Why the Sweetener Called "Aspartame" Is a Deadly Toxin?
Aspartame, an artificial sweetener found in diet sodas and other sugar-free foods, is one of the most toxic substances that is added to food. This sweetener, commonly marketed under brand names like NutraSweet or Equal, generally appears to cause slow, silent damage to health that accumulates over the years, through long-term use. aspartame, like the flavor enhancer monosodium glutamate is a neurotoxin and has been linked to causing over 90 different side effects ranging from headaches, seizures, memory loss, joint pain, brain tumors, and even death. It has been linked to physical, visual and mental problems, and mimics the symptoms or worsens the condition of various diseases.
Aspartame and brain Tumors
In a two-year study conducted by the manufacturer of aspartame, twelve of the 320 rats tested fed a normal diet and aspartame, developed brain tumors while none of the control rats had tumors. Five of the twelve tumors were in rats given a low dose of aspartame.
A closer look at aspartame's ingredients and its adverse reactions reveal the dangers of this artificial sweetener.
Eliminate Aspartame from your Diet and the Diet of your Children
Despite all of these harmful effects, aspartame is an "approved sweetener" and is found in many common foods and drinks. To protect yourself from the damaging effects of this toxin, eliminate it from your diet. Aspartame is sometimes labeled as phenylalanine in foods. As you can see below aspartame is used in many products that children regularly consume.
It can be found in:
* soft drinks, usually diet soft drinks
* sugar-free chewing gum and breath mints
* instant breakfasts
* juice beverages
* milk drinks
* tabletop sweeteners
and many other foods.
How aspartame Causes Damage
Aspartame is made up of three chemicals: Aspartic acid (40%), phenylalanine (50%), and methanol (10%).
Aspartic acid (40% of Aspartame)
Both aspartate (aspartic acid) and glutamate (found in the flavor enhancer monosodium glutamate - MSG!) are amino acids and work in the same way in the body. They act as neurotransmitters in the brain by aiding the transmission of information from neuron to neuron. Too much aspartate or glutamate in the brain kills certain neurons by allowing an influx of calcium into the cells. This influx triggers excessive amounts of free radicals, which kill the cells. This neural cell damage that can be caused by excessive aspartate and glutamate is why they are referred to as excitotoxins. They "excite" or stimulate the neural cells to death.
Because aspartate and glutamate are amino acids, when they are ingested in their free form (unbound to proteins), they significantly raise blood plasma levels of these chemicals. This excess leads to a high level of those neurotransmitters in certain areas of the brain.
Usually the blood brain barrier protects the brain from excess glutamate and aspartate as well as from other toxins. However in children it is not fully developed, or it can become damaged by numerous chronic and acute conditions, which can allow leakage of excess glutamate and aspartate into the brain. This excess glutamate and aspartate slowly begins to destroy neurons. The large majority (75% or more) of neural cells in a particular area of the brain are killed before any symptoms of a chronic illness are even noticed. Some of the many chronic illnesses that have been shown to be contributed to by long-term exposure to excitotoxin damage include:
Multiple sclerosis (MS), motor neuron disease, hearing loss, epilepsy, Alzheimer's disease, Parkinson's disease, hypoglycemia, dementia, brain lesions, and neuroendocrine disorders.
Phenylalanine (50% Of Aspartame)
Phenylalanine is an amino acid normally found in the brain. People with the genetic disorder, phenylketonuria (PKU) cannot metabolize phenylalanine, leading to dangerously high levels of phenylalanine in the brain. But even in people who do not have this disorder, it has been shown that ingesting aspartame can lead to an overload of phenylalanine in the brain.
Excessive levels of phenylalanine in the brain are associated with causing levels of seratonin in the brain to decrease, leading to emotional disorders such as depression, schizophrenia and brain damage. It was shown in human testing that phenylalanine levels of the blood were increased significantly in human subjects who chronically used aspartame. But even a single use of aspartame raised the blood phenylalanine levels, which is especially dangerous for infants and fetuses. Another study showed that phenylalanine is metabolized much more efficiently by rodents than by humans.
Methanol (10% of Aspartame)
Methanol, also known as methyl alcohol or wood alcohol, forms 10% of aspartame, and is a deadly poison. Free methanol, such as that formed from aspartame when it is heated or stored for a long time, breaks down into formic acid and formaldehyde in the body. Formaldehyde is a known deadly neurotoxin. The recommended Environmental Protection Agency limit of consumption is 7.8 mg/day. A one-liter aspartame-sweetened beverage contains about 56 mg of methanol.
Formaldehyde is also a known carcinogen, is also linked to causing blindness, retinal damage, interfering with DNA, and causing birth defects. Due to the lack of a few key enzymes, humans are many times more sensitive to the toxic effects of methanol than animals. Therefore, tests of aspartame or methanol on animals do not accurately reflect the danger for humans.
