What are macronutrients?

What are macronutrients?

• A. Water and electrolytes
• B. Minerals
• C. Carbohydrates, fats, proteins
• D. Vitamins

Answer: (C)

Macronutrients are the nutrients required in large amounts by the body because they provide energy and the building blocks for growth and repair. The three macronutrients are carbohydrates, fats, and proteins. They differ from micronutrients, which include vitamins and minerals and are needed in smaller amounts and do not supply energy. Water is essential for life and metabolism, but it is not classified with the energy-yielding macronutrients. Carbohydrates and proteins supply about 4 kcal per gram, while fats provide about 9 kcal per gram, with proteins also playing important roles in tissue repair and enzyme production.
