|What is soy, and what is it used for?|
Soy is a highly popular annual crop that produces edible beans. The plant has many varieties, some of which can grow up to 2 meters high. Soybeans are rich in proteins (40%-50%) and oil (20%). Soy yields lots of protein per hectare and its price-quality ratio compares favorably with other protein sources. Soy oil has a favorable fatty acid composition. Worldwide, soy has therefore become a major source of vegetable protein and oil for both humans and farm animals.
