PEACH ALLERGY


Key Allergens

Most people suffering oral allergy type symptoms to peach are thought to be sensitised to the protein Pru p 1, which is similar in shape to Bet v 1 which is a protein found in birch pollen. This can cause cross reactions with other fruit.

Pru p 2 is a thaumatin protein, this is made by plants to inhibit fungal growth.

Pru p 3 is a Lipid Transfer Protein (LTP), these proteins are resistant to heat and are found in many types of plants. Patients suffering from a more severe allergy to cooked fruit may be sensitised to this group of proteins.

Pru p 4 is a profilin protein, these proteins are considered to be panallergens and can cause issues over many groups of foods.

Associated Syndromes

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

You may be suffering from LTP Syndrome if you suffer allergic reactions from eating 3 or more foods mentioned in the cross reactivity section below.

Cross Reactivity

If sensitised to alder tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, peach, pear, parsley, celery, almonds and hazelnuts.

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

Common foods involved in LTP allergy include 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.

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

Other foods containing plant profilins are carrot, kiwi, pineapple, celery, peanut, chilli, watermelon, orange, hazelnut, melon, strawberry, soya, barley, walnut, lychee, lupin, apple, banana, date, cherry, almond, peach, pear, mustard, tomato, aubergine and wheat.
