People in Finland are the biggest coffee consumers worldwide — they chug an average of 1,640 cups per year each (and that’s the full-strength stuff). When java was first introduced to Finland in the 18th century, it was only sold in pharmacies and was praised as a great cure for depression. Harvard research now backs up that claim. Their studies suggest sipping two cups of caffeinated coffee daily can cut your risk of blue moods by 34 percent — and enjoying three or more cups daily cuts your risk of depression 42 percent or more. According to the study, coffee’s mix of caffeine and antioxidants stimulates the brain to produce more powerful, natural antidepressant hormones such as serotonin and dopamine.
