Abstract
 Previous research has suggested that antioxidants serve to maintain cognitive function during normal aging. The present study investigated the relationship between dietary antioxidant vitamin levels and sub-components of working memory in a young and older adult population. Both young (N = 16) and old (N = 19) groups completed three tasks (Tower of London task, mental rotation task and item-order task), each loaded on to a specific sub-component of working memory. Participants also completed a food diary which captured dietary intake over three days. This was analysed for mean daily intake measurements of antioxidant vitamins E and C. Results revealed a significant association between vitamin E levels and Tower of London task performance in older adults. No other meaningful associations between task performance and antioxidant vitamin levels were observed for both young and old groups. These findings suggest that vitamin E may play a role in maintaining the capacity of the Central Executive during normal aging.
