29 May 2024 --- Amid rising peanut allergy rates in Western countries, a study finds that regularly feeding peanuts to infants up to five years old reduced the rate of allergy in adolescence by 71%. The new research on longer-term allergy prevention builds on the Learning Early About Peanut Allergy (LEAP) clinical trial. “Decades of advice to avoid peanuts has made parents fearful of introducing peanuts at an early age. The evidence is clear that early introduction of peanuts in infancy induces long-term tolerance and protects children from allergies well into adolescence,” says lead researcher Gideon Lack, professor at King’s College London, UK.
