Much of the following information, studies, links and inspiration is based on Jerzy Zięba's 2015 book "Ukryte Terapie" ("Hidden Cures"). Highly recommended!
Basically, Wolff and Chaikoff (Wolff J, Chaikoff IL "Plasma inorganic iodide as a homeostatic regulator of thyroid function", J.Biol Chem, 1948) destroyed the previously widespread and largely successful thyroid disease therapies based on iodine supplementation (*) by claiming that the excess iodine blocks thyroid hormone production. However, what their study did actually measure was the effect of stopped absorption of radioactive iodine in to iodine-saturated rat's thyroid tissue. They did not measure thyroid hormones production! Furtheromre, they used unrealistically high iodine tissue dosage, corresponding to an oral intake of 50 grams of Iodine a day (if it were done for humans)
This one study has became the basis of discontinuation of the time-proven previous iodine supplementation therapies in favor of treating thyroid disorders with thyroid hormonal supplements or with surgery.
*) Using Iodine in Potassium-Iodide (Lugol) solution, for both hypothyroid and hyperthyroid conditions. The claimed success rate was close to 90% of the cases!

Quote:
An increased iodine requirement as a result of significant changes in human nutrition rather than a decreased environmental iodine supply is suggested to represent the main cause of the iodine deficiency disorders (IDD). The pathomechanism proposed is based on the fact that serum concentrations of thyroid hormones, especially of trijodothyronine (T3), are dependent on the amount of dietary carbohydrate. High-carbohydrate diets are associated with significantly higher serum T3 concentrations, compared with very low- carbohydrate diets. While our Paleolithic ancestors subsisted on a very low carbohydrate/high protein diet, the agricultural revolution about 10,000 years ago brought about a significant increase in dietary carbohydrate. These nutritional changes have increased T3 levels significantly. Higher T3 levels are associated with an enhanced T3 production and an increased iodine requirement. The higher iodine requirement exceeds the availability of iodine from environmental sources in many regions of the world, resulting in the development of IDD.
