What is the role of carbohydrates in the body?

Carbohydrates play a critical role in the body primarily as a source of energy. When consumed, they are broken down into glucose, which is used by the body's cells to fuel various functions, from muscle contraction to brain activity. This process makes carbohydrates the body's preferred energy source, especially during high-intensity exercise and physical activity.

Furthermore, carbohydrates are stored in the body in the form of glycogen, primarily in the liver and muscles. This stored energy can be quickly mobilized when needed, such as during periods of fasting or increased physical activity, ensuring that the body has a readily available energy source.

While proteins are important for building and repairing tissues and fats provide insulation and energy storage, carbohydrates specifically serve the function of providing quick and efficient energy for bodily processes, which underscores why storing energy is their main role.
