I can't really grasp what this study is saying, Old Mike, other than there are differences, do you care to give a layman's version
I'm sure you can also answer some other things I wonder about
. Am I correct that there could be a correlation with vitamin D levels and UC? My vit D levels dropped substantially when I developed UC. I don't know if it was a cause or effect.
I also wondered what the worldwide prevalence of UC is. Is it a western disease that is becoming more prevalent in countries that are adopting a western diet?
