Welcome to the forum.
Yes, PALEO works!
IMO it's because it's an anti-inflammtory diet.
If you are interested in other things that are natural too, there are things IMO that you can control, which will have a direct impact on
your disease, the symptoms you experience and their severity.
I was able to control my UC into remission through various
supplements, probiotics, diet modification, and LDN , low dose
For more info on the protocol which has put me into remission,
