Something to think about. Bromine (in bread in USA) & chlorine (in our water) displace iodine in our thyroids causing inadequate function. As an aside, I'm recovering from the effects of being poisoned by pharma drugs (30 years antidepressants, four months chemo/steroids, five months lupron, nine months duloxetine), all of which caused brain & organ damage: And then I got even worse brain & organ damage from stopping them all - these synthetic poisons take up residence in our bodies, we change physiologically, & we end up not being able to survive without them. Google all your meds with "danger" afterwards. If you ever stop a med, research first & prepare your body so you don't suffer the physical & emotional damage I have. I almost died several times & the docs all just shook their heads at me (my bloods aren't "that bad," forget that I can't tolerate anything but steamed vegies, sleep 3 - 6 hours/night, can't breath, dehydrated, etc.) & pushed more antidepressants & antihistamines at me. Worthless, the lot of them.
