What is the primary function of carbohydrates in the body?

The primary function of carbohydrates in the body is to provide energy for physical activity and metabolic functions. Carbohydrates are broken down into glucose, which serves as the main energy source for all cells, particularly during high-intensity exercise. This glucose is essential for fueling the brain, red blood cells, and muscles, making it vital for both ordinary daily activities and athletic performance.

While muscle growth and repair, regulation of body temperature, and enhancement of bone density are important physiological functions, they are not primarily associated with carbohydrates. Protein plays a significant role in muscle repair and growth, fats can assist in maintaining body temperature and hormone production, and minerals along with other nutrients are crucial for bone health. Understanding the major role of carbohydrates helps in structuring diets effectively for various energy needs and activities.
