Study says 1 in 13 US children have food allergy

CHICAGO — Food aller­gies affect about one in 13 U.S. chil­dren, dou­ble the lat­est gov­ern­ment esti­mate, a new study sug­gests. The researchers say about 40 per­cent of them have severe reac­tions — a find­ing they hope will erase mis­con­cep­tions that food aller­gies are just like hay fever and other sea­sonal aller­gies that are trou­ble­some but not dangerous.
