Whether you are having it double-double, espresso, iced or decaf, a massive study out of Harvard University has found coffee drinkers are more likely to live longer.

Some people say they can’t function without coffee in the morning. It’s that jolt of energy that helps to get you moving.

And now, Harvard researchers have found that drinking two to three cups of coffee a day cuts the overall risk of death by 10 per cent, especially from heart disease, respiratory problems, stroke, diabetes and infections.

The helpful antioxidants in coffee get most of the credit, along with around 1,000 other compounds besides the caffeine.

The study involved more than 400,000 people monitored over a 13-year period.

The entire study can be found in the New England Journal of Medicine.
