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. 

You’ll Learn: 

• Why adult broccoli can disrupt thyroid function while broccoli seeds fuel detox and longevity 

• How sulforaphane, berberine, curcumin, and alpha-lipoic acid support metabolism and mitochondria 

• Why natural compounds can rival GLP-1 drugs for weight loss and energy regulation 

• The connection between glyphosate, leaky gut, inflammation, and brain fog 

• How to stack supplements with fasting, ketosis, and cold therapy for brain optimization 

• Why functional medicine and biohacking provide better long-term solutions than fad diets 

• The smarter not harder way to extract benefits from plants without the toxic load 

This episode is essential for anyone serious about biohacking, upgrading metabolism, extending longevity, and achieving high performance with resilience and clarity.
