Monosodium glutamate, commonly known as MSG, was thought of as a "miracle food enhancer" when it was first introduced to the public over five decades ago.
More than just a seasoning like salt and pepper, MSG could actually enhance the flavors of foods, making processed meats and frozen dinners taste fresher and smell better, salad dressings more tasty, and canned foods less tinny.
It wasn't until people started having side effects after eating foods with MSG that some began to question whether this miracle flavoring was too good to be true. Today, many more question its safety, but others insist it's safe.
How Much MSG are Americans Eating?
Americans associate MSG with Chinese food. In fact, MSG Symptom Complex, which the Food and Drug Administration (FDA) identifies as "short-term reactions" to MSG, was for some time (unfairly) referred to in the United States as "Chinese Restaurant Syndrome."
But MSG is in many more foods than Chinese food, and is listed under many other names than MSG. So while many Americans are aware that MSG has been linked to some negative side effects, or have experienced them personally, and believe they are avoiding it in their diets, many have been misled.
Food manufacturers, who realize that many people would prefer NOT to have MSG in their food, have adapted by using so-called "clean labels." These ingredient labels hide MSG under names that consumers won't recognize, such as hydrolyzed soy protein.
Some manufacturers have also gone so far as to list "No MSG," "No Added MSG," or "No MSG Added" on product labels when MSG is still present, but exists only as a constituent in another ingredient!
MSG is Always In:
* Autolyzed yeast
* Calcium caseinate
* Gelatin
* Glutamate
* Glutamic acid
* Hydrolyzed protein
* Monopotassium glutamate
* Monosodium glutamate
* Sodium caseinate
* Textured protein
* Yeast extract
* Yeast food
* Yeast Nutrient
MSG is Often In:
* Barley Malt
* Bouillon
* Broth
* Carrageenan
* Enzyme-modified substances
* Flavoring
* Flavors
* Malt Extract
* Malt flavoring
* Maltodextrin
* Natural flavor/flavorings
* Natural pork/beef/chicken flavoring
* Pectin
* Protein-fortified substances
* Seasonings
* Soy protein
* Soy protein isolate or concentrate
* Soy sauce
* Soy sauce extract
* Stock
* Vegetable gum
* Whey protein
* Whey protein isolate or concentrate
What Does the Government Say?
The Federation of American Societies for Experimental Biology (FASEB), a group of scientists the FDA asked to review the safety of glutamate, released a report in 1995 that found the following:
* When consumed at usual levels, MSG is safe for the general population.
* No evidence of any connection between MSG and serious long-term reactions.
* No evidence linking dietary MSG or glutamate to Alzheimer's disease, Huntington's disease, or any other long-term or chronic diseases.
* No evidence suggesting that dietary MSG or glutamate causes brain lesions or damage to nerve cells in humans.
However, the study did find that MSG Symptom Complex did occur in some people, particularly those who ate a large dose of MSG and those with severe asthma. According to the FDA, MSG Symptom Complex can result in:
* Numbness
* Burning sensation
* Tingling
* Facial pressure or tightness
* Chest pain
* Headache
* Nausea
* Rapid heartbeat
* Drowsiness
* Weakness
* Difficulty breathing for asthmatics
Estimates of just how many Americans are sensitive to MSG vary widely: from 1.8 percent to 50 percent of the population may be affected. However, these estimates may be conservative. Symptoms related to MSG may present immediately or several hours after eating a food, so attributing them to MSG can be difficult.
In terms of labeling requirements, the FDA says that "monosodium glutamate" must be listed on the label only if MSG is added to a food. However, it's misleading for a manufacturer to list "No MSG," or "No Added MSG" on foods if sources of free glutamates, like hydrolyzed protein, exist, they say. Further, items listed as "flavors," "natural flavors," or "flavorings" may not include MSG, hydrolyzed proteins or autolyzed yeast.
The Other Side
Other experts are not so convinced of MSG's safety. For instance, Dr. Russell Blaylock, an author and neurosurgeon, recently explained a link between sudden cardiac death, particularly in athletes, and excitotoxic damage caused by food additives like MSG and artificial sweeteners. Excitotoxins are, according to Dr. Blaylock, "A group of excitatory amino acids that can cause sensitive neurons to die."
Said Dr. Blaylock:
"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."
Further, many consumers have personally experienced the ill effects of MSG, which leave them with a headache, nausea or vomiting after eating MSG-containing foods.
Said Cathy Evans Wisner in her article "The MSG Myth," "I know from personal experience that the chemical is not as harmless as vinegar or salt. When I ingest a fair amount of MSG, I immediately have nausea, stomach cramps, "spaciness," heart palpitations and a "pins-and-needles" headache, followed the next day by lethargy and overall weakness."
Headaches are one of the most commonly reported side effects of MSG, which may occur because it can increase blood flow to the brain. According to Ann Turner, director of the Migraine Action Association, "Food additives can be triggers [for headaches]. MSG, although still not fully understood, may be a culprit ? "
Which Foods Contain MSG?
MSG is much more prevalent than many people realize. Below is a list of some common food items that contain it from MSGTruth.org, but remember to look for the "hidden" MSG names (listed above) on all processed foods you buy.
* The Following McDonald's Items:
Grilled Chicken Filet
Hot and Spicy Chicken Patty
Grilled Chicken Ceasar Salad
Grilled Chicken California Cobb Salad
* Seasoned Beef
* Sausage Scrambled Egg Mix, Sausage, and Sausage Patty
* Doritos?
* Pringles? (the flavored varieties)
* KFC? fried chicken and most of their other products
* Boar's Head? cold cuts and most of their hotdogs
* Progresso? Soups
* Lipton? Noodles and Sauce
* Lipton? Instant soup mix
* Gravy Master?
* Cup-a-soup? or Cup-o-Noodles?
* Planters? salted nuts (most of them)
* Accent? (this "seasoning" is nearly pure MSG)
* Sausages (most supermarkets add MSG to theirs)
* Processed cheese spread
* Supermarket poultry or turkeys that are injected or "self-basting"
* Restaurant gravy from food service cans
* Flavored ramen noodles
* Boullion
* Instant soup mixes
* Many salad dressings
* Most salty, powdered dry food mixes
* Flavored potato chips
* Gelatin
* Canned tuna
* Hot dogs
* Soy sauce
* Worcestershire sauce
* Kombu extract
* Dry milk
* Dough conditioners
* Body builder drink powders containing protein
* Medications in gelcaps (contain free glutamic acid in the gelatin)
* Fresh produce that has been sprayed with Auxigro, a plant growth enhancer that contains hydrolyzed protein(s) and MSG (some of these crops may be used in baby foods)
Your best bet as a consumer looking to avoid MSG, for whatever your personal reasons may be, is to be diligent in reading processed food labels.
In general, the more highly processed a food is (or the more ingredients listed on its label), the more likely it is to contain MSG. Meanwhile, try to limit the number of processed foods you eat overall and you'll inevitably reduce your chances of eating MSG, too.
