Your morning cup of coffee may start to taste even better after a major government study found that frequent coffee drinkers have a lower risk of dying from a variety of diseases, compared with people who drink little or no coffee.

Previous   studies have offered conflicting results on the   benefits, or harm associated with regular coffee consumption.

They were followed until 2008, by which point 52,000 had died. As expected, the researchers found that the regular coffee drinkers in the group were also more likely to be smokers. They are more red meat and fewer fruits and vegetables, exercised less and drank more alcohol -- all behaviors associated with poor health. But once the researchers were able to separate the risks, the data showed that the more coffee a person consumed, the less likely he or she was to die from a number of health problems, including diabetes, heart disease, respiratory disease, infections and even injuries and accidents.
