> In a recent podcast about fluoridation in tap water, they were talking about how they avoid iodized salt, because iodine is a reactive chemical and you don't want to OD on it.

That's a total fabrication. Here's what they actually said: https://www.youtube.com/watch?v=X_iJaExg2_4.

To summarize their point: the fluoridation of drinking water and toothpaste is unjustified, because what is used is not the fluoride salt that has been demonstrated to have benefits for stronger bones/teeth, and on top of that the distribution method is absurd because you can't control for how much water people drink. Then Bret brings up that iodized salt is a similar case in that the distribution method via table salt doesn't allow you to titrate, but that it has nevertheless been a success that solved major problems. That they personally don't use iodized salt because you only need to avoid a deficiency, which is also achieved via a balanced diet, is a separate point.
