The Story: So many of us splash coffee, worldwide, that any advantage or risk from it would make a large disproportion to open health. So there have been a ton of studies comparing coffee drinkers to those weirdos who don’t hold a stuff. The formula are mixed, though many of a new studies contend coffee drinkers live longer. (2012, yes; 2013, no; 2015, yes.)

So, what’s in this year’s crop? Two large studies: one involving 521,330 people in 10 European countries; and another of 185,855 people in Hawaii and Los Angeles, mostly people of color. (Previous coffee studies were overwhelmingly white, so this is a good further to a science.)

Yes, coffee drinkers lived longer. Yes, even if they were celebration decaf. But all of these coffee studies are observational. They didn’t incidentally allot people to splash coffee or not; people chose themselves. Coffee drinkers in both studies were reduction expected to smoke, for example, and a researchers practiced their numbers to comment for that. But there could have been a ton of other risk factors they didn’t know to adjust.

The Takeaway: Coffee competence be good for you, though afterwards again, being a kind of chairman who drinks coffee competence only be a vigilance that you’re already healthier.
