In the early 2000’s pediatricians recommended delaying the introduction of highly allergenic foods, like peanut, but we saw that the rates of peanut allergy continued to rise. However, the 2015 LEAP trial showed that early introduction was better. In fact, the LEAP trial found an 81% decrease in peanut allergies by age 5 in children who had an early introduction. In this episode, Stanislaw J. Gabryszewski, MD, PhD, discusses what we have learned in the decade since the LEAP trial and explains his recent study on how these guidelines have impacted the rates of peanut allergies in children.
