[参考译文]5年前人类肥胖基因的发现提供了证据,从生物学的角度,证明了慢性体重增长是营养和身体本能不协调的结果。把肥胖归咎于脂肪消耗减少这样的解释过于简单,且忽略了科学实质。在许多国家,如印度或中国,直到引进了高脂肪西式饮食,肥胖症这个概念才为人所知。一个广为人知的原因是,食物中的脂肪比蛋白质或碳水化合物更易转化为身体中的脂肪。不过最近科学家发现一个看来同等重要的因素。一些大学学者在研究是否过量 The discovery of the human obesity gene five years ago provided evidence that, from a biological point of view, chronic weight gain is the result of uncoordinated nutrition and physical instincts. Attributing obesity to a reduction in fat consumption is too simplistic and ignores scientific substance. In many countries, such as India or China, the concept of obesity is not known until the introduction of a high-fat Western diet. One of the best known reasons is that fat in food is more easily converted to fat in the body than protein or carbohydrates. But recently scientists have found a factor that seems equally important.
