This 'in full' paper on Fluoride Alert raises some interesting questions and information. I found it whilst trying to better understand the role of fluorine in hyperthyroidism.

Is fluoride-induced hyperthyroidism a cause of psychosis among East African immigrants to Scandinavia?

Viz local waters in some parts of Africa can contain 10 -40ppm of fluoride which raises the question what levels of fluorosis and thyroid problems do these groups have; one of the attached papers looks at fluorosis in Africa, which I will read and link here later.

This video clip http://www.youtube.com/watch?v=UkJuWLMaoG0 is intriguing (but has no details as to the speaker or occasion). If correct the information would seem to be of importance; viz that fluoride can substitute for iodine in T3 and T4, and tests for them will not differentiate between the iodine and fluorine content of T3 and T4, which would surely have a raft of implications. For example could a fluoride rich T4 result in higher activity in a still healthy thyroid because it fails to satisfy the body's demand for iodine?

It is also suggested soy is high in fluorine. I have seen this suggested before but not a paper as yet; if correct is high fluoride an inherent property of soy or a consequence of the type of the land it has been grown on?
