The option indicating proteins as the predominant type of food that helps in building muscle mass is grounded in the fundamental role that protein plays in muscle synthesis. Proteins are composed of amino acids, which are the building blocks of muscle. When engaging in strength training or any form of resistance exercise, the body undergoes a process of muscle repair and growth that relies heavily on adequate protein intake.

Consuming sufficient protein helps to stimulate muscle protein synthesis, the process through which new muscle tissue is formed. This is vital for those looking to increase their muscle mass, as a balanced diet rich in protein can support recovery and enhance muscle growth after workouts.

While fruits, whole grains, and dairy products can all contribute to overall nutrition, they serve different roles. Fruits provide important vitamins and antioxidants, whole grains supply carbohydrates for energy, and dairy products can contain protein as well as calcium, but they do not focus exclusively on muscle building like proteins do. Therefore, proteins stand out as the primary food group necessary for effectively building and repairing muscle tissue.
