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.

Plants get it from the soil, onto which the iodine gets deposited. There is no breathing apparatus involved.

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
