Which of the following is not classified as a nutrient?

The correct choice is indicated as fruit because it is classified as a food item rather than a nutrient. Nutrients are specific substances that provide nourishment essential for the maintenance of health and development, and they include carbohydrates, proteins, fats (lipids), vitamins, and minerals.

Water is crucial for hydration and various bodily functions, making it an essential nutrient. Lipids are a category of nutrients that include fats and oils, providing energy, supporting cell growth, and aiding in the absorption of certain vitamins. Minerals are inorganic nutrients necessary for processes such as bone formation, fluid balance, and muscle function.

Fruit, while it contains many nutrients, fibers, vitamins, and minerals, is a food category composed of various nutrients and water, rather than being a single nutrient itself. Therefore, it does not fit the definition of a nutrient in a strict sense.
