Peanut allergy rates in young children fall 43 percent in 10 years

The rate of peanut allergies among children under age 3 has dropped by approximately 43 percent over the last ten years. A study released in October 2025 identifies a shift in medical advice as a primary driver of this decline. Doctors now recommend that parents introduce peanut products to infants between 4 and 6 months of age, provided the babies are already eating other solid foods.

Dr. David Hill, the lead author of the study, stated that the new guidance has likely prevented tens of thousands of new food allergy diagnoses. He noted that avoiding peanuts for young children, the standard practice for decades, may have increased the risk rather than lowered it.

Kristie Herring, a mother from the local area, shared her family’s experience with the condition. Her son, Parker, developed a severe peanut allergy that Herring described as a total surprise given their family history. Parker is currently undergoing oral immunotherapy. This treatment involves slowly increasing doses of peanut protein to build tolerance. The process has allowed him to safely eat peanut butter again.

The American Academy of Pediatrics advises that pediatricians start small and feed peanut foods to infants at least twice a week. This recommendation continues through the first year and beyond. Health officials stress that this advice applies to infants without a history of prior reaction. Parents are warned never to give whole peanuts 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. For families whose children have already developed an allergy, specialists recommend consulting an allergist about treatment options. These families are advised to maintain close vigilance in managing the condition.

The study suggests that the previous medical consensus to delay peanut exposure was the wrong approach. By changing the timing of introduction, healthcare providers have altered the trajectory of childhood food allergies. The data shows a clear correlation between early exposure and lower diagnosis rates in the under-3 demographic.

Families are encouraged to speak with their child’s doctor before starting peanut products. The new guidelines apply to all infants meeting the age and developmental criteria. This change in practice aims to reduce the number of children who develop an allergy later in childhood.
