Peanut Allergy Prevention: Does Early Exposure Stick? Insights from LEAP-ON & LEAP-TRIO

In this episode, we explore the groundbreaking LEAP-ON and LEAP-TRIO studies — follow-ups to the landmark LEAP trial that showed early peanut introduction in infants at high risk for allergy can dramatically reduce the development of peanut allergy. But does the benefit last if peanuts are later avoided? Join us as we unpack the latest research on the durability of early allergen exposure, why it matters for families and clinicians, and what it means for allergy prevention strategies worldwide. Whether you’re a parent, healthcare professional, or just curious about food allergies, this episode offers practical insights, expert explanations, and the science behind one of the most influential allergy studies of our time.Sources:Du Toit, G., Sayre, P.H., Roberts, G., Sever, M.L., Lawson, K., Bahnson, H.T., Brough, H.A., Santos, A.F., Harris, K.M., Radulovic, S., Basting, M., Turcanu, V., Plaut, M. & Lack, G.
