Very informative - thanks. Regarding DIM - I have a healthy respect for cruciferous veggies. For about a year before I began having "problems" I had been eating raw broccoli and raw cauliflower and cabbage almost every day, thinking I was helping myself. Instead I think it was contributing to my Iodine deficiency. Although had been taking kelp daily for years, I think the all the raw veggies from the cabbage family pushed me over the edge (also some medications I took containing bromides).
Anyhoo, when I first learned that the cruciferous family is goitrogenic, I was somewhat panic stricken. I am still somewhat leery of those veggies, and seldom eat them raw. I do eat them cooked from time to time, though not with the same frequency as before. (I used to have them, as I said, daily and raw.)
I also take MSM - which I am thinking provides some of the benefits without the goitrogenic properties. Hope I'm right about that.
