The macronutrient profile—protein, fat, and carbohydrates—highlights its role as a high-protein, low-fat food source. A standard 120g cooked serving provides significant protein with minimal fat and no carbohydrates.
Detailed Macronutrient Analysis
- Protein: At approximately 36 grams per 120g serving, chicken breast is an excellent source of complete protein.
