About the Project

Applications are invited for a PhD studentship focussed on analysis of cognitive development in children in relation to nutritional status. Lutein and zeaxanthin may be important for cognitive development in children, with some preliminary evidence indicating a positive association between these carotenoids and cognition in childhood. The possible importance of these carotenoids for cognitive development is indicated by the selective accumulation of lutein and zeaxanthin within the developing infant brain. Lutein, in particular, is the predominant carotenoid in the brain tissue from infancy. Despite constituting just 12% of overall infant carotenoid intake, lutein has been shown to account for 59% of total brain carotenoids. This study is designed to explore the specific linkages between the intake of lutein and zeaxanthin, their biological effects and clinical outcomes in children to enlighten any beneficial effects of lutein and zeaxanthin in early life. An intervention study will be conducted to examine the ocular and cognitive impact of carotenoid supplementation in children.
