Emerging research indicates that a low-FODMAP diet, which involves limiting high-fiber and high-carbohydrate foods, could potentially alleviate symptoms for individuals with inflammatory bowel diseases (IBDs) like ulcerative colitis (UC).

A typical low-FODMAP diet involves restricting certain foods. Some foods to limit or avoid include:

• 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

However, many foods are acceptable on a low-FODMAP diet.

Navigating the Low-FODMAP Diet

“This diet is not very restrictive, since there is a wide spectrum of foods to choose from, and is fairly easy to follow,”

“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 clarifies, “It’s not no FODMAP, just low-FODMAP.” She suggests that peeling certain fruits, like apples, can make them suitable for the diet.

According to SHEN, there is minimal risk associated with trying the diet in the short term. However, she advises consulting a registered dietitian to ensure adequate nutrient intake and proper execution of all diet phases, including elimination and reintroduction. She emphasizes that a low-FODMAP diet can still provide necessary fiber. “Even a low-FODMAP diet still has some fiber,” SHEN says.

Ultimately, a low-FODMAP diet can help identify UC flare triggers, alleviate discomfort, and enhance the gut microbiome.
