In all vegetarian diets, under normal conditions, the legumes should be used freely to replace meats. All legumes must be thoroughly cooked and thoroughly masticated. Because the protein in these foods is less digestible than that in meat or eggs, particularly if they are not thoroughly masticated, they are better adapted for the use of those who do manual labor. Soldiers in battle, day laborers, and others whose work calls for hard physical exercise, can digest legumes more easily than can those whose occupation is more sedentary. If not thoroughly masticated legumes usually produce intestinal fermentation with consequent production of gas. For this reason they occasion distress in those who partake of them too freely and with insufficient preparation by cooking. The protein of the legumes is of the same nature as the casein of milk. It has been called vegetable casein. _Peanuts._ While an underground vegetable, grown like potatoes, peanuts resemble nuts, inasmuch as they contain so much fat. The extracted oil is used in several commercial products. Like other legumes, they require cooking. They are roasted because this develops the flavor.
