What is the primary role of carbohydrates in the human diet?

• A. To provide energy for the body's functions and activities
• B. To aid in the absorption of vitamins
• C. To serve as a building block for tissues
• D. To maintain electrolyte balance

Answer: (A)

The primary role of carbohydrates in the human diet is to provide energy for the body's functions and activities. Carbohydrates are broken down into glucose, which is then used as a primary source of fuel for the body's cells, tissues, and organs. This is particularly important for high-energy-demand organs such as the brain and muscles during physical activity. Carbohydrates also play a crucial role in physical performance and exercise because they can be rapidly mobilized during intense physical activity. While they do not directly aid in vitamin absorption, serve as building blocks for tissues, or maintain electrolyte balance, their main function clearly centers around energy provision. This is why they are often emphasized in dietary guidelines as a key macronutrient necessary for maintaining overall health and adequate energy levels.
