It contains a number of wonder compounds which possess antioxidant, anti-inflammatory, anticarcinogenic properties which scientists believe might explain why drinkers experience lower rates of chronic liver disease and liver cancer.
There was less evidence for the effects of drinking decaffeinated coffee, but it had similar benefits, they said.
Dr Poole and researchers from the University of Edinburgh reviewed 201 studies that had aggregated data from observational research and 17 studies that collected statistics from clinical trials.
The BMJ said that to three to four cups of coffee a day is categorised as a moderate intake - 400mg or less per day.

"That said, our results suggest moderate coffee drinking - up to around three cups per day - is not detrimental to your health, and that incorporating coffee into your diet could have health benefits".
Further research may now be needed to determine whether the relationship highlighted by this study is a causal one.
Experts said it is the largest ever study looking at coffee consumption and health.
While its consumption is still linked to harm in pregnancy, it has shown "beneficial associations" with rates of Parkinson's disease and depression.
