Fiber decreases the transit time through the intestine. Cancer of the colon can be attributed to a lack of dietary fiber. Animal products do not have any fiber so their passage through the intestine is slow. The proteins ferment and allow harmful bacteria to multiply within the colon. The harmful bacteria secrete carcinogenic waste as a by-product that damages the intestine.
Nutritionists recommend a salad with a meal high in meat or dairy products.
The fiber in vegetables slows down fermentation and neutralizes some of the toxins in the bowel. It is important to break a fast with fruits and vegetables. Their high fiber content acts like a cleaning sponge within the intestine. Although fiber is important for a healthy diet and a clean colon, during fasting, fiber slows down the healing process. It causes the digestive system to work.
