In episode 26 of Science & Chill, I interview Kevin Bass, who has been on my “to interview” list for quite some time, and we were able to finally make some time to record this episode. If you aren’t familiar with Kevin, he is a scientist and also a truth-seeker, experimenter, expert, and social-media presence in the area of nutrition. Kevin has become low-key famous on Twitter and elsewhere for his rants about nutrition and his recently scrutinized “quack list” — topics that we discuss in this episode along with much more.

In this episode of Science & Chill, I interview Matt Fitzgerald. Matt is an author, endurance sports coach, and certified sports nutritionist whose work has appeared in national publications including Bicycling magazine, Maxim, Men's health, and Outside magazine. Matt has written several popular books on the science and art of running and endurance sports including 80/20 Running, Racing Weight, How Bad Do You Want It, Diet Cults, Running the Dream, and his most recent book, The Comeback Quotient.

I wanted to interview Matt to talk about his writing and running, but the main reason I asked him to come on the podcast was to discuss his recent struggle with what is being referred to as post-acute covid-19 syndrome (PACS) — the constellation of physical and mental symptoms that seem to arise months after one has suspectedly or certainly been infected with the COVID-19 virus. This is exactly what happened to Matt, who suspects he contracted COVID sometime in March of 2020, but didn’t start to experience severe COVID-related effects until nearly 6 months after his stint with the virus. In this podcast, he details how his athletic and personal life have been impacted by post-acute COVID syndrome and an alarmingly slow to nonexistent recovery. In some respects, he thinks he only seems to be getting worse. 

 

I’m excited to announce that this podcast is being brought to you by LMNT electrolyte drink mix. If you haven’t heard of LMNT, you probably will soon. LMNT is the best electrolyte supplement out there, and I swear by this stuff for fueling and helping me recover from my workouts. I had a packet during and after my indoor cycle this morning and feel considerably better than if I was drinking just water. 

LMNT electrolytes are way different than other electrolyte drinks or drink mixes on the market. It contains zero sugar, no fillers or artificial ingredients, and is completely free of food allergens like gluten. The electrolyte content of LMNT is also what separates it from other products: each packet contains 1000mg of sodium, 200mg of potassium, and 60mg of magnesium. Right now I’m alternating between  orange, raspberry, citrus salt, and even their chocolate flavors, and they’re all insanely tasty.

 

Right now, LMNT has a special offer for all Science & Chill listeners. You can get a free LMNT sample pack, just pay the $5 price for shipping. In the sample pack, you’ll get 2 packets each of their citrus salt, orange, raspberry, and raw unflavored salt. This gives you an opportunity to try out LMNT and see the performance and health benefits for yourself. Again, this is hands down the best electrolyte drink mix I’ve tasted and the only one I’ll ever purchase again. To claim this offer, go to DrinkLMNT.com/ScienceandChill.

In this episode of the Science & Chill podcast, I speak with Dr. Elisabeth Bik.

Dr. Bik is a microbiome scientist and science integrity advocate. She received her PhD from Utrecht University in the Netherlands. Her scientific work has included time at the Dutch National Institute for Health and the Stanford University School of Medicine. She is the creator of Microbiome Digest, a blog where she posts almost daily papers published in the area of the microbiome. She has also held roles as a science editor and scientific and editorial director at uBiome, and director of science at Astarte medical.

Currently, Dr. Bik is devoting her work to being a full-time Microbiome and Science Integrity consultant. Her work has been featured in major news publications including Nature, the New York Times, the Washington post, Le Monde, The Scientist, and more. She often shares her detective work on social media with the hashtag #ImageForensics, and she has nearly 85,000 Twitter followers.

In this episode, we talk about the microbiome -- what what the microbiome is, the functions of the microbiome in human physiology, how the microbiome might be responsible for obesity and other modern-day diseases, and how diet, lifestyle, and our environment influence the microbiome. 

The majority of our conversation surrounds her main role as a "science integrity consultant." Dr. Bik regards herself as a "scientific sleuth" in the area of image duplication, where she uses her own two eyes to spot potentially fraudulent or duplicated imaged within scientific papers. Her investigations have led to published papers and the reporting of her findings to major scientific journals, resulting in the correction and/or retraction of several papers.

The work Dr. Bik does is important and I believe, somewhat underappreciated. What she's doing really is impactful and integral to upholding the integrity of science and keeping the "checks and balances" of scientific publishing in tact.

I hope you enjoy this episode!

In episode 23 of Science & Chill, I speak with Dr. Nick Greiner. 

 

Dr. Greiner is trained and certified as a functional medicine physician who practices out of Pittsburg, Pennsylvania. His clinic focus on regenerative medicine therapies and he advocates using lifestyle interventions such as diet and exercise to improve patients' health. 

 

In this episode, we talk about his practice, his philosophy on healthcare and how he tackles health from an integrative approach. We also dig in to some "biohacking" and talk about light and circadian rhythms, heat/cold exposure, and intermittent fasting.

In episode 22 of the Science & Chill podcast, I have a conversation with one of my great friends and fantastic scientist, Ravi Kumar. 

 

Ravi is a PhD student in the department of Applied Physiology and Kinesiology at the University of Florida (we share a building!). 

 

His lab focuses on the effects of dietary nitrate supplementation on muscle function and also conducts research in animal models of heart failure. Ravi recently published an article in the Journal of Physiology showing that nitrate supplementation improves respiratory muscle function in rodents, and we talk a bit about that paper in this podcast. 

 

In addition to talking about his research, we geek out on endurance sports, which is a frequent topic of conversation between Ravi and I.

In Episode 20 of Science & Chill, I speak with Dr. Henry Henderson. 

 

Dr. Henderson is a post-doctoral fellow in the department of Hematology/Oncology. His research focuses on understanding non-small cell lung cancer and improving therapeutic strategies targeting oncogenic mutations in Epidermal Growth Factor Receptor (EGFR) tyrosine kinase domain with a particular focus on mechanisms of sensitivity and resistance to agents used in clinical practice.

 

Dr. Henderson is also the co-founder of Black in Cancer, an organization that began this year with the goal of "Strengthening Networks and Highlighting Black Excellence in Cancer Research and Medicine."

 

We talk about issues regarding race in academia, medicine, and health disparities. We also talk about Dr. Henderson's research on cancer biology and some exciting projects he's working on. I had a great time speaking with him and I hope you enjoy listening to our conversation.
