Coffee and a Longer Life are Linked

Coffee and a Longer Life are Linked

In fact, drinking lots of coffee was associated with a lower risk of early death, including among people who downed eight or more cups per day.

"For example, prior studies have suggested that variants in CYP1A2, (a gene) encoding the enzyme responsible for more than 95 percent of caffeine metabolism, may alter associations of coffee drinking with cardiovascular-related outcomes, with slower caffeine metabolizers having higher risk of developing hypertension (high blood pressure) or having a myocardial infarction (heart attack) relative to their non-drinking counterparts, whereas faster caffeine metabolizers who drink coffee are at no or lower risk of these outcomes".

The researchers found longevity benefits associated with almost every level and type of coffee consumption.

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.

Coffee contains more than 1,000 biological compounds, including potassium and folic acid, known to have an effect on the body, Loftfield explained.

Drawing information from the UK's Biobank data resource, which holds information on around nine million people, researchers were also able to profile British java drinkers.

"We know that some people metabolize caffeine quite slowly and are less tolerant of the apparent physical affects of caffeine, which of course comes from many sources other than coffee".

"Coffee makes you happy, it gives you something to look forward to in the morning, " said Taylor, a sound engineer from Las Vegas.

One other thing that didn't matter in this study: your DNA. Differences by amount of coffee consumed and genetic variations were minimal. But though it annoys us when it flip-flops, science does advance.

The results do not prove that your coffee pot is a fountain of youth, nor are they a reason for abstainers to start drinking coffee, said Alice Lichtenstein, a nutrition expert at Tufts University in the United States who was not involved in the research.

Drink up, coffee fiends.

And she notes that it's a rare treat when there's something that feels good and actually is good for us.

In addition, the caffeine in coffee may have bad health consequences for some people, she said.

The research didn't include whether participants drank coffee black or with cream and sugar. The study did not distinguish between, say, an espresso and a frappuccino. And the risk of death during the follow-up period was only slightly higher for people drinking around 4 cups of coffee a day compared with those who drank more than 8, he told Live Science.

"These results provide further evidence that coffee drinking can be part of a healthy diet and may provide reassurance to those who drink coffee and enjoy it", the authors wrote in the paper. The researchers observed an inverse association for coffee drinking with mortality, including among participants who reported drinking at least one cup per day, up to eight or more cups per day.
