What is the primary function of carbohydrates in the body?

The primary function of carbohydrates in the body is to provide energy. Carbohydrates are one of the macronutrients that supply fuel for the body's activities. When consumed, carbohydrates are broken down into glucose, which is then used by the body's cells for energy. This energy is essential for daily functions, including physical activities, brain function, and maintaining metabolic processes.

While carbohydrates can also play secondary roles, such as contributing to the structure of cells and aiding in certain metabolic pathways, their main purpose is to serve as a readily available source of energy. This is particularly important during high-intensity exercise and other demanding physical activities, where carbohydrates are often the first line of energy production.
