Direct Quote: "The purpose of this study was to evaluate the effect on serum lipids of a yeast-derived ß-glucan fiber in 15 free-living, obese, hypercholesterolemic men. ... The yeast-derived ß-glucan fiber significantly lowered total cholesterol concentrations and was well tolerated…The link between elevated plasma LDL-cholesterol concentrations and the risk of developing coronary artery disease has been clearly established…Elevated plasma cholesterol and, in particular, LDL-cholesterol concentrations are associated with increased risk of coronary artery disease, whereas an elevated of HDL-cholesterol concentration is inversely correlated with the incidence of cardiovascular…The yeast-derived ß-glucan fiber lowered total cholesterol and raised HDL-cholesterol concentrations significantly. Unlike the significant increases in HDL-cholesterol concentrations observed 4 wk after the end of the study for subjects receiving the yeast-derived ß-glucan, none of the 24 studies of oat products reported significant changes in HDL concentration. …Because higher HDL-cholesterol concentrations are associated with a reduced risk of developing coronary artery disease, there may be unique benefits of using the yeast-derived ß-glucan, and perhaps psyllium, rather than the oat products."
