What Is the Role of Carbohydrates?

Carbohydrates are the body's primary source of energy, fueling daily activities and essential bodily functions. When consumed, carbohydrates are broken down into glucose, which is used by cells for immediate energy or stored for later use. Carbohydrates are classified into simple carbs (found in sugar, fruits, and processed foods) and complex carbs (found in whole grains, vegetables, and legumes). Complex carbohydrates are healthier because they provide sustained energy, fiber, and essential nutrients. In addition to energy, carbohydrates play a role in brain function, as glucose is the brain’s preferred energy source. A balanced intake of carbohydrates helps regulate blood sugar levels and prevents energy crashes. However, excessive consumption of refined carbohydrates, such as white bread and sugary snacks, can lead to weight gain and an increased risk of diabetes. Choosing whole, fiber-rich carbs promotes overall health and sustained energy levels.
