Hi yes I have trouble with some fruit and some vegetables and there does seem to be considerable overlap with some of the categories within FODMAPS. (My primary care doctor talked to me about FODMAPS and there's quite a helpful presentation at http://nutrition.otago.ac.nz/__data/assets/file/0017/5714/FODMAPs_13.5.10.pdf
I'm fine with most of the low fodmap fruit and veges, including kiwifruit, grapes, mandarines, oranges, bananas, rock melons, carrots, green beans, pumpkin, zucchini, tomato in moderation (a bit acidic maybe), but can't eat much lettuce for some reason. I can also eat potatoes, but currently avoiding to reduce starch for the AS.
Fructose definitely seems to be a problem for me. Apples have been guaranteed to give me stomach pain/gas/reflux etc for years and I'm not great with pears either. I dislike the taste of honey (maybe my body telling me something), can't handle fruit juices, but I do drink the occasional glass of wine.
Fructans are interesting. I can't tolerate anything in the onion line, and don't normally have asparagus. Until recently I have loved my bread, but now avoid wheat and rye because it seems likely implicated in my AS, IBS and insulin resistance.
Cabbage and brussel sprouts, which are galactans, are no good at all for me, but I do eat some broccoli (feel like I have to have something green)and tofu. And I can also eat the stone fruit, avocado and mushrooms that are in the polyols list, but not cauliflower. It might be something else about cabbage and cauliflower that is a problem for me.
I haven't noticed any problems with dairy, but I know that others do. I have a cup of yoghurt with fruit for breakfast every day.
So far I've been just using the trial and error approach although the ones that are no good at all have made it very clear to me! We're all different so in the end the answer will be different for each of us.
Sorry if this was a bit long and self-centred, but I have been thinking about this lately and it was helpful for me to go through the exercise.
