咖啡对肝脏极有好处

The liver is a remarkable organ that carries out hundreds of vital functions in the body. It is very vulnerable to modern insults such as excess consumption of alcohol and fructose. Cirrhosis is the end stage of liver damage caused by diseases like alcoholism and hepatitis, where liver tissue has been largely replaced by scar tissue. Multiple studies have shown that coffee can lower the risk of cirrhosis by as much as 80%, the strongest effect for those who drank 4 or more cups per day. Coffee may also lower the risk of liver cancer by around 40%.

咖啡能降低死亡率

Many people still seem to think that coffee is unhealthy. This isn't surprising though, since it is very common for conventional wisdom to be at exact odds with what the actual studies say. In two very large prospective epidemiological studies, drinking coffee was associated with a lower risk of death by all causes. This effect is particularly profound in type II diabetics, one study showing that coffee drinkers had a 30% lower risk of death during a 20 year period.
很多人还是觉得咖啡不健康。这也不奇怪，真理刚被提出时，总会被怀疑是谬论。在两大前瞻性流行病研究中，喝咖啡能降低各种原因的死亡率。对二类糖尿病中的效果也极其明显，研究表明20年来咖啡饮用者降低了30%的死亡率。

Bottom Line: Coffee consumption has been associated with a lower risk of death in prospective epidemiological studies, especially in type II diabetics.
总结：在前瞻性流行病研究中发现，咖啡能降低死亡率，尤其是二类糖尿病。
