Overview

• The Pediatrics study attributes the decline to recommendations beginning in 2015 that encourage introducing peanut products in infancy.
• Researchers examined electronic health records from dozens of pediatric practices to compare food allergy diagnoses before and after the guidance, noting the sample may not represent all U.S. children.
• Declines tracked in the 0–3 age group followed the initial 2015 guidance for high-risk infants and the broader 2017 expansion to more families.
• The shift in guidance stemmed from the 2015 LEAP trial, which found early peanut introduction cut future allergy risk by more than 80% with benefits persisting into adolescence for many participants.
• Adoption remains uneven, with surveys indicating about 29% of pediatricians and 65% of allergists follow the 2017 advice, and overall food-allergy prevalence is still about 8% of children, including more than 2% with peanut allergy.
