Which of the following is NOT among the six essential nutrients?

Explanation:
The concept here is identifying substances that must come from the diet to support health and growth. The six essential nutrients are water, minerals, vitamins, carbohydrates, proteins, and fats. Oxygen, while absolutely necessary for life because it enables energy production in cells, is not consumed as part of a diet and is obtained from the air. It isn’t counted among the essential nutrients because it isn’t a dietary nutrient providing energy or building blocks. Water hydrates and enables chemical reactions; minerals support structure and enzyme functions; vitamins help metabolism; carbohydrates, fats, and proteins supply energy and the components needed for growth and repair.
