Zinc-Fortified Foods Do Not Improve Intake of Total Dietary Zinc for Ontario Preschoolers

Overall, zinc-fortified foods and supplements contributed minimally to the total dietary zinc intake amongst these preschoolers. These children did not have inadequate intakes of zinc and intakes in excess of the TUL were only evident in the youngest age group. Food fortification and parental choice to use a multivitamin-mineral supplement did not appear to play a role in either preventing inadequate or causing excessive zinc intake.
