May 15 is the national iodine deficiency awareness day. Yesterday morning, the Municipal Center for Disease Control and Prevention carried out the 23rd “National Day for the Prevention and Treatment of Iodine Deficiency Disorders†square publicity and consultation activities. In recent years, monitoring has found that Yangzhou, as a region with mild iodine deficiency, has a hidden danger of iodine deficiency. Last year, residents of the city consumed more than 20,000 tons of small-package iodized salt, which is basically in a balanced state compared with previous years. Experts remind that scientific supplementation of iodine must be done in addition and subtraction, pregnant women and children need iodine supplementation, and hyperthyroidism and other groups need to reduce iodine intake.
Prevent iodine deficiency
Yangzhou people ate more than 20,000 tons of iodized salt last year
Monitoring data in recent years have found that Yangzhou has a hidden danger of iodine deficiency as a region with mild iodine deficiency. Yesterday, at the site of a publicity event held in the community square of Jiuwang Township in Tangwang Township, Yin Wenping, Director of Salt Administration Department of the Municipal Salt Administration, told reporters that last year residents of the city consumed more than 20,000 tons of small-package iodized salt. "Compared with previous years, the consumption of iodized salt tends to balance."
Why consume iodized salt? Tang Yan, director of the Municipal Center for Disease Control and Prevention, said that iodized salt can effectively eliminate iodine deficiency disorders. It is reported that iodine deficiency disease is the general term for a series of diseases that occur due to the lack of iodine in the external environment and the lack of human iodine intake. "However, according to monitoring, the incidence of iodine deficiency disorders in our city has dropped below 0.5%."
It is reported that forced salt iodization to prevent iodine deficiency disorders has been implemented for nearly 20 years. The Chinese do not lack iodine in general, but it is impossible to eliminate iodine deficiency once and for all. Tang Yao introduced that because the intake of iodine in the human body can only stay for 100 days, 100 days without iodine deficiency will again be lacking. "So we have to continue taking iodized salt, and eating about 6 grams of salt per person per day will satisfy the body's demand for iodine, but eating too much will cause chronic diseases such as high blood pressure, so it's usually possible to control it with salt-limited spoons."
Iodine reminder
Pregnant women and children need to do iodine "addition"
Tang Hao pointed out that the special groups of pregnant women, infants, and children with hyperthyroidism should do a good job of adding and subtracting iodine. In addition to daily salt iodine supplementation, it is also possible to increase the body's iodine content by ingesting seafood. In contrast, hyperthyroidism patients want to reduce the intake of iodine.
“Iodine modulates the body's metabolism and growth through the synthesis of thyroid hormones, and especially affects the brain's development and intelligence levels.†Wang Fuzheng, head of the schistosomiasis control department of the Disease Control Center of Hanjiang District, said that pregnant women need iodine more than the average person, and iodine deficiency in pregnant women can cause fetal abortions. Preterm birth, stillbirth, and congenital malformations. Causes of pregnant women susceptible to iodine deficiency, first, iodine intake to meet the dual needs of their own and the fetus; Second, pregnant women due to pregnancy reactions, edema, pregnancy-induced hypertension, etc., reduce the intake of salt and lead to reduced iodine intake .
Experts suggest that infants under 4 years of age need 70 micrograms of iodine per day, adults need 150 micrograms per day on average, and pregnant women and nursing mothers need about 200 micrograms per day.
Iodine deficiency in children can lead to mental retardation, short body, lack of iodine deficiency in adults, body edema, resulting in endemic goiter, commonly known as "big neck disease."
In addition, experts from the Municipal Center for Disease Control and Prevention reminded members of the public to purchase iodized salt in plastic bags with a designated trademark and an iodized salt mark when eating iodized salt. Do not purchase salt or salt without iodide; iodine The salt should be properly preserved, it should not be stored for a long time, and it should be bought with food; when it is cooked, the salt is best.
Expert Q & A
Increased thyroid disease is not necessarily associated with iodized salt
In recent years, thyroid diseases have been reported at home and abroad. A reader asked: If there is an increase in the number of thyroid diseases, shouldn't we eat iodized salt? A breast surgery specialist said that at present, there is no scientific evidence that the increase in the incidence of thyroid disease is directly related to the consumption of iodized salt.
Thyroid diseases are on the rise. There are two main reasons: Thyroid diseases are related to changes in the environment, diet, lifestyle, and mental stress. The rate of people attending the health service and health checkups has increased significantly, especially high-resolution ultrasounds and high-resolution ultrasounds. Sensitive hormone assays have been widely used in clinical practice, which has greatly improved the early diagnosis of thyroid diseases.
"China's iodine content standards have been scientifically determined. Except that a small number of patients with hyperthyroidism should control iodine intake, the consumption of iodized salt in the normal population will not cause high iodine hazards." Experts said that the safety value of iodine is very broad, the daily intake of iodine Iodine levels range from 50 to 1000 micrograms, so people do not need to worry about iodized salt.
