I am currently on a very strict low iodine diet for health reasons. This is not the first time I've been on the diet and in the past I've resolutely avoided all prepared foods and restaurant meals because I've never been able to verify whether a vendor or restaurant used iodized salt. As a chowhound, though, this is painful and I'm starting to wonder if I can loosen up on my restrictions.
Does anyone know how commonly iodized salt is used in restaurants? I know a lot of restaurants use sea salt, which I don't believe contains iodine, but, again, how common is this? I've been to restaurants while on the low iodine diet and asked whether the chef used low iodine salt and have received many confused looks (one helpful waiter actually tried to fish out an empty salt bag from the trash but couldn't find it).
I would greatly appreciate any comments, especially from those in the food and restaurant industry. This is a real quality of life issue for me.
