Countless arguments have been waged over the superiority of one beverage over the other. But what does the scientific evidence say?
关于这两种饮料孰优孰劣的问题已经引发了无数争论。但是科学证据是怎样的呢?
George Orwell may have written that “tea is one of the mainstays of civilization in this country” – but even we British have to acknowledge that our national drink is facing stiff competition from the espressos, cappuccinos, and lattes invading our shores.
乔治·奥威尔或许写过“茶是这个国家文明的一个支柱”这样的句子——但我们英国人也要承认，随着浓咖啡、卡布奇诺和拿铁侵入国门，我们的全民饮料正面临着激烈的竞争。
Despite the dangers of wading into such a charged argument, BBC Future decided to weigh up the relative merits of each drink. There’s no accounting for taste, of course, but we have combed the scientific literature for their real, measurable effects on our body and mind.
尽管探讨这个敏感话题充满风险，“BBC未来”栏目还是决定对每种饮品的相对优点进行评估。当然，百人百味，但通过精心梳理科学文献，我们找出了它们对人体和大脑真实的、可测量的影响。
The wake-up call
醒脑剂
For many, the caffeine kick is the primary reason we choose either beverage; it’s the oil to our engines when we’re still feeling a bit creaky in the morning. Based purely on its composition, coffee should win hands down: a cup of tea has about half the dose (40 milligrams) of the stimulant caffeine that you would find in a standard cup of brewed filter coffee (80 to 115 milligrams). Yet this doesn’t necessarily reflect the jolt of the wake-up call.
对许多人来说，咖啡因的兴奋作用是我们选择这两种饮料的主要原因;在睡眼惺忪的清晨，咖啡因就像石油一样，给我们身体的引擎以能量。只考虑成分的话，咖啡可以轻松获胜：一杯茶的咖啡因含量(40毫克)大约只有标准杯过滤咖啡(80至115毫克)的一半。然而，这并非反映了它们的醒脑作用。
Dosing subjects with either tea or coffee, one study found that both beverages left subjects feeling similarly alert later in the morning.
通过让被试者饮用一定量的茶或咖啡，一项研究发现，这两种饮料都能让受试者在早晨晚些时候感到同样清醒。
Verdict: Against logic, tea seems to provide just as powerful a wake-up call as coffee. It’s a draw.
结论：虽然逻辑上讲不通，但茶跟咖啡的醒脑作用似乎不相上下。平局。
Sleep quality
睡眠质量
The biggest differences between coffee and tea may emerge once your head hits the pillow.
咖啡和茶之间最大的差异或许将集中体现在睡眠上。
Comparing people drinking the same volume of tea or coffee over a single day, researchers at the University of Surrey in the UK confirmed that although both drinks lend similar benefits to your attention during the day, coffee drinkers tend to find it harder to drop off at night – perhaps because the higher caffeine content finally catches up with you.
通过对比研究每天饮用等量的茶或咖啡的人，英国萨里大学的研究人员证实，尽管两种饮料在白天对注意力集中的作用差不多，但或许是因为咖啡里的咖啡因含量更高，喝咖啡的人晚上更难入睡。
Tea drinkers, in contrast, had longer and more restful slumbers.
相比之下，喝茶的人睡得更久更香。
Verdict: Tea offers many of the benefits of coffee, without the sleepless nights – a clear win.
结论：茶不仅拥有咖啡的许多好处，还不会带来不眠之夜——完胜
Tooth staining
牙齿变黄
Along with red wine, coffee and tea are both known to turn our pearly whites a murky yellow and brown. But which is worse?
众所周知，红酒、咖啡和茶都会把洁白的牙齿慢慢染成暗黄色或棕褐色。但哪个最糟糕?
Most dentists seem to agree that tea’s natural pigments are more likely to adhere to dental enamel than coffee’s – particularly if you use a mouthwash containing the common antiseptic chlorhexidine, which seems to attract and bind to the microscopic particles.
大多数牙医似乎一致认为，茶中的天然色素比咖啡的更易附着于牙釉质之上——尤其当你使用常见的洗必泰漱口水时，其中的消毒洗必泰能吸引并聚合微观粒子。
