The physiological function of iodine is relatively simple, mainly involved in the synthesis of thyroxine in human body. The physiological function of iodine is manifested by the action of thyroxine, which participates in the metabolism of protein, carbohydrate, fat and energy in human body and promotes growth and development, especially brain development. Therefore, if the human body lacks iodine, it will indirectly affect health and even lead to iodine deficiency.
Including endemic goiter, endemic cretinism, endemic subclinical cretinism and other diseases that damage the growth and development of the body, especially the development of the nervous system and brain. At the same time, iodine deficiency can also lead to miscarriage, premature delivery, stillbirth and congenital malformation.
Extended data
Preventing iodine deficiency and supplementing iodine is the key. Eating iodized salt can quickly and conveniently supplement most of the iodine needed by human body. Xu explained that taking a healthy adult as an example, the recommended daily iodine intake is 120 micrograms.
According to the 20 16 version of Dietary Guidelines for China Residents, the recommended daily intake of salt is 6g. If a healthy adult eats 6 grams of iodized salt every day, he can consume 108~ 198 micrograms of salt every day.
In addition, eating foods rich in iodine also has a good auxiliary function, such as kelp, laver, mussel, dried clam, scallop, sea cucumber, jellyfish, Nostoc flagelliforme and so on. Xu explained that most marine organisms that can be used as food contain relatively more iodine, and choosing these foods is conducive to preventing iodine deficiency.
