I read that as a lot of iodine all at once in iodine deprived individuals can cause havoc until iodine sufficiency (over 10 years) is obtained. As for the rest of the article, it's mainly talking about autoimmune thyroiditis, with effects occuring mainly in PREVIOUSLY IODINE DEFICIENT subjects. Hmmmm. Then it discusses cancer. And I do understand their overall conclusions: Quote: . The frequency of cytologically diagnosed chronic thyroiditis increased from 1.5 to 5.7% (214). Overall, it appears that correction of iodine deficiency decreases the risk of, and the morbidity from, thyroid cancer.
Thus, the benefits of correcting iodine deficiency far outweigh its risks (215, 216). Iodine-induced hyperthyroidism and other adverse effects can be almost entirely avoided by adequate and sustained quality assurance and monitoring of iodine supplementation which should also confirm adequate iodine intake. Endquote.
I guess the only real bone of contention here are the amounts given. (10 years to recover from deficiency and let iodine supplementation settle into acceptable levels??? I'm sorry, but I doubt if I can spare a decade at my age.)
