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.
Enlargement could also occur with normal production of thyroid hormone, such as a nontoxic multinodular gland. Another type of thyroid growth, called a sporadic goiter, can form if your diet includes too many goiter-promoting foods, such as soybeans, rutabagas, cabbage, peaches, peanuts, and spinach. Keep in mind you would have to eat huge amounts of these foods to cause a goiter.
