Coffee could boost your chances of a longer life, study finds

The study was led by National Cancer Institute researcher Erikka Loftfield and was published in the Journal of the American Medical Association Internal Medicine.

In a study of 9 million British male and female adults, coffee drinkers had a slightly lower risk of death over 10 years (10 to 15%) than those who didn't drink it regularly.

In the paper, the authors write they observed an inverse association for coffee drinkers with all-cancer and all-cardiovascular disease deaths - people who drank between one and eight cups of coffee per day were less likely to have died from these conditions.

Despite that, she also said the results reinforce previous research and add additional reassurance for coffee drinkers.

But something people may not realize that is also beneficial when it comes to coffee, especially during these sweltering summer months, is that coffee does not dehydrate you. "The tastes may vary depending on how you drink the coffee; the chemical compounds that may be beneficial probably don't change as much, so regardless of how you drink coffee, you're probably going to get most of the benefits". The researchers found that the more cups of coffee people drank, the less likely they were to die during the study period.

"Participants drinking four or more cups per day, compared with those drinking less coffee and nondrinkers, were more likely to drink instant coffee and be current smokers, whereas participants drinking one to three cups per day were older, more likely to have a university degree, and more likely to report "excellent" health".


"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. "But when the data were looked at more carefully, and more factors were controlled for, and more contemporary methods of producing the coffee and consuming the coffee were taken into consideration, it seems not only were those potential negative effects not corroborated, but it turns out that a lot of positive effects of coffee were identified". Differences by amount of coffee consumed and genetic variations were minimal. "Or at least not be bad", Lichtenstein said.

"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".

During the period of the study, over 14,000 participants died. Firstly, the study involved a half a million people from the UK Biobank, a 10-year population-based study that ran from 2006 to 2016.

"I try to have just one cup daily", Taylor said. And when all causes of death were combined, even slow caffeine metabolizers had a longevity boost. It doesn't matter what kind of coffee people drink - that includes decaf and instant coffee.

But coffee drinkers in the study didn't have higher risks than non-drinkers of dying from heart disease and other blood pressure-related causes.
