6、Calorie-Free Soft Drinks May Make You Fat 無熱量飲料也可能讓你發(fā)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.

我對節(jié)食飲料從來不熱衷，只喜歡純水，如今我深感慶幸。位于圣安東尼奧的德克薩斯州立大學(xué)健康科學(xué)中心對年齡層在25-64歲的600人進(jìn)行了八年的研究，發(fā)現(xiàn)那些喝減肥汽水的人，及時他們只喝一點點、一天只喝一瓶，并沒有比喝普通飲料或完全不喝飲料的人有顯著的減肥效果。這是為什么？沒人知道答案，但科學(xué)家們認(rèn)為人工甜味劑甚至焦糖色素可能對大腦化學(xué)造成紊亂。大腦得到一個鼓勵信號，吃更多甜食的想法被強(qiáng)化。你吃喝的假甜食越多，你就會越想吃甜味的東西。
