Energy in nutrition is defined as what?

• A. The ability of the body to perform functions
• B. The amount of feed eaten per day
• C. The color of energy supplements
• D. The taste of feed

Answer: (A)

Energy in nutrition is the body's capacity to do work. It comes from the calories released when nutrients like carbohydrates, fats, and proteins are metabolized and is used to fuel all bodily activities—from basic maintenance of life-sustaining functions to growth, movement, and production. This is why the statement that energy is the body's ability to perform functions is the best description. The amount of feed eaten per day describes intake, not the energy available; the color or taste of feed has no bearing on the energy value.
