Which term best describes nutrients needed in large amounts by the body?

The term that best describes nutrients needed in large amounts by the body is macro-nutrients. Macro-nutrients are the primary nutrients that provide energy and support physiological functions, and they include carbohydrates, proteins, and fats. These nutrients are required in relatively large quantities compared to trace nutrients or micro-nutrients, which the body needs in smaller amounts.

Understanding macro-nutrients is essential because they play crucial roles in maintaining health and supporting bodily functions. For instance, carbohydrates serve as the primary energy source, proteins are vital for growth and repair of tissues, and fats are important for energy storage and cell function. Ensuring an adequate intake of these macro-nutrients is key to achieving a balanced diet and overall well-being.
