今日长难句
While plain water is the healthiest source of water, Ritchieson says any non-alcoholic drink makes a contribution. When, in 2016, researchers at the University of Stirling monitored water levels in students for four hours after taking on different liquids, they found that a litre of instant coffee—and even beer—was as hydrating as the same amount of water. But water levels remained highest of all, above water even, after drinking milk.

在社交媒体上吹嘘每日喝水的升数已经成了名人的一种荣誉徽章，詹妮弗·安妮斯顿和格温妮丝·帕特洛都表示自己每天能喝3升水。但不是每个人都会觉得喝水这么容易。不少人觉得喝白水太“枯燥”，而且频繁上厕所也颇浪费时间。英国国家医疗服务体系的指导原则建议成人的日摄水量应控制在6至8杯之间，相当于2升。虽然这是大家熟知的8杯水标准，但实际上非常少的实证研究支持这个数字。
