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。
Verdict: If you want a perfect smile, coffee may be the lesser of two evils.
