Research on moderate egg consumption in two large prospective cohort studies (nearly 40,000 men and over 80,000 women) found that up to one egg per day is not associated with increased heart disease risk in healthy individuals.  

Eggs were previously associated with heart disease risk as a result of their high cholesterol content. However, a solid body of research shows that for most people, cholesterol in food has a smaller effect on blood levels of total cholesterol and harmful LDL cholesterol than does the mix of fats in the diet. 

Furthermore, to truly assess eggs and heart health, we need to examine how they stack-up to foods we might choose in their place—the classic nutrition substitution analysis. Using some common breakfast options as an example:

While eggs may be a much better choice than sugary, refined grain-based options like sweetened breakfast cereals, pancakes with syrup, muffins, or bagels, they may fall short of other options. A bowl of steel-cut oats with nuts and berries, for example, will be a much better choice for heart health than an egg-centric breakfast. Consumption of whole grains and fruit predict lower risk of heart disease, and when it comes to protein, plant sources like nuts and seeds are related to lower cardiovascular and overall mortality, especially when compared to red meat or eggs.
