How do carbohydrates primarily function in the body?

Carbohydrates primarily serve as the main energy source for the body. When consumed, carbohydrates are broken down into glucose, which is then used by the body’s cells to produce energy. This energy is crucial for various physical activities, as well as for supporting bodily functions such as metabolism, digestion, and cognitive processes.

Glucose can be readily converted into energy through cellular respiration, making it an efficient source of fuel compared to other macronutrients. The body also stores excess glucose as glycogen in the liver and muscles, which can be utilized later when energy demands increase, such as during exercise or periods of fasting.

While carbohydrates play important roles in other areas, such as contributing to dietary fiber, which is essential for digestive health, their primary function remains centered around energy provision.
