I agree, how else to you explain the longevity it Asian cultures that have loads of salt fermented foods. Kimchi anyone?
I believe that some to many autoimmune diseases are sparked by various pathogens that try to disguise their dna by mimicking ours and eventually provoke an autoimmune response on the tissue it is hiding in and mimicking.
Absolutely correct, some of those same pathogens enter our bodies through the misguided use of vaccines. I know there is much disagreement, on this site, but vaccines have a dark side and may be the cause of modern day syndromes and immune distress which manifests itself in many seemingly uncontrollable forms.
