无糖饮料到底能不能喝？英国利物浦大学的科学家完成了迄今规模最大、时间最长的相关随机对照试验。研究招募了493名超重或肥胖的成年人，所有人都参加减重项目，一半人每天喝水，另一半人每天喝无糖饮料。两年后，两组减重效果几乎一样：无糖饮料组平均减了4.8公斤，喝水组减了3.7公斤，差异小到没有统计意义。两组的血压、胆固醇和体成分都有改善。研究者表示，"甜味剂扰乱食欲、危害健康"的担忧在这项严格的长期试验中并未得到支持。想戒糖又舍不得快乐水？换无糖版本，效果可能和喝水一样好。这项研究发表在《英国营养学杂志》上。

## 全文参考
Here is some good news for anyone who loves diet soda. A major new study says diet drinks work just as well as water for losing weight. Researchers at the University of Liverpool in the U.K. ran the longest study of its kind. They followed four hundred ninety-three adults for two years. Everyone joined a weight-loss program. Half drank water every day. The other half drank diet drinks with no-calorie sweeteners. After two years, both groups lost about the same amount of weight. The diet drink group lost four point eight kilograms, and the water group lost three point seven. The difference was too small to be meaningful. Both groups also saw better blood pressure and cholesterol. The researchers say the fear that sweeteners harm your health is not supported by this trial. So if you are trying to cut sugar, swapping soda for a diet version may be just as good as water.
