Balanced Diet (Fiber): Why we need to eat a abundant of Fiber foods?

Fiber-rich foods

Fiber-rich foods may work against colon cancer in a number of ways. Fiber attracts water, thereby diluting potential cancer-causing agents and speeding their removal from the colon. 

Also, many fiber-rich foods supply the vitamin folate, and diets rich in folate correlate with low rates of colon cancer. Another possibility involves the intestine’s resident bacteria. In fiber-rich intestinal contents, feasting bacteria reproduce rapidly, and in doing so, they bind nitrogen and carry it out of the body in the feces.

Nitrogen is a suspected contributor to cancer causation. Additionally, the colon’s bacteria ferment soluble fibers, forming the small fat molecules, which activate cancer-killing enzymes and reduce inflammation in the colon.
