One must understand that this cause and effect relationship is speculation…
After dinner last night I got wavy lines in my vision, my vision then went very blurry on one side, and later on me head felt filled with cotton balls with a slight pain down the other side. Like the symptoms of a migraine without the splitting headache. What had caused this…
Another person, with a working brain, drew me to the Black Bean sauce that I had used to make dinner. Consulting the labelling I found no mention of MSG, the only unknowns in the ingredients being food additives 627 & 631.
Searching Google I found Food Standards Australia New Zealand has lists of Food Additives, jumping straight to the list by number version we can see that they are: “Disodium 5’-guanylate (flavour enhancer)” (627) and “Disodium 5’-inosinate (flavour enhancer)” (631). So no Monosodium glutamate (MSG), its number is 621.
Another interesting result was the All additives page on the Food Intolerance Network site. It lists 627 and 631 as things to avoid. And says the following about these additives:
“The adverse effects of MSG (621) are well documented. We have also received many reports of skin rashes associated with new additive 635 which is a combination of 627 and 631. Yeast extract, hydrolysed vegetable protein (HVP) and hydrolysed plant protein (HPP) are ways that manufacturers include MSG without having to declare it on the label.“
So it looks to contain a MSG substitute.
Thought, the Australian Glutamate Information Service site, www.msg.org.au, explains there is no link between MSG and migraines.
“a 1990 critical review of the literature on food-triggered headaches (Food triggered migraine: a critical review. Annuls of Behavioural Medicine, 12:51-651, 1990) concluded that the relationship is controversial. The review states that there is no evidence to support an association between MSG and migraine headaches.“
So, I suppose there is nothing to it, and I’ll have to look for another cause.
But who is Australian Glutamate Information Service? It appears that AGIS is an industry body set up to “restore the reputation of monosodium glutamate (MSG)“.
