Two types of foods may affect thyroid health: 1. Those containing iodine and 2. Those containing substances called goitrogens. Your thyroid needs iodine to produce the many types of thyroid hormones, while goitrogens inhibit thyroid function. You’ll find loads of iodine in seaweeds and Lifestream Spirulina.
Goitrogenic foods include cruciferous vegetables – broccoli, cabbage, Brussels sprouts, radishes, and cauliflower. Rapeseed and canola, used to make oils, also contain goitrogens, as do peanuts, soybeans, spinach, kale, sweet potatoes, strawberries, pears and peaches.
Goitrogenic foods only significantly affect thyroid function if your iodine intake is low, and cooking these foods inactivates goitrogens and stops them from affecting your thyroid function.
