Eat well without the noise.

A free curriculum and a 1,600-entry glossary, distilled from twenty books on food, nutrition, and the industry that sells it. No diet talk, no fearmongering, no “clean eating.” Just what's actually known — and what to do about it.

How Food Actually Works

Twelve modules on what's actually happening when you eat. Mechanism first, recipes never.

  1. 01What is food, really?

    Food is something that was alive recently, transformed only by methods a home cook recognizes — everything else is an industrial formulation.

  2. 02Inside your cells: mitochondria, ATP, and insulin

    Mitochondria turn food into ATP; insulin tells cells where to store the rest; modern food breaks both, and that breakage is the upstream cause of most chronic disease.

  3. 03Macronutrients without the moralism

    Carbs, fats, and proteins are categories of fuel and building blocks — not moral categories. Quality and dietary pattern matter more than the macro ratio.

  4. 04Micronutrients & DRIs

    Vitamins and minerals are the catalytic chemistry your cells run on. The DRI framework (RDA, AI, EAR, UL, CDRR) sets population targets for adequacy, but the doses that prevent scurvy aren't the doses that optimize chronic-disease risk — and isolating nutrients into pills rarely reproduces what food does.

  5. 05Your microbiome and you

    Your gut microbiome is a community of roughly 100 trillion microbes that ferments fiber, makes vitamins, trains your immune system, and helps decide how every meal affects you. It's a nutritional organ — and most of the modern diet is starving or damaging it.

  6. 06Sugar — the clearest case

    Sugar is the single dietary input with the deepest evidence-based case against it: a distinctive fructose-driven liver biochemistry, a 50-year insulin-resistance cascade traced from cell to organ system, and a documented industry-capture history that delayed the science by four decades.

  7. 07Fats — the messiest story

    Fats spent fifty years as the villain of American nutrition. The science says the categories matter — saturated, mono, poly, trans — and what you replace a fat with matters more than the fat itself.

  8. 08The ultra-processed food problem

    Ultra-processed food is a precise category — defined by industrial ingredients, not nutrient profile — and the strongest single dietary lever on chronic disease.

  9. 09How food gets engineered

    Processed food is the output of a research-and-marketing pipeline that has refined the same eight techniques — bliss point, sensory-specific satiety, share of stomach, speed, layering, flavor industry, store engineering, and child marketing — for fifty years.

  10. 10Reading labels like an analyst

    A food label is a regulated marketing surface. The ingredient list tells you what is in the box; the Nutrition Facts panel tells you the lab math; everything on the front of the package is a sales pitch — including most of the seals.

  11. 11The additive playbook

    Most of the 10,000+ substances allowed in U.S. food are inert. About forty matter — and a regulatory loophole means roughly nobody is checking the rest.

  12. 12You're not average

    Population-level dietary advice can't predict your response. Genes, microbiome, life stage, and context produce tenfold variation between people eating identical food. Personalization is a way of thinking, not a shopping list.

The Nutrition Library

Deep dives for clinicians, journalists, and the genuinely curious. Optional, technical, well-sourced.

  1. 01How nutrition science actually works

    Nutrition science is a young, underfunded, methodologically constrained discipline whose tools — questionnaires, observational cohorts, surrogate endpoints — were not built for the questions reporters and policy bodies ask of it. Reading any claim requires understanding what each study design can and cannot prove.

  2. 02The metabolic-syndrome thesis: one upstream cause for many downstream diseases

    The argument that most chronic Western diseases — type 2 diabetes, heart disease, NAFLD, PCOS, hypertension, Alzheimer's, several cancers — share a single upstream defect: insulin resistance, hyperinsulinemia, and the cluster of cellular pathologies that follow.

  3. 03Big Food vs. public health

    U.S. dietary advice is shaped less by science than by a regulated political economy: USDA's dual mandate, government-enforced industry checkoffs, the GRAS loophole, industry-funded science, the tobacco playbook applied to food, and lobbying that has softened every 'eat less' message since 1977.

  4. 04The history of US nutrition guidance: why 'eat less fat' became 'eat less ultra-processed' only after 50 years

    A 130-year chronological account of how American dietary advice was built — from Atwater's calorie in 1894 through the McGovern Report, the Food Pyramid, MyPlate, and the 2020 DGAC's refusal to recommend ultra-processed-food reduction — and the political mechanisms that kept the guidance trailing the science.

  5. 05Clinical nutrition by condition: what actually changes when you have a diagnosis

    A condition-by-condition walk through what medical nutrition therapy actually entails for type 2 diabetes, NAFLD, hypertension, chronic kidney disease, gout, IBS, IBD, celiac, cardiovascular disease, and eating-disorder recovery. Physician-facing, non-prescriptive.

  6. 06Life-stage nutrition: preconception to end of life

    The nutrient priorities and feeding strategies that change at each developmental stage — preconception, pregnancy, infancy, toddlerhood, childhood, adolescence, adult years, perimenopause and menopause, older adulthood, and frailty. A generic 'healthy diet' is malpractice in a clinical encounter; each stage has its own at-risk nutrients, screening tools, and feeding architecture.

  7. 07Eating disorders and the dieting trap

    Restriction is the single strongest behavioral predictor of disordered eating. The Minnesota Starvation Experiment, weight-cycling research, and four decades of intuitive-eating data converge on one finding: the diet causes the symptoms diet culture blames on the dieter. Choosing real food over ultra-processed food is not the same behavior — the difference shows up in shame, rigidity, body distortion, and obsession.

  8. 08Planetary health and food systems

    The global food system is the single largest driver of environmental change on Earth — responsible for roughly a quarter of greenhouse-gas emissions, most freshwater withdrawal, most ocean and river eutrophication, and most biodiversity loss. The EAT-Lancet Commission and life-cycle analyses converge on the same lever: shifting away from red meat and dairy toward minimally processed plants is the high-leverage individual move. Local sourcing, recycling packaging, and avoiding plastic straws are not.

  9. 09Evaluating any nutrition claim

    A reusable seven-question checklist for assessing any nutrition claim — a TikTok, a podcast hot take, a news headline, a supplement label, a doctor's offhand remark — in under a minute. Synthesizes the study-design hierarchy, the relative-vs-absolute-risk trap, and the industry-funding signature into a tool you can run on anything.

  10. 10Cooking as a nutrition lever

    Heating raw ingredients yourself is the single highest-leverage move in nutrition: it controls portion, salt, sugar, fat, and ingredient origin in one move, and quietly retrains the palate that synthetic flavor has been deceiving.
