Drinking coffee may reduce the risk of death, according to two large studies published in the Chronicle of Internal Medicine.

The first study was carried out jointly by researchers from the International Agency for Research on Cancer and Imperial College. Using 16-year follow-up data from more than 520000 people in 10 European countries, they compared death rates between coffee drinkers and non-coffee drinkers. The results showed that there was a link between high coffee consumption and low mortality, with the most significant reduction in mortality among people who drank three or more cups of coffee a day.

In the second study, researchers at the University of Southern California followed the health of 185000 Americans for 16 years, including African-Americans, Japanese-Americans, Hispanics, native Hawaiians and whites. Coffee drinkers had a lower risk of dying from diseases such as heart disease, cancer, stroke, diabetes, respiratory diseases and kidney disease, the study found. This benefit applies to people of different races.

A commentary issued by the Chronicle of Internal Medicine said that the polyphenols and other bioactive substances in coffee have antioxidant effects and are related to reducing insulin resistance and inflammation. However, these benefits do not come from caffeine. Although it is too early to advise people to drink coffee to reduce mortality or prevent chronic diseases, adults drinking 3-5 cups of coffee a day, or 400 milligrams of caffeine a day, may not have adverse effects on their health. as a result, drinking coffee can be considered part of a healthy diet.
