The ‘Gut Microbiota & Health Section’ of the European Society Neurogastroenterology and Motility (ESNM), has released the Spanish version of the "http://www.metahit.eu/index.php?id=410" Gut Microbiota Worldwatch web. The web’s aim is to bring closer the importance for health and life quality of the gut microbiota (or intestinal bacteria) to the society and the media, and of course, to expand the knowledge about the issue. The Gut Microbiota Worldwatch’s President is Dr. Fernando Azpiroz, head of the Physiology and Pathophysiology of the Digestive Tract group at Vall d’Hebron Institute of Research (VHIR), and also head of the ESNM Gut Microbiota & Health section, member of the UEG-United European Gastroenterology. Dr. Azpiroz emphasizes that “it is important for people to know the activity of the universe of bacteria they host in their guts and its key role for many physiological functions that our body is not capable of doing by itself, as some fiber digestion or some vitamin production, among others”. He also assures that if we care about our intestinal microbiota “it will take care of us, helping us protect our health and life quality”.Secondly, Dr. Francisco Guarner, researcher of the same group in VHIR, is a member of the experts’ board, contributing with his knowledge in the fields of intestinal mucosa, inflammatory bowel disease and probiotics, among others. He is the leader of the MetaHit Project in Spain whose goal is to associate bacterial genes with human health and diseases.The web is a powerful and extensive source for gut microbiota information online, with content selected from this experts’ platform and adapted for easier accessibility for a non-scientific audience.
