MSG and emotional volatility

10 Oct

For some time I have suspected that the emotions of our daughter may be influenced by MSG.

She really likes ramen noodles.  The taste of them, rather.  Those little flavor packets containing MSG high up on the ingredient list.

Myself, I get migraines if too much MSG is ingested.  Since I cook most of our food from scratch, that leaves only snack-type stuff.  Which we do not routinely have in the home.

The girl didn’t think MSG had any impact.  So Saturday lunch we ran a little test.  She had ramen.  I added a half cup of homemade salsa, and a bit of onion and carrot.  She complained that they did not taste like they should.  It seems she uses half the water the recipe calls for.  Hmm.

In nine hours time she was saying things she should not have.  Then bedtime.

The next morning (Sunday) the extreme emotional volatility continued until about 6.00 PM.  It was a day of hell.

My few minutes of research on Pubmed this morning indicates 1)L-glutamate is the primary excitatory neurotransmitter in the mammalian central nervous system (CNS).  This paper indicates that if the glutamate removal system is impaired, your retina (ergo your eyesight) will suffer.  Not to mention the neurotransmitter will just keep those neurons firing.

2) MSG is used to induce metabolic syndrome (obesity and its attendant characteristics) in lab animals.

3) Exposure to glutamate in young lab animals can induce seizures (think epilepsy).  Makes sense: an exitatory neurotransmittor set loose in a young, still  forming brain…

4)MSG is used as the agonist (stimulator) of choice where measurements of specific brain activity in research mice where measurements are needed.

 

Today, it must be noted, she was sweet as pie.  And she seems more amenable, at this time, about watching the contents of what she eats.

    It is scary what goes into packaged foods. Maybe this was a learning moment for her to use later in life? Glad to hear she is back to normal!
