Ironman 70.3 Japan Pre-Race Interview

Full show notes: bengreenfieldlife.com/braindefenders

In this episode, board-certified neurologist Dr. David Perlmutter joins me to talk through his new book, Brain Defenders, and his case that the beta-amyloid drugs for Alzheimer’s (drugs that target a sticky brain protein) haven’t delivered the results many hoped for. You’ll discover how microglia, your brain’s own immune cells, can protect your neurons or damage them, and what may tip them in either direction. You’ll also learn why the metabolism of those cells may mirror the metabolism of your whole body, which could put more of your brain’s future in your hands than you might expect.

David and I also dig into the gut-brain link, from ultra-processed food to fecal transplants, the blood tests he recommends, and how herbicides like glyphosate and paraquat, as well as wildfire smoke, may affect your brain. You’ll learn about duckweed, minocycline, and RNS60, a nanobubble saline being studied in stroke and amyotrophic lateral sclerosis (ALS), what the glucagon-like peptide-1 (GLP-1) trials in Parkinson’s and Alzheimer’s reported, my own accidental retatrutide injection, and the lifestyle trial that reported improvements in early Alzheimer’s after 20 weeks without using any drugs.

You can find his new book, Brain Defenders, here.

How To Turn Your Brain’s Immune Cells Into Alzheimer’s Defenders (& Why The Amyloid Drugs Fall Short), With Dr. David Perlmutter

Full show notes: bengreenfieldlife.com/behindthehuman

In this episode, I’m in the hot seat on Marc Champagne’s Behind the Human podcast, talking identity, legacy, and the story behind my documentary, Boundless: The Man Who Became Human. You’ll hear how tying my worth to achievement pulled me away from my family, the rites of passage I built for my sons, where the “Boundless” name came from, and how Caleb Applegate created a film that Zac Efron executive produced.

We also dig into questions from the AI-powered wisdom keepers in Marc’s new book, You’re Invited, including which practices I’d keep if none of them extended my life and what I finally stopped doing. You’ll learn why exercise beats piling on biohacks, how I stay true to my creative work, my daily, weekly, and annual reflection rituals, what excites me in the longevity space, and what my late father would be proudest of in how I’m raising my sons.

You can find his new book, You’re Invited, here.

Is Your Self-Worth Tied To Your Achievements? How To Aim Your Ambition At What Really Matters, With Marc Champagne

Full show notes: BenGreenfieldLife.com/jaspr3

In this episode, repeat guest Michael Feldstein, founder of Jaspr, joins me in my Idaho studio to make the case that synthetic fragrances are the new secondhand smoke. You’ll hear why the air freshener in your Uber may be doing more harm than you think, how fragrance dulls your sense of smell and even your digestion, and what Michael does to keep his air clean on the road when he can’t ship a Jaspr ahead of him.

We also dig into the research tying air quality to cognitive performance, from MLB umpires to chess players to the healthy buildings work of Harvard’s Dr. Joseph Allen, plus what Michael thinks about stacking nasal strips with clean air. You’ll learn how he built Kindling Academy in Austin to be the healthiest school in America, the humidity range that keeps mold and bacteria in check, how to upgrade your car’s cabin filter, and why gyms and dental offices have some of the worst air quality you’ll breathe. We close with an early Black Friday deal on the Jaspr Air Scrubber.
