brainConsuming a lot of aspartame may inhibit the ability of enzymes in your brain to function normally, according to a new review by scientists from the University of Pretoria and the University of Limpopo.

The review found that high doses of the sweetener may lead to neurodegeneration. It has also previously been found that aspartame consumption can cause neurological and behavioral disturbances in sensitive individuals.

Specifically, the review found a number of direct and indirect changes that occur in your brain as a result of high consumption levels of aspartame, including disturbing:
  • The metabolism of amino acids
  • Protein structure and metabolism
  • The integrity of nucleic acids
  • Neuronal function
  • Endocrine balances
Further, the breakdown of aspartame causes nerves to fire excessively, which can indirectly lead to a high rate of neuron depolarisation.

Despite these growing concerns, neither the European Food Safety Authority (EFSA) or the U.S. Food and Drug Administration (FDA) have changed their guidelines regarding the safety of the ingredient or intake advice.

What Are GMOs?

From April 19th through April 25th we launch GMO Awareness Week. We set aside an entire week dedicated to providing you with information on GMOs and labeling initiatives.

GMOs are a product of genetic engineering, meaning their genetic makeup has been altered to induce a variety of “unique” traits to crops, such as making them drought-resistant or giving them “more nutrients.” GMO proponents claim that genetic engineering is “safe and beneficial,” and that it advances the agricultural industry. They also say that GMOs help ensure the global food supply and sustainability. But is there any truth to these claims? I believe not. For years, I've stated the belief that GMOs pose one of the greatest threats to life on the planet. Genetic engineering is NOT the safe and beneficial technology that it is touted to be.

Help Support GMO Labeling

The Grocery Manufacturers Association (GMA)—Monsanto’s Evil Twin—is pulling out all the stops to keep you in the dark about what’s in your food. For nearly two decades, Monsanto and corporate agribusiness have exercised near-dictatorial control over American agriculture. For example, Monsanto has made many claims that glyphosate in Roundup is harmless to animals and humans. However, recently the World Health Organization (WHO) had their research team test glyphosate and have labeled it a probable carcinogen.

Public opinion around the biotech industry's contamination of our food supply and destruction of our environment has reached the tipping point. We're fighting back. That's why I was the first to push for GMO labeling. I donated a significant sum to the first ballot initiative in California in 2012, which inspired others to donate to the campaign as well. We technically "lost the vote, but we are winning the war, as these labeling initiatives have raised a considerable amount of public awareness.

The insanity has gone far enough, which is why I encourage you to boycott every single product owned by members of the GMA, including natural and organic brands. More than 80 percent of our support comes from individual consumers like you, who understand that real change comes from the grassroots.

Thankfully, we have organizations like the Organic Consumers Association (OCA) to fight back against these junk food manufacturers, pesticide producers, and corporate giants.

Together, Let's Help OCA Get The Funding They Deserve

Let’s Help OCA get the funding it deserves. I have found very few organizations who are as effective and efficient as OCA. It’s a public interest organization dedicated to promoting health justice and sustainability. A central focus of the OCA is building a healthy, equitable, and sustainable system of food production and consumption. That's why I'm proud to announce I will be matching donations up to $250,000 this week.

Please make a donation to help OCA fight for GMO labeling.

Dr. Mercola's Comments:

Aspartame is a poison that does not belong in your body, and this is not an exaggeration. Yet, this toxic substance is consumed by over 200 million people around the world and is found in more than 6,000 products.

Everything from soda and chewing gum to desserts, yogurt, and even some vitamins and cough drops contain it.

When you drink, say, a can of diet soda sweetened with aspartame, what are you REALLY consuming? Here’s a breakdown of aspartame’s three chemicals: the amino acids aspartic acid and phenylalanine, and methanol.

1. Aspartic acid (40 percent of aspartame)

Aspartate acts as a neurotransmitter in your brain by facilitating the transmission of information from neuron to neuron. Too much aspartate in your brain kills certain neurons by allowing the influx of too much calcium into your cells. This influx triggers excessive amounts of free radicals, which kill your cells.

The neural cell damage that can be caused by excessive aspartate is why Dr. Russell Blaylock refers to them as "excitotoxins." They "excite" or stimulate your neural cells to death.

Now, when aspartic acid is consumed, it significantly raises your blood level of aspartate, which leads to a high level of those neurotransmitters in certain areas of your brain, where they slowly begin to destroy neurons.

Your brain cells could be dying right now, but you likely would not notice the symptoms until 75 percent or more are gone. Then, chronic illnesses such as the following, which may by caused by long-term exposure to excitatory amino acid damage, may occur:
  • Multiple sclerosis, Parkinson’s disease and Alzheimer’s disease
  • Memory and hearing loss
  • Hormonal problems
  • Epilepsy
  • AIDS
  • Brain lesions
  • Neuroendocrine disorders
2. Phenylalanine (50 percent of aspartame)

Phenylalanine is an amino acid normally found in your brain, however people with the genetic disorder phenylketonuria (PKU) cannot metabolize phenylalanine. This leads to dangerously high -- and sometimes lethal -- levels of phenylalanine in your brain. It has been shown, though, that ingesting aspartame, especially along with carbohydrates, can lead to excess levels of phenylalanine in your brain even if you do not have PKU.

Even consuming aspartame one time has been found to raise your blood levels of phenylalanine. What’s the risk of this?

Excessive levels of phenylalanine in your brain can cause the levels of serotonin in your brain to decrease, leading to emotional disorders such as depression. It can also cause schizophrenia or make you more susceptible to seizures.

3. Methanol (aka wood alcohol) (10 percent of aspartame)

Methanol/wood alcohol is a deadly poison, and the absorption of methanol into your body is sped up considerably when free methanol is ingested. Well, free methanol is created from aspartame when it is heated to above 86 degrees Fahrenheit (30 Centigrade). This would occur when an aspartame-containing product is improperly stored (in the sun, for instance) or when it is heated, such as part of a "food" product like Jello.

Meanwhile, methanol breaks down into formic acid and formaldehyde -- a deadly neurotoxin -- in your body.

Even the U.S. Environmental Protection Agency (EPA) states that methanol "is considered a cumulative poison due to the low rate of excretion once it is absorbed. In the body, methanol is oxidized to formaldehyde and formic acid; both of these metabolites are toxic."

They recommend a limit of consumption of 7.8 mg/day, but a one-liter aspartame-sweetened beverage contains about 56 mg of methanol. Heavy users of aspartame-containing products consume as much as 250 mg of methanol daily -- or 32 times the EPA limit!

The symptoms of methanol poisoning are numerous and varied. They include:
  • Vision problems
  • Headaches, ear buzzing, dizziness
  • Nausea and gastrointestinal disturbances
  • Weakness, numbness and shooting pains in your extremities
  • Behavioral disturbances
  • Memory lapses
Do You STILL Believe Aspartame is Safe?

I could literally go on for days about the many problems plaguing this artificial sweetener; both the dangers it poses to your health and the blatant greed and manipulation that got it on the market.

That is why I spent years researching and writing Sweet Deception. It is the most comprehensive book on the market addressing this issue, and if you or your loved ones drink diet beverages or eat diet foods, please read it sooner rather than later.

I also highly recommend watching Sweet Misery, which is part documentary, part detective story that sheds much-needed light on the controversy surrounding aspartame.

Folks, aspartame is not your friend. It is actually responsible for 80-85 percent of the food complaints registered with the FDA!

Aside from the damage it can do to your brain, aspartame can cause cancer. One well-controlled, peer-reviewed, SEVEN-year study even found that as little as 20 mg per day can cause cancer in humans.

One 12-ounce diet soda contains about 180 mg of aspartame, so you do the math on that risk!

If you have NutraSweet or Equal packets in your home, I urge you to get rid of them. About the only good use for them I’ve heard about is using them to kill ants in your kitchen.

And if you’re consuming diet foods or drinks of any kind, toss those as well. Your health will be much better off for it.

If you find you’re still having sweet cravings or are having a hard time giving up your diet soda, Turbo Tapping is a simple tool to help you get rid of your soda addiction in a short period of time. And in the case of aspartame, getting it out of your diet can’t come fast enough.

If you have experienced a reaction to any aspartame product, report it by calling the FDA Consumer Complaint Coordinator in your area.
