Here's some info on thyroid health:

Thank you for your reply. Just to be clear, what these articles are saying is basically that if I have delicate thyroids, I should not put raw kale or other cruciferous veggies into my nutribullet shakes, right? Perhaps it is advisable for your Nutribullet recipe book to make a note of it to avoid misunderstanding. I want to suggest this because kale has become such a popular veggie that everybody is eating it raw. Now my second question is, can I eat kale cooked, like in a soup made with my Nutribullet RX?
Chris8, cooking may help to inactivate some of the potentially goitrogenic substances found in food so yes, cooking kale/broccoli/brussels sprouts/etc. would be a good idea.
