问题    Think this way, it’s your inability to resist cheesecake that’s making it tough to fit into your skinny jeans? Well, a new study shows your bacteria may share some of the blame.
   Because the new study in mice reveals that the response of intestinal microbes to a high-fat diet ends up triggering the release of a hormone that makes mammals feel hungry, causing them to eat even more. The finding is served up in the journal Nature.
   Previous work has shown that the types of bacteria in the gut in diabetic or obese individuals are different from the bacteria in healthy people. But does this bacterial makeup contribute to these disorders? Or is it just a side effect?
   To unravel this mystery, researchers put mice on a high-fat diet. As a result, the animals experienced a buildup of a chemical called acetate (醋酸盐), particularly in the large intestine.
选项
答案 设想一下，你很难穿上紧身牛仔裤是因为你无法抗拒奶酪蛋糕的缘故吗?其实，你体内的细菌可能要承担部分责任。 一项在小鼠身上进行的新研究表明，肠道细菌对高脂肪饮食的反应会最终引发荷尔蒙的释放，使哺乳动物感到饥饿，导致它们吃得更多。该项发现已经刊登在《自然》杂志上。此前的研究表明，糖尿病患者或者肥胖群体肠道中的细菌类型与健康人的不同。但是这种细菌组成会导致这些疾病吗?还是只是一种副作用? 为了解开这个谜团，研究人员让小鼠食用高脂肪饮食，结果发现动物体内会生成一种名为醋酸盐的化学物质，这种物质尤其会堆积在大肠中。
