Large study shows drinking coffee could extend your life

Large study shows drinking coffee could extend your life

The study was published Monday in the journal JAMA Internal Medicine.

Generally speaking, people who drank two to three cups of coffee every day had a lower risk of death than those who didn't.

For the study, researchers 10 years ago invited nine million British adults to take part; 498,134 women and men aged 40 to 69 agreed.

A study published past year in The BMJ British medical journal looked at more than 200 previous studies and suggested drinking three to four cups of coffee a day can positively impact health more than cause harm.

I hope you're reading this while drinking a cup of coffee.

That may surprise you if instant coffee tastes terrible to you and some brewed coffee tastes heavenly.

Edward Giovannucci, a professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health, who was not part of the study, agreed.

Christopher Gardner from the Stanford Prevention Research Center explains to NPR that coffee has some polyphenol-like, antioxidant-rich compounds. And don't forget that energy drinks, chocolate and tea are all sources of caffeine, too. "It didn't drill down that much", said Eisenberg.

However, some health officials say more research should be done before you change your coffee routine.

One other thing that didn't matter in this study: your DNA.

This study also looked at another question scientists have been asking: how genetics affects coffee consumption. They too showed a beneficial effect when they drank coffee regularly. But though it annoys us when it flip-flops, science does advance. "Or at least not be bad", she said. Some people are more sensitive to the effects of coffee.

Wellington barista Clarke Gardiner is welcoming evidence from a major United Kingdom study linking coffee consumption with a lower risk of premature death.

But, she added, for non-coffee drinkers, the modest benefits aren't a reason to start. The study did not distinguish between, say, an espresso and a frappuccino.

The volunteers were mostly British and have different coffee-drinking habits than much of the rest of the world.

Previous studies have found coffee drinkers have a 15 percent lower risk of death and are less likely to die from respiratory disease, stroke, injuries and accidents, diabetes, and cardiovascular disease.

A new study suggests that drinking coffee may boost your chances for a longer life. The researchers tried to see if moderate amounts of coffee consumption per day was good for health and if heavy intake of coffee (more than 5 cups per day) cause raised risk of death among those who are more sensitive to coffee (poor coffee metabolizers). Coffee habits, complete smoking data and mortality rates for the study participants were taken over that 10 year period.
