 • Can contribute pleasurable sweet sensations without increasing energy intake.

 • Do not increase the incidence of dental caries and may even prevent cavities.

 • Do not affect blood sugars.

 • Decrease calorie content of food.

 • Can be used in non-food items to make them taste more pleasurable.

 • Only require small amount to sweeten foods and beverages.
