There is a lot of opinion about coffee but real research is coming in so what does it say.
The pooled results of the meta-analysis indicated that coffee consumers were less likely to develop cirrhosis compared with those who do not consume coffee. For low or moderate coffee consumption versus no consumption hepatic cirrhosis was reduced. Additionally high coffee consumption could also significantly reduce the risk for hepatic cirrhosis when compared with no coffee consumption. The effect of coffee consumption on hepatic fibrosis was summarized as well. Hepatic fibrosis for coffee consumption versus no consumption was significantly protective. The protective effect of coffee on hepatic fibrosis and cirrhosis was also identified in subgroups of patients with alcoholic liver disease and chronic hepatitis C virus (HCV) infection.
Coffee consumption can significantly reduce the risk for hepatic fibrosis and cirrhosis. Here is a link to the study.
There is also research which shows that how coffee is brewed. It is important to use a paper filter to eliminate some harmful substances. This link is to that research for those who want the detail.
