How does soluble fiber in kidney beans contribute to reducing LDL cholesterol levels?
It binds to cholesterol particles and bile acids, preventing reabsorption.
The soluble fiber present in kidney beans provides a dual benefit to the digestive and cardiovascular systems, particularly concerning lipid profiles. When this type of fiber dissolves in water within the digestive tract, it forms a viscous, gel-like substance. This gel matrix physically traps dietary cholesterol particles and bile acids that the body attempts to reabsorb into the bloodstream after digestion. By binding these compounds and escorting them out of the body via feces, the absorption of LDL, commonly known as "bad" cholesterol, is significantly interrupted. This reduction in circulating LDL levels is a fundamental mechanism by which a diet incorporating legumes supports long-term arterial health and a favorable lipid panel.
