Dietary fiber, lipids and atherosclerosis

Abstract

Dietary fiber has important hypocholesterolemic effects and may reduce risk for coronary artery disease. Careful clinical studies indicate that foods such as oat bran or beans, rich in water-soluble fiber, can decrease serum total cholesterol by 19% while decreasing serum low density lipoprotein cholesterol by 22%. Food supplements rich in soluble fiber such as psyllium mucilloid are well tolerated and may lower serum cholesterol by 15%. Thus, high fiber foods or soluble fiber food supplements may decrease serum cholesterol by 15% to 19% and decrease estimated risk for coronary heart disease by greater than 30%.
