Eating up to three eggs per day does raise some types of cholesterol, but does not significantly raise levels of LDL types know to clog arteries.

“We found that the dietary cholesterol in eggs does raise the LDL-1 and LDL-2, but it does not impact the small, LDL-3 through LDL-7, particles that are the greatest threat for cardiovascular disease risk,” says Maria Luz Fernandez, a researcher at the University of Connecticut.

She says the findings may help explain why previous studies haven’t shown a consistent relationship between increases in LDL cholesterol levels, such as those associated with eating eggs, and an increasing risk of heart disease.
