“What to avoid if you have IBD?”

I'm not sure if this question is related to food specifically. There is some data that a Mediterranean diet is beneficial for IBD. Otherwise, a healthy diet with more fruits and vegetables, and less red meat and refined sugars are recommended. However, if someone is in an active IBD flare or if someone with Crohn's disease has any strictures in their intestines, then a low-residue diet is recommended (avoid raw veggies and fruits with skins).In addition, patients with IBD should avoid NSAIDs if possible (ibuprofen, Naprosyn, Advil, Aleve), as NSAIDs can aggravate IBD symptoms and potentially cause a flare.
