[Recommendation] Look at certain foods [Why] 
Nuts, raw fruit, and tomatoes were reported in one study to be problematic for people with Crohn's disease, though other reports have uncovered reactions to different foods. In one trial, people with Crohn's disease were asked which foods aggravated their symptoms.15 Those without ileostomies found nuts, raw fruit, and tomatoes to be most problematic, though responses varied from person to person, and other reports have displayed different lists.16 (Ileostomies are surgical passages through the wall of the abdomen into the intestine that allow the intestinal contents to bypass the rectum and drain into a bag worn on the abdomen.) People with Crohn's disease wishing to identify and avoid potential allergens should consult a doctor.
