Egg Consumption and Cardiovascular Disease Risk
Research consistently shows that moderate egg consumption—up to one egg per day—is not associated with an increased risk of cardiovascular disease (CVD), coronary heart disease (CHD), or stroke in the general population Godos2020Rong2013Drouin-Chartier2020+6 MORE. Large-scale studies and meta-analyses involving millions of participants have found no significant link between eating eggs and higher rates of CVD events or mortality. In some populations, particularly in Asia, moderate egg consumption may even be linked to a slightly lower risk of CVD and stroke Drouin-Chartier2020Xu2019Qin2018.
Dose-Response and Population Differences
Most studies indicate that consuming up to six eggs per week, or about one egg per day, does not increase CVD risk and may be associated with a small reduction in risk compared to no egg consumption Godos2020Rong2013Drouin-Chartier2020+4 MORE. However, higher intakes—more than one egg per day—do not show clear additional benefits and, in some cases, may be linked to increased risk of heart failure . The relationship between egg consumption and health risks can vary by region, with some studies showing a protective effect in Asian populations but not in Western countries Drouin-Chartier2020Xu2019Qin2018.
Egg Consumption and Diabetes
Egg consumption appears to have a different impact on people with diabetes. Several studies report that higher egg intake is associated with an increased risk of CVD among diabetic individuals Rong2013Li2013Shin2013. Additionally, there is evidence of a positive association between egg consumption and the risk of developing type 2 diabetes in the general population Li2013Shin2013. This suggests that people with diabetes or at high risk for diabetes may need to be more cautious with egg consumption.
All-Cause Mortality and Subgroup Findings
Some recent analyses suggest a modest increase in all-cause mortality with higher egg consumption, especially among older adults, Americans, and those with hyperlipidemia . However, these findings are not consistent across all studies, and the overall increase in risk is small. No significant association has been found between egg consumption and mortality from ischemic heart disease or stroke Xu2019Wancheng2022.
Nutritional Value and Dietary Recommendations
Eggs are a nutrient-rich, affordable food and can be part of a balanced diet for most healthy individuals . Current evidence supports including eggs in moderation—up to one per day—without increasing CVD risk for the general population Godos2020Drouin-Chartier2020Xu2019+2 MORE. However, individuals with diabetes or those at higher risk for CVD should consult healthcare professionals for personalized advice.
Conclusion
For most people, moderate egg consumption does not increase the risk of cardiovascular disease or mortality and may even offer some protective benefits, especially in certain populations. However, people with diabetes or at higher risk for CVD should be more cautious. Overall, eggs can be enjoyed as part of a healthy, balanced diet.
