What role do carbohydrates play in nutrition?

They build muscle tissue and repair cells

They provide the primary source of energy for the body

Carbohydrates play a crucial role in nutrition primarily by serving as the body's main source of energy. When consumed, carbohydrates are broken down into glucose, which is a simple sugar used by cells for fuel. This process is vital because energy is required for all bodily functions, including physical activity, brain function, and metabolic processes. Specifically, the brain relies heavily on glucose; it cannot utilize fat directly for energy, making carbohydrate intake particularly important for cognitive function and overall energy levels.

While other nutrients like proteins and fats contribute to energy as well, carbohydrates are the most efficient source, especially during high-intensity exercise. They also help in the regulation of protein and fat metabolism. Understanding the primary role of carbohydrates as energy providers is key for managing dietary choices and optimizing nutrition for health and performance.
