Eggs have long been considered one of nature’s most nutritious foods. They’re affordable, versatile, rich in protein, and packed with essential vitamins and minerals. Yet every few years, headlines emerge warning that eggs—particularly the yolks—may increase the risk of heart disease.
So what’s the truth?
Recent studies have explored the relationship between eggs, cholesterol, heart health, and overall wellness. While some research has raised concerns about excessive egg consumption in certain individuals, most nutrition experts agree that eggs can still be part of a healthy diet for many people when consumed in moderation.

Here’s what current science says about egg yolks, cholesterol, and heart health.
Why Egg Yolks Have Been Controversial
The concern surrounding egg yolks comes primarily from their cholesterol content.
A single large egg contains approximately 185 milligrams of cholesterol, most of which is found in the yolk. For decades, health experts believed that eating cholesterol-rich foods directly increased blood cholesterol levels and heart disease risk.
However, more recent research has shown that the relationship is far more complex.
For most healthy individuals, dietary cholesterol has a relatively modest effect on blood cholesterol compared to factors such as:
- Overall diet quality
- Saturated fat intake
- Physical activity
- Body weight
- Genetics
- Smoking status
