6、Calorie-Free Soft Drinks May Make You Fat 无热量饮料也可能让你发胖

I've never been a big fan of diet drinks (I prefer good old water), and now I'm glad. A study conducted by the University of Texas Health Science Center at San Antonio followed over six hundred people ranging from twenty-five to sixty-four years old for up to eight years and found that those drinking diet soda — even as little as one can or bottle a day — did not lose weight and were significantly more likely to become overweight than those who drank regular soft drinks or none at all. How can this be? No one knows for sure, but scientists think that artificial sweeteners, perhaps even the caramel coloring, may muddle brain chemistry. The brain in a sense gets a reward, and the desire for more sweets is intensified. The more of these fake sweet products you eat or drink, the more sweets you want.

我对节食饮料从来不热衷，只喜欢纯水，如今我深感庆幸。位于圣安东尼奥的德克萨斯州立大学健康科学中心对年龄层在25-64岁的600人进行了八年的研究，发现那些喝减肥汽水的人，及时他们只喝一点点、一天只喝一瓶，并没有比喝普通饮料或完全不喝饮料的人有显著的减肥效果。这是为什么？没人知道答案，但科学家们认为人工甜味剂甚至焦糖色素可能对大脑化学造成紊乱。大脑得到一个鼓励信号，吃更多甜食的想法被强化。你吃喝的假甜食越多，你就会越想吃甜味的东西。
