Peanut allergy rates in toddlers fall by 43 percent in ten years

Medical guidance for infant feeding changed a decade ago, and new data suggests the shift worked. A study released in October 2025 found that peanut allergy rates in children under age 3 have dropped by roughly 43 percent over the last ten years.

Researchers previously advised parents to avoid peanut products for young children to prevent allergic reactions. The new findings indicate that this approach may have been counterproductive. Introducing peanut products to infants between 4 and 6 months old appears to lower the risk of developing a peanut allergy.

Dr. David Hill, the lead author of the study, identified the reversal in medical advice as a major driver of the decline. He noted that the change in recommendations likely prevented many cases. “It’s safe to say in all likelihood, there are tens of thousands of kids today that don’t have food allergy that may have if we hadn’t made these recommendations about early allergen introduction,” Hill said.

The American Academy of Pediatrics now recommends early introduction of peanut products for all infants without a history of prior reaction. This guidance applies to infants who are already eating other solid foods. Pediatricians advise starting with small amounts and feeding peanut foods regularly, at least twice a week, through the first year and beyond. Doctors warn that whole peanuts should never be given to infants due to the risk of choking.

For families who already face a diagnosis, the condition remains complex. Kristie Herring, whose son Parker suffered from a severe peanut allergy, described the diagnosis as a “total surprise” given their family history. Parker is currently undergoing oral immunotherapy. This treatment involves slowly increasing doses of peanut protein and has allowed him to safely consume peanut butter again.

Experts caution that oral immunotherapy carries risks and that early introduction is not a guaranteed cure for everyone. Food allergy has multiple causes. Specialists recommend that parents whose children have already developed a peanut allergy consult an allergist about available treatment options and maintain vigilance in managing the condition.
