Why carbohydrates are important
Carbohydrates are now classed in terms of their glycemic index (and glycemic load), with the dense (nutrient-rich) carbohydrates having a low glycemic index, which means they are broken down to their simplest form - glucose - over a longer period and therefore ensure that blood glucose levels are kept on a constant level.
Carbohydrates are the nutrient that provide all the cells in the body with the energy they need, through the simple sugar, glucose.
