Peanut Allergies: Prevention by Early Exposure?

It might seem obvious that the best way to avoid a food allergy is to steer clear of the offending item. But a recent study, published in the New England Journal of Medicine, suggests that just the opposite may be true: strict avoidance from a very early age may be the wrong strategy when it comes to kids at high risk of developing an allergy to peanuts [1].

The study found that feeding peanut-rich foods to some high-risk infants actually helps their developing immune systems learn to tolerate peanuts better, apparently helping them avoid this serious allergy later in life. While it’s too soon to recommend stepping up peanut consumption among all babies, the findings provide striking new insights into how food allergies develop and how they might be avoided.
