Sorry, I just realized I didn't list my issues:
-- celiac disease (gluten-free oats act similarly in my system as gluten)
-- casein intolerance
-- problems with some FODMAPS (especially high fructose foods and mushrooms)
-- problems with brown rice, as well as most gluten-free flours (such as coconut flour)
Things that I tolerate:
-- soy
-- white rice (and white rice flour) and cornmeal
-- tapioca flour
-- potatoes
-- most nuts, if soaked
-- cooked leafy green vegetables
-- small amounts of tomato sauce, eggplant, tomatoes, garlic, and onion
-- meat (though not too much animal fat)
-- olive oil
Things I am not yet sure about:
-- beans
-- fennel, zucchini, etc. (other low-fructose vegetables)
-- squash
-- eggs (seems OK if it's just every so often)
If I eat casein, my GI tract becomes inflamed for about two months and I tolerate a lot less. If I keep all traces of dairy, even ghee, out of my diet, then I can tolerate more foods over time. Gluten seems to affect things for several weeks, too, although I haven't completely identified the pattern yet (and hopefully never will, though I get an opportunity every time I accidentally eat some). If I keep gluten, oats, and dairy out of my diet, then I seem to gain more ability to eat other foods, such as fructose-rich foods, over time.
Soy gives me a gigantic mood lift -- without it I actually become depressed. I seem to be very dependent on food opiods to maintain a good mood, since gluten and casein also lift my mood to different degrees. I think I'm a bit weird in extreme responsiveness my body has to these opioids, but there is a lot of research to suggest that they affect most people to some extent.
