How dietary landscapes impact food allergy

Diets and environments are critical determinants for food allergy development. Harnessing unprecedented epidemiological and nutritional data, we examined the overall dietary environments for common food allergens and their intrinsic nutrient composition. We found that food and macronutrient supplies minimally impacted food allergy prevalence, but higher protein and glycine in food allergens correlated with less allergies. These findings offer new directions in food allergy research and management. ### Competing Interest Statement LM is a current employee of the Translational Science Hub Global Sanofi Vaccines R&D Brisbane, Australia.
