Good to know
Bananas change as they ripen. Firm, slightly green bananas are lower in FODMAPs, while very ripe, spotty bananas contain more fructans. That is why bananas sit in the moderate group overall.
If bananas bother you, choose firmer ones and keep them to one per meal. Frozen firm banana slices are useful in smoothies, where they add creaminess without needing extra fruit.
Bananas on a low FODMAP diet
- Small amounts of bananas are usually fine during elimination, but larger servings move into high FODMAP territory.
- Avoid pairing them with other moderate or high FODMAP foods in the same meal, which is where stacking matters most.
- If they bother you, note them in a food diary and test them again during reintroduction.

Fructan: Fructans are chains of fructose found in wheat, garlic, onion and some vegetables. People can't fully digest them, so they reach the large intestine, where gut bacteria ferment them. Read more about high FODMAP foods to avoid with IBS.
