Having coffee in the morning, during a break in the office or after a meal, is a mandatory drink for many people, who do not usually see it as a gesture to take care of their bodies.
While the health benefits of regular coffee consumption have been debated for a long time, two new and extensive studies confirm the benefits of the drink. The first of these studies was carried out in ten European countries, including France, and the second in the United States.
Since they are only observational studies, they do not prove the link of cause and effect, warn researchers.
The results of the two studies conducted, adjusted for risk factors such as smoking, are published in the American medical journal Annals of Internal Medicine.
Consumers who drink about three cups of coffee per day, including decaffeinated, seem to have a longer life expectancy than those who do not, according to the European study analyzing data for 520,000 men and women.
“We found that increased coffee intake was associated with lower risk of all-cause mortality, especially circulatory disease and the digestive system,” says Marc Gunter of the International Agency for Research on Cancer and One of the main authors of this study.
“These results were similar in the ten European countries with different consumption habits and cultures,” added Gunter.
The second study was conducted in the United States on over 185,000 adults of all origins, aged 45-75 years, over an average of sixteen years. The authors found a link between increased coffee consumption and a lower risk of mortality from cardiovascular, respiratory, renal, cancer and diabetes. More specifically, people who drank a cup of coffee per day had 12% less risk of dying during the study period than those who did not drink, a level that reached 18% for those consuming three cups.
As in the European study, the effects were similar with decaffeinated coffee. “You can not tell the public to drink coffee to prolong your life, but you can see it as a link,” says Veronica Setiawan, a professor of preventive medicine at the University of Southern California and principal author of the work.
