Dietary fiber is the indigestible portion of plant foods having two main components: soluble (prebiotic, viscous) fiber that is readily fermented in the colon into gases and physiologically active byproducts, and insoluble fiber that is metabolically inert, absorbing water as it moves through the digestive system, easing defecation.
It acts by changing the nature of the contents of the gastrointestinal tract and by changing how other nutrients and chemicals are absorbed. Soluble fiber absorbs water to become a gelatinous, viscous substance and is fermented by bacteria in the digestive tract. Insoluble fiber has bulking action and is not fermented. Lignin, a major dietary insoluble fiber source, may alter the fate and metabolism of soluble fibers.
Despite the many positives of fiber in one's diet the foods are often difficult to digest and Crohn's and colitis patients are often put on diets to minimize these difficult to digest, fiber filled foods. When you are on a low residue fiber diet, you will eat low-fiber foods that are easy for your body to digest. Eating these foods may slow down your bowel movements.
This diet can include foods you are used to eating, like cooked vegetables, fruits, white breads, and meats. It does NOT include foods that make your bowels work more, like beans and legumes, whole grains, many raw vegetables and fruits, and nuts and seeds.
