What is one effect of dietary fiber on cholesterol levels?

Dietary fiber is known to have a beneficial effect on cholesterol levels, primarily through its ability to bind to cholesterol in the digestive system. This binding action helps to prevent the absorption of cholesterol into the bloodstream, effectively reducing total cholesterol levels in the body. When soluble fiber is consumed, it forms a gel-like substance in the gut, which can trap cholesterol and bile acids. As a result, the liver must draw upon its cholesterol stores to produce new bile acids, ultimately leading to a decrease in blood cholesterol.

The body benefits from this mechanism, as lower cholesterol levels can contribute to reduced risk of heart disease and improved overall cardiovascular health. Therefore, dietary fiber plays an important role in managing cholesterol levels and promoting heart health.
