 　　everywhere you go ,the trillions of microbes in your gut¹ go,too.and that's a comforting thought,because according to a new study,a more diverse population of intestinal² bacteria is linked to better health. the work is in the journal Nature.Danish researchers gathered gut microbes from almost 300 obese³ and not obese adults. the intestines⁴ are roughly one in four participants contained fewer and less diverse bacteria than average.and the members of the group were more likely to be obese and to suffer from gut inflammation.but 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 individuals were slim or overweight.and these microbial markers might also serve a science of future health risks. because low-diversity participants who were obese were more likely to get additional weight overtime⁵.but low-diversity gut won't necessarily doom⁶ your health.according to another study in the same journal,it's possible to increase microbial diversity by developing a decent diet.remember, you are eating for trillions.
