Eggs vs. Chicken: Which Is the Best Protein Source? (Science-Backed Comparison)

Eggs vs. Chicken: Which Is the Best Protein Source?







Protein is a crucial nutrient for muscle growth, weight management, and overall health. While both eggs and chicken are excellent protein sources, many people wonder which one is better.

Eggs are known for their complete amino acid profile and nutrient density, while chicken is a lean meat packed with high-quality protein. But which one should you choose for muscle building, weight loss, or general health?

In this article, we’ll compare eggs vs. chicken in terms of protein content, nutritional benefits, and suitability for different dietary goals.


Nutritional Comparison: Eggs vs. Chicken

To determine the better protein source, let’s compare 100 grams of eggs vs. 100 grams of chicken breast in terms of protein and other essential nutrients.

Nutrient Eggs (100g) Chicken Breast (100g)
Calories 143 kcal 165 kcal
Protein 13g 31g
Fats 10g 3.6g
Carbohydrates 1.1g 0g
Cholesterol 373mg 85mg
Iron 1.75mg 0.7mg
Vitamin B12 1.1mcg 0.3mcg

While chicken breast has more protein per 100g, eggs offer a better range of vitamins and minerals.


Protein Quality: Which One is Superior?

Eggs: A Complete and Bioavailable Protein

  • Eggs contain all nine essential amino acids, making them a complete protein.
  • They have a biological value (BV) of 100, meaning the body absorbs and utilizes egg protein very efficiently.
  • Egg yolks are rich in choline, healthy fats, and essential vitamins.

Chicken: Lean and High in Protein

  • Chicken, particularly chicken breast, is one of the leanest and highest protein sources.
  • With a BV of 79, chicken is highly digestible but slightly lower than eggs in bioavailability.
  • Low in fat and zero carbs, making it ideal for muscle growth and weight loss.

Verdict: If you need maximum protein per serving, chicken is the winner. But if you want a more balanced nutrient profile, eggs are better.

  • Chicken is lower in cholesterol, making it a better choice for those with cholesterol concerns.
  • Best choice: Chicken for those with heart conditions, eggs for nutritional benefits.

4. Overall Nutrient Density

  • Eggs contain Vitamin B12, Choline, Iron, and Omega-3s.
  • Chicken is rich in Niacin, Selenium, and Lean Protein.
  • Best choice: Eggs for more micronutrients, chicken for pure protein.
