Many studies show that eating a fiber-rich diet can help control diverticular symptoms. Fiber helps prevent constipation; it softens and adds bulk to stools, helping them pass more easily through the colon. It can also help decrease pressure in the colon and prevent flare-ups of diverticulitis. However, foods high in fiber should be avoided during a flare-up for people who have diverticulitis, as this can provoke the symptoms. If you have diverticulitis, firstly, we would highly recommend consulting with your doctor before taking ColonBroom.
