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

Full Show Notes: 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.
