Which set of nutrients provides calories and energy?

Which set of nutrients provides calories and energy?

• A. Vitamins, Minerals, and Water
• B. Carbs, Proteins, and Fats
• C. Fiber and Water
• D. Alcohol and Carbs

Answer: (B)

Calories come from macronutrients that the body converts into usable energy. Carbohydrates, proteins, and fats are energy-yielding nutrients, providing calories when metabolized (about 4 kcal per gram for carbs and protein, 9 kcal per gram for fats). Fiber and water don’t supply calories because they aren’t digested for energy, and vitamins/minerals don’t provide energy either. Alcohol does provide energy (about 7 kcal per gram) but isn’t considered a nutrient. Therefore, the set that provides calories and energy is carbohydrates, proteins, and fats.
