Essay on iodized salt and health 300 words

We should eat less salt, salt is not good for the body.

Hello everyone, do you know the dangers of table salt? If you don't know, you will definitely say, "What you said is not right, if it is right, why do many people in the countryside say that as long as we eat more salt, our strength will increase, so we must eat more salt, because only in this way can we become stronger."

Yes? Many rural people say, "As long as we eat more salt, our strength will increase, so we need to eat more salt, because only in this way can we become stronger."

Now, let me tell you about the dangers of salt!

Seven things to open the door: "firewood, rice, oil, salt, sauce, vinegar and tea", indicating that salt is a necessity for people. The great writer of the Song Dynasty, Su Shi's poem, has "How can you forget the taste of Shao, and you will eat without salt in March".

If you don't put a little salt in the food when eating, even the delicacies of the mountains and seas are like chewing wax. Salt is not only an important condiment, but also an indispensable substance for maintaining the normal development of the human body. It regulates the balanced distribution of water in the human body, maintains osmotic pressure inside and outside cells, participates in the formation of gastric acid, promotes the secretion of digestive juices, and can increase appetite; At the same time, it also ensures the pH necessary for pepsin, maintains the balance of pH in the body, and the normal circulation of body fluids.

If you don't eat salt, you can't eat too little salt, and eating too little salt will also cause the sodium content in the body to be too low, and the phenomenon of loss of appetite, weakness of limbs, dizziness and so on; In severe cases, symptoms such as anorexia, nausea, vomiting, rapid heart rate, weak pulse, muscle spasms, blurred vision, and decreased reflexes may also occur. In ancient times, the Netherlands, Sweden and other countries stipulated that those who violated the criminal law were not allowed to eat salt for a period of time as punishment.

However, eating more salt is also harmful to the human body. The results of the scientists' research show that salt can "hydrate" the human body, that is, salt has a certain adsorption force on water, and the more salt in the human body, the water requirement will also increase accordingly, so that too much water is retained in the body, thus causing high blood pressure.

Someone has investigated the eating habits of residents in the northern area of Tokyo, Japan, who eat an average of 25 grams of salt per day, and those who suffer from high blood pressure account for 30 to 40% of all residents; In other parts of the world, only 5 15 grams of salt are eaten per day, and only 8 10% suffer from high blood pressure; Eskimos living in the Arctic Circle, who eat less than 5 grams of salt a day, almost never suffer from high blood pressure. Therefore, experts recommend that adults should not eat more than 12 grams of salt per day.

So if you eat too much salt, you will get sick.

Therefore, I would like to appeal: "We should all eat less salt, of course, not more salt, only a day no more than 6 kg of the body will be healthy, so for the sake of our health, let's eat salt properly!"

Salt and health.

Introduction: There are many benefits of iodized salt, come and see the "personality" resume of iodized salt! Hazards:

Iodine deficiency disease is an endemic disease that seriously endangers human physical and mental health, and iodine deficiency can cause menstrual abnormalities, infertility, miscarriage, stillbirth and other consequences. It can also cause endemic thyroid adenomas. More seriously, it affects brain development and leads to intellectual impairment.

Therefore, eating iodized salt is very important for everyone.

Benefits: There are two critical periods of brain development: the fetal period and before the age of three, and iodine deficiency during these periods can cause intellectual impairment and is impossible to recover.

Therefore, during the critical period of brain development, if people in iodine-deficient areas do not eat iodized salt, so that the body does not get enough iodine, brain development will be hindered. Therefore, it is more important for pregnant women to consume iodized salt before pregnancy and for infants and young children to consume iodized salt. Because iodized salt can help us grow healthily, we should eat more iodized salt.

Status: Environmental iodine deficiency has caused intellectual injury and a series of health problems in many countries and regions in the world, and more than 100 million people in China are affected by iodine deficiency. In 1995, the national iodized salt coverage rate was only 54%, which was lower than the international standard, but by 1999 this proportion had risen to 93%, and by 2005 the province had reached the stage goal of basically eliminating iodine deficiency diseases.

Iodine supplementation: Infants, young children, and women who are mothers or breastfeeding their babies should be sure to eat more iodized salt.

Rescue method: Eating qualified iodized salt is the best way to prevent iodine deficiency, and at the same time, students should eat more iodine-containing marine foods such as kelp, sea stingers, sea crabs, shrimps, sea cucumbers, and hairtail fish.

How to use: 1) Avoid rinsing iodized salt with water.

2) Avoid high temperatures. When stir-frying vegetables and making soup, put iodized salt in the pot, and never use iodized salt to stir-fry the pot.

3) Avoid adding vinegar or sour dishes, iodine is easy to destroy and decompose when it encounters acid.

4) Avoid stir-frying vegetables with animal oil, which is easy to chemically change with iodine to make it volatilized.

Students, after reading the "personality" resume of iodized salt, do you want to supplement iodine immediately and have a healthy body immediately?

The story of iodine.

I loved listening to my grandmother's stories, and she often told me all sorts of funny stories after dinner or before going to bed.

Once she told me about a patient in her village when she was a child: when my grandmother was young, she lived in a village in Chang'an County, and there was a person in the village who had a disease, and that person's neck was suddenly swollen, getting bigger and bigger, falling downward, falling longer and longer, and the facial muscles were taken downward, and finally there was a large piece of flesh hanging on his chest, and even one of the patient's eyes was stretched, and his whole face was distorted and deformed, beyond recognition. Although he couldn't see his own appearance, he had low self-esteem, and the neighbors looked at him, and it was so ugly and terrible, and he was often discriminated against because of this, and no one paid attention to him, and no one was friends with him.

After listening to my grandmother's story, I was so frightened that I asked my grandmother, "What disease did he have and why did he get this strange disease?" Grandma said, "This strange disease is called thick neck disease, which is caused by a lack of iodine in the body. ”

So what is iodine? Grandma said: "Iodine is an indispensable nutrient for the human body, when the body lacks iodine, there will be many problems, the most common is goiter, that is, thick neck disease, iodine deficiency can also cause deafness, dumbness, paralysis, the most important harm is that iodine deficiency affects the brain development of the fetus, resulting in children's intellectual and physical development disorders.

If you don't get injections and don't take medicine, can you prevent this disease? Grandma said, "Of course, we can prevent it from our diet and eat more iodine-rich foods, such as kelp, marine fish and other seafood."

Wow! I don't like kelp very much, but it seems that I will learn to love it and eat it more in the future. What else can be done?

Yes, we require the common people to consume iodized salt is the best way to prevent iodine deficiency diseases. "How do you use iodized salt?" "Use the same method as ordinary salt, avoid high temperatures.

When stir-frying and making soup, put iodized salt out of the pot, and never use iodized salt to burst the pot. Avoid adding vinegar or sour dishes, iodine is easy to destroy and decompose when it encounters acid. "Let's use iodized salt as soon as possible."

Grandma said with a smile

Silly grandson, we have always eaten iodized salt. "I'm relieved. ”

In order for us not to get sick of iodine deficiency and for the sake of our health, let's eat more kelp and eat iodized salt.

Solid foods such as biscuits, cereals and bread are often high in table salt, and feeding young babies with these foods can lead to a preference for savory foods throughout their lives. The study**, published in the American Journal of Clinical Nutrition, suggests that people should strive to reduce their salt intake early in life. According to the authors, it is possible that the situation will be like this:

In infancy and early childhood, there is a "sensitive window" in which certain foods and tastes are programmed into the brain, and these foods and tastes are craved in the future.

Leslie Stan says that although babies are born with a clear preference for sweet foods and an extreme aversion to bitter foods, they don't seem to mind saltiness in the first few months of their lives. When a two-month-old baby is fed saline, they don't show any facial expressions, which could mean that the baby isn't drinking the salty taste or that they don't care about the salty taste.

To get to the bottom of this question, Stan and his colleagues tracked 61 healthy two-month-old babies. If the children have already started eating, almost half (26) have eaten biscuits, soft bread or cereals, which are usually high in salt. In the drinking bottle water test, the babies drank 55% more salt water than those who had not been exposed to such foods.

When the 26 children reached preschool age, they rediscovered their preference for salty tastes and found that those who ate salt-rich starchy foods earlier preferred salty tastes.

Eating early in life alters the way salty signals are transmitted to the brain, and at that time in life, the brain is very malleable. These results suggest a correlation between early salty eating and later salty cravings. If this is true, then there are ways for parents to reduce the risk of craving salty food.

Iodized salt is effective in preventing iodine deficiency disorders. We need to consume iodized salt scientifically to improve the utilization rate of iodine.

First of all, the consumption of iodized salt is expensive to insist. Iodine supplementation in the human body is a long-term, daily and daily process, and normal people should consume iodized salt frequently, preferably every day.

Secondly, iodized salt storage methods should be appropriate. Iodized salt should be stored in glass or ceramic jars, covered and sealed in a cool place at low temperature. At the same time, iodized salt should not be stored for a long time, and it is advisable to buy it with food.

In the past, iodized salt was made by mixing potassium iodide into table salt, but because potassium iodide is easily oxidized in the air, it will cause iodine loss, and it is more expensive, so China has stipulated that potassium iodide is not added to salt since 1989, and potassium iodate is added instead (kio 3). Potassium iodate is a strong oxidizing agent, which will not be oxidized in the air or in contact with light; Moreover, potassium iodate is an ionic crystal with a high boiling point and is not volatile, so there is no need to emphasize adding salt before cooking or when eating. Some popular science articles emphasize that iodized salt should be kept away from light, and cooking iodized salt should not be done sooner or later, etc., which actually refers to potassium iodide, and there are no such conditions for potassium iodate.

Although iodized salt will not be oxidized in the air, in order to prevent it from being reduced, it is better to keep it sealed.

The iodine intake of the Chinese population is high.

The World Health Organization recommends a daily salt intake of 6 grams per person, but Chinese nationals generally exceed 20 grams. This requires the provision of non-iodized salt as a choice, otherwise the risk of excessive iodine intake is extremely high.
