What are the benefits of insoluble and soluble fibers to the body? What functions do insoluble and soluble fibers perform, respectively?
Humans lack the enzymes needed to break the chemical bonds of the cellulose (fiber) chain. However, fiber remains an extremely important part of a well-balanced diet for good health. Insoluble Fiber: Its major functions are to promote satiety (makes you feel full faster), to expand the fiber in the stomach, to promote regular bowel movements, and to make your stool softer. Soluble Fiber: The FDA has recognized that certain soluble fiber (like that found in oats & barley), help lower the Cholesterol levels: Lowering the Cholesterol levels: Dietary fiber can merge with bile acid to reduce the rate of fat absorption. In humans, bile acids are derivatives of cholesterol synthesized in the liver cells, and cholesterol can be eliminated in bile to reduce cholesterol levels. Maintaining the normal functions of the mucosal barrier: Soluble fiber can be dissolved in the intestines by intestinal bacteria to help maintain the normal defensive functions of the intestinal mucous membrane.
