Which of the following best describes non-fuel nutrients?

The correct answer highlights that non-fuel nutrients include vitamins, minerals, and water. These components are classified as essential nutrients that do not provide energy or calories but are vital for maintaining bodily functions, promoting good health, and supporting overall well-being.

Vitamins are organic compounds necessary for various metabolic processes, while minerals are inorganic elements that play critical roles in nerve function, muscle contraction, and overall cellular health. Water, the most crucial nutrient, is vital for hydration, temperature regulation, and nutrient transport in the body. Together, these non-fuel nutrients help to prevent deficiencies and support physiological processes but do not directly contribute to energy production or caloric intake.
