Double Trouble: Unpacking Nut and Sesame Seed Co-Allergy in Europe

In this episode, we dive into a groundbreaking European multicenter study that sheds light on the often-overlooked overlap between nut and sesame seed allergies. Why do so many children allergic to tree nuts also react to sesame? How can we accurately diagnose and define coexistent allergies through challenge-proven testing?

Join us as we unpack the methodology, clinical significance, and real-world implications of this important research. Whether you’re a clinician, researcher, or allergy-aware parent, this episode explores key findings that could influence future diagnostic pathways, dietary management, and allergen labelling policies across Europe and beyond.

Tune in to learn:

• The prevalence of coexistent sesame and nut allergies
• Why oral food challenges remain the gold standard
• How this study may influence allergen avoidance and food safety
