Fiber and bowel disorders
High fiber diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis.
In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome (IBS) (also called spastic colitis, mucus colitis, and nervous colon syndrome.) It is generally accepted that a diet high in fiber is protective, or at least reduces the incidence, of colon polyps and colon cancer.
