Goitrogenic - from the Internet:
Goitrogenic foods like brussels sprouts, rutabaga, turnips,
cauliflower, African cassava, millet, babassu (a palm-tree coconut
fruit popular in Brazil and Africa) cabbage, and kale can act like the
antithyroid drugs propylthiouracil and methimazole in disabling the
thyroid function, so they should not be eaten in large amounts by
someone on thyroid hormone replacement who still has a thyroid.
It's thought that the enzymes involved in the formation of
goitrogenic materials in plants can be destroyed by cooking, so
thorough cooking may minimize goitrogenic potential.
