I mean I'm eliminating all classic food offenders, NO gluten dairy grains nuts etc... even cut out all vegetables since I've had them the whole time and they might be the cause (who knows) so basically just proteins and sweet potatoes/avocados/coco products/lettuce and dark chocolate - and I'm STILL feeling worse every day. How long after trying the diet would you feel changes ?
Twice I saw you list sweet potatoes and then once you said no alcohol. I assume you meant "booze". But I want to share my experience as I can't drink it nor eat it - ie sweet potatoes have enough mannitol to trigger me. Same with things like cherries - especially cherry juice which has sorbitol. So I wasn't sure if you meant grain booze or sugar alcohols - both are bad triggers for me.
I also found all lettuce of all types was immediate trip to the bathroom. (I do miss salad but now I Make it without the lettuce). It's easy to dismiss a whole food group but dangerous so I try to avoid doing that myself. Cherries may not be okay but I can eat all the wild blueberries I want - even blueberry juice is okay, but after a few days and few handfuls of fresh cherries or a bit of the juice and I can feel my body start locking up, heart going crazy etc. Took me quite some time and detective work to figure out what works and what didn't (Years) and sadly it changes at times. The food journal really was the only way for me as we are so different. And it took a long time because once you have reacted, you almost have to wait until it passes to try new food items. It seemed I got on a ten day cycle. if I had a bad reaction - it was ten days before it was gone and I could try a new food. I fasted for days and then started off with potatoes because I was intolerant of everything else at the time, even rice.
For me everything you listed is a trigger - I don't digest the fats in avocados well, though I have grown increasingly tolerant of them and keep trying them for the fat component. LOVE chocolate but it never loves me back. I don't eat meat personally but I have also read that protein in the form of meat from grain fed animals can trigger people - so maybe consider protein from non grain fed animals if you haven't considered this already.
I still go through periods where it seems the only thing I can eat is non-gmo organic potatoes. I roast them and pile them high with fresh herbs like rosemary and tyme and sea salt. The one nice thing is my grocery now carries three kinds of these potatoes - red, white and yellow! I take what variety I can get these days.
I sense the frustration and sadly can relate all too well - people kind of laughed when I would say no food seems to agree with me. But that is really TOUGH spot?? We need to eat? It truly is not a laughing matter - I hope you find something that works for you soon. If it helps at all - I can now eat all kinds of foods (again within reason - no gluten dairy sugar alcohol etc) BUT yesterday I made gluten free apple fritters and I still feel okay from them!! There is hope - it just takes time.
