Now, to be fair, I was once 20 years old and didn't want to answer questions like that, either! I wanted to be able to continue to eat the way I was eating. But with the family history you mentioned in your past posts, for example, the eczema, the thyroid problems, diabetes...those are all indicative of a bad diet.
We MUST clean up our diets! Bad diet, plus too LITTLE iodine, well, will not prove to be too successful in the long run.
I'm just being real, because I have learned (and am STILL learning) this valuable lesson for myself, and I am 53!
