AVOCADO ALLERGY


Key Allergens

The main allergen found in avocado is called Pers a 1, this is a chitinase, which is a plant derived enzyme made by plants naturally to act as a defence against fungal attacks.

Associated Syndromes

Avocado allergy has been linked to Latex Food Syndrome, which is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.

Avocado allergy has also been linked in recent years to FPIES - Food Protein Induced Enterocolitis Syndrome.

Cross Reactivity

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