The dos and don’ts of managing diverticular disease

People who have diverticular disease have tiny pouches (diverticula) in the lining of the colon that can bleed or perforate and develop infection (called diverticulitis). People with diverticular disease should eat a healthy diet rich in fiber, drink lots of water, exercise regularly, maintain a healthy weight, not smoke, avoid straining in the bathroom, and report bleeding or pain to a doctor. However, it’s not necessary to avoid eating nuts, seeds, or popcorn, which were once believed to lodge in diverticula and cause problems. That old advice turned out to be wrong.
