How You’re Damaging Your Nerves And What You Can Do About It.

Full show notes: bengreenfieldlife.com/505

In this solosode, you'll get the latest on microplastics, spinal disc health, and what a heart scan sees that a cholesterol panel misses. A new seven-day trial pitted five plastic-avoidance strategies against each other, and the results tell you exactly where to spend your effort if you can't overhaul everything at once. You'll hear which plastic sources matter most and what I now take before bed with BrocElite® (use code BEN for 25% off your first month) to help clear microplastics from tissue. Then I get personal about my back. I'll walk you through my full-body MRI results, which show significant degeneration from L1 to S1, and explain why I still have almost zero back pain, from Dr. Stuart McGill's Big 3 to inversion hanging, the couch stretch, the founder stretch from Foundation Training, and my WALKOLUTION® treadmill desk ($100 off, enter your email for a unique code). You'll also learn why running was the only activity linked to healthier spinal discs in a study of more than 4,000 people, and why none of the sports people assume are hard on your back showed harm. Finally, you'll hear what a coronary CT angiography measures that your cholesterol panel cannot, why a 6,061-person study found plaque volume beats any standard risk calculator, what my own scan revealed, and the surprisingly simple thing that appears highly protective even when your plaque is already elevated.

The BIGGEST Step You Can Take To Reduce Microplastics, How To Get Rid of Back Pain, What You Need To Know About Heart Scans & More - Solosode #505

Full show notes: https://bengreenfieldlife.com/holyhealth

In this episode with Justin Roethlingshoefer, you'll hear from a former NHL performance coach turned health entrepreneur whose new book,Holy Health, is the one I chose for my father-son book club this month. This is not another eat-honey-and-drink-milk Bible health book. Justin is a genuine biohacker who works with pro athletes worldwide, and he has woven deep spiritual and physiological science into the same framework.

You'll learn why the modern obsession with optimization can quietly become idolatry, how the drive to control your metrics keeps your nervous system stuck in fight-or-flight and lowers your HRV, and the five "hearts" that trap high performers in striving. You'll also get the practical side: his full morning and evening rhythms, why he starts his day at 6 p.m. rather than at sunrise, the breathwork he does midday in the grass, his exact zone two and zone five weekly targets, and how he folds three and a half hours of zone two into family walks with a weighted vest. It's a conversation about doing less frantic optimizing and more intentional stewardship, and it may reframe how you think about every biohack you own.

The Myth Of The Perfect Health Routine: How To Raise Your HRV By Giving Up Control, With Justin Roethlingshoefer

Full show notes: https://bengreenfieldlife.com/504

In this solosode, you'll get the latest research on three questions I keep getting asked. First, seed oils: a brand-new randomized controlled trial put 52 adults on either a low or a typical Western intake of linoleic acid for 12 weeks, and the results are important less for what they found than for what they didn't. You'll hear why arachidonic acid didn't move, why EPA dropped instead, what that does to your inflammatory balance, which seed oils I still think are worth avoiding, and the one dietary adjustment that matters most if seed oils are part of your diet.

You'll also learn the surprisingly small amount of strength training that delivers the biggest longevity payoff, according to a 30-year study of more than 147,000 people, plus why pairing it with cardio is the single best exercise combination for blood pressure. I break down concurrent training, the interference effect between AMPK and mTOR, and when combining strength and cardio in one session helps you versus when it holds you back. Finally, I answer a listener question on peptides with six practical rules for stacking them safely, including which ones should never share a syringe, which ones cancel each other out at the receptor, and an honest look at how thin the human evidence really is behind the popular Wolverine stack.
