I would suggest getting very familiar with your specific areas of inflammation--prove it with various scopes/pill cams over the years. Then consider whether YOUR problem foods are associated directly with the segments of the digestive tract (from mouth on down) that are inflamed. If people would, ideally, match their disease profile with others of like inflammation locales, then you could compare notes to get a more telling list of foods to avoid.
Obviously if you have a more significant structural problem, like a stricture, then it is safe to assume anything bulky would cause problems from time to time. But minor patches of inflammation, which I have a handful of, could perhaps be associated with foods that are broken down in those areas.
Maybe that is too much of a generalization, or not. However, I personally associate my coffee(caffeine) intolerance with slight inflammation directly at the beginning of my small intestines. On that note, I have since reversed that specific intolerance with the supplement NAG (n-acetylglucosamine), just one pill a day. Whether this is helping any other problem areas, I have no idea. All I know is that is the only change I've made, and I can now drink coffee daily--for over a month now.
