They contain the highest amount of protein of any grain or legume, and substantial amounts of fat, carbohydrates, dietary fiber, vitamins, minerals and a virtual drugstore of phytochemicals useful for the prevention and treatment of many chronic diseases.
Soybeans vary widely in nutrient content based on the specific variety and growing conditions, but typically they contain 35-40 percent protein, 15-20 percent fat, 30 percent carbohydrates, 10 to 13 percent moisture, and around 5 percent minerals and ash.
