Soy is a legume of the Papilionaceae family, to which plants such as beans and peas belong. It is an annual plant up to 1.5m high with white or purple flowers. The fruits are legumes up to 7cm long with one or four seeds inside. These have different colors, depending on the variety in question (mainly yellow, black or green).
Soybeans originate from Southeast Asia. Since Eastern religions prohibited the consumption of animal meat, soy was imposed from the beginning as an essential crop to supply the protein that they could not acquire from meat. In fact, in these regions it is known as “field meat”, since it is often used as a meat substitute.
