These foods contain substances called goitrogens, which can interfere with the absorption of iodine, an essential mineral for the production of thyroid hormones.
Raw cruciferous vegetables: Cabbage, broccoli, cauliflower, kale, turnip, radish, and Brussels sprouts. While moderate consumption when cooked is not problematic, large quantities and raw consumption can impair thyroid function.
Soy and soy products: Tofu, soy milk, and edamame can affect iodine absorption and the conversion of T4 to T3, the active thyroid hormones.
