Episode 257: Dr. Nasha Winters, ND, FABNO - Cancer, UPFs, and Metabolic Healing

In this episode, we sit down with integrative oncologist and metabolic health pioneer Dr. Nasha Winters (who insists we call her Nasha) to explore the powerful intersection of cancer, ultra-processed foods, metabolism, and sovereignty.

Nasha shares her astonishing personal story: years of dismissed symptoms, normalized suffering, and relentless gaslighting that culminated in a diagnosis of end-stage ovarian cancer at age 19—and being sent home to die. Thirty-four years later, she’s very much alive and leading a global movement to rethink cancer as a metabolic, terrain-driven disease rather than a purely genetic accident.

We talk about how ultra-processed foods don’t just starve our mitochondria—they starve our sovereignty, hijack our decision-making, and fracture our relationship with our own bodies.

Along the way, Nasha invites us to move away from perfectionism and fragility and toward aligned, values-based choices and fierce self-responsibility.

In this episode, we explore:

• Nasha’s “pain to purpose” story

  • Chronic health issues from infancy through adolescence: PCOS, endometriosis, autoimmune issues, RA, IBS, thyroid dysfunction, and more—constantly normalized and medicated.

  • Being diagnosed with end-stage ovarian cancer at 19, with full bowel obstruction, organ failure, metastasis, and “3 months to live.”

  • How being sent home to die became the catalyst for asking “Why?” and beginning her life’s work.

• A metabolic and psychological reset

  • Why a prolonged period of fasting (due to bowel obstruction) functioned as an unplanned metabolic intervention.

  • How an accidental very high-dose psilocybin experience in 1991 fundamentally changed her perspective, reduced her fear of death, and gave her a will to live.

  • The insight that cancer is not just genetic—but deeply tied to environment, metabolism, trauma, and disconnection from nature.

• Cancer as an ecosystem, not a battlefield

  • What Nasha means by seeing the body as an ecosystem instead of a war zone.

  • How we are in constant relationship with our internal and external environments—our bodies, food systems, and the land all reflecting each other.

• Ultra-processed foods and cancer terrain

  • Why ultra-processed foods are “as genetically mismatched as it gets” for humans.

  • How UPFs impact all the hallmarks of cancer—driving inflammation, insulin resistance, oxidative stress, mitochondrial dysfunction, and brain hijacking.

  • The role of emulsifiers, preservatives, seed oils, and other additives in damaging the gut, microbiome, and immune surveillance.

  • Why “a little” ultra-processed food isn’t neutral for people with a vulnerable system—and why in her oncology population, UPF often has to be all-or-nothing.

• Metabolic sovereignty vs. perfectionism

  • Nasha’s powerful idea that UPFs don’t just starve our mitochondria—they starve our sovereignty.

  • What it means to choose health as alignment, not achievement.

  • How social pressure, cultural norms, and “moderation” language rob people of agency.

  • Practical examples of reclaiming sovereignty: bringing your own wine, your own safe foods, and modeling a different way without preaching.

• Working with food addiction and emotional eating (without shame)

  • How she meets people gently where they are, especially those whose only “comfort” has been food.

  • “Upgrading” comfort foods and using cooking and eating as a creative, relational, and communal act rather than a shame-based one.

  • Her boundary as a clinician: “I’m not willing to work harder than you.” How that shifted outcomes and reduced codependency.

• Community, clinicians, and doing this together

  • How she used farmers’ markets and health-food store “field trips” as non-shaming education: reading labels together, swapping recipes, and making it fun.

  • Seasonal group cleanses and experiments that removed UPFs without moralizing and re-connected people to real food.

• Justice, food deserts, and real solutions

  • Stories from working in Indigenous and low-resource communities and helping reintroduce native seeds and traditional foodways.

  • The Food-as-Medicine movement: projects like FreshRx, where CSA boxes for people with type 2 diabetes significantly lowered A1C and healthcare costs.

  • Why she believes, increasingly, that the resources are there—and the work now is connection, awareness, and community organizing.

• A hopeful vision for the next 5 years

  • Policy shifts around dietary guidelines and school food.

  • Regenerative agriculture movements, farmer-led organizations, and bringing environmental, metabolic, mental health, and food systems together under one roof.

  • Her dream project: a 1,200-acre regenerative farm, intentional community, and metabolic oncology hospital in Arizona.

• One small step you can take this week

  • Start with non-judgmental awareness: a simple food and feeling diary.

  • Her “triage” before reaching for UPFs:

    1. Big glass of water

    2. A bit of protein

    3. A bit of fat

    4. Then the UPF if you still truly want it—no self-punishment.

  • How small wins (“I didn’t eat the thing”) build fierceness and confidence over time.

• Our signature question

  • What Nasha would tell her younger self about ultra-processed foods:

    “I’m choosing health as alignment, not as achievement.”
    Using food choices to align with who you really are and who you’re becoming, rather than chasing perfection or performance.
