Cholesterol-lowering effects of soluble-fiber cereals as part of a prudent diet for patients with mild to moderate hypercholesterolemia

Abstract

Soluble-fiber breakfast cereals were examined for their cholesterol-lowering ability in 58 male patients with mild to moderate hypercholesterolemia in a randomized, double-blind, placebo-controlled study. Patients followed a step 1 diet for a minimum of 6 wk, then were randomly assigned to groups incorporating either corn flakes or one of two soluble-fiber cereals (pectin enriched or psyllium enriched) in the diet for an additional 6 wk. During the diet-only phase, total cholesterol dropped 3.8%. During the cereal-plus-diet phase, total and LDL cholesterol values of the pectin-enriched cereal group dropped an additional 2.1% (P = 0.243) and 3.9% (P = 0.16), respectively, and they dropped 5.9% (P = 0.005) and 5.7% (P = 0.034), respectively, in the psyllium-enriched cereal group. During the cereal-plus-diet phase, no significant effects on HDL cholesterol, triglyceride, or body weight were found within or between any cereal groups. These results support use of soluble-fiber cereals as an effective and well-tolerated part of a prudent diet in the treatment of mild to moderate hypercholesterolemia.
