What is the primary function of carbohydrates in the body?

Carbohydrates play a crucial role in the body primarily by providing energy. When carbohydrates are consumed, they are broken down into glucose, which is then used as the primary source of energy for various bodily functions. This includes powering muscles during physical activities and serving as fuel for the brain, which depends heavily on glucose to carry out its functions efficiently.

While carbohydrates are not primarily involved in building tissues, facilitating digestion, or regulating hormones, they do contribute indirectly to these processes. For instance, complex carbohydrates found in fiber can aid in digestion by promoting gut health, but their essential function remains energy provision. Understanding this fundamental role of carbohydrates helps illustrate why they are considered a vital macronutrient in a balanced diet.
