 This is scientific American 60 seconds science. I am, got a minute? Everywhere you go, the trillions of microbs is in you got go to. That is a compllicating sort, because according to a new study a more diverse population of testnal bacteria is links to better health. The work is in the journal nature.   researcher gather got microbs for almost 300 tribillion micros in obese or non-obese adults. The testines of roughly one in four participants contains fewer and less diverse bacteria than average. And members of this group are more likely to bobs or suffer from to got-infammation. By looking for only a few specific bacteria researchers could predict whether a subject ferlent in low diversity group. Certain species could even indicate wheter an individial were slim overweight. And these microbremarkers were also severe science for future health risks. Because low diversity participant to world obese were likely to gain additional way overtime. But low diversity got woundn't necessarliy do me a health. According to another study in the same journal, it is possible to increase the microbs diversity by developing a decent diet. Rember you are reading for trillions.
