PASSION FRUIT ALLERGY
Passion fruit is an edible fruit in the Passifloraceae
family of plants. They can be red, yellow, green or purple in colour.
The World Health Organization (WHO) has not formally added any specific allergens to their allergen nomenclature database for passion fruit, but there have been studies which show the fruit contains both chitinase
proteins. These are both proteins associated with latex allergy.
Passion fruit is a low FODMAP food. FODMAP
stands for F
olyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.
Passion fruit is also a food low in salicylates
. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as food intolerance symptoms in people who are sensitive to salicylates.
You can read more about Food Intolerances
on the dedicated Food Intolerance Page.
The plant involved in latex allergy Hevea brasiliensis
, the rubber tree plant, has an allergen called Hev b 11 which is a chitinase protein. Those very sensitised to latex may have a contact allergic reaction from foods, plants or insects containing similarly shaped proteins. This gives this protein an important role in Latex Food Syndrome
Chitinase proteins are found in avocado, banana, cashews, chestnuts, corn, grape, kiwi, mango and pomengranate.
Hevein proteins are found in apricot, avocado, banana, buckwheat, dill, goji berry, plantain, potato, swede and turnip.
