- Protein: 6 grams
- Fat: 5 grams
- Cholesterol: 186 mg
- Vitamin A: 6% of the RDA (Recommended Dietary Allowance)
- Vitamin B12: 15% of the RDA

Health Benefits of Eggs:
Cardiovascular Health:
Eggs have been a topic of debate when it comes to cardiovascular health. However, recent studies have shown that moderate egg consumption is not associated with an increased risk of heart disease. In fact, some studies suggest that egg consumption may have a protective effect against heart disease.
One study showed that eating up to one egg per day did not increase the risk of heart disease in diabetic patients. Another dose-response meta-analysis found that moderate egg consumption (up to one egg per day) was not associated with a higher risk of coronary heart disease or stroke.
Weight Management:
If you’re trying to lose weight, consider adding eggs to your diet. Eggs are an excellent source of protein, which can help you feel full and satisfied for longer. One study found that people who ate eggs for breakfast consumed fewer calories for the rest of the day compared to those who had a bagel for breakfast.
Eating eggs may also help you build muscle. The protein in eggs is high-quality and easily digestible, making it an ideal food for muscle building.
Brain Health:
Eggs are an excellent source of choline, a nutrient that is essential for brain health. In fact, choline is so important that the National Academy of Medicine recently established a recommended daily intake. Choline is involved in many functions in the body, including brain development, nerve function, and muscle movement.
One study found that higher choline intake was associated with better cognitive function in both men and women. Another study found that choline intake during pregnancy was associated with improved cognitive function in offspring.
Eye Health:
Eggs are also a source of two antioxidants, lutein, and zeaxanthin, which are important for eye health. These antioxidants accumulate in the retina and may help protect against age-related macular degeneration.
One study found that consuming one egg per day for five weeks increased blood levels of lutein and zeaxanthin by 28-50%.
Effects of Cooking and Proper Storage:
The way that you cook and store eggs can affect their nutrient content. Overcooking eggs can destroy some of the nutrients, so it’s best to cook them to a medium or medium-well temperature. Boiling and poaching are the best methods for preserving nutrients.
It’s also important to store eggs properly to maintain their quality and safety. Keep eggs in their carton in the refrigerator and use them within three to five weeks of purchase.
Varieties and Types of Eggs:
Not all eggs are created equal. Organic, free-range, and pasture-raised eggs may have different nutrient profiles compared to conventionally-raised eggs. For example, pasture-raised eggs may have higher levels of omega-3 fatty acids, which are important for heart health.
The yolk and the white of the egg also have different nutrient profiles. The yolk contains most of the vitamins and minerals, while the white is mostly protein.
Alternative sources of eggs, such as quail or duck eggs, may also have different nutrient profiles compared to chicken eggs.
Disadvantages and Risks of Egg Consumption:
While eggs are generally safe and healthy, some people may have an egg allergy or intolerance. Symptoms can range from mild to severe and may include hives, difficulty breathing, and anaphylaxis.
There is also a risk of salmonella infection from consuming raw or undercooked eggs. To reduce this risk, it’s important to cook eggs thoroughly and handle them properly.
Finally, excessive egg consumption may increase the risk of heart disease in certain populations. However, most people can safely consume up to one egg per day without any negative health effects.
In conclusion, Eggs are a nutritious and versatile food that can provide many health benefits. They are an excellent source of protein, vitamins, and minerals, and may help with weight management, brain health, and eye health. Proper cooking and storage practices can help preserve the nutrient content of eggs, and alternative sources of eggs may offer different nutrient profiles. While egg consumption should be moderated in certain populations, most people can safely enjoy up to one egg per day.
