Which nutrient provides the body with no protein, vitamins, or minerals?

The nutrient that provides the body with no protein, vitamins, or minerals is sugar. Sugar is primarily composed of simple carbohydrates and serves as a quick source of energy for the body. While it can be an important source of energy, it lacks the essential nutrients that other macronutrients, such as proteins and fats, contain.

Fats, in contrast, are rich in energy and essential fatty acids, and they also play a role in the absorption of fat-soluble vitamins. Proteins provide amino acids, which are critical for building and repairing tissues, as well as various vitamins and minerals depending on the protein source. Vitamins are organic compounds that are crucial for various metabolic processes and help in maintaining health, each serving specific functions in the body.

Therefore, sugar stands out as a nutrient that offers calories but does not contribute any significant amounts of protein, vitamins, or minerals, confirming that it is the correct answer.
