This study is looking for people with Irritable Bowel Syndrome (IBS) to see if avoiding certain foods, identified by a skin patch test, can help reduce IBS symptoms. You would be skin patch tested for 80 different foods and food additives to see if you have an allergy. Based on these results, you would either follow a "True avoidance diet" (avoiding foods you're allergic to) or a "Sham avoidance diet" (avoiding randomly selected foods you're not allergic to) for 16 weeks. The main goal is to see how your IBS symptoms change after this diet. You can join if you are 18 or older, have IBS diagnosed by a doctor, or meet specific IBS criteria. The study is currently unclear on its recruitment status and plans to enroll 250 participants.
