Iodine deficiency ! - falling intakes - goitregens - competition bromine and fluorine

[R.B.]

Another accidental find, not what I was searching for but is fascinating.

If you open this link http://books.google.com/books?id=7v7...ontent&f=false
it will take you to a page of a book called the Iodine Hand Book.

The graph graphically shows the effect of food based iodine blockers on the uptake of iodine by the thyroid; the effect is significant !

Earlier graphs in the pages above the one referred to show that the body maintains fairly stable levels of T4 in-spite of the presence of food based iodine blockers where iodine is adequate.

Another graph shows the effect of iodine intake an blockers on thyroid size.

The relative distribution of iodine between organs and tissue in the body is presumably dependent on iodine intake. I postulate if intake is low most iodine will be found in the thyroid, but when iodine intake is high most will be found mainly other tissues. This would explain the different figures that are given as to the distribution of iodine in the body. The gender of the test animal will also logically have a bearing on the results.

It appears the body is protective of the iodine status of the thyroid, and the focus on it to the exclusion of other iodine research is distorting our views and knowledge on wider iodine metabolism.

The atomic and molecular properties of iodine, its size, potential to bond in many different ways, and odd snippets of research suggest we have hardly even begun to understand the wide roles of iodine in the body.
