Of what use, then, are starch, sugar, and the fats? Their use is chiefly, if not wholly, to keep up the heat of the body. They are a part of the fuel, which is burning up every where with the oxygen that is in the blood, as you learned in the chapter on Animal Heat. The power of an article of food to nourish the body or promote its growth is supposed to depend on the amount of nitrogen there is in it. Rice is not very nutritious, because it contains a great deal of starch and very little gluten. The common grains, as wheat, rye, etc., are among the most nutritious vegetable articles, for there is much gluten in them. There is a great deal in the coverings of the grains, which, broken up, make the bran. Therefore bread made from bolted flour is not as nutritious as that which is made from the unbolted flour. Peas and beans are very nutritious, because they contain so much of that nitrogenous substance, casein, or vegetable cheese. Cabbage is one of the most nutritious of vegetables, for it has even more gluten in it than the grains; and cauliflower has a still greater supply of it than the cabbage. There is some gluten in leaves and grass, but not so much as in the grains. The horse, therefore, though he may do pretty well upon hay alone when idle, must have some kind of grain when he is worked. The wear and tear of the muscles in working makes a good supply of nitrogenous food necessary for repair. The camelopard, with his long neck, lives by browsing upon the leaves of trees. But if he worked, like the horse, he would require some food richer in gluten. Food of the laboring man. How bread is "the staff of life. For the same reason, the food of...
