Soy is one of the oldest and more nutritious foods in the world. In the 11th
century BC, it was used mainly in North China, extending to the west and the
United States in the mid 18th century and more recently in Europe. Soya has
many nutritional values, because it contains protein, fiber and isoflavones,
which have positive effects on cholesterol, bone density, menstrual and
menopausal symptoms and prevention of certain forms of cancer.
