People who drink coffee every day live longer than those who drink less or no coffee.

A study of 400000 people by the National Institutes of Health found that people who drank coffee every day lived longer than those who drank less or less.

Coffee drinkers have a lower risk of dying from heart attacks, strokes, infections and other diseases, the researchers said, but they also suggested that the findings should be interpreted with caution because they only measure the subjects' coffee drinking habits over a certain period of time. and it is not clear what substances in coffee are good for your health.

"Coffee has an effect on the brain, which may be one of the factors that reduce the risk of death, and it may also have an impact on people's bone health," the researchers said. " They found that men who drank more than two to six cups of coffee a day had a 10% lower risk of death than non-coffee drinkers, compared with 16% for women.

There have been different opinions on whether coffee has an effect on human health. Studies have shown that coffee drinkers have a lower risk of developing diabetes, but other studies have shown that coffee may increase the risk of heart disease.

Researchers say people don't have to change their coffee drinking habits until new research on coffee is available.
