Francisco Guarner, director of the Digestive System Research Unit at University Hospital Vall d’Hebron in Barcelona (Hospital Universitario Vall d’Hebron), granted us an interview during the 4th Gut Microbiota for Health World Summit 2015 to discuss the microbiota and humans. In the interview, Guarner, who chaired the event’s Science Committee, uses clear and short concepts to summarize what the microbiota is, its purpose and its relationship with different conditions and disorders.

This video helps us reflect on our internal bacterial ecosystem and reminds us that taking special care of our microbiota is an essential task for all.
