Eggs have been a crucial part of our daily diet for centuries, and it is no secret that it is a highly nutritional food item.
However, over the years, eggs have been considered unhealthy due to concerns about high cholesterol levels and fears of coronary heart disease. In this article, we will discuss whether egg consumption affects your heart health.
The Nutritional Value of Eggs
Eggs are a rich source of proteins, vitamins, and minerals. One large egg contains about 6 grams of high-quality protein and essential amino acids, which are essential nutrients for building and repairing muscles.
Eggs also contain vitamins A, D, E, K, B6, B12, folate, and calcium. Moreover, They also consist of iron, zinc, and phosphorous.
The Connection Between Cholesterol and Heart Disease
Cholesterol is a fat-like substance that is crucial for several essential body functions, such as hormone production and cell membrane construction. However, when consumed in excess, it increases the risk of heart disease.
There are two types of cholesterol- LDL (Low-density lipoprotein) and HDL (High-density lipoprotein). LDL is also referred to as ‘bad’ cholesterol that can clog arteries and put you at risk of a heart attack or stroke. Meanwhile, HDL is known as ‘good’ cholesterol as it helps in transporting LDL out of the bloodstream.
The Cholesterol Content in Eggs
Egg yolks are known to be high in cholesterol, with one large egg providing172 mg of cholesterol, which is more than half of the daily recommended limit for healthy individuals (300 mg).
Therefore, consuming several eggs every day can contribute significantly to the LDL cholesterol levels in your body.
The Controversy Around Egg Consumption and Heart Health
The scientific literature around egg consumption and heart health is extensive. However, there is still a lack of clarity in the matter, and opinions among health professionals and researchers differ.
Some studies show that consuming eggs, even in high quantities, does not necessarily increase the risk of heart disease. Others suggest that moderate egg consumption can have a neutral effect on heart health. In contrast, some studies claim that egg consumption, even in small amounts, increases the risk of heart disease.
Why Egg Consumption Might be Harmful to Heart Health?
Eggs contain choline, an essential nutrient for brain health.
However, recent studies have reported that choline produces trimethylamine-N-oxide (TMAO) in the gut, which promotes the accumulation of cholesterol in the walls of arteries, ultimately leading to heart disease. TMAO produced by choline-rich foods such as eggs can put you at higher risk of heart disease.
How Many Eggs Can You Consume Safely?
Based on the scientific literature, experts recommend that people with high cholesterol, type 2 diabetes, and other risk factors for heart diseases should limit the consumption of eggs.
Healthy people should aim for a daily limit of one egg or two egg whites, according to the American Heart Association. However, it is essential to consider an individual’s overall dietary pattern, lifestyle, and overall health before determining the safe limit of egg consumption.
Conclusion
Eggs are highly nutritious and an excellent source of essential vitamins and protein. However, they are also a significant source of cholesterol, which can contribute to heart disease if consumed in excess.
The scientific literature regarding the connection between egg consumption and heart health remains divided. Experts recommend that individuals with high cholesterol or other risk factors for heart disease should limit their egg consumption.
Individuals should also consider their overall dietary pattern, lifestyle, and overall health before determining their safe limit of egg consumption.
