Coffee drinking — even more than six cups a day over the course of almost 20 years — won’t kill you, and may even help you live longer, says a new study.

While new research suggests coffee can contribute to longevity, researchers urge a spoonful of caution.

Researchers from Harvard and the Universidad Autonoma de Madrid used 20 years of surveys from two groups of health professionals to draw their conclusion: death does not come any sooner for those who drink more coffee.

“I think the main conclusion is that, for those coffee drinkers, they can be quite sure that coffee doesn’t increase their risk of death,” said Esther Lopez-Garcia, the study’s lead author.

So, time to break out the Folgers or head over to Starbucks, right?

Not so fast. People love drinking coffee — the National Coffee Association estimates that the United States imported almost 6 million bags in the last three months of 2006 alone; so, coffee, like red wine or dark chocolate, is a popular choice for these kinds of studies.
