Dietary cholesterol is not a big concern for most people.
A boiled egg contains about 186 mg of cholesterol, mostly in the yolk. Research shows that dietary cholesterol has a minimal impact on blood cholesterol levels for most people. The 2020–2025 U.S. Dietary Guidelines no longer restrict dietary cholesterol, but they recommend moderate consumption.
However:
People with type 2 diabetes, familial hypercholesterolemia, or a history of heart disease may need to limit their intake of egg yolks. In such cases, it’s a good idea to talk to your doctor. -
Boiled eggs may be a better choice than fried ones.
Boiling avoids added saturated fats and oxidized oils, which can damage blood vessels. This makes boiled eggs a more heart-safe option compared to eggs fried in butter or processed fats.
Conclusion
Eating 1 boiled egg a day in the morning is generally safe and may support blood vessel health, especially as part of a balanced diet rich in fruits, vegetables, whole grains, and healthy fats. If you have existing heart disease, diabetes, or high cholesterol, it’s wise to discuss egg intake with a doctor or dietitian.
