Iodine is easily lost after heating, and the longer the heating time, the more components are lost. So try to add as much salt as possible when cooking. Don't fry iodized salt with vegetables in hot oil, and don't wash iodized salt. Iodine loses quickly in high temperature environment, so the salt pot should be placed in a cool place without direct sunlight or thermal radiation. Don't buy too much iodized salt at a time, or you will lose a lot of iodine in plastic bags for a long time.

Buy iodized salt packed in small plastic bags, printed with designated trademarks and labeled with iodized salt. Never buy smuggled salt or non (low) iodized salt at will. Commercially available iodized salt is usually packed in plastic bags. Iodine loses quickly in plastic bags. After buying it back, put it in glass or ceramic utensils in time and cover it tightly.
