Hypothyroidism Question

[TrulyMD]

---

Members don't see this ad.

A patient who has hypothyroid and been diagnosed with Hasimoto, recently asked me about Goitrogens (substances that suppress the function of the thyroid gland, and which can also cause an enlargement of the thyroid).

Does anyone have information on goitrogens? Has anyone else been asked about this?

Apparently, this patient has stopped eating peanut butter too since its listed as a goitrogen. Thanks.

There are natural goitrogens - they all either interfere with TSH, thyroid hormone production, or iodine -- effectively leading to gland hyperplasia. I think observation of these compounds lead to the development of synthetic "goitrogens" that we now use in the treatment of hyperthyroidism (eg: thionamides).
The goitrogens have diff mechanisms of action. The website "thyroidmanager.org" has a good chapter on them.
I'll cut/paste some of the foods they discuss:
almond seeds, cassava, sorghum, maize, millet, cabbage, kale, brussel sprouts, cauliflower, kohlrabi, turnip, rutabaga, mustard, horseradish, soybeans, cow's milk.
