Soybeans or soya beans (Glycine max) are a type of legume, native to eastern Asia.

They are an important component of Asian diets and have been consumed for thousands of years. Today, they are mainly grown in Asia, and South and North America.

In Asia, soybeans are often eaten whole, but in Western countries heavily processed soy products are much more common.

Various soy products are available, including soy flour, soy protein, tofu, soy milk, soy sauce, and soybean oil.

Soybeans contain antioxidants and phytonutrients that have been linked with various health benefits, while concerns have also been raised about adverse effects.
