Iodine-rich foods and iodized salt can be consumed in moderation during the iodine ban. During the period of iodine restriction, it is sufficient to refrain from eating iodized salt and iodine-rich foods, such as kelp, seaweed, seafood, sea vegetables, and so on. The rest of the food can be eaten in moderation, such as: rice, noodles and other staple foods, beef, pork, lamb and other meats, apples, cherries, pears, carrots, cauliflower, celery and other fresh vegetables and fruits, and the choice of salt should be non-iodized salt. People who need to strictly prohibit iodine should also avoid the use of iodine contrast media and iodine-containing drugs (such as amiodarone). People who are prohibited from iodine should maintain a light and healthy diet, and keep their diet nutritious, balanced and comprehensive.
