@Wak Well I would be very careful where I got my information from. Mercola, along with Rense, Prison Planet and Natural News all see conspiracy and will often reject consensus thinking on medical treatments and procedures in favour of their own conspiracies.
Aspartame is a case in point. There were indeed some potentially shady goings on when the product was first introduced, back in the 1970s - and the subsequent objections and those allegations tainted the history.
However, since then there have been many reviews and studies on the safety of aspartame, and the safety of the product has been conclusively proven.
One of the major claims in your reference, for instance, suggests that industry trials were uniformly positive, independent trials were universally negative - but closer examination of the references shows that Dr. Olsen left out 50 peer reviewed studies, all of which demonstrated aspartames safety. Closer analysis of the citations alleging that aspartame were unsafe were often found to be unpublished letters, small studies that were not peer reviewed, even just chapters from books.
In short, the evidence offered was extremely poor and he had cherry picked his references in an effort to bias the findings. Shoddy science at best, deliberate misdirection at worst.
This false controversy has resonated through the decades, affecting other countries who have been affected by the controversy.
The European Food Safety Authority recently conducted the most comprehensive review yet, using 600 data sets, including the first 100 or so original studies submitted when application was originally made for aspartames introduction into Europe.
This is their conclusion.
"On January 8, 2013, the EFSA released its draft report, which found that aspartame and its metabolites "pose no toxicity concern for consumers at current levels of exposure. The current Acceptable Daily Intake (ADI) is considered to be safe for the general population and consumer exposure to aspartame is below this ADI"
Wiki have a good page on the whole aspartame conspiracy theories and the testing to show its safe, for those willing to take the trouble to look.

Another good, objective site which examines the whole sorry saga of the hysterical claims about the dangers of aspartame can be found here

You should also make yourself familiar with the breakdown products of aspartame, the metabolites - all of which naturally occur in the body.
In fact, the only people who have to worry about aspartame are those who have a rare autosomal recessive ,metabolic genetic disorder called PhenylKetonUria or PKU, who are unable to metabolise phenylalanine, which is found in aspartame. This genetic disorder is thought to affect 1 in 10,000 individuals.

Its a free country, and of course you are at liberty to avoid it if you want - but do not let yourself be misled by sites like Mercola....
