What is the primary function of carbohydrates in the body?

The primary function of carbohydrates in the body is to provide energy. Carbohydrates are the body's main source of fuel, particularly for the brain and during physical activity. When consumed, carbohydrates are broken down into glucose, which can be used immediately for energy or stored as glycogen in the liver and muscles for later use. This quick and efficient conversion to energy makes carbohydrates crucial for maintaining energy levels throughout the day.

While carbohydrates can have other roles, such as assisting in digestion through dietary fiber, their main purpose is energy provision. Other nutrients perform the tasks of hormone regulation and muscle building, but carbohydrates are specifically designed to supply energy to the body's cells swiftly and effectively.
