Other foods that are iodine-rich are shrimp, shellfish, sushi and seaweed. Reduce the iodine in your diet if your doctor determines that your iodine levels are too high. In some cases, too much iodine overstimulates the thyroid and pituitary glands and can cause a goiter.
Rapeseed and canola, used to make oils, also contain goitrogens, as do peanuts, soybeans, cassava, spinach, kale, sweet potatoes, strawberries, pears and peaches. Goitrogenic foods can interfere with thyroid function; however, these foods only significantly affect thyroid function if your iodine intake is low. Cooking foods inactivates goitrogens and stops them from affecting your thyroid function, according to an article published in Toxins in September 2010.
