Cognitive and mood improvements following acute supplementation with purple grape juice in healthy young adults

It would take a lot to extrapolate this to most stroke survivors, they aren't healthy or young. But the real question to be answered; is red wine even better than grape juice for cognition and mood improvements? Both are sorely needed for stroke survivors, When will followup and an updated diet protocol occur?

In this study, researchers explore the benefit of acute supplementation of purple grape juice in healthy young adults. These outcomes in a small sample of healthy young adults propose that purple grape juice can acutely improve aspects of cognition and mood. No major impacts of juice were seen on memory measures, proposing that these may be less susceptible to manipulation following acute supplementation in healthy young adults. Potential mechanisms underlying these impacts include modulation of cerebral blood flow, glucoregulation and inhibition of monoamine oxidase activity, all of which require further exploration.

Methods

• For this research, they designed a randomised, placebo–controlled, double–blind, counterbalanced–crossover study.
• This study evaluated the impacts of 230 ml purple grape juice or sugar–matched control in 20 healthy young adults.
• Computerised measures of episodic memory, working memory, attention and mood were finished at baseline and following a 20–min absorption period.

Results

• In this study, they observed that the purple grape juice significantly enhanced reaction time on a composite attention measure (p = 0.047) and increased calm ratings (p = 0.046) when compared to placebo.
• Order impacts likewise showed an enduring positive effect on pre–dose memory reaction time (p = 0.018) and post–dose calm ratings (p = 0.019) when purple grape was consumed first.
