Dietary fiber and diverticular disease.Hosp Pract. 1976 Mar; 11(3):119-24.HP
Can the regular consumption of bran and other fibrous foods help in preventing diseases of the colon? Indirect evidence supports the idea, although much remains to be learned. It seems probable that bulkier feces could increase the diameter of the colon and prevent sudden sharp rises in pressure that are believed to be responsible for the formation of diverticula. For most people, fiber is probably harmless and it may do some good.
