Question 2: Is it necessary to eat iodized salt? It is necessary for inland people to read the attached answer. Iodine mainly exists in marine products, such as kelp and laver, which are rarely eaten in inland areas, so it will cause iodine deficiency. The state adds iodine to salt to improve people's iodine nutrition. People in coastal areas are not short of iodine and need not eat iodized salt.
Question 3: Is it necessary to eat iodized salt? Explain briefly the function of the first paragraph. Iodized salt is really necessary and has a certain effect on preventing iodine deficiency.
Question 4: Is it necessary to eat iodized salt? How to supplement iodine scientifically is completely unnecessary. Now people in China are not short of iodine, but have been supplemented with excessive iodine. But why does the country make iodized salt? There is a big interest chain involved. The profit of iodized salt is more expensive than that of non-iodized salt, but the cost increases little. In order to maintain high profits, vested interests have been preventing the normal production of edible salt, so the salt without iodine in the market is more expensive than the salt with iodine, because it is difficult to buy. You can find relevant in-depth analysis in Baidu, and there are some. Because of the iodine excess of the whole people, there have been many diseases caused by iodine excess! Excessive iodine is more harmful than iodine deficiency.
Question 5: It is necessary for southerners to eat iodized salt, but it is not necessary.
If iodine is deficient, iodized salt is needed. You don't need it if you don't need it. Now, except for the iodine deficiency in remote mountainous areas. There is no shortage of city people. Non-iodized salt can be used. If you are satisfied, please click Useful.
Pay attention to the following points when eating iodized salt: 1. Residents in iodine-deficient areas must eat iodized salt scientifically and for a long time, otherwise once iodized salt is stopped, iodine deficiency disorders will recur; 2. Don't buy too much iodized salt every time, because iodine volatilizes for a long time; 3. The iodized salt container should be covered and placed in a dry, cool and high temperature place; 4. Add iodized salt when cooking. Do not use iodized salt frying pan, stew for a long time, cook for a long time, because iodine is volatile.
Question 6: Does Guangzhou still need to eat iodized salt? You are not an alien. Why don't you eat it?
Question 7: What is non-iodized salt? Who needs to eat non-iodized salt? Non-iodized salt, as its name implies, is a salt without iodine.
Professor Wu Yijie, head of Shanghai Thyroid Group of Chinese Medical Association and chief physician of endocrinology department of Shanghai First People's Hospital, pointed out that iodine deficiency can lead to hyperthyroidism (commonly known as big neck disease), but iodine supplementation should be scientific and reasonable. Iodine intake is not the more the better. If people consume too much iodine, it may also cause harm, such as iodine goiter and other diseases. Due to factors such as high work pressure and accelerated pace of life, there are more and more patients with thyroid diseases such as hyperthyroidism in bed in recent years. For people who already have hyperthyroidism or have a family history, to control excessive iodine intake, iodine-free salt should be eaten. At the same time, he also pointed out that at present, the number of patients with rhinitis in China is increasing gradually, and non-iodized salt should also be used to wash the nose with normal saline.

In order to avoid excessive iodine, it is suggested that the following people should eat non-iodized salt instead of iodized salt:
1. Residents in non-iodine deficient areas should not eat iodized salt, especially in coastal areas like Changhai County, which eat a lot of seafood (rich in iodine).
2. Hyperthyroidism patients, both men and women, because iodine can synthesize thyroid hormone.
3. Urban residents with thyroid nodules found in physical examination (because most cities have eliminated the "big neck disease"-endemic goiter caused by iodine deficiency, when urban residents find thyroid nodules, the possibility of iodine deficiency is extremely small, and the possibility of iodine excess is very high).
4. In patients with thyroiditis (Hashimoto's disease), iodine will aggravate inflammation.
5. Patients with thyroid tumors (whether they have had surgery or not).
There were 6 cases of thyroid cancer (except those who had undergone total thyroidectomy).
7. Patients with hypothyroidism have been controversial, but now they tend to limit iodine intake.
8. Other thyroid diseases (in fact, there is only one thyroid disease-big neck disease needs iodine supplementation, and other thyroid diseases do not need iodine supplementation, otherwise it may be counterproductive).
Question 8: Do I need iodized salt to live in Singapore? No I don't.
Question 9: Is it better for children to eat iodized salt or non-iodized salt? The iodine content of salt has been adjusted three times. In response to this problem, Chen Zupei, the head of the expert advisory group on iodine deficiency disorders of the Ministry of Health and the project leader of the iodine content standard of edible salt (draft for comment), said that the iodine nutrition status of residents in most areas of China is at an appropriate and safe level, except in areas with high iodine content in water. Statistics show that the iodine content of salt in China has room to be lowered, but only slightly, not drastically. In addition, he also said that China has adjusted the iodine content of salt three times, and this will be the fourth adjustment. Each adjustment is based on national monitoring data, and it is possible to make adjustments in the future. The reporter saw in the Notes on the Compilation of Iodine Content in Edible Salt (Draft for Comment) that the first adjustment of iodine content in table salt was 1996, which stipulated that the upper limit of iodine content should not exceed 60 mg/kg. This regulation is based on the national iodine nutrition monitoring results of 1995. Because there is no upper limit for the iodine content of salt, the iodine content of salt in some areas is too high, and some of them are as high as 100 mg/kg, so it was adjusted at that time. The second adjustment was made at 1997. The results of national iodine nutrition monitoring in that year showed that the urinary iodine level of children was 330 μ g/L, suggesting that the urinary iodine level of children increased obviously, which was caused by excessive iodine supplementation for key populations (indiscriminate use of iodized health products and iodized oil pills). The Ministry of Health promptly asked most areas where the iodized salt coverage rate has been greatly improved to stop taking iodized oil pills, and at the same time put forward the principle and slogan of "scientific iodine supplementation". The third adjustment was made at 1999. The results of national iodine nutrition monitoring found that the urinary iodine level of children was 306 μ g/L, which was on the high side. After discussion and demonstration, Chinese experts put forward for the first time in the world that reducing urinary iodine level below 300 μ g/L is an acceptable iodine nutrition level, which can not only provide enough iodine for the population, but also minimize the risk of side effects. In 2000, China reduced the iodine content in the production process from no less than 40 mg/kg to an average of 35 mg/kg. To this end, Chen Zupei said that through adjustment, in the two national iodine nutrition monitoring in 2002 and 2005, the urinary iodine level of children decreased to 24 1 μ g/L and 246 μ g/L respectively, reaching an acceptable level. In addition, it is also reported that the appropriate standard of iodine nutrition level for the general population put forward by the World Health Organization is that the median urinary iodine is between100μ g/L and 200μ g/L, and the iodine deficiency standard for pregnant women is less than150μ g/L. A survey in China's coastal areas in 2009 showed that the median urinary iodine of adults, nursing mothers and children in Shanghai and other coastal areas. Liaoning, Zhejiang and Fujian are in the range of 100μg/L ~ 250μg/L, and the iodine nutritional status is generally suitable and safe, but the proportion of individuals with low urinary iodine level is high, especially pregnant women, whose urinary iodine level is below150μ g/l. Then, in many provinces, autonomous regions and municipalities in China, where is iodine high and where is lacking? "Iodine Content of Edible Salt (Draft for Comment)" made the following statistics: About five provinces, autonomous regions and municipalities (Anhui, Henan, Hubei, Guangxi and Yunnan) are in the over-standard level; 16 provinces, autonomous regions and municipalities (Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Jiangsu, Jiangxi, Shandong, Hunan, Chongqing, Sichuan, Guizhou, Shaanxi and Ningxia) are above the appropriate level; Only nine provinces, autonomous regions and municipalities (Heilongjiang, Shanghai, Zhejiang, Fujian, Guangdong, Gansu, Qinghai, Xinjiang and Xinjiang Construction Corps) are at an appropriate level. So there is room for downward adjustment. Professor Guo Qiyu, chief physician of China Navy General Hospital, pointed out that the purpose of compulsory iodization of salt is to eliminate iodine deficiency disorders. However, with the development of society, iodine deficiency no longer exists in many areas, and excessive iodine supplementation is also common. Therefore, it is very necessary to reduce the fortified amount of salt iodine. Professor Wei Dai Xin, an endocrinologist at Peking Union Medical College Hospital, also said that the biggest highlight of this revision is to set a floating range for the standard of iodine content in iodized salt, that is, "all provinces, autonomous regions and municipalities directly under the Central Government choose the average iodine content of edible salt suitable for local people according to the actual iodine nutrition level of the population; The allowable range of iodine content in edible salt is 30% of the average iodine content. " In addition, he also pointed out that due to the continuous improvement of people's living standards in China, the way of iodine intake is gradually increasing. & gt
Question 10: The baby needs iodine. Should I continue to eat non-iodized salt or iodized salt? It is a national policy to prevent big neck disease. But this policy has not been adjusted according to people's diet now. The existing living conditions enable the human body to obtain the iodine it needs from various sources, and iodized salt is not suitable for many areas. Look at your usual eating habits. If you often eat seafood, such as kelp, in order to ensure that your body will not lack iodine, you can not eat iodized salt. If seafood is not often used, it is recommended to buy iodized salt.
