What are two primary functions of carbohydrates?

Carbohydrates serve two primary functions in the body: providing energy and supplying dietary fiber. As a vital macronutrient, carbohydrates are the body's main source of energy. They are broken down into glucose, which is utilized by cells for immediate energy needs or stored in the liver and muscles as glycogen for later use.

Additionally, carbohydrates are important for digestive health due to their fiber content. Dietary fiber, derived from plant-based carbohydrates, aids in digestion, helps regulate blood sugar levels, and contributes to feelings of fullness. This dual role highlights the significance of carbohydrates in maintaining energy levels and supporting overall gastrointestinal health, thus affirming the correctness of identifying providing energy and fiber as their primary functions.
