What Should I Know?
Cholesterol from eggs does not raise blood cholesterol levels in everyone.
For most healthy adults, consuming 1–2 eggs per day can be part of a balanced diet.
Eggs contain around 200 mg of cholesterol per egg, but saturated fat has a greater effect on raising LDL cholesterol.
Around 30% of people absorb more cholesterol from the gut than others.
The impact of eggs on heart health depends on the overall dietary pattern, not on egg intake alone.
Why Does It Matter?
For many years, eggs were directly linked to high cholesterol and heart disease. This led to the unnecessary restriction of a nutrient-dense food.
However, eggs provide high-quality protein, vitamins, minerals, choline, and antioxidants. Understanding the science correctly helps prevent both unnecessary dietary restrictions and misleading health perceptions.
What Does Science Say?
Scientific evidence shows that most blood cholesterol is produced by the body rather than coming directly from food. Dietary cholesterol is not the only, nor the strongest, factor influencing blood cholesterol levels.
Research indicates that saturated fats have a stronger effect on raising LDL cholesterol, often referred to as “bad” cholesterol, than dietary cholesterol itself. In contrast, diets rich in polyunsaturated fats help lower LDL cholesterol.
For this reason, the effect of eggs should always be considered within the context of overall diet and fat intake.
How Does It Work?
When eggs are consumed, cholesterol is absorbed in the small intestine. However, the degree of absorption varies from person to person.
In some individuals, the transport systems that move cholesterol into the bloodstream are more active. These individuals absorb more cholesterol and are referred to as “high absorbers.” In this group, cholesterol-rich foods such as eggs may lead to greater increases in LDL cholesterol and ApoB levels.
ApoB reflects the number of LDL-like particles circulating in the blood and is considered a strong indicator of cardiovascular risk.
Common Misconceptions
The idea that “eggs are bad for the heart because they contain cholesterol” is an oversimplification.
This view overlooks the following facts:
Most blood cholesterol is produced by the body.
Saturated fats have a stronger impact on LDL cholesterol than dietary cholesterol.
Genetic differences influence individual cholesterol responses.
Physical activity, body weight, and overall diet quality have a much greater effect on cholesterol levels than egg consumption alone.
As a result, people eating the same number of eggs may experience very different effects on their blood cholesterol levels.
Why Are We Sharing This?
We share this content to show that the relationship between eggs and cholesterol is not one-dimensional. Our aim is neither to promote nor discourage a specific food, but to offer a science-based and contextually informed perspective.
When it comes to heart health, what matters most is not a single food, but the overall quality of the diet and lifestyle behaviors.
