Daily Egg Consumption May Not Be Associated With CVD

A team of researchers from the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences analyzed data from three large, long-term multinational studies, and found that there likely is no heart disease in consuming eggs.

Given that the majority of individuals in the study consumed one or fewer eggs per day, it would be safe to consume this level, says Mahshid Dehghan, PhD, first author on the study and a PHRI investigator.

“Moderate egg intake, which is about one egg per day in most people, does not increase the risk of cardiovascular disease or mortality even if people have a history of cardiovascular disease or diabetes,” she says.

“Also, no association was found between egg intake and blood cholesterol, its components, or other risk factors. These results are robust and widely applicable to both healthy individuals and those with vascular disease.”

The details are published in The American Journal of Clinical Nutrition.

Although eggs are an inexpensive source of essential nutrients, some guidelines have recommended limiting consumption to fewer than three eggs a week due to concerns they increase the risk of CVD.

Previous studies on egg consumption and diseases have been contradictory, says Salim Yusuf, MD, DPhil, MRCP, principal investigator of the study and director of PHRI.

“This is because most of these studies were relatively small or moderate in size and did not include individuals from a large number of countries,” he says.

The researchers analyzed three international studies conducted by the PHRI. Egg consumption of 146,011 individuals from 21 countries was recorded in the PURE study and in 31,544 patients with vascular disease from the ONTARGET and the TRANSEND studies.

The data from these three studies involved populations from 50 countries spanning six continents at different income levels, so the results are widely applicable, Yusuf says.
