Nov. 14, 2016 — Parents are learning that the old advice to wait to give babies peanuts until they’re at least a year old was wrong.
A highly regarded study published last year found that early exposure can slash a child’s chances for developing peanut allergies by about 80%, a truly life-changing gift.
But how do you work peanuts into a baby’s diet, especially since the whole nuts themselves are a choking hazard? How much and how often do babies need to eat to see a benefit? And what if your baby is considered at high risk of having a peanut allergy?
Allergists and pediatricians have been mulling those questions for more than a year, and they gave us a sneak peek at those new recommendations at the American College of Allergy, Asthma, and Immunology Annual Meeting in San Francisco last week.
The official guidelines from the National Institutes of Health will be released early next year.
The first thing to consider is your child’s chance of having an allergy. Early exposure is particularly beneficial for a group of children who are vulnerable to developing a peanut allergy because they’ve got other risk factors — like a moderate to severe case of the skin condition eczema, an allergy to eggs, or both.
(Lots of babies get a little eczema from time to time. That doesn’t necessary mean they have a higher chance of having a peanut allergy. Doctors are most worried about kids who need longer or more frequent treatment with steroid creams to clear their skin, or kids that have eczema on a large portion of their bodies.)
If they don’t have either of those risk factors, you should still feed them peanuts, but you can be fairly casual about it. You don’t need to worry so much about how much or how often. Just start offering them some peanut-containing foods sometime before their first birthday — that’s supposed to be the optimal window for training the immune system.
“There’s a magic window where we can take advantage of the developing immune system where we can promote tolerance by introducing it,” says David Stukus, MD, a pediatric allergist at Nationwide Children’s Hospital in Columbus, OH, and one of the authors of the new guidelines.
