Soy Proteins work to lower cholesterol?
Various bioactive components in soy protein have been suggested to explain the cholesterol-lowering effects of soy protein. Studies have shown that soy protein enhances bile acid secretion, which has the effect of removing cholesterol from the blood. Other studies have shown that soy protein stimulates the liver to remove LDL-cholesterol from the blood. Several studies have also suggested that the amino acid profile of soy protein as well as bioactive components such as isoflavones are crucial cholesterol-lowering components. There is ongoing research examining the mechanisms by which soy protein lowers blood cholesterol. In response to a petition submitted by Protein Technologies International (PTI), the FDA has authorized a health claim on the relationship between consuming soy protein and the reduced risk of heart disease. Authorization for use of the health claim allows food manufacturers that meet certain criteria to label their foods with the health claim.
