Ancel Benjamin Keys (January 26, 1904 – November 20, 2004) was an American physiologist who studied the influence of diet on health. In particular, he hypothesized that replacing dietary saturated fat with polyunsaturated fat reduced cardiovascular diseases .

Ancel Keys (1904 – 2004) launched the Seven Countries Study in 1958, after exploratory research on the relationship between dietary pattern and the prevalence of coronary heart disease in Greece, Italy, Spain, South Africa, Japan, and Finland. Out of all his scientific accomplishment, the SCS is arguably the most important.

Ancel Keys pioneered the field of quantitative human biology, combining research in physiology, nutrition, and public health. An experimentalist and epidemiologist, he made lasting theoretical and practical contributions across diverse topics on health.

This review examines the historical events and scientific intrigues that have surrounded Ancel Keys's major classical studies that have ensured him a central place in the history of medical science. Keywords: Seven Countries Study; atherosclerosis; …

Starting in the 1940s pioneering American physiologist Ancel Keys helped establish the epidemiological link between cholesterol and cardiovascular disease. Once Keys and others clarified the role of dietary saturated fat in disease development, early intervention studies examined the effects of diet and drug therapy.

Ancel Keys. The Seven Countries Study is an epidemiological longitudinal study directed by Ancel Keys at what is today the University of Minnesota Laboratory of Physiological Hygiene & Exercise Science (LPHES).

In addition to his role in establishing modern cardiovascular disease (CVD) epidemiology, Ancel Keys (born on January 26, 1904) is closely associated with two famous "diets," one loathed by soldiers and the other beloved by health-conscious and taste-conscious diners.

Jan 26, 2021 · Ancel Keys, whose life spanned over 100 years (1904–2004), made a wealth of seminal scientific and public health contributions.

Dec 18, 2004 · Keys became interested in cardiovascular research and founded the Seven Countries Study to refute early scepticism about links between heart disease, cholesterol, and diet.
