It is not the first time that studies have been published linking coffee intake with longevity, but now it seems to have been found an underlying mechanism to this link.
At least that is what researchers from the Institute for Immunity, Transplantation and Infection at Stanford University in California say. The study has been published in the magazine Nature Medicine.
The anti-inflammatory properties of caffeine
Apparently, caffeine (from coffee, tea, chocolate ...) has anti-inflammatory properties, which would increase people's lives, because hay inflammatory process could boost the development of cardiovascular diseases in adult life.
For this conclusion, directed by Mark Davis, leader of the work, the inflammatory processes that could contribute to poor heart health in old age were first identified.
Next, the medical history of each of the major participants in the study was examined. Subsequent research revealed that older participants who had high activity from a group of genes were also significantly more likely to have arterial stiffness, a risk factor for heart attack and stroke. But what they also found is that it was more likely to find caffeine metabolites in the blood of older adults with low activity of these gene groups.
By incubating immune cells with caffeine metabolites and nucleic acid metabolites, they discovered that caffeine metabolites prevented the inflammatory effects of nucleic acid metabolites. As he points out Davis:
That something that many people drink, and really like to drink, could have a direct benefit came as a surprise to us. What we have shown is a correlation between caffeine consumption and longevity. And we have demonstrated more rigorously, in laboratory tests, a very plausible mechanism to explain why this could be so.
Remember that coffee is one of the most consumed beverages in the world and also one of the most exportable merchandise in the world. In Spain alone, 22 million people consume at least one cup of coffee a day. And that all these are the most unusual substances in your coffee cup
