My understanding is the main thing deficient in our soil human healthwise is iodine, hence our salt being iodised. Various places around the world suffer from that, it hardly makes our soil "crap".
I thought our iodine in salt was a throwover from Coro Street England, with their crappy teeth and bbc men coming to take the telly for not paying the bill.
Nah, genuine lack in our soil. It happens in places.
So much so, that there is some concern that we'll need to change our iodine source as people either reduce salt intake altogether or use alternatives like sea salt etc, which isn't iodised.
