The role of carbohydrates in the daily diet is to provide the body's chief source of energy.Carbohydrates are divided into three groups according to the complexity of their molecules: simple sugars,complex carbohydrates,and dietary fiber.Simple sugars are formed in the mouth from refined carbohydrates,and most refined carbohydrates supply only "empty" calories.Complex carbohydrates,which are found in grains,vegetables,and fruits,are important because they provide energy.Fiber's primary function is to provide bulk for normal gastrointestinal functioning.
Proteins are the nutrients that build and repair tissue.
In contrast to complex carbohydrates,most refined carbohydrates supply only "empty" calories and many are high in fat.
Fats can also provide energy,but they are not the body's chief source.
