Ancel Keys
1904 – 2004 · United States · Nutrition, Public Health
The Seven Countries Study put diet at the centre of cardiovascular prevention.
Core concepts
- Diet–heart hypothesis linking saturated fat, serum cholesterol and coronary disease
- Cross-population epidemiology as a method in nutrition
- The Mediterranean diet described as a coherent dietary pattern
Key writings and teachings
- Seven Countries Study (from 1958) and its multi-decade follow-ups
- Eat Well and Stay Well (1959) and How to Eat Well and Stay Well the Mediterranean Way (1975)
- The Biology of Human Starvation (1950), from the Minnesota Starvation Experiment
Influence on modern practice
Keys's work set the framework for cardiovascular dietary guidance across most of the world for half a century and made the Mediterranean pattern a global public-health recommendation, later supported by the PREDIMED trials. His country selection and the strength of the saturated-fat claim remain actively disputed in the nutrition literature.

What modern research says
- EstablishedCheck the literature — PubMed ↗
PREDIMED and its reanalysis show a Mediterranean diet reduces major cardiovascular events.
- ContestedCheck the literature — PubMed ↗
The strength of the saturated-fat-to-mortality link and his country selection remain actively disputed.

- Dietary-pattern scoring instruments used in clinical trials
Real-world uses
