Which of the following is NOT a macronutrient?

Macronutrients are the nutrients that provide energy and are required in large amounts in the diet. They include carbohydrates, fats, and proteins. Each of these macronutrients serves essential functions in the body, such as providing energy, supporting cell structure, and facilitating various biochemical processes.

Vitamins, on the other hand, are classified as micronutrients, not macronutrients. They are required in smaller quantities and play crucial roles in various bodily functions, including supporting metabolism, immune function, and cell repair. Unlike macronutrients, vitamins do not provide energy directly.

Therefore, identifying vitamins as the option that is not a macronutrient aligns with the definitions and roles of these nutritional components.
