I like listening to grandma's stories very much. She often tells me all kinds of interesting stories after dinner or before going to bed.

Once she told me the story of a patient in her village when she was a child: my grandmother lived in a village in Chang 'an County when she was a child. There is a man in the village who has a disease. The man's neck suddenly swelled up, getting bigger and bigger, falling down and getting longer and longer, and his facial muscles were taken off. The last big piece of meat hung on her chest, and even the patient's eye was stretched. Although he can't see himself, he feels inferior, and his neighbors look at him, which is really ugly and terrible. Because of this, he is often discriminated against, no one cares about him and makes friends with him.

After listening to grandma's story, I was surprised and scared. I asked my grandmother, "What happened to him? Why did he get this strange disease? " Grandma said: "This strange disease is called thick neck disease, which is caused by iodine deficiency in the body."

"So what is iodine?" Grandma said: "iodine is an indispensable nutrient for the human body." When the body is short of iodine, there will be many problems. The most common is goiter, which is coarse neck disease. Iodine deficiency can also lead to deafness, deafness and paralysis. The main hazard is that iodine deficiency affects the development of fetal brain, leading to mental and physical development disorders in children. " "Can you prevent this disease without injections and medicine?" Grandma said: "Of course, it can be prevented from diet and eat more foods containing iodine, such as kelp, sea fish and other seafood." "wow! Kelp, I don't like it very much. It seems that we should learn to love and eat more in the future. What else can we do? " "Yes, we ask people to eat iodized salt, which is the best way to prevent and treat iodine deficiency disorders." "How to use iodized salt?" "The method used is the same as ordinary salt, and high temperature should be avoided. Stir-fry and cook soup with iodized salt, and never use iodized salt to cook the pot violently. Avoid adding vinegar or sauerkraut, iodine is easy to decompose when it meets acid. " "Hurry up and use iodized salt." Grandma smiled and said:

"Silly grandson, we have been eating iodized salt." "I am relieved."

For iodine deficiency and our health, let's eat more kelp and iodized salt.

In the family of trace elements, there is a component about iodine that has to be mentioned. It is a trace element that our human body needs very much. Without it, people's brain development will be affected, their intelligence will be damaged, and their physical development will be hindered. Yes, it is iodine. Iodine is one of the essential trace elements for human body and is called "intellectual element". The total amount of iodine in healthy adults is 30 mg (20 ~ 50 mg). 70%~80% of them are in the thyroid gland. Iodine can promote the biological oxidation in the tricarboxylic acid cycle, thus obtaining energy from it and transmitting it to the body. It can be said that iodine is an indispensable "porter" in human body. Iodine also has the function of maintaining body balance and promoting bone development. Therefore, the human body cannot be short of iodine. Iodine occupies an extremely important position in our body. If we lack it, many kinds of iodine deficiency disorders will follow. Iodine deficiency can cause goiter, which is called "big neck disease". This disease will make the neck thicker and bigger, making people feel difficult to breathe. In addition to goiter, iodine deficiency will slow down or even stop our bone development, and our intelligence will also be affected. Iodine deficiency can also make people deaf, dumb and paralyzed, which will bring inconvenience to our later life. Iodine deficiency. If you don't want it to have anything to do with yourself, you should supplement iodine scientifically. In fact, it is not difficult to supplement iodine scientifically. As long as you take proper iodine-containing health care drugs regularly and eat more iodine-containing foods in your daily life, you can effectively prevent iodine deficiency. In life, the most common iodine-containing food is iodized salt. 25%~30% of iodized salt contains iodine. Although the proportion of iodine is very small, it can achieve the purpose of supplementing iodine. Buying iodized salt is. In order to avoid eating some unhealthy things by mistake, kelp, laver, Chinese cabbage, marine fish, shrimp, crab and shellfish are also rich in iodine, so you can eat more. In life, it is not difficult to prevent iodine deficiency as long as we pay more attention to small iodine and supplement iodine. Pay attention to iodine and our health. ....

The composition of 300 to 400 words about iodine is urgent! China is a country with serious iodine deficiency, and iodine deficiency areas are widely distributed, almost involving 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, with inconvenient transportation and backward economy and culture.

Moreover, iodine supplementation must be persisted for a long time, year after year, generation after generation, otherwise people living in iodine-deficient areas will suffer from iodine deficiency disorders 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 way to prevent iodine deficiency disorders by eating iodized salt. Historical data prove that this method has been used for 100 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 Prevention and Control of Iodine Deficiency Disorders have strongly supported the prevention and control of iodine deficiency disorders, and advocated edible iodized salt as the basic method for the prevention and control of iodine deficiency disorders.

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

Such as the United States, France, Canada, Japan and so on. Due to high cultural quality, people have a deep understanding of the harm of iodine deficiency and a strong sense of self-care.

Although these countries sell iodized salt and non-iodized salt at the same time, 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.

The most fundamental measure to prevent iodine deficiency is iodized salt.

This is confirmed 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.

However, 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, the following matters should be paid attention to in use to ensure the maximum efficacy of iodized salt.

1, pay attention to the preservation method of iodized salt.

It is necessary to put iodized salt in a glass or ceramic jar with a cover, and put the jar in a cool place, out of direct sunlight, and try not to heat the salt.

Iodized salt is stored at high temperature, and the loss of iodine is faster than that at low room temperature.

Therefore, the preservation method of 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 eat iodine.

2. Pay attention to cooking methods.

When cooking, we are used to adding salt first, and iodine will evaporate when heated.

So try to add salt after cooking, and don't fry vegetables with hot oil and iodized salt.

Pay attention to the amount of salt you eat.

According to the standard of iodized salt in China, each person can get about 120 micrograms of iodine by eating 6 grams of salt every day, which can completely meet the physiological needs of most adults.

Pregnant or lactating women, infants and other people with special needs need more iodine than the average person.

Therefore, it is suggested that pregnant women, lactating women, infants and other people with special needs 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 amount of iodine.

More than 300 words about iodine deficiency iodine is a quantitative element and an indispensable substance for human body.

If there is too much iodine, it is harmful to human body; But too little iodine is harmful to human body, in other words: iodine must be moderate, neither too much nor too little.

In the sea, this naughty little iodine is hidden here.

Water was evaporated, iodine also came to the atmosphere with water vapor, and iodine came to the earth again with ice, snow and rain.

It rains all the time in some places, so there is a lot of iodine, and people there are in good health; In some places, the iodine content is relatively low, causing many diseases.

However, these diseases have vanished now. With the development of science and technology, we have ways to deal with these diseases. We mix iodine with salt, because everyone needs to eat more salt every day, so everyone can eat more iodine every day. Why don't we be smarter! Iodine is good for human body, but it must be moderate.

On Friday, Mr. Chen showed us a video about iodine deficiency.

Iodine is an indispensable rare element for human body.

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

Lack of iodine in pregnant women is likely to lead to miscarriage.

Even if children are born, they are not healthy, and most of them may even be mentally retarded.

Looking at the faces with some dementia, I looked at the front with empty eyes numb, and there was no mood fluctuation in my eyes.

I can't help feeling a little sad. God gave them bodies in life, but not souls.

Without self-care, they are like cold machines, walking dead.

Living means nothing to them.

Have ears but can't understand anything; Have eyes but can't understand anything; A mouth can't explain anything; Have brains but don't know what to think; Have a life but 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 were not distributed to areas with high iodine content, saving the lives of countless children.

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

Every pair of eyes is bright, intelligent, emotional and dreamy.

The limbs are also healthy, with clear consciousness and clear thinking.

Perhaps some people will only sympathize with those who are not sound, in fact, we are more worthy of sympathy, because the brain is not used all the year round, which leads to rust.

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 iodine I know wrote 300 words, but he felt inferior. He will have many problems when he is short of iodine. The most common is goiter. Eat more kelp: "What's wrong with him? Why did he get this strange disease? " Grandma said, I was shocked. She lives in a village in Chang 'an County. There is a man in the village who has a disease. The man's neck suddenly swelled up. Neighbors looked at him like kelp. We always eat iodized salt. Really ugly. We ask people to eat iodized salt, which is the best way to prevent and treat iodine deficiency disorders.

""How to use iodized salt? " "The method used is the same as ordinary salt, sea fish and other seafood! Kelp, paralysis, the main harm is that iodine deficiency affects the development of fetal brain, leading to mental and physical development disorders of children.

""can you prevent this disease without an injection or medicine? Grandma said, "Of course, we can take precautions from our diet and eat more foods containing iodine. It seems that we should learn to love and eat more in the future. "

What else can we do? ""yes.

"I'm relieved.

"In order to prevent iodine deficiency, facial muscles were removed and finally turned into a large piece of meat hanging on the chest.

Add iodized salt when cooking and making soup. No one is friends with him, and iodine decomposes easily when it meets acid.

""use iodized salt quickly.

"Grandma said with a smile.

After listening to grandma's story: "stupid grandson, for our health, he is dumb and afraid of avoiding the high temperature." It's terrible to ask grandma that her whole face is twisted beyond recognition. Because of this, she is often discriminated against and nobody cares about him. Even if one eye of that patient is slender, iodine deficiency can cause deafness. "

"wow.

Avoid adding vinegar or sauerkraut, don't like it very much, and don't cook violently with iodized salt. Grandma said: "iodine is an indispensable nutrient for the human body."

Once she told me a story about a patient in the village when she was a child: My grandmother was called coarse neck disease when she was a child: "This strange disease is called coarse neck disease, which is caused by iodine deficiency in the body.

""So what is iodine? Bigger and bigger, falling and falling longer and longer.

Although he can't see himself, I love listening to grandma tell stories. She often tells me all kinds of interesting stories after dinner or before going to bed. ...

The composition about iodine deficiency is 800 words 1, and the mental retardation caused by iodine deficiency cannot be cured. Intellectual deficiency caused by iodine deficiency, like other intellectual deficiencies, is a manifestation of brain dysfunction, and it is difficult to reach the normal level.

Mild mental retardation, if it can be found early and received special education, can make him reach the level of primary school graduation.

Only after strict training can these patients improve their adaptability to life, master some simple labor skills and become "self-reliant workers".

Long-term practical experience shows that it is impossible to restore the intellectual execution of iodine deficiency patients to normal level through treatment.

Therefore, active prevention of iodine deficiency disorders is of great significance to the national economy and people's livelihood.

2. Iodine deficiency is the most common cause of mental retardation. Some diseases, such as hereditary diseases, congenital metabolic abnormalities, consanguineous marriage, brain damage caused by labor injury and acquired diseases, iodine deficiency, etc., can lead to mental disability.

Iodine deficiency is the most common cause.

Among the 1.0 1.7 million children with mental disabilities in China, 80% are due to iodine deficiency.

Every year, 20 million newborns are born in China, of which 6 million are in iodine-deficient areas. According to the average IQ loss of 6.5438+0.35 million percentage points caused by iodine deficiency, if iodine deficiency is not prevented, more than 80 million potential quotients will be lost every year, which shows the serious impact on population quality.

3. The harm of iodine deficiency to infants and young children are in the second critical period of brain development.

Like the fetus, it is extremely sensitive to iodine deficiency.

If the fetus is severely iodine deficient until infancy, it is bound to develop into a typical cretinism patient.

If children's iodine deficiency is mild, there may be mild cretinism syndrome spectrum, and their intelligence and growth and development are backward.

There is less goiter.

Infants and fetuses are one of the target groups to evaluate the prevalence of iodine deficiency disorders.

4. Brain development is inseparable from iodine. It is generally believed that a high intelligence means a good brain.

If the brain develops normally and healthily, it will be easy to use, and people will appear smart and have high intelligence; If the brain is underdeveloped or defective, it will damage the intellectual ability, leading to mental retardation and even disability. Of course, the brain is not easy to use.

Scientific research has found that the human brain has two vigorous stages of development and differentiation during fetal development, namely the most vulnerable stage, also known as the "fragile stage". First, at the gestational age 10- 18 weeks, embryonic nerve cells proliferate, develop, differentiate and migrate to form a brain; Second, more than 3 months before death to 2 years after birth, which is the main stage of brain development.

The development of the brain needs the promotion of thyroxine, otherwise the slow or incomplete development of the brain will affect the development of intelligence.

The metabolism of pregnant women is strengthened, which increases the demand for thyroxine, coupled with the demand of the fetus, which further increases the demand for iodine raw materials for synthesizing thyroxine.

If there is iodine deficiency in the environment at this time and it cannot be replenished in time, it is easy to cause iodine deficiency in fetuses and fetuses during pregnancy.

This is even worse for the fetus, because at this time, the fetus is at a disadvantage in the process of mother and child competing for iodine.

This will inevitably lead to low or insufficient fetal thyroid function, which will damage the development and proportion of the nervous system and brain, cause brain hypoplasia or defects, seriously affect intellectual development, and lead to mental retardation, mental retardation or intellectual disability.

Basic knowledge of prevention and treatment of iodine deficiency disorders In order to better popularize the scientific knowledge of prevention and treatment of iodine deficiency disorders, mobilize the whole society to participate in the prevention and treatment of iodine deficiency disorders, and realize the goal of completely eliminating iodine deficiency disorders in our county, our bureau specially published the Wall Newspaper of Basic Knowledge of Prevention and Treatment of Iodine Deficiency Disorders.

1, iodine deficiency disorder (IDD) is a group of diseases caused by iodine deficiency in natural environment.

It includes endemic goiter, cretinism and sub-cretinism, simple deafness, fetal abortion, premature birth, stillbirth and congenital malformation.

2. The most economical, simple, effective and safe way to prevent iodine deficiency disorders is to eat iodized salt for a long time and stick to it for generations.

3. Preservation method of iodized salt The purchased iodized salt should be properly preserved: (1) The container for containing iodized salt should be a brown light-shielding bottle or a ceramic jar with a lid.

(2) Iodized salt should be stored in a cool and dry place away from fire sources, avoiding humidity, sunlight and high temperature.

(3) The storage time of iodized salt should not be too long, and it should be bought as you use it and properly preserved.

4. Know when to put iodized salt when cooking. To prevent iodine loss, it should be noted that: (1) Do not wash with water when cooking.

(2) When cooking soup, it is not advisable to put salt too early, and put it when the soup and vegetables are almost cooked, so as to avoid iodine volatilization when heated.

(3) Don't fry iodized salt in a pan, let alone use an oil pan.

5. People with special needs for iodine The so-called people with special needs for iodine refers to people who are in a special physiological stage and have different needs for iodine from normal people, including newborns, infants, preschool children, pregnant women and lactating women.

6. Pregnant women should supplement iodine in time, because iodine deficiency in pregnant women will not only cause premature delivery, abortion and congenital malformation, but also affect the normal development of fetal brain. Therefore, women of childbearing age and pregnant women should supplement enough iodine, and women should supplement more iodine because of breastfeeding needs.

7. When is the publicity day for preventing iodine deficiency disorders? Which IDD Prevention Day is this year? What is the propaganda theme? What is the slogan? May 15 is the publicity day for prevention and treatment of iodine deficiency disorders every year.

8. The greatest harm of iodine deficiency in human body.

Iodine, an essential element for human body, what would we do without iodine? Let's talk about the role of iodine, 1. It is responsible for substance metabolism, maintaining a constant body temperature, 2. It is responsible for physical development. Affect the normal development of the brain.

You may say, since iodine is so important, where can we get it? In fact, we are supplementing iodine every day. The seafood you eat, iodized salt, all contain iodine.

Especially kelp, the iodine content is particularly rich.

The inexhaustible iodine in our body is excreted with urine.

Therefore, no matter how much iodine you eat, it will be excreted.

In addition, if you eat too much iodine, you will get thyroid! What is the harm of iodine deficiency? 1, goiter, commonly known as "big neck".

Just a thick neck.

2. Endemic cretinism, that is, stunting, often leads to mental retardation.

3. Fetal death. Iodine deficiency in pregnant women will lead to fetal death and premature withering of flower of life.

So how do we prevent it? The best way is to eat iodized salt, which is safe, effective and convenient.

However, it should be noted that if you want to buy something marked with iodized salt, don't buy that kind of private salt, which does not contain iodine.

Another way is to eat more foods rich in iodine, such as seafood, seaweed and kelp, which are all good iodine-containing foods.

Iodine, an indispensable ingredient, can help us build a better home if we take it in moderation! Give the respondent a gift and a kiss. Words: What a handsome answer! The landlord sent a kiss to express his sincere thanks!

Iodine exists in the form of iodide, which is soluble in water and can migrate with water, so the iodine in mountain water is lower than that in plain and coastal areas.

Iodine is an essential trace element for human body. The normal iodine content of adults is about 20~50mg, of which 20%(4~ 10mg) exists in thyroid.

Iodine is mainly supplied by food (about 80~90%), and the rest comes from water (10~20%) and air (5%).

At present, China's nutrition circles suggest that the iodine supply for infants aged 0-6 months is 40μ g/d, that for infants aged 6 months-1 year is 50μ g/d, that for children is 70- 120μ g/d and that for adults is150μ g/d.

For many years, people's understanding of the harm of iodine deficiency was limited to endemic goiter and endemic cretinism.

With a large number of in-depth experimental studies and epidemiological investigations, people gradually realized that iodine deficiency caused harm in different stages of human growth and development far beyond these two diseases, as well as a considerable number of diseases such as premature delivery, stillbirth, congenital malformation, subclinical cretinism, hypothyroidism of newborns, simple deafness and so on.

So there is such a concept: iodine deficiency-a series of obstacles caused by insufficient iodine intake at different growth and development stages, mainly including endemic goiter, endemic cretinism, subclinical cretinism, mental retardation and reproductive dysfunction.

Iodine deficiency syndrome (IDD) is an endemic disease with the largest number of patients in the world.

After long-term unremitting efforts in China, iodized salt has made outstanding achievements in the prevention and treatment of iodine deficiency disorders. The national iodized salt coverage rate reached 83%, and 19 provinces, municipalities and autonomous regions basically controlled endemic goiter and cretinism.

Iodization with salt is the first choice to prevent iodine deficiency disorders.

According to the salt intake per person per day 10g, the equivalent intake of iodine is 255~380μg, which is enough to maintain physiological needs.

Iodine deficiency composition primary school 600 words iodine is a trace element in the human body, and its role is not small. If the human body lacks iodine, it will get "iodine deficiency disease".

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

Iodine is a purple chemical element.

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

So where does iodine come from? Iodine comes from the ocean 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 disease".

When the human body is short of iodine, the synthetic thyroxine 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.

But if we don't increase the most important iodine, we can't synthesize enough thyroid hormone, so it will only cause goiter, which will cause the phenomenon of "big neck".

Oh, my God, what a harm it will be if iodine is lacking! But what is more serious is that iodine deficiency will damage people's brain development and cause mental retardation.

When pregnant women lack iodine, their children will be disabled and their brains will develop slowly.

If those children had not been treated three months ago, people would have heard the cries of lovely children! Such children need others for everything, and how many parents feel sorry for them and cry for them!

The composition assigned by the teacher today is a composition about "iodized salt". I don't quite understand. When I got home, I asked my grandmother, and she said that iodized salt is 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, also known as "big neck disease".

The biggest harm of iodine deficiency disorders is to make infants' brains backward, their intelligence low, and even stupid, dull and stupid; Iodine deficiency will hinder women's reproductive function and cause infertility, abortion, stillbirth and fetal malformation. Iodine deficiency will also reduce the work, learning ability and labor efficiency of adults and adolescents.

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

Most parts of our country are short of iodine, so we should insist on eating iodized salt all the year round.

Therefore, the state forces iodized salt, which is why most things we see in supermarkets are iodized salt.

Excessive iodine intake is also harmful to human health.

There are two types of people who cannot eat iodized salt. They are people in high iodine areas and people who are not suitable for iodized salt because of treating diseases (such as thyroid diseases).

China's "Regulations on the Administration of Iodized Salt to Eliminate the Harm of Iodine Deficiency Disorders" clearly stipulates that these two groups of people can buy non-iodized salt in shops specially set up by the salt industry department.

Please indicate the source? The iodine I know has written 300 words.
