How do Carbohydrates help your body function properly?

Answer 1

Complex carbohydrates are best: Carbohydrates are an important part of a healthy diet and provide the body with the fuel it needs for physical activity and for proper organ function. Also... Some of these fuels are stored in your body so that muscles and organs can use them as an immediate source of energy.
