The research, published in the journal the Annals of Internal Medicine, suggests an extra cup of coffee could lengthen a person's lifespan - even if it is decaffeinated.
But sceptical experts point out it is impossible to say for sure that it is the coffee that is having a protective effect, rather than say, a more healthy lifestyle in coffee drinkers.
They say there is no need to reach for that extra cup of coffee just yet.
What does the new study claim?
Researchers from the International Agency for Research on Cancer and Imperial College London say they have found that drinking more coffee is linked to a lower risk of death - particularly for heart diseases and diseases of the gut.
They came to their conclusions after analysing data of healthy people over the age of 35 from 10 EU countries.
They asked them once at the beginning of the study how much coffee they tended to drink and then looked at deaths over an average of 16 years.
