UCSF Medical Center recommends a high-fiber diet for those with diverticulosis. Beans and legumes, whole-grain products, brown and wild rice, and fruits and vegetables are some foods to include in a high-fiber diet, and people should strive to consume 25 to 30 grams of fiber each day. Fiber prevents constipation by softening and adding bulk the stool and easing pressure in the colon so that the stool passes quickly and easily from the body and making it less likely that diverticular pockets become inflamed and infected. Drinking plenty of fluids also helps soften the stool.
If the diverticuli become inflamed and/or infected, diverticulitis is present, explains UCSF Medical Center. Patients must consume a liquid diet consisting of broth, clear juices, gelatin and ice pops during these flare-ups. Once symptoms subside, the patient is permitted to eat low-fiber foods, gradually adding small amounts of fiber back into the diet. Patients can resume their high-fiber diets once diverticulitis symptoms fade.Learn more about Gastrointestinal Issues
