What are soy beans?
The soy bean comes from a leguminous plant (Glycine max) that grows pods with clusters of two to three beans. The color of the bean varies from shades of brown to green and the shape can be oval or round. People began cultivating soy beans in Northern China three centuries ago. Today soy beans are used in many food products, including soy milk, soy cheese, soy yogurt and tofu.
