True that those don't have added iodine. I guess I didn't elaborate enough when I said it's added in the factories.

Although all salt has a trace amount of iodine naturally, it's not enough for RDA. So the labeled iodized salt has iodine added in the factory.

Also, I might add... Iodine is a poison, yes. The amount of table salt needed to consume would kill you long before any I'll effects of iodine were felt.

All salts have natural iodine, but not enough for the recommended daily allowance. The right amount is added in the factories.

For the most part, natural iodine is found in food, mainly seafoods, but it's also in plants that grow in places that weren't ablated by glaciers. These areas were known as the goiter belt.

And all the different salts, even the most expensive stuff, are functionally the same. One may taste better to you over the other due to taste bud differences formed by the foods you eat, or size of crystals, or other small things. But, in general, salt is salt.

More specifically, iodine deficiency causes goiters, neurocognitive impairments, and in severe deficiency, hypothyroidism resulting in cretinism.

Akron, Ohio was where a whole bunch of school girls were given iodized salt with their parents permission, with resounding results.
