Which of the following describes nutrients?

The correct choice describes nutrients as substances found in food that are required for energy and body maintenance. This definition encompasses the various roles nutrients play in the body, including providing energy for daily activities, supporting growth and development, and facilitating essential bodily functions.

Nutrients are divided into different categories, such as carbohydrates, proteins, fats, vitamins, and minerals, each contributing to the overall health and functioning of the body. Without these nutrients, the body would struggle to maintain its processes and overall health, highlighting their importance beyond just energy provision.

In contrast, the other options present narrower or inaccurate descriptions. Some focus only on aspects like energy provision or physical development, neglecting other critical roles that nutrients fulfill in maintaining overall health and well-being. Others incorrectly emphasize cooking ingredients without recognizing their physiological importance. The broad and essential nature of nutrients makes the first option the most accurate description.
