In this episode of The Human Upgrade, Host Dave Asprey reveals the surprising truth about broccoli—why adult broccoli can block thyroid function and irritate the gut, while broccoli seeds deliver sulforaphane, the powerful compound that activates all three of your body’s detox pathways. Joined by two Johns Hopkins–trained researchers in biochemistry and functional medicine, Dave uncovers how sulforaphane protects against glyphosate, repairs leaky gut, boosts mitochondria, and enhances metabolism, neuroplasticity, and brain optimization. You’ll learn how sulforaphane, berberine, curcumin, and alpha-lipoic acid can rival GLP-1 weight loss drugs, improve dopamine balance, and deliver smarter not harder biohacks for human performance, longevity, and resilience.
Most people think broccoli is a superfood, but the reality is more nuanced. In this episode of The Human Upgrade, Host Dave Asprey explores the good and bad of broccoli—why adult broccoli can block thyroid function and cause gut issues, while broccoli seeds deliver sulforaphane, the powerful compound that activates all three of your body’s detox pathways. You’ll learn how sulforaphane protects against glyphosate, repairs leaky gut, and upgrades mitochondria, metabolism, and longevity.
Dave is joined by two Johns Hopkins–trained researchers whose expertise in biohacking, biochemistry, and functional medicine makes them trusted leaders in the field. Together they reveal how sulforaphane, berberine, curcumin, and alpha-lipoic acid outperform bulk vegetables and even rival GLP-1 weight loss drugs—delivering natural ways to improve metabolism, regulate dopamine, and protect the brain. Their research shows how targeted supplements can boost neuroplasticity, brain optimization, and human performance without the side effects of pharmaceuticals.
Dave and his guests break down why bulk vegetables don’t deliver enough beneficial compounds, how to hack plant toxins for maximum benefit, and why supplement stacks often outperform carnivore, vegan, or high-vegetable diets for long-term health. You’ll discover how biohacking tools like fasting, ketosis, nootropics, cold therapy, and sleep optimization amplify these compounds for smarter not harder living.

00:00 — Trailer
A fast-paced highlight reel sets up the episode’s focus on broccoli compounds, detox, and weight loss.
01:10 — Introduction
Dave welcomes Johns Hopkins biochemists back to discuss detox pathways, AI-assisted research, and new findings.
01:49 — Broccoli Benefits & Risks
Exploring the differences between mature broccoli and sprouts, including thyroid blockers, DIM, I3C, and sulforaphane.
09:24 — Plant Toxins & Modern Diet
Why plants contain both beneficial compounds and toxins, and how biohacking isolates what works without the downsides.
12:56 — Mold Detox Experiences
Dave shares his mold exposure history and explains how sulforaphane and glutathione help him recover during travel.
18:30 — Mycotoxins, Glyphosate & Gut Health
The team explains how mold toxins and glyphosate disrupt tight junctions in the gut, and how sulforaphane repairs the damage.
