Then it is a rather well documented myth:

Rink, T., Schroth, H.J., Holle, L.H. and Garth, H. (1999). Effect of

Iodine and Thyroid Hormones in the Induction and Therapy of Hashimoto’s

Thyroiditis. Nuklearmedizin. 1999.; 38(5):144-9. in PubMed online.

" Iodine: an environmental trigger of thyroiditis, " Rose N.R. Bonita R.;

Burek C.L., Autoimmunity Reviews, Volume 1, Number 1, February 2002 ,

pp. 97-103(7).

Summary:

• Chronic lymphocytic thyroiditis (CLT) is a multifactorial autoimmune

disease with genetic and environmental factors contributing to its

development.

• The best-defined environmental factor is dietary iodine.

• Poorly-iodinated thyroglobulin is not well recognized by peripheral

blood lymphocytes (PBL) from patients with CLT.

• Iodination of thyroglobulin promotes recognition and proliferation by

patients’ PBL.

Canada's federal health agency issued a warning in 2003 for people with

Hashimoto's to stay away from kelp, because you might get as much as 4

mg per day by following the directions:
