Viscous fiber, which is a type of soluble fiber, binds with bile in the intestine and is excreted in feces. Bile is made from cholesterol in the liver, so when the viscous fiber binds with bile, it reduces the amount of cholesterol in the body. This, in turn, can help to lower blood cholesterol levels, reducing the risk of heart disease. Insoluble fiber, on the other hand, does not bind with cholesterol in the blood. Instead, it adds bulk to the stool and helps to regulate bowel movements.
