Which macronutrient is primarily associated with tissue repair and growth?

• A. Carbohydrates
• B. Fats
• C. Proteins
• D. Vitamins

Answer: (C)

Proteins are the building blocks used for tissue repair and growth. They are made of amino acids, the raw materials your body uses to rebuild damaged tissue, create new tissue during growth, and form essential structures such as collagen, enzymes, antibodies, and hormones. During healing or growth, the body ramps up protein synthesis to replace cells and build new tissue. Carbohydrates and fats primarily provide energy to support these processes, while vitamins support metabolism and enzyme function but don’t supply the main building blocks. So, the macronutrient most closely linked to tissue repair and growth is protein.
