Banana Allergy

Key Allergens

Allergic reactions from eating bananas is thought to be caused by chitinase, which is a plant derived enzyme made by the plant naturally to act as a defence against fungal attacks.


Banana allergy is most often seen in conjunction with allergies to other foods, either presenting as Pollen-Food Allergy Syndrome or Latex Food Syndrome.

Latex Food Syndrome is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.

Cross Reactivity

Those with a sensitivity to chitinase may have linked allergies to foods which contain high levels of chitinase, like avocado, chestnuts, corn (maize), kiwi, papaya, pomegranate and tomatoes.

If sensitised to Ragweed pollen you may also have problems with Melon, Courgette, Cucumber, and Squash

45% of latex allergy sufferers are also allergic to bananas.
