Frequently Asked Questions
Q: How is soluble fiber in the diet thought to help lower blood cholesterol level?
Soluble fiber in the diet is believed to help lower blood cholesterol levels by binding to cholesterol in the digestive system. This prevents the cholesterol from being absorbed into the bloodstream, allowing it to be eliminated from the body. Additionally, soluble fiber can increase the production of bile acids, which are made from cholesterol, resulting in the body using up more cholesterol to produce new bile acids. Both of these mechanisms contribute to lowering blood cholesterol levels.
