So you get to read the packaging every time you use table salt? When at a restaurant. Or using salt packets from a fast food joint. Or from plastic utensil kits.
Yes you know what’s in it in theory when you purchase the container at the grocery store. But anywhere you go it’s usually just a glass jar of salt. How are you going to know what is in there?
And finely ground salt does have additives based on the process to help it not cake up and flow properly which are stated on the packaging. When I read something as generic as “anti caking agents” I make no assumptions about what may be included in that statement.
