat lower than was at one time done. It is probable that about two ounces of pure albumins is somewhere near the amount required in twenty-four hours by a normal adult.

It is well, since we are so dependent on foods of this class, that we have two quite distinct sources from which they may be taken. The great bulk comes to us in the form of meats, including poultry, game, oysters and fish of various kinds, in addition to beef, mutton, and hog-meat in its several forms. Of animal origin also we have eggs, which are among the most valuable of all foods of this class on account of their high digestibility.

From the vegetable world we get albumins known as legumins, which differ somewhat from those obtained from animal sources, though taking their place in the economy in all essential particulars. Unfortunately the legumins are usually so mixed with starches and other vegetable substances less digestible, that it is necessary to take a large bulk of foods of this latter class in order to secure anything like the requisite amount of the former.

Before taking up individually the various albuminous foods, the writer would again direct attention to the chapter on cooking, and would strongly urge upon the reader the proper methods of preparing nitrogenous foods therein stated. Where the albumins are in a nearly pure state, as in milk and eggs, they are slightly more digestible when raw, but all meats should be cooked until only the faintest tinge of red remains if we wish to have them prepared in the most wholesome way for those with delicate digestions. Meats are, as a rule, most wholesome when cooked “very done.”

It has long been the cry of sentimentalists that no living being should die in order that man might exist. Unfortunately for such theories, the stern and unbending edict of nature has negatived views of this kind ages before the altruistic philosopher came on the scene, and we are daily constrained to bow to this mandate of one of the primal laws of existence. However much we might desire it otherwise, it has been written that “only in death is there life;” nor may any animal being disobey and continue to exist. As has been already explained, the human being cannot thrive on vegetable substances alone; from them he may get a certain amount of nitrogen in the form of legumin, but there is not enough to make up for the waste of this substance that constantly goes on in the body.

Theoretically it is of very little importance which of the meats are selected to supply our nitrogenous food, but it is unfortunately true that such foods vary much in digestibility, and it will therefore be necessary to consider them separately.

Beef.—When tender and cooked to a proper degree, beef is considered one of our most wholesome of meats. Like other foods of this kind, it should not be fried, but should be broiled or roasted, and a certain amount of fat may be eaten along with the lean portions without injury, and in many persons unquestionably with benefit.

Mutton.—Of all the coarser meats, mutton is unquestionably the most digestible, and when cooked in the same way as directed for beef is eminently wholesome.

Hog-meats.—On account of the large portion of fat between the muscle-fibers, hog-meat, particularly when fresh, is not usually regarded as being digestible. Some persons eat it with impunity, but for the vast majority it should be taken only in small quantities. It should not be fried. In the form of ham, hog meat is more wholesome than when fresh, but even in this condition many dyspeptics find much difficulty in digesting it. The best method of cooking it is to boil thoroughly. After being cooked in this way and then broiled, it is most appetizing, and is much more wholesome than when broiled without being previously cooked. As bacon, hog-meat enters largely into the dietary of a great portion of the laborers of this country, and there can be no doubt that on the whole it answers the purpose of a staple food admirably. It contains even more fat than nitrogenous substances, and may therefore be looked upon as a mixture of butter and meat. Dyspeptics cannot eat it with impunity in many instances, though it agrees far better with them than does ham or the fresh meat. If it were generally eaten boiled it would provoke less trouble than when fried. At this point the writer would repeat his warning concerning the indigestible character of melted grease, of which the gravy from bacon is a striking example.
