    Episode Overview

    In this episode of the Prescribed Podcast, Dr. Nathan Goodyear sits down with regenerative farmer Gail Fuller, founder of Fuller Farms and Fuller Field School in Kansas, to uncover the direct connection between soil health, human health, and rising chronic disease. Gail shares his powerful story of walking away from chemical-dependent, industrial farming—even when it cost him his community and his family’s multigenerational farm—to rebuild a regenerative, diverse, nutrient-dense operation focused on life, not death. Together, he and Dr. Goodyear expose how degraded soil leads to weakened immunity, disrupted gut microbiomes, and increased cancer risk—and how true healing begins with rebuilding the land. This isn’t just a conversation—it’s a call to action to partner with farmers, rebuild local food systems, and rethink prescriptions as pathways to real, lasting health.

    📌 Key Takeaways Farmers are the original doctors of the soil. Soil health determines food quality, immune strength, and disease vulnerability—including cancer. Industrial agriculture disconnects us from food. The shift from “food” to “commodities” made toxic farming practices seem normal and erased the link between land and health. Glyphosate acts like an antibiotic. Its widespread use harms soil life and the gut microbiome—key foundations for immunity and long-term wellness. Cancer is a warning signal. Dr. Goodyear reframes cancer as the “canary in the coal mine,” a sign of broader environmental and biological collapse. Regenerative farming restores life. Gail’s shift from 3,200 chemical-heavy acres to a diversified, regenerative 160-acre farm shows soil can heal—and so can people. The cost of change is real. Gail lost his crop insurance, financial support, and community acceptance when he rejected chemical farming, yet rebuilding saved his health. Doctors can prescribe food, not just pharmaceuticals. Imagine prescriptions directing patients to farmers instead of pharmacies—fueling health rather than disease. Local food systems rebuild communities. Connecting consumers, doctors, and farmers supports rural revival, public health, and long-term resilience. Healing requires nature, not convenience. Moving away from instant gratification and toward intentional investment in real food is essential. The future of healthcare may look like a farm. True healing happens on living soil, in clean air, in natural rhythms—not under fluorescent hospital lights.

  • Your Food Isn’t What It Used To Be—Here’s Why
    Nov 7 2025
    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/ Episode Overview In this powerful conversation, Dr. Nathan Goodyear sits down with Dr. Don M. Huber, Professor Emeritus of Plant Pathology at Purdue University and a pioneering voice on soil health, glyphosate, and agro-ecology. Drawing on five decades of research, Dr. Huber explains how glyphosate functions as both a chelator and an antibiotic, how that impacts nutrient density, plant disease, animal health, and human outcomes—and what practical steps farmers, clinicians, and families can take right now. From re-emerging crop diseases to miscarriages and mitochondrial stress, this episode connects the dots from soil to cell—and offers real-world remediation strategies (including microbial approaches) to help regenerate land and protect health. This isn’t just a conversation—it’s a call to action. 📌 Key Takeaways Glyphosate is a potent mineral chelator. By binding manganese, zinc, iron, and other cations, it reduces plant nutrient uptake and can lower nutrient density across the food chain. Antibiotic effects alter the microbiome. Glyphosate can suppress beneficial microbes and favor pathogens in soil, animals, and potentially the food system, shifting ecological balance. Re-emerging plant diseases are rising. Decades-long field observations link glyphosate exposure with increased severity of fungal and soil-borne diseases in major crops. Nutrient density has declined. Multi-decade comparisons show lower micronutrients in harvests; Dr. Huber outlines mechanisms and field examples (e.g., pumpkins following Roundup Ready corn). Small amounts can matter. Field rates discussed suggest even fractional ounces per acre may impair metal transport—context clinicians should consider when evaluating diet-based deficiencies. Ecology ↔ human health link. The episode explores epidemiologic patterns (e.g., cancer, celiac, autism curves) discussed alongside exposure trends—framed as signals to investigate, not final proofs. Animal health case studies. Dairy and livestock examples (e.g., chronic botulism patterns) illustrate how feed residues and microbiome disruption may impact performance and loss rates. Environmental spillovers. Runoff and waterway eutrophication, algal blooms, and filtration bypass are covered as downstream consequences of broad herbicide use. Regulatory blind spots. The conversation critiques active-ingredient–only assessments and calls for fuller evaluation of adjuvants and formulations. Microbial remediation is promising. Field trials with Lactobacillus (e.g., raw sauerkraut juice/L. plantarum consortia) showed notable reductions in residual glyphosate and yield rebounds. Action steps for clinicians and patients. Prioritize nutrient-dense foods, soil-forward sourcing, and mitigation strategies while advocating for transparent oversight. Heal the land to heal patients. Prevention in oncology begins upstream—support regenerative agriculture as a public-health intervention. ⏱️ Timestamps 0:00 – Episode intro & mission 1:03 – Why healing soil matters for preventing cancer 1:43 – Dr. Don M.

  • Rejecting Chemo for Alternative Healing: A Stage 3 Cancer Thriver’s Journey | Chris Joseph
    Oct 30 2025

    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/

    Episode Overview

    At Metabolic Health Day in Tucson, Dr. Nathan Goodyear sits down with Chris Joseph—cancer thriver, author of Life Is a Ride: My Unconventional Journey of Cancer Recovery, and Certified Radical Remission Coach—for a raw, practical roadmap from stage III pancreatic cancer to long-term NED. Chris unpacks how taking the driver’s seat (“be the CEO of your health”), leveraging integrative tools, and building a support team shifted his trajectory when conventional chemo failed. From mistletoe and hyperthermia to mindset, movement, and food, this episode connects real-world choices to outcomes—and pushes clinicians and patients to collaborate better. This isn’t just a conversation—it’s a call to action.

    📌 Key Takeaways

    Be the CEO of your health. Patient-led decision-making changes options, adherence, and outcomes—especially when fear and fatigue dominate early cancer care.

    Chemo isn’t the only lever. When treatment failed and side effects escalated, Chris pivoted to integrative strategies without abandoning science or results.

    Hope is a clinical variable. Restoring agency and purpose improves resilience, decisions, and follow-through across a long journey.

    Metabolic & immune targeting matter. Tools like IV vitamin C, mistletoe, hyperthermia, and low-carb nutrition can support immune function and therapy synergy.

    No magic bullet—stack wins. Progress came from combinations (therapies + lifestyle + mindset), not a single intervention.

    Mindset and support are treatment. Community, coaching, and family support stabilized emotions and sustained behavior change.

    Data-informed, person-specific. What’s “right” depends on the individual—timing, tolerance, comorbidities, logistics, and goals.

    Reframe statistics. Population odds inform risk; individual choices shape the path forward.

    Movement is medicine. Simple, consistent walking delivered zero-cost, high-upside benefits for energy, mood, and metabolism.

    Collaboration over silos. Advocates, physicians, and patients working together reduce confusion and accelerate safer, smarter care.

  • Cancer Stem Cells Aren’t “Roots”: The Plasticity Model Explained
    Sep 26 2025
    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/ Episode Overview: Cancer stem cells (CSCs) aren’t “fixed roots” you can yank out—they’re shape-shifters. In this solo deep dive, Dr. Nathan Goodyear, MD, MDH, ABAARM, breaks down the pivot from the old rigid tumor hierarchy model to today’s plasticity paradigm, showing how CSCs dynamically reprogram in response to microenvironmental cues and treatment pressure. He maps the evidence timeline (1997 → 2025), explains why the “magic bullet” fails, and outlines multi-axis strategies that target both CSC identities and the reprogramming circuits that let tumors adapt. This isn’t just a conversation—it’s a call to action. 📌 Key Takeaways From fixed to flexible: The field has shifted from a rare, static CSC “root” to dynamic, reprogrammable states across a spectrum. Microenvironment matters: Hypoxia, acidity, immune cells, cytokines (e.g., TGF-β, IL-6) and stromal players drive CSC plasticity; target the neighborhood, not just the “seed.” Therapy pressure reshapes tumors: Surgery, chemo, radiation can unintentionally induce CSC traits, fueling resistance, recurrence, and metastasis. Epigenetic—not just genetic: Rapid phenotypic switching is powered by epigenetic rewiring (transcriptomic/proteomic/metabolic shifts), not necessarily mutations. Parallels across immunity: Macrophages (M1/M2), neutrophils (N1/N2), T cell effector↔regulatory toggling mirror CSC plasticity—biology favors state transitions. EMT ↔ MET as a lever: Epithelial–mesenchymal transitions promote motility, stemness, and therapy escape; reverse transitions enable colonization. Markers aren’t destiny: CSC markers (CD133, CD44, ALDH activity) are heterogeneous and context-dependent; no single marker defines CSCs across cancers. Why “target the root” fails: Eliminate one pool (e.g., LGR5⁺) and redundant or oncofetal programs compensate; blocking reprogramming is essential. Clinical framing: Reimagine cancer as an adaptive ecosystem; use combination/stacked strategies (standard of care + plasticity inhibitors / microenvironmental mods). Actionable shift: Build protocols that measure and modulate inflammation and immune signaling while avoiding one-size-fits-all dosing (precision IV vitamin C is one example of dosing by PK/PD realities). ⏱️ Timestamps 00:00:37 – Cancer stem cells: setting the stage 00:02:12 – CSCs as shape-shifters: plasticity over hierarchy 00:04:08 – Evidence timeline (1997→2025): from hierarchy to plasticity 00:08:03 – The fixed hierarchy model (roots & branches) 00:09:35 – Tumor microenvironment & therapy pressures 00:10:29 – Epigenetic reprogramming & real-time phenotypic switching 00:12:16 – Bidirectional state shifts (CSC ↔ non-CSC; EMT/MET) 00:14:16 – Immune cell plasticity parallels (M1/M2, N1/N2) 00:16:36 – T-cell plasticity: effector ↔ regulatory toggling 00:20:47 – Therapeutic implications: fixed vs plasticity-informed strategies 00:24:34 – CSC markers & caveats (CD133, CD44, ALDH; heterogeneity) 00:27:42 – Beyond the magic bullet: cancer as adaptive ecosystem 00:36:59 – How surgery/chemo/radiation induce CSC traits 00:43:05 – New consensus & multi-axis treatment playbook 🔔 Subscribe for more evidence-based conversations on the future of functional medicine. 📚 Resources & Links: Chosen research thread (ResearchRabbit collection): https://www.researchrabbitapp.com/collection/public/0LJGWQ9PLW Key citations (APA): Dvorak, H.

  • Cancer Stem Cells: From Fixed Roots to Shape-Shifters
    Sep 18 2025

    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/ Episode Overview In this episode of the Prescribed Podcast, Dr. Nathan Goodyear takes us inside a groundbreaking shift in cancer biology: the move from the old fixed hierarchy model of cancer stem cells (CSCs) to the dynamic plasticity paradigm. Rather than being static “roots” that can simply be cut away, CSCs are revealed as shape-shifters—reprogramming, adapting, and outmaneuvering therapy under environmental and therapeutic pressures. Dr. Goodyear connects the dots between stemness, immune cell plasticity, tumor microenvironments, and treatment resistance, challenging the outdated “magic bullet” paradigm. This isn’t just a conversation—it’s a call to action for rethinking how we design therapies to target cancer’s adaptability at its core. 📌 Key Takeaways Cancer stem cells aren’t fixed roots. They exist on a spectrum of states, able to pivot between stem and non-stem activity. Plasticity defines modern cancer biology. CSCs dynamically adapt their phenotype in response to stressors, environment, and therapies. The classical CSC hierarchy is outdated. The “root-and-branch” model no longer explains tumor complexity. Environmental cues drive stemness. Hypoxia, cytokine signaling, and microenvironment interactions induce stem-like traits. Therapeutic pressure fuels resistance. Surgery, chemo, and radiation trigger CSC reprogramming, enabling relapse and metastasis. Epigenetic reprogramming powers adaptability. CSCs switch phenotypes without changing their DNA code, making them harder to eliminate. CSC plasticity mirrors immune cell behavior. Macrophages, neutrophils, and T cells show similar polarization and state-switching. The magic bullet paradigm is broken. Single-target therapies can’t stop a moving, adaptive cellular ecosystem. Clinical implication: treat the plasticity. Success requires multi-axis therapies that block reprogramming pathways and tumor adaptation. 90% of cancer mortality comes from metastasis. Understanding CSC plasticity is essential for tackling recurrence and spread. ⏱️ Timestamps 0:00 - Episode Intro 0:35 - Cancer stem cells as shape-shifters 1:20 - Old hierarchy model vs. new plasticity model 2:15 - Why targeting CSCs in isolation fails 3:17 - The “root” theory of CSCs explained 4:15 - Tumor heterogeneity and microenvironment dynamics 5:15 - Senescent cells and immune system hijacking 6:12 - The shift from hierarchy to adaptability 7:15 - Therapeutic pressures driving CSC plasticity 8:11 - Epigenetic reprogramming and phenotype switching 9:00 - Immune cell plasticity parallels: macrophages, neutrophils, T cells 10:00 - EMT/MET and metastasis explained 11:00 - Why the magic bullet paradigm fails in cancer 12:12 - New consensus: CSC plasticity as the frontier of cancer biology 13:45 - Call to action and show notes 🔔 Subscribe for more evidence-based conversations on the future of functional medicine. 📚 Resources & Links Mzoughi, S., Heuberger, J., Schaefer, S.

  • Is Less More? The Science of Low-Dose Chemo & Quality of Life in Cancer Care
    Sep 5 2025

    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/

    Episode Overview

    In this solo episode, Dr. Nathan Goodyear breaks down the science and strategy of Low-Dose Metronomic Chemotherapy (LDM)—and why shifting from maximum-tolerated “warfare” to immune-supportive, precision dosing can change outcomes and quality of life. He distinguishes LDM, fractionated dosing, and ultra-low-dose “immunogenic chemotherapy,” then connects the dots from tumor angiogenesis and the tumor microenvironment to chemo-immunomodulation that turns cold tumors hot. This isn’t just a conversation—it’s a call to action: rethink dosing, protect the immune system, and personalize combination therapy.

    📌 Key Takeaways

    LDM focuses on biology, not brutality. Lower doses given more frequently can maintain antitumor pressure while sparing healthy tissue and immunity.

    Typical LDM ranges ~10–30% of MTD. Above ~50% is not “low-dose” and risks cumulative toxicity similar to full-dose regimens.

    Two core mechanisms drive LDM benefits. Anti-angiogenesis reduces tumor blood-supply growth, and immunomodulation enhances antitumor immunity.

    Ultra-low-dose can be immunogenic. Carefully titrated chemo can trigger immunogenic cell death, DAMP release, dendritic-cell activation, and CD8+ T-cell priming.

    Cold → hot tumor conversion is possible. LDM helps recruit cytotoxic T cells/NK cells and reduce Tregs/MDSCs to enable immune infiltration.

    Chemo sensitivity can be restored. LDM may re-sensitize previously resistant tumors and reduce cancer stem-cell populations.

    Quality of life improves with less toxicity. Evidence cited shows lower grade 3–4 adverse events and comparable disease control to conventional dosing.

    Biomarker to watch: NLR. Tracking the neutrophil-to-lymphocyte ratio can reflect immune status and therapy directionality.

    Microbiome matters. Prolonged/high-dose chemo can damage gut barriers and metabolites; LDM aims to treat without “scorched-earth” effects.

    Best used in combos. LDM pairs with intratumoral therapies, immunotherapy, targeted agents, radiation, metabolic care, and more—by design, not by default.

  • Can Injecting Tumors Train the Immune System to Beat Cancer | Cancer Geeks
    Aug 29 2025

    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/

    Episode Overview

    What if you could inject a tumor and ignite the immune system—not just locally, but systemically? In this episode of the Prescribed Podcast, Dr. Nathan Goodyear sits down with Dr. Jason Williams, founder of the Williams Cancer Institute and pioneer of intratumoral immunotherapy. Together, they unpack a landmark 2025 study on Fc-optimized CD40 agonists and explore how direct injection into tumors is transforming cancer treatment. From tertiary lymphoid structures to pulsed electric fields (PEFs), this isn’t just a conversation—it’s a call to action for patients, clinicians, and researchers ready to revolutionize cancer care.

    📌 Key Takeaways CD40 is the Swiss Army knife of immunotherapy. It primes T cells, activates dendritic cells, reprograms macrophages, and supports B-cell immunity.

    Systemic CD40 delivery is toxic. Intravenous administration causes cytokine storms, liver injury, and platelet loss.

    Intratumoral injection avoids toxicity. Local delivery reprograms the tumor microenvironment while still driving systemic immune responses.

    Phase I trial showed promise. Among 12 patients, 20% had complete responses and 60% achieved stable disease—without dose-limiting toxicities.

    Abscopal effect observed. Injected tumors triggered regression in non-injected lesions.

    TLS are immune training camps. These tertiary lymphoid structures enable long-term immune memory and stronger systemic antitumor activity.

    PEF boosts immunity. Pulsed electric fields induce tumor death, enhance antigen release, and synergize with CD40.

    Combination is key. Checkpoint inhibitors, chemo-radiation, and ablation therapies amplify intratumoral CD40’s effects.

    Adaptive precision matters. Not all patients respond the same; tailored multi-agent regimens outperform single drugs.

    Williams Cancer Institute leads innovation. Dr. Williams is already applying these strategies in clinical practice today.

    📬 Join Dr. Goodyear’s Newsletter ➡️ https://pre-scribed.com/subscribe/ 🎙️ Episode Overview: In this powerful solo episode of the Prescribed Podcast, Dr. Nathan Goodyear confronts the emerging debate within the natural and integrative medicine world: Is it time to move beyond ivermectin in cancer care—and does artemisinin offer a better solution? Drawing on decades of clinical experience, a robust survey of mechanistic studies, and his signature emphasis on evidence-based medicine, Dr. Goodyear compares the anticancer potential of ivermectin and artemisinin/artesunate. He dismantles faulty generalizations, calls out censorship in research, and builds a compelling case for why integrative oncology must transcend “zero-sum” thinking. This isn’t just a conversation—it’s a call to action for clinicians, patients, and health leaders to follow the science, not the narrative. 📌 Key Takeaways: Both ivermectin and artemisinin are Nobel Prize-winning anti-parasitics but diverge significantly in anticancer mechanisms.

    Artemisinin’s anticancer impact relies on iron-dependent activation, triggering ferroptosis, apoptosis, and immune modulation.

    Artesunate (semi-synthetic derivative of artemisinin) is clinically superior due to its water solubility, IV accessibility, and bioavailability.

    Ivermectin inhibits Wnt/β-catenin, EMT, mitochondrial respiration, and modulates cold tumors to hot—reprogramming immune accessibility.

    Artemisinin targets angiogenesis, STAT3, HIF-1α, and tumor-associated macrophages, shifting M2 (pro-tumor) to M1 (anti-tumor).

    Head-to-head comparisons between the two agents don’t exist, but both may work synergistically due to complementary mechanisms.

    Ivermectin shows broader preclinical reach, while artemisinin and artesunate have stronger emerging clinical signals.

    Research on ivermectin in cancer is being suppressed, whereas artemisinin continues to gain traction and legitimacy.

    Integrative oncology isn’t “either/or”—it bridges the best of natural and conventional therapies with precision and intention.

    Zero-sum thinking is the enemy of progress. Healing demands nuance, science, and holistic synthesis—not dogma.

    Pharmacokinetics matter. Route of administration, absorption, and conversion (e.g. to dihydroartemisinin) directly impact therapeutic efficacy.

    Ivermectin and artesunate are tools—not magic bullets. They must be used in patient-specific, strategically timed combinations.
