        stimulates peristalsis in the intestine. It is found
        especially in grains, fruits, and vegetables. There is
        some medical evidence which indicates that diets high in
        fiber reduce the risk of colon cancer and reduce

        afterward relieved suddenly by letting a lid at the muzzle
        fly open, when the rapid expansion separates the fibers.
