Early Peanut Introduction Helps Kids Avoid Allergies, Study Finds

Huge news for families across California and beyond! Major outlets from the New York Times to ABC News are reporting a major win in children’s health. A new study led by Dr. David Hill at the Children’s Hospital of Philadelphia shows peanut allergies in children have plummeted. Thanks to the “early and often” approach to introducing peanuts, about 60,000 kids have avoided developing peanut allergies.

It all began with the groundbreaking LEAP study, short for Learning Early About Peanut Allergy. That research showed that giving babies small amounts of peanut products early in life could dramatically reduce the risk of allergy. The findings led to national guidelines in 2015 and 2017, encouraging early introduction for most infants.

Now, this doesn’t mean every baby should start with peanuts right away. Always check with your pediatrician for guidance. But one thing’s certain—early introduction is reshaping how we think about preventing food allergies.
