The purpose of this randomized control trial is to test the impact of provitamin A carotenoid biofortified maize meal consumption on maternal and infant vitamin A status.
Vitamin A deficiency remains a major public health problem in low and middle income countries. Approximately 50% of Zambian children are thought to be affected. This randomized control trial will test the efficacy of provitamin A carotenoid biofortified maize meal consumption as a strategy to improve vitamin A status among lactating Zambian mothers and their infants. The investigators will enroll up to 255 mother/infant pairs to a three-month study, during which they will receive one of the following three interventions: 1) conventional white maize, 2) provitamin A carotenoid biofortified orange maize, or 3) preformed vitamin A fortified white maize.
