Carbohydrates are one of the three main macronutrients, alongside proteins and fats. They are organic compounds made up of carbon, hydrogen, and oxygen, and they serve as a primary source of energy for the body. Carbohydrates can be classified into simple carbohydrates, like sugars found in fruits and candy, and complex carbohydrates, such as those found in whole grains and vegetables. When consumed, carbohydrates are broken down into glucose, which is used by the body for energy. Foods rich in carbohydrates include bread, pasta, rice, and potatoes. A balanced diet typically includes a variety of carbohydrates to support overall health and energy levels.
