Allergic to sea salt??

[KnottedYet]

Thanks for the clarification. It's no wonder that I nearly flunked chemistry in high school! My container of California Sea Salt states, "This salt does not supply iodide, a necessary nutrient." I guess iodide and iodine are different, huh?

Naw, they're pretty much the same thing. But since sea salt from that patch of California salt flat may not have the minimal required amount needed for proper thyroid function, they have to label it as being deficient. Salt from another patch of salt flat or from one salt mine or another may have the minimal amount, or may have much more than the minimal amount.

Goiter hardly ever showed up in sea-shore cultures, so a lifetime of eating from the sea does supply enough iodine. But if all a person gets is sea salt (and not sea food) they may not get enough. Or, if they happen to be lucky enough to get sea salt with a lot of natural iodine they may get plenty.

I read a really interesting book about early 1900's inland China, and the rampant goiter in the population. Meanwhile, up in the Himalaya there was less goiter because of the access to salt from the Himalayan salt deposits (and fossilized sea creatures, way up high in the mountains! its a very cool area geologically.)
