An egg a day may be fine for you after all, a new study says

According to a new study, the latest answer might have come from your mother or grandmother: all things in moderation. "Moderate consumption -- up to one egg per day -- is not associated with increased risk of cardiovascular disease," said study author Dr. Frank Hu, who chairs the department of nutrition at Harvard University's T.H. Chan School of Public Health.
The research team analyzed data from large, longitudinal studies that were following 215,000 women and men who had no major chronic disease at the start of the study.
All were asked about their egg-eating habits -- most said they ate between one and five eggs a week -- and their health was followed over a 34-year period.
Did eating eggs increase their risk for heart attacks, coronary heart disease or stroke?
Not for the vast majority. The only association between a higher intake of eggs and cardiovascular risk was for people with type 2 diabetes, a link that has been duplicated in previous studies.
What if people ate more than one egg a day?
"On average, most people don't eat more than an egg a day," Hu said. "They might eat two eggs per breakfast, but only two or three times per week. So the average consumption is actually less than one egg per day."
To verify the results, the team did a meta-analysis of studies from Europe, Asia and the United States. Combined, those studies looked at the egg-eating habits of 1.7 million people and also found that eating up to one egg a day had no negative impact on heart health.
There was more good news: Moderate egg consumption was associated with a slightly lower risk for heart disease in Asian populations, possibly because of the way Asian food incorporates eggs into recipes rather than eating them separately, he added.
The study "was meticulously conducted," said Alice Lichtenstein, the director and senior scientist at the Cardiovascular Nutrition Laboratory at Tufts University, who was not involved with the study.
The results are consistent with the American Heart Association 2019 cholesterol advisory published last year, as well as previous guidance from the 2015 Dietary Guidelines Advisory Committee, she said.
In fact, Lichtenstein added, dietary models that recommend replacing "full-fat milk, unprocessed red meat or processed red meat with eggs showed a benefit in terms of cardiovascular disease risk."
