Barley, being an excellent source of fiber, keeps your body toxin-free. Its grass, which is rich in dietary fiber, acts as a fuel source to the friendly bacteria in our large intestine. These bacteria help in fermenting the fiber content of barley, thereby forming butyric acid, which is the primary fuel for intestinal cells. It is greatly effective in maintaining a healthy colon. By keeping the intestine in proper health, it helps you decrease the movement time of feces and also keeps your stomach clean. It greatly reduces the chances of colon cancer and hemorrhoids as well.
