What if the key to better health isn't another supplement, biohack, or medical breakthrough, but reconnecting with nature?
In this episode of Grounded Wellness, Bethany sits down with Dr. Zach Bush, a physician and former cancer researcher whose work led him from studying cancer cells and mitochondria to exploring the soil microbiome, regenerative agriculture, and the relationship between human health and the natural world.
Filmed outdoors on the Primally Pure regenerative farm, this conversation challenges the way we think about modern medicine, environmental toxins, and what it really means to be healthy.
Dr. Bush shares why he believes we've become disconnected from the very ecosystems that sustain us, how soil health and the human microbiome are interconnected, and why our increasingly sanitized, indoor lifestyles may be missing something fundamental.
They also explore the science of forest bathing, including how spending time among trees, seeing greenery, and experiencing the natural aromas of a forest may influence our nervous system and stress response.
From glyphosate and conventional farming to probiotics, multivitamins, and the booming biohacking industry, Dr. Bush offers a thought-provoking perspective on what happens when we try to replace nature rather than live in relationship with it.
Whether you're curious about gut health, environmental toxins, regenerative farming, forest bathing, or natural wellness, this conversation invites you to rethink what health really looks like.
