Earlier studies have suggested beneficial links between coffee drinking and liver disease.
They caution pregnant women and women at high risk of fractures should limit their coffee consumption. And this study is significant because while lower risks of liver disease, cancer, and stroke had been posited in the past, researchers had not been able to pinpoint coffee as the cause.

"The evidence is so robust and consistent across studies and health outcomes, however, that we can be reassured that drinking coffee is generally safe", he continues. "Should doctors recommend drinking coffee to prevent disease?" Evidence in the review came mainly from observational research, so we can't extrapolate our findings to suggest people start drinking coffee or increasing their intake in attempts to become healthier.
"Factors such as age, whether people smoked or not and how much exercise they took could all have had an effect", Professor Paul Roderick, co-author of the study, told BBC.
Finally, Guallar cautions that drinking coffee is sometimes linked with less healthful habits, such as eating sugary cakes or other fatty products.
