The glutamate industry and
companies, including pharmaceutical firms, that wish to use processed
free glutamic acid (MSG) in their products, improperly claim that the
term "MSG" only applies to the food ingredient "monosodium
They pretend not to realize
that "monosodium glutamate" is nothing more than glutamic acid
that has been freed from protein through a manufacturing process (processed
free glutamic acid), salt (sodium), and moisture. It is the processed
free glutamic acid that MSG-sensitive people react to, providing that
they ingest amounts that exceed their tolerances for the substance.
Consumers may react to processed
free glutamic acid that is contained in any food ingredient or product,
including AuxiGro, regardless of the name of the ingredient or product.
Because MSG-sensitive people
may react to all ingredients and products that contain processed free
glutamic acid, they refer to such ingredients and products as containing
In August, 1995, the Food and
Drug Administration (FDA) noted in a document entitled the "FDA Backgrounder"
that consumers frequently refer to all [free] glutamic acid as "MSG."
The "FDA Backgrounder" is still in use by the FDA and can likely
be found on their Web site.
Based on peer reviewed studies,
there is no question that glutamic acid is neurotoxic. This can be easily
confirmed by accessing MEDLINE retrieval service for studies dating from 1966 to the present, using the
words "glutamic acid" in combination with the words "brain
lesions" and then "neurotoxicity." I would also suggest
that you look up the words besity," " and "seizures"
combination with the words "glutamic acid."
There is also no question that
the young are most at risk from MSG. To confirm this, you might start
by reviewing the work of John W. Olney, MD and look up the words "glutamic
acid" in combination with the words "blood brain barrier"
and "placental barrier."
You will learn that the blood
brain barrier is not fully developed in the young to protect against toxins
that enter the blood, and that glutamic acid can also penetrate the placental
Disregarding the blood brain
barrier and the placental barrier issues, the literature clearly indicates
that, based on the amount of MSG used in the 1970s, over
25% of the population react to MSG.
Although we have not reviewed
all vaccines used on infants, we have found one or two sources of processed
free glutamic acid (MSG) in those that we have information on. In discussion
with a retired executive of a company that produces vaccines, he suggested
to me that all viral vaccines would have free glutamic acid, used to feed
the live virus.
The glutamic acid in vaccines
are often described as "stabilizers," i.e., ingredients to keep
the virus alive. We describe them as a hidden source of processed free
glutamic acid (MSG).
An example for you would be
the Chickenpox Vaccine by VariVax -- Merck & Co., Inc. (Merck). This
vaccine includes "L-monosodium glutamate" and "hydrolyzed
Another example would be Merck's
M-M-R vaccine. The product insert states that the growth medium for measles
and mumps includes "amino acids" and "glutamate."
It is also stated that the medium for rubella included "amino acids"
and "hydrolyzed gelatin." Finally, it states that the "reconstituted
vaccine" for subcutaneous administration includes hydrolyzed gelatin.
We have no way of knowing which
amino acids are used in Merck's vaccines, but we do know that the amino
acids "glutamic acid," "aspartic acid," and "L-cysteine"
We also know that any hydrolyzed
protein, such as the hydrolyzed gelatin will contain some processed free
glutamic acid (MSG), some aspartic acid, and some L-cysteine, all considered
to be neurotoxic by neuroscientists. Even without hydrolyzing gelatin,
gelatin contains over 11% processed free glutamic acid (MSG) and some
aspartic acid and L-cysteine. It is present as a result of the manufacturing
process that results in gelatin.
The product insert for M-M-R
vaccine by Merck provides a contraindication that states, in part: "Hypersensitivity
to any component of the vaccine, including gelatin." It is footnoted
to the following reference.
I cannot help but wonder if
at least some of the subjects in the study above reacted to gelatin. Most
reactions to processed free glutamic acid (MSG), as contained in gelatin,
are not IgE mediated. They are best described as a sensitivity to a toxic
If you wish to determine more
about Merck vaccines, I would suggest you call their National Service
Center at (800) NSC-MERCK. Do not ask about the presence of "MSG"
in vaccines. Rather, ask about the presence of "free glutamic acid."
You will have a better chance of getting a reliable answer.
Not long ago, a vaccine for
Rotavirus came to market. The product, which contained some processed
free glutamic acid (MSG), carried a warning in the product insert that
it not be used for individuals who had a hypersensitivity to MSG. Shortly
after the Rotavirus came to market, it was found that the vaccine resulted
in digestive blockages, and the product was withdrawn from the market.
One last comment regarding
the exposure of infants to processed free glutamic acid (MSG): the presence
of processed free glutamic acid (MSG) in infant formulas.
We have found that major brands
of infant formula, if not all
infant formulas, contain some processed free glutamic acid
(MSG). The hypoallergenic soy formulas contain
very high levels of MSG. See www.truthinlabeling.org/formulacopy.html for further detail.
It might be worthwhile for
someone to do a study of people who were raised on hypoallergenic formulas
to determine if they have experienced a higher incidence of obesity, learning
disabilities, and/or ADHD, in childhood and/or endocrine disorders later
in life, as compared with people who were breast fed, and then as compared
with people who were raised on milk based infant formulas.
If I can be of any further
help to anyone on this important subject, they should not hesitate to
write or call. If anyone receives a list of ingredients from vaccine producers,
I would be pleased to go over the ingredients and advise them of the ingredients
that contain processed free glutamic acid (MSG).
