Your daily coffee may be doing more than keeping you awake — scientists found a surprising link between your gut, brain and coffee habit

A recent study examined how coffee consumption affects mood and gut health in regular drinkers. Researchers found that both caffeinated and decaffeinated coffee influenced psychological measures and gut bacteria. Although changes were noted, the study did not conclusively prove coffee's benefits for mental health. The influence of gut bacteria on brain signaling after coffee consumption posed new scientific inquiries. Larger and longer studies are necessary to further understand these interactions.
