Abstract

The effect of soybean resistant protein (RP) on serum and hepatic cholesterol levels and fecal excretion of steroids was examined. RP decreased cholesterol in the liver, probably due to the stimulated excretion of cholesterol and its metabolites, bile acids. The serum cholesterol level was not different as between RP and other soy-derived proteins.
