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.

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

Jens Walter PhD

Episode 135 of the Institute of Performance Nutrition's "We Do Science" podcast! In this episode, I (Laurent Bannock) discuss "The Microbiome" with Dr Jens Walter PhD (University College Cork, Ireland) and Dr Orla O'Sullivan PhD, Teagasc Food Research Centre, Ireland).  Discussion Topics Include:  The Microbiome: An overview Lifestyle-induced microbiome depletion and impact on health The "Fibre Gap": Low-fibre diet as a key driver of microbiome depletion Establishing what constitutes a healthy human gut microbiome: state of the evidence and translational issues Environmental, clinical, and nutritional factors and the microbiome Exercise and associated dietary extremes impact on gut microbial diversity  Key Paper(s) Discussed / Referred to:  Establishing What Constitutes a Healthy Human Gut Microbiome: State of the Science, Regulatory Considerations, and Future Directions The Fiber Gap and the Disappearing Gut Microbiome: Implications for Human Nutrition The microbiome of professional athletes differs from that of more sedentary subjects in composition and particularly at the functional metabolic level Exercise and associated dietary extremes impact on gut microbial diversity  Related Podcast Episodes:   Episode 63 - 'Probiotics and Athletes' with Professor David Pyne Episode 69 - 'Immunological Aspects of Training &amp; Sports Nutrition' with Professor Michael Gleeson  Check out our other podcasts, publications, events, and professional education programs for current and aspiring sports nutritionists at www.TheIOPN.com and follow our social media outputs via @TheIOPN

#135 - "The Microbiome: Mind the Gap" with Jens Walter PhD and Orla O'Sullivan PhD

Before we get to the show notes please consider donating to Australian charities and organisations as a show of support for the disaster relief. The Australian bushfires have significantly eclipsed the environmental effect of both the recent Californian and Amazon fires. The relief effort will take years and the environment in the affected areas may never be the same. More than one hundred fires still burn around the country, as both people and wildlife are displaced or killed.   Below are the links for RFS NSW and the Red Cross if you’d like to learn more about the situation or have the capacity to donate - it all counts.   RFS - https://www.rfs.nsw.gov.au/volunteer/support-your-local-brigade Red Cross - https://fundraise.redcross.org.au/drr   Thank you for the support, from all over the world! ------------------------------------   Today’s episode features the gut health whizz, Dr Orla O’Sullivan. Orla is a Research Fellow in Teagasc Food Research Centre, Moorepark and graduated from UCC with a BSc in Biochemistry and subsequently a PhD in Bioinformatics. Her research focuses on elucidating the microbiome from various environments including human gut and lung, rumen and food. Of particular interest to her is the role of exercise and diet, specifically whey protein, on the human gut microbiome both in healthy and diseased cohorts. Orla also has a keen interest in Science communication and sits on the education and outreach committee of the APC.   Orla was recently awarded the early career researcher of the year award from the Science Foundation of Ireland, and today Mark talks to Orla about the benefits to high performance athletes of promoting diversity in microbiome for gut health.   A fascinating discussion including real world examples from her work with the Irish Rugby Union team. Let us know what you think or if you’d like to hear more about gut health from another expert around the world!   Train Smarter with Science is brought to you by Velocity Performance.
