Eggs are highly nutritious and offer a wide range of health benefits. Here’s a detailed breakdown of the nutritional value of a typical large egg (approximately 50 grams):
Macronutrients:
- Calories: About 70-78 kcal
- Protein: Approximately 6-7 grams
- Fat: Around 5 grams
- Saturated Fat: 1.6 grams
- Monounsaturated Fat: 2 grams
- Polyunsaturated Fat: 1 gram
- Carbohydrates: Less than 1 gram
- Cholesterol: Around 186 mg
Micronutrients:
- Vitamins:
- Vitamin A: 270 IU (5% of the Daily Value, DV)
- Vitamin D: 41 IU (10% DV)
- Vitamin E: 0.5 mg (3% DV)
- Vitamin B2 (Riboflavin): 0.25 mg (15% DV)
- Vitamin B12: 0.6 µg (10% DV)
- Folate: 24 µg (6% DV)
- Vitamin B6: 0.1 mg (5% DV)
- Minerals:
- Iron: 0.9 mg (5% DV)
- Calcium: 28 mg (2% DV)
- Potassium: 69 mg (2% DV)
- Phosphorus: 99 mg (10% DV)
- Zinc: 0.6 mg (4% DV)
- Selenium: 15.4 µg (22% DV)
Additional Nutrients:
- Choline: About 147 mg (27% DV) – important for brain health and development.
- Lutein and Zeaxanthin: Antioxidants beneficial for eye health.
Health Benefits:
- High-Quality Protein: Eggs provide all nine essential amino acids, making them a complete protein source.
- Weight Management: The protein content in eggs can help with satiety and reduce overall calorie intake.
- Brain Health: Choline is crucial for neurotransmitter synthesis and brain function.
- Eye Health: Lutein and zeaxanthin help protect against age-related macular degeneration and cataracts.
- Heart Health: While eggs contain cholesterol, recent research suggests that for most people, dietary cholesterol does not significantly impact blood cholesterol levels.
Considerations:
- Dietary Cholesterol: Individuals with certain health conditions, like hypercholesterolemia, may need to moderate their egg intake.
- Allergies: Some people may be allergic to eggs, particularly children, although many outgrow this allergy.
In summary, eggs are nutrient-dense and provide a substantial amount of vitamins, minerals, and high-quality protein, making them an excellent addition to a balanced diet.

Eggs from hens raised in more natural, open environments (often referred to as free-range, pasture-raised, or organic eggs) can have a slightly different nutritional profile compared to conventional eggs. These differences primarily stem from the hens’ diet and living conditions, which can influence the nutritional content of the eggs they produce.
Nutritional Value of Free-Range or Pasture-Raised Eggs:
Macronutrients:
- Calories: About 70-78 kcal (similar to conventional eggs)
- Protein: Approximately 6-7 grams (similar to conventional eggs)
- Fat: Around 5 grams
- Saturated Fat: 1.6 grams
- Monounsaturated Fat: 2 grams
- Polyunsaturated Fat: 1 gram
- Carbohydrates: Less than 1 gram
- Cholesterol: Around 186 mg
Micronutrients:
While the basic micronutrient profile is similar to conventional eggs, certain nutrients may be present in higher amounts:
- Omega-3 Fatty Acids: Pasture-raised eggs can contain up to twice the amount of omega-3 fatty acids compared to conventional eggs. This is due to the hens’ diet, which may include more omega-3-rich foods like flaxseeds and grasses.
- Vitamin A: Levels can be higher due to a diet richer in carotenoids.
- Vitamin E: Also tends to be higher in pasture-raised eggs.
- Vitamin D: Levels can be up to four times higher in pasture-raised eggs, as hens exposed to sunlight produce more vitamin D.
Additional Nutrients:
- Choline: Approximately 147 mg (27% DV) – similar to conventional eggs.
- Lutein and Zeaxanthin: Often found in higher concentrations due to the hens’ natural diet.
Health Benefits:
- Higher Omega-3 Fatty Acids: Beneficial for heart health, reducing inflammation, and supporting brain function.
- Increased Vitamin D: Important for bone health and immune function.
- Better Fatty Acid Profile: A higher ratio of omega-3 to omega-6 fatty acids, which is favorable for reducing the risk of chronic diseases.
Considerations:
- Cost: Free-range and pasture-raised eggs are often more expensive than conventional eggs.
- Availability: They may not be as widely available as conventional eggs in some areas.
- Animal Welfare: Hens in these systems typically have better welfare conditions, which can be an important consideration for many consumers.
In summary, free-range or pasture-raised eggs can offer enhanced nutritional benefits, particularly with higher levels of omega-3 fatty acids, vitamins A, D, and E. These eggs come from hens that have a more varied diet and greater exposure to sunlight, which contributes to their enriched nutritional profile.
