poisonbottle 255x159 Aspartame Cancer Link Exposed: Increasing Your Cancer RiskThere have been several studies over the years that established a link between aspartame consumption and cancer risk. But, these studies were frequently criticized as being too small, only capturing a short period of time, and otherwise not living up to strict scientific standards. A new study, however, addresses these concerns and substantiates what the previous ones already said: that aspartame in diet soda can increase your risk of certain types of cancer, exponentially. It seems the aspartame-cancer link has been exposed…again.

The Aspartame-Cancer Link

Scientists looked at data from the Nurses’ Health Study and the Health Professionals Follow-Up Study for a period of 22 years, including over 77,000 female study subjects and nearly 48,000 males. In all, the giant study looked at “2,278,396 person-years of data”, the most of all previous aspartame studies.

Study participants were asked about their diets every two years. In prior studies, questions about aspartame were only asked once, opening them up to error and criticism. What this study found, however, is frightening.

One can of diet soda each day can increase leukemia risk in men and women by 42 percent, increase multiple myeloma risk in men by 102 percent, and increase the risk of non-Hodgkin lymphoma by 31 percent in men.

The results are frightening, but not surprising. Though previous research was criticized for not being scientifically sound—the findings were similar. Another study focusing on the aspartame-cancer link found that of 48 rats experimented on, up to 67% of all female rats developed tumors roughly the size of golf balls or larger. The male population also suffered, with 21% of the males developing similar cancerous growths.

What’s possibly even more concerning is that aspartame is created using genetically modified bacteria. Revealing how aspartame is made, an article from The Independent reports that both a Monsanto source and a Monsanto spokesperson admits that aspartame creation process did in fact involve genetically modified bacteria.

“We have two strains of bacteria – one is traditionally modified and one is genetically modified,” said the source. “It’s got a modified enzyme. It has one amino acid different.”

Stay Away

Although there are other sources of aspartame, diet soda remains the most popular. If you were ever wondering, ‘is diet soda bad for you‘, the answer is a sound ‘yes’. In the United States, we consume an estimated 5,250 tons of aspartame each year, of which 86% is in the form of diet sodas.

Recognizing the dangers of diet soda, many people limit themselves to just one can each day. But this latest research shows that one can is enough to do significant damage. And, switching back to a sugared soda isn’t any better—researchers found men drinking one or more regular sodas saw a 66% increase in non-Hodgkin lymphoma.

What’s the solution? Quit drinking soda. If you’re in it for the caffeine, try green tea and it’s many benefits or even coffee. If you prefer cold and refreshing, have iced tea.

Changing your habits takes motivation and dedication (follow-thru). This research showing the aspartame-cancer link yet again should provide the motivation, but it’s up to you to take steps towards reclaiming your health.

    Well, it’s been over a year since you posted this but I still had to comment. The abstracts provided in the article concluded that there was no correlation between diet soda and hematopoietic cancers. Googling it leads to the same conclusion if you look for scientific data. You can find sites that support the claim that aspartame causes cancer but no studies to back up the claim. I think Pilgrim is correct based on science, At
    least at this point.

    My study Is conclusive! Aspertame is Poison and Will KILL YOU… Slowly. I just met a woman who is poisoned with aspertame. She has suffered for years with no answer from the dr.. Same old story. I went through the same things she is experiencing. I noticed it right away and shared my info with her. I haven't ever studied to be a Dr but I diagnosed her after knowing her for a few days. She is now off the aspertame for 3 days and is already strating to feel better. Our Goverment is making millions of people ill and nobody wants to accept this. Something is WRONG and we need to do something about this! This is a MASS Murder and we are blind to it… Open your eyes.. Monsanto is a Murderer . Pump him full of his aspertame and see how he feels.

  • Tammy

    I can’t stand to see people say that aspertame poisoning isn’t a fact. I can tell you first hand it is. I suffered for years with no answers. NEVER one answer! They tried diagnosing me with multipule disorders. Nothing ever felt right.. How can I have so many disorders. The answer was Aspertame poisoning. I suffered for 12 YEARS. Once I realized this might be the problem I quite using splenda and anything diet. I can tell you I am no longer suffering like I was. I feel like a normal person again. I was robbed of so many memmories because I was to sick to experience them. I’m still healing, I have been aspertame free for about 6 months now. This is the only thing I eliminated from my diet that made me well again. Aspertame should be illegal and shouldn’t be sold on any shelf in the world. Shame on you Monsanto!

    The first two additional sources are quite old and the third states that their study wasn't conclusive.

    Sugar is addicting so beverage industries use sweeteners to enhance the taste. That said, I maybe this is a wake up call for society.

  • Kat

    It's not necessary to put it in sodas, but they do it to make money and keep customers….

  • sheridan

    Here's a factsheet on the links between cancer and artificial sweetners:

  • sheridan

    I did do some research previously and found there to be little evidence of detrimental effects of Aspartame, but I checked out the article anyway and it pointed to some interesting things.

    There is a link between cancer and Aspartame in rats, but at consumption levels of 20mg/kg body weight. This works out at around two thirds a jar of my artificial sweetner, which takes me usually two to three weeks to get through.

    I found however that the article is not very well referenced, and makes unfounded claims about a study that links aspartame to cancer. Although it does not reference the study, I managed to find it anyway, and the study is not actually about Aspartame, but is about "Consumption of artificial sweetener- and sugar-containing soda", so it's about soda in general, not aspartame specifically.

    Sugar in itself is really bad for you in many ways, this has been scientifically proven. Also anything can be bad for you in large enough quantities – the lethal dose of water is 80 glasses in one hour. But as for Aspartame, it is still the most highly tested food additive on the market, and it's still out there on the shelves. I have to have a little faith in our government that they are not trying to poison us all!

    There's a hell of a lot of misinformation about artificial sweetners, and I really don't know why, (maybe stuff put out by the sugar industries?) but I'll continue to be cautious about what I eat and maybe I will try to cut down a little, just to be on the safe side.

    Gave up diet coke , Or any soda , only drink mint tea ,soya milk, water, lost nine ten stone in 15 months, feel brilliant. . Never touch anything with aspartame in it again , stop all this disbelieving. Just give it up. It's crap

    • BritishNinja

      Good on ye, mate!

  • QuentonQuale

    Aspertame is 11% methanol by weight. Go to to read about the dangers and side effects of this toxic substance. I wouldn't be proud of the fact that you consume so much of that garbage. You probably never connect your health problems to your food and drink intake.

    Most websites with "natural" in the url have an agenda. Why are the "facts" in this article not found elsewhere? I love diet soda; I drink lots of it! In the last 25 years I've probably drunk more than enough to cover 1 can/day for the rest of my life, and I'm < 40. *gets up and goes to the refrigerator for another one*

  • theotherdy

    The final line of the paper you're reporting (the last of the three pubmed links) says:

    'the inconsistent sex effects and occurrence of an apparent cancer risk in individuals who consume regular soda do not permit the ruling out of chance as an explanation.'

    Given all the other evidence of no ill effects: e.g.… and… this blog seems to be overstating the dangers somewhat…

    Aspartame has given me a headache every single time without fail. There's also numerous documentaries about how it crippled lives.

    Thanks Donald Rumsfeld for making it available to kill us once again!

  • Pilgrim

    Sounds like alarmism to me. Why didn't the author of this article link or provide a title to said "new study"? Why doesn't the American Cancer society know about this "new study"? The first two additional sources are quite old and the third states that their study wasn't conclusive.

    • Jacob

      You're funny, like the American Cancer Society is actually attempting to get to the root of the disease.

      • Pilgrim

        Funny? What's funny is when someone yells the sky is falling, but doesn't tell you where they get their "facts". I personally avoid artificial sweeteners – Why take an unknown risk? Yet this article claims the risk isn't unknown, but it fails to provide verifiable evidence. Every reputable study I've read has had confounded results. I'd like to read the study this article references, but I'm left to wonder if it even exists.

        • KarateGirl

          Did you bother to follow the links at the bottom of the article before poo-pooing all over it? Or the gods forbid you Google it yourself – it's all right there, Doubting Thomas.

    • Sandra

      The cancer society is in the business of making money if you research them you will find the bulk of the money that isn't spent on ludicrous salaries goes to advertising for there next fundraiser. Not one of these organizations are in it for finding a cure. It's one of the largest scams of all time. Whether its cancer, ms, lung or whatever.

    I hate diet sodas containing aspartame. Don't you?

    Nothing is as dangerous as aspartame. I have studied it carefully since it came on the market. My first cup of it gave me a horrible optic migraine.

    it caused a drastic personality change and intellectual deterioration in my daughter. She also developed epileptic-type seizures and began to lose the vision in both eyes!!!

    She also began having severe headaches and more.

    She consulted a neurologist, and he told her that she had temporal lobe epilepsy.

    He began treating her with medication, but the medication didn’t work,

    because the doctor was wrong in his diagnosis and he was treating her for a
condition she didn’t have! What she really had was a reaction to ASPARTAME
I heard about Dr. H. J. Roberts in Florida, so I contacted him and he
confirmed what I suspected – that she was suffering from a reaction to the
artificial sweetener in diet soda. He has written many medical texts about aspartame.

To follow up, we took our daughter to Boston for special studies on her brain, and
the doctors confirmed that it was the NutraSweet that had made her so sick.
They said that she had been totally misdiagnosed by the neurologist and that
she did not have temporal lobe epilepsy at all. (These men were in the
Clinical Research Center at the Massachusetts Institute of
Technology.). We also took her to a highly-respected ophthalmologist who
explained why her vision loss was due to aspartame.

    She finally stopped drinking sodas containing aspartame, and she had a complete recovery and has had a fine job since then as a computer programmer and financial analyst and Actuarial Systems Sr Specialist.

    One note on this: regular sugared soda usually has high fructose corn syrup which is also GMO. So, it makes sense that regular sugared soda is just as dangerous as diet soda with aspartame.

    • Jason

      Actually, that's not true. While I don't advocate GMO consumption, stating that all GM foods have the same effect is like saying all chemical-containing substances have the same effect when ingested. I'll gladly take soap over draino.
