drinking coffee can help prevent liver cancer...

In the last decade studies have consistently suggested that coffee drinking may be protective against the development of hepatocellular (liver) cancer, though currently the exact mechanism of action has yet to be identified. (Taylor-Robinson 2008) Data suggests that components in coffee including diterpenes, cafestol and kahweol, caffeine and chlorogenic acid may be responsible for the beneficial effects. (Tao et al. 2008) In 2005 Japanese researchers published their findings after conducting a large-scale population based study that confirmed a statistically significant inverse (protective) association between habitual coffee drinking and liver cancer. (Inoue et al. 2005) A more recent Japanese study also found coffee drinking to be associated with a decrease in liver cancer risk. (Ohishi et al. 2008) These findings were supported by a hospital based study in Italy (Anese et al. 2003) and further endorsed by the publication of a pooled analysis of data consisting of over 60,000 people, which also found a significant inverse association between coffee consumption and the risk of liver cancer. (Shimazu et al. 2005) Research continues in this area. Conclusions from two meta-analyses strengthen the associated protective effect of coffee drinking on liver cancer. (Bravi et al. 2007., Larsson et al. 2007) The results of a large population-based study found a significant inverse association between coffee drinking and liver cancer. (Hu et al. 2008)
