Banana allergy and intolerance

Banana allergy and intolerance

It’s banana intolerance time! Bananas are a wonderful fruit and so versatile. We use them in numerous ways every day. Unfortunately, it’s not uncommon for banana intolerance to occur, and it can also be a severe allergy for some people. It is commonly connected to an allergy or intolerance to latex, which is due to a protein in bananas that mimics that found in the rubber trees that produce latex. There are a group of other foods related to this too, and collectively it’s called ‘latex food syndrome’. Read on to learn the risk factors, most common symptoms of banana allergy and intolerance, what it’s related too and what you can do about it.

Risk factors for developing banana intolerance

  • Having a family history of food allergies or intolerances
  • Rubber or latex allergy
  • Nut allergy or intolerances
  • Digestive disorders

What does a banana have to do with latex?

So as we mentioned earlier, bananas have a similar protein to one found in the rubber trees that produce latex. This is why a person with a latex allergy or intolerance may also react to bananas. Bananas, however, are not the only plant with similar proteins to rubber trees. Other foods that may also cause an issue are:

  • Kiwi fruit
  • Avocadoes
  • Chestnuts

When people react to these foods, it’s called ‘latex food syndrome’. Avoid these foods if you have a banana or latex reaction.

Symptoms of Banana Allergy

Remember that food intolerance is NOT life-threatening, whereas a food allergy IS. If what you have is a banana allergy, your symptoms could be any of the following:

  • Hives
  • Itching
  • Swelling of mouth, tongue, lips and airways
  • Stomach cramps that can be quickly followed by diarrhoea
  • Fever
  • Difficulty breathing
  • Anaphylaxis


These symptoms are life-threatening and need to be addressed by a doctor immediately. 

People with a banana allergy don’t actually have to eat the banana for the above symptoms to occur. Simply touching the fruit can be enough to cause severe symptoms. 

Symptoms of banana intolerance:

Like all food intolerances, the symptoms are somewhat similar but can vary between individuals. For the following symptoms to occur, a person has to actually eat a banana. The symptoms don’t always develop immediately and can take up to 48 hours to manifest fully.

  • Skin rashes

What can you do about banana intolerance?

In summary, we have had a look at banana intolerances and allergies today. We learnt that banana allergies often go hand in hand with latex allergies due to a protein from the rubber tree. Bananas contain a remarkably similar protein, hence the allergic reaction in susceptible people. 

We covered the most common symptoms of banana allergy and those of banana intolerance. We also looked at the best options if you suspect a banana intolerance. The first step when you suspect any food intolerance is to order a food intolerance test. You can do so HERE. Our hair test is noninvasive and has a quick turn around time, which means that you can get on the road to symptom resolution as quickly as possible.


Today we have looked at what a strawberry allergy and a strawberry intolerance is. We learnt that a strawberry allergy can happen from touching or eating a strawberry and that it can take just minutes for it to occur. If you have an allergy to strawberries, you might also react to other fruits of the same family or foods and items that contain a similar protein to strawberries. 

We compared the symptoms of a strawberry allergy to those of a strawberry intolerance. We then looked at how you can test for a strawberry intolerance with our simple at-home test, which you can order HERE. This test allows you to find out if you are intolerant to strawberries, as well as 500 other possible intolerances!
