No, It’s For Real: Aspartame Causes Cancer

October 5th, 2007 | Health

cancer

There’s been a ton of debate over the years about whether or not aspartame causes cancer. Based on the evidence out there I’ve always thought it likely true. Well, the evidence continues to get more and more compelling as additional, larger studies are done.

A 2005 study was published by the peer-reviewed journal Environmental Health Perspectives (EHP). This study was significantly larger than previous ones. So what did they find?

“Our study has shown that aspartame is a multipotential carcinogenic compound whose carcinogenic effects are also evident at a daily dose of 20 milligrams per kilogram of body weight (mg/kg), notably less than the current acceptable daily intake for humans,” the authors write.

From a Medical News Today summary:

Researchers administered aspartame to Sprague-Dawley rats by adding it to a standard diet. They began studying the rats at 8 weeks of age and continued until the spontaneous death of each rat. Treatment groups received feed that contained concentrations of aspartame at dosages simulating human daily intakes of 5,000, 2,500, 500, 100, 20, and 4 mg/kg body weight. Groups consisted of 100 males and 100 females at each of the three highest dosages and 150 males and 150 females at all lower dosages and controls.

The experiment ended after the death of the last animal at 159 weeks. At spontaneous death, each animal underwent examination for microscopic changes in all organs and tissues, a process different from the aspartame studies conducted 30 years ago and one that was designed to allow aspartame to fully express any carcinogenic potential.

The treated animals showed extensive evidence of malignant cancers including lymphomas, leukemias, and tumors at multiple organ sites in both males and females. The authors speculate the increase in lymphomas and leukemias may be related to one of the metabolites in aspartame, namely methanol, which is metabolized in both rats and humans to formaldehyde. Both methanol and formaldehyde have shown links to lymphomas and leukemias in other long-term experiments by the same authors.

In other words, the argument has always been, “Well if you give someone four times their body weight in just about anything it’ll probably cause cancer.” But that’s just it: all indications point to aspartame causing cancer at or below the amounts approved for human consumption by the FDA.

Seriously. Consider not consuming this poison anymore.:

[ Update: This link points to another study that refutes the Italian study. That study was extremely large and the results are discussed on the National Cancer Institute's web page, which gives it a lot of weight in my book. But I still remain unconvinced.

The common argument of "humans are different than animals" simply doesn't hold water for me, especially when the opposing evidence did not come from actually administering the aspartame in a lab environment like the Italian study did. Anyway, I sure as hell won't be drinking the stuff, and I'll continue to recommend that my friends and family don't as well. ]

    The Ramazzini Study showed conclusively aspartame is a multipotential carcinogen. The second Ramazzini Study released in 2007 showed it only takes a small amount to cause cancer and if the baby survives from a pregnant woman using it the baby can grow up and have cancer. Aspartame is an abortifacient and teratogen.

    But this has always been known by the FDA. Their own FDA toxicologist, Dr. Adrian Gross, testified on August 1, 1985, Senate, that aspartame violated the Delaney Amendment which forbids approving anything you know will cause cancer, because it caused brain tumors and brain cancer. The Bressler Report, FDA audit on http://www.dorway.com shows how Searle, original manufacturer, tried to keep it from the FDA. FDA asked for their indictment but both US Prosecutors hired on with the defense team and the statute of limitations expired. Still the FDA revoked the petition for approval (www.mpwhi.com). See the aspartame documentary, Sweet Misery: A Poisoned World, http://www.soundandfury.tv where James Turner, Atty, explains how Don Rumsfeld got it on the market when the FDA said “NO”! But aspartame does more than cause cancer. It has an entire medical text: Aspartame Disease: An Ignored Epidemic, http://www.sunsentpress.com by H. J. Robert, M.D., over 1000 pages of the horrors caused by aspartame. Also Russell Blaylock, M.D., http://www.russellblaylockmd.com wrote Excitotoxins: The Taste That Kills, His CD, The Truth About Aspartame explains the Ramazzini Study in detail eand how industry’s rebuttal failed. The truth is out.

    Did you know you can kill yourself by drinking too much dihydrogen monoxide? A woman accidentally killed herself during a contest recently. The point of the contest? To see how much of this dangerous poison she could drink. If only the radio station that sponsored the contest knew how dangerous this stuff was before they ran this contest. Maybe that woman would still be alive today. It’s probably the FDA’s fault. Or Donald Rumsfeld’s. Or Mickey Mouse’s. I heard Kermit the Frog had a hand in it, too. We need to get those money grubbing bastards before they kill any more!!!

    POP QUIZ QUESTION #1 (from one of Dr. Martini’s old med school quizzes) —

    Here’s a list of natural compounds:

    a) tobacco b) strychnine c) hemlock d) seawater e) mouse droppings

    For five points, tell me which one(s) are safe to consume.

    Today’s Helpful Hint:

    • Wear a hat made of tin or aluminum foil. This will prevent George Bush and Dick Cheney from firing their hurricane-starting gun (which is currently orbiting the earth over New Orleans) into your brain. You wouldn’t want a hurricane in your brain, would you? Then wear a tinfoil hat. If you don’t want to make your own, you can order one at http://www.loonatic.com. Just look for ‘Dr. Gibson’s Hurricane Hat.’

    The American Cancer society, the FDA, the World Health Organization, and the Joint Expert Committee on Food Additives of the United Nations Food and Agricultural Organization.

    While I’m skeptical of the FDA sometimes, all of these organizations have said that aspartame shows no significant link towards causing cancer.

    With that said it’s like everything else. I’ve heard that baked bread, Pizza, and anything and everything causes cancer. Like many other people have said…maybe so maybe not. I wouldn’t live my life by it, but at the same time I wouldn’t go out of my way to consume as much aspartame as possible.

    Also, it can cause or mimic some diseases in people with its side effects. The important thing to remember is the “exception to the rule” rule of thumb. Just b/c someone knows someone who’s had something caused by aspartame doesn’t mean this correlates to the entire population of people who intake aspartame. There are always exceptions to the rule.

    You can check on the National Cancer Institutes website (www.cancer.gov), there is no link between cancer and sweeteners such as Aspartame and Acesulfame Potassium. Or you can call their 800 number at 1-800-4CANCER.

      Wake up and research, .Gov. You are one of the many sheep that see that is part of the Government or tied to it and believe it to be true. America is finished we have to many morons walking around, but that is what they wanted(The Elite) to begin with.

    Several people have “figured” ow many cans of soda an individual would need to drink to ingest the same amount of aspartame that was dispensed to the rats. Perhaps you need to consider the vast other thousands of products that you may also be ingesting aspartame. It is in gum, yogurt, lollipops, ice cream, toothpaste, lip balm, medications, cakes, biscuits, popsicles, mouthwash, cereal, diet foods,jams and jellies… the list goes on and on. It is estimated that there are 9000 products that contain aspartame. Soda may be the least of your worries. In regards to the links to the national institute on cancer. I urge you to not take the word of the government organizations that tell us what drugs, foods, and products are safe. Sadly, the NIC and ACI have their own profiteering agendas. I would urge you to research where their funds come from and who they really work for. It is my opinion that they dont work for the American Consumer, keeping us acurately informed in an effort to keep us healthy and out of harms way. I agree it would be wonderful to say: “the national cancer institue says it is safe, so it must be safe”. But, it just isn’t so in a world where money and greed often are elevated to a place far above truth. Question everything and take the time to do your own research in the quest for truth and knowledge. Its your health that is on the line. http://www.organicconsumers.org/Politics/cancer091505.cfm

    I came upon this posting from a link to it on facebook. That said, I am curious about something. You write, “…The common argument of “humans are different than animals” simply doesn't hold water for me…”

    I would like to ask why you say this. Having worked in the biotech industry, I can tell you that many drug candidates do well in animal trials but fail in humans. Humans are different from animals. In these studies, they speak of giving equivalent doses of aspartame to the rats. However, it is a different scale than that in humans, no matter what the concentration. Many times a reaction will work well on a small scale, but when you scale it up, it won't work. Just one of those quirks in chemistry.

    It seems everything now a days causes cancer. I guess the only true key is moderation. I mean if you smoke 2 packs of cigarettes a day for 30 years you are more likely to develope cancer than someone who just ocassionally subjects themselves to a cloud of second hand smoke. So if you drink a can of diet soda at lunch you are probally not likely to develop cancer from aspartame. On the other hand if you drink a 12 pack a day your risk will go up. Moderation is key.

    It causes cancer, and all my research points to that. Any organization that is funded by the Government will have a different story. Wake up America, your Freedoms are being taken away, and we are broke as a country and the Bankster which pull the strings of our Presidents. But as long as we have television and sports the American people will stay asleep to the very end.

    Not only does it cause cancer, it’s also neurotoxic!

    What a great substance eh?

  • Sloan

    A co-worker sent me this link a couple of months ago ( http://www.mercola.com/Downloads/bonus/aspartame/report.aspx) and at that time I thought its claims were absurd. After a good amount of research, and after reading your post and the discussion here, I think I’ll quit aspartame starting today. Thanks you everyone!
