"In our study, we found people who drank three to five cups of coffee per day had about a 15 percent lower [risk of premature] mortality compared to people who didn't drink coffee," says one of the study authors, nutrition researcher Walter Willett of the Harvard School of Public Health. Decaf drinkers also saw benefits.
The findings, published in the journal Circulation, build on a body of evidence linking a coffee habit to potential health benefits.
As we've reported, previous research has pointed to a of stroke. And, there's some evidence that a coffee habit cuts the risk of Type 2 diabetes, too.
Now, of course, it's possible to overdo it with caffeine. Research has shown that consuming more than 400 milligrams of caffeine can interfere with sleep and create feelings of unease.
We're not sure exactly how coffee is [linked] to all these benefits. The coffee bean itself is loaded with many different nutrients and phytochemicals. And my guess is that they're working together to have some of these benefits.
We [see] similar benefits from caffeinated and decaffeinated coffee. That's important, because it suggests that caffeine is not responsible for [the benefit].
