Stevia is a natural sweetener. The nature offers salvation in diabetics and in those who take care of their nutrition. Stevia is a tiny shrub. It Comes from Latin America and is cultivated in many regions of the world, mainly in China. Experimental cultures of stevia exist in Greece, in farms of Thessaly and Macedonia. The leaves of stevia contain various natural sweeteners, such as stevioside and rebaudioside, which make stevia 60-80 times sweeter than the common sugar. Stevia is the only natural sweetener with zero calories, zero carbs, zero glycemic index (G.I.) and zero glycemic load (G.L). Therefore, when it used in place of common sugar or other caloric sweeteners (fructose, honey, agave syrup), helps in weight loss for all those who want sweet, but also those who for health reasons can not taste sweets.
