Diet high in soluble fiber may prevent weight gain
Published in the American Journal of Physiology-Gastrointestinal and Liver Physiology, the study found mice fed a diet lacking soluble fiber experienced poor gut heath and gained weight.
Soluble fiber absorbs water in the gut, forming a gel-like substance that can bind to cholesterol and bile acids, helping to eliminate them from the body. As such, soluble fiber helps to lower cholesterol. The gel-like substance it forms also helps to slow digestion and regulate blood sugar.
