I recently came across the headline, “Drinking coffee linked to lower suicide risk in adults.” The article detailed a recently published study that examined coffee and caffeine intake of 208,424 people enrolled in three different multi-decade studies. Consumption of caffeine, coffee, and decaffeinated coffee was assessed every 4 years by food-frequency questionnaires.
During the study periods, 277 people died by suicide, according to their death certificates.
The researchers found a correlation between people who drank more coffee (2-4 cups per day), and a 50 percent decrease in their risk of death by suicide.
But, like with most studies of this nature that simply follow a cohort of individuals over time, researchers can’t really tell you which way this correlation goes.
Are people who drink more coffee really at less risk for suicide?
