Mainlining delivers toxins better

The Glutes make a big deal out of the fact that some of the studies of MSG-toxicity were done with MSG administered by injection to newborns animals  (conveniently forgetting the fact that other results of MSG-induced toxicity were based on feeding studies).

They suggested that injection of MSG is more lethal than ingestion of MSG, and in humans, they said, MSG isn’t injected.  But that’s not entirely true.  The MSG used in vaccines is injected. Drawing on drug-culture vernacular, one could say that the MSG in vaccines is mainlined.

The CDC list of vaccines and their excipients/additives follows.  Highlighted are ingredients that contain the excitotoxic free glutamate found in MSG.

Bless you Dr. Tetyana Obukhanych for speaking out

Animal studies tell us that the glutamic acid in MSG, autolyzed yeast, maltodextrin, glutamic acid and the 40+ other ingredients that contain manufactured free glutamic acid causes brain damage – kills brain cells. Those who manufacture and sell the products that contain excitotoxic glutamic acid tell us that those were just animal studies and they don’t matter.

Ajinomoto, world’s largest producer of MSG tells physicians, the FDA, the World Health Organization, the media and everyone else that there are hundreds of studies showing that MSG is harmless. I’ve read all of them and can tell you that their animal studies were rigged to look for the wrong thing in the wrong place, at the wrong time, making their report of “no brain damage” meaningless.

The ways in which human studies were rigged are too numerous to discuss here, but basic to most has been use of excitotoxic aspartic acid as a placebo in double-blind studies of excitotoxic glutamic acid. In those studies, both the excitotoxic monosodium glutamate test material and the placebo which contained excitotoxic aspartic acid, triggered the same reactions (as they always do). In other words, not only did subjects react to MSG, they reacted to a “placebo” that contained an excitotoxin known to cause the same reactions as those caused by MSG. It is on these studies (which actually describe reactions caused by MSG), that the Glutes base much of their claim that MSG does not trigger reactions.

Read what immunologist Dr. Tetyana Obukhanych tells us about vaccines. It appears those who profit from the sales of vaccines have the same teachers and/or use the same PR firms as those in the glutamate industry, Big Tobacco, the purveyors of toxic pesticides and fertilizers and the corporations that spew cancer-causing pollutants into the air. Individual welfare can’t hold a candle to the economic welfare of the rich and powerful.

Dietary guidelines for Americans. An ongoing food industry joke.

It was thirty years ago, but it seems like just yesterday. Despite an allergy to petrochemicals that was so bad I couldn’t tolerate reading a newspaper, on that particular Thursday I picked up Jack’s Chicago Tribune, turned to an inside section and read the announcement that the FDA was holding hearings and asking for input on nutritional labeling that would soon be appearing on food labels.

Over the weekend I worked nonstop to convince Jack he had no choice but to attend. This was a once-in-a-lifetime chance. He had to give testimony to the fact that monosodium glutamate used in food causes adverse reactions. And on Monday he called the FDA Chicago office requesting permission to testify.

Dr. George Schwartz flew in from Santa Fe to take part in the hearings. We had read his book, In Bad Taste: the MSG Syndrome, but had not yet met him. We also met Barbara Mullarkey, who introduced us to the horrors of vaccines as well as various toxic foods. But it was Big Food that stole the show. They were there, all of them, representatives of major food companies each pretending to suggest labeling that would benefit consumers, while actually pushing ways to hide the salt, sugar, trans fats and any of the other undesirables that permeated their products.

I hadn’t thought about those days for years. Then a press release issued by the Nutrition Coalition titled “Member(s) of USDA committee blow whistle on serious flaws in dietary guidelines process,” arrived in my inbox. The first sentence summed it up, saying: “One or more Members of the Dietary Guidelines Advisory Committee Suggest Process Lacks Scientific Integrity and Rigor.” (The Dietary Guidelines are promoted by the Secretaries of Agriculture and Health and Human Services as “information that helps Americans make healthy choices for themselves and their families.”)

Could it be? Isn’t Big Food still in charge of safeguarding the many secrets of those harmful ingredients used in food, typically well hidden from consumers? Did someone object to the fact that while the Dietary Guidelines spoke of nutritional value and healthy eating patterns, they didn’t mention avoidance of toxic food additives?

The whistle-blowing letter was dated June 2, 2020, addressed to Department of Agriculture Secretary Sonny Perdue and Alex Azar, Secretary of the U.S. Department of Health and Human Services. The critic(s) provided details of reviews that were unreliable and scientific evidence that was excluded. “Ensuring that all the best and most current science is properly reviewed for the purposes of establishing the 2020 DGA (Dietary Guidelines for Americans) is fundamental, and any action to rely upon unreliable reviews or exclude scientific evidence must be considered flawed. The thought that many dozens, if not hundreds of scientific studies are being excluded by the DGAC (Dietary Guidelines Advisory Committee) is unconscionable.”

Who are these people, the 20 nationally recognized experts chosen to serve on the independent 2020 DGAC? Their charge is to review scientific evidence on topics and questions identified by the Departments of Agriculture and Health and Human Services and provide a report on their findings to the Secretaries.

The DGAC chairperson and one other are at the University of California, Davis, home of one of our finest programs for food technology, serving the interests of Big Food. One is at the Baylor College of Medicine, Baylor being on record as hosting research initiated by glutamate-industry interests. One is at the University of Iowa, seat of the original industry-sponsored deceptive and misleading studies of the safety of MSG and aspartame. Possibly all belong to the Institute for Food Technologists, professional designers of chemical-laced foods.

Why would some of these people provide reviews that are unreliable and/or omit relevant studies from consideration? Do some or all of these people serve the interests of Big Food just as Andrew G. Ebert, Ph.D., toxicologist, respected member of the Institute for Food Technologists, and unacknowledged chairman of Ajinomoto’s International Glutamate Technical Committee served the glutamate industry until he was exposed for supplying placebo material containing excitotoxic aspartic acid to researchers doing industry’s double-blind studies of the safety of MSG?

The question remains unanswered. Did someone object to the fact that while the Dietary Guidelines spoke of nutritional value and healthy eating patterns, they didn’t mention avoidance of toxic food additives?

Some basic truths about MSG toxicity that the people at don’t seem to want you to know

A friend for whom I have the greatest respect is a big fan of Michael Greger M.D. FACLM. To hear her talk, you’d think he walked on water. Personally, I didn’t much care for his style of presentation, and he seemed somewhat shallow on matters I know a bit about. But with several best-selling books and posts with catchy headlines such as “Does Cholesterol Size Matter?” and “Eat More Calories in the Morning than the Evening,” he has a legion of followers.

The announcement that Dr. Greger was going to do a series of video posts on obesity, really caught my attention. I’ve been interested in obesity for over 50 years. That’s how long I’ve known that MSG causes obesity. And I was excited that Dr. Greger might be going to share facts about the toxic effects of MSG. How MSG causes a-fib, migraine headache, fibromyalgia, skin rash, seizures, infertility, brain damage and more, not just that it causes obesity.

My excitement, however, was short-lived. Seems that even suggesting that MSG might cause obesity isn’t on Dr. Greger’s agenda. How do I know? Because I went to great lengths to contact him and suggest that MSG-related obesity was something he should look into. And on May 5, 2020 Christine Kestner, MS, CNS, LDN (Health Support Volunteer) responded:

“Hi, Adrienne Samuels! You can find everything on this site related to MSG here: While it is true that this topic has not been updated in a while, a quick look at the lates research indicates that nothing has really changed in the last decade or so. We base our videos on the research, and not on industry influence. If you are aware of quality, peer-reviewed research that contradicts our positions, please share it with us.”

So, I did. I sent her pages of fully-referenced information. And then I waited. And waited. And then I sent a “You did get my letter, didn’t you?” note. And I’m still waiting.

Below is a copy of the material on MSG toxicity that Dr. Gregor ignored – or maybe Christine Kestner never showed it to him. Could be. Such is the power of the glutamate industry.

You’ll find the references for all this material at the end of the letter.

May 6, 2020

Thank you Christine,

The opportunity to provide accurate information about the toxicity of manufactured/processed free glutamate acid is much appreciated.

But first, two clarifications are in order. We generally speak of “MSG reactions,” but those reactions are actually caused by the Manufactured/processed free Glutamate (MfG) component of MSG. MfG is found in more than 40 food ingredients in addition to MSG. The animal studies listed below were done using MSG to inflict brain damage.

Second, glutamic acid will either be bound with other amino acids in protein or free. Bound glutamate does not cause brain damage or adverse reactions. Only glutamate in its free form causes brain damage and adverse reactions. This distinction is an important one, because failing to make it enables the fabrication of disinformation.

You said that a quick look at the latest research indicates that nothing has really changed in the last decade or so, but that is not entirely true.

I. MSG-induced brain damage. The seminal and definitive studies of MSG-inflicted brain damage were done in 1969 and the 1970s, and there is no need to replicate them.

In the late 60s, Olney became suspicious that obesity in mice, which was observed after neonatal mice were treated with L-glutamate for purposes of inducing and studying retinal pathology might be associated with hypothalamic lesions caused by L-glutamate treatment; and in 1969 he reported that L-glutamate treatment caused brain lesions, particularly acute neuronal necrosis in several regions of the developing brain of neonatal mice, and acute lesions in the brains of adult mice given 5 to 7 mg/g of glutamate subcutaneously (12). Research that followed confirmed that L-glutamate induces hypothalamic damage when given to immature animals after either subcutaneous (13-31) or oral (19,25-26,28,32-36) doses.

This work demonstrated that when there is a vulnerable target (a brain or portion of the brain that is unprotected or vulnerable to attack from toxins), and there is glutamic acid (glutamate) in quantity sufficient to cause it to become excitotoxic, glutamate fed in quantity to immature animals causes acute neuronal necrosis in several regions of the developing brain including the arcuate nucleus of the hypothalamus, followed by behavior disturbances and endocrine disruption which includes obesity and infertility.

A recent review suggests that glutamate/MSG passed to fetuses and neonates by pregnant and/or lactating women causes brain damage, disrupting the endocrine system (99).

It will be argued by agents of the glutamate industry that these studies of brain damage were animal studies not human studies, and that is true. But studies wherein possible toxins are fed to pregnant women and brains of their offspring are examined would certainly be questionable at best on ethical and moral grounds. Researchers rely heavily on animal studies to suggest solutions to problems of human dysfunction.

II. Industry’s unfounded claims of MSG safety

From 1968 until approximately 1980, Ajinomoto mounted a vigorous attack to refute the studies that demonstrated MSG-induced brain damage. Beginning in 1968 and throughout the 1970s, glutamate-industry agents mounted alleged replications of independently done glutamate-induced brain damage studies, but their procedures were different enough to guarantee that toxic doses had not been administered, and/or that all evidence that neurons had died would be obscured. Industry-sponsored researchers claimed to be replicating studies, but did not do so (5).

When it could no longer be denied that animal studies showed that MSG caused brain damage in infant animals – when researchers were using models of MSG-induced obesity to study abnormalities associated with excess glutamate — industry interests decreed that studies done on animals did not reflect the human condition and were, therefore, meaningless.

Industry-sponsored human studies followed in the 1980s. None were studies of brain damage.

III. Availability of sufficient potentially excitotoxic manufactured/processed free glutamate (MfG) in food and elsewhere to cause MfG to become excitotoxic (to kill brain cells)

Evidence of MSG-induced neonatal brain damage has not changed in the last four decades, but availability of sufficient glutamate in the U.S. food supply to cause that glutamate to become excitotoxic has.

Prior to 1957, the date that Ajinomoto reformulated MSG, the amount of free glutamate in the average diet had been unremarkable. But in 1957 production of the free glutamate that makes up the excitotoxic ingredient in MSG changed from extraction of glutamate from a protein source, a slow and costly method, to a method of bacterial fermentation which enabled virtually unlimited production of free glutamate and MSG (7), and the large amounts of glutamate needed to cause excitotoxicity became widely available.

Shortly thereafter, food manufacturers found that profits could be increased by producing other flavor-enhancing additives that contained free glutamate. Over the next two decades, the marketplace became flooded with manufactured/processed free glutamate in ingredients such as hydrolyzed proteins, yeast extracts, maltodextrin, soy protein isolate, and MSG (8). And ingredients that contained free glutamate became readily accessible.

There are no data on the amount of excitotoxic material in food. Analyses from Olney’s lab and others provided some insight into amounts of MSG in processed foods in the 1980s and 1990s (half a gram of MSG in certain canned soups, for example); and according to anecdotal reports from MSG-sensitive people, that would be enough to trigger an asthma attack or a migraine headache in some MSG-sensitive people. Reports from MSG-sensitive consumers also suggest that the amount of MfG in a single serving of processed food might be similar to that found in various cans of soup. None of this, however, speaks to the amount of MfG needed to produce either brain damage or adverse reactions.

Important to remember is the fact that it is not the amount of MfG in any one product that is pertinent to determining if there is sufficient MfG available to cause neonatal brain damage or adverse reactions. To cause neonatal brain damage, it is the amount of MfG consumed by a pregnant or lactating subject and passed to fetus and/or neonate that is relevant to determination of excitotoxicity.

IV. MSG-induced adverse reactions

There are few published reports of MSG-induced human adverse reactions. Funding for studies of the safety of MSG comes primarily from the glutamate industry, and only those industry-sponsored studies with negative results have been published.

Some years ago, Samuels compiled a list of studies wherein adverse reactions to MSG were noted (1-4, 175, 179-236). The article can be accessed at .

No attempt has been made to identify all of the more recent studies. A PubMed search for “MSG-induced OR monosodium glutamate-induced AND toxicity” done on May 5, 2020 elicited 93 citations (

V. Warnings

By 1980, glutamate-associated disorders such as headaches, asthma, diabetes, muscle pain, atrial fibrillation, ischemia, trauma, seizures, stroke, Alzheimer’s disease, amyotrophic lateral sclerosis (ALS), Huntington’s disease, Parkinson’s disease, depression, multiple sclerosis, schizophrenia, obsessive-compulsive disorder (OCD), epilepsy, addiction, attention-deficit/hyperactivity disorder (ADHD), frontotemporal dementia, and autism were on the rise.

By and large, the glutamate in question was, and still is, glutamate from endogenous sources. The possible toxicity of glutamate from exogenous sources such as glutamate-containing flavor-enhancers has generally not being considered. But Olney and a few others have suggested that ingestion of free glutamate might play a role in producing the excess amounts of glutamate needed for endogenous glutamate to become excitotoxic (34-53).

VI. Suppression of information

The request to which I am responding was for quality peer-reviewed research that contradicts your positions. A list of those studies has been submitted with this letter.

Let me just mention that the videos you offered as the information on MSG safety came, directly or indirectly, from the glutamate-industry. The “update on MSG” is delivered by an unidentified person (as is “Is MSG Bad for You”) who speaks of scientific consensus and decades of research. The “scientific consensus” mentioned is the consensus of people brought together by Ajinomoto for the purpose of concluding that MSG is harmless. The “decades of research” were discussed earlier in this letter as negative studies that failed to demonstrate a clear and consistent relationship between MSG and adverse reactions. “Is MSG bad for you?” speaks only of consensus meetings. No sound scientific studies there. I would be happy to send you a link by email to my early notes on Williams and Woessner and on “the consensus meeting” should you have interest.

Equally important for you to appreciate are the studies that have been rigged by glutamate industry interests, and the tactics that have been used by glutamate-industry interests to promote sales of MSG. A 1999 published, peer-reviewed article speaks to that subject (101).

In addition, I have taken the liberty of enclosing the link to a file from my webpage titled “Designed for Deception.” Among other things, it details the tactics that Ajinomoto has used to rig its double-blind studies. (They stopped doing double-blind studies after we exposed the fact that they were lacing what they called “placebos” with aspartic acid, the excitotoxic amino acid used in aspartame. Aspartame and free aspartic acid cause the same brain damage and adverse reactions as those caused by MSG and free glutamic acid (32, 46, 102).

VI. Suppression of information

The food industry helped get us where we are today. Now it’s profiteering on the results.

It’s something we’ve all heard before: Those at the highest risk of a severe reaction or death from a COVID-19 infection have an “underlying condition.”

And the top “condition,” as it turns out, is obesity. The Centers for Disease Control and Prevention released results from a study last month that examined those who were hospitalized due to COVID-19 in 99 counties across 14 states, and the results are staggering. Close to 60 percent in the 18-49 group involved those who were obese. For people 50-64, obesity was the underlying condition for nearly 50 percent who were hit hard, along with 41 percent of patients 65 and over.

While it’s hardly news that obesity, especially in America, is so widespread it’s now referred to as an “epidemic,” many experts seem to have just realized that the food industry has been working for a very long time to make its ultra-processed foods considered normal eating options for breakfast, lunch and dinner.

Some, such as UK cardiologist Dr. Aseem Malhotra, are going so far as to say that if health authorities don’t warn citizens to change the way they eat, it would constitute “negligence and ignorance.” 

Professor Tim Spector, an expert in genetic epidemiology at King’s College in London remarked that “Obesity and poor diet is emerging as one of the biggest risk factors for a severe response to COVID-19 infection that can no longer be ignored.”

And Professor Robert Listig, from the University of California commented on the CDC report by saying that “ultra-processed food sets you up for inflammation,” which is something COVID-19 is “happy to exploit.”

But as they say, talk is cheap. What isn’t, however, is how much money Big Food spends to make sure that these stockpiles of processed products that have undermined our health so much keep on selling. And despite what that CDC report revealed, ultra-processed, obesity-spawning foods are flying off the shelves faster than ever before.

A distressing comfort

At one time, comfort foods used to constitute mom’s mac and cheese, homemade mashed potatoes or a batch of oatmeal raisin cookies fresh out of the oven. Now it appears that our eating habits have deteriorated to the point where many of the hundreds of New York Times readers commenting on an article titled “‘I Just Need the Comfort’: Processed Foods Make a Pandemic Comeback,” are arguing the vital need to consume unlimited amounts of Velveeta, canned pasta and “cheese” that comes from a can.

For Big Food, it’s likely a sales dream come true.

General Mills reported that sales are up “across-the-board” during the last month, including packaged dinner mixes such as Hamburger Helper, described by a spokesman as a “simple and delicious meal.”

Conagra Brands saw a 50 percent increase for products such as Slim Jim and Chef Boyardee canned pastas during March. Kraft/Heinz now needs to keep some factories working three shifts just to keep cranking out enough boxed macaroni and cheese, with Campbell’s soup sales jumping almost 60 percent from where they were a year ago.

And Impossible Foods, which makes the additive filled, ultra-processed fake meat called the “Impossible Burger,” has been able to use this pandemic to get its products into 777 more grocery stores in the U.S.

If, as many experts are saying, the threat posed by COVID-19 will be with us for quite a while — even gaining tragic traction in the fall — now is the time to make sure you’re in fighting shape. And judging from the CDC’s research, it appears that can best be started right in your kitchen.
