As you can see, chicken breast is primarily composed of protein with a small amount of fat and virtually no carbohydrates, making it an excellent choice for various dietary needs, from high-protein diets to low-carb eating plans.
Protein Content and Quality
The standout nutritional feature of chicken breast is undoubtedly its protein content. With approximately 31 grams of protein per 3.5-ounce serving, it provides about 62% of the recommended daily intake based on a 2,000-calorie diet.
Complete Protein Source
Chicken breast offers a complete protein profile, meaning it contains all nine essential amino acids that your body cannot produce on its own. These amino acids include:
- Leucine
- Isoleucine
- Valine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Histidine
This complete amino acid profile makes chicken breast particularly valuable for muscle building, repair, and maintenance.
Protein Quality Scores
Protein quality is often measured using scores like the Protein Digestibility Corrected Amino Acid Score (PDCAAS) and the Digestible Indispensable Amino Acid Score (DIAAS). Chicken breast consistently rates high on these scales due to its excellent digestibility and amino acid composition, making it one of the most efficient protein sources available.
Fat Content and Types
Boneless skinless chicken breast is considered a lean meat because of its relatively low fat content compared to other protein sources. A 3.5-ounce serving contains approximately 3.6 grams of total fat.
Fat Composition
The fat in chicken breast is distributed as follows:
- Saturated fat: approximately 1 gram
- Monounsaturated fat: approximately 1.3 grams
- Polyunsaturated fat: approximately 0.8 grams
This fat profile is generally considered heart-healthy, especially when compared to higher-fat protein sources like certain cuts of beef or pork.
Removing the Skin
It’s worth noting that removing the skin significantly reduces the fat content of chicken breast. With the skin on, chicken breast contains nearly three times more fat, jumping from about 3.6 grams to 10-11 grams per 3.5-ounce serving. This dramatic difference explains why boneless skinless chicken breast is often recommended for those watching their fat intake or calorie consumption.
Vitamins and Minerals
Chicken breast contains an impressive array of essential vitamins and minerals that contribute to its nutritional value:
B Vitamins
Chicken breast is particularly rich in B vitamins, including:
- Niacin (Vitamin B3): 56% of the Daily Value (DV)
