Which nutrient is most important for growth and repair of body tissues?

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

Answer: (C)

Proteins are the building blocks the body uses for growth and tissue repair. When you grow or heal, your body needs amino acids to synthesize new proteins that form muscles, skin, bones, and connective tissue. Proteins also supply the enzymes and antibodies that support metabolism, healing, and immune function. Carbohydrates and fats mainly provide energy, while vitamins support many metabolic processes but don’t supply the actual materials for constructing new tissues. Without enough protein, growth slows and healing can be delayed, even if energy and vitamins are adequate. That makes protein the essential nutrient for growth and tissue repair.
