Effects of blackcurrant juice on pre-frontal cortical haemodynamics and cognition in healthy young adults
Study Details
This new study recruited 20 healthy young adults to consume either…
1️⃣ Blackcurrant juice (500mg polyphenols)
2️⃣ Control (polyphenol-free blackcurrant juice)
60-mins after consumption participants were assessed on…
🎯 Attention
⚡️ Working memory
🩸 Prefrontal cortical haemodynamics
…at rest and during cognitive load 💭
Here is what they found ⬇️
Key Findings
Blackcurrant juice resulted in significant acute modulations of pre-frontal cortex haemodynamics 🩸
…at both rest and during the cognitive task.
This was indicated by…
📉 a decrease in deoxygenated haemoglobin
📈 an increase in left hemisphere oxygenated haemoglobin during task performance
However, no effects on cognitive performance were found ❌
Conclusion
Polyphenol-rich blackcurrant juice can enhance cerebral blood flow ✅
Although this study did not find any significant effect on cognitive performance, further studies are warranted 🔍
