What carbs are a problem for people with irritable bowel syndrome?

ANSWER

Certain carbs called FODMAPs are a problem for people with irritable bowel syndrome (IBS). These carbs aren’t absorbed by the small intestine. When they hit the large intestine, they quickly break down and make gas. It happens to everyone, but it can be a problem for people with IBS.
