Coffee drinkers had a reduced risk of death from heart disease, chronic respiratory disease, influenza, pneumonia, and suicide, but not cancer.

The researchers used data from a previous study that included 90,317 adults without cancer or history of heart disease. The participants were followed from 1998 through 2009. At the beginning of the study, they had reported their coffee intake, along with other dietary and health details.
About 8,700 people had died by 2009, accounting to factors like smoking. The researchers found that people who regularly consumed coffee were less likely to have died during the study than those who did not drink coffee.
The risk of death was lowest for those who drank up to four or five cups of coffee per day. According to the results published in the American Journal of Epidemiology, a similar association was seen among people who drank decaffeinated coffee as well.
The researchers found that coffee drinkers had a reduced risk of death from heart disease, chronic respiratory disease, influenza, pneumonia, and suicide, but not cancer.
"Although coffee drinking has also been inversely associated with the incidence of certain cancers, like liver, in epidemiological studies, we did not observe an association between coffee and overall cancer mortality. This may be because coffee reduces mortality risk for some cancers but not others," said Loftfield.
Drinking up to five cups per day, or 400 milligrams of caffeine per day, is not associated with any long-term health risks, Loftfield added.
