Which dietary change is commonly advised for IBS?

• A. Avoid gas-producing foods such as bananas, cabbage, onions
• B. Eat gas-producing foods to relieve symptoms
• C. Avoid dairy completely
• D. Avoid all fiber

Answer: (A)

In IBS, a common approach is to reduce foods that produce a lot of gas in the gut, which helps lessen bloating and abdominal discomfort. These foods contain fermentable carbohydrates that aren’t absorbed well in the small intestine and are fermented by gut bacteria, creating gas and distension. That’s why avoiding items like the ones listed can often improve symptoms for some people.

Eating gas-producing foods to relieve symptoms would have the opposite effect, since it would increase gas production. Eliminating dairy completely isn’t necessary for everyone with IBS—many tolerate dairy fine, while others are lactose intolerant and may need to limit it. Avoiding all fiber isn’t recommended either; fiber can help some IBS patients, especially when you choose the right type and increase it gradually.
