A necessary substance that provides energy, promotes growth and health, and helps regulate metabolism is called what?

• A. Nutrient
• B. Vitamin
• C. Mineral
• D. Calorie

Answer: (A)

Nutrients are the substances in food that the body needs to function, providing energy, supporting growth and health, and helping regulate metabolism. They include energy-yielding nutrients like carbohydrates, fats, and proteins, as well as vitamins and minerals that support metabolic processes. A calorie is just a unit of energy, not a substance, so it isn’t the right term. Vitamins and minerals are types of nutrients, but the broad category that covers all these essential substances is nutrient. In geriatric care, ensuring adequate nutrient intake supports strength, healing, and overall health.
