Abstract
The cholesterol-lowering effects of a fiber supplement were evaluated in patients with mild to moderate hypercholesterolemia. After a 9-wk diet stabilization period, patients were randomly assigned to treatment with 10 or 20 g/d of the fiber supplement or with a matching placebo. Among patients who completed the 15-wk treatment period, total cholesterol, LDL cholesterol, and the ratio of LDL to HDL (LDL/HDL) were significantly reduced (P < 0.05) for the 10- (n = 40) and 20-g/ d (n = 39) groups compared with the placebo group (n = 48). In the placebo group and 10- and 20-g/d groups, the percent changes in total cholesterol were 0.4%, −5.8%, and −4.9%, in LDL cholesterol were −0.4%, −8.1%, and −7.3%, and in LDL/ HDL were 1.0%, −5.6%, and −8.7%, respectively. The fiber supplement had no significant effects (P > 0.05) on HDL cholesterol or triglycerides. The changes in lipoprotein concentrations could not be attributed to changes in diet or body weight because there were no significant changes in these variables during the 15-wk treatment period.
