I tolerate avocados, but don’t eat them. I tolerate some well-cooked plants, so things like broccoli, cauliflower, and Brussels sprouts, I can eat if we bake/broil them. I can eat things like bell peppers, if really well cooked. Many fermented foods, like pickles. No issues with olives. Don’t seem to have issues with nuts, unless they are high fiber, then I get gas and the like.
I can eat chocolate.
Things like cabbage are weird. Usually I require this to be well cooked. But sometimes I can eat it raw (as in coleslaw); other times, I can’t. Sometimes I can eat sauerkraut or kimchi, and sometimes I can’t.
I can eat a salad, just not that much. Once a week.
Salads were how I figured this out. I would eat low vegetables, but then go on vacation, and begin substituting salads for fries or whatever, and a lot of my issues like IBS, constipation, etc., would come back.
Also, I was trying a targeted keto diet (TKD), where I ate carbs after a workout. I found about the only thing I could eat was rice noodles. The sweet potatoes, japanese sweet potatoes, spaghetti squash, etc., they didn’t work.
Potatoes aren’t bad, though I very rarely eat them.
And these are hard to tell, because I think it depends on how you eat it. Eat something last is probably different than eating something by itself. Though I’ve not tested this. But I have a hard time figuring out why I can eat something one day, and have an issue another day.
But I often have days where I eat low to no vegetables.
