I have had UC for around 2.5 years. Had one bad flare up and approx 60cm of my bowel is affected. 2mg of Pentasa keeps it under control and I can eat anything but alcohol is not good for it.
My UC was starting to turn bad and then I tried unpasteurised Sauerkraut, I ate approx half a dinner plate in the evening. The result was the next day my bowel was completely normal and has remained so. No pain, no diarrhoea, no wind. I’m not suggesting this is a miracle cure but it may help some people so I thought I would share it. I eat half a plate every day.
