Toddler peanut allergies down 43 percent

Peanut allergy rates in children under three have fallen by roughly 43 percent over the last ten years. A study released in October 2025 documents this steep drop, challenging the previous medical consensus that infants should avoid peanuts entirely.

Dr. David Hill, the study's lead author, attributes the improvement to a change in clinical guidance. For years, doctors advised parents to delay introducing peanut products. The new recommendation, adopted by the American Academy of Pediatrics, urges families to start feeding peanut products to infants as early as four to six months old. This shift applies to babies who are already eating other solid foods and have not had a prior reaction.

The change in advice has altered daily routines for many households. Kristie Herring, a parent in Wake County, noted that her son Parker's severe peanut allergy came as a "total surprise" despite their family history. Parker now undergoes oral immunotherapy, a treatment that involves consuming slowly increasing doses of peanut protein. This process has allowed him to eat peanut butter safely again.

Experts emphasize that early introduction is a preventive measure, not a guaranteed cure. Food allergies involve complex biological causes. While the new guidelines suggest starting small and feeding peanut foods at least twice a week during the first year, they also warn that whole peanuts remain a choking hazard for infants. Parents are advised to consult an allergist if a child has already developed an allergy.

Dr. Hill stated that the updated recommendations likely prevented allergies in tens of thousands of children. "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," he said. The data indicates that the timing of first exposure plays a measurable role in a child's long-term immune response.

The American Academy of Pediatrics continues to monitor these outcomes. Current guidance remains focused on regular consumption rather than single exposures. Pediatricians advise parents to maintain a consistent schedule of peanut intake to sustain the benefits of early introduction.
