Beef and veal are excellent sources of high-quality protein, providing essential amino acids needed for muscle growth and repair. They are also rich in important nutrients such as iron, zinc, and B vitamins like B12, which is crucial for energy production and brain health. A 3-ounce serving of cooked beef typically contains around 250 calories, making it a nutrient-dense option for many diets. However, it's important to choose lean cuts to minimize saturated fat intake.
