1) In the research article titled Symbiotic gut microbes modulate human metabolic phenotypes written by Zhu Chen from Shanghai’s Second Medical University, a group of scientists studied the different types of microbes that exist in seven test subjects and compared their metabolic phenotypes. 2) Chen provided evidence that each test subject had a unique colony of micro bacteria within their gut and the Bacteroidetes-to Firmicutes ratios between them all correlated with obesity. 3) The purpose of this paper was to study the effect of bacteria within our bodies that leads to certain diseases in order to gain knowledge about how to prevent/treat these diseases. 4) This scientific article is intended for those who want to create pharmaceutical drugs to treat obesity and other diseases that deal with the gut micro biome.
