iodine deficiency disorders are caused by low iodine intake, but excessive iodine intake will also affect the health of the body. The harm of excessive iodine intake to human health mainly includes the following aspects:

1. The most common effects of high iodine on thyroid function are iodine-induced goiter (IH) and iodine-excess hyperthyroidism.

2. The influence of high iodine on intelligence The relationship between excessive iodine and intelligence has only attracted the attention of experts and scholars in recent years. A number of epidemiological surveys in the population show that the IQ of students in high iodine areas is significantly lower than that in iodine-suitable areas. Most animal experimental studies have also proved that excessive iodine load can indeed reduce the weight of animals' brains and reduce their learning and memory, although this effect is not as obvious as that of iodine deficiency.

3. The influence of high iodine on sexual function. A study in the United States once showed that the intake of iodized salt had a certain relationship with the male * * * count, suggesting that Americans' consumption of iodized salt may lead to a decrease in the male * * * count. Composition on the lack of iodized salt

Questions about iodized salt Today, the composition assigned by the teacher is an essay on "iodized salt". I don't quite understand it. When I got home, I asked my grandmother, who said that iodized salt is the salt containing micronutrient iodine.

So what is iodine? Iodine is an essential micronutrient for human body.

Eating iodized salt can effectively prevent iodine deficiency disorders, commonly known as "big neck disease".

The biggest harm of iodine deficiency disorders is to make infants' brains backward, mentally retarded, and even stupid, dull and stupid. Iodine deficiency can hinder women's reproductive function, causing infertility, abortion, stillbirth, fetal malformation, etc. Iodine deficiency can also reduce the work, learning ability and labor efficiency of adults and adolescents.

The iodine needed by human body can be obtained through diet such as water, grain, vegetables, meat, poultry, eggs and milk.

most places in China are short of iodine, so we should insist on eating iodized salt all the year round.

So the country enforces iodized salt, which is why most of the things we see in supermarkets are iodized salt.

excessive iodine intake is also harmful to human health.

There are two groups of people who can't eat iodized salt. They are people in high iodine areas and people who can't eat iodized salt because of treating diseases (such as thyroid diseases).

China's "Regulations on the Administration of Iodized Salt to Eliminate the Hazards of Iodine Deficiency Disorders" clearly stipulates that these two groups of people can buy iodized salt in the shops specially set up by the salt industry department. I write a composition of 4 words

On Friday, Mr. Chen showed us a video about Iodine Deficiency Disorder.

iodine is an indispensable and rare element in human body.

In iodine-deficient areas, many people get big neck disease, which is the consequence of iodine deficiency.

When pregnant women lack iodine, it is likely to lead to miscarriage.

Even if children are born, they are physically unhealthy, and most of them may even be mentally retarded.

Looking at the faces with some dementia, my empty eyes looked numbly ahead, and there was no emotional fluctuation in my eyes.

I can't help feeling a little sad. God gave them the body in their lives, but not the soul.

without the ability to take care of themselves, they are like cold machines, walking dead.

it doesn't mean anything to them to live.

have ears but can't understand anything; Have eyes but can't understand anything; Have a mouth but can't explain anything; Have a brain but don't know what to think; There is life but I don't know what to pursue.

Without dreams, they always seem to be inseparable from their parents who raised them from childhood.

Finally, iodized salt was produced. These iodized salts, which were not distributed to high iodine areas, saved the lives of countless children.

We are lucky. We have pursuit and running in life, and we can learn everything as soon as we learn.

Every pair of eyes is bright, with wisdom, emotion and dreams.

The limbs are also very healthy, and they have a clear consciousness and clear thinking.

Maybe some people will only sympathize with those who are not sound. In fact, we deserve more sympathy, because our brains are rusty because they are not used all the year round.

If you want not to lose yourself on the road of life, you must first learn to chase and run in life, and your thoughts will never stop. The composition of 3 to 4 words about iodine is urgent!

China is a country with serious iodine deficiency, and iodine deficiency areas are widely distributed, involving almost the whole country; The population threatened by iodine deficiency disorders is very large, involving almost everyone in the whole society, men, women and children without exception.

The areas with the most serious iodine deficiency disorders are generally remote, inaccessible and backward in economy and culture.

Moreover, iodine supplementation must be persisted for a long time, from generation to generation, or people living in iodine-deficient areas will suffer from iodine deficiency if they don't get enough iodine for six months.

in view of the above-mentioned national conditions, in order to eliminate iodine deficiency disorders in China, we must find a convenient, economical, safe and effective iodine supplement measure, which is suitable for the needs of the whole country and all the people.

In the struggle against iodine deficiency disorders, human beings have found a method to prevent iodine deficiency disorders by eating iodized salt, which has been used for more than 1 years.

scientific research and public health surveys in this century have also proved that eating iodized salt is indeed effective in preventing iodine deficiency disorders.

Since 1948, international organizations such as UNICEF, FAO, WHO and the International Committee for the Control of Iodine Deficiency Disorders have strongly supported the prevention and treatment of iodine deficiency disorders, and advocated iodized salt as the basic method for the prevention and treatment of iodine deficiency disorders.

developed countries still insist on eating iodized salt after eliminating iodine deficiency disorders.

For example, in the United States, France, Canada, Japan and so on, people have a deep understanding of the harm of iodine deficiency and a strong sense of self-care because of their high cultural quality.

Although iodized salt and non-iodized salt are sold at the same time in these countries, the market of iodine-rich foods and health products is very active at the same time, and people who eat non-iodized salt can also get the iodine they need from other ways.

salt iodization is the most fundamental measure to prevent and treat iodine deficiency disorders.

This is proved by the prevention and control work in many countries for nearly a century, and it is the best method among various iodine supplementation methods. It is not only safe, effective, economical and easy to popularize, but also meets the requirements of trace, long-term and daily life.

But iodine is a very active substance, and the iodine in salt will be lost with the increase of storage time, resulting in less and less iodine content.

Therefore, we should pay attention to the following matters in use to ensure the maximum effectiveness of iodized salt.

1. Pay attention to the method of preserving iodized salt.

put iodized salt in a glass or ceramic jar with a lid, and put the jar in a cool place without direct sunlight, so as not to heat the salt as much as possible.

When iodized salt is stored at high temperature, the loss of iodine is faster than when it is stored at low room temperature.

Therefore, the method of preserving iodized salt should be scientific.

In addition, don't buy too much salt at a time, or you will spend the price of iodized salt but not get iodine.

2. Pay attention to cooking methods.

when cooking, we are used to adding salt first, but iodine will evaporate when it is heated.

Therefore, salt should be added as far as possible after cooking, and iodized salt should not be added to hot oil and fried with vegetables.

3. Pay attention to the amount of salt you eat.

According to the standard of iodized salt in China, each person can get about 12 micrograms of iodine by eating 6 grams of salt every day, which can fully meet the physiological needs of most adults.

pregnant or lactating women, infants and other people with special needs need more iodine than ordinary people.

Therefore, it is suggested that pregnant women, lactating women, infants and other people with special needs should take iodized oil pills or often eat seafood such as kelp and laver, so that they can not eat more salt but also supplement appropriate iodine. Iodine is one of the essential trace elements for human body, and iodine deficiency is very harmful to human health, especially serious iodine deficiency, which will cause a series of diseases, mainly goiter, cretinism, subclinical cretinism and so on.

In order to improve people's understanding of the prevention and treatment of iodine deficiency disorders, China has designated May 15th as the prevention and treatment day of iodine deficiency disorders every year, and this year's theme is "scientifically supplementing iodine, protecting intelligence and realizing dreams".

iodine deficiency disorders can be prevented. If you take a little iodine every day, you will be healthier.

"Iodine is one of the important trace elements that affect intellectual development. Iodine deficiency in human body will cause different degrees of damage, leading to iodine deficiency, or even disability.

"Zhong Jingjun, chief of the mission department of the county CDC, said that pregnant women should not be short of iodine in particular. Lack of iodine in their diet during pregnancy may lead to premature delivery and miscarriage, and the children born may suffer from congenital malformation, congenital deafness and other diseases.

If iodine deficiency is serious, it will lead to fetal brain development disorder. After birth, the child will be deaf, dumb, stupid and short, presenting a particularly ugly face. In severe cases, he will lose his ability to work and cannot take care of himself.

Zhong Jingjun said that the intellectual damage caused by iodine deficiency disorders is the first, and women and children are the main victims.

The iodine content varies with age. "We have to monitor the iodine content of residents' edible salt every year.

"Zhong Jingjun told the reporter that according to the current monitoring scheme, children in the development stage belong to iodine-sensitive population, but from the monitoring situation, the iodine intake level of the population in our county is appropriate, but this does not mean that we no longer need to supplement iodine.

"People need different amounts of iodine in different physiological periods.

"Zhong Jingjun said, generally speaking, the daily iodine intake of children under 4 years old should be not less than 5 micrograms, that of children aged 4 to 11 years old should be not less than 9 micrograms, that of teenagers and adults over 14 years old should be not less than 15 micrograms, and that of pregnant women and lactating women should be not less than 2 micrograms.

Zhong Jingjun told the reporter that every 5g of iodized salt (the amount of beer bottle caps) contains 15 micrograms of iodine, so we must adhere to the scientific principle.

"First of all, not everyone has to take iodine supplements.

"Zhong Jingjun pointed out that some patients with thyroid diseases, especially hyperthyroidism, should not take iodine supplements. These patients should eat non-iodized salt and foods with high iodine content such as kelp.

Secondly, the more iodine, the better, as the saying goes.

Too much iodine will make the symptoms of patients with hyperthyroidism difficult to control, and may also induce other thyroid diseases, which is harmful to health.

iodine is just the daily iodine intake of an adult. Scientific Prevention and Treatment of Iodine Deficiency Disorder Composition

Scientific Prevention and Treatment of Iodine Deficiency Disorder Iodine is a trace element in the human body, and its function is not small. If iodine is lacking in the human body, it will cause "iodine deficiency disorder".

Everyone must have eaten iodized salt, so how did the name come from? Let me introduce it: iodine is very important to the human body. If iodine is lacking, people will get sick.

iodine is a purple chemical element.

Iodine liquor and iodophor in our life are all made of iodine.

so where does iodine come from? Iodine comes from the sea. In the sun, iodine is evaporated and then falls to the earth and the ocean with rain and snow.

most animals and people get iodine from food.

After the loan enters the human body, it returns to the ocean with the excretion of urine.

If the place where we live is short of iodine, people's nutrition will not keep up and they will suffer from iodine deficiency.

When people are short of iodine, the amount of thyroxine synthesized will decrease.

Because the thyroid gland is the "hero" of many organs, once iodine is lacking, the organs will report the news to the commander's brain.

The brain immediately ordered the thyroid gland to produce in large quantities.

However, if the most important iodine is not increased, enough thyroid hormone can't be synthesized, so it can only cause goiter, which leads to the phenomenon of "big neck".

my god! If iodine is lacking, what a great harm it will do! However, what is more serious is that iodine deficiency will damage people's brain development and cause mental retardation.

If pregnant women lack iodine, their children will be disabled and their brains will be stunted.

If those children were not treated three months ago, people would have heard the cries of lovely children! Such children need others for everything, and how many parents feel distressed for them and shed tears for them! In order to prevent iodine deficiency, smart people in China made iodized salt in 1995, so that people can supplement iodine when they eat salt.

From now on, we will see more people smiling instead of crying! In order to prevent iodine deficiency disorders, let's work together! Prevention of iodine deficiency excellent composition urgent! ! ! ! ! ! ! ! ! ! ! !

How to prevent iodine deficiency disease iodine deficiency disease is caused by iodine deficiency, so its prevention and treatment should be to supplement iodine to the people in the ward.

The main measures to supplement iodine are: (1) Iodized salt: it is suitable for the whole people to supplement iodine for a long time. It is characterized by low price, easy access, convenient use, safety and reliability, easy popularization and long-term persistence, and it is a very effective method.

Iodized salt is the most important and fundamental means to prevent and treat iodine deficiency disorders in the whole world and China.

, (2) Iodine oil: divided into injection and oral administration.

Injection is an injection, usually intramuscular injection. The adult dose is 1 ml each time (containing 475 mg of iodine). Generally, one injection is given once, and the validity period is 2-3 years, and then repeated injections can be made.

The other is iodized oil pills, that is, oral iodized oil capsules (or capsules), the dosage of which is 1.4 times of the injection dosage, that is, adults take 665 mg once, and the validity period is about one year.

iodized oil should not be used as a long-term iodine supplement measure, but only as an auxiliary measure to promote iodized salt to ensure the normal intellectual development and physical development of fetuses and children.

Generally speaking, injection of iodized oil is more reliable than oral iodized oil pills, but people are more willing to accept oral method.

(3) Iodized water: Water is a necessity in daily life, and it is an ideal way to supplement iodine besides salt. The obvious defect of water is that it is widely distributed and it is not easy to concentrate on iodization.

However, in some special circumstances, iodized water is also an effective measure to correct iodine deficiency.

the methods of adding iodine to water are as follows: ① adding high concentration of potassium iodide or potassium iodate to drinking water drops in the container.

② Put an iodine-containing resin tube or iodine brick (collectively referred to as iodine slow-release device) into the well water, and let the potassium iodide in the tube slowly penetrate into the water through a proper device. This device can be used for one year.

③ using iodine to purify water: using 5 mg/l iodine to disinfect water can not only eliminate bacterial pollution, but also correct various iodine deficiencies, killing two birds with one stone.

Even excessive intake of iodine does no harm to human body.

Of course, the disadvantage of this method is that the iodine used must be pure iodine, and potassium iodide or potassium iodate is ineffective.
