A recent report suggests that a significant percentage of young children who are allergic to peanuts grow out of the allergy, in contrast to the persistent allergy in older children. Researchers at London’s Institute of Child Health studied 15 young children with resolved peanut allergy and 15 with persistent allergy to collect data and found that 18% of the younger children challenged with peanuts had negative results (no allergic reaction). Authors note that children with no other food allergies at the time of the study had a better chance of negative challenge results. The report is in the British Medical Journal.
