soy beans, a complete protein profile

According to the US Food and Drug Administration,Soy protein products can be good substitutes for animal products because, unlike some other beans, soy offers a 'complete' protein profile. ... Soy protein products can replace animal-based foods—which also have complete proteins but tend to contain more fat, especially saturated fat—without requiring major adjustments elsewhere in the diet.However, as with many dietary health claims, there are opposing viewpoints on the health benefits of soybeans. Consumption of soy may also reduce the risk of colon cancer, possibly due to the presence of sphingolipids.
