Summary:Background: The recent dietary reference intakes publication provides updated information on the physiologic and dietary requirements for zinc and proposes new tolerable upper intake levels. Objective: We analyzed dietary intake data of US preschool children to determine the prevalence of inadequate and excessive intakes of zinc. Design: Diets of 7474 nonbreastfeeding preschool children in the Continuing Survey of Food Intakes by Individuals (1994-1996 and 1998) were analyzed for the intakes of zinc and other dietary components, and factors associated with zinc intake were examined. Results: The mean intakes of zinc by children aged
