Do we still need to continue to eat iodized salt?

In recent years, more and more people have paid attention to iodized salt, and iodized salt has also been questioned, and the relationship between iodine and thyroid disease has also attracted people's attention. Can iodized salt still be eaten?

Iodine is a very important trace element for the human body, mainly synthesized with thyroid hormones in the body, and its physiological role is also manifested by the action of thyroid hormones. Iodine deficiency can cause simple goiter, and iodized salt prevents brain development backwardness caused by iodine deficiency in the human body and improves the quality of the people. In China, the IQ of the population increased by 12% after the promotion of iodized salt, while before that, the population lost 10% and 11% of the IQ due to iodine deficiency.

Although iodized salt has an intimate relationship with the quality and IQ of the human body, the relationship between thyroid disease and iodized salt is the topic we are most concerned about. In fact, there is still a risk of iodine deficiency in China, especially for pregnant women, who must ensure adequate iodine intake before and during pregnancy.

In recent years, the relationship between iodine excess and thyroid disease has attracted much attention, and it has even been reported that adding a little salt is the culprit of thyroid disease. There are also ** reports that counting patients with hyperthyroidism and hypothyroidism, there may be more than 200 million patients with thyroid disease in China. According to studies, the incidence of thyroid nodules in normal people is 24%, and the incidence of thyroid nodules in people with low iodine content in urine tests is 31%.

In fact, no association with thyroid disease has been found in areas with adequate iodine intake, and a study in Switzerland showed that the incidence of thyroid cancer decreases year by year after consumption of iodized salt. The World Health Organization considers the incidence of thyroid cancer to be lower in areas with adequate iodine intake than in areas with iodine deficiency.

Salt iodization must also be adhered to.

Universal salt iodization is the safest, most effective, least cost-effective and most long-lasting recommended method of eliminating iodine deficiency worldwide, with approximately 70% of households worldwide using iodized salt. The Institute of Iodine Deficiency Disease Prevention and Control of the Chinese Center for Disease Control shows that "although Chinese are no longer deficient in iodine in general, we must still insist on eating iodized salt."

In fact, many people don't know that the iodine we ingest can only stay in the human body for 100 days, so in iodine-deficient areas, people will have iodine deficiency again as long as they do not supplement iodine for 100 days. The reason why there is no shortage of iodine in our country in general is that we have been insisting on the compulsory consumption of iodized salt for more than 10 years.

In 2005, the World Health Organization set the iodine intake in China as "exceeding the appropriate amount", but "exceeding the appropriate" is not "excessive intake", that is, the health risk is very low. Because most of our country is a low-water and alkaline area, in general, the contribution of iodized salt to the prevention of iodine deficiency is much greater than that of iodine excess. There is no better treatment for iodine deficiency caused by the living environment, and it can only be prevented early.

Iodine is a trace element that all living things need, and humans are no exception.

If there is less iodine, you will get iodine deficiency, which can cause mental retardation, premature birth, miscarriage and congenital malformation of pregnant women, affect the normal development of the fetal brain, and endemic goiter and other serious consequences.

Before the 90s of the last century, China was one of the major countries with iodine deficiency, and for this reason, it also introduced a national iodine supplementation policy.

Therefore, iodized salt with a small amount of iodide was born, which is the safest, economical and effective way to prevent iodine deficiency.

1999 year. The results of the national iodine nutrition surveillance that year found that the urinary iodine level of children was 306 micrograms, which was at a high level. After discussion and demonstration, Chinese experts proposed for the first time in the world that reducing the urinary iodine level to less than 300 micrograms is an acceptable iodine nutrition level, which can not only provide enough iodine to the population, but also reduce the risk to the lowest level.

In 2000, China's iodine content in the production process was reduced from no less than 40 milligrams per kilogram to an average of 35 milligrams per kilogram. At present, the state is revising the "Regulations on the Management of Salt Iodization to Eliminate the Hazards of Iodine Deficiency" to treat people in different regions differently.

Not to mention whether it's necessary or not, the key is to give people the freedom to choose. For example, some people are deficient in calcium and iron. Why don't people advocate calcium and iron salts?

The whole country consumes iodized salt, and those who are iodine deficient will definitely consume too much salt. In fact, potassium iodate can be used as a medicine. People with iodine deficiency buy it themselves.

Continuing to eat iodized salt varies from person to person, and if you are an individual, you feel that you don't need iodization to choose iodine-free, which is still necessary for the whole country.

The National Health and Disease Control and Prevention Service released a national survey report on iodine levels in drinking water on May 7. The results of the survey show that the iodine content of water in towns and villages across the country is low, which is a natural environment iodine deficiency disease. Surveys show that Chinese residents in most areas should continue to consume iodized salt.

If you want to eat iodized salt, you can't eat iodized salt for people with hyperthyroidism, you can't eat it for people with thyroid disease, and it's not recommended for people in non-iodine deficiency areas. Iodized salt refers to the salt that has been added to the iodine preparation. That is, salt that adds a certain proportion of potassium iodate and an appropriate stabilizer to table salt for the exclusive consumption of people in endemic thyroid disease endemic areas.

The retail price of salt iodized remains unchanged and no salt tax is levied. Most of the salt with the word iodine on the market is iodized.

First of all, patients with hyperthyroidism, eating iodized salt will aggravate the condition, so it must not be eaten. This is followed by hypothyroidism due to autoimmune disorders, which require iodine intake. Of course, if the area itself contains a lot of iodine, it is best not to eat iodized salt, it is recommended to eat non-iodized salt to protect the body.

The vast majority of people need to consume iodized salt because most areas are deficient in iodine, which can lead to thyroid diseases such as Great Neck Disease. Patients with hyperthyroidism should not eat iodized salt often, and they should not eat too much if their blood pressure is too high.

Of course, it is necessary to eat this kind of salt and intake this element to make the body more balanced. Older people are not suitable for eating this salt because they have high blood pressure.

Edible salt iodization is good, and the specific analysis is as follows:

People get iodine mainly from drinking water, food, vegetables and the surrounding environment. If there is a lack of iodine in drinking water, food and the surrounding environment, people who live there for a long time will develop iodine deficiency diseases due to insufficient iodine intake; Iodine-deficient areas are not just inland, mountainous, steep slopes and high water tables;

The results of practice show that salt iodization is the most cost-effective, simple and easy way to prevent iodine deficiency diseases in the face of a large area of iodine deficiency and a large number of prevention and control objects. Salt is a necessity in people's lives, and iodization in salt can supplement iodine through three meals a day, which is convenient and can ensure that people consume a sufficient amount of iodine for life;

So it can be seen that iodization of edible salt is a good measure.

Whether to iodine or not to iodine depends on the amount of iodine you consume, because more or less iodine intake can cause some diseases.

Although China has a certain range of water-source high iodine areas, it is still a country with a general iodine deficiency in the natural environment, and the prevention and treatment of iodine deficiency diseases should be unremitting.

According to reports, iodine is an important raw material for the synthesis of thyroid hormones, and insufficient iodine intake can cause iodine deficiency diseases, including endemic goiter, endemic cretinism and other diseases that damage the growth and development of the body, especially the nervous system and brain development, and iodine deficiency can also lead to miscarriage, premature birth, stillbirth, congenital malformations, etc. Ode to silver.

The main food and drinking water for the human body's iodine intake is food and drinking water, and kelp and seaweed have the highest iodine content in seafood. Although iodine-rich foods such as kelp and seaweed are produced in coastal areas, the survey found that the local residents eat less frequently and less, and most of the residents have lower iodine intake than the intake recommended by international organizations and China, and there is a risk of iodine deficiency, and they still need to eat iodized salt.
