New peanut allergy prevention guidelines start in infancy

Story highlights

  • Some infants should be introduced to peanut-containing foods as early as 4 months
  • Peanut allergy affects about 2% of the children in the United States

(CNN)Peanut allergy affects about 2% of the children in the United States, and those numbers appear to be growing.

A serious peanut allergy can lead to anaphylaxis and, rarely, even death, which means some parents avoided introducing peanuts to their children.
But on Thursday, an expert panel published new guidelines about when to introduce some infants to peanut-containing foods as a way to prevent food allergies, a technique validated by the Learning Early About Peanut allergy, or LEAP, study.
    "Many, many people were asking their doctors, their pediatricians, 'We've heard about this wonderful information; what should we do?' " said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. "The professional societies -- such as the American Academy of Pediatrics, the American Academy of Family Physicians, the American Academy of Allergy, Asthma & Immunology, etc. -- all decided they needed to get together and sit down in a few meetings and put together some guidelines."
