Stevia, as the name suggests, comes from the leaves of the Stevia rebaudiana plant, a shrub native to South America.Stevia is derived from Stevia rebaudiana Bertoni, an herb native to Paraguay. Stevia leaves are about 200 to 300 times sweeter than sugar, which means you need very little to sweeten a food or drink.
Stevia is appealing to many people because it is low in calories. One packet of stevia, which is equivalent to 2 tsp. of sugar, provides 5 calories and 1 g of carbohydrates.Most plants contain sugar in their tissues, but only sugar beets and sugar cane contain enough to be efficiently extracted and turned into white crystalline table sugar. In contrast, the leaves of the stevia plant contain substances called glycosides that give it its sweet flavor. Stevia is 30 times sweeter than sugar in its whole leaf form and almost 300 times sweeter once it has been refined.
So may be you can use stevia instead of sugar in your life.
