Mechanisms and evidence for the role of nutrition in cognitive ageing

Public Forum Papers Invited Paper

Abstract

This review examines the mechanisms and empirical evidence from epidemiological and experimental studies for the role of the B vitamins folate and vitamins B-12 and B-6, antioxidants, omega 3 polyunsaturated fatty acids (PUFAs) and the popular herbal supplement, Ginkgo biloba in the maintenance and enhancement of cognitive performance in older adults. Although there are plausible mechanisms by which these dietary components could affect cognition, these hypothesized effects are yet to be clearly substantiated. As the effects of dietary components on cognitive performance are likely to be subtle, methodological issues such as appropriate outcome measures and adequate sample sizes need careful consideration.
