SAFE!! Oh yes. Safe AND effective. Because I always see ZEALOUS lists of the EXTREME illnesses that are allegedly stemming from the use of aspartame I decided to keep my eye out for anyone with sense to finally say something about it or elude to any further-documented research on the artificial sweetener. And lo-and-behold, someone has. If I were in a position to do my own research in a lab I would have, believe me. Because as I've stated before all of the demonization of aspartame I've seen sounds more to me like people with illnesses looking for something to blame, and half-reading research concerning the nature of various items. Like how for a month or two a lot of people were returning their bottles of Vitamin E, because they read a sentence in an article that said Vitamin E WILL kill you, neverminding that they've already been taking it for YEARS with no viable health-concerns that can be linked to it. So here's the scoop on Aspartame: According to the August 2005 issue of Discover Magazine (mind-you, Discover makes no money from either the continued use or halted use of aspartame, thus they have no vested interest or motive to falsify information), research has confirmed that when Aspartame is digested, the methyl-ester bond does indeed break down into methanol (or wood alcohol), which then further degrades into formaldehyde. Both of these substances can be toxic in high doses. HOWEVER...if you read the WHOLE article it tells you that you'd have to drink 600...let me spell that out for you. S-I-X H-U-N-D-R-E-D cans of diet soda to get as much of either substance as is contained in a single ORANGE. That's right. Oranges will kill you faster than aspartame will. DAMN! Never trust citrus I tell you. Bottom-line is Aspartame is the single-most studied and clinically tested sweetener available. And not one study has linked it to any harmful effects. Sugar, now that's another story. DIET SODA FOR ALL!!
