QUINOA ALLERGY


Key Allergens

Quinoa is a plant in the Amaranthaceae family of plants. This family of plants also includes spinach, sugar beets and chard. Quinoa is often thought as a cereal, but is in fact the dried seed of the Chenopodium plant.

As it is NOT a cereal it doesn't contain any gluten, so is suitable for consumption by coeliacs.

The World Health Organization (WHO) does not have any recorded allergens for quinoa, but it is thought to contain 2S seed storage proteins, 7S seed storage proteins and 11S seed storage proteins. These are proteins more commonly found in nuts, seeds and legumes than in grain. More research is being done to see if quinoa also contains profilin and oleosin proteins.

The seeds are naturally covered by a saponin, which has a bitter taste and protects the plant from being eaten by birds and insects. It is easily removed with washing.


Associated Syndromes

Allergy to quinoa has not been linked to any allergic syndromes at this time.

Cross Reactivity

Foods containing 2S seed storage proteins are peanuts, cashews, brazil nut, mustard, pecan, hazelnut, soya beans, walnut, pistachio, sesame, almonds, kiwi, turnip, pumpkin and sichuan pepper. 2S seed storage proteins are also found in rapeseed, buckwheat, flaxseed, castor beans, mung bean, chickpea, sunflower seeds and pine nuts.

Other foods containing 7S seed storage proteins include peanuts, cashews, pecan, hazelnut, soya beans, walnut, pistachio, macadamia nuts, sesame, lupin, coconut, mung beans and peas. 7S seed storage proteins are also found in buckwheat and lentils.

Other foods containing 11S seed storage proteins include almonds, brazil nuts, cashews, hazelnut, macadamia nuts, mustard, peanuts, pecan, pistachio, sesame, soya beans, walnuts, kiwi and pumpkin. 11S seed storage proteins are also found in sunflower seeds and hemp seeds.

Profilin proteins are also found in celery, peanut, soyabeans, walnut, lupin, almonds, mustard, hazelnut, kiwi, pineapple, chilli, melon, orange, strawberry, lychee, apple, banana, aubergine (eggplant), peach, pear, tomato, dates, cherry, carrot, barley and wheat.

Peanuts, hazelnut, buckwheat and sesame seeds all contain oleosin proteins.
