Tips

Birch pollen allergy sufferers have allergic reactions to certain foods.

Cross-reaction occurs because many foods contain molecules that are similar to those found in birch pollen, which are recognised by the immune system also when ingested, thus triggering the reaction.

Birch has cross-reactivity with apple, peach, apricot, medlar, raspberry, strawberry, cherry, banana, walnut, hazelnut, almond, peanut, pistachio, carrot, potato, fennel, celery, parsley.
In general, OAS to apple and hazelnut is more common in birch allergy sufferers.
Less frequent, and almost always associated with apple and hazelnut allergy, is allergy to apiacae (celery, carrot and parsley).
