A new study from researchers at University College Cork has explored how both caffeinated and decaffeinated coffee may affect the gut microbiome and the gut-brain connection.
The study, published in Nature Communications, found that coffee consumption was associated with changes in gut bacteria and differences in mood, stress and cognitive measures.
Interestingly, the researchers observed different effects:
Caffeinated coffee was associated with reduced anxiety and improved vigilance and attention.
Decaffeinated coffee was associated with improvements in learning and memory.
Both types were also associated with lower perceived stress, depression and impulsivity scores.
So, is your morning coffee affecting your brain through your gut?
Scientists may be getting closer to understanding the connection.
