The idea of fungus overgrowth has been on my mind lately. It was even suggested by my allergist. I had the candida test done with no results (also had a test for other allergens, including food, nothing showed up). However, she did say that the test results mean that nothing showed up in my "external blood" (aka the blood that was drawn), and that doesn't mean I couldn't have antibodies in other portion of my blood that happened to be circulating elsewhere in my body. I also remember my GI doc telling me that even if blood tests turn out to be negative, it's still not a 100% proof that nothing's wrong, and that the best thing to do is to find out through trial and error.
Anyway, as I wrote in my other recent post, I keep thinking about how well I felt on the SBD, and how much worse I feel when I eat lots of grains and sugar. I think I will give the diet that Kim often describes here a proper shot (talking about knowthecause.com). I already sort of eat that way (well, on a good day ) but I still eat grains and some sweets.
