Most of this is beyond the level I&#x27;m at with biology, but I wanted to acknowledge your point about &quot;salt&quot;.  Just checked a carton of my normal, Wal-Mart Great Value non-iodized salt, and in indeed includes calcium silicate Ca2-SiO4, which is an anti-caking agent that&#x27;s thought to be generally safe, and looking at it I suspect that&#x27;s true.  But certainly not for everyone.<p>On the other hand, my &quot;salt is salt&quot; comment was more about how NaCl is NaCl, wherever it comes from, table salt, McDonalds, etc., and will have the same effects regardless the source.  Additives might indeed cause harm, but that won&#x27;t be directly linked to NaCl once it all hits the mixmaster of your stomach.<p>A bit more to follow in email.
