Hidden Thyroid Blockers

Food products worth paying attention to:

• Raw kale, spinach, broccoli, cabbage, Brussels sprouts, cauliflower, pak choi

These cruciferous vegetables contain   goitrogens   — compounds that can   interfere with iodine absorption   by the thyroid gland.

Iodine is essential for the production of thyroid hormones (T3 and T4).
Iodine blockage by goitrogens can   worsen hypothyroidism   and lead to   goiter   (enlargement of the thyroid gland).
