Soybeans contain almost 40 percent protein and 20 percent oil, giving them multiple uses. They may be used as food, in supplements, or for industrial purposes.
Soybeans are a high-protein food that can be cooked and eaten in a variety of ways. The beans can be green, black, yellow, or white.
Young, green soybeans are also called edamame. They can be steamed and eaten out of the pod as an appetizer. Shelled edamame can also be used in salads, stir-fries, and soups.
Yellow soybeans are typically used to make soymilk, tofu, tempeh, and tamari. They can also be used to make soy flour for baking.
Soybeans also provide soy oil, which can be used for cooking, or as an ingredient in many foods. After the oil has been removed from soybeans, the remaining material can be used to make food for farm animals and pets.
Soy is used to make soy protein powder, as well as soy isoflavone supplements.
Soy has many industrial uses. It can be used to make products including biodiesel, building supplies, carpeting, candles, ink, and paint.
Soy is a complete protein, which means that it contains all nine essential amino acids. It is an important protein source for many people, especially vegans and vegetarians.
