#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.

[@Canada_Kasthuri]

It was an informative session, prof! 🎉

[@Jhumanghjngg]

Maybe road cycling is concentric only. MTB is huge in eccentric contractions, though. The rougher the decent, the more.

[@insideexercise]

True. Thanks for pointing that out. I’ll remember that going forward.

[@Kernoe]

laughable! sorry! I like a lot how science testing is actually lost on good gut health. Schadenfreude on my part. Probiotics and fermentable fibers! ha ha ha

[@insideexercise]

Sorry. What are you saying here?

[@Kernoe]

@@insideexercise Sorry, what was i saying. I take back the science from the testing and the many statements that were drawn from associations and hypotheses how people should it as diverse as possible and fiber rich. Out of my own health experience i am quite on the opposite side of that argument, got rid of weight and asthma bronchialis after 34 years and just by the look of things do not see this very nice woman and not curious enough scientist, as in the role to inform the public on how to eat. Hope i stayed kind enough this time. It would clearly help if in testing hypotheses one does not try to prove points such as how important short chain fatty acids from gut fermentation are, the overly important role of fiber or the divers microbiome but stays at a neutral point and tries to judge accordingly. I am just tired of hearing the same things over and over again which still have to be proven vital and essential by science.
