Relationship between seasonal allergies and food allergies

This Scientific American article explores the relationship between birch allergies (a common tree pollen allergy) and some food allergies. Birch and many fruits and vegetables share a common protein that is the allegen in all these cases. The post illustrates this relationship on a map of the family tree of these plants and trees.

Studies have shown that treating the birch tree allergy with sublingual immunotherapy allergy drops like Pollenguard also eliminates the allergy to these foods.
