getting goitrogens out of your system

[uksweetheart]

Hi, I developed hypothyroidism after having radiotherapy to my larynx for cancer 13 years ago, I've been on Levothyroxine for many years and it's helped keep everything under control. 2 weeks ago I ate a lot of peanuts not know they have goitrogens in them and can throw your thyroid out of whack, I am now suffering it from palpitations and was hoping someone could tell me how log does it take for goitrogens to get out of your system or is there anything I can do to help it?

Generally, if we have a thyroid, unless we are iodine deficient (not likely), we are unlikely to experience any problem from ingesting goitrogens in reasonable amounts and/or from time to time. With adequate levels of iodine in our diet, the thyroid gland can, for the most part, manage a diet that includes goitrogenic foods. Soy is the exception as apart from being goitrogenic, it can also interfere with the absorption of thyroid hormone replacement meds. However, If we are hypothyroid due to thyroid surgery or due to radioactive iodine treatment for Graves' disease, we don't need to be especially particular about goitrogens - part of their effect is to block the process by which iodine becomes the key thyroid hormones thyroxine and triiodothyronine; and to inhibit the release of thyroid hormone by the thyroid gland, neither of which is an issue if we don't have a thyroid. Is there a possibility that inadequate dosing/serum hormone levels could be the culprit?
