Stevia is valued most for its sweet leaves and its ability to replace sugar in a diet, but stevia also contains a wealth of antioxidant compounds, such as flavonoids, triterpenes, tannins, caffeic acid, kaempferol, and quercetin, among others. The stevia plant also contains fiber, protein, iron, potassium, magnesium, sodium, vitamin A, and vitamin C.
The most important or widely praised aspect of stevia for human health concerns its ability to regulate blood sugar levels in the body. Stevia sweetens food in a similar way as sugar, but it contains stevioside, which is a non-carbohydrate glycoside compound.
Stevia is very low in calories and is anywhere from 40-300x sweeter than sugar, depending on the prevalence of certain extracts in the species variety. This means that people can eat foods like cakes, cookies, and candies made with stevia without worrying about gaining a great deal of calories from sugars, so they won’t hurt their chances of successfully losing weight.
