Old advice delayed peanuts, raised risk

Peanut allergy rates among children under age 3 have fallen by 43 percent over the past ten years, according to a study released in October 2025. The data suggests that previous medical advice to delay exposure to peanut products may have inadvertently increased the risk of developing the condition.

Medical guidance for infants has shifted in recent years. The American Academy of Pediatrics now recommends introducing peanut products to babies between 4 and 6 months of age. This guidance applies to infants without a prior history of reaction who are already eating other solid foods. Pediatricians advise starting with small amounts and feeding peanut foods at least twice a week through the first year and beyond. Whole peanuts are not recommended for infants due to choking hazards.

Dr. David Hill, the lead author of the new study, attributed the drop in allergy rates to this change in clinical practice. He noted that the reversal in guidance is a major factor in the decline. "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.

For families who have already navigated a diagnosis, the shift in medical knowledge offers a different path forward. Kristie Herring’s son, Parker, suffered from a severe peanut allergy. Herring described the diagnosis as a total surprise given 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.

Experts caution that early introduction is not a guaranteed cure for every child. Food allergy remains a complex condition with multiple causes. Oral immunotherapy carries its own set of risks and requires careful management. Specialists recommend that parents of children with existing peanut allergies consult an allergist to determine the best treatment options.

The study provides data on the effectiveness of the updated guidelines since their implementation. The recommendation to introduce peanut products early stands for all infants meeting the specified criteria. Health providers emphasize the importance of regular feeding schedules to maintain tolerance. Parents are advised to seek professional medical advice for specific health concerns or emergencies.
