Three or four cups of coffee a day does you more good than harm – our new study suggests : The Conversation


Drinking moderate amounts of coffee – about three or four cups a day – is more likely to benefit our health than harm it, our latest research shows. This is important to know because around the world over two billion cups of coffee are consumed every day.

Earlier studies have suggested beneficial links between coffee drinking and liver disease. Our research group has an interest in liver conditions. As such, we had previously conducted two meta-analyses, one looking for links between coffee drinking and cirrhosis and another at coffee drinking and cancer of the liver. We found that there was a lower risk of both conditions in people who drank more coffee.
