The cholesterol-lowering effect of barley and more specifically the contribution of barley fiber and barley oil to cholesterol-lowering was studied in hamsters. This was achieved by comparing a semi-purified diet containing cellulose and peanut oil (control) to a whole barley diet and barley diets from which barley fiber, barley oil, or barley oil and barley fiber were removed. The barley fiber was removed enzymatically and the oil was extracted with hexane. The cholesterol-lowering effect of the barley oil was also tested by adding it in place of peanut oil to the control semi-purified diet. Plasma triglycerides and HDL cholesterol levels were not influenced by dietary treatments. Total plasma cholesterol was lower (P < 0.05) in hamsters fed diets containing barley soluble dietary fiber compared to those fed barley diets with SDF removed or those fed insoluble dietary fiber. Barley oil had no statistically significant lowering effect on plasma cholesterol levels compared to those of the controls. The data presented in this study with the hamster model supports the cholesterol-lowering effect of soluble fiber previously reported in other species, but does not support all reports concerning oils and nonsaponifiable oil constituents in this respect. |
