Still, it’s not definitive. Rather, it’s part of a growing body of evidence that, at the moment, can say little about how much coffee people should drink. “It may be good for you,” says Dariush Mozaffarian, dean of the Friedman School of Nutrition Science and Policy at Tufts University. “I think we can say with good certainty it’s not bad for you.” (Additives are another story.) Getting more specific will require more research. Last year, Mozaffarian and others called on the National Institutes of Health to establish an institute for nutrition science that could coordinate those efforts and, crucially, help people interpret the results. “We need a well-funded, well-organized, coordinated effort to figure out nutrition,” he says. “No single study gets to the truth.”

The short answer is YES!, more people should drink coffee, it’s delicious.
