Eggs are a staple ingredient in my fridge. I use them in my baking and I sometimes eat them for breakfast. Over the years, however, I would often hear many mixed messages about their health benefits such as that eating too many eggs would raise your cholesterol. Because of this, I would often limit how many I eat. That said, I was interested to read a recent study (1) in which researchers found that eating an egg a day may lower cardiovascular disease risk. Researchers of this study, which included over 400,000 adults in China, found that those participants who consumed up to less than one egg per day had an 18% lower risk of cardiovascular disease death compared to those participants who do not consume eggs.
According to an article (2) in the Harvard Health Letter, Dr. Anthony Komaroff, MD, Professor of Medicine at Harvard Medical School, asserts that an egg a day does not increase your risk for a heart attack. Dr. Komaroff believes it is wise for individuals with diabetes or at high risk for (or already have) heart disease to consume no more than 3 eggs per week. Further, he describes that while eggs were known for having lots of cholesterol which can increase cardiovascular disease risk, research has shown that most of our body’s cholesterol comes from our liver and not what we eat. Research has also found eggs to have many healthy nutrients that are good for the body. Finally, Dr. Komaroff describes the importance of considering the other foods one eats with their eggs, such as foods with saturated fat like butter, bacon, or muffins that can raise blood cholesterol more than eggs themselves.
