|The Facts About Dietary Fiber and Weight Loss
Fiber is an essential carbohydrate food component that is necessary for maintaining good health. The addition of dietary fiber to one's diet has been shown to lower cholesterol and high blood pressure, reduce the risk of cardiovascular disease and improve blood insulin levels. In addition, it aids digestion by promoting the growth of "good" intestinal flora.
As an aid in losing weight, fiber acts as a bulking agent in the stomach which means you feel fuller faster and eat less. Fiber aids in digestion by moving food more quickly through the digestive system helping to keep bowels regular, stools soft, and preventing the accumulation of metabolic waste and toxic by-products. Soluble fibers such as psyllium, guar, and the pectins help absorb dietary fat and prevent its assimilation into the bloodstream.
Carbohydrates, fruits, and vegetables are all high in fiber. Wheat bran, whole grain products, and beans are major sources of fiber that help to alleviate constipation and keep the colon clean and healthy. Mucilaginous fiber which is thick and sticky enables the digestive system to absorb more slowly. This prevents the problem of flatulence and bloating that often accompanies bran and other high-fiber consumption. Psyllium seeds found in Fiber Food are a good source of mucilaginous fiber.
