Abstract
A growing number of research studies have examined the potential benefits of cocoa flavanols supplementation on neuro-physiological processes and cognitive enhancement. However, the results have led to limited evidence on both chronic and acute effects. This study investigated whether acute cocoa flavanol consumption might modulate interference and inhibitory control responses. In order to test the effects on cognition, we implemented the Flanker, Go/No-Go and Simon tasks. Thirty-six healthy university students, aged 19-29 years, completed this randomised, gender-balanced, double-blind, placebo-controlled, counterbalanced, crossover study. In three separate days, participants received drinks containing 622.5 mg (medium condition), 415 mg (low condition), and 0 mg (placebo) cocoa flavanols. They completed the experimental tasks one-hour post-ingestion. Compared to the placebo, neither the medium nor the low conditions significantly reduced reaction times and improved accuracy in the three tasks. We conclude that acute cocoa flavanol intake did not modulate interference or inhibitory control functions.
