Theory One: Acid

Theory Two: Copper Deficiency & Sulfur

Instead, I'm having my dental amalgams removed, because the mercury contained therein is supposed to foul up minerals, hormones, adrenals, etc. So considering my huge number of fillings (17) this may be the true root of my problems, as many others have found out. Well... it remains to be seen, and I sure am nervous! Anyway, by the time anyone reads this, my dental revision may have been long past - in which case this paragraph will require an update! J OK, now, here's that excerpt:

Of course, in those rare cases when copper is actually deficient, sulfur-containing supplements, just like larger amounts of Vitamin C, should not be used, as they could trigger, or worsen existing inflammatory conditions. In addition, individuals with a tendency for blood sugar disorders (i.e. diabetes) should be aware of possible negative consequences on insulin production when supplementing glucosamine sulfate, which is usually used for arthritis. Possible adverse effects of consuming sulfur foods or sulfur-containing supplements (glucosamine sulfate, MSM, methionine, taurine, cysteine / cystine) include bloating or flatulence at higher amounts, while a very small number of patients have complained of a "stomach burning" sensation.

Theory Three: The Onion-Sulfur Theory

I know of a woman who underwent NAET allergy treatments. And she was getting better. But then, upon clearing for egg allergy, she began feeling worse and worse. Then it dawned on her that maybe because she had now started eating eggs, the sulfur thiols within them were binding to her body's mercury and redistributing it, thus causing pain. (This is available for reference on the Maelstrom NAET mailing list archives.)

In a similar vein, maybe people develop calcium intolerance for a similar reason? Perhaps it's because their bones leech calcium into the bloodstream in order to alkalize it to compensate for their depletion of magnesium & potassium? See:

Theory Four: The Astringent/Constricting Poor-Circulation Theory

So: Maybe onions/garlic (and family) contain a substance which contracts blood vessels (thus closing off my throat and causing headachiness?

By the way, I've recently been chewing on fresh dandelion stems and leaves, since it's said that dandelion is good for the liver. Well, guess what? Though not quite as bad as onions/garlic which cause sore throat, sinus drip and headache, the dandelion caused my throat to constrict very much, sort of like trying to swallow sandpaper. So I speculate that dandelion may share a substance in common with onions/garlic.

If anyone shares these experiences, it's possible that you may have very poor blood circulation, therefore astringent/constricting foods act as the last straw on the camel's back. Perhaps the antidote is arginine, which opens blood vessels? By this I mean arginine supplements, rather than foods which have both arginine and astringents/constrictives. I welcome feedback on this issue, because I know that arginine aggravates herpes, so therefore what do people do if they have parasites and viruses, at the same time as poor circulation?

Theory Five: Liver Related?
