The misconceptions about Cholesterol abound, but the facts are already established. Cholesterol is vital for numerous biological functions, and dietary cholesterol does not significantly impact cholesterol levels in the body.

LDL needed by the body:
LDL occurs naturally in the body and is essential for bodily functions vital for life. Only 20% of blood cholesterol is derived through diet.60-70% of all blood cholesterol comes from production by the liver, not from pre-formed cholesterol in the foods. Reference: Turley, S.D. and Dietschy, J.M. "The Metabolism and Excretion of Cholesterol by the Liver," in The Liver: Biology and Pathology, pp. 617-642, ed. By I.M. Arias Raven Press, N.Y. 1988. 

LDL is also vital because it transports essential fatty acids into the cells. Reference: Enter the Zone, page 121.

Cholesterol structure:
EFA deficiency causes defective cholesterol and phospholipid structure – the real reason for misunderstanding cholesterol LDL.

The body regulates dietary sugar, but there is no regulator in the body for dietary cholesterol. What do you think this means?

Most cholesterol NOT produced by diet:
"With even a 30% fat diet, increasing dietary cholesterol from 319 mg to 941mg per day [close to a 300% increase], the blood LDL only increased a mere 6% [6 points]!" Reference: Metabolism 2001 May;50(5):594-597

Cholesterol and cell structure:
Cholesterol necessary for lipid bi-layer of cells. Reference: Molecular Biology of the Cell, pg. 481., Bruce Alberts, Dennis Bray, Julian Lewis, Martin Raff, ke Roberts, Keith Roberts, James D. Watson, Garland Pub, March, 1994, ISBN: 0815316194

Over 90% of cholesterol is found in the body cells. If there is not enough cholesterol in the cell membrane, the walls lose their rigidity and expand outward, due to the inner pressure of the cell, leading to possible cell damage, or destruction. Reference: Textbook of Medical Physiology, pg. 872-873, Arthur C. Guyton, John E. Hall, W B Saunders Co., January 15, 1996, ISBN: 0721659446 & Elisabeth Schafer, Ph.D., Extension Nutrition Specialist Diane Nelson, Extension Communications Specialist Iowa State University & The Consumer's Good Chemical Guide by John Emsley (Science Writer in residence at Imperial College of Science, Technology and Medicine, London), ISBN 0-552-14435-5, Corgi 1996.

Cholesterol is essential for life. Over 90% of cholesterol is found in the body cells, where it gives integrity to the cell structure and regulates the two-way flow of nutrients and waste products. Reference: The Consumer's Good Chemical Guide by John Emsley (Science Writer in residence at Imperial College of Science, Technology and Medicine, London), ISBN 0-552-14435-5, Corgi 1996. & Molecular Biology of the Cell, pg. 481., Bruce Alberts, Dennis Bray, Julian Lewis, Martin Raff, ke Roberts, Keith Roberts, James D. Watson, Garland Pub, March, 1994, ISBN: 0815316194.
