Foods to avoid with Inflammatory Bowel Disease (IBD)
With Crohn's disease and ulcerative colitis, sensitivities centre on the gut lining itself: emulsifiers, additives like titanium dioxide, fermentable carbohydrates and lactose are the usual suspects. Tolerance often shifts sharply between an active flare, when low-residue and low-FODMAP choices help, and remission, when many foods can return.
