Does a low fibre with low residue diet reduce Crohn's symptoms?

Crohn's and Colitis Foundation of America, Diet and Nutrition
"About two thirds of people with small bowel Crohn's disease develop a marked narrowing (or stricture) of the lower small intestine, the ileum. For these patients, a low-fiber with low-residue diet or a special liquid diet may be beneficial in minimizing abdominal pain and other symptoms. This diet minimizes the consumption of foods that add "scrapy" residue to the stool. These include raw fruits, vegetables, and seeds, as well as nuts and corn hulls. The registered dietitian associated with your IBD treatment program can assist you in devising such a diet when appropriate. Often, these dietary adjustments are temporary; the patient follows them until the inflammation that caused the narrowing responds either to medical treatment or to a corrective surgical procedure."
