MSG

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.

While MSG's benefits to the food industry are quite clear, this food additive could be slowly and silently doing major damage to your health.

You may remember when the MSG powder called "Accent" first hit the U.S. market. Well, it was many decades prior to this, in 1908, that monosodium glutamate was invented. The inventor was Kikunae Ikeda, a Japanese man who identified the natural flavor enhancing substance of seaweed.

Taking a hint from this substance, they were able to create the man-made additive MSG, and he and a partner went on to form Ajinomoto, which is now the world's largest producer of MSG (and interestingly also a drug manufacturer). 2

Chemically speaking, MSG is approximately 78 percent free glutamic acid, 21 percent sodium, and up to 1 percent contaminants.3

It's a misconception that MSG is a flavor or "meat tenderizer." In reality, MSG has very little taste at all, yet when you eat MSG, you think the food you're eating has more protein and tastes better. It does this by tricking your tongue, using a little-known fifth basic taste: umami.

Umami is the taste of glutamate, which is a savory flavor found in many Japanese foods, bacon and also in the toxic food additive MSG. It is because of umami that foods with MSG taste heartier, more robust and generally better to a lot of people than foods without it.

The ingredient didn't become widespread in the United States until after World War II, when the U.S. military realized Japanese rations were much tastier than the U.S. versions because of MSG.

In 1959, the U.S. Food and Drug Administration labeled MSG as "Generally Recognized as Safe" (GRAS), and it has remained that way ever since. Yet, it was a telling sign when just 10 years later a condition known as "Chinese Restaurant Syndrome" entered the medical literature, describing the numerous side effects, from numbness to heart palpitations, that people experienced after eating MSG.

Today that syndrome is more appropriately called "MSG Symptom Complex," which the Food and Drug Administration (FDA) identifies as "short-term reactions" to MSG. More on those "reactions" to come.
Why MSG is so Dangerous

One of the best overviews of the very real dangers of MSG comes from Dr. Russell Blaylock, a board-certified neurosurgeon and author of "Excitotoxins: The Taste that Kills." In it he explains that MSG is an excitotoxin, which means it overexcites your cells to the point of damage or death, causing brain damage to varying degrees -- and potentially even triggering or worsening learning disabilities, Alzheimer's disease, Parkinson's disease, Lou Gehrig's disease and more.

Part of the problem also is that free glutamic acid is the same neurotransmitter that your brain, nervous system, eyes, pancreas and other organs use to initiate certain processes in your body.4 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."5

Although the FDA continues to claim that consuming MSG in food does not cause these ill effects, many other experts say otherwise.

According to Dr. Blaylock, numerous glutamate receptors have been found both within your heart's electrical conduction system and the heart muscle itself. This can be damaging to your heart, and may even explain the sudden deaths sometimes seen among young athletes.

"When an excess of food-borne excitotoxins, such as MSG, hydrolyzed protein soy protein isolate and concentrate, natural flavoring, sodium caseinate and aspartate from aspartame, are consumed, these glutamate receptors are over-stimulated, producing cardiac arrhythmias.

When magnesium stores are low, as we see in athletes, the glutamate receptors are so sensitive that even low levels of these excitotoxins can result in cardiac arrhythmias and death." 6

Many other adverse effects have also been linked to regular consumption of MSG, including:

Obesity
Eye damage
Headaches
Fatigue and disorientation
Depression

Further, even the FDA admits that "short-term reactions" known as MSG Symptom Complex can occur in certain groups of people, namely those who have eaten "large doses" of MSG or those who have asthma.7

According to the FDA, MSG Symptom Complex can involve symptoms such as:

Numbness
Burning sensation
Tingling
Facial pressure or tightness
Chest pain or difficulty breathing
Headache
Nausea
Rapid heartbeat
Drowsiness
Weakness

No one knows for sure just how many people may be "sensitive" to MSG, but studies from the 1970s suggested that 25 percent to 30 percent of the U.S. population was intolerant of MSG -- at levels then found in food. Since the use of MSG has expanded dramatically since that time, it's been estimated that up to 40 percent of the population may be impacted.8
How to Determine if MSG is in Your Food

Food manufacturers are not stupid, and they've caught on to the fact that people like you want to avoid eating this nasty food additive. As a result, do you think they responded by removing MSG from their products? Well, a few may have, but most of them just tried to "clean" their labels. In other words, they tried to hide the fact that MSG is an ingredient.How do they do this? By using names that you would never associate with MSG.

You see, it's required by the FDA that food manufacturers list the ingredient "monosodium glutamate" on food labels, but they do not have to label ingredients that contain free glutamic acid, even though it's the main component of MSG.There are over 40 labeled ingredients that contain glutamic acid,9 but you'd never know it just from their names alone. Further, in some foods glutamic acid is formed during processing and, again, food labels give you no way of knowing for sure.
Tips for Keeping MSG Out of Your Diet

In general, if a food is processed you can assume it contains MSG (or one of its pseudo-ingredients). So if you stick to a whole, fresh foods diet, you can pretty much guarantee that you'll avoid this toxin.The other place where you'll need to watch out for MSG is in restaurants. You can ask your server which menu items are MSG-free, and request that no MSG be added to your meal, but of course the only place where you can be entirely sure of what's added to your food is in your own kitchen. To be on the safe side, you should also know what ingredients to watch out for on packaged foods. Here is a list of ingredients that ALWAYS contain MSG:

Autolyzed Yeast


Calcium Caseinate


Gelatin

Glutamate


Glutamic Acid


Hydrolyzed Protein

Monopotassium Glutamate


Monosodium Glutamate


Sodium Caseinate

Textured Protein


Yeast Extract


Yeast Food

Yeast Nutrient


These ingredients OFTEN contain MSG or create MSG during processing:10

Flavors and Flavorings


Seasonings


Natural Flavors and Flavorings


Natural Pork Flavoring


Natural Beef Flavoring

Natural Chicken Flavoring


Soy Sauce


Soy Protein Isolate


Soy Protein


Bouillon

Stock


Broth


Malt Extract


Malt Flavoring


Barley Malt

Anything Enzyme Modified


Carrageenan


Maltodextrin


Pectin


Enzymes

Protease


Corn Starch


Citric Acid


Powdered Milk


Anything Protein Fortified

Anything Ultra-Pasteurized


So if you do eat processed foods, please remember to be on the lookout for these many hidden names for MSG.
Choosing to be MSG-Free

Making a decision to avoid MSG in your diet as much as possible is a wise choice for nearly everyone. Admittedly, it does take a bit more planning and time in the kitchen to prepare food at home, using fresh, locally grown ingredients. But knowing that your food is pure and free of toxic additives like MSG will make it well worth it. more

Monosodium glutamate (MSG) is a flavor enhancer commonly added to Chinese food more  
I have been eating food with MSG in correct proportion for last thirty years! Nothing happened so far. I would like to give an example of one market research done in USA. In that they called people claiming to be suffering due to MSG and divided them in two sections. one group was served food in a hotel and was told that the food contains MSG while it actually did not have it. Other group was served food and was told that it does not contain MSG while it actually had MSG. On finding it was found that so many complained for MSG allergy while actually the food they ate was not having it. on the other side the other group did not complained of any MSG allergy even though they had eaten food with MSG!. This test was conducted several times on different groups and finally it showed that allergy due to MSG is only imaginary and there is no truth in it. more  
There is a lot of misgiving just like we see in this comment. Nobody takes anything more than necessary. And if we take any food item more than necessary it is bad for health. There is no sense in creating suspicious situation and spread wrong notions. All food should be taken in the correct proportion; principle of limits applies everywhere. MSG is a very good condiment and helps eat food better. more
