Can introducing peanuts early prevent allergies? Real-world data confirms it helps

Using data from over 120,000 U.S. children, this Pediatrics study found that the prevalence and risk of peanut and other IgE-mediated food allergies declined significantly after the 2015 and 2017 guidelines promoting early allergen introduction. The findings support these policies as effective public health measures to prevent food allergies in real-world settings.
