Consuming one egg daily is not tied to higher blood cholesterol levels and cardiovascular disease, even for individuals with a history of such conditions, a new study has found.
Prior to the finding, there has been lots of argument on whether or not daily egg consumption can be considered healthy for older adults, as much research had established its link to cardiovascular diseases.
Researchers at the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences, however, conducted their findings which counter old-school nutritional guidance.
The study, published in the journal American Journal of Clinical Nutrition, analyzed data from three large multinational studies. It involved over 177,000 healthy and vascular disease participants, spanning people from a total of 50 countries and six continents at different income levels.
With the majority of individuals in the study consuming one or fewer eggs per day, the results suggested there’s no harm from consuming eggs.
“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,” Mahshid Dehghan, author of the study, said.
“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.”
Harvard Medical School’s 2017 research had recommended no more than one egg daily or three per week for diabetes patients.
