Which of the following best defines "nutrients"?

The definition of "nutrients" pertains to the essential substances found in food that our bodies require for a variety of vital functions, including growth, repair of tissues, and the generation of energy. Nutrients play a crucial role in maintaining overall health, as they include carbohydrates, proteins, fats, vitamins, and minerals. Each of these components contributes to different biological processes necessary for the body's functioning.

In contrast, the other options focus on more limited aspects, such as flavor enhancement, which does not encompass the broader spectrum of essential functions that nutrients provide. Artificial supplements are a form of nutrient but they are not the natural sources that the body thrives on. Additionally, the mention of vitamins only refers to a specific category of nutrients and neglects other vital ones required for a balanced diet. The chosen answer effectively encapsulates the comprehensive role of all types of nutrients in supporting health and functioning in living organisms.
