Egg-cellent news: An egg a day won’t increase your risk for heart disease, researchers say

March 25, 2020

Hamilton, Ontario — Contrary to some guidelines that recommend limiting your consumption of eggs over heart health concerns, results of a recent study suggest one a day is fine.

Researchers from McMaster University and Hamilton Health Sciences analyzed data from nearly 178,000 individuals across three multinational studies, which comprised residents of all income levels in 50 countries on six continents. A majority of those studied consumed one egg or fewer each day.

Results show such moderate egg intake “does not increase the risk of cardiovascular disease or mortality, even if people have a history of cardiovascular disease or diabetes,” Mahshid Dehghan, lead study author and investigator at the Population Health Research Institute of McMaster and Hamilton Health Sciences, said in a Jan. 27 press release.

Additionally, the researchers found no association between egg consumption and cholesterol. Dehghan called the results “robust and widely applicable to both healthy individuals and those with vascular disease.”

Principal study investigator and PHRI Director Salim Yusuf noted that previous studies linking eating eggs to heart disease were “relatively small or moderate” by comparison.

The study was published online Jan. 21 in the American Journal of Clinical Nutrition.
