Fiber, Bulk and Colonic Activity
There is only one point definitely known about fiber and colonic activity, namely that fiber produces a rather larger stool. The rest of the information is speculative. Fantus and his colleagues studied various types of bran and noted an increase in stool weight which varied from 50% to nearly 100%. They also showed that some individuals have a decrease in stool weight of between 16 and 40% when they take additional fiber.
