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.
In addition, there are a few other foods not included in these categories such as peaches, strawberries, peanuts, radishes, spinach and millet that also contain goitrogens. Isoflavones such as genisten in soy products block thyroid hormone by blocking an enzyme responsible for adding iodine to the thyroid hormone. A second category of foods associated with low thyroid production is the cruciferous food family.
