ReThink History: Eat Real Food? Nutrition Advice
For a hundred years the U.S. government has told Americans what to eat — and the advice keeps flipping: prevent deficiency, cut all fat, sugar is the enemy, now 'eat real food' and pile on protein. This ReThink History series traces the whole arc — the dairy-reviewed food guides, Ancel Keys and the war on fat, the sugar industry's secret 1967 payment to Harvard, the rise and fall of the Food Pyramid, the diet-fad churn from Atkins to keto, the ultra-processed-food fight, and the 2025-2030 'New Pyramid' — and lands on what the best science actually says you should eat now, by age and sex. Even-handed: industry capture is the century-long constant, not any one party. Hosted by a physician who was taught almost no nutrition in medical school, then spent 42 years feeding the most fragile patients alive, one nutrient at a time. Nine episodes. AI-narrated from human-researched, primary-source dossiers. Educational, not medical advice.

Episodes
Before the Pyramid — Feeding a Country at War
Before the food pyramid there was the wartime Basic Seven and the Basic Four — America's first food guides, built to prevent deficiency under rationing, not chronic disease.
The 1977 Pivot — From Deficiency to Disease
In 1977 the McGovern committee told Americans to eat less, not just enough — and put the government at odds with the meat, dairy, and egg industries.
The Man Who Blamed Fat — Ancel Keys and the Diet-Heart Hypothesis
Ancel Keys argued saturated fat causes heart disease, and within a decade it became U.S.
The Sugar Papers — How the Sweet Industry Redirected the Blame
In 1965 the sugar industry paid three Harvard researchers, handed them the studies, and set the objective for a 1967 review that called sugar's link to heart disease 'limited' and pointed at fat instead — undisclosed.
The Pyramid Rises and Falls
The 1992 Food Guide Pyramid was pulled from the printer amid meat and dairy lobbying, retested for a year, and re-released with the meat recommendation quietly raised.
Fad After Fad — The Diet-Trend Cycle
Low-fat, Atkins, South Beach, gluten-free, paleo, keto, intermittent fasting — for forty years diet fads followed one arc: a simple promise, explosive spread past the evidence, then collapse.
The War on Processing — Ultra-Processed Food
'Ultra-processed food' reframed nutrition around how food is made.
Eat Real Food? — The 2025 Guidelines and the New Pyramid
In January 2026 the government retired MyPlate and unveiled an inverted 'New Pyramid' — protein, dairy, and healthy fats at the top — under the 'eat real food' / MAHA banner.
What Should You Actually Eat? — The Best Science by Age and Sex
The capstone: after a century of shifting advice, what does the science say now? We separate the durable consensus (more plants and fiber; less added sugar and ultra-processed food) from the numbers that change with age and sex — iron at menarche, calcium at 51, the protein debate from 0.8 to 1.6 g/kg.
