The protein in soybeans is almost comparable in quality to animal protein. To be a complete protein, it needs only to be combined with a small amount of meat, milk or a cereal grain such as rice.
Soybeans are also rich in calcium, iron, phosphorus and some of the B vitamins.
Before you cook dry soybeans, sort them and remove any beans that are discolored, cracked or shriveled. Wash the beans thoroughly and soak them at least four hours or overnight. To soak the dry soybeans Add four cups of warm water and two teaspoons of baking soda to each cup of dry beans. One cup of dry beans will yield about two and one-half cups of cooked beans. After the beans have soaked Bring them to a boil in the soaking water and simmer for 20 minutes.
