A frustrating part of irritable bowel syndrome (IBS) is that it can’t really be treated — only managed through careful and deliberate lifestyle changes. Eating small and frequent meals, limiting certain foods, and managing stress can all improve IBS symptoms.

But an even more frustrating part of IBS is that the foods that trigger IBS symptoms are not so clear. A food can cause a riot in your colon one day, and be perfectly fine the next. As you try to figure out what’s “safe” and what’s not, each meal can feel like walking through a minefield. Enter: The low FODMAP diet. This dietary plan “helps manage symptoms of digestive distress — gas, bloating, pain, and alteration in bowel habit,” says Kate Scarlata, RDN, LDN, and author of The Low-FODMAP Diet Step by Step.
