As a kid I remember hearing that the artificial sweetener aspartame would neutralize your digestive enzymes, and anything else you ate that day would turn to fat. Although this makes no sense biochemically at any level, it sounded scientific enough to me and I was satisfied with it — at least enough to justify my dislike for its awful flavor. It turns out that my fat-producing claim was about the mildest of many arguments made by a growing anti-aspartame movement, and biochemically-nonsensical as it was, it was among the sanest of the arguments. Take a look at websites such as AspartameKills.com, SweetPoison.com, and Dark-Truth.org, and you'll see that a whole new breed of aspartame opponents has taken activism to a whole new level. Here are a few quotes from those web sites:

Thank you Montel Williams for having the fortitude to say: "Multiple Sclerosis is often misdiagnosed, and that it could be aspartame poisoning"

NutraSweet® killed my mother and has killed and/or wounded millions of innocent people in the US and abroad.

Aspartame converts to formaldehyde in vivo in the bodies of laboratory rats.

ARTIFICIAL SWEETENER, ASPARTAME, (EQUAL, NUTRASWEET) LINKED TO BREAST CANCER AND GULF WAR SYNDROME.

Did O J Simpson Have a Reaction to Aspartame that led to the deaths of Nicole Simpson and Ron Goldman?

THE FDA, THE INTERNATIONAL FOOD INFORMATION COUNCIL (IFIC), PUBLIC VOICE AND OTHERS ARE SCAM NON-PROFIT ORGANIZATIONS AND PAWNS OF THE NUTRA-SWEET COMPANY.

After more than twenty years of aspartame use, the number of its victims is rapidly piling up, and people are figuring out for themselves that aspartame is at the root of their health problems. Patients are teaching their doctors about this nutritional peril, and they are healing themselves with little to no support from traditional medicine.

Donald Rumsfeld disregarded safety issues and used his political muscle to get Aspartame approved.

The Nazi Scientist's Poison Projects: Poison adults with Aspartame

Because of your and/or your forbearers [sic] exposure to toxics like Aspartame, a summation of immune, mitochondrial, DNA, and MtDNA (genetic) damage has occurred in your body that has made your body unable to deal with chemical insults.

The doctor that was in charge of the lab to study Aspartame, reported that the substance was too toxic and he mysteriously dissappeared [sic] and all the paper work somehow was destroyed.

The Nazis actually won the war. They just pretended to lose so that we wouldn't notice them take over our government.

Well, that's enough for now. And if you haven't heard those, you've almost certainly received one of several hoax emails that people have been forwarding around since 1995, according to Snopes.com, giving an equally long list of untrue claims about aspartame being the cause of nearly every illness. One is even falsely attributed to Dr. Dean Edell. Suffice it to say that every possible kind of attack is made against aspartame: Pseudoscientific attacks where they throw out whole dictionaries of scientific sounding nonsense; guilt by association attacks where they mention aspartame alongside Adolf Hitler and Donald Rumsfeld; non-sequiturs like pointing out the evils of the corporate structure of pharmaceutical companies as if that is support for how and why an "aspartame detoxification" program will "heal" you of all disease; and even Bible quotations attacking aspartame. The anti-aspartame lobby appears to include everyone from alternative treatment vendors trying to sell their products, to fully delusional conspiracy theorists. Dr. Russell Blaylock, a retired surgeon turned anti-pharmaceutical author and activist, believes aspartame is part of a massive government mind-control plot:

We're developing a society because of all these different toxins known to affect brain function. We're seeing a society that not only has a lot more people of lower IQ, but a lot fewer people of higher IQ. In other words a dumbing down, a chemical dumbing down, of society. ...That leaves them dependent on government because they can't excel. ...So, you know, you can kind of piece it together as to why they are so insistent on spending so many hundreds of millions of dollars of propaganda money to dumb down society.

$2/mo $5/mo $10/mo One time

Discovered in 1965 at Searle (now Pfizer), aspartame is an artificial sweetener, aspartyl-phenylalanine-1-methyl ester. Chemistry types call it a methyl ester of the dipeptide of the amino acids aspartic acid and phenylalanine. It is 180 times as sweet as sugar, which is why it's such an effective low-calorie sweetener: It's needed in only miniscule amounts. Partly in response to all the anti-aspartame craziness out there, a group of scientists from the NutraSweet company published a 2002 review of dozens of studies and clinical trials performed worldwide in the journal Regulatory Toxicology and Pharmacology, which made the following conclusions:

Over 20 years have elapsed since aspartame was approved by regulatory agencies as a sweetener and flavor enhancer. The safety of aspartame and its metabolic constituents was established through extensive toxicology studies in laboratory animals, using much greater doses than people could possibly consume. ...Several scientific issues continued to be raised after approval, largely as a concern for theoretical toxicity from its metabolic components — the amino acids, aspartate and phenylalanine, and methanol — even though dietary exposure to these components is much greater than from aspartame. Nonetheless, additional research, including evaluations of possible associations between aspartame and headaches, seizures, behavior, cognition, and mood as well as allergic-type reactions and use by potentially sensitive subpopulations, has continued after approval. ...The safety testing of aspartame has gone well beyond that required to evaluate the safety of a food additive. When all the research on aspartame is examined as a whole, it is clear that aspartame is safe, and there are no unresolved questions regarding its safety under conditions of intended use.

And yet the claims persist unabated. Here are a few more, addressed point-by-point:

When you hear claims that are supported only by a fringe minority that's in opposition to the scientific consensus, you have good reason to be skeptical right off the bat, but it doesn't mean it's not worth looking into. Aspartame has been looked into ad nauseum even after its approval, and found safe at every try; so at some point you have to depart from rationality to continue supporting the claims made against it. Enjoy your diet Dr. Pepper, it's not going to hurt you; if it was, I'd have been dead decades ago.

I hate seeing brainless lookey see posts...But for your edification I read the abstract and concluded that Charles of LA hasnt read the paper, understood it or even ...

WHO disagrees!!!

Typical cut and paste effort Charles..

Try and top it? Only if you get lazier!

If you actually read it, you'd be embarrassed.

I suppose its common to cut and paste from ratbag sites and never read the journal. Ive seen a lot of it here in the past year..

I'll look at the paper and evaluate its data against other papers. When I get home this afternoon. (its easter, full moon, lycanthropy, yada...).

This weak internet of Pho's doesnt allow for see much in journal diagrams and Tables (Cheapo-Pho).

Its a good paper on the face of it and is worth testing against other data and data types.

I think I have seen it before.

Can you open up the response with a reply Michael?

Ethanol is the antidote to methanol poisoning. Fruits have methanol AND ethanol in about equal amounts. When aspartame breaks down in heat, there is only methanol, no ethanol.

Yeah, but that doesn't mean the amount in either type of food is even remotely toxic. And the amounts of methanol referred to are the amounts that are absorbed into your body after digestion, not in the actual food. Ethanol would neutralize methanol during *digestion*, so that effect is cancelled out - with all that into account, an apple STILL doses you with 1.5 times more methanol than a can of Diet Coke.

That also happens to illustrate that you need to consume more ethanol than you did methanol to turn on the inhibiting effect, and chemically that makes perfect sense (an excess of reactant drives the reaction).

Your body deals with background amounts of many chemicals that are toxic in large quantities and happen to show up in food or food digestion (methanol and formaldehyde in particular), and that's a fact. Deal with it and stop being paranoid over nothing.

Hard to believe that anyone is as naive as brian dunning - especially with personal case histories. I think he is a corporate shrill. I will believe the original FDA - the doctors and scientists and the case studies.

I recommend brian drinks 10 cans of diet cola per day for 1 month and puts his words to the test - then he can get back to us if he can still write.

Well, as my wife will attest, that's a pretty fair estimate of how much Diet Dr. Pepper I do drink on a daily basis, and have for many years. We all have our vices. :-)

I drink at least a liter of Coke Zero every day. I'm all fine and dandy.

As-part-a-me I have no reason to lie. I've been drinking this stuff as long as it's been out. Hasn't affected me any. I can read teleprompters better than anyone else. I can tell you that my ego devised ObamanatorCare will correct any deficiencies that Diet Pop produces. I'll bet you didn't know that not only did Al Gore invent the internet he invented Nutrasweet. Nutrasweet helps keep you focused on politics and keeps you from rambling on about nothing like what I do everyday. What I say to you all out there if you're able to follow me because of my incomplete clarity and my ability to fly on a big plane and travel the world to get exotic meals and free overnight lodging at the world's best resorts cause I'm better than all of you and you're all so ignorant about what is happening to you all because you haven't drunk enough Diet Soda to help you think like me. And you know that I'm so smart I'll be writing my next book on how I screwed you all because sure as black is in the white house I'll keep doing the things I do cause I need attention and like partying with the rich and famous and you're gonna see me starring in my own movies. I'm gonna buy B.E.T. and merge with Oprah and have a talk show all scripted and put on teleprompters to make it easy for me to look smart. Buy the time you have read this you'll have forgotten all about what was being discussed here. That's the beauty of distraction that I'm so good at! I know you'll vote for me again. I am Amuslika.
