Which prefix would be used to indicate a nutrient that is needed in large amounts?

The term that indicates a nutrient required in large amounts is "macronutrient." Macronutrients include carbohydrates, proteins, and fats, which are essential for providing energy and supporting bodily functions. These nutrients are needed in larger quantities compared to other nutrient classes, such as micronutrients, which are vitamins and minerals needed in smaller amounts for various physiological processes.

Understanding the distinction between macronutrients and micronutrients is key. While micronutrients are indeed vital for health, they are needed in much smaller quantities and do not provide energy directly. The term "antinutrient" refers to substances that can interfere with the absorption or utilization of nutrients and is not related to the requirements for nutrient intake. Similarly, "trace nutrient" typically describes minerals needed in minute quantities, which further differentiates them from macronutrients.
