Did you know that up to 70% of adults with seasonal allergies may experience symptoms of pollen food allergy syndrome (PFAS)? This often-overlooked condition can mimic true nut allergies, leading to unnecessary dietary restrictions. In this episode, we tackle the challenge of differentiating PFAS from primary nut allergies. We explore the molecular basis of cross-reactivity between pollen and food proteins, discuss key diagnostic approaches using testing with allergen components, and provide insights on risk stratification. Learn about the unique presentation of pollen food allergy syndrome with tree nuts and peanuts, understand the role of labile versus storage proteins in symptom manifestation, and gain practical tips for patient management and dietary advice.
