Peanut allergy rates drop sharply

Peanut allergy rates among children under age 3 have fallen by roughly 43 percent over the last decade, according to a study released in October 2025. The findings suggest that changing medical advice to encourage early exposure may be the primary driver of the reduction.

The study indicates that introducing peanut products to infants between 4 and 6 months old reduces the risk of developing an allergy. This approach contrasts with previous medical guidance that recommended avoiding peanut products for young children. Dr. David Hill, the lead author of the study, identified the shift in guidance as a major factor in the declining rates.

Dr. Hill said, “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.”

For families who already faced a diagnosis, the change in guidance offers a different path. Kristie Herring is the mother of Parker, a boy who suffered from a severe peanut allergy. Herring said the diagnosis was a “total surprise” despite their family history. Parker is currently undergoing oral immunotherapy, a treatment that involves slowly increasing doses of peanut protein. This process has allowed him to safely consume peanut butter again.

The American Academy of Pediatrics now recommends early introduction of peanut products for all infants without a history of prior reaction. Pediatricians advise starting small and feeding peanut foods at least twice a week through the first year and beyond. The guidelines specify that infants must already be eating other solid foods before beginning this process. Whole peanuts should never be given to infants due to the risk of choking.

Experts caution that early introduction is not a guaranteed cure for every child. Food allergy remains a complex condition with multiple causes. Specialists recommend that families whose children have already developed a peanut allergy consult an allergist about available treatment options and maintain vigilance in managing the condition.
