Thank you for taking the time to write such a long reply. That was very kind of you.
Regarding the book, it was by the author you mentioned. I had lent it to a friend who loved it and then lent it to another friend so I cannot access it right now. I just remembered the caution about monitoring the thyroid levels, but I am imperfect so I am not sure exactly what they said.
I don't mean to be rude, but I am still trying to understand all of this. Because the internet can be such a strange place to get information, I want to make sure of some of the things you said.
1) Do you recall where the reference article(s) is (are) that gives the information about the "transient" increase/decrease in the level of the thyroid hormones? I can understand if you don't have it right off hand, though. I'm just curious, although it makes sense that the human body would adapt.
2) For the autoimmune thyroid disease and the thyroid cancer, you mentioned that 'if Iodine were the problem, there would be less of these diseases now since Iodine is less available, but there are more problems now.' However, I think that you are referring to a deficiency problem: It is well known that a deficiency causes problems and is already documented, but my question was regarding a surplus. For example, a deficiency in iron can cause fatigue (from anemia), but a surplus can also cause fatigue (hemochromatosis).
Almost every vitamin and mineral causes problems with too little AND problems with too much. Even water. I was wondering at what "point" would the surplus in Iodine start causing problems. If there is a dosage or a period of time of the dosage that makes the difference? I suppose this may not be studied fully.
Thanks for all your help. I do not expect for anyone to answer all the questions. It is something that I have just been thinking about.
