Decaffeinated Coffee Linked to Stress Reduction and Improved Memory, Study Finds
A new study published in Nature Communications by researchers from APC Microbiome Ireland at University College Cork reveals significant insights into how coffee affects the gut-brain axis. The research indicates that both caffeinated and decaffeinated coffee influence the gut microbiome, mood, and cognitive functions, though through different mechanisms. In a trial involving 62 participants, those who consumed coffee showed altered gut bacteria profiles, including increased levels of Eggertella sp and Cryptobacterium curtum, which support digestive health. Notably, decaffeinated coffee was associated with clear improvements in learning and memory, likely due polyphenols rather than caffeine. Conversely, caffeinated coffee reduced anxiety and enhanced alertness. Both groups reported lower stress and depression levels, suggesting that coffee's mood-enhancing benefits are not solely dependent on caffeine. The study highlights the complex relationship between digestive and mental health, emphasizing that moderate coffee consumption can positively impact psychological parameters and intestinal metabolites. These findings contribute to a deeper understanding of the biological mechanisms linking diet, gut health, and brain function.
