Which of the following lists contains the six essential nutrients?

• A. Proteins, Fats, Carbohydrates, Vitamins, Minerals, Water
• B. Vitamins, Minerals, Fiber, Water, Sugar, Salt
• C. Proteins, Fats, Carbohydrates, Fiber, Water, Alcohol
• D. Proteins, Fats, Carbohydrates, Vitamins, Minerals, Oxygen

Answer: (A)

The main idea being tested is recognizing the six essential nutrient categories that the body must obtain from food: the three macronutrients (proteins, fats, carbohydrates) for energy and structure, the micronutrients (vitamins, minerals) for metabolism and bodily functions, and water for hydration and chemical processes. The set that includes Proteins, Fats, Carbohydrates, Vitamins, Minerals, and Water represents these six fundamental categories, making it the correct choice.

Why the others don’t fit: fiber is beneficial for digestion but not considered an essential nutrient in the strict sense; sugar and salt aren’t classified as essential nutrients themselves (sugar isn’t required by the body, and while minerals like sodium are essential, “salt” as a term isn’t listing the mineral category); alcohol isn’t an essential nutrient and provides no required nutrient function; oxygen is essential for life but is not consumed as a dietary nutrient.
