Iodine is one of the essential elements for the human body. In addition to iodized table salt, seafood, vegetables, fruits and other foods contain iodine.
1. Seafood: Seafood such as seaweed, kelp, fresh fish, sea cucumber, dried scallops and other seafood are rich in iodine, such as dried kelp in the iodine content of 24 mg / kg.
2. vegetables: such as spinach, celery, cabbage, green peppers and other vegetables also contain iodine, mostly 12 to 201 micrograms / kg.
3. fruits: iodine-containing fruits include bananas, cherries, oranges, persimmons, pineapples and so on.
In addition, chicken, lean pork, dried tofu, walnuts, pine nuts and other foods also contain iodine, iodine intake from food is the main source of iodine in the human body, iodine deficiency may cause goiter, fetal malformation, miscarriage and many other problems.
Since most of the inland areas of China are deficient in iodine, the iodine that the general population obtains from food and drinking water every day cannot meet the needs of the human body without additional intake of iodine-enriched foods. Therefore, with the exception of residents living in areas with high iodine content in water sources, who do not need to consume iodized salt, residents in all other areas should consume iodized salt.
However, it should be noted that patients suffering from hyperthyroidism or taking iodine-containing preparations need to avoid consuming iodized food under the guidance of a doctor, so as not to affect the treatment of the disease.
