How fiber reduces the risk of colorectal cancer
There are many conflicting opinions on whether fiber in the diet has a reducing effect on colorectal cancer. This position has been challenged by some researchers who have argued that fiber does not prevent colorectal; cancer in any way. In this paper, I will discuss how fiber prevents colorectal cancer.
The fiber plays an important role in adding bulk to the waste. The bulky waste spends less time in the digestive system, and since they contain some carcinogens, they are eliminated with ease. The quick elimination prevents the cells to be affected by the carcinogens (Aune, et al., 2011). Additionally, the breakdown of fiber by the bacteria releases butyrate that is a chemical substance that prevents the growth of tumor in the colon (Ferguson & Harris, 1999). The presence of fiber in the diet reduces the concentration of carcinogens in the digestive system (Rattue, 2011).
Not all foods are associated with fibers that are associated with the reduction of colorectal cancer.

There is evidence indicating that fiber reduces the risk of collateral cancer. Fiber also reduces the risk of other diseases such as constipation and irritable bowel syndrome. The fibers that reduce the chances of colorectal cancer are found in cereals.
