近年来,许多研究都指出咖啡具有健康效益,提出咖啡或可预防2型糖尿病,降低总体死亡率,甚至可能有助于防止痴呆症的发生。还有其它研究表明,咖啡可能会降低包括结肠癌在内的某些癌症的风险。这些优点通常都被归因于咖啡的抗氧化和抗炎特性。
But as with many studies about diet, proving a link between coffee consumption and protection against cancer recurrence is difficult.
然而,关于饮食的研究虽多,要证实饮用咖啡与预防癌症复发之间的关联却十分困难。
"Think about it: People who drink a lot of coffee tend to be high stress, high pressure, intense and compulsive," said Dr. Alfred Neugut, a professor of cancer research, medicine and epidemiology at Columbia University and a director of NewYork-Presbyterian Hospital's Cancer Prevention Center. "If they have cancer, they're going to be more obsessive about following all the rules and doing all the things they're supposed to do. So it may be that coffee itself is playing a physiological role, but it may also be a surrogate marker for you being a compulsive health-conscious good behaver."
"想想看:大量喝咖啡的人往往压力比较大、容易紧张或有强迫倾向,"美国哥伦比亚大学的癌症研究、医学和流行病学教授,纽约长老会医院癌症防治中心的主任艾尔弗雷德·纽各特博士说。"如果他们患了癌症,肯定会更严格地遵循所有的规则,去做所有他们应该做的事情。因此,或许确实是咖啡本身发挥了什么生理作用,但也有可能爱喝咖啡只是特别注重健康行为的人们的一个替代性标识。"
