Which nutrient is important for wound healing?

• A. Carbohydrates
• B. Fats
• C. Vitamin C
• D. Protein

Answer: (D)

Protein is essential for wound healing because it provides the amino acids that build new tissue and collagen, the main structural protein that gives strength to repaired tissue. When a wound occurs, cells like fibroblasts use these amino acids to synthesize collagen and form new tissue to close the wound and restore integrity. Without enough protein, the body cannot efficiently repair tissue, and healing slows or stalls. Adequate protein also supports immune function, which helps prevent infection during healing. Other nutrients play supportive roles—carbohydrates and fats supply energy, and vitamin C supports collagen synthesis—but protein is the primary nutrient driving tissue repair and wound strength.
