After hanging around the Iodine forum for most of last year, it seems to be the consensus that green tea has fluoride and if you are trying to avoid fluoride as I am, then I prefer to stay away from green tea.
Being in Australia, I don't buy anything from Dr. Mercola's website, but do get his regular newsletter and read probably 1 or 2 articles out of 10. I take from it what I need and leave the rest.
I have no doubt that he is trying to make a dollar, but then again, who isn't.
