Meat and poultry are rich sources of protein, essential vitamins, and minerals. Lean meats like chicken, turkey, and beef provide high-quality protein, which is crucial for muscle building and repair. Additionally, they contain important nutrients such as iron, zinc, and B vitamins. A 3-ounce serving of cooked chicken breast contains approximately 25 grams of protein and only a few grams of fat, making it a healthy choice for a balanced diet.
