Researchers at Northwestern Medicine say a large new study has found that adults who ate more eggs and cholesterol had a significantly higher risk of cardiovascular disease and death from any cause. That's according to a large new study published today that links higher consumption of dietary cholesterol with cardiovascular disease and death. The sunny-side down news comes from Northwestern University researchers, who analyzed 30,000 USA adults over three decades.
They also found that eating three or four eggs a week was associated with a 6 percent higher risk of cardiovascular disease incidents and 8 percent higher risk of death generally.
"Considering the negative consequences of egg consumption and dietary cholesterol in the setting of heart-healthy dietary patterns, the importance of limiting intake of cholesterol-rich foods should not be dismissed", he concluded.
As we speak, eggs are one of the most consumed foods, worldwide.
Sherman says if you're in the habit of eating a healthy diet, full of lots of plant-based, fiber-rich foods, then "eggs are a welcome part of the diet".
The findings stand in contrast to past studies that suggested cholesterol had little to no association with heart disease, and that saturated fat carried the greatest risk, Lauri Wright, spokeswoman for the Academy of Nutrition and Dietetics, who did not work on the study, told Newsweek. However, a better compromise to reap the benefits while reducing the risks would be to eat them in moderation.
The researchers said their study looked at almost 30,000 racially and ethnically diverse United States adults from six separate studies with as much as 31 years of followup. On average, participants were followed for about 17 years. It will be published on March 15 in JAMA and the following days to different worldwide research centers.More news: Barcelona's Dembele out for month after hamstring injury against Lyon
Senior author Norrina Allen, a preventive medicine specialist, noted that the study lacks information on whether participants ate eggs hard-boiled, poached, fried, or scrambled in butter, which she said could affect health risks.
"I'm not advocating people take them completely out of their diets", she said.
"The take-home message is really about cholesterol, which happens to be high in eggs and specifically yolks", one of the authors, Norrina Allen, Ph.D., an associate professor of preventive medicine at Northwestern University Feinberg School of Medicine, said in a statement. "We hope that in future research we are able to have a look at how adjustments in eating regimen over the long-term could also be impacting this threat for coronary heart illness", Allen says.
Are eggs good or bad?
Moreover, Andersen said, the study is observational, which means it can only show there's an association between egg consumption and heart disease but it can't prove eggs are the culprit.
The study can not prove cause and effect and is unlikely to be the last word on the matter, but experts said moderation was probably the safest course, advising no more than three or four eggs a week.
Over time, there were 5,400 cardiovascular-related adverse outcomes, including 2,088 fatal and non-fatal heart disease events, 1,302 fatal and non-fatal stroke events, 1,897 fatal and non-fatal heart failure events and 113 other cardiovascular disease deaths. Moderation, he added, is "less than one egg a day on average, including eggs in foods such as bread".
