Which nutrient is essential for maintaining body tissue and supporting growth?

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

Answer: (B)

Proteins are the nutrient essential for maintaining body tissue and supporting growth. They supply amino acids, the building blocks for all tissues and for important proteins like enzymes, hormones, and antibodies. Essential amino acids must come from the diet, making adequate protein intake crucial for tissue repair, wound healing, and growth during childhood, pregnancy, and recovery from illness. Carbohydrates mainly provide energy; fats provide dense energy and support cell membranes and fat-soluble vitamin absorption; vitamins act as cofactors in many metabolic processes. Without enough protein, tissue breakdown occurs, healing slows, and growth can be impaired.
