How common is the use of iodized salt in the USA?

[RICHARD]

Does anyone of you know if hotels or restaurants use iodized salt? How common is the use of iodized salt anyway? Is iodized salt or iodine added to the food that you can buy in supermarkets? Do the labels declare that there's iodine in it?

Would be great if you could help by giving me some information on this subject!

Thanks,
Kirsten

Most of the salt is iodized here in the U.S. I don't know about the salt that is added to food, but I use kosher salt most of the time and can tell the difference between the different types. The IS has a metallic aftertaste and the KS does not.

HOpe it helps.
