Are Bananas Gluten Free? Here’s What You Need To Know In 2024

A gluten-free diet usually allows for whole, unprocessed foods — as long as they are not the gluten-containing grains, wheat, barley, or rye. That gives you a lot of options. Unfortunately, some additives in otherwise gluten-free food can cause trouble for people with certain conditions like celiac disease.

Some people use fruits like bananas for weight loss or simply love them as part of their regular, gluten-free diet. But are bananas gluten-free? Yes — they’re naturally gluten-free foods. Let’s learn more.

Do Bananas Have Gluten?

No, bananas are naturally gluten-free.

Gluten^[1] is a protein present in grains like rye, triticale, wheat, or barley. If someone is gluten-intolerant and ingests gluten, they might experience bloating, diarrhea, constipation, brain fog, and dermatitis. More serious symptoms can include accelerated weight loss, stomach pain, nausea, and vomiting.

Gluten triggers intestinal damage in celiac disease. It might also cause inflammation and increased gut permeability, meaning that larger food molecules, viruses, or bacteria might be absorbed into the bloodstream. If you suffer from this type of affliction, going gluten-free is a wise choice. 

However, just because the popular fruit does not contain gluten, some folks following a gluten-free diet may still have trouble after eating it. Bananas possess lectin, another protein. Like in celiac disease, lectin might also sometimes trigger an autoimmune response.^[2] 

Another protein that bananas have is called chitinase, which may cause stomach pain and discomfort for people with gluten intolerance.

What About Other Fruits?

Whole fruits are naturally gluten-free. Since farmers grow and store fruits separately from gluten-containing grains like wheat, you can be sure that fresh fruit is gluten-free. However, that changes when fruits become dried and packaged, canned, or pre-prepared, such as in fruit smoothies. 

Read labels carefully when considering these products. If you want to prepare a smoothie with low-sugar fruits: keep in mind that gluten-containing ingredients might be listed as flavoring in protein powder or thickener on the labels of processed foods. The same goes for meal delivery, meal replacement bars, and fat burners. 

Are Bananas Good For Gluten Intolerance And Celiac Disease?

Even though bananas contain no gluten, they aren’t always devoid of allergens. For example, people with latex allergies^[3] may also be allergic to banana proteins. Therefore, it’s best to avoid bananas if you’re allergic to latex.

Some folks with irritable bowel syndrome, or IBS, may discover that they have a negative reaction to many fruits.^[4] Many doctors suggest IBS patients avoid gluten-containing foods or foods high in FODMAPs — fermentable carbohydrates. As bananas are low-FODMAP, they are usually on the safe-to-eat list. However, some people might react to the fiber in bananas.

What about celiac disease? Those with celiac disease^[5] should be fine eating bananas. However, those with non-celiac gluten sensitivity, IBS, or any trouble digesting fiber could have a bad reaction to bananas — albeit not due to gluten. 

Bananas contain the protein lectin,^[6] which might trigger an immune response in some, causing discomfort. Like gluten, this can damage the body by triggering an autoimmune response.^[2] Some studies have confused gluten and lectin allergies because of the similarity. Other banana proteins such as chitinase^[7] can also trigger an allergy to bananas.^[8] 

If you experience any of the following symptoms after ingesting banana, it might be a sign of an intolerance or allergy:

• Diarrhea.
• Stomach pain.
• Cramps.
• Nausea.
• Bloating.
• A lot of gas.
• Vomiting.
• Constipation.
• Skin flushing.
• Headaches.
• Palpitations.
• Mouth numbness. 
• Mouth tingling.

If eating bananas doesn’t agree with you, remove them from your diet temporarily. If your symptoms improve, you may want to eliminate them altogether. Rather than deal with gastrointestinal pain and abdominal discomfort, you may want to find another fruit to eat. 

How To Choose Gluten-Free Bananas

Choose bananas in their whole, natural form, and they will be gluten-free. Make sure they’re part of a balanced diet that includes vitamins.

Gluten-Free Alternatives To Bananas

Avocado

Avocado has a deep, nutty flavor and a creamy texture that people love to eat. They’re also versatile, used in both savory and sweet ways, making them different from other fruits.

Try avocados to replace bananas in juices or smoothies. You can also use it as a topping for peanut butter sandwiches or in snack bowls. Although avocados contain more fat than bananas, the upside is that they add richness and deep flavor.

Just keep the ratio of other ingredients the same when substituting a banana with an avocado. For example, if your recipe calls for a half-cup of banana, swap it for a half-cup of avocado. 

Apple Sauce

Banana is commonly used in desserts and sweet treats because of its flavor and binding properties. But you can also use apple sauce as an alternative to bananas in many recipes, such as banana cream pie. 

This popular treat can be served in more than one way, including both savory and sweet dishes. Foodies love this staple’s sweet-tart flavor and smooth, enjoyable texture. It just naturally goes great with lots of different ingredients.

When you use apple sauce, just make sure you use it in adequate amounts. Add a bit of nutmeg or cinnamon for a more delicious flavor.

Apple sauce is also a great option used as a gluten-free binding agent or healthy sweetener in baked goods. Experiment and find ways to enjoy this tasty treat.

Sweet Potatoes

If your stomach can’t handle mashed bananas, try mashed sweet potatoes for a creamy, smooth, and naturally sweet alternative. You’ll notice the consistency is similar, with the bonus being that sweet potatoes aren’t as starchy.

Most people enjoy a sweet potato’s fluffy and light texture. Keep in mind the difference in flavor between the two. A mashed sweet potato is slightly less sweet than a mashed banana, with a light and earthy flavor.

Use a one-to-one ratio when substituting mashed sweet potatoes for bananas in a recipe. If your recipe requires two cups of mashed banana, use two cups of mashed sweet potatoes instead.

Plantains

Plantains often get confused for bananas, but they’re not the same. Substitute plantains, and you might not have similar tummy troubles. Plantains are often used in recipes, adding a starchiness and mild flavor that won’t add any extra sweetness.

Their firm texture is more akin to potatoes than bananas. Fry them and use them as a side dish, or mash them and use them instead of potatoes. Due to their slightly bland taste, be sure to add some sugar, honey, or herbs, depending on what you’re making.

Conclusion

Bananas do not have gluten and are naturally gluten-free. However, some people may still react poorly to the proteins or fibers in bananas. So they might still cause stomach problems for some — especially for those with IBS and similar conditions. 

If you have any gut conditions, consult your doctor. Sometimes it’s best to eat bananas in moderation or eliminate them. You can also enjoy several great substitutes for bananas. Avocados, applesauce, plantains, and mashed sweet potatoes have a similar texture or flavor, enhancing the overall taste of most dishes and avoiding banana-induced gastrointestinal issues. Experiment to find whatever works best for you.
