Abstract
The INCAP longitudinal study (1969–1977) was designed to test the hypothesis that nutrition supplementation improves the cognitive test performance of infant and preschool children. The hypothesis was based on a series of arguments about effects of supplementation on brain development that have not been supported by subsequent research. Both early reports of these studies and current re-examination of the data suggest effects during the preschool years, but of modest magnitude.Keywords
