Warnings against saturated fat on heart health need to be revisited as flaws were revealed in the seminal 1950s studies on which these warnings were based, according to new research coming out of the Ateneo de Manila University.

In 1953, spurred by an apparent surge in heart disease in the US, physiologist Ancel Keys published a study that introduced the “lipid-heart hypothesis.” He claimed without evidence that high saturated fat and cholesterol in the diet raise cholesterol levels in the blood and contribute to heart disease. He developed what is now known as the Keys equation, where he sought to mathematically predict serum cholesterol levels based on saturated fat and cholesterol intake.
