BANANA ALLERGY


Key Allergens

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

Bananas also contain other allergens including profilin proteins and lipid transfer proteins. Mus a 4 is a thaumatin protein, this is made by plants to inhibit fungal growth.

Associated Syndromes

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

In Pollen-Food Allergy Syndrome the body mistakes the shape of a protein that it is already sensitive to (a plant pollen) to a similarly shaped protein in certain fruits, vegetables, spices, herbs and nuts.

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.

You may have LTP Syndrome if you react to multiple foods in the cross reactivity section.

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.

Other foods containing thaumatin proteins are kiwi, chilli, peppers, apple, banana, cherry and peach.

If sensitised to LTP proteins you may also react to kiwi, strawberries, sunflower seeds, walnut, apple, mulberry, banana, pea, apricot, cherry, plum, almond, peach pomegranate, raspberry, tomato, grape, celery, peanut, asparagus, cabbage, broccoli, chestnut, lemon, tangerine, orange, hazelnut, lettuce, lentils, lupin, green bean, pear, mustard, wheat and maize.
