Early Peanut Introduction Linked to Notable Allergy Reduction in Children
A recent study indicates that recommending the early introduction of peanuts to infants has perhaps prevented peanut allergies in approximately 60,000 children. The research, stemming from the landmark LEAP (Learning Early About Peanut Allergy) trial, demonstrated a greater than 80% reduction in the progress of peanut allergies, with protection persisting in roughly 70% of children into adolescence.
Following the study’s findings, new guidelines were issued calling for the early introduction of peanuts.However, adoption of thes recommendations has been gradual. Surveys reveal that only about 29% of pediatricians and 65% of allergists reported adhering to the expanded guidelines issued in 2017.
Initial hesitation stemmed from confusion and uncertainty regarding the best methods for early peanut introduction, and concerns about replicating clinical trial conditions outside of a controlled environment. A commentary accompanying the study noted the data originated from a subset of medical centers and may not fully represent the entire U.S. pediatric population.
Despite these limitations, the authors concluded the research offers “promising evidence that early introduction of allergens is not only being adopted, but might potentially be having a measurable impact.”
Food allergy advocates have welcomed the increasing acceptance of early peanut introduction. “This research reinforces what we already know and underscores a significant opportunity to reduce the incidence and prevalence of peanut allergy nationwide,” stated Sung Poblete, executive director of Food Allergy Research & Education (FARE).
Current guidelines, updated in 2021, recommend introducing peanuts and other major food allergens between four and six months of age, without prior screening or testing. Parents are encouraged to consult with their pediatricians for guidance.
“It doesn’t have to be a lot of food, but small tests of peanut butter, milk-based yogurt, soy-based yogurts and nut butters,” explained Dr. Hill. “These are really good ways to allow the immune system to be exposed to these allergenic foods safely.”
Tiffany Leon, a registered dietitian and director at FARE, successfully introduced peanuts and other allergens early to her own children, ages four and two. Initially, her mother questioned the advice, but Leon explained the evolving scientific understanding.
“As a dietitian, I apply evidence-based recommendations,” Leon said. ”So when someone told me,’This is how it’s done now,these are the new guidelines,’ I just thought,well,this is what we’re going to do.”
