I found this tonight in an old file I hadn't looked at in sometime.
It is a good reference as to the various causes of seizures.
This has to do allot with Neurotoxins, aka: 'Excitotoxins', that denatured Glutamate, and Aspartates are the key sources of along with sugars, both artificial and natural."ingestion of those "species-inappropriate" foods, gluten (wheat, notoriously, and some other grains), casein (in cow's milk - not in goat's milk; it isn't the lactose, which goat's milk has lots of too), soy, and (to a slightly lesser extent) corn that can often cause brain seizures (in humans or animals)."
Soybeans also go through a process that most often includes using Hexane and organic compound, that is a toxin. Sometimes it is in the processing that foods become potentially toxic, not the compounds in the natural foods alone. For in concentrating any source, including natural sugars, lecithin, whey protein, this can occur.
