Until more research emerges, current evidence suggests that following a low-FODMAP diet and limiting certain high-fiber, high-carb foods may help some people with IBDs like UC feel better.
- Almond milk (plain, unsweetened)
- Red and yellow bell peppers
- Carrots
- Certain cheeses, such as cheddar, Swiss, Parmesan, brie, feta, mozzarella, American, and queso fresco
- Citrus fruits (except grapefruit)
- Cucumbers
- Eggplant
- Grapes
- Green beans
- Potatoes
- Tomatoes
“This diet is not very restrictive, since there is a wide spectrum of foods to choose from, and is fairly easy to follow,” says Shen, who likes to tell people, “It’s not no FODMAP, just low-FODMAP.” For example, certain foods, such as apples, can be made diet friendly by peeling them.
There’s also little risk in trying the diet in the short-term, though it’s a good idea to work with a registered dietitian to make sure you’re getting all the nutrients you need in your diet and carrying out all phases of the diet, including elimination (temporarily removing certain foods from your diet) and reintroduction (reintroducing those foods into your diet after the elimination phase), correctly. You are still able to get all the nutrients your body needs, including fiber. “Even a low-FODMAP diet still has some fiber,” Shen says.
Overall, following a low-FODMAP diet can be an effective way to learn more about what triggers your UC flares, relieve uncomfortable symptoms, and improve the gut microbiome.
