Many people who drink tremendous amounts of coffee also smoke heavily, and some of them, the men especially, kinda-sorta tend to die a little early, statistically speaking. Maybe they die from the coffee. Maybe they die from the smoking. Maybe they die from something other than the coffee or the smoking. Maybe they die from car crashes or fight wounds or suicide or malaria or the plague. (The study speaks of death only as “all-cause mortality”).
That seems to be what the data say in this newly published study.
Many news reports seem to simplify what the study says. Those news reports seem to imply that the study says: drinking coffee will kill you.
The study is:
