Which type of fiber is known to help lower cholesterol levels?

Soluble fiber is known for its ability to help lower cholesterol levels. This type of fiber dissolves in water and forms a gel-like substance in the digestive tract. When soluble fiber is consumed, it binds with cholesterol molecules in the intestine and helps to remove them from the body. By doing so, it can effectively reduce the absorption of cholesterol into the bloodstream, which may lower overall cholesterol levels and improve heart health.

In terms of types of fiber, insoluble fiber primarily aids in digestive health by adding bulk to stool and facilitating regular bowel movements, but it does not have the same direct effect on cholesterol levels as soluble fiber. Resistant starch and functional fiber may offer various health benefits, yet they are also not specifically recognized for their cholesterol-lowering properties like soluble fiber. This makes soluble fiber the key player when it comes to managing cholesterol levels effectively.
