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 (either saccharin, sucralose, or aspartame) developed marked glucose intolerance. They focused on saccharin for the next series of experiments, since it was associated with the most pronounced response. For mice on a high-fat diet, those consuming saccharin showed glucose intolerance compared to those consuming glucose. The groups had similar food and liquid consumption and energy expenditure. Next, the researchers did two things to test whether the microbiota were responsible for…

A panel of scientific experts* assembled in London, UK, on October 23, 2013 to discuss the scope and appropriate use of the term ‘probiotic.’ The International Scientific Association for Probiotics and Prebiotics (ISAPP) organized the meeting to review the relevance of the 12-year-old FAO/WHO definition of probiotics: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host" (FAO/WHO 2001). This consensus panel was motivated by these recent developments: In the European Union, in the absence of approved health claims for probiotic foods, the word ‘probiotic’ is considered a health claim. Consequently, several countries have determined that the word can no longer be used on foods.…

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…

Dr. James Versalovic, M.D., Ph.D, is the director of the Texas Children's Hospital Microbiome Center and head of the Pediatric Infectious Diseases Section. He is also a professor at Baylor College of Medicine. As the Gut Microbiota for Health expert on research tools, Dr. Versalovic spoke with us about his pathology and immunology research related to the gut microbiome. How did you become interested in studying the gut microbiome? In graduate school as an M.D./Ph.D. student at Baylor College of Medicine here in the U.S., [I] was very interested in how microbes cause infections. That was a main clinical area of interest. And when I moved to Boston to continue my training, we were studying mouse models…
