The correct answer is "fiber".
Fiber is actually indigestible food products such as cellulose that aids in the digestion and bowel function. Fiber, first of all, limits the absorption of extra fats therefore preventing hypertriglyceridemia and eventually cerebrovascular and cardiovascular consequences. Fiber also limits glucose absorption controlling type II diabetes. Lastly, fiber also acts as protection in the colon by increasing the transit times of potentially carcinogenic substances found in food, therefore preventing colon cancer.
