Do Eggs Really Harm Your Heart? Let’s Set the Record Straight
For years, eggs have been caught in a whirlwind of health debates. One day, they’re called a “nutritional powerhouse,” and the next, they’re labeled as a heart attack waiting to happen. Many people still believe that eating eggs raises cholesterol levels, clogs arteries, and increases the risk of heart disease. But is this actually true? Or is it just another myth that science has already debunked?
If you’ve been avoiding eggs because you’re worried about your heart, it’s time to take a closer look at the latest research. You might be surprised to learn that eggs are not the villain they were once thought to be. In fact, they can be part of a heart-healthy diet when consumed in moderation. Let’s dive into the facts, bust the myths, and uncover the real relationship between eggs and heart health.

The Cholesterol Controversy: Where Did the Fear Come From?
The belief that eggs are bad for the heart largely stems from their cholesterol content. A single large egg contains around 186 milligrams of cholesterol, which is primarily found in the yolk. Decades ago, scientists assumed that eating cholesterol-rich foods would directly increase blood cholesterol levels, leading to a greater risk of heart disease. Based on this assumption, health organizations like the American Heart Association (AHA) once recommended limiting dietary cholesterol intake, which led to eggs being unfairly demonized.
However, our understanding of cholesterol and heart disease has evolved significantly. Research now shows that dietary cholesterol has much less impact on blood cholesterol levels than previously thought. The body carefully regulates its cholesterol levels, producing more when dietary intake is low and producing less when intake is high. For most people, consuming cholesterol-rich foods like eggs does not significantly raise their blood cholesterol or increase the risk of cardiovascular disease.
What Science Says: Eggs Are Not the Enemy
In 2015, the U.S. Dietary Guidelines Advisory Committee officially removed the daily cholesterol limit, acknowledging that there was no strong evidence linking dietary cholesterol to heart disease in the general population. This decision was based on extensive research showing that saturated fats and trans fats—not dietary cholesterol—are the primary dietary culprits that contribute to high LDL (“bad”) cholesterol and an increased risk of heart disease.
Dr. Jeremy London, a leading cardiothoracic surgeon, recently posed the question to his large social media following: “Are eggs bad for your heart?” His response was straightforward: “Eggs are one of nature’s most perfect foods. They provide high-quality protein, essential nutrients, and do not negatively impact heart health for most people.”
So why does the misconception persist? It’s likely due to outdated information still being circulated, along with the tendency to oversimplify nutrition science. The truth is that overall diet quality matters far more than fixating on a single food like eggs.
Eggs: A Nutritional Powerhouse
Eggs are much more than just cholesterol. They are packed with essential nutrients that support heart health and overall well-being:
- High-Quality Protein: Each egg contains about 6 grams of complete protein, providing all nine essential amino acids needed for muscle maintenance, immune function, and tissue repair.
- Choline: This vital nutrient is crucial for brain health, memory function, and liver metabolism. Many people don’t get enough choline in their diets, and eggs are one of the best sources.
- Lutein and Zeaxanthin: These powerful antioxidants found in egg yolks help protect against age-related macular degeneration and improve eye health.
- Omega-3 Fatty Acids: Eggs from pasture-raised hens or omega-3-enriched eggs provide beneficial fats that support heart and brain health.
- Vitamin D: Eggs are one of the few natural sources of vitamin D, which plays a crucial role in bone health, immune function, and mood regulation.
Contrary to popular belief, the yolk is where most of these nutrients are concentrated. While egg whites are a great source of protein, skipping the yolk means missing out on a wealth of essential vitamins and minerals.
Choosing the Healthiest Eggs
Not all eggs are created equal. If you want to maximize the health benefits of eggs, consider the following tips when shopping:
- Pasture-Raised or Free-Range Eggs: These eggs often have higher levels of omega-3 fatty acids and vitamin D compared to conventionally raised eggs.
- Organic Eggs: These eggs come from hens raised without antibiotics or synthetic hormones, making them a cleaner choice.
- Minimize Cooking Oils: Frying eggs in butter or vegetable oils can introduce unhealthy fats. Opt for boiled, poached, or lightly scrambled eggs with minimal added fat.
Harvard’s Take on Eggs and Heart Health
A recent study published by Harvard Health further confirms that eggs are not the heart-harming food they were once believed to be. The researchers found that while eggs contain cholesterol, they do not significantly impact blood cholesterol levels or increase the risk of heart disease in healthy individuals.
The study emphasized that the real dietary culprits for heart disease are excess saturated fats, trans fats, and added sugars—often found in processed and fast foods. The key takeaway? A well-balanced diet, rather than avoiding eggs, is the best way to support heart health.
The Bottom Line: Should You Eat Eggs?
The verdict is in—eggs are not only safe to eat but also offer numerous health benefits when included in a balanced diet. If you’re generally healthy, eating one to two eggs per day is unlikely to have any negative impact on your heart. However, if you have a preexisting heart condition or high cholesterol, consult your doctor to determine the best dietary choices for your specific needs.
So go ahead and enjoy your eggs—scrambled, boiled, or poached. Just be mindful of how you prepare them and pair them with heart-healthy foods like vegetables, whole grains, and healthy fats.

Eggs have been unfairly criticized for years, but science is finally setting the record straight. If you’re still hesitant about including eggs in your diet, remember that moderation and balance are key. Instead of fearing cholesterol, focus on reducing processed foods, trans fats, and excessive sugar intake. Your heart will thank you!
