# A third of babies with peanut allergy outgrow it by age 1, study finds

New Scientist reports that roughly one in three infants diagnosed with peanut allergy no longer react by their first birthday. The finding suggests early diagnosis in babies does not always mean lifelong allergy, which matters for parents and doctors deciding on testing and treatment. It may also inform guidance on when to reintroduce peanuts under medical supervision.
