A letter to a friend who practice natural medicine in USA

I correspond with my friend, a naturopath in the United States. We write about everything, and finally I asked her about the American naturopath's approach to iodine, related to their practice. Her answer surprised me. Here is my answer to her ... in English. When I have more time, I will translate the letter to "scandinavian" but if there is someone who want to help with the translation, please do.
