Stevia is a plant-based sugar substitute that has no calories. The term “stevia” refers to Stevia rebaudiana, which is a South American plant. Only certain parts of the plant are sweet. Highly purified extracts from the leaves of the plant are called “steviol glycosides.” They are 200 to 400 times sweeter than sugar.Stevia is used as a substitute for sugar.
Recent research has shown that stevia acts on pancreatic tissue to elevate the insulin level and exerts beneficial anti-hyperglycemic effects through the PPARγ-dependent mechanism and stevia’s antioxidant properties. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4842244/).
