was checking out more FODMAP info and came across this from FODMAP Life for those interested...

Foods & Drinks to Avoid for Ulcerative Colitis
Alcohol – Drinking alcohol can out you at risk for flaring or a relapse in the form of a severe and acute attack. Some health professionals suggest limiting alcohol intake during social situations and completely avoiding it at home.
Caffeine in coffee, tea, soft drinks, and energy drinks can stimulate the colon to contract which promotes more bowel movements. Also be aware of energy drinks made with the stimulant guarana.
Carbonated drinks – caffeine, sugar and artificial sweeteners can increase gas and the carbonation can cause cramping –ouch. I wish everyone would just give up soda – it’s the worst drink on the planet!
Milk or milks products – not everyone with UC has trouble, but take note in your diary if you experience symptoms. If you do have trouble it could be because you cannot properly digest lactose, the sugar present in milk and other milk products. Make an appointment to get a lactose tolerance test.
Onions are difficult to digest as they contain a natural type of sugar called fructose that causes gas – yet they can be found in so many foods! Read menus and labels carefully so you can avoid this stinky culprit!
Beans & Legumes – try smaller portions. Another example – instead of eating whole chickpeas, try a little hummus.
Raw fruits and vegetables might bother you, so try steaming, baking or stewing them.
Cruciferous vegetables can cause gas, bloating and cramping for most with UC (cauliflower, cabbage, garden cress, bok choy, broccoli, brussels sprouts).
Whole seeds and tiny seeds (found in strawberries and raspberries) can cause problems. Ground flaxseed and tamari (sesame seed paste) might be a better option.
Dried fruits have moderate amounts of sulfate (and are dense in sugar). The more sulfate you ingest, the more of it’s available for colon bacteria to make sulfide gases.
Corn and mushrooms (as well as broccoli and cabbage) are often times avoided during a flare up as they cannot be completed digested and can cause irritation in the gut as well as diarrhea.
Fatty meats – stick to leaner meats or ground up meat and remember to chew everything slowly and thoroughly. Tough meats like steaks can be very hard on the GI tract.
Whole nuts or crunchy nut butters as well as popcorn can cause irritation (and literally get caught) during digestion and bowel movements. Stick to smooth nut butters.
Rich foods (condiments, sauces) like carbonara sauce, Alfredo sauce, gravies, heavy desserts or mayonnaise can trigger symptoms.
Chocolate has both caffeine and sugar which can irritate the gut. Try consuming one small square of dark chocolate (has less sugar) to keep your insides relaxed.
Sugar alcohols found in sugar-free sweets and candies (like sorbitol or anything ending in ‘ol’) can cause gas, diarrhea, cramping -you name it!

Problem foods/drinks seem to be very individual-oriented as we've heard from people on this forum.
However…the lists you quote are pretty accurate for my gut with a few exceptions (my gut hates gluten breads and almost all grains for example).

Curcumin/turmeric note: the research showed that C3 form of Curcumin at 3000 mg/day keeps people taking conventional UC meds in remission. Not all curcumin is the same and needs higher doses than you can get sprinkling it on food.

Alcohol note: A couple of ounces of white wine act like Immodium on my gut, a positive benefit and nothing bad happens the next morning when I've had 2 glasses of it. Red wine however is a killer for me.
Never drink much vodka but it seems OK too, mixers are my problem with it (gut hates them).

I don't think a lactose test is necessary and could give a false negative in terms of being good idea to remove it. If your gut hates lactose you'll know. My lactose test was negative but my gut could not handle milk products while flaring so it went out of food list. Now that I'm non-flaring many milk products are OK.

I have not found a list of foods my gut agrees with but spent many years trying all the diet modifications there are. Ask your gut what makes it unhappy and then obey.

i'd agree with that listing except whole grains and cereal which are a killer for me. BTW, pb4 do you think that IBS may cause blood as well? how do you know that you have both ibd and ibs, it has always amazed me because the symptoms are so similar

thanks pb4, amazing how high-tech all these tests are on other continents. Seems like Poland is still deep in the medieval centuries, there's only one equipment for calprotectin tests in Poland, it's in Warsaw, but it is either broken or the staff don't know how to operate it. BTW, i think your symptoms now indicate remission, C is much easier to handle than D and ibs is really not big deal compared to uc. Congrats on your quick recovery path :)

I greatly agree that IBS is not much easier than UC but at least there's no blood haha. Not even sure I think my IBS symptoms are much different than UC symptoms were. I'm still doing diet mod. for symptoms, just don't need enemas. And cancer is not a concern for IBS (so far).

In my mind IBS is a nasty cousin of UC albeit with no physical changes visible. I never had any form of IBS before getting UC so not a progressive condition in my case, just an add-on. Stress is not a factor for me but can understand how that would aggravate symptoms.
