I didn’t read other comments; this is my own .02:
Anyone curious about dietary issues should undergo a ritual cleansing (eliminating any and all processed foods from the diet) for up to 2 weeks and gradually add foods back into the diet. This is how I discovered I have some unknown sensitivity to processed garbage, but it has NOTHING to do with Gluten. I cook 99% of my meals with non-processed components (no white processed flours, nothing boxed with a long list of ingredients) and I’m fine until I eat out at a restaurant. Go figure.
Stories like this are interesting, but always make me suspicious when they point to a cure-all. Sounds a bit like snake-oil. Ya know?
I was able to figure out what the things that were affecting me by keeping a food diary. My allergist told me to write down everything I ate and then when I had a problem whether it was 30 minutes later or 3 days, I could see what the problem was by comparing what I had eaten before. It worked like a charm.
