So if you drank that coffee, you had a slightly lower chance of dying during the 10 years the study examined.
Of course with so many coffee drinkers across the world, such research tends to make headlines in popular media, which has been aswirl in coffee-and-health-related headlines lately for two reasons: 1) There is in reality more research coming out about the potential health benefits of coffee and its relationship to mortality; and 2) The recent California Proposition 65 ruling caused a significant backlash from the coffee industry and even the public health community, making headlines throughout the nation. That number rises to 16 percent for those who drank six to seven cups, before jumping down to 14 percent for those consuming eight or more.
Previous studies have found coffee drinkers have a 15 percent lower risk of death and are less likely to die from respiratory disease, stroke, injuries and accidents, diabetes, and cardiovascular disease.
It's another piece of good news for coffee lovers, and it gets even better.
I hope you're reading this while drinking a cup of coffee.
With its acquisition of Motivate, Lyft gets in on bike share
The Brooklyn, N.Y. -based company's bike maintenance operations will stay as a standalone business under the current brand. Lyft isn't the only ride sharing company stretching its wings into human-powered transportation.
According to lead author Dr Erikka Loftfield, a cancer epidemiologist at the National Institutes of Health in Maryland, the results held true whether the type of coffee drank was ground, instant or decaffeinated.
That doesn't mean people should dramatically up their coffee intake, though: There isn't enough data to change the guidelines to include more cups of coffee, Loftfield said.
"Participants drinking four or more cups per day, compared with those drinking less coffee and nondrinkers, were more likely to drink instant coffee and be current smokers, whereas participants drinking one to three cups per day were older, more likely to have a university degree, and more likely to report "excellent" health". "But if they don't drink coffee, these findings don't say to start drinking it", Loftfield said. Most were coffee drinkers; 154,000 or nearly one-third drank two to three cups daily and 10,000 drank at least eight cups daily. However, earlier studies focused primarily on health risks after the presence of such diseases were found.
The research, which was published in the JAMA medical journal, states that over the 10-year study, 14,225 participants died.
There are several possible explanations for the health benefits of coffee. The study looked at some common gene variations that help determine whether someone metabolizes caffeine quickly or slowly, but didn't find any difference in health risk.
