An authoritative answer to the coffee/health question

A question may be difficult (or impossible) to really answer, but that difficulty does not prevent authoritative people from supplying authoritative answers.

A November 16, 2015 press release brews up a new authoritative answer to the question “Is drinking coffee good or bad for your health”:

Moderate coffee drinking may lower risk of premature death

Boston, MA – People who drink about three to five cups of coffee a day may be less likely to die prematurely from some illnesses than those who don’t drink or drink less coffee, according to a new study by Harvard T.H. Chan School of Public Health researchers and colleagues….

“Bioactive compounds in coffee reduce insulin resistance and systematic inflammation,” said first author Ming Ding, a doctoral student in the Department of Nutrition. “That could explain some of our findings. However, more studies are needed to investigate the biological mechanisms producing these effects.”

The study is: “Association of Coffee Consumption with Total and Cause-specific Mortality in Three Large Prospective Cohorts,” Ming Ding, Ambika Satija, Shilpa N. Bhupathiraju, Yang Hu, Qi Sun, Walter Willett, Rob M. van Dam, Frank B. Hu [pictured here], Circulation, online November 16, 2015.

The authors and their institution made a video to inform the public that the coffee question has now been answered:
