Large study shows drinking coffee could extend your life

Large study shows drinking coffee could extend your life

A cup of brewed coffee represents a contribution of up to 1.8 grams of fiber of the recommended intake of between 20 to 38 grams.

Nonetheless, the new study's findings are a positive for coffee lovers.

Having a morning cup of java - and another and another - might prolong your life, a new study suggests.

The apparent boost was seen among drinkers of instant, ground and decaffeinated coffee and echoed results seen in US-based research. But this is the first large study to show a benefit regardless of a drinker's caffeine metabolism.

In the 10 years of follow-up, more than 14,000 people died.

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

"But here's a situation where there was always some feeling of, 'Oh, can't be - I enjoy it too much, it can't be good for me.' And now we're finding out that it's good". "It's the non-caffeine components that might be responsible for the association", she said.

Research in JAMA Internal Medicine shows people who drank one cup of coffee a day had an eight percent lower risk of dying early.

Results aside, however, it is still not clear exactly how drinking coffee might affect longevity.

To shed light on these concerns, researchers delved into data from the U.K. Biobank study made up of 500,000 individuals across the U.K. between 2006 and 2010.

Other studies have suggested that substances in coffee may reduce inflammation and improve how the body uses insulin, which can reduce chances for developing diabetes.

Two to five cups, one cup per day, or less than one cup per day reduced early death rates by 12, eight and six percent, respectively. "Otherwise I get a little hyper".

For the study, researchers invited 9 million British adults to take part; 498,134 women and men aged 40 to 69 agreed. The low participation rate means those involved may have been healthier than the general United Kingdom population, the researchers said. Participants answered questions about their coffee-drinking habits, health history, and smoking and drinking tendencies, among other things.

Interestingly, even people who admitted knocking back eight cups or more a day were less likely to die than those who refrained from drinking coffee at all.

"During the next decade, 14,225 participants died, mostly of cancer or heart disease", the AP reported.

Caffeine can cause short-term increases in blood pressure, and some smaller studies have suggested that it might be linked with high blood pressure, especially in people with a genetic variation that causes them to metabolise caffeine slowly. And when all causes of death were combined, even slow caffeine metabolizers had a longevity boost.

"This study provides further evidence that coffee drinking can be part of a healthy diet and offers reassurance to coffee drinkers", wrote the National Cancer Institute (NCI) researchers, who analyzed data from almost 500,000 people through the U.K. Biobank, a large-scale genomic and health database.

He added: "Healthier coffee, free from sugar or syrup, should also be encouraged to optimize any health benefit". But Ms Lichtenstein said loading coffee with extra fat and calories isn't healthy.
