what is soluble fiber and how does it work?

Soluble fiber is a type of dietary fiber that dissolves in water to form a gel-like substance. It helps regulate digestion by slowing the absorption of sugars and improving cholesterol levels. When consumed, soluble fiber can help maintain stable blood sugar levels, promote a feeling of fullness, and support heart health by lowering LDL cholesterol. Common sources include oats, beans, lentils, fruits, and vegetables.
