Do bananas cause bloating?

Short answer

Ripeness and portion change the answerA firm banana tends to sit better than a large, spotted one for people who react to fructans. Smoothie-sized portions can stack the dose.
FODMAP readPortion dependent

Firm banana is the lower-FODMAP choice; ripe, large servings can carry more fructans.

01

Two ways it can happen

  1. 01

    The carbohydrate profile changes as a banana ripens, so two bananas with the same name can produce different results.

  2. 02

    Smoothies combine a large fruit dose with milk, yogurt or protein powder, which adds more suspects.

02

Portion changes the test

One small, firm banana is a cleaner starting point than two ripe bananas blended into a shake.

03

Run a clean meal test

Try half to one firm banana on its own. On another day, test the ripe version at the same time and portion.
