People have always considered eggs as the gold standard food due to the protein, vitamins, and essential nutrients it offers the body. However, people have not gotten over arguments persisting on whether it is the egg white or the yolk that is healthier for consumption. Since everyone is on the lookout for losing weight, gaining muscles, and having a healthier diet, it becomes quite helpful to understand the differences between egg whites and egg yolk to incorporate eggs for a healthier meal.
Let's explore the nutritional differences between egg whites and yolks, weigh the pros and cons of each, and answer the question: Which is better for a person's health today: egg white or egg yolk?
The Anatomy of an Egg: White vs. Yolk
However, let's start with what an egg is made of because this information is fundamental to any discussion about nutrition. A standard large egg consists of two parts:
- Egg White (Albumen): This is the thin transparent layer next to the yolk and turns white and stiff when the eggs are cooked. Egg whites are more water and proteins.
- Egg Yolk: The creamy, golden-yellow ring in the center of the egg contains fats, vitamins and minerals, and cholesterol.
Every part has its specific nutritional value, but is it the second component worse or better than the first one? To answer this question we must begin with the specifics.
Egg whites
They contain protein, caloric content, fat content, and the fact that it contains no yolk. For those observing caloric intake or trying to shed extra kilos, egg whites become a great source of low-calorie protein as compared to other protein foods.
Some egg white peptides have also been discovered to possess ACE inhibitor effects that would indicate their blood pressure lowering effects like the usual blood pressure lowering drugs. It seems, however, that much more information is still required in order to establish whether whole egg white proteins have this impact.
Here is an overview of the nutrition found in one large egg white:
- Calories: 17
- Protein: 3.6 grams
- Fat: 0 grams
- Cholesterol: 0 mg
- Calcium: 4% of the RDI
- Potassium: 1% of the RDI
- Magnesium: 1% of the RDI
- Vitamin A: 0% of the RDI
- Vitamin B2: 2% of the RDI
- Vitamin B12: 0% of the RDI
Egg Yolks
Yolks have all the healthy fats, vitamins, and minerals that we, as consumers, get from eggs. Egg yolks somehow become viewed in a negative standard due to where the greatest majority of the fat and cholesterol are found. But fat in yolks is good for health and necessary for countless bodily functions.
Egg yolk, therefore, has more fat and calories than egg white. But most of it comes from healthy monounsaturated and polyunsaturated fats. In a survey, it was found that this type of fat helps to raise blood cholesterol levels.
Furthermore, 79% of the overall protein and all the vitamins and minerals in eggs are present in the yolk. Some of the nutrients that are only present in the egg yolk are Vitamin D, Vitamin E, Vitamin A, Choline, Selenium, Calcium, Iron, Phosphorus, and Zinc.
It is also rich in antioxidants known as carotenoids, primarily lutein and zeaxanthin. Research has also shown that taking egg yolks increases blood levels of both lutein and zeaxanthin to decrease the incidences of eye-related ailments such as cataracts and macular degeneration.
Here is an overview of the nutrition in one large egg yolk:
- Calories: 55
- Protein: 2.7 grams
- Fat: 4.5 grams
- Cholesterol: 184 mg
- Calcium: 4% of the RDI
- Iron: 4% of the RDI
- Potassium: 2% of the RDI
- Magnesium: 2% of the RDI
- Phosphorus: 10% of the RDI
- Selenium: 22% of the RDI
- Sodium: 2% of the RDI
- Zinc: 4% of the RDI
- Copper: 3% of the RDI
- Vitamin A: 5% of the RDI
- Vitamin E: 7% of the RDI
- Thiamin: 3% of the RDI
- Vitamin B6: 3% of the RDI
- Folate: 5% of the RDI
- Vitamin B12: 9% of the RDI
- Vitamin D: 7% of the RDI
Both egg yolks and egg whites differ in fat and cholesterol levels: the majority of fat in egg yolks is known to have healthy effects on the heart. Further, it contains high levels of vitamins, minerals, and antioxidants making it one of the richest nutrient-dense portions of egg.
Egg Whites vs Yolks: Which Part of the Egg is Healthier?
- For Weight Loss: Egg whites are ideal due to their high protein content and low-calorie count, but including occasional egg yolks can provide essential nutrients.
- For Muscle Building: The entire eggs including the yolk are more effective in muscle mass gains and recovery period than just egg whites.
- For Heart Health: Whole eggs may not be ideal for people who are sensitive to cholesterol, yet one or two eggs can be safe for almost everybody.
- For Overall Health: The yolk comprises of many essential vitamins and nutrients that are good for brain, eye, and body health. Introducing yolks into your diet means that dangerous nutrient ratios are avoided and balanced nutrient ratios are promoted.
Here is a summary comparing the nutritional benefits of egg whites versus whole eggs:
Egg Whites
Benefits
- Excellent source of protein
- Low in calories
- Low in fat
Downsides
- Lack some important vitamins and all essential minerals found in egg
- Lack of healthy fats, fat-soluble vitamins, antioxidants, and choline that are present only in the egg yolk.
Egg Yolks
Benefits
- Good source of vitamins and minerals such as selenium vitamin D, zinc, and vitamin A
- The muskmelon pulp contains nutrients such as lutein and zeaxanthin that are essential in eyesight.
- Have fats, essential for the production of hormones such as cholesterol.
- Rich in choline which is good for brain and liver health.
Downsides
- Has more calories than Egg whites
- Those people contain dietary cholesterol which might require them to avoid taking certain foods.
Recommendations
Whole eggs offer every disease-preventing nutrient most people need and may prevent diseases, reduce inflammation, and protect the eyes.
However, those with elevated cardiovascular risks or with high blood cholesterol are encouraged to reduce their yolk intake to four or at most, two per week. These individuals can also benefit from eggs by consuming more egg whites while at the same time avoiding, or reducing their levels of dietary cholesterol, which is present in the yolks of eggs.
The main difference is rooted in everyone's requirements for nutrient intake. The consumer who chooses to consume eggs based on the management of their weight or cholesterol level is likely to benefit more from the egg whites than from the yellow part hence we recommend that the healthy consumer consumes whole eggs without much restraint.
Conclusion
Regarding the composition and nutritional value, egg whites and yolks can be considered healthy; thus, the issue of which one is better is subjective insofar as one must define one's health objective. However, if you are counting calories or cholesterol, then the egg white could be more suitable for you. However, for a nutrient-dense choice that promotes muscle building, healthy brain functioning, and other important physiological processes, the inclusion of some yolk in the diet is mandatory.
Therefore, instead of focusing on the task of eradicating one part of the egg, try to achieve equilibrium. Balancing the portion of whites and yolks in your meal is helpful since both parts of the eggs are filled with different nutritional benefits. The next time you start frying an egg, do not settle for just cracking the white or yolk of the egg but ponder how both may support or hinder your objectives of developing a healthy lifestyle.
