Modern Diet, Tryptophan, and Brain Chemistry

Most people try to “heal” their brain with supplements, mindset, or meditation—but this episode reveals the deeper protocol to actually grow a new brain, reverse stress damage, activate 1,100 healing genes, and unlock higher human performance at any age. You’ll learn how neuroplasticity, mitochondria repair, plant-based NRF2 activators, and energetic practices work together to rebuild the brain and extend longevity.

Host Dave Asprey sits down with Alberto Villoldo, Ph.D.—medical anthropologist, neuroscientist, energy medicine pioneer, and founder of The Four Winds Society, the gold-standard school for modern shamans. He has spent 25+ years studying Amazonian and Andean healing traditions, led the Biological Self-Regulation Lab at San Francisco State University to explore psychosomatic medicine, and authored more than 25 bestselling books on neuroscience, functional medicine, and energy healing. Few people on earth bridge ancient biohacking and modern brain science at this level. 

He also reveals the forms of nicotine that are safest (spoiler: it’s not vapes or cigarettes), how nicotine works at the receptor level, and what the science says about long-term health effects. This episode blends functional medicine, brain optimization, and biohacking into one powerful, myth-busting breakdown. 

You'll learn: 

• How to grow a new brain every 22 days using neuroplasticity and mitochondria support 

• Why plant medicines and NRF2 activators can turn on 1,100 healing genes in 24 hours 

• The surprising link between nootropics, psychedelics, serotonin, and endogenous DMT 

• How mindset, belief systems, and placebo/nocebo shape immune function and metabolism 

• Why RFK’s chronic disease warning connects to viral evolution and immune collapse 

• The real reason carnivore diets work—and when they fail without gut repair 

• Peptides, GLP-1 agonists, and the future of functional medicine hacking 

• Why most people sabotage themselves and how to stop fighting your own biology 

This is essential listening for anyone serious about biohacking, human performance, and longevity, and for those who want to understand how functional biology and mitochondrial science are redefining recovery, energy, and aging.
