Caffeinated and decaffeinated coffee lower stress, depression and impulsivity

# Summary Research from UCC's APC Microbiome Ireland found that both caffeinated and decaffeinated coffee reduce stress, depression, and impulsivity by influencing the gut microbiome and the gut-brain axis. The study of 62 coffee drinkers and non-drinkers revealed that while both coffee types provided mental health benefits, decaffeinated coffee improved learning and memory, whereas caffeinated coffee reduced anxiety and inflammation. The findings suggest coffee is a complex dietary factor with distinct health benefits independent of its caffeine content.
