Worried about peanut allergies in your little one? You’re not alone! Many parents are concerned about food allergies, especially when it comes to peanuts. But here’s some fantastic news: a simple shift in how we introduce these foods is making a real difference, dramatically reducing peanut allergy rates in children.
This is according to the American College of Allergy, Asthma and Immunology (ACAAI), released on November 20, 2025. Recent studies show a remarkable 43% drop in peanut allergy cases among children under 3 years old over the past few years!
This positive trend aligns with the findings of the 2015 Learning Early About Peanut Allergy (LEAP) study and subsequent guidelines from the National Institute of Allergy and Infectious Diseases and the ACAAI in 2017. These guidelines encouraged allergists and pediatricians to advise parents on a new approach: introducing small amounts of peanut products early in infancy. The goal? To help the immune system learn to tolerate peanuts, potentially preventing severe allergic reactions later in life.
But here’s where it gets interesting… A study from the Children’s Hospital of Pennsylvania (CHOP) analyzed health records of over 120,000 children, confirming that early introduction helps the immune system. This study also revealed that the early introduction method corresponded to a 36% reduction in all new food allergy cases, including common culprits like milk, eggs, and tree nuts. This suggests that the guidelines are working in the real world!
As explained by allergist Dr. Cherie Zachary, president of ACAAI, “These study results are very promising.” She further noted that the early introduction approach can also help parents address other potential food allergies, including eggs, which have now become the most common food allergy among children since the decline of peanut allergy.
What about high-risk babies? If your infant has severe eczema or already has an egg allergy, they’re considered high-risk. In these cases, introducing peanut products under an allergist’s supervision is recommended. The guidelines suggest introducing peanut-containing foods as early as 4-6 months for high-risk infants who have already started solid foods, after ensuring it’s safe. It’s crucial to consult an allergy specialist for testing and to introduce the peanut product in their office initially.
And this is the part most people miss… For moderate-risk infants (those with mild to moderate eczema), peanut-containing foods can be introduced at home around six months old. Low-risk infants (no eczema or egg allergy) can also have peanut-containing foods introduced around six months, following family preference, but only when the child is healthy. Avoid introducing peanuts if your child is sick. Remember to introduce age-appropriate peanut-containing foods only after infants have started eating other solid foods first.
Important reminder: Never give whole nuts to infants or toddlers due to the choking hazard.
Dr. Zachary emphasizes that these changes are making a huge difference. “Parents can now feel even more confident that early introduction is an effective way to reduce the risk of developing peanut allergy later in childhood.”
