Early Exposure Reduces Peanut Allergy

NBC Nightly News - March 4, 2016 婴儿期接触花生有可能防止危及生命的过敏反应。 Introducing infants to peanuts may protect against life-threatening allergies.


Lester Holt, Anchor, NBC Nightly News: We're back with encouraging medical news in the battle against a growing problem in the U.S.: Dangerous peanut allergies in children. New research out today could give new hope to parents of high-risk kids. It found that exposing children early - very early - may help them avoid peanut allergies altogether. NBC's Erica Hill has details...(BS: There you go!)
Erica Hill, Reporter, NBC News: 3-year-old Cole Schroer was born with a high risk for peanut allergy, but instead of keeping peanuts out of his diet...(BS: You like those things!)...Cole's father, an allergist, introduced them when he was just six months old.
Brian Schroer: There was no scientific evidence one way or the other about how to introduce peanuts to him, so I just decided, we may as well just give it to him.
EH: It's the same approach they took with older son Calvin, now 6 [years old]. For years, the conventional wisdom was that high-risk children should avoid peanuts, the most prevalent food allergen, before the age of 2...(BS: How about one more?)...Now, research is finding what the Schroer family learned early on:
Dr. Clifford Bassett, Allergist, NYU Langone Medical Center: There's an 80% reduction in peanut allergy in individual infants and babies that were exposed to peanut early on in life. So, that's very revolutionary.
EH: Two new studies published in The New England Journal of Medicine (NEJM) further support the thinking. The first found most high-risk children who regularly consumed peanuts from the age of four months until age 5 [years], remained allergy-free even after avoiding peanuts for another year. In a second study, researchers found exposure to other foods at a young age, including eggs, yogurt, sesame and whitefish, could also protect against allergies.
CB: It's very exciting to think that we can have an approach on preventing allergies, particularly food allergies. We're not there yet.
EH: Experts recommend consulting with your physician before introducing potential allergens at home. The Schroer family is confident early exposure worked for their boys. Neither has developed a peanut allergy.
BS: As a father, it really made me feel better that I ended up probably doing the right thing in terms of giving Cole and Calvin peanuts early.
EH: Peace of mind for parent and child. Erica Hill, NBC News, New York.
