A new study suggests that drinking coffee can enhance the odds for longer life, including those who drink eight cups of coffee a day. More specifically, new research links drinking coffee to longevity after surveying 500,000 British adult coffee drinkers. The study reported that those who regularly drank coffee presented a somewhat reduced risk of premature death.
The seeming longevity improvement is observed with ground coffee, instant coffee, and decaffeinated coffee, as reported by the US researchers who participated in this study. This study is also the first significant study to indicate the coffee consumption is beneficial even for people with genetic abnormalities that affect the normal caffeine metabolism of their bodies.
In general, the scientists proved that coffee drinkers present between 10 and 15 percent lower risk of premature death over about ten years of follow-up, and the variations between the quantity of coffee drunk and the differences in genetics were minor influencers.
Drinking coffee linked to longevity – Here is how can caffeine be beneficial
For the survey, the scientists asked about 9 million UK residents to participate, but only 500,000 million British adults, both men and women, aged between 40 and 69 accepted the survey. The participants filled out quizzes on daily coffee intake, physical activity, and other routines they have, and underwent physical examinations, which included blood tests.
Over the follow-up period, about 14,000 of the subjects died of cancer or cardiovascular diseases.
However, how coffee can positively influence longevity is still a matter of debate among the study’s authors, but, some of them believe that the more than 1,000 compounds in coffee, out of which the majority are antioxidants, help protect the cells in the body and reduce inflammation. On the other hand, the researchers agreed to earlier studies that assessed that caffeine could cause a brief increase in blood pressure but linked that to a genetic mutation that slows down caffeine metabolism.
Also, the researchers indicated that the study’s results are not meant to make people who don’t drink coffee to start drinking coffee, and even they recommended people to drink black coffee, that is, without added milk, cream, or sugar. Find more info here on making your perfect cup of coffee.
