Racial differences in timing of food allergen introduction

Abstract

Food allergy (FA) impacts 8% of children in the United States,1 with disease prevalence varying by race and highest rates observed among Black children.2,3 However, it is unclear what factors may underlie racial differences in prevalence. Racial differences in timing of food allergen introduction during infancy may influence FA development and disease manifestation. The National Institute of Allergy and Infectious Diseases released the Addendum Guidelines for the Prevention of Peanut Allergy in the United States in 2017 (PPA guidelines).
