I'm reluctant to try much of anything at this point, other than fruits, veggies, and meat. I had a mild flare eating walnuts a few weeks ago (I'll try them again sometime soon, just to see if I do any better). Also had a very mild flare with chia seeds (although I'm still up in arms over whether it was those and might have to try them again as a test). I had a bad flare a week ago on purpose though, just to test the validity of the diet (I ate a burger and fries from McDonalds). I had a bad flare and some intense stomach achesyesterday because I ate zucchini pizza (just mozzarella, ham, and pineapple on top of zucchini rounds dipped in pizza sauce). The mozzarella must have done it, which was very disappointing as I was just starting to think my diet would allow dairy. Is mozzarella bad? I've done okay with small amounts of cheddar and plain greek yogurt (I even ate some homemade cheesecake for my son's birthday that didn't upset my stomach or flare me up, didn't eat the crust though).
