Keys states there is overwhelming evidence that dietary cholesterol becomes blood cholesterol.






Important Text:

"It was Ancel Keys himself who first discredited this notion[avoid eating cholesterol to reduce accumulation in body]. Although in 1952 he stated that there was "overwhelming evidence" for the theory, he then found that no matter how much cholesterol he fed to the volunteers in his studies, the cholesterol levels in their blood remained unchanged. He found that "tremendous" dosages of cholesterol added t othe daily diet--up to 3,000 milligrams per day (a single large egg has just under 200 mg)--had only a "trivial" effect and by 1955, he had already decided that "this point requires no further consideration."

USA History
Diet-Heart Hypothesis
The diet-heart hypothesis, also known as the lipid hypothesis, proposes that there is a direct relationship between dietary fat intake, particularly saturated fat and cholesterol, and the development of heart disease. It suggests that consuming high amounts of these fats leads to an increase in blood cholesterol levels, specifically low-density lipoprotein (LDL) cholesterol, which in turn contributes to the formation of atherosclerotic plaques in the arteries. Some consider this hypothesis nothing more than wishful thinking.
Cholesterol is an animal based molecule that forms cell membranes. It's a lipid known as a sterol. Cholesterol is found in all animal foods and is healthy to eat, despite the opinions set forth by the diet-heart hypothesis. Lipoproteins carry cholesterol as well as other lipids.
