Which type of fiber can help lower cholesterol levels?

Soluble fiber is known for its ability to help lower cholesterol levels in the body. When soluble fiber is consumed, it binds to cholesterol in the digestive system, which can lead to a reduction in the absorption of cholesterol into the bloodstream. This process can effectively lower levels of low-density lipoprotein (LDL), often referred to as "bad" cholesterol. Foods that are high in soluble fiber include oats, legumes, fruits, and certain vegetables.

In contrast, insoluble fiber plays a different role in digestion; it adds bulk to the stool and helps with regularity, but it does not have a significant effect on cholesterol levels. Resistant starch and animal fiber do not demonstrate the same benefits related to cholesterol reduction as soluble fiber does. This makes soluble fiber a valuable component of a heart-healthy diet.
