Coffee drinking may be associated with mortality

American researchers wrote in the latest issue of the New England Journal of Medicine that they used US nutritional intake data to select 400000 middle-aged and elderly people aged 50 to 71 who had reported their food intake every year since 1995. Follow-up survey until 2008.

During the 14-year period, 13% of men and 10% of women in the non-coffee control group died; in the control group who drank more than six cups of coffee a day, 19% of men and 15% of women died.

The "apparent result" seems to be that coffee drinking is associated with high mortality. But the researchers point out that coffee drinkers tend to smoke, drink and eat red meat, and when these lifestyle factors are removed from the results, the effectiveness of coffee is reversed.

Further research found that men who drank more than two cups of coffee a day anyway reduced the risk of death by 10 per cent and women by 16 per cent.

Drinking coffee may reduce the incidence of some diseases or accidents, thereby reducing mortality, Reuters reported on the 17th, citing a paper in the New England Journal of Medicine. Significantly associated with coffee drinking was a decrease in the incidence of heart disease, stroke, infection, injury and accident.

However, the researchers issued this conclusion cautiously, saying that the limitation of the study was a "general survey" and was not an academic study because it was not determined which ingredient in coffee could reduce mortality.

In fact, there are many ways to study coffee and health for many years, but the conclusions are contradictory. Some studies have found that coffee can reduce the risk of diabetes, while others have concluded that coffee increases the incidence of heart disease.
