I'm rather surprised that you don't think that the gut is important in regulating the immune system, Prof Edwards, but at least you can't be accused of bandwagon-jumping, as there is a very big bandwagon at present about the gut microbiome and immunity!

It is certainly in keeping with my own experience of many symptoms improving after I brought about an improvement in gut function.
