Which of the following is NOT considered a basic nutrient?

In the context of nutrition, basic nutrients are essential substances required for the proper functioning of the body. These include proteins, water, vitamins, and minerals, as they contribute to growth, energy, and overall health.

Alcohol, while it does provide calories, is not classified as a nutrient because it does not fulfill the body's physiological needs in the same way that the other options do. Instead of providing essential functions, alcohol can actually have harmful effects, including toxicity and negative impacts on health. Thus, it does not fit the criteria of a basic nutrient, which must be necessary and beneficial for the body’s well-being.
