Carbohydrates are energy! They are the sugars, starches and fibres found in fruit, grains, vegetables and milk products. They are one of three micronutrients (Carbs, Protein and fat) and are essential for proper body function. Your body uses carbohydrates to make glucose aka energy which is what allows us move, think and function. Your body can use glucose immediately or store it in your liver and muscles for when it is needed.
