Banana (firm)
Usually low FODMAPWhy this food shows up for IBS
Ripeness changes this fruit's chemistry: green or firm bananas carry more resistant starch, which ferments in the colon and can trigger bloating, while ripening converts much of that starch into simple sugars. Fully ripe, spotty bananas are generally better tolerated at moderate portions.
