Banana FODMAP Content

Banana FODMAP content varies between different ripeness stages and different types of this fruit. So, we understand it might be tricky to include bananas in your diet if you are an IBS sufferer.

This article will discuss low FODMAP portions of bananas, their nutrient content, and some delicious low FODMAP banana recipes.

A firm banana is considered a low FODMAP fruit. As per Monash, it is low FODMAP at 100 g, which is roughly one small banana. Larger quantities are not suitable for the low FODMAP diet due to the presence of fructans (1).

A firm banana contains between 70-80 % resistant starch. During ripening, enzymes convert resistant starch into simple sugars. A ripe banana can contain less than 1 % resistant starch (2).

You can enjoy bananas in many different ways. You can add them to the following:

Low FODMAP yogurt
Low FODMAP porridge
Low FODMAP smoothie
Low FODMAP dessert

When bananas are ripe, the fructan content increases greatly. Therefore, a ripe banana is low FODMAP in a much smaller portion size of 35 g (1).

Sugar banana FODMAP content

Sugar bananas, also known as lady finger bananas, are low FODMAP when firm and ripe (1).

This type of banana is smaller than “common” bananas and have thinner skin. They also taste sweeter.

This type of banana can be eaten fresh or cooked. They can be added to dishes in the same ways as common bananas. When following a recipe, swap common bananas with sweet bananas.

Plantain FODMAP content

Plantain or cooking banana is a staple food in most regions of Africa and Asia. Plantains are starchy fruit with natural flavour. When cooked, the texture becomes softer, which is why plantains are usually eaten processed (3).

According to Monash, plantain is low FODMAP, meaning you can consume it freely (1).

Plantains are larger and usually less sweet than common bananas. You can enjoy plantains cooked or baked, sweet or savoury. You can follow the next low FODMAP recipes if you need some inspiration.

Are banana chips low FODMAP?

Banana chips are low FODMAP in small amounts – roughly 15 chips (1).

Banana chips are simply made from dehydrated bananas. Larger quantities are not suitable for a low FODMAP diet due to fructans, a type of FODMAP (1).

Banana chips are commonly present in breakfast cereals. Here, you can check our article on how to choose low FODMAP cereals.

Do bananas cause bloating and gas?

Yes, bananas can cause bloating and gas in some people that are sensitive.

Firm bananas contain a lot of resistant starch, which we are unable to digest. Therefore, when it reaches the large bowel, it is fermented by the gut microbiota, releasing gases. This can exacerbate symptoms like bloating and excess gas in people with IBS.

You might wonder how a ripe banana causes the same symptoms if enzymes convert resistant starch into sugars. Resistant starch is converted into sucrose, fructose, and glucose. Both sucrose and fructose can cause the same symptoms as resistant starch.

The solution is the same as for firm bananas – try smaller portions and gradually increase them and find your tolerance level.

Furthermore, ripe bananas can cause bloating and gas in people with IBS due to fructans. If you are sensitive to fructans, you should stick to the low FODMAP portion sizes, as discussed above (1).

Besides ripe bananas, fructans are also found in (1):

Onion
Asparagus
Wheat
Barley

This does not mean you have to avoid bananas completely, and is fact a good sign that we are feeding out gut bacteria! But to avoid or reduce symptoms, try smaller portions or spreading your intake across the day.

Banana’s Nutrition Facts

Now that we have discussed low FODMAP portions let’s find out its nutrition facts.

Firm banana at 100g provides us roughly (3):

3 g of dietary fibre (10 % of recommended intake)
360 mg of potassium (10 % of daily needs)
0,4 mg of vitamin B6 (33 % of daily needs)
9 mg of vitamin C (22 % of daily needs)

This makes bananas great fruit as a snack, or you can add them to:

Breakfast cereal
Porridge
Smoothie

Summary

Banana FODMAP content increases as the fruit ripens.

So, if bananas make you gassy and bloated, start by trying out smaller portions and gradually increase them to establish your tolerance.
