Children & Food Allergies

It appears that the timing and duration of some childhood allergies are changing. A study of children seen in a Duke University clinic found that the median age of first reaction to a peanut allergy dropped from 24 months to 18 months in the past decade. The likely reason, the researchers say: The age at which children first eat peanuts has also dropped. The American Academy of Pediatrics recommends not giving children peanuts before age three, especially if there’s a family history of allergies.

And milk and egg allergies, once thought to disappear by age three or four, are persisting into adolescence and beyond, say researchers from Johns Hopkins Children’s Center. About 30 percent of kids with egg allergies and 20 percent with milk allergies don’t outgrow them until at least age 16.

The bottom line: “The message parents may get from their pediatrician—that their kids will easily outgrow these allergies —is probably wrong,” says Johns Hopkins researcher Robert Wood, M.D., professor of pediatrics. “Odds are, these allergies will be with them through kindergarten or middle school.”
