Hey Brazilian Guy,
Regarding the spinach it has a significant amount of oxalates and biologically active amines. These require a fairly stable a strong digestive system to process and neutralize. Thus, lots of the information on the internet recommends removing it from the diet.
Have tried sauerkraut before. Didn’t seem to show any direct results. The cabbage juice can sometimes almost give me a head-rush (particularly if the cabbage is extra pungent). The only issue that I have seen regarding sauerkraut it contains a significant amount of histamine (especially well aged) and this may also put stress on the digestive process. But in the end, there is so much overlapping research that can become quite confusing. Best thing seems to be to test it out and see how it effects you.
Yeah, all of these things can definitely have an impact as these things effect overall immunity. If your system is weak, the bacteria causing the SD basically get proliferate with less resistance.
From what you indicated, it seems that you may simply have some type of systemic infection. In this case, the best course of action would be to see a gastroenterologist and have your insides inspected. This way you may pin-point the exact reason for your issues. Systemic infection -> weak immune system -> skin issues. Aids is just another thing that will cause intense immuno-suppression and thus SD results.
In terms of the magnesium deficiency, this can either be the cause of the other issues or a result of them. Will all the test you have had done, I’m sure that you’ll definitely uncover your issue. Luckily you have found a good doctor.
As for the pau d’arco tea, it didn’t seem to do anything for me. Let me know how it goes.
In terms of the research stuff, I’ll upload it some time this week and send you a link.
The questionnaire is also a really good idea and have actually thought of this before. However, I was initially unsure with how much people will participate. However, now that the site has been growing it is time to go back to this idea.
Hope that helps and let me know if I missed anything. In summary, keep working with the doctor, if he can pinpoint the main issue I really think your SD will disappear.
