Wow, thanks for all these interesting responses, everybody! That Himalyian Salt sounds pretty interesting too.
Today, I stopped off at my local food market and just got some regular iodized salt. Next time, I'm going to look for iodized sea salt.
ehbeth, I didn't realize soy could be a problem. I do have soy products once in a while, but I guess as long as I don't overdo it, it won't hurt.
I knew spinach was good for the thyroid, but I didn't know almonds and peanuts could be a problem. I guess it's like the soy -- ok, as long as you don't overdo it. The article you posted didn't mention cashews, so I assume their ok?
It's funny, sometimes you could be eating things you think are healthy without realizing you might be causing a problem!
