    How 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.

    The 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.

    Big 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.

    The 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.

    Clinical 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.

    Life-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.

    Eating 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.

    Planetary 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.

    Evaluating 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.

    Cooking 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.
