What is one role of carbohydrates in the diet?

Build muscles
Support digestion
Provide energy
Repair tissues

The correct answer is: Provide energy

Carbohydrates play a crucial role in providing energy, which is vital for the proper functioning of the body. When consumed, carbohydrates are broken down into glucose, the primary source of fuel for the body's cells. This energy is essential not only for physical activities but also for the overall metabolic processes that keep the body functioning properly. For example, during exercise, carbohydrates are often the first source of energy that the body utilizes. They are particularly important for high-intensity workouts, where rapid energy release is needed. Additionally, the brain relies heavily on glucose, making carbohydrates important for cognitive functions and mental clarity. While carbohydrates do contribute to other functions, such as supporting digestion through certain types of fiber, their primary role is to provide the energy necessary for all physiological functions and activities.
