Stevia
A preferred low-calorie sweetener is stevia. It is made from the leaves of the Stevia rebaudiana plant. In South America, this plant has been grown for generations for both medical and sweet purposes.
Stevia leaves contain a number of sweet compounds. Stevioside and rebaudioside A are the two primary ones. Both are hundreds of times sweeter than sugar. Stevia has a lot of sweetness but almost no calories. A few human-based research also suggest that stevia might be healthy, particularly for the following aspects of health including blood sugar and blood pressure. When used in moderation, stevia is associated with few side effects and can be a great substitute for refined sugar. But the taste of stevia is unpleasant to many people. You might need to try many brands of stevia to find one you prefer because the flavor varies by brand.
