theres multiple posts on the reddit sub about experiencing problems by removing iodized salt from diet.
i used to use pickling salt, it’s idiotic to cook and season with except in soups where it totally dissolves. i actually got some sort of stomach issue that lasted weeks before it resolved from accidently swallowing a bunch of undissolved kosher salt crystas in my coffee. i actually almost threw up a couple times drinking the super concentrated undissolved pickling salt crystals in my milk too
i went back to iodized salt
search the reddit sub. theres one user that says they/them are allergic to seafood and that xer got suicidal after two months off iodized salt and it instantly resolved in two minutes after taking a bit of iodized salt in the middle of the night when xer was on auto pilot as if their body knew they needed it
