“Thinking is the language of the mind. Feeling is the language of the body. When the body’s inflamed, when the body’s stressed, when the body has a lot of, you know, toxicity in it, we don’t really want to feel the body. It’s uncomfortable. So a lot of times the mind becomes overactive as a way of numbing out feelings in the body, almost like since the body’s really uncomfortable, we start to live from the neck up to avoid feeling what’s happening below,” says Greg Schmaus, holistic health practitioner and founder at Healing For Zero, on Mental Health in a Modern World.
A survivor of severe anxiety and OCD, Greg Schmaus has spent a decade guiding others through integrative healing—bridging nutrition, biology, psychology, and spiritual practice. In this episode, he dismantles the reductionist mindset of modern medicine, which treats mental health as a mere chemical equation, and instead invites us to consider ourselves as living ecosystems—trillions of cells, bacteria, thought patterns, relationships, and boundaries all constantly interacting.
Greg Schmaus explains why gut health is foundational to mental and emotional wellbeing, and reveals how everything from antibiotics, processed foods, chronic stress, or environmental toxins can disrupt the delicate dance between our “abdominal brain” and our mind. He explores the two-way highway connecting gut and brain, the dangers of dysbiosis and leaky gut, and powerful, actionable approaches for tending your ‘inner garden’: from diverse, whole-food eating to gratitude, sleep, circadian rhythm support, and breathwork.
Learn how caring for your microbiome may be the missing piece in calming anxious minds, restoring self-identity, and reclaiming true health—and why tending to both your inner and outer gardens is the path forward—for body, mind, and planet.
5 Key Takeaways
To transform your mental and gut health, start making these changes today:
1. Feed your microbiome by eating a diverse diet rich in whole foods, fibers, prebiotics, and fermented foods as tolerated.
2. Protect your gut by reducing processed foods, excess sugar, unnecessary antibiotics, alcohol, and exposure to chemicals and pesticides.
3. Support your nervous system—prioritize quality sleep, manage stress, and incorporate practices like meditation, breathwork, tai chi, or qigong.
4. Spend more time in nature to nourish your inner and outer ecosystems, reinforcing your connection with the natural world.
5. Foster social connection and gratitude, and practice simple activities like gargling, humming, and abdominal massage to strengthen your vagus nerve and boost gut-brain health.

Memorable Quotes
"Thinking is the language of the mind. Feeling is the language of the body."
"The gut is our biological interface; it’s the boundary that differentiates what’s you from what’s not you on a cellular level, the outside world and your inner biological environment."
"Supporting the health of the body and the mind is more of an art than a science. When we learn how to garden well and balance the terrain, that’s when we really optimize health."
