The research, led by the Murdoch Children's Research Institute (MCRI) and to be presented at the American Academy of Allergy, Asthma & Immunology Virtual Annual Meeting this Sunday, also found a significant increase in parents introducing peanut into their babies' diet since the guideline changes. Introducing peanut early in a child's life has been shown to prevent peanut allergy during randomised controlled trials. But MCRI PhD candidate and study lead author Victoria Soriano said this research was the first to test the approach in homes and to analyse what impact the guideline changes have had on peanut allergies.
