Mat, first off, here's the link to the article about quercetin with lots of links to studies. Quercetin is in apples and lots of other things, but in very low concentrations. You'd have to eat a lot of apples to get there. I take 500 mg each morning with breakfast, and have been for a week or two now. I can't tell if it's helping now, but it seems like it is.

The paleo diet, or a more ketogenic form, has been very helpful to me, but sometimes, perhaps often, there are exceptions, and one has to find what works best. There are some general rules that seem to apply to pretty much everyone, like sugar is bad, gluten is harmful, and so on and so forth. But the Mediterranean diet is pretty healthy, I think, as long it it's not too heavy on the starches, which it can be at times. But fish, olive oil, lots of vegetables, and perhaps even some legumes (not permitted really on the paleo diet) can all be very healthy. In my case, carbs and sugars, even fructose, are problematic, but I know that mine situation is gut mediated, so I'm not surprised.

Again, sorry to hear about your woes with the medical profession. I'm involved in my own struggle, but I have some good physicians here, so hopefully I'll get some answers. I'm young now, so I just worry about further degeneration as I age. One reason it's so difficult is that one doesn't know what to expect with this, especially since I don't know what is causing it. If it is my gut, and I can fix that, which I'm trying to do now, then I may be able to fix what has happened and if I'm at the autoimmune phase/it has already been triggered, then perhaps I have put it into remission, whatever particular disorder it is.

Good luck!
