Which substances are included in the category of essential nutrients?

Essential nutrients are those that the body cannot synthesize on its own and must be obtained from the diet. This category includes a wide variety of substances that play critical roles in maintaining health and supporting various bodily functions.

Proteins provide amino acids, which are vital for growth, repair, and the maintenance of tissues. Minerals contribute to bone health, muscle function, and are involved in many enzymatic processes. Carbohydrates are the body’s primary energy source, and fats are important for energy, hormone production, and cellular structure.

Vitamins are organic compounds that are required for metabolic processes, while water is crucial for hydration, temperature regulation, and transportation of nutrients. Since all of these substances are necessary for overall health and cannot be adequately produced by the body, they collectively fit under the classification of essential nutrients. This comprehensive inclusivity explains why the correct answer encompasses all the listed substances.
