Crusty in the right places. Worth the chew.
Summary
Researchers at APC Microbiome Ireland, University College Cork, published a study in Nature Communications examining how coffee interacts with the gut-brain axis. The study found that both caffeinated and decaffeinated coffee can shape the gut microbiome and influence mood and stress. Decaf was linked to improved learning and memory, while caffeine boosted focus and reduced anxiety. The research suggests coffee works through multiple pathways beyond just caffeine.
