3. Protein Content
Beef: Known for its high-quality protein profile, beef contains all the essential amino acids required for muscle growth and repair.
Tuna: A lean fish, tuna is also a complete protein source, making it an excellent choice for those looking to increase their protein intake without adding excess fat.
4. Fat Content
Beef: The fat content in beef varies depending on the cut, but it can range from lean to high-fat. Saturated fats in beef are often a point of concern.
