Fiber
Fiber-rich foods slow the entry of food into the bloodstream and increase the rate at which it leaves the digestive system. They also balance blood sugar and cholesterol levels, quickly remove toxins from your intestines, and reduce appetite. Fiber is also vital for feeding friendly gut bacteria. Most people think that bran is the best type of fiber to eat. However, bran, or wheat fiber, is mostly insoluble and indigestible. This keeps your bowels regular, but it cannot help your health in the way that soluble fiber can. You can find soluble fiber in fruits, vegetables, beans, nuts, seeds, and most whole grains.Medical Guide
