Your Daily Additives – MSG

It is extremely convenient this additive has been around and patented since 1909 and I believe it has been one of the most used and most denied chemical food agents of all. Yet among all the others toxic G.R.A.S. substances I’ve researched, none have caused so much controversy for me. I have found toxic data reports for everything I’ve looked for except MSG.

But, I have to ask: If you know the food you’re consuming is produced with corrosive and toxic chemicals, would you attempt to avoid it?


General Research:

Monosodium Glutamate

 Also known as:

Natural Flavor, Glutamic Acid, Glutamate, Monopotassium Glutamate, Calcium Glutamate, Monoammonium Glutamate, Magnesium Glutamate, Natrium Glutamate, Yeast Extract, Anything “Hydrolyzed”, Any “Hydrolyzed Protein”, Calcium Caseinate, Sodium Caseinate, Yeast Food, Yeast Nutrient, Autolyzed Yeast, Gelatin, Textured Protein, Soy Protein, Soy Protein Concentrate, Soy Protein Isolate, Whey Protein, Whey Protein Concentrate, Whey Protein Isolate, Anything “…Protein”, Vetsin, Ajinomoto

Names of ingredients that often contain or produce processed free glutamic acid

Carrageenan, Bouillon and Broth, Stock, Any “Flavors” or “Flavoring”, Maltodextrin, Citric Acid, Citrate, Anything “Ultra-Pasteurized”, Barley Malt, Pectin, Protease, Anything “Enzyme Modified”, Anything containing “Enzymes”, Malt Extract, Soy Sauce, Soy Sauce Extract, Anything “Protein Fortified”, Anything “Fermented”, Seasonings


“After a single dose of MSG, Doctors discovered that specialized cells in a critical area of the animal’s brain, the hypothalamus, had been destroyed.”

Millions of babies all over the world were eating baby foods containing large amounts of MSG and hydrolyzed vegetable protein (a compound which contains three excitotoxins).



-Protein class of substances that damage neurons through paroxysmal over activity. They are toxins that bind to certain receptors (e.g., certain glutamate receptors) and may cause neuronal cell death.-

Samuels (1999) reported that MSG is a neurotoxic agent i.e. causing damage to brain cells, retinal degeneration, leading to many endocrine disorders and causes renal damage.

The best known excitotoxins are the excitatory amino acids that can produce lesions in the CNS (Central Nervous System) similar to those of Huntingdon’s chorea or Alzheimer’s disease. Excitotoxicity is thought to contribute to neuronal cell death associated with stroke.

Rats given free access to MSG and water showed a high preference (93-97%) for the MSG solution, regardless of the diet they consumed

Rats treated with MSG showed morphological and morphometric changes as decrease in testicular weight, decrease in tubular diameter, reduction in germinal epithelium height, decrease in the spermatic count and abnormalities of sperms morphology.

Many studies reported the implication of (MSG) in cases of male infertility as it causes testicular hemorrhage, degeneration and alteration of sperm cell population and morphology


(Processing of MSG)

(These are only a few of the many steps of processing)


Monosodium Glutamate is processed with Metylthiopropionaldehyde and Sodium Hydroxide which both are highly corrosive and toxic.

“After the concentration of DAP had reached a maximum in the presence of the first mutant, the first mutant was removed and another E. coli strain was added.”

“The crude, crystalline glutamic acid is first suspended in water and then dissolved, neutralized and converted to the monosodium salt by the addition of Sodium Hydroxide.

“The acidic filtrate was then adjusted by addition of Sodium Hydroxide or Ammonia”

These products are carbon oxides, nitrogen oxides and some metallic oxides.

Burning may produce carbon monoxide, carbon dioxide or nitrogen oxides.

WHMIS (Canada): CLASS D-2A: Material causing other toxic effects (VERY TOXIC).


Sodium Hydroxide

caustic soda

(Is this in your kitchen?)

Potential Acute Health Effects:

Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact (irritant, corrosive), of ingestion, of inhalation.

The amount of tissue damage depends on length of contact.

Eye contact can result in corneal damage or blindness.  Inflammation of the eye is characterized by redness, watering, and itching.

Skin contact can produce inflammation and blistering. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering

Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking, unconsciousness or death.

Potential Chronic Health Effects:

MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells.

The substance may be toxic to mucous membranes, upper respiratory tract, skin, eyes. Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.

Slightly explosive in presence of heat.

Incompatible materials, moisture, moist air

Large Spill: Corrosive solid. Stop leak if without risk Do not touch spilled material Keep container dry. Do not breathe dust. Never add water to this product.

If you feel unwell, seek medical attention and show the label when possible. Avoid contact with skin and eyes.

Keep away from incompatibles such as oxidizing agents, reducing agents, metals, acids, alkalis, moisture.

May cause damage to the following organs: mucous membranes, upper respiratory tract, skin, eyes.

Special Remarks on Chronic Effects on Humans:

May affect genetic material. Investigation as a mutagen (cytogenetic analysis)

For two years I've thoroughly enjoyed researching the food additives "scientests" produce and put into all processed food. Also how the FDA classifies them as G.R.A.S. (Generally Recognized As Safe) With about 95% of the research I've done over the last two years the actual science, toxicity reports, manufacturing processes and pure technical aspect of it suggests otherwise.

When you see something that is "hazardous by definition", toxic, poisonous or corrosive and it's in the food you're eating, you would surely have to stop, think and ask, "That's going to go in me. Wait... It passes through the placental barrier? It decreases the testicular weight in mice? It's produced with volvano ash? It's processed with asbestos and krypton gas?"

Now, my main argument is this: If you know the food additive is toxic, corrosive or hazardous by definition, if it requires flammable or corrosive DOT stickers while transporting, if it has saftey precautions, spill procedures and you must wear suitable protective clothing while handling... Can you even assume it's safe to eat?

Irregardless of the exposure limits, the actual amount in food itself, how many regulations and standards there are or how low the toxicity may be... It is the general principle that the additives are still put in the foods you eat on a daily basis. I personally don't believe that when a tomato is dropped you have to evacuate the area and seal off the exits. Because that is exactly the procedure for some of the chemcial agents the FDA allowed in food.
