Which of these nutrients does NOT provide energy?

Vitamins are essential nutrients that play vital roles in various physical processes, including metabolism, immunity, and overall health. However, they do not provide energy in the form of calories. Instead, vitamins assist in the biochemical reactions that release energy from macronutrients such as carbohydrates, proteins, and fats.

Carbohydrates, proteins, and fats are all macronutrients that provide energy. Carbohydrates are the body's primary energy source, proteins can be used for energy when necessary, and fats provide the highest energy yield per gram compared to the other macronutrients. While these nutrients are critical for energy production and bodily functions, vitamins serve a supportive role rather than a direct energy-supplying function.
