glutamate contains manufactured free glutamic acid (glutamate), a free amino
acid that can kill brain cells, disrupt the endocrine system, and cause adverse
reactions such as migraine headache, asthma, a-fib, tachycardia, and seizures.
The first data
pertaining to toxicity of manufactured/processed free glutamate (MfG) can be
found in studies going back to the 1940s, with the first ones related to
glutamate-induced retinal degeneration dating from the 1950s. The first research
to rock the boat for Ajinomoto, Inc. (the world’s largest producer of MSG),
came from John Olney’s study “Brain lesions, obesity, and other disturbances in
mice treated with monosodium glutamate,” shown to Ajinomoto in 1968, and
published in 1969 in Science.
The 1969 report
of brain damage was followed by five
decades of research where it was demonstrated repeatedly that ingestion of
MfG will cause brain damage, endocrine disorders, and observable adverse
reactions; that free glutamate accumulated in inter-cellular spaces in the
brain will cause brain damage; and that accumulations of free glutamate are
associated with abnormalities such as addiction, stroke, epilepsy, degenerative
disorders (Alzheimer’s disease, ALS, and Parkinson’s disease, for example),
brain trauma, neuropathic pain, schizophrenia, anxiety, and depression, jointly
referred to as the “glutamate cascade.”
Data that confirm that free glutamate, monosodium glutamate, and hydrolyzed proteins cause brain damage and neuroendocrine disorders can be accessed at the Truth in Labeling website.
Discussion of flawed glutamate-industry studies can also be found at the TLC site. The story of glutamate-industry suppression of data, “The toxicity/safety of processed free glutamic acid (MSG): A study in suppression of information,” published in 1999 in Accountability in Research, can be read online by clicking here.
Since 1968, the
glutamate industry has vigorously denied monosodium glutamate toxicity. Their
use of scientists-for-hire, rigged research, infiltration of government
agencies, control of major media, and a propaganda campaign second to none, has
paid off for them as witnessed by the fact that so many are buying into the
fiction that the toxicity of monosodium glutamate, and the toxicity of its
glutamic acid are controversial.
On January 28, 2019, the SciShow on YouTube, hosted by Stefan Chin, gave us one of the finest examples of glutamate-industry propaganda seen to date, designed to convince its audience that monosodium glutamate is a harmless food additive. Chin’s recipe for deception is classic.
Ingredient 1. Talk fast. Say positive things about monosodium glutamate. Some of those good things may contradict one another, but it doesn’t matter because the audience will hear a series of confident statements and won’t have time to notice the inconsistencies.
Ingredient 2. Acknowledge that research on monosodium glutamate’s “safety” has been found questionable by some. Don’t make an issue of it, just acknowledge the criticism so no one can say that you ignored critical studies. Then simply say that science disagrees. No need to offer evidence. Just plant the seed that science says monosodium glutamate is safe.
Ingredient 3. Paint a glowing picture of monosodium glutamate. Use affirmative words and phrases in your discussion. Whether they are relevant or not makes no difference. Whether they make sense or are random phrases does not matter. Make no mention of any negatives. Your audience should have positive thoughts and take away positive images of monosodium glutamate.
Some of the phrases,
statements, and images that Chin associates with monosodium glutamate include:
“MSG is umami in its purest form”
“For love of MSG”
“The savory taste that’s taking over the culinary scene”
“A building block of protein”
“Ubiquitous in kitchens”
“Universal love for MSG”
“You’ve been team umami from the get-go”
“Love of MSG comes from biology”
mentioning the positive roles that glutamate plays when not present in amounts
needed to produce excitotoxicity, its role as an excitatory neurotransmitter is
subtlety mentioned and goosed over.
There is no mention of the fact that this excitatory neurotransmitter
kills brain cells, disrupts the endocrine system, causes adverse reactions like
migraine headache, seizures, a-fib, tachycardia, asthma and more, and is known
to play a role in neurodegenerative diseases including ALS and Alzheimer’s
disease, schizophrenia, depression, and all the other abnormalities considered
to be part of the glutamate cascade.
Ingredient 4. Once the picture has been drawn and the scene has been set, begin to twist the truth in a fashion that isn’t obvious. Chin starts by pairing the terms monosodium glutamate and umami, glutamate and umami, and glutamate and monosodium glutamate. Psychologists call this process “conditioning.” Others might call it “brain washing.”
“Umami” is a
word used for centuries by the Japanese to denote a really good taste of
something – a taste or flavor that exemplifies the flavor of a food. Umami is a descriptive term. It’s an adjective. It’s not a “thing,” it describes a
thing. Chin builds the case for using
the word “umami” as a synonym for “monosodium glutamate.” He also uses “umami”
as a synonym for “glutamate,” calling “glutamate receptors” “umami
receptors.” Throughout the balance of
his presentation, Chin uses “glutamate,” “monosodium glutamate,” and “umami”
the truth, Chin moves to misrepresentations, half-truth, and blatant lies.
Ingredient 5. Misrepresentations
To make a “misrepresentation” simply means to state as a fact something which is false or untrue. To be considered fraudulent, a misrepresentation must be false, and it must be material in the sense that it relates to a matter of some importance or significance rather than a minor or trivial detail.
Ingredient 6. Half-truths.
The legal definition of a “half-truth” is to omit or withhold a statement of fact, knowledge of which is necessary to make other statements not misleading. It would be a material omission if it relates to a matter of some importance or significance rather than a minor or trivial detail. A material omission is one of the components of fraud.
Ingredient 7. Blatant lies.
The following are examples of
misrepresentations, half-truths, and lies, taken from Chin’s “The truth about
MSG and your health” propaganda piece. These
are common to glutamate-industry propaganda.
“Glutamate is an important building block for protein. And it also helps nerve cells send signals to other cells in the body. It’s the most abundant excitatory neurotransmitter in vertebrates. Since it’s so important for our bodies…”
OMITTED: Since 1957, and particularly since 1968, there have been growing numbers of studies documenting brain damage, endocrine disorders, and adverse reactions following ingestion of MSG. The glutamate cascade has been implicated in such disease conditions as addiction, stroke, epilepsy, degenerative disorders (Alzheimer’s disease, ALS, and Parkinson’s disease), brain trauma, neuropathic pain, schizophrenia, anxiety, and depression.
“Purified MSG wasn’t a thing
until 1908” when a Japanese chemist realized that the base made from kombu
seaweed in his soup imparted a delicious flavor ….”
MISREPRESENTATION: What is “purified MSG?” The flavor enhancing component of monosodium glutamate is the L-glutamic acid that was once extracted from protein-rich foods and is now produced in large part by genetically modified bacteria which excrete glutamic acid through their cell walls. When L-glutamic acid is produced/manufactured by either method, unwanted by-products of manufacture (impurities) inevitably accompany the sought-after L-glutamic acid. Two of those impurities are D-glutamic acid and pyroglutamic acid. Other impurities depend on the source material used in producing the L-glutamic acid and the method of production. Moreover, to date, efforts to remove the impurities accompanying L-glutamic acid have been unsuccessful. Which begs the question, what exactly is “purified MSG?”
“Studies have shown that
umami functions as a flavor enhancer, creating a harmony between various
flavors ….” “A 2007 study published in
the European Journal of Neuroscience….wherein the brain activity map lit up
more from the combo of drinks….”
Studies demonstrating that monosodium glutamate and other products that contain
processed free glutamic acid cause brain lesions, endocrine disorders, and
observable adverse reactions.
“It’s an amino
acid that the human body can synthesize glutamate, but that we also get from
There is no need for humans to ingest glutamate should the body be deficient,
because glutamate can be synthesized from other amino acids.
might have been told that it’s bad for you, or causes the so called Chinese
restaurant syndrome, Science disagrees.”
Independent scientists have either read the scientific literature and concluded
that monosodium glutamate kills brain cells, is an endocrine disruptor, and
causes adverse reactions, or have no opinion on the subject. It is only those scientists who are employed
by the glutamate industry who maintain that monosodium glutamate is a harmless
“MSG stands for monosodium glutamate, the sodium salt of
FACT: Monosodium glutamate is a manufactured
ingredient/product. Glutamate is the
sodium salt of glutamic acid. Monosodium
glutamate contains glutamate, the sodium salt of glutamic acid.
“Since it’s so important for our bodies, it’s
not surprising we’ve evolved a taste for it.”
“evolved a taste for it” as in “evolution?”
FACT: Certain glutamate receptors on the tongue
have been called “umami receptors by Ajinomoto.
As marketing professionals would say, they’ve been given a name and been
“We have umami-specific receptors on or
tongues and in our stomachs”
FACT: There are glutamate receptors throughout the
human body. In 2009, Chaudhari, Pereira,
stated that “Over the past 15 years,
several receptors have been proposed to underlie umami detection
in taste buds.”
“And these drive our love for foods that contain glutamates”
FACT: This is so irrelevant it isn’t even a misrepresentation.
“And umami-rich foods have been staples in human
FACT: Glutamate-rich foods (which would necessarily
be protein-rich foods) have been staples in human diets for centuries. Umami is an adjective that means flavorful or
“It all started with a 1968 letter to the editor of the New
England Journal of Medicine.”
FACT: In 1968, the same year that Dr. Ho Man
Kwok published his letter to the editor in the New England Journal of Medicine, John Olney, M.D., determined that
monosodium glutamate administered to mice caused brain damage and endocrine
disruption. Olney reached out to Ajinomoto
U.S.A., Inc. to discuss his
findings. In response, Ajinomoto
established a nonprofit corporation, recruited scientists and others to defend
the safety of its product, and unleashed a powerful public relations
campaign. Ajinomoto’s researchers claimed to be replicating the animal work
of Olney and others who found monosodium glutamate-induced toxicity, but their
researchers did not actually replicate. Although it had been established that
brain lesions could not be identified if examination was not done within 24 hours after insult,
glutamate-industry researchers routinely examined the brains of test animals after 24 hours had elapsed. They also
used inappropriate methods and materials for
staining the material they were examining.
In the 1980s, human double-blind studies were undertaken, from
which glutamate-industry researchers would claim they found no adverse effects
from ingestion of monosodium glutamate.
For these studies, glutamate-industry researchers used of a variety of
techniques virtually guaranteeing negative results — lacing placebos with
aspartame being their fail-safe.
“The idea took hold, spurring
years of biased science based on the flawed assumption that CRS was a real
thing, and that MSG caused it.”
The idea that monosodium glutamate causes adverse reactions such a migraine
headache followed the fact that a great number of people suffered migraines and
other abnormalities after eating something containing monosodium glutamate.
“biased science,” “flawed assumption,” and “flawed assumption that CRS was a
real thing” are some of the undefined negative phrases used in
glutamate-industry propaganda to paint a negative image of those who challenge
the safety of monosodium glutamate.
“Double-blinded placebo controlled studies…have failed to
find a reproducible response to ingesting foods with MSG.”
FACT: Glutamate-industry studies have been rigged to “fail to find” responses to ingesting foods with MSG. For further details look here.
Following recitation of misrepresentations, half-truths,
and blatant lies, Chin moved to degrading those who have observed that
monosodium glutamate and other ingredients that contain excitotoxic glutamic
acid have toxic potential. The following
paragraph was taken from the video.
Emphasis has been added to point to negative references.
“While our love of MSG comes
from biology, a lot of people’s aversion to it seems to have roots in something
else entirely. Racism. It all started
with a 1968 letter to the editor of the New England Journal of Medicine…. The
idea took hold, spurring years of biased science based on
the flawed assumption that CRS was a real thing, and that MSG caused
it. Subsequent animal studies seemingly
confirmed the idea, but these often consisted of injecting super
concentrated doses of MSG directly into creature’s abdomen, which isn’t exactly
a scientific approach to determining the effects of MSG sprinkled into
saucepans. More recently research on MSG
aversion has taken into account the xenophobia and racism that fueled
it. And over the last 3 decades, a
number of double-blinded placebo-controlled studies, including studies of
subjects with reported sensitivity to MSG, have failed to find a reproducible
response to ingesting foods with MSG.”
sentence is priceless. Those
double-blind placebo-controlled studies were certainly “placebo
controlled.” The placebos used invariably
contained excitotoxic aspartame (in aspartame) or another excitotoxic amino
acid, making it inevitable that there would be as many reactions to the placebo
as there were to the monosodium glutamate test material. As early as 1978, Ajinomoto’s placebos were
being laced with aspartame.
And those “subjects with reported sensitivity to MSG”? They were college students and/or medical
school students who were paid generously to participate in the studies provided
that they said they were sensitive to MSG. No one verified that they were
actually sensitive to MSG.
Ingredient 8. Conclude with discussion of some positive thing that the glutamate industry is doing. Chin tells the audience that “Investigation into the potential health benefits of MSG is ongoing…”
The only ingredient that Chin seems to have failed to include in his recipe for deception was The Whopper — the lie that we aren’t exposed to enough MfG in processed foods to cause us any harm.
