Randomised, Double-blind, Placebo Controlled, Parallel Trial Investigating the Daily Effects of Blueberry (Poly)Phenol Consumption on Vascular Function and Cognitive Performance in Healthy Elderly Individuals

Foods rich in certain (poly)phenols, particularly flavonoids, such as berries and cocoa, have been shown to improve measures of vascular function as well as cognitive performance in human intervention studies. This is a randomized, double-blind, placebo controlled, parallel trial investigating the effects of daily blueberry (poly)phenol consumption on vascular function and cognitive performance in healthy elderly individuals. The study will be conducted at King's College London, Franklin-Wilkins Building. Eligible subjects will be healthy males and females aged 65-80.
