The soybean or soya bean (Glycine max) is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses.
Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many types of meat and dairy substitutes.
Soybeans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in the food and industrial applications, is another product of processing the soybean crop. wiki
