中国的一项研究显示,肥胖可能由细菌感染引发,而不是过度饮食、锻炼太少或者是遗传因素。研究人员将与肥胖有关的人类细菌喂给老鼠,将它们的体重增加,并与没有喂细菌的老鼠进行比较。尽管后者被喂食高脂肪食物并被阻止锻炼,却没有出现肥胖症状。这一研究还引出了另外的问 A Chinese study shows that obesity may be caused by bacterial infections rather than over-eating, exercising too little or being a hereditary factor. Researchers fed obese human bacteria to mice, increased their body weight, and compared them to non-bacteria fed mice. Although the latter was fed high-fat foods and was prevented from exercising, no obesity symptoms occurred. This research also raises another question
