The protein power of 100g of cooked chicken breast
For many health-conscious individuals, fitness enthusiasts, and home cooks, understanding the nutritional value of their food is paramount. Chicken breast is a staple for many, prized for its high protein and low fat content. The question of how much protein is 100 g of cooked chicken breast is a common one, and the answer highlights why it's such an efficient protein source.
A standard 100-gram (3.5-ounce) serving of cooked, skinless chicken breast provides approximately 31 grams of protein. This figure is higher than that of raw chicken, where the same 100g would contain about 22-24 grams of protein, because cooking removes moisture, concentrating the nutrients. This is an important distinction to remember when tracking macros for meal planning. This high protein density is why chicken breast is often recommended for muscle building, weight loss, and general dietary health.
Raw vs. cooked: The concentration effect
When we cook chicken, we are essentially altering its weight and volume. The moisture content is significantly reduced through processes like roasting, grilling, or boiling. For example, a 100g piece of raw chicken might shrink to around 75-80g after cooking. While the total amount of protein in that specific piece of chicken remains the same, its concentration per gram increases. Therefore, 100g of cooked chicken is more protein-dense than 100g of raw chicken.
- Raw chicken: A 100g serving of raw, boneless, skinless chicken breast contains approximately 22-24g of protein.
- Cooked chicken: A 100g serving of cooked, boneless, skinless chicken breast contains approximately 31g of protein.
This difference means that measuring your protein source after it is cooked provides a more accurate representation of your intake. This is particularly relevant for those on strict dietary plans, such as competitive bodybuilders or individuals tracking macros closely.
Nutritional comparison: Chicken breast vs. other protein sources
While chicken breast is a powerhouse of protein, it's useful to see how it stacks up against other common options. This comparison helps in dietary planning and ensures variety in nutrient intake.
Protein content per 100g cooked
| Protein Source (per 100g cooked) | Protein (g) | Calories (approx.) | Notes |
|---|---|---|---|
| Chicken Breast (skinless) | ~31g | ~165 | Low fat, high protein |
| Ground Beef (90/10) | ~26g | ~250 | Higher fat and calories |
| Ground Turkey (93/7) | ~29g | ~180 | Good alternative to beef |
| Salmon | ~25g | ~200 | Rich in omega-3 fatty acids |
| Tofu (firm) | ~17g | ~145 | Excellent plant-based option |
Chicken breast offers a superior protein-to-calorie ratio compared to many other protein sources, especially lean cuts of meat. This makes it an ideal choice for weight management, where a high protein intake can promote satiety and preserve muscle mass while on a lower calorie diet.
Factors influencing protein levels
The protein content isn't a fixed number and can be influenced by several factors beyond just the cooking process:
- Presence of skin: Leaving the skin on chicken breast adds fat and calories but does not significantly change the protein content of the meat itself. A skinless breast remains the leaner choice.
- Chicken breed and diet: Studies have shown that different chicken genotypes and diets can influence the protein and fat composition of the meat. Native or local breeds may sometimes have a slightly higher protein percentage compared to standard commercial broilers.
- Storage and processing: The way meat is stored and processed can affect its nutritional value. For instance, processes like freezing and thawing can impact moisture retention and protein solubility.
The versatile and beneficial nature of chicken breast
Beyond its high protein content, chicken breast offers several other health benefits. It's a complete protein, meaning it contains all nine essential amino acids required by the body. These amino acids are crucial for muscle repair, growth, and overall bodily function. Chicken breast is also a good source of important vitamins and minerals, including B vitamins (such as niacin and B6), selenium, and phosphorus.
The versatility of chicken breast makes it a kitchen staple. It can be baked, grilled, boiled, or sautéed, and its mild flavor profile means it pairs well with a variety of seasonings and dishes. For those looking to maximize nutritional benefits, cooking methods that minimize added fats, like grilling or baking, are recommended.

Conclusion
In summary, 100 grams of cooked, skinless chicken breast contains an impressive ~31 grams of lean, high-quality protein. This makes it a fantastic and efficient choice for those focusing on muscle gain, weight loss, or simply maintaining a healthy, balanced diet. The concentration of protein increases during the cooking process due to water loss, a key point to remember for accurate nutritional tracking. By understanding this, you can better plan your meals and take full advantage of this versatile protein source.
