The important role of iodine
When iodine is deficient, the synthesis of thyroxine is blocked, which leads to a series of biochemical disorders and abnormal physiological functions. When iodine deficiency is moderate, due to the influence of thyroxine synthesis, the thyroid gland compensatory increases, thus causing endemic goiter.
Severe iodine deficiency can lead to growth stagnation, mental retardation, abnormal skin and hair structure, mental retardation and even dementia and deafness, resulting in cretinism. Therefore, in some mountainous areas and other iodine-deficient areas, it is very important to prevent and treat iodine deficiency in infants. The content of iodine in food varies, and seafood is the most. Generally speaking, because drinking water in coastal areas also contains some iodine, and seafood is often eaten, there will be no iodine deficiency. There is no iodine supply standard in China. American standards are: 40 micrograms per day for infants from June to June, 50 micrograms per day for infants from June to June, and 70 micrograms per day for infants aged 0-3.
The content of iodine in human body is 20~50 mg, of which 20~30% is stored in thyroid and the rest is stored in muscles and other tissues.
Iodine in water and food mostly exists in the form of inorganic iodine compounds, which can be directly absorbed by the intestine, and most of it is used by the thyroid to form thyroxine. Most thyroxine binds to glucuronic acid in the liver and enters the intestine with bile, of which about 1/3 is reabsorbed and the rest is excreted from feces.
Iodine is the main raw material for human body to synthesize thyroxine. Thyroxine can regulate the metabolism of three nutrients (protein, fat and sugar) and heat energy metabolism.
Eating too little iodine will make infants with congenital thyroid dysfunction, which may lead to mental retardation, dementia, short stature, hearing loss, skeletal retardation and edema. Therefore, mothers should eat more iodine-containing foods during pregnancy and lactation to meet the needs of babies.
Iodine mainly comes from seafood, such as kelp, seaweed, jellyfish, hairtail and so on.
Main manifestations and hazards of iodine deficiency disorders
1, iodine deficiency leads to mental retardation, stupidity, idiocy, and other mental disabilities.
2. Iodine deficiency leads to endemic goiter and hypothyroidism.
3. Severe iodine deficiency can lead to endemic cretinism, mainly in fetus and infancy. The patient is stupid, short, deaf and paralyzed and presents a particularly ugly face.
4. Iodine deficiency in pregnant women can lead to premature delivery, abortion, stillbirth, congenital malformation, children in congenital deafness, etc.
5. When iodine deficiency is not serious, although there are no typical symptoms of cretinism, there are still mental retardation or developmental retardation, which is called subclinical cretinism.
