But now there is the possibility that that one day they wont have to worry:
WASHINGTON (AP) — Scientists have the first evidence that life-threatening peanut allergies may be cured one day.
A few children now are allergy-free thanks to a scary treatment — tiny amounts of the very food that endangered them.
But over several years, the children's bodies learned to tolerate peanuts. Immune-system tests show no sign of remaining allergy in five youngsters, and others can withstand amounts that once would have left them wheezing or worse, scientists reported Sunday.
