Staying Healthy Takes Guts Full of Microbes

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.

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.

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.

通过观察几种特定细菌,研究人员能预测研究对象是不是属于微生物低种类组_IB4Q258mfvsiK8(;PY。特定的微生物甚至能预测个体是苗条还是肥胖c]KYuEfb31)kMy4j。这些微生物也能提供未来健康风险的标志,因为体内微生物种类低的肥胖研究对象更有可能变得更肥胖2UohXkMde[ifUu3!FXx

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.
