As the contents of the colon move at a better rate, there is thought to be less toxic exposure to the interior of the colon thereby reducing risk of developing colon cancer.
British and Dutch researchers analyzed 25 studies that included a total of nearly 2 million people. Compared with the lowest levels of fiber consumption, each 10 gram per day increase in intake of total dietary fiber and cereal fiber was associated with a 10 percent reduced risk of colorectal cancer.
Consuming 90 grams more a day (three servings, or three and one-quarter ounces) of whole grains was associated with about a 20 percent lower risk.
