Do certain foods make your mouth itchy? We may have the reason why!
In this episode, Dr. G and Kortney are joined by Dr. Wright, a board-certified allergist and Medical Director at Thermo Fisher Scientific, as they demystify cross-reactivity in food allergies.

- The cross-reactive pollens and their cross-reactive foods.
- The types of tests available for testing cross-reactive allergens: skin prick, blood test and component testing.
- How to determine if a food is an allergen due to pollen cross-reactivity or IgE mediated.
