There are 13 allergens associated with allergy to kiwi, these are called Act d 1, Act d 2 to Act d 13.

Act d 1 is a cysteine protease protein.

Act d 8 is a Bet v 1 like protein associated with Pollen-Food Syndrome, so those allergic to this protein may suffer Oral Allergy Syndrome symptoms to a group of related foods.

Act d 9 is a profilin protein, these are panallergens found in many fruits and vegetables.

Act d 10 is a lipid transfer protein (LTP), these are also panallergens found in many foods, there is a big overlap with pollen foods and LTP foods, but allergy to LTP is associated with more severe allergic reactions.

Act d 11 is a kiwi protein which is a major latex protein/ripening-related protein and is therefore linked to latex allergy.

Act d 13 is a 2S seed storage albumin, these are usually found in nuts, seeds and legumes.

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

You may have Pollen-Food Allergy Syndrome if you suffer from kiwi allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.

Kiwi 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.

Allergy to kiwi is also associated with LTP Syndrome. Contact with the skin of the kiwi is associated with urticaria (hives), allergic contact dermatitis and asthma.

Some of the latex linked allergies are in foods which contain high levels of chitinase, like chestnuts, banana, avocados, papaya, pomegranate, corn (maize) and tomatoes.

If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, pear, peach, plum, nectarine, apricots, cherries, tomato, celery, carrot, potato, parsnip, pepper, dill, cumin, peas, coriander, Fennel, Hazelnut, Walnut, Almonds, peanuts, lentils and beans

Other foods containing cysteine protease are papaya, potatoes and melons.

Profilin proteins are also found in pineapple, celery, peanut, chilli, watermelon, orange, hazelnut, carrot, strawberry, soya, barley, walnut, lychee, lupin, apple, banana, dates, cherry, almond, peach, pear, mustard, tomato, aubergine and wheat.

Other food containing 2S albumin seed storage proteins are cashews, peanuts, almonds, mustard seed, rapeseed, turnip, chickpeas, hazelnuts, pistachio, buckwheat, soya beans, sunflower seeds, walnuts, peanuts, castor beans and sesame seeds.
