Mikkipedia is an exploration in all things health, well being, fitness, food and nutrition. I sit down with scientists, doctors, professors, practitioners and people who have a wealth of experience and have a conversation that takes a deep dive into their area of expertise. I love translating science into a language that people understand, so while some of the conversations will be pretty in-depth, you will come away with some practical tips that can be instigated into your everyday life. I hope you enjoy the show!

Omega-3s Unpacked with Greg Peoples
Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to omega-3 expert Greg Peoples to unpack the science behind these essential fats and their impact on health and performance. They discuss the differences between DHA, EPA, and pro-resolving mediators (SPMs), the best dietary sources—including the surprising mention of tuna—and what an optimal Omega-3 Index looks like. Greg also explains whether we can reach ideal levels through diet alone, or if supplementation is necessary.They dive into omega-3s for athletes, covering their role in endurance performance, recovery, and even potential protection against atrial fibrillation in older endurance athletes. Greg breaks down their effects on muscle soreness, strength, and neuroprotection in contact sports, as well as the emerging link between omega-3s and sleep quality. Finally, they tackle supplement quality—how to choose a trustworthy brand in the wake of past industry scandals. A must-listen for anyone looking to optimise their omega-3 intake!Associate Professor Gregory Peoples is a distinguished cardiorespiratory physiologist with over two decades of experience in researching and communicating the physiological roles of omega-3 fatty acids, particularly EPA and DHA, in optimising heart, muscle, and brain performance and recovery.Based at the University of Wollongong, A/Prof Peoples has contributed significantly to understanding how dietary long-chain omega-3 polyunsaturated fatty acids, especially DHA, influence skeletal muscle physiology and function. He leads Ω3 Performance Physiology, a company dedicated to exploring the benefits of omega-3s in athletic performance and recovery.Throughout his career, A/Prof Peoples has authored numerous high-impact papers on omega-3s, and his research has been instrumental in translating bench-top science into practical applications for both the general population and specialised groups, including elite athletes and military personnel. His work continues to influence dietary recommendations and therapeutic interventions aimed at enhancing physiological function and overall health.Greg: https://scholars.uow.edu.au/greg-peoples

The Truth About Vaping: Science, Safety & Public Health with Dr. Paul Reynolds
Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz or www.curranz.co.uk to order yours This week on the podcast, Mikki speaks to Dr Paul Reynolds about the effects of vaping on health, particularly its impact on inflammation, cancer risk, and pregnancy outcomes. Dr Reynolds, whose background is in lung development and disease, has been investigating how e-cigarettes influence inflammatory pathways, glycation, and long-term health risks.In this conversation, they discuss why breathing is more than just taking in oxygen and how air quality plays a critical role in overall health. Dr Reynolds explains glycation—how it damages the body—and how inflammation, often seen as a necessary defence mechanism, can sometimes do more harm than good.Mikki and Dr Reynolds delve into the chemicals found in e-cigarettes, comparing their inflammatory effects to traditional cigarettes. They explore whether vaping genuinely helps smokers quit or if it fosters new dependencies, as well as the risks of secondhand exposure and how vaping should be approached from a public health perspective.Dr Reynolds shares findings from his research on vaping during pregnancy, including its effects on foetal and placental weight, and the potential implications for conditions like intrauterine growth restriction (IUGR) and preeclampsia. They also discuss how e-cigarette flavours—such as Red Hot and Green Apple—can influence cancer cell invasion and inflammation, raising questions about whether some flavouring compounds should be restricted.With vaping still largely unregulated in many areas, Dr Reynolds offers insights into where research should focus next, what policymakers need to consider, and whether vaping should be treated with the same caution as smoking.This is a must-listen for anyone interested in the science behind vaping and its potential long-term health consequences. Enjoy the conversation!Dr Paul Reynolds is a professor in the Department of Cell Biology and Physiology at Brigham Young University, with a research focus on lung development, pulmonary disease, and the effects of environmental exposures such as tobacco and vaping aerosols on respiratory health. He holds a PhD in Developmental and Molecular Biology from the University of Cincinnati and has conducted extensive research on pulmonary injury, oxidative stress, and inflammatory pathways. His work examines how vaping impacts lung function, foetal development, and cancer progression, with recent studies exploring the role of e-cigarette flavours and nicotine in inflammation and disease risk. Dr Reynolds has received multiple awards for his research and teaching, including the Parker B. Francis Fellowship in Pulmonary Research, and is an active member of organisations such as the American Physiological Society and the American Thoracic Society.Dr Paul https://cell.byu.edu/directory/paul-reynolds
