14、却后饮用或能避免某些癌症。其实，联合国癌症研究机构决定将热饮与铅、汽油及废气一同列入“潜在致癌”的名单中。也就是说，这些东西都存在诱发癌症的风险。国际癌症研究机构（IARC ）是世界卫生组织的分支。国际癌症研究机构将这一研究成果刊登在柳叶刀肿瘤学杂志上。国际癌症研究机构的研究人员称，有证据表明温度超过 65 度的饮料可能会引发食道癌。研究人员检验了其它研究的结果，这些研究称，茶和咖啡通常都是在不低于 70 度的情况下被端上桌的。这些研究是在伊朗、中国和南美洲完成的。发达国家的卫生专家认为食道癌与吸烟、饮酒有关。但是食道癌在习惯饮用高温饮料的地区更为常见。在欧洲和美国，很多人都会饮用 60 度左
15、右的咖啡和茶。而且他们会往饮品中添加牛奶来降低温度。然而，伊朗的茶爱好者与南美洲马黛茶爱好者通常会饮用 70 摄氏度左右的茶饮。马黛茶是一种将巴拉圭叶子浸泡在沸水中的类似于茶的饮品。研究人员指出，南美洲人不但喝高温的马黛茶，还用金属吸管饮用。通过吸管让热饮直达喉咙。然而，对于那些喜爱咖啡的人来说，这无疑是个好消息。1991 年，世界卫生组织将咖啡列入“潜在致癌”的名单中，但是之后又将咖啡从“潜在致癌物”名单中剔除。如今，他们声称饮品温度的危害远大于饮品本身。克里斯托弗维尔德（Christopher Wild）是国际癌症研究机构的主管。他对 AFP 通讯社称，研究结果表明， “饮用高温饮品可能引发食道癌，原因在于温度而不在于饮品本身，这一点似乎是可信的。 ”美国国家咖啡协会称，这一改变“对喜饮咖啡的人来说是个好消息” 。食道癌究竟有多常见？食道癌是全球第八大常见癌症。2012 年，约 40 万患者死于食道癌。安娜马特奥为您播报。
