FODMAPs are fermentable sugars (fructans, GOS, lactose, fructose, polyols) that can cause bloating and pain in sensitive people, especially with irritable bowel syndrome. The low FODMAP diet limits them for a while, then reintroduces them to find your tolerance. It is best followed with a doctor or dietitian.
The FODMAPs of each food add up. Several “green” servings in the same meal can go over the cut-off. FODMAP Scanner does the maths for you.
