Researchers from Israel recently published in Nature how NAS [Non-caloric artificial sweeteners] affect glucose tolerance. In an initial experiment, researchers found mice that consumed water, glucose, or sucrose had comparable glucose tolerance curves, but all 3 mouse groups consuming NAS

Patrick Veiga and MetaHIT colleagues tested how fermented milks product could modulate microbiota. Using a metagenomics approach, they found that the abundance of unknown species increased in the gut when patients took the fermented milk product. Having access to the

In Science Report journal, Zhang and colleagues published a study about Mongolians known to have their own typical lifestyle, notably in terms of dietary habits. Using 16S rDNA pyrosequencing, researchers showed the presence of a phylogenetic core microbiota comprising the

Marion Leclerc is a French microbiologist working at INRA  (the French National Institute for Agricultural Research) Jouy-en-Josas Centre. She spoke with Gut Microbiota for Health about her various areas of research. Research group of Marion Leclerc   What research are

Thirty organizations from fifteen countries are coming together to conduct gut microbiome research in a new project called MyNewGut. Professor Yolanda Sanz has been appointed MyNewGut's project coordinator and leads the project's human intervention trials on the gut microbiome's ability to metabolise nutrients

Numerous commensal bacteria present in the gut microbiota produce short chain fatty acids (SCFA’s) particularly acetate, butyrate and propionate. These SCFA’s have been associated with several biological effects upon host. Growing evidence suggests that specific microbes such as Faecalibacterium prausnitzii

Lawrence and colleagues tracked two subjects' microbiota over a year, collecting 800 fecal and saliva samples associated with 10,000 longitudinal measurements. They first highlighted the evidence for long-term, overall community stability, as differences between individuals were much larger than variation within

In an article published online on June 24, 2014 in the Journal of Clinical Investigation, Zhongyi Chen and Lilu Guo, from the Vanderbilt University, Nashville, Tennessee, USA, showed that the administration of a modified bacteria expressing therapeutic factors in the gut microbiota could reduce
