Provitamin A Carotenoid–Biofortified Maize Consumption Increases Pupillary Responsiveness among Zambian Children in a Randomized Controlled Trial

An impaired ability to respond to dark conditions suggests Vitamin A deficiency. This article outlines result of a study conducted in Zambia, in which researchers tested consumption of biofortified orange maize alongside white maize, then tested for symptoms of night-blindness or impaired vision. The study suggests that biofortification may be an effective way to prevent these deficiencies.
