Science Friction

03 | Cooked: Mystery in the MediterraneanIt was one of the world's biggest nutrition trials. A study of thousands of people which found that following a Mediterranean diet could meaningfully reduce someone's risk of heart disease and stroke. But as data detectives began to comb through the results of the trial, something wasn't quite adding up. On Cooked this week, we're taking a look at what can go wrong when implementing a nutrition science trial at scale ... and what it means for one of the world's most popular diets. Guests: Dr John Carlisle Anaesthetist, NHS, United Kingdom Dr Gideon Meyerowitz-Katz Epidemiologist, University of Wollongong Dr Evangeline Mantzioris Program Director, Nutrition and Food Sciences, University of South Australia Credits: • Presenter: Dr Emma Beckett • Producer: Carl Smith • Senior Producer: James Bullen • Sound Engineer: Angie Grant This story was made on the lands of the Gadigal, Wurundjeri, Jagera and Turrbal peoples.

05 | Cooked: Electrolytes — who needs them?Over the past few years, you might have heard advertisements in your podcast feed or on social media for electrolyte supplements. If you haven’t seen them, they’re basically these little sachets or tubs that get mixed in with water as a drink. News media reports demand for such products is exploding – with the market for electrolyte supplements set to grow to 112 billion dollars by 2030, more than doubling in size in less than a decade. They go by a bunch of different names … and their marketing often suggests we could all use more electrolytes in our life. But what’s the science on this swing towards salty beverages? Who actually needs them? And what does our obsession with optimised hydration … say about us?
