Damo, this is an interesting topic and I'm trying to sort out what others are saying and what foods/gas/flares all have in common.
From my few months of experience with UC, I'm learning daily that when I am NOT in remission (which for me means there is no bleeding, no urgency and 2-4 bms/day), I can have the gas which leads to soreness and then trying to "go" with no luck and eventually leads to bleeding. However, since getting on the prednisone, I do believe there has been a reduction in the inflammation of my colon. For the past week, I have been eating lots more veggies, which I typically strayed from b/c I thought I couldn't tolerate them. Now when I eat foods that before caused that "fart-flare cycle" I just get gas and some bloating along with some diahrea, but not like UC diahrea (ha!).
My question to you is---where do you think you are at --flare or remission? If you are still in the flare zone, maybe the foods you are eating are not being well tolerated by your gut b/c the inflammation is still there more than it should or could be. I hope this all makes sense. :)
