The OH soo Sweet Stevia

If one were to look up Stevia on the internet, you may find it was discovered by Paraguay. However, it is known that the Guarani Indians of South America assumed that the leaves of the plant had a significant value. If you chew the leaves they have a very unique and refreshing taste. It was not long after the discovery in the 1800’s that Paraguay took the shine for Stevia. It was used in teas, foods an a number of other mixtures. Once Fracne got a hold of this sweet plant, two chemist were successful in extracting crystalline compounds, known as steviosides Now in the Japan in the 60’s Steviosides were very useful, as Japan had outlawed chemical products in food. By 1990, Japan had accounted for over 40% of the word’s use of Stevia. The US banned the use of Stevia in 1991 for its questionable safety, to be later contradicted.
Stevia is nothing but a natural sweetener, which contains 100 phytonutrients. It does not have any calories and does not promote tooth decay.
Okay so theres all this good information on stevia from one article I read. Then when I looked it up online I saw all the studies one it, I guess from 1991, which said it was once handled as if were an illegal drug. Websites also stated it could not even be considered a sweetener? Now who do you listen to? I guess this is kind of like the whole debate between splenda being a carcinogen or consuming raw sugar.
