The primary function of carbohydrates is to serve as a major source of energy for the body. They are broken down into glucose, which is utilized by cells and tissues to perform various functions. Carbohydrates are crucial for maintaining optimal energy levels, particularly for high-intensity activities. They are categorized into simple carbohydrates, like sugars, and complex carbohydrates, such as starches and fibers. Besides providing energy, dietary carbohydrates are essential for proper digestive function and can contribute to feelings of fullness. A balanced intake of carbohydrates supports overall health and physical performance.
