LEAP-ON Study: Early Peanuts Prevent Allergies

A followup study to the LEAP study (The Peanut Story -From NEJM Blog | gutsandgrowth) shows that early peanut exposure produces a durable protection from peanut allergies. NPR summary: Peanut Mush in Infancy Cuts Allergy Risk

Here’s an excerpt:

Researchers followed the kids for one additional year. The kids were between 5 and 6 years old during this follow-up period. It turned out, these high-risk kids’ tolerance to peanuts held up even if they stopped eating peanuts.

“A 12-month period of peanut avoidance was not associated with an increase in the prevalence of peanut allergy,” the authors write in the paper.

This is an important finding, because it wasn’t known whether the kids would need to maintain regular weekly consumption of peanuts in order to stave off developing an allergy…

But that doesn’t mean all parents should just rush in with the peanut mush. The guidance recommends that “infants with eczema or egg allergy in the first 4 to 6 months of life might benefit from evaluation by an allergist” — before they’re introduced to peanut-based foods.
