A second big study affirms new thinking: Exposing high-risk kids to peanuts beginning in infancy greatly reduces the chance of developing a peanut allergy. And this peanut tolerance holds up as kids get older.
In a landmark new study, researchers found that babies who consumed the equivalent of about 4 heaping teaspoons of peanut butter each week, starting when they were between 4 and 11 months old, were about 80 percent less likely to develop a peanut allergy by age 5. To avoid a choking hazard, doctors say kids should be fed peanuts mixed in other foods, not peanuts or globs of peanut butter.
