Monosodium Glutamate: Its Code Words & Ties To Weight Gain, Seizures & Sudden Death

I used to think monosodium glutamate was just a Chinese restaurant additive, but the Truth In Labeling site opened my eyes with all the other ‘names’ it can go by in ingredient lists. It was certainly another piece of the puzzle in discovering why my child was reacting to certain foods.

What I didn’t know, is that there are more than 40 different ingredients that contain the chemical in MSG (processed free glutamic acid) and cause reactions in reactive people (whether mildly or seriously). 

MSG is more than just a seasoning like salt and pepper, it actually enhances the flavor of foods, making processed meats and frozen dinners taste fresher and smell better, salad dressings more tasty, and canned foods less tinny.

The following list of ingredients that contain processed free glutamic acid has been compiled over the last 20 years from consumers’ reports of adverse reactions and information provided by manufacturers and food technologists.

___________________________________________________________

Names of ingredients that always contain processed free glutamic acid: Glutamic acid (E 620)2,  Glutamate (E 620) Monosodium glutamate (E 621) Monopotassium glutamate (E 622) Calcium glutamate (E 623) Monoammonium glutamate (E 624) Magnesium glutamate (E 625) 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’ or ‘protein fortified’ Vetsin Ajinomoto Umami

Names of ingredients that often contain or produce processed free glutamic acid: Carrageenan (E 407) Bouillon and broth Stock Any “flavors” or ‘flavoring’ Maltodextrin Citric acid, Citrate (E 330) Anything ‘ultra-pasteurized’ Barley malt Pectin (E 440) Protease Anything ‘enzyme modified’ Anything containing ‘enzymes’ Malt extract Soy sauce Soy sauce extract Anything ‘protein fortified’ Seasonings (1) Glutamic acid found in unadulterated protein does not cause adverse reactions.   To cause adverse reactions,   the glutamic acid must have been processed/manufactured or come from protein that has been fermented.

The following are ingredients suspected  of containing or creating sufficient processed free glutamic acid to serve as MSG-reaction triggers in HIGHLY SENSITIVE people:       Corn starch Corn syrup Modified food starch Lipolyzed butter fat Dextrose Rice syrup Brown rice syrup Milk powder Reduced fat milk                     (skim;  1%; 2%) Most things low fat              or no fat anything Enriched anything Vitamin enriched (2) E numbers are use in Europe in place of food additive names.

As little as 1/10th of a tsp of monosodium glutamate (MSG) can give a severe reaction, and reactions can be dose related: the more you consume the greater chance of the reaction.

Some common side effects include the following (source):

• tachycardia and other arrhythmia
• heart attacks
• asthma
• headaches
• mood swings
• facial swelling
• swelling in the joints
• marked obesity
• tightness in the chest
• joint pain
• sterility in females
• In laboratory experiments, every species of animal fed MSG developed brain lesions and infant animals were especially susceptible, as they had not developed an effective blood-brain barrier.

MSG’s Connection to:

Increased Body Weight

Many studies link MSG to the development of obesity, and children are especially susceptible. The Ukrainian National Academy of Sciences recently discovered that MSG given to newborn mice increases their body weight by 7.9%. It also causes an increase in body mass index and fat mass, as well as significant increases in total cholesterol, triglycerides, VLDL, and LDL (both types of “bad” cholesterol). Additional studies show that maternal exposure to MSG during pregnancy leads to childhood obesity, behavioral changes and convulsions. Research shows that increases in weight, body fat, and obesity also occur in adults who consume MSG.

Also, Leptin becomes unrecognizable to the brain. This chemical messenger is normally released by fat cells, and then travels to the brain to deliver the signal to stop eating. However, in people who consume MSG, receptors in the brain become incapable of receiving this signal, despite its increased production by fat cells. This leads to an increased appetite.

Seizures and Cellular Damage to Brain

Monosodium glutamate is an excitotoxin that reacts with specialized receptors (neurons) in the brain in such a way as to lead to the destruction of certain types of brain cells. Humans lack a blood-brain barrier in the hypothalamus, which allows these excitotoxins to enter the brain and cause damage.

MSG can create a lesion in the hypothalamus that correlates with abnormal development, including obesity, short stature, and male/female infertility. MSG has also been shown to cause migraine headaches and depression.

Rigorous animal studies raise questions about possible dangers to infants and preborn babies including alteration in blood-brain barrier permeability, convulsions and seizures during infancy and later in life.

Even the FDA states:

“Studies have shown that the body uses glutamate, an amino acid, as a nerve impulse transmitter in the brain and that there are glutamate-responsive tissues in other parts of the body, as well.

Abnormal function of glutamate receptors has been linked with certain neurological diseases, such as Alzheimer’s disease and Huntington’s chorea. Injections of glutamate in laboratory animals have resulted in damage to nerve cells in the brain.” [1]
