Drink To Your Health: Study Links Daily Coffee Habit To Longevity

Leave a comment

If you have a daily coffee habit, here’s something to buzz about: A new study finds those cups of joe may help boost longevity.

“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. coffee 1Decaf 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 decreased risk 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. And some of us are even more coffee 10.jpgsensitive. (I feel jittery if I have more than one strong cup!)

One study found that 200 milligrams of caffeine (the equivalent of about two cups of coffee) is an optimal amount to enhance cognitive function and mood among sleep-deprived people. But we don’t all metabolize caffeine the same way.

As we’ve reported, the caffeine amounts in coffee vary wildly. One analysis, conducted by Bruce Goldberger, found a 16-ounce cup of caffeinated coffee from Starbucks could contain anywhere from 250 milligrams to more than 500 milligrams of caffeine.

“Not everyone reacts to coffee in the same way,” says Andrew Maynard, who studies risk assessment at Arizona State University. He summarizes the benefits documented in this study as “small.”
