This is a particularity interesting 1955 ! paper where the authors have clearly grappled with the issue of the interaction of flouride and iodine, and as to whether adequate iodine will overcome excess fluoride, when considering thyroid function. They were clearly well ahead of their time.

They starkly conclude that iodine will not negate the inhibiting effects of high fluoride on thyroid function.

They also emphasise the importance of other inhibitors of iodine metabolism.

It is somewhat ironic that this observation was made over 50 years ago.

The Relationship Between Fluoride Exposure & Goitre in South Africa - March 1955

Abstract - several pages of excerpts from the paper are cited

"Prophylaxis and Treatment of Simple Goitre. – It is generally accepted that man’s physiological requirements of iodine is approximately 2.0 ug. per kilogram per day, i.e. if man daily ingests this amount of iodine there should be no significant enlargement of the thyroid gland. However, recent researches into the problem of thyroid enlargement have revealed to us various interesting and important factors upon which the normal function and size of this gland depend. These factors have been discussed under III and VIII B. It has become obvious that we cannot lay down a single definite figure for man’s daily iodine requirement as it depends upon various factors, e.g. goitrogenic foods, goitrogens in the drinking water, goitrogenic medicines, bacterial infections, and vitamin deficiencies. Fortunately, as a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man’s daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine, as happens in areas where the subterranean waters are heavily contaminated with this halogen. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water. Also from the point of view of general health this is the correct procedure…"
