The association between drinking coffee and mortality was seen among different races and education levels.
A previous study showed that drinking four or more cups of coffee daily causes headaches, stomach upset, restlessness and a racing heartbeat.
Coffee contains many chemicals, including antioxidants and compounds that can prevent mutations. Click to enlarge this image.
Drinking coffee might help you live longer, a new study suggests.
Results show that death rates over a 13-year period among men and women who drank coffee decreased with a greater number of cups per day, up to six. The trend was seen for deaths from any cause, and from specific causes such as heart disease, respiratory disease, stroke and diabetes. This relationship, however, was not seen for those who died of cancer.
"We observed associations between coffee-drinking and a range of different causes of death, and across a number of different groups," said lead author Neal Freedman, of the National Institutes of Health. "The effect was seen in both men and women, those of different body weights, and in both former and never smokers."
The study showed an association, not a direct cause-effect relationship, between coffee and mortality rates.
Still, while high coffee consumption was previously thought to have adverse health effects, this study adds to the growing body of recent findings that show higher coffee consumption is not harmful, and in some cases may have health benefits, said Jeanine Genkinger, an epidemiology professor at the Columbia University School of Public Health in New York City, who was not involved in the research. Genkinger emphasized that the greatest benefits may come from black coffee — cream, sugar and additives may be detrimental to health.
The study will be published Thursday (May 17) in the New England Journal of Medicine.

One reason coffee drinkers, and green tea drinkers, may live longer is that both beverages decrease stroke risk. One cup of coffee seems to protect as well as four cups of green tea.
Green tea and coffee may help lower your risk of having a stroke, especially when both are a regular part of your diet, according to research published in Stroke: Journal of the American Heart Association.They found that the more green tea or coffee people drink, the lower their stroke risks.
People who drank at least one cup of coffee daily had about a 20 percent lower risk of stroke compared to those who rarely drank it.
People who drank two to three cups of green tea daily had a 14 percent lower risk of stroke and those who had at least four cups had a 20 percent lower risk, compared to those who rarely drank it.
People who drank at least one cup of coffee or two cups of green tea daily had a 32 percent lower risk of intracerebral hemorrhage, compared to those who rarely drank either beverage. (Intracerebral hemorrhage happens when a blood vessel bursts and bleeds inside the brain. About 13 percent of strokes are hemorrhagic.)
This makes me happy, since I drink around 62 oz/day of green tea.
