A liquid diet of broth, gelatin and fruit juices calms diverticulitis, states WebMD. Switching to a high-fiber diet and consuming foods like brown rice, whole grains and vegetables prevents recurrences. Eating foods with low fiber may bring on diverticulitis, so adding fiber to the diet helps stave it off.
Fiber contributes to the quick passage of materials through the colon. Without fiber to facilitate the movement of the substances, the colon has to work harder to push stool through the intestine, says WebMD. This stress can cause pouches to develop in the colon. When the pouches become infected, the result is diverticulitis, which causes bloating, nausea and lack of appetite.
People suffering from diverticulitis should switch to a liquid diet for a few days in order to rest the digestive system. After the digestive system recovers, WebMD recommends eating high-fiber foods like fruits and vegetables. Individuals can drink liquids during the day to complement a high-fiber diet, suggests Mayo Clinic.
Eating at regular times intervals the colon as well, claims WebMD. Diverticulitis sufferers should also not strain when passing a bowel movement in order to avoid stress to the colon. They should also avoid using laxatives too often, as the body can begin to depend on them.
