Sorry but the whole "made from sugar" thing is total propaganda on the part of Splenda's marketing department. It actually is a chlorinated carbon that literally does not exist in nature. (I'd point out that pesticides fall under the same catagory of chlorinated carbon compound.) Your body doesn't know what to do with it and thus you have almost no net calories from it as your body rejects it as a foreign object. However, there is no formal testing to determine how much of the chlorine is actual absorbed and even the Splenda manufacturer says a "small percent" (between 11-27% estimate) is absorbed into the body. Additionally, no long term studies have been done on the product, nor any independant studies. (Only those funded by the makers of the product.)
Just a reminder that marketing is meant to sell a product. Not give the truth.
