Ok , we know that Neolitical food , can cause to us a leaky gut , opening in this way the door to the worst diseases ever.
But , I take fro example Crohn Disease . In this site the gratest part of the people think that Crohn is caused by SIBO , but every person can have a SIBO , regardless of where they live , and so , why in Italy , Crohns is much more usual in Sicily , than in other regions?
Why , MultipleSclerosis is a lot more usual in the land of the north( sweden , norway ) and in Canada?
I can't explain this to myself...can you?
