Soluble dietary fiber (SDF) from whole grains, specifically beta-glucan and arabinoxylan, lowers cardiovascular disease risk by forming viscous gels that reduce bile acid reabsorption and cholesterol synthesis.
Focus on whole grains known for high soluble fiber content, such as oats and barley, to help manage cholesterol levels. Beta-glucan in these grains forms a gel in the gut that helps lower cholesterol.
GoodSupportsHIGH confidence
The protective effect of dietary fibre on CVDs may be due to the ability of SDF to form viscous gels. Increasing the viscosity of the gut content reduces the reabsorption of bile acids which, on its turn, reduces the circulation of cholesterol in blood.
Why this rating
Supported by multiple animal studies and FDA health claims, but the paper is a review.
