Dr. David Spence, head of a study on the effects of egg yolks and cardiovascular health for the Western University in London, Ontario says that if you are at risk for vascular disease you should avoid eating egg yolks.
The study has shown that egg yolks have an affect on the cardiovascular system similar to that of smoking, including clogging up the carotid artery and increasing the risk of stroke.
The study was conducted among 1200 people of mixed gender taking part in an initiative to help stop heart disease. Ultrasounds showed that artery plaque increased in similar amounts with those that ate eggs and those that smoked.
“The study also found those eating three or more yolks a week had significantly more plaque area than those who ate two or fewer yolks per week,” the press release around the study says.
Not everyone is convinced of the results.
Dr. Spence explained to the Vancouver Sun, that this is actually nothing new, though.
“The mantra ‘eggs can be part of a healthy diet for healthy people’ has confused the issue. It has been known for a long time that a high cholesterol intake increases the risk of cardiovascular events, and egg yolks have a very high cholesterol content. In diabetics, an egg a day increases coronary risk by two to five-fold,” he said.
Karen Harvey, a nutrition officer and registered dietician with the national organization, added that it’s unfair to compare egg yolks with smoking.
“It goes without saying that smoking is considered one of the most harmful activities when it comes to your personal health and wellness,” Harvey said.
“We have decades of clinical, scientific research that demonstrates no link between egg consumption and an increased risk for heart disease.”
The study was published online in the journal Atherosclerosis.
