Elevated serum cholesterol is a major contributor to cardiovascular disease (CVD), which is responsible for ~1/3 of all deaths in the US. However, about 50% of those who experience heart attacks have normal cholesterol levels. Cholesterol is carried in lipoproteins (HDL, LDL, and VLDL) and the amount in circulation is used to evaluate CVD risk. However, the particle size and density of lipoprotein subfractions may be more predictive for atherogenesis than their total levels. Dietary fatty acids are well recognized modulators of lipoproteins, and ultimately CVD risk. Saturated and trans fatty acids have a negative effect on CVD risk while poly- and monounsaturated fatty acids (PUFA, MUFA) appear to be protective. The Mediterranean Diet (Med Diet) decreases atherogenic lipoproteins and reduces systemic inflammation. It is unknown how high cholesterol intake within a Med Diet will affect these parameters, although recent evidence implies that the fatty acid content of the diet is more important than the cholesterol content. Therefore, this project will evaluate the daily inclusion of whole eggs, a high cholesterol food, in the Med Diet on lipid profiles, lipoprotein particle size and density and biomarkers of systemic inflammation.
