Diverticulosis is the presence of weak areas or tiny pouches in the wall of the body’s intestine. Pouches generally appear in the lower part of the intestine known as the colon. The pouches, called diverticula, look like small protrusions or tiny balloons poking out of the side of the colon.
A diet high in fiber is known to be very beneficial in the prevention and treatment of diverticulosis. Dietary fiber increases the movement of food through the digestive track, promoting regular bowel function and the reduction of abdominal pain and gas. Fiber is most prevalent in raw, fresh fruits and vegetables, whole grain products, high fiber cereals and bran. The daily recommended intake of dietary fiber is 20-35 grams for adults. Introduce additional fiber into your diet slowly in order to avoid bloating, abdominal gas and diarrhea.
