What is the primary reason for including protein in a diet?

• A. To provide quick energy
• B. To support muscle repair and growth
• C. To increase fat storage
• D. To promote dental health

Answer: (B)

Including protein in a diet primarily supports muscle repair and growth due to its critical role as a macronutrient composed of amino acids, which are the building blocks of muscle tissue. When engaging in physical activities, particularly resistance training, muscle fibers undergo stress and are likely to incur microscopic tears. The presence of protein in the diet aids in repairing these fibers, leading to muscle adaptations that include growth (hypertrophy) and increased strength. Moreover, protein not only contributes to the maintenance and development of muscle but also has various functions in the body, including enzyme production, hormone regulation, and immune function. Consuming an adequate amount of protein is vital, especially for individuals who are active or those looking to improve their physical fitness, as it provides the necessary tools for recovery and performance enhancement. This makes protein essential for anyone aiming to maintain a healthy and functional body composition.
