What to eat during a Crohn's or ulcerative colitis flare. This is a grocery list and various meal ideas that are mostly autoimmune paleo (AIP) compliant and specific carbohydrate diet (SCD) compliant. The foods are compiled from several Crohn's and colitis patients. Everyone is different, so foods that work for one person may not work for another during a flare. These foods are also great for IBS flares, stomach viruses, and bloating.
