When it comes to nutrition and cardiovascular health, few foods generate as much debate as eggs. On one hand, eggs are a nutrient-dense source of high-quality protein, choline, lutein, and zeaxanthin, nutrients that support brain and eye health. On the other hand, eggs remain one of the richest sources of dietary cholesterol.
This raises an important question: Do eggs meaningfully increase cardiovascular disease (CVD) risk? The most accurate answer is that your overall eating pattern, not any single food, is what matters most.
What Large Studies Show About Effs and Heart Disease
Multiple high-quality analyses have examined whether eggs increase cardiovascular risk. When researchers adjust for factors such as saturated fat intake, total calories, fiber consumption, body weight, and lifestyle habits, eating up to one egg per day is not associated with higher cardiovascular disease risk.
A 2020 pooled analysis of U.S. cohorts found no significant association between moderate egg intake and cardiovascular disease when diet quality was considered (Drouin-Chartier et al., 2020). Likewise, the multinational PURE study reported no increased cardiovascular risk with up to one egg per day, even across diverse global populations (Dehghan et al., 2020).
Taken together, these studies show that dietary cholesterol from eggs plays a relatively small role in cardiovascular risk, especially compared with saturated fat, refined carbohydrates, and overall eating patterns.
Expert Guidance: What the America Heart Association Recommends
The American Heart Association emphasized this perspective in its 2020 dietary guidance. The authors concluded that dietary cholesterol is not a major driver of heart disease, and that cardiovascular risk is influenced far more by the overall diet—particularly higher intake of fruits, vegetables, whole grains, lean proteins, and unsaturated fats (Sacks et al., 2020).
In other words, how eggs fit into your total diet matters far more than the cholesterol number itself.
New Clinical Trial: Eggs Within a DASH Diet
A recent controlled feeding trial added new insight. Njike and colleagues (2024) evaluated the effects of adding eggs to the DASH diet, a dietary pattern widely recognized for lowering blood pressure and improving lipid profiles.
In adults with elevated LDL cholesterol, participants followed the DASH diet alone and then the DASH diet plus two eggs per day for eight weeks. Researchers found:
- No adverse changes in LDL cholesterol
- No changes in blood pressure
- No increases in inflammatory markers
In short, including eggs within a heart-healthy eating pattern did not worsen cardiovascular risk factors.
So, Are Eggs Heart Healthy?
For most people, up to one egg per day can fit into a cardioprotective diet, particularly one that emphasizes vegetables, fruits, whole grains, legumes, nuts, seeds, and healthy fats.
Importantly, context matters. Eggs paired with bacon, buttered white toast, and processed meats contribute to a very different dietary pattern than eggs served with sautéed vegetables, beans, or whole-grain bread.
Decisions about egg intake can also be personalized based on:
- LDL-C and apoB levels
- Lipoprotein(a)
- Genetic factors (e.g., APOE genotype)
- Individual cholesterol response
- Overall dietary pattern
For most adults, moderate egg consumption within a nutrient-rich dietary pattern does not increase cardiovascular disease risk.
