High Fiber Diet

Function of the Colon

The main job of the colon is to complete the digestion process. This occurs by removing excess water from food wastes entering from the small intestine. When wastes pass through the intestines too quickly, not enough water is absorbed and watery stools and diarrhea are the result. In contrast, if the passage of waste is too slow, too much water is absorbed. This results in hard stools and constipation, which often leads to straining.

The Importance of Dietary Fiber

Fiber promotes the wavelike contractions that keep food moving through the intestines. Fiber passes through the intestine undigested. It also absorbs many times its weight in water, resulting in softer, bulkier stools. This usually results in the stool passing through the bowel easily and quickly. In this manner, it is believed that harmful substances are swept out of the digestive tract before they can cause problems. A softer, larger stool can help prevent constipation and straining. This can help avoid or relieve hemorrhoids. More bulk means less pressure in the colon, which is important in the treatment of Irritable Bowel Syndrome (IBS) and Diverticulosis.  In addition, fiber appears to be important in the treating diabetes, elevated cholesterol, colon polyps and cancer of the colon.
