Bananas and FODMAP
(Last Updated On: April 26, 2021)

When it comes to the FODMAP diet, some products seem to be a little ambiguous. One of those products is bananas. You can, and can’t eat them. Easy right? So what’s the deal with FODMAP and bananas?

No worries, I’ll tell you exactly how it works.

What is the FODMAP in Bananas?

If you open the Monash University FODMAP app and search for bananas. You’ll quickly see that there are 5 different types listed. The ripe, unripe, dried and sugar banana in the ripe and unripe form. All of these have a different portion size you can eat during the FODMAP diet and the sugar banana contains a different FODMAP from the common banana, to make it even more complicated.

The ripe sugar banana contains fructose, whereas the common and dried banana contain Oligo-fructans. Depending on your food sensitivities, you can decide for yourself whether or not you will eat bananas, and which one you will choose.

How Much Banana Can You Eat on the FODMAP Diet?

As mentioned above, depending on your sensitivities, fructose or Oligo-Fructans, you can or can’t eat bananas. It all comes down to the ripeness of the banana whether or not you can eat more or less of it. If a regular banana is really ripe, a.k.a. has brown spots, just stay away from it. 35 grams is the upper limit of ripe banana you can eat, so that’s not that much.

If a regular banana is unripe, which means: not too green, maybe a little bit of green at the top, nicely yellow and no brown spots. Then you can eat 100g of it, which is a decent portion size.

Dried bananas, or banana chips, on the other hand, are also mostly a no-go. The upper limit is 30 grams, so if you really want them, you can weigh them for the right portion size.

The sugar bananas, as mentioned have a slightly different portion size. A firm sugar banana is low FODMAP up to 112 grams. And a ripe one is low FODMAP up to 56 grams. That is quite a difference!

How to Make Sure You Have the Right Ripeness of Banana

If you buy bananas, get 1-2 pieces to make sure they won’t ripen too much before you get the chance to eat them. It’s a waste to throw away bananas with brown spots.

One thing you can do to make sure you always have bananas is to freeze them. Buy a bunch of bananas which are exactly ripe, strip them from their peel as soon as you get home, put them in airtight containers and freeze them. This way the bananas won’t continue to ripen and won’t get a higher FODMAP content.
As soon as you want to use the bananas, just cut the frozen banana to a 100g size, and keep the rest of the banana in the freezer for another time.

This way you’ll always have bananas on hand to make a nutritious smoothie, or to make my recipe for healthy banana pancakes! Don’t let them defrost and try to eat them though! They become a sad (somewhat slimy) mess if they have been frozen before!

Really do make sure to get the peel off before you freeze the bananas, once they’re frozen the peel is really hard to get off! (And I speak from experience…)

How About Plantain?

Plantain is a completely different story. And good news! Plantain is low FODMAP and can be eaten freely. So if you want to bake or use a banana in a recipe, grab the plantain! A plantain tastes slightly different from a regular banana and is not as tasty when it’s raw. But in baking, it’s a great replacement for the regular banana.

  • I live on low food map i have a digestive disorder i cannot eat bananas bananas, i swell up i bloat i fill with gas i discovered the plantain chips.
    And you show they are better than bananas trying them for the first time today.

    • Sorry to hear you’ve been experiencing such bad symptoms from eating bananas. Let me know how the plantains went for you!

  • Do you know WHY plantains are low FODMAP? I fried them once, and they were pretty sweet. Is the sugar mostly glucose and sucrose?

    • Hi Emily, I’m not sure which sugars are exactly present in plantains but they have been tested by the Monash University and announced safe for the FODMAP diet, so it’s not fructose and/or fructans. Sweetness is not a problem for FODMAPs in general.
