To prevent diverticular disease or reduce the complications from it, maintain good bowel habits. Have regular bowel movements and avoid constipation and straining. Eating appropriate amounts of the right types of fiber and drinking plenty of water and exercising regularly will help keep bowels regulated.
Experts recommend 20 to 35 grams of fiber a day. Every person, regardless of the presence of diverticula, should try to consume this much fiber every day. Fiber is the indigestible part of plant foods. High-fiber foods include whole grain breads, cereals, and crackers; berries; fruit; vegetables, such as broccoli, cabbage, spinach, carrots, asparagus, squash, and beans; brown rice; bran products; and cooked dried peas and beans, among other foods. Drinking eight 8-ounce glasses of water a day, monitoring changes in bowel movements (from constipation to diarrhea) and getting enough rest and sleep, are other ways to prevent diverticular disease.
