Hacking Gratitude: Spartan World Championship Exclusive

Full Show Notes:https://bengreenfieldlife.com/rootsofhealth 

In this special "Best Of" episode, you'll explore some of my most impactful conversations on what actually builds long-term roots of health. If you're dealing with low energy, hormonal issues, chronic inflammation, or just a nagging sense that something's off despite doing all the right things, this episode gives you a clear roadmap.

You'll hear from Daniel Baird on why the synthetic fabric in your underwear may be quietly disrupting your hormones and why microplastics are becoming one of the biggest threats to male reproductive health, while Katy Bowman makes the case that your chair and mattress are doing more damage than you think. Justin Roethlingshoefer shares how a near-death diagnosis at 32 completely rewired his approach to health data and recovery. Dr. Cate Shanahan breaks down how the oils in your kitchen are being incorporated into your cell membranes. Julie Gibson Clark shows how she rebuilt her health from scratch in her 40s. And James Pieratt closes with a deep dive into what Spartan warriors actually trained like, and why it still holds up as one of the most complete blueprints for human performance ever devised.

Whether you listen start to finish or jump to the section that speaks to you most, you'll find something in here that changes the way you think about your health.

The Dirty Truth About Your UNDERWEAR, Cooking Oil & Chair? Microplastics, Hormones, Seed Oils, HRV & More: Best Of Roots Of Health

Full Show Notes: https://bengreenfieldlife.com/sisson2026 

In this episode with Mark Sisson, you'll discover why VO2 Max may be overrated as the gold standard for longevity, and why chasing it cost Mark 32 pounds of muscle and the real-world function that actually matters. You'll explore his "Old Man Olympics" framework: a decathlete's approach to fitness at 72, spanning strength, speed, balance, and endurance. You'll also get his take on cold plunging, alcohol, biohacking, AI, and find out why foot health may be the single most overlooked lever in your longevity toolkit, from bunions to glute activation to big toe function.

Mark Sisson ignited the ancestral health movement with Mark's Daily Apple and The Primal Blueprint, popularized keto and intermittent fasting with The Keto Reset Diet and Two Meals a Day, and sold Primal Kitchen to Kraft Heinz for $200M. He now runs Peluva, a toe-separated shoe company built around restoring foot strength and healthy gait, and is the author of Born to Walk.

Is VO2 Max "Overrated"? (& What To Focus On Instead), Old Man Olympics, Big Toe Health & More With Mark Sisson

Full Show Notes: https://bengreenfieldlife.com/emfguypodcast 

In this fascinating episode, Nick Pineault, also known as “The EMF Guy,” breaks down the latest science on radiofrequency radiation, including findings from the National Toxicology Program, the WHO classification of EMFs, and emerging evidence linking device exposure to oxidative stress and reduced sperm health. The conversation also highlights why current safety standards may not reflect real-world, long-term exposure.

You’ll also discover the concept of “body burden,” which is the accumulation of heavy metals, mycotoxins, and environmental toxins that can build up silently over time. Nick shares his own experience discovering high levels of lead, mercury, and mold toxins despite being physically fit, along with the changes he noticed after addressing detoxification through sauna therapy, oxygen cycling, and chelation. 

If you’re dealing with brain fog, low energy, or unexplained symptoms, this episode connects the dots between modern environmental exposures, from EMFs to microplastics, and how they may be influencing your overall health.

Nick Pineault is an investigative health advocate, author, and educator. He is the author of The Non-Tinfoil Guideto EMFsand has spent over a decade researching the health effects of electromagnetic fields and modern environmental exposures. His work focuses on translating complex scientific data into practical strategies for reducing risk in a technology-driven world.

He is also the creator of the documentary Body Burden, which explores the hidden accumulation of toxins in the human body and the emerging field of environmental medicine.
