What is a common characteristic of soluble fibers?

Soluble fibers are recognized for their ability to help lower cholesterol levels in the body. This occurs because soluble fiber dissolves in water to form a gel-like substance in the digestive tract. When consumed, soluble fiber can bind to cholesterol in the intestine, which helps to facilitate its excretion from the body. As a result, this contributes to lower levels of LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol, and promotes overall heart health.

In addition, soluble fibers can influence various other health aspects, such as stabilizing blood sugar levels and prolonging feelings of fullness. However, their most notable characteristic is their beneficial impact on cholesterol levels.
