As if I needed to reiterate the importance and pure goodness of coffee, science comes along and has revealed that coffee drinkers have a lower risk of liver cancer. As a caveat, I'm not sure if this statistic includes alcoholic coffee drinkers, as the combination of the two may cancel the effect.

Researchers in Japan studied more than 90,000 Japanese coffee drinkers. The discovey was that those who drank coffee daily, or nearly every day, had half the liver cancer of the control group. The protective effect occurred in people who drank one to two cups a day, and increased with three or four cups.

Coffee contains large amounts of antioxidants, and several other studies have shown that those compounds have the possibility to prevent cancer in the liver. Additionally, skin creams with caffeine as an ingredient are shown to reduce skin cancer in mice. The Japanese study also examined green tea, but no connection was found between liver cancer and comsumption of green tea.

So feel better when sipping your daily cup of joe, because you'll be doing something nice for your liver!
