Coffee May Boost Chances For A Longer Life, Study Shows

Coffee May Boost Chances For A Longer Life, Study Shows

Dr. Erikka Loftfield, of the Division of Cancer Epidemiology and Genetics at the National Cancer Institute and author of the study published in JAMA Internal Medicine, told Newsweek: "How well caffeine is metabolized varies considerably from person to person".

The study of almost half-a-million British adults, published yesterday in the JAMA Internal Medicine journal, showed that coffee drinkers had a slightly lower risk of death over 10 years than abstainers.

As with any observational study like this though, where people are quizzed on their past and existing habits, we can't definitively say that coffee causes a longer life.

Because these health benefits were found both in people who metabolize coffee differently and those who drank decaf brew, researchers think something other than caffeine may be at play. About one-third of those surveyed said they drank between two and three cups of coffee each day, and 10,000 of them drank eight or more cups each day.

Additionally, "coffee drinkers were more likely than abstainers to drink alcohol and smoke, but the researchers took those factors into account, and coffee drinking seemed to cancel them out".

Other research has indicated that coffee drinkers are less likely to develop various forms of cancer, Type 2 diabetes, depression, Alzheimer's, dementia, liver cirrhosis, and heart disease. Using non-coffee drinkers as the reference group, the scientists were able to surmise that drinking instant, ground, and decaffeinated coffee was "inversely associated with mortality".

The study included 498,134 non-pregnant participants who drank 1 to up to 8 cups of coffee daily.

"There are many potential beneficial compounds in coffee - there are literally hundreds and thousands of compounds in coffee", he said.




Go ahead and have that cup of coffee, maybe even several more.

However, despite the findings, the researchers are warning people not to significantly increase their coffee intake in a freakish quest for eternal life.

We've guzzled down similar findings before: Just last summer, two separate studies delivered similar good news about coffee and mortality.

It is not clear exactly how drinking coffee might affect longevity. And it also doesn't matter what version of the "coffee gene" people have. The findings were true among all coffee drinkers, even those who might be more sensitive to the effects of caffeine.

And the researchers say there's no added benefit to drinking more coffee than one usually does.

Some people have a gene that metabolises caffeine particularly fast - about four times faster than those with the slow variant of the gene.

That means, for example, if you're adding 500 calories of cream and sugar to a coffee beverage the size of a Big Gulp, you might want to keep an eye on that.
