Monosodium glutamate, or MSG, has long been at the center of
health debates. Government agencies claim that it safe while growing scientific
evidence says the opposite. MSG has been shown in several studies to have
neurotoxic effects, and although the government agencies claim that problems
associated with MSG affect only about 2 percent of the population, many health
experts say that number is significantly higher. Moreover, they aver that MSG
is at the root of many health problems for tens of millions of people.
But while other substances known to cause sensitivity or
unwanted health effects can be clearly identified -- and avoided -- simply by
reading food labels, MSG can be called by many different names and is used in
many different substances, making it extremely difficult to identify monosodium
glutamate and all its hidden forms by packaging alone.
You may know that another common term for MSG is processed
free glutamic acid, and that can help in weeding out some products; however,
because MSG is used in the production or processing of so many products, you
can still experience the consequences of MSG even when it's not specifically
listed on the label.
For instance, according to the site TruthinLabeling.org,
which is dedicated to monitoring MSG in food products, any of the following
labeling terms indicate that MSG is present (3):
- Glutamic acid
- Hydrolyzed protein of any type
- Monopotassium glutamate
- Protein
- Glutamate
- Whey protein concentrate
- Autolyzed yeast
- Citric acid
- Other ingredients that almost always include or produce free
glutamic acid during the processing phase include:
- Seasonings
- Bouillon, broth or stock
- Any "flavors" or "flavoring," including
so-called natural flavoring
- Anything "ultra-pasteurized"
- Pectin
- Amino acids
- Maltodextrin
- Carrageenan
- Oligodextrin
- Barley malt, malted barley or malt extract
- Brewer's yeast
- Citric acid, Citrate
And finally, the site lists the following ingredients as
being suspected of containing enough MSG to serve as triggers in those who are
highly sensitive to the substance:
- Modified food starch
- Corn starch
- Dextrose
- Rice syrup
- Corn syrup
- Brown rice syrup
- Annatto
- Products that are "pasteurized"
- Milk powder
- Lipolyzed butter fat
- Reduced fat milk
- Mmost products that are identified as "low fat" or
"no fat"
- Vinegar, including balsamic vinegar
- Products that list the terms enriched or vitamin enriched
What's worse, if you think you'll be "safe" by
purchasing food products from health food stores, you couldn't be more wrong.
Protein powders and essentially any food containing hydrolyzed proteins is
highly likely to contain MSG, and although products labeled "organic"
cannot contain MSG as an ingredient, other ingredients used in organic food
production may use or create MSG. For instance, MSG may occur naturally in some
products, including tomato products and cheeses -- especially parmesan cheese.
But simply because it occurs naturally doesn't mean that it's safe to consume
or won't cause reactions in people who are sensitive to it.
And food products aren't the only culprits. MSG can be
hidden in fillers used in dietary supplements and drugs -- even in personal
care items like shampoo, soap, body wash, conditioner and cosmetics, all
products that allow MSG to be absorbed by the body. MSG is also commonly used
in many pesticides, herbicides and even fertilizers, resulting in residues on
or within the edible portion of fruits and vegetables.
