Coffee would have a protective effect against cardiovascular, respiratory and kidney diseases, cancers and diabetes and would increase life expectancy, according to results of two studies published in the medical journal Annals of Internal Medicine.
Three cups of coffee for a better life expectancy
The first study conducted in 10 European countries analyzed the medical data of 520,000 men and women over the age of 35, followed by the European Cancer and Nutrition Survey (EPIC) for 16 years. She highlighted the fact that drinking three cups of coffee a day, even decaffeinated, allows a longer life expectancy. This process would be possible because coffee is particularly rich in antioxidants which play an important role in preventing Cancer.
“We found that greater consumption of Coffee was linked to a lower risk of all-cause mortality, particularly circulatory and digestive system diseases,” says Marc Gunter of the International Agency for Research on Cancer and one of the study’s lead authors. These results were similar in the ten European countries with different consumption habits and cultures”.
The study also showed through an analysis of metabolic biomarkers of a group of 14,000 participants that coffee drinkers would have a healthier liver.
“The results of the European study come to reinforce the growing number of indications suggesting that coffee is not only without risk but can have protective effects”, concludes Professor Elio Riboli, head of the faculty of public health of the ‘Imperial College in London which participated in this work.
Coffee against cardiovascular disease
The second study was carried out in the United States with more than 185,000 adults of all origins, aged 45 to 75, for sixteen years. Researchers have observed a link between higher coffee consumption and a lower risk of death from cardiovascular illnesses, respiratory, renal, cancer and diabetes.
In detail, the analysis revealed that people who drank a cup of coffee a day had a 12% lower risk of dying over the duration of the study than those who did not, a protective effect that increased up to to 18% for those consuming three cups.
The researchers insist on the fact that these two studies remain observational, they do not provide a scientific answer on the link of cause and effect.
