Stevioside is a non-carbohydrate glycoside compound. Hence, it lacks the properties that sucrose and other carbohydrates hold. Stevia extracts, like rebaudioside-A, are found to be 300 times sweeter than sugar. In contrast to sugar, however, stevia extracts have several unique properties such as long shelf life, high temperature tolerance, non-fermentative and at the same time, being near-zero calorie item.
No Glycemic response
The relative ability of a carbohydrate food to increase the level of glucose in the blood is called glycemic response. Stevia contains no carbohydrates and no calories and accordingly has a glycemic index of zero. A zero glycemic index score means that eating stevia will not raise your blood sugar.
No Bitterness or aftertaste (Sachet and Liquid form)
The stevia leaf when consumed directly has slight bitterness or a metallic aftertaste. The sachet and liquid stevia product contains some Organic taste modifiers, which fill up the hollowness of the stevia sweetness, Filler component which imperts mellower sweet mouthfeel and absorbs bitterness.
No Artificial Ingredients
The filler components used are natural and organic.
Helps in weight Lose
The replacement for sugar with stevia products may also reduce the number of calories that a person consumes, which is likely to aid in weight loss.
Balances Blood sugar
Chlorgenic acid reduces 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.
Control Blood Pressure
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.
Unlike Sugar Prevents Tooth Cavities
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. On the other hand, certain compounds in stevia rather found to inhibit caries causing bacteria in the mouth.
In addition, stevia plant has many sterols and antioxidant compounds like triterpenes, flavonoids, and tannins. Some of flavonoid polyphenolic anti-oxidant phyto-chemicals present in stevia are kaempferol, quercetin, chlorogenic acid, caffeic acid, isoquercitrin, isosteviol…etc. Studies found that kaempferol can reduce risk of pancreatic cancer by 23% (American journal of epidemiology)
The tannins in green leaves has the ability to prevent the body cells from ageing. These help in keeping the body cells more agile and active.
In addition, being a herb, stevia contain many vitals minerals, vitamins that are selectively absent in the artificial sweeteners.
Stevia plant uses in traditional medicine
Stevia extract has been in use by native South Americans (where it is known as caa-he-éé or kaa jheéé) to reduce weight; to treat wound infections, inflammatory conditions, swelling in the legs and as a tonic to treat depression.
