Peanut allergy rates fall by 43 percent

Peanut allergy rates among children under age three dropped by 43 percent over the last decade, according to a study released in October 2025. The findings suggest that earlier medical advice to keep peanut products away from young children may have been incorrect. Current research indicates that introducing peanut products to infants between four and six months old reduces the risk of developing a peanut allergy.

Dr. David Hill, the lead author of the study, identified the shift in medical guidance as a primary driver of the decline. He noted that the change in recommendations likely prevented many new 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,” Dr. Hill said.

Kristie Herring described the diagnosis of her son Parker as a “total surprise” despite their family history. Parker suffers from a severe peanut allergy and currently undergoes oral immunotherapy. This treatment involves slowly increasing doses of peanut protein, which has enabled him to consume peanut butter safely again. Herring said the change in guidance has been transformative for many families.

The American Academy of Pediatrics now recommends early introduction of peanut products for all infants without a history of prior reaction, provided they are already eating other solid foods. Pediatricians advise parents to start with small amounts and feed peanut foods at least twice a week during the first year and beyond. Experts warn that whole peanuts should never be given to infants due to the choking risk.

Specialists caution that early introduction is not a guaranteed cure for every child. Food allergy remains a complex condition with multiple causes. For children who have already developed a peanut allergy, specialists recommend consulting an allergist to discuss available treatment options. They also advise maintaining vigilance in managing the condition daily.

The study provides data on the effectiveness of the updated guidelines. The 43 percent reduction in cases represents a measurable change in public health outcomes for young children in the United States. The findings support the current recommendation to introduce allergens early in infancy rather than delaying exposure until later years.
