If your child outgrows a peanut allergy, he or she should have foods containing peanuts at least once a month to prevent the allergy from returning, a new study suggests.According to the results of the research, eating something with peanuts at least that often will help maintain a tolerance to them. But even though the allergy has apparently disappeared if the amount of peanuts eaten is limited, children should carry epinephrine for a while just in case a reaction develops.
