Carbohydrates serve as one of the body's primary sources of energy. They are broken down into glucose, which is used by our cells to fuel various bodily functions, including physical activity and brain function. Carbohydrates are classified into three main types: sugars, starches, and fiber. While sugars provide immediate energy, starches serve as a more sustained source, and fiber contributes to digestive health. In addition to energy provision, carbohydrates can play roles in cellular structure and signaling. A balanced diet with an appropriate amount of carbohydrates is crucial for overall health and wellness.
