Coffee drinkers, new research reinforces previous findings that your daily cup of joe may help you live longer 

Compared to non-coffee drinkers, regular consumers of unsweetened coffee were 16% to 21% less likely to die during a seven-year follow-up period 

Those who added sugar and drank 1½-3½ cups daily of sweetened coffee were 29% to 31% less likely to die, researchers said 

Sweetened coffee drinkers among the 171,616 United Kingdom participants in the study added only one teaspoon of sugar

Drinkers of unsweetened coffee did not rely on any specific amount of coffee daily and consumed ground 

None in the study had any known underlying heart disease or cancer at the outset of the study 

These results bolster previous findings that moderate coffee consumption can be good for your health 

But other research has found that too much coffee – four or more cups daily – can increase health risks
