What is the primary function of carbohydrates in the diet?

The primary function of carbohydrates in the diet is to provide energy. Carbohydrates are one of the three macronutrients, along with protein and fat, and they are the body's preferred source of fuel. When consumed, carbohydrates are broken down into glucose, which is used by cells for immediate energy or stored as glycogen in the liver and muscles for later use. This glucose is crucial for various bodily functions, including maintaining blood sugar levels and supplying energy for physical activities and metabolic processes.

While carbohydrates can play a supporting role in brain function and may influence aspects of immune function indirectly, their most significant contribution lies in energy provision. This is particularly important for athletes and individuals engaging in regular physical activity, as carbohydrates are essential for sustaining performance and recovery.
