POTATO ALLERGY


Key Allergens

There are 4 main allergens associated with potatoes. The main allergen in potato is the protein patatin (also known as sol t 1) which is thought to cause the majority of allergic reactions.

Patatin protein is very similar in shape to an allergen in latex called Hev b 7.

Sola t 3 is a cysteine protease protein.

Potato and sweet potato are not closely related but are both in the Solanales family of plants. Sweet potato is not considered to be cross reactive with latex, but is linked to food protein induced enterocolitis (FPIES).

Associated Syndromes

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

There may be some cross reactivity with potatoes, latex and other foods containing latex-like proteins. This is called Latex Food Syndrome.

Cross Reactivity

If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, kiwi, pear, peach, plum, nectarine, apricots, cherries, tomato, celery, carrot, parsnip, pepper, dill, cumin, peas, coriander, fennel, hazelnut, walnut, almonds, peanuts, lentils and beans.

If sensitised to grass pollen you may also react to melon, watermelon, tomatoes, oranges, potatoes and peanuts.

Foods linked to Latex Food Syndrome may have linked allergies to foods which contain high levels of chitinase like avocado, jackfruit, fig, avocado, banana, corn (maize), kiwi, papaya, pomegranate and tomatoes.

Other foods containing cysteine protease are potato, papaya and kiwi.
