Look it up. Iodine is an essential nutrient that our thyroid uses to regulate a whole host of things in the body. Eliminating it opens us up to a whole host of illnesses. There was a huge campaign in the 90s to get people to understand the value of iodine and it was put in all our salt so that people wouldn't have to think about taking it and would just get it whenever we salted our food. Iodine is so powerful it can cure people from radiation poisoning. It's anti-parasitic, anti-fungal, and anti-bacterial. It's like salting your food with chlorine dioxide or any of the other tons of antiseptic medicines they're trying to keep us from ingesting so they can sell us expensive drug treatments.
I was just at Costco and not a single kind of salt they have there says it's iodized. I thought maybe it was just the sea salt but I checked that huge bag of table salt they have and it doesn't say it's iodized either. I have that in my emergency storage and now I'm starting to think it's practically worthless. Sure, salt is good for you, but there's no question that iodized salt is WAY better for you.
Ditch your fucking sea salt. It says right on the label it doesn't contain iodide/iodine, "an essential nutrient." Get yourself regular old iodized table salt and thank me.
There isn't enough iodine to really help you in iodized salt. You have to get just iodine and there are co-factors you should take with it, vitamin C and selenium. Sea salt does have trace mineral we need so don't ditch it.
It’s worth researching the evaporation rate of iodine out of salt. Also worth researching how the salt is chemically bleached and stripped of the other trace elements that make it healing.
Iodine rich foods mostly come from the sea and from animal products such as meats and dairy.
I sudd suspect that it had meaningful levels in the 60’s, and that since then they’ve dialled back the amount of vitamin D in it and convinced people to drink less milk.
