What is the primary function of carbohydrates in the body?

Carbohydrates play a vital role in the body primarily because they are the body's main source of energy. When consumed, carbohydrates are broken down into glucose, which is then utilized by the cells for fuel. This energy is crucial for the functioning of all body systems, including the brain, which relies almost exclusively on glucose for its energy needs.

In addition to providing immediate energy, carbohydrates also assist in maintaining blood sugar levels during periods of fasting or intense physical activity. In this way, the body can keep energy levels stable, ensuring that various functions can occur without interruption.

While carbohydrates are crucial for energy, they do not play a primary role in building muscle mass, supporting immune function, or promoting hydration in the same direct manner. These processes involve proteins, vitamins, minerals, and water, respectively, but carbohydrates remain essential for energy, making them the primary source for fueling bodily functions.
