Benefits Of Stevia

  • Stevia herb parts are very low in calories. Parts by parts, its dry leaves possess roughly 40 times more sweetness than sugar. This sweetness quality in stevia is due to several glycoside compounds including stevioside, steviolbioside, rebaudioside A-E, and glucoside.
  • Stevioside is a non-carbohydrate glycoside compound. Hence, it lacks the properties that sucrose and other carbohydrates possess. Stevia extracts, like rebaudioside-A, are found to be 300 times sweeter than sugar. Besides, being a near-zero calorie food ingredient, stevia extracts have several unique properties such as long shelf life, high-temperature tolerance, non-fermentative.
  • Further, the stevia plant has many sterols and antioxidant compounds like triterpenes, flavonoids, and tannins. Some of the flavonoid polyphenolic anti-oxidant phytochemicals present in stevia are kaempferol, quercetin, chlorogenic acid, caffeic acid, isoquercitrin, iso-steviol, etc. Studies found that kaempferol can reduce the risk of pancreatic cancer by 23% (American Journal of Epidemiology) [1].
  • Chlorogenic acid reduces the enzymatic conversion of glycogen to glucose in addition to decreasing absorption of glucose in the gut. Thus, it helps reduce blood sugar levels. Lab studies also confirm a reduction in blood glucose levels and an increase in the liver concentrations of glucose-6-phosphate, and of glycogen.
  • Certain glycosides in stevia extract have been found to dilate blood vessels, increase sodium excretion, and urine output. In effect, stevia, at slightly higher doses than as sweetener, can help lower blood pressure.
  • Being a non-carbohydrate sweetener, stevia would not favor the growth of Streptococcus mutans bacteria in the mouth which is attributed to be a causative agent of dental caries and tooth cavities.
