I just learned about the awful effects of iodine deficiency and how incredibly widespread it once was the other day from a youtube suggestion[1] about iodized salt.

Previously I had thought iodization was mostly for preventing thyroid issues in the event of nuclear fallout, but no! It was a way bigger deal. For example, I had no idea it was the origin of the term "cretin"[2].

Sadly a lot of salt in the stores now boasts iodine-free.

I actually had to buy the cheapest 99 cent salt shaker to get one with iodine and I add a few sprinkles to most of my kids meals. Just to be safe.

TIL that "cretin" and "Cretan" aren't the same word. I guess I'm glad to know that the etymology is ableist instead of racist.
