Eating egg yolk 'almost as bad as smoking' for atherosclerosis

14 August 2012

Eating egg yolk could be almost as bad as smoking cigarettes when it comes to an increased build-up of carotid plaque, which is a risk factor for stroke and heart attack.

Research published online in the journal Atherosclerosis revealed that regular consumption of egg yolks is around two-thirds as bad as smoking when it comes to coronary artery disease.

Scientists found that carotid plaques increased with age after participants reached 40, but rose exponentially with years of smoking and consuming egg yolks.

This means that both smoking and eating egg yolks were found to both increase atherosclerosis much more than age did.

Furthermore, those consuming three or more yolks per week had significantly more plaque areas than those who consumed two or fewer yolks each week.

Dr. Spence, a professor of neurology at Western's Schulich School of Medicine & Dentistry and the director of its Stroke Prevention and Atherosclerosis Research Centre at the Robarts Research Institute, said that it has long been known that a high cholesterol intake increases the risk of cardiovascular events, adding that eggs have extremely high cholesterol content.
