Just the opposite. Numerous studies have shown that coffee is associated with impressive health perks. It's been linked to lower risk of heart disease, Parkinson's, and liver cancer -- and it might even help you live longer. In fact, a recent study in the American Journal of Epidemiology found that people who drank coffee had a lower risk of death over the course of 11 years compared with those who skipped joe altogether.

恰恰相反。許多研究表明，咖啡對健康大有好處。它能減少心臟病、帕金森癥和肝癌的發病風險——甚至可能幫你活得更久。實際上，美國流行病學期刊最近的一項研究發現，在11年里，喝咖啡的人比完全不喝咖啡的人死亡風險更低。
事實糾正：有人認為運動前喝咖啡會讓你脫水。事實上，有研究表明，咖啡的利尿作用并不會發生在運動中。
