MSG: Delicious Seasoning Or Drug And Poison?

MSG: Delicious Seasoning Or Drug And Poison? | monosodium-glutamate | General Health Special Interests Toxins


Poor food quality is a growing problem in industrialized countries increasingly focused on the quantitative dimension of food production, both in terms of the sheer volume of food produced, as well as the revenue and profit generated. In the United States, for instance, consumers do not even have the right to know what is in their food, e.g. genetically modified ingredients are not labeled by default; the use of paint pigment (titanium dioxide) as a “manufacturing aid” in milk, not required to be listed as an ingredient on the label, etc, and raw human sewage and factory-farmed animal waste, as well as petroleum and coal byproducts, are all considered fair game as a growing medium in USDA-approved conventional farming practices.


Given these deteriorating market conditions, our bodies, which spent eons evolving complex sensorial and cognitive pathways to determine whether something was good, or bad, based on appearance, taste, smell, etc., are increasingly being chemically manipulated through food science trickery. And as the food in its unadulterated state becomes more and more unappetizing, if not clearly disgusting, the slick marketing and associated nutritional disinformation becomes less and less effective on the consumer.  Enter MSG, a virtual miracle worker when it comes to turning disgusting into delicious….


Turning Yucky To Yummy With The MSG Sleight of Hand


Monosodium glutamate (MSG) is a commonly used “flavor enhancer,” and so powerfully so that (hyperbole permitting) you could spray it on roadkill and it would taste good. This omnipresent ingredient in modern mass market food takes advantage of our biologically hard-wired taste receptors, and makes it very hard to stop eating the foods “seasoned” with this ingredient. In fact, it is doubtful that without the MSG trick many of these mass market processed foods would be palatable enough to maintain their status as economically viable commodities. Here are some of its many disguises on food labels….

Technically MSG is the sodium salt of glutamic acid, a naturally occurring non-essential amino acid. Glutamic rich foods include wheat, dairy, corn, soy, seafood, etc. (Foods Highest In Glutamic Acid). The “YUMMY!” sensation that occurs immediately after ingesting a MSG (or various synonyms, e.g. hydrolyzed protein, autolyzed yeast) laced morsel the Japanese call umami (meaning: savoriness) and is considered one of five basic tastes.


The problem is that when one isolates out of a complex food a singular amino acid, and increase the concentration to unnatural proportions (and without the hundreds of checks and balances Nature provides in the context of a whole food), glutamic acid can have devastating health effects, not the least of which is the generation of an insatiable appetite for more of the very same chemical stimulating the craving — a vicious, self-amplifying cycle!



Monosodium Glutamate Causes Excitotoxicity


One of the primary adverse effects associated with excess glutamic acid is excitotoxicity, a form of neurotoxicity where neurons are stimulated to the point of cell death. Repeated excitotoxic events can result in neuronal lesions and loss of cognitive function.


While there are a number of natural substances that mitigate this type of excitotoxicity, the best choice is to reduce the consumption of glutamic acid (as well as its “twin” excitotoxic non-essential amino acid aspartic acid) rich foods, especially if there is a pre-existing neurological condition such as migraines, epilepsy or multiple sclerosis, to name but a few.  John Symes has written an excellent document on the benefits of the Glutamic and Aspartic Acid Reduced Diet (GARD Diet) here.


More Than An Excitotoxic Agent: An Endocrine Disruptor


Recently Dr. Mercola featured the connection between MSG and obesity.  While excessive food cravings caused by MSG’s taste-enhancing effects figure into this relationship, research from the US National Library of Medicine indexed on our site shows that MSG may directly cause hypothalamic lesions that result in elevated insulin, insulin resistance and leptin resistance (leptin suppresses appetite).


It is becoming clear that MSG can no longer be considered simply a “flavor enhancer” but an intrinsically harmful chemical with endocrine disruptive properties. Research we have collected shows that MSG actively contributes to metabolic syndrome, obesity, fatty liver, dysregulated blood lipids, as well as a wide range of neurological problems.


In a nutshell, monosodium glutamate (MSG) contributes to illness in two distinct ways:


1) It makes food that is bad for us taste really, really, really good, in essence compromising our health by tricking our taste buds and intuition into eating things that are intrinsically harmful, or harmful when eaten excessively.


2) It is a toxic chemical that directly damages neurological tissue through its excitotoxic properties, as well as inducing a generalized endocrine disruption throughout the body known as “metabolic syndrome,” the symptoms of which include hypertension, insulin resistance, elevated blood lipids and/or elevated blood sugar.[1] [2] [3]

MSG Proven Highly Toxic: 1 Dose Causes Headache In Healthy Subjects

MSG Proven Highly Toxic: 1 Dose Causes Headache In Healthy Subjects | msg_headache | General Health Toxins


Found everywhere as an additive in your food, research has uncovered that this “flavor enhancer” is extremely toxic, causing a battery of adverse health effects within normal dietary ranges.


A study published in the Journal of Headache Pain reveals that a single intake of monosodium glutamate (MSG) produces headache in the majority of healthy subjects tested.[i]



The researchers conducted a double-blinded, placebo-controlled, crossover study to examine the effect of repeated MSG intake on the following:


  • Spontaneous pain

  • Mechanical sensitivity of masticatory muscles (the four muscles that move the jaw laterally)

  • Side effects

  • Blood pressure

The study method was described as follows:



“Fourteen healthy subjects participated in 5 daily sessions for one week of MSG intake (150 mg/kg) or placebo (24 mg/kg NaCl) (randomized, double-blinded). Spontaneous pain, pressure pain thresholds and tolerance levels for the masseter and temporalis muscles, side effects, and blood pressure were evaluated before and 15, 30, and 50 min after MSG intake. Whole saliva samples were taken before and 30 min after MSG intake to assess glutamate concentrations.”



The results were as follows:


  • Headache occurred in 8/14 subjects during MSG and 2/14 during placebo.

  • Salivary glutamate concentrations on Day 5 were elevated significantly (P < 0.05).

  • Pressure pain thresholds in masseter muscle were reduced (i.e. pain increased) by MSG on Day 2 and 5 (P < 0.05).

  • Blood pressure was significantly elevated after MSG (P < 0.040).

  • Tolerance did not develop over 5 days of MSG intake.

Also, a wide range of side effects were observed to occur in much greater frequency in the MSG group, including:


  • Sore Jaw

  • Nausea

  • Fatigue

  • Headache

  • Stomach Ache

  • Dizziness

  • Chest Pressure

Discussion


This study has profound implications, insofar as the majority of packaged and prepared foods on the market today have either monosodium glutamate added, or a glutamate rich ‘food concentrate’ intended to model its flavor-enhancing effects, e.g. “hydrolyzed soy protein,” “yeast extract,” etc. It is therefore nearly impossible to avoid it, unless you are eating a whole food based diet, or one where you are preparing your foods from scratch. For those suffering from the battery of health complaints listed above, MSG avoidance should be a vital part of your strategy to improve your health through diet.


This study also has profound implications for the treatment of Temporomandibular Disorders (TMD).  According to the study, TMD affects approximately 10% of the population, [ii] [iii] with the chief symptom leading the patient to seek medical attention being pain in the temporomandibular joint and/or masticatory muscles.  Interestingly, 70% of TMD sufferers report masticatory muscle pain and are described as suffering from myofascial TMD, [iv] despite the fact that there is little evidence of ongoing pathological change in masticatory muscles. It has been hypothesized that dietary triggers might aggravate craniofacial pain conditions, but until now little to no research has been conducted on their link with MSG. Because the doses used in the study (150 mg/kg) are within the daily total dietary ranges of glutamate consumption (50–200 mg/kg/day),[v] it is likely that the high prevalence of TMD without obvious pathological lesions within glutamate consuming populations may be due to MSG.


MSG Has A Broad Range of Adverse Health Effects


MSG is a neurotoxic and endocrine disruptive substance, linked to over a dozen health conditions. You can peruse the first-hand published research on our problem substances database: monosodium glutamate. In a previous article, “MSG: Drug, Poison or Flavor Enhancer,” we focused on the excitotoxic mechanism by which it ‘enhances flavor’ in a drug-like fashion, while at the same time damaging neurons, in addition to its ability to contribute to metabolic syndrome: a cluster of pathologies including insulin resistance, weight gain, altered blood lipid profiles, and hypertension. If it is so harmful, why does everyone use it? Because it makes food taste better, and causes a profound craving for more, in a vicious not that different from an illicit drug.
