Does eating eggs every day increase LDL cholesterol and heart disease risk, or are eggs safe for most healthy adults?
Full answer body
Expanded summary
Scientific evidence on the relationship between egg consumption, LDL cholesterol levels, and heart disease risk is mixed. While some studies indicate that consuming eggs may raise LDL cholesterol in hyper-responders or high-risk individuals, others suggest that moderate egg intake is not consistently linked to increased cardiovascular event risk for most healthy adults. Observational studies like the one published in JAMA found a significant association between dietary cholesterol from eggs and higher risk of incident cardiovascular disease events. However, Harvard Health notes that for many people, the cholesterol in one egg a day is generally safe. Limitations include potential confounding factors in observational studies and variations in individual cholesterol responses.

What the Research Shows
Scientific evidence on the impact of egg consumption on LDL cholesterol and heart disease risk is mixed. Some studies suggest that eggs can raise LDL cholesterol in certain individuals, while others indicate that moderate egg intake may not significantly increase cardiovascular event risk for most healthy adults. A study published in JAMA found a significant association between dietary cholesterol from eggs and higher risk of incident cardiovascular disease events. However, Harvard Health states that the cholesterol in one egg a day is generally safe for most people.
Potential Benefits
- Eggs can be a nutritious and heart-healthy food when enjoyed as part of a balanced diet.
Risks and Limitations
- Observational studies may be subject to confounding factors.
- Individual cholesterol responses to egg consumption can vary.
Disagreements and Caveats
Some researchers argue that eggs can raise LDL cholesterol in hyper-responders or high-risk individuals, while others suggest that moderate egg intake is not consistently associated with higher cardiovascular event risk for most healthy adults.
Who Should Be Careful
- Individuals with diabetes or high baseline cardiovascular risk may need to monitor their egg consumption.
Bottom Line
Evidence on the impact of eggs on LDL cholesterol and heart disease risk is mixed, with some evidence suggesting potential harm for certain individuals. It is advisable for high-risk individuals to consult healthcare providers regarding egg consumption.
