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. Maybe 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.
2. Composition on Iodine 400 words 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.
I will give you a model essay for reference as soon as possible. I hope you can write your composition well, and I wish you a step-by-step promotion in your study! The role of iodine in a dense forest, there lived a group of cute little animals.
There are "all-knowing" panda doctors, clever waiters, clever bunny sisters, diligent and enterprising dogs and greedy and sleepy pigs. They are as United and friendly as a family.
One day, the pig's neck was swollen like water. All the animals came to see him.
Sister Bunny said anxiously, "Flower Magpie, go and invite Dr. Panda from our forest." Dr. Panda has arrived.
He looked at the pig and asked him about his usual diet. He said: "pigs have big neck disease, which is caused by iodine deficiency." "What is iodine?" The puppy asked incredulously.
"Iodine is an essential trace element for human body. If you lack iodine, you will suffer from iodine deficiency. " "Then how to prevent iodine deficiency" asked the little animal eagerly.
"There are many ways to supplement iodine. We can have a simple way, which is to eat iodized salt.
Piglets should eat more iodized salt, and all of you should eat more. "Dr Panda said earnestly.
"Thank you so much, Dr. Panda." The little animals said in unison.
A few months later, the pig recovered and the forest became beautiful again. (This content comes from the composition book. com。

5. How to write a dialogue about iodine in the composition (preface) "Hi! Hello, classmates! You may not know me. People call me intellectual element, but my real name is iodine, which is a nonmetallic element. My appearance is a deep purple crystal, which is very rare in nature and only exists in water-soluble form.
Although I am ugly, I am very useful! "A bottle with" iodine "written on the publicity platform of iodine deficiency disorders in school saw that the students were all around me, and" iodine "enthusiastically introduced itself." Black, really ugly, has a great effect? Bragging? "I looked at it like that, mumbling.
Looking at the expressions of disbelief on the students' faces, "iodine" explained in more detail. "Classmate, you know, when your mother is pregnant with you, if you lack me, you will have serious consequences such as brain dysplasia, deafness, paralysis, deformity and death.
When you were a baby, without me, your brain would develop slowly and react slowly to what you touched, and your sports ability, intelligence and growth could not reach the level of children of the same age. In childhood, if you still lack me, then your brain weight will not reach the average level, and there will be' neck roughness', which is not only mental retardation, short stature, slow movement, but also stupid and ugly face. "
"Wow, that's terrible." The students "wow" suddenly exploded. I immediately thought of the disabled students in Qizhi School and asked "iodine": "So, iodine deficiency will cause mental retardation, low IQ and become mentally retarded, right?" "By the way, you are smart, which proves that you have supplemented and absorbed me enough when I was growing up." "Iodine" said to me appreciatively.
I gasped, thinking: fortunately, when my mother had me, she supplemented all kinds of nutrition and iodine at the same time, which was attributed to a large pile of books on infant nutrition knowledge at home. Just thinking, "iodine" said seriously: "Students, you can be happy now. In order to eliminate iodine deficiency disorders, reduce mental retardation, improve IQ and protect the health of women and children, the state sets up a special "iodine deficiency disorders prevention day" every year to publicize the harm of iodine deficiency disorders and let people know more about me.
Students, although you are healthy and smart now, don't ignore me, because I am very important to your growth. So you must add my "iodine" salt to the salt you eat, and eat more kelp and seaweed at ordinary times, then I will be enough for you to grow. "
After listening to "iodine", the students seemed to have a vivid health care class and benefited a lot! In addition, the role of iodine has been fully understood.
6. Iodized salt as a proposition How to write a primary school composition I am an indispensable friend in people's lives-iodized salt.
Want to know how I was formed? To tell you the truth, adding potassium iodate to salt forms me- iodized salt. With me, people can easily inhale iodine ions.
Want to know how good I am? Let me explain it to you in detail. The living environment of human beings is short of iodine, which needs long-term moderate iodine supplementation, and human beings need to eat appropriate amount of salt every day, so eating my iodized salt has become the best way to supplement iodine. It can be said that I am a good assistant for human iodine supplementation! By the way, eating iodized salt is the most convenient, effective, economical, extensive and fundamental measure to prevent iodine deficiency disorders! How's it going? Is it awesome? Our five series of iodized salt have been recognized by experts.
Of course, don't forget that it is enough for everyone to eat 5- 10g iodized salt every day, which can supplement 100-200 micrograms of iodine, fully meeting people's demand for iodine!
I haven't told you the most important point. I am also an important raw material for human body to synthesize thyroxine. Iodine plays an important role in human growth and development, especially in intellectual development. No, my master just bought it for me from the supermarket the other day to supplement iodine for their children. Now, I am the master's favorite! I also became the best friend of the young master! If the mother who wants to have a baby in the future lacks iodine, the baby born may be deformed, stupid, deaf and even severely paralyzed! Do you think it's terrible? So, "moms" need me!
Let me be the closest friend in your life! Remember, don't forget to add some "iodized salt" when cooking.
7. I will give you a model essay for reference as soon as possible about iodine's composition of 300 words. I hope you can write your own composition well, and wish you a step-by-step promotion in your study! The role of iodine in a dense forest, there lived a group of lovely animals.
There are "all-knowing" panda doctors, clever waiters, clever bunny sisters, diligent and enterprising dogs and greedy and sleepy pigs. They are as United and friendly as a family.

8. Composition about iodine 400 words 1 What should the human body eat for iodine deficiency? The iodine content of marine life is very high.
The foods with the highest iodine content are seafood, such as kelp, laver, fresh hairtail, dried clams, scallops, mussels, sea cucumbers, jellyfish and lobsters. The iodine content in kelp is the highest, reaching more than 240 mg/kg in dried kelp; Followed by marine shellfish and fresh marine fish (about 800 μ g/kg). However, the iodine content in salt is very small. The more refined the salt, the less iodine it contains. The iodine content in sea salt is about 20 micrograms per kilogram. If each person ingests 10 g of salt every day, only 2 micrograms of iodine can be obtained, which is far from meeting the needs of preventing iodine deficiency disorders.
The iodine content of eggs and milk is the highest (40 μ g/kg ~90 μ g/kg), followed by meat. The iodine content of freshwater fish is lower than that of meat, and the iodine content of plants is the lowest, especially fruits and vegetables. 80%-90% of human iodine comes from food, 10%-20% from drinking water and 5% from air. Therefore, iodine in food is the main source of iodine in human body.
Iodide in food can only be absorbed if it is reduced to iodine ions, and iodine combined with amino acids can be directly absorbed. Calcium, fluorine and magnesium in the gastrointestinal tract will hinder the absorption of iodine, especially in the case of iodine deficiency.
When protein and calories are insufficient, it will hinder the absorption of iodine in gastrointestinal tract. Respiratory tract and skin can also absorb a small amount of iodine.
The physiological function of iodine in human body is realized by synthesizing thyroid hormone, which is one of the most important hormones in the body. Its main physiological functions are: (1) maintaining energy metabolism (decomposing substances to provide energy for life activities) and generating heat (maintaining body temperature). The reduction of thyroid hormone synthesis caused by iodine deficiency will lead to the impairment of basic life activities and physical decline, which is lifelong.
(2) promote physical development. Thyroid hormone regulates bone development, sexual development, muscle development and height and weight in children's growth and development.
Thyroid hormone deficiency can lead to symptoms and signs of physical development, sexual development, short stature and muscle weakness. (3) brain development.
At some stage of fetal or infant brain development, we must rely on thyroid hormone. Its deficiency will lead to different degrees of backwardness in brain development and different degrees of mental retardation after birth. This obstacle is basically irreversible, and it is useless to supplement iodine after the critical period, but iodine supplementation can also ensure the normal development of the body, correct hypothyroidism, restore physical fitness, and indirectly improve intellectual activities.
At noon today, my mother found that the salt at home was used up, so she asked me to run errands to buy salt. I said, "My treat!" Then rushed to the door.
After a while, I went to the nearest Weimin store to buy a pack of salt, but turned around and ran back without looking. When I got home, my mother looked at the salt, pinched my little nose angrily and humorously and said, "Qingqing, I bought the wrong one!" " "I asked curiously," isn't this salt? " My mother pulled me down and said with a smile, "We want to buy iodized salt. "
"Iodized salt." I was very surprised by this new term. My mother went on to say, "Iodine deficiency can lead to iodine deficiency (10 iodine deficiency), which is a disease caused by iodine deficiency in the natural environment where human beings live.
It not only includes endemic goiter and endemic cretinism, but also includes abortion, premature delivery, stillbirth, congenital malformation and increased neonatal mortality in iodine-deficient areas. More seriously, iodine will affect the brain development of embryos, infants and children, causing different degrees of intellectual damage. Iodine deficiency also has adverse effects on adults, resulting in poor intelligence and physical fitness.
Among iodine deficiency patients, endemic goiter and endemic cretinism are the most obvious and were first discovered. In a word, iodine deficiency will cause serious damage to human body at different stages of human development. "
You can also contribute. I interrupted my mother: "According to you, iodine deficiency disorders are as serious as SARS, as arrogant and as rampant in China?" "The facts are different. As long as iodine is supplemented for a long time, such diseases can be effectively prevented. Iodine supplementation is not a short-term behavior. Even if IDD disappears, once IDD occurs again, IDD will occur.
I think we should also consider living measures to supplement iodine. We humans had better supplement iodine unconsciously every day. Salt is the best way to supplement iodine.
People can't live without salt, so iodizing salt to prevent iodine deficiency disorders is the most common, active and beneficial intervention measure adopted by all countries in the world. I suddenly realized, "Teng" stood up, picked up the salt bag and rushed out of the house.
What should I do? That is to change iodized salt.
9. About the composition of iodine 700 words iodine, I am no stranger to the strange name iodine.
"Big neck", an image that only appears in the fairy tale world. Everything is so strange and so far away.
However, one day, the appearance of a person completely broke my sleeping dream, and in an instant, my vision became clear. It was a noon last autumn. I leaned against the threshold and looked out, hoping to find some good friends to have a good time.
Suddenly, a figure came into my sight. He's so strange-it's not cold, but he's already wearing a trench coat with a high collar over his ears. A big scarf surrounds the whole neck.
What's wrong with that? He is ill, but he walks very hard. He is a thief, and he doesn't look like you ... I didn't think much. He turned into the hospital opposite my house. Curiosity drove me to rush over ... The stranger finally walked into Zhang Zhiyuan's office.
That's great. Uncle Dean usually amuses me the most. I have to find an excuse to go in and have a look. "Uncle, I have some water!" I pushed open the door of Zhang Zhiyuan's office.
"Ah ..." The person in front of me startled me. How is that possible? This weirdo has taken off his scarf at this time, revealing a strange neck. The neck is thicker than the average person, and something like pomegranate hangs obliquely below the right ear.
What is this? Is he in pain? Many problems bother me. With that weirdo gone, I can't wait to pour out my doubts to Zhang Zhiyuan.
Zhang Zhiyuan sighed deeply and said to me, "What pomegranate is this? He has a' big neck' disease, which is caused by iodine deficiency. " "iodine deficiency?" I looked at him doubtfully.
"Yes, lack of iodine. Iodine is an indispensable element for human body.
Iodine deficiency will not only affect people's intellectual development, but also directly affect people's endocrine system and immune system. "Big neck" disease is just one of the diseases caused by iodine deficiency. "
"Iodine, how important it is to us!" I can't help thinking, "but how can we prevent it?" Zhang Zhiyuan took a sip of water and then said, "It's actually very simple to prevent iodine deficiency. Just eat more foods rich in iodine. The best and affordable way is to eat iodized salt. " "Eating iodized salt is easy!" I seem to have discovered a new continent.
"Eat iodized salt, knowledge can be great? First of all, it is necessary to distinguish which salt contains iodine, and then seal it. Be sure to put it in the pot when cooking! Go home and read more information, and you will learn more ... "Alas! Uncle Dean started teasing me again, and I quickly left the scene. Eat iodized salt and cherish your health.
Iodine, I am no stranger.
10. In the family of trace elements, there is an indispensable component about iodine. 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), of which 70%~80% exists in the thyroid gland. Iodine can promote the biological oxidation in the tricarboxylic acid cycle, thus obtaining energy from it and then transmitting it to the body. It can be said that iodine is an indispensable "porter" for human body. Iodine can also keep the body balanced.
Iodine occupies an extremely important position in our body. If we lack it, many kinds of iodine deficiency will follow. Iodine deficiency can cause goiter, which is what we call "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 the growth of our bones, and our intelligence will also be affected. Iodine deficiency can also be very serious.
Iodine deficiency is terrible. If you don't want to get involved 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, but it can supplement iodine. It is forbidden to buy iodized salt in regular retail stores to avoid eating unhealthy things by mistake.
In life, it is not difficult at all as long as we pay more attention to small iodine, supplement iodine and prevent iodine deficiency. Pay attention to iodine and our health.
