The results of past experiments are very reliable because these are the results of hard work and thorough planning and research. A scientific discussion with colleagues is not very credible because it involves the sharing of opinionated information, but it is certainly more reliable that the varying answers of school-aged peers.
The increase in the high fiber diet reduces the risk of colon cancer is suggested by the researchers. The effect of high fiber dietary intake add bulk to the digestive system.
