Could a food decrease your tsh?

TSH: Tsh decreases in response to thyroid activity. If you're exposed to foods which suppress your thyroid and then avoid them, your thyroid function could normalize -- making your TSH decrease too. Some potentially problematic foods for thyroid include any containing bromine or bromates -- these can be found in breads, pesticides on fruits, soft drinks, etc. http://tinyurl.com/ntnqfpb.
