Come on, take this cup of coffee. Even several others. A new study shows that this could increase the chances of a longer life, even for those who drink up to eight cups a day.
According to the study that included nearly half a million British adults, coffee drinkers have a lower risk of death in 10 years than those who do not. have not.
This apparent increase in longevity was observed with instant coffee, ground or decaffeinated, a result similar to that of an American survey. This is the first major study to indicate a benefit even in people with genetic deficiencies that affect the way their body uses caffeine.
In general, coffee drinkers were between 10% and 15% less likely to die than abstainers during a decade of follow-up. Differences in the amount of coffee consumed and genetic variation were minimal.
The results do not prove that your coffee maker is a source of eternal youth or that everyone starts drinking coffee, says Alice Lichtenstein, a nutrition expert at Tufts University who was not part of the research . But he added that the results reinforce previous studies and provide additional confidence to coffee drinkers.
"It's not hard to believe that something we love so much, can be good for us – or at least not bad," said Lichtenstein.
The study was published Monday in the journal JAMA Internal Medicine.
It is not clear how drinking coffee affects longevity. Lead author Erikka Loftfield, a researcher at the US National Cancer Institute, said that coffee contains over 1,000 chemical compounds, including antioxidants that help protect cells.
Other studies indicate that the substances contained in coffee could reduce inflammation and improve the way the body uses insulin, which can reduce the risk of developing diabetes. The task of explaining a potential longevity benefit continues, Loftfield said.
For the study, the researchers invited 9 million Britons to participate; 498 134 women and men between 40 and 69 years did it.
Participants completed questionnaires on daily coffee consumption, exercise and other habits, and received physical exams, including blood tests. Most of them drank coffee: 154,000 took two or three cups a day and 10,000 drank at least eight cups a day.
Over the next decade, 14,225 participants have died, mostly from cancer or heart disease.
As in previous studies, those who drink coffee are more likely to drink alcohol and smoke, but the researchers took these factors into account and it seems that drinking coffee has thwarted.
