Our bodies require very little Iodine, in fact about 1 teaspoon throughout our entire life is enough. That doesn’t mean you can take it in one hit because that figure is spread over your lifespan.
So how is it possible that intake was sufficient ten years ago but is insufficient today?
The major reason is that most nations have stopped using Iodine solution to sterilize milk containers before bottling; today they use a Chlorine solution. The old system used to leave a beneficial contamination of Iodine that mixed with the milk when it was bottled. This amount was sufficient to fulfill the needs of our bodies.
