Coffee is the second most consumed beverage in the world, after water. So if you are a coffee lover, a new study has good news for you: drinking this liquid is associated with a lower risk of premature death, regardless of the amount you drink and whether or not it is caffeinated.
This is the first major study to indicate a benefit even in people with genetic failures that affect the way their bodies use caffeine.
Coffee: elixir of an almost eternal life
The article, published in the JAMA Internal Medicine, highlighted that after carrying out a study to almost half a million British adults, the drinkers have a lower risk of death, in comparison to those who do not. This apparent increase in longevity was observed with instant coffee, ground or decaffeinated.
Dr. Erikka Loftfield, principal investigator of the study and researcher at the National Cancer Institute, commented on the following:
WE OBSERVED AN INVERSE ASSOCIATION FOR COFFEE CONSUMPTION WITH MORTALITY, EVEN AMONG PARTICIPANTS WHO REPORTED DRINKING AT LEAST ONE CUP PER DAY, UP TO EIGHT OR MORE CUPS PER DAY, AS WELL AS THOSE WHO DRANK FILTERED, INSTANT AND DECAFFEINATED COFFEE.
The researchers used data from the UK Biobank medical agency , through which a group of adults completed health questionnaires, underwent physical examinations and provided biological samples. For the study, the information provided by almost 500 thousand people was analyzed, who answered questions about their coffee consumption, smoking and drinking habits, among others.
The results found longevity benefits associated with almost all levels and types of coffee consumption. In general, the drinkers had between 10% and 15% less probability of dying than the abstainers during the follow-up of a decade, where around 14 thousand people died.
The differences by amount of consumption and genetic variations were minimal, reaching a maximum of 16% for those who drank from six to seven cups a day.
“OUR CURRENT UNDERSTANDING OF COFFEE AND HEALTH IS BASED PRIMARILY ON THE RESULTS OF OBSERVATIONAL STUDIES.” “TO BETTER UNDERSTAND THE POTENTIAL BIOLOGICAL MECHANISMS UNDERLYING THE OBSERVED ASSOCIATIONS OF COFFEE WITH VARIOUS HEALTH OUTCOMES, ADDITIONAL STUDIES ARE NEEDED,” SAID LOFTFIELD.
However, the Loftfield study joins a large group that has found health benefits associated with this liquid. And although some previous studies have linked this liquid and other hot drinks to cancer, the World Health Organization just concluded last month that there is not enough evidence to call coffee a carcinogen.
