How do goitrogens affect the thyroid?
Goitrogens, including cruciferous vegetables and soy product, have been shown to inhibit thyroid hormones synthesis in several ways, mostly by inhibiting iodine utilisation. Those micronutrients have to be taken in consideration specially in those with thyroid diseases or who are iodine deficient.
Is milk a goitrogenic?

Are onions goitrogenic?
Onions. Onions contain two different goitrogens: quercetin and propyl disulfide. Quercetin reduces the activity of thyroperoxidase as well as the activity of a second enzyme — hepatic deiodinase — a liver enzyme required to activate the thyroid hormone.
Is soy a Goitrogen?
Summary. The observations of Sharpless, Pearsons and Prato that soybeans are goitrogenic, that this goitrogenicity is partially inactivated by heat, and that iodine will counteract the effect on the thyroid gland have been corroborated.
