What is the main function of carbohydrates in the body?

The primary function of carbohydrates in the body is to provide energy. Carbohydrates are one of the three macronutrients, alongside proteins and fats, and are the body's preferred source of fuel, particularly for the brain and during physical activity. When consumed, carbohydrates are broken down into glucose, which is then utilized by cells for energy. This process is essential for maintaining normal bodily functions and supporting various activities, from simple daily tasks to intense exercise.

While carbohydrates play a role in digestion through dietary fiber, which helps regulate bowel movements, their main function is energy provision. Understanding the significance of carbohydrates in energy metabolism helps highlight the importance of including them as part of a balanced diet to support overall health and well-being.
