Early introduction of peanut products is translating into fewer allergies in young children, new research shows. An analysis of electronic health records from dozens of pediatric practices found peanut allergy diagnoses in ages 0 to 3 fell more than 27% after 2015 guidance and over 40% after recommendations expanded in 2017—an estimated 60,000 children avoided allergy. While overall food allergies continue to rise, the study’s authors and a commentary called the trend promising, even as adoption of the guidance has been uneven and the data may not represent all U.S. pediatric patients.
