Calories on a nutrition label indicate energy per serving; which statement is true about them?

• A. Calories per serving indicate protein quality
• B. Calories per serving indicate energy per serving
• C. Calories per serving indicate vitamin content
• D. Calories per serving indicate energy per serving

Answer: (D)

Calories on a nutrition label represent the energy you would obtain from one serving. They come from the energy released by the macronutrients in the food (fat, carbohydrate, and protein) and are shown as kilocalories. This measurement does not reflect protein quality or vitamin content, which are determined by amino acid balance and vitamin amounts, respectively. So the statement that calories indicate energy per serving is the one that aligns with what these labels actually show.
