There are over 2,500 varieties in cultivation, producing beans of many sizes, shapes, and colors. As a crop, soybeans are high in yield and easy to harvest; they grow well wherever corn is cultivated.
In East Asia, soybeans are used in a multitude of forms, e.g., as soy sauce, soybean meal, vegetable oil, tofu (bean curd), miso (fermented soybean paste), and soy milk, and as a coffee substitute.
