In a February 2009 Nutrition Bulletin paper entitled "Eggs and Dietary Cholesterol - Dispelling the Myth," Prof. Bruce Griffin and Dr. Juliet Gray reviewed studies of egg consumption, dietary cholesterol and heart disease risk. The following conclusions were drawn:
There appears to be an association between dietary cholesterol and coronary heart disease because saturated fat and cholesterol co-exist in fatty foods.
Dietary cholesterol can increase LDL cholesterol a small amount, but the effect is clinically insignificant, and the effect of saturated fat is far greater.
Evidence does not suggest the small increase in blood cholesterol caused by dietary cholesterol increases the risk of heart disease.
Eating eggs may increase HDL cholesterol, counteracting the effect of LDL cholesterol on heart disease risk.
