The primary function of carbohydrates in our diet is to serve as the body’s main source of energy. They are broken down into glucose, which fuels our cells, particularly during physical activity. Carbohydrates are vital for brain function, as the brain relies on glucose for optimal performance. They also play a role in supporting the body's muscle glycogen stores, which are essential for endurance and high-intensity exercise. Consuming an adequate amount of carbohydrates is crucial for maintaining energy levels, promoting recovery, and ensuring overall health.
