Early Introduction of Allergenic Foods in Infants and Children

Abstract

Immunoglobulin E-mediated food allergies are a concerning health problem affecting 5.5% of children and 6% of adults in the United States. Nine foods cause 90% of food allergies, with milk, eggs, and peanuts most often linked to food allergies in infants and children. Prevention strategies have shifted from avoidance of foods to the early introduction of high allergenic foods. Evidence supports that the early introduction of peanuts can reduce food allergies. United States guidelines promote the optimal times for the introduction of high-allergen foods. Future research is required to ensure evidence-based best practices for patients and families.
