The soybean (or soya bean) is a plant with fruit called beans, from Eastern Asia. The height of a grown soybean is between less than 20 cm and up to 2 m. One soybean lives for only one year. Probably, it was originally a vine.
In 1997, 81% of all soybeans were of genetically modified stock. This means that genes were changed directly.
In China, going back the ancient Chou dynasty soy beans were considered to be one of the five sacred foods.
