> I think, outside Europe, this afflicted lots of places away from the coast, right? Like the middle part of the US. That's exactly where it afflicted people in europe as well, mountainous regions tend to be inlands, and from their remoteness don't have the opportunity for incidental iodine through trade, so they worsen the odds, but historically distance from the sea (and thus lack of sea products) has absolutely been the primary issue. CIDS was also endemic to the english midlands for instance. > I’ve always wondered if the iodine in the air is part of the allure of the seaside. No, intake from air is considered insignificant.

intake from air is considered insignificant But, intake from air is how the soil & plants get it, over long time scales… It’s always possible that a simple indirect selection is at play, e.g. people who simply love the sea breeze (for no particular reason) are more successful because they get enough iodine. Then, the next generation is more likely to love the sea breeze.

There is no breathing apparatus involved. > It’s always possible that a simple indirect selection is at play, e.g. people who simply love the sea breeze (for no particular reason) are more successful because they get enough iodine. What part of “intake from air is considered insignificant“ did you fail to understand? You don’t breathe in iodine, it’s been observed to not be a thing.

    1) your great grandparents loved the ocean air and thus moved near the coast 2) plants near the coast have iodine because iodine has been blowing in from the ocean and depositing on the soil for eons 3) you eat those plant 4) you don’t have an iodine deficiency because your ancestors moved to live by the sea
