Dietary fiber comes from plants and grains. Dietary fiber is not digested by the stomach or small intestine, but arrives unchanged in the colon where it has two main benefits: promoting regularity and providing nourishment for beneficial bacteria. Fiber in plant foods like vegetables, fruits, and grains can retain its density in the digestive tract and promote bulkier stool, which in certain medical circumstances, is not beneficial for all patients.
For certain medical conditions like diverticulitis, or after surgical procedures, it may be necessary to restrict the amount of dietary fiber taken in by the body to ease stress on the digestive tract. Intestinal surgery, post-colostomy, narrowing of the bowel, or an inflammatory disease are all situations where a physician might recommend a low fiber diet. Low fiber diets usually contain less than 10-15 grams of fiber per day and are rarely permanent. Patients usually are able to add more fiber back into the diet after an appropriate healing time.
