just read in the nutritional healing guide ,third edition, that if you suffer from hypothyroidism than the followings foods should be avoided: broccoli,brussel sprouts,cabbage,kale,mustard greens peaches,pears,radishes,spinach and turnips
( note: people suffering from hyperthyroidism should include the above mentioned foods to lower thyroid hormones )

foods that help with hypothyroidism : apricots,dates,egg yolks,molasses,parsley,potatoes,prunes raw seeds,chicken ,raw milk,and whole grains.

I started eating cabbage and broccoli about three weeks ago and have been feeling worse ,maybe another piece of the puzzle for me ?
