Name the main nutrients required in large amounts by the body.

• A. Vitamins, minerals, and water
• B. Carbohydrates, fats, and vitamins
• C. Carbohydrates, proteins, and fats
• D. Fiber, minerals, and water

Answer: (C)

Nutrients needed in the largest amounts are the macronutrients, which provide the energy and building blocks the body uses daily. The three main macronutrients are carbohydrates, proteins, and fats. Carbohydrates and fats supply energy for body activities and metabolism, while proteins supply amino acids for growth, tissue repair, and making enzymes and hormones. Vitamins and minerals are essential too, but they’re required in much smaller amounts, so they’re called micronutrients. Fibre isn’t digested for energy, and water is essential for life but isn’t an energy-providing nutrient. That’s why carbohydrates, proteins, and fats are the main nutrients needed in large amounts.
