Dr Oyinlola Oyebode, Associate Professor at the University of Warwick, said: "The main conclusions are moderate coffee consumption is not just safe, but more likely to be associated with benefits to health in the majority of adults".
DRINKING three daily cups of coffee is good for your health, a definitive study claims.
The study authors, led by the university's specialist registrar in public health Dr Robin Poole, said this shows coffee drinking "seems safe within usual patterns of consumption, except during pregnancy and in women at increased risk of fracture". Coffee drinking is also associated with a lower risk of few cancers, diabetes, liver disease and dementia.
The BMJ said that to three to four cups of coffee a day is categorised as a moderate intake - 400mg or less per day.
The greatest benefit was seen for liver conditions, such as cirrhosis of the liver.
To better understand the effects of the most commonly consumed beverage on health, the research reviewed aggregated data from 201 studies that also included clinical trials across all countries.

Experts said it is impossible to know whether the health lift it due to the coffee or other habits that are more common amongst drinkers.
The research that was collected with the proofs from the previous two hundred or more conducted researches indicates that coffee consumption lowers premature death risks and prevents heart diseases. Drinking above that number in the same period didn't appear to show any harm, although the benefits were less apparent.
"Importantly, outside of pregnancy, existing evidence suggests that coffee could be tested as an intervention without significant risk of causing harm", he added. Women seem to benefit more than men with higher levels of consumption if factors like mortality from cardiovascular and coronary heart diseases are considered. They warned people should not start drinking coffee, or increasing their intake, for health reasons.
Dr Marc Gunter, of the International Agency for Research on Cancer, said: "We are not at the stage of recommending people to drink more or less coffee".
