Staying Healthy Takes Guts Full of Microbes
保持健康需要腸道里充滿微生物。
Everywhere you go, the trillions of microbes in your gut go too. And that's a comforting thought. Because according to a new study, a more diverse population of intestinal bacteria is linked to better health. The work is in the journal Nature.
你去任何地方，你腸道中的數萬億微生物也跟著去任何地方。這是個令人欣慰的想法。因為根據最新的研究，更多的腸道微生物意味著更好的健康狀態。這份研究發表在《自然》雜志上。
Danish researchers gathered gut microbes from almost 300 obese and non-obese adults. The intestines of roughly one in four participants contained fewer and less diverse bacteria than average. And members of this group were more likely to be obese and to suffer from gut inflammation.
丹麥研究人員從300名肥胖和非肥胖成年人腸道中收集了微生物。每四個參與者中有一個的腸道微生物數量低于平均值。這些低于平均值的人更傾向于肥胖，并且有腸道感染。
By looking for only a few specific bacteria, researchers could predict whether a subject fell into the low-diversity group. Certain species could even indicate whether an individual was slim or overweight. And these microbial markers might also serve as signs of future health risks—because low-diversity participants who were obese were more likely to gain additional weight over time.
通過觀察幾種特定細菌，研究人員能預測研究對象是不是屬于微生物低種類組。特定的微生物甚至能預測個體是苗條還是肥胖。這些微生物也能提供未來健康風險的標志，因為體內微生物種類低的肥胖研究對象更有可能變得更肥胖。
But a low-diversity gut won't necessarily doom your health. According to another study in the same journal, it's possible to increase microbial diversity by developing a decent diet. Remember, you’re eating for trillions.
但是腸道微生物種類低不一定說明健康狀況不好。根據該雜志上另一項研究顯示，通過適當的飲食可以增加微生物種類。記住，你是為健康而食。
