#59 - The gut microbiome in health and sport with Dr Orla O'Sullivan

Dr Glenn McConell chats with Dr Orla O’Sullivan from the Teagasc Food Research Centre, from Ireland. She is a research expert effect of diet and exercise on the gut microbiome (the types of cells in the gut microbiome based on the DNA measurements). She has looked at the gut microbiota in rugby players, cricketers, ironman and other sports. She emphasized the importance of having a diverse gut microbiome. This is a very good episode to extend upon the episode on gut microbiota and exercise with Dr Edward Chambers (podcast episode #57). Very interesting work and a fun chat. Twitter: @OrlaOS.0:00.
