PEA ALLERGY


Key Allergens

There are 3 key allergens associated with pea allergy.

Pis s 1 and Pis s 2 are vicilin protein and convicilin proteins, also known as 7S seed storage proteins. These proteins are most commonly found in nuts, seeds and other legumes.

Pis s 3a lipid transfer protein (LTP), these proteins are panallergens which have the potential to cause allergic reactions across groups of different foods.

There has been an increase in the number of "free from" foods which are using pea protein as an ingredient to make dairy free and nut free foods. Additionally more people are choosing to eat vegan foods and these also may contain pea proteins as alternative high protein sources. Peanuts contain both 7S seed storage proteins and lipid transfer proteins, so those with a peanut allergy may also react to products containing pea proteins.


Associated Syndromes

You may be suffering from LTP Syndrome if you have reactions to various fruits, vegetables and nuts and your reactions continue to be severe after you have discarded the peel and have cooked the food.


Cross Reactivity

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.

7S seed storage proteins are found in various nuts and seeds, you may also react to cashew, pecan, hazelnut, buckwheat, soya beans, walnuts, lentils, lupin, macadamia nuts, sesame and mung beans.
