Does Stevia contain calories?
Even though glycosides are so-called carbon compounds in which sugar molecules are linked to alcohol, 100mg of steviol glycosides contain only about 0.5 calories. To achieve a comparable sweetness, you would need about 30g of sugar (125 kcal). The reason for this small amount of calories is that the sugar contained in the steviol glycosides is not broken down by the digestive tract, but is removed directly.
Although carbohydrates are also absorbed when consuming Stevia, the energy balance remains unaffected. This is due to the indigestible molecular structure of the carbohydrates.
Industrially manufactured Stevia products may contain energy carriers or fillers. In most cases, however, the amounts are very small so that even diabetics can neglect them in terms of calories.
