Method: Pour cumin and salt into the pot, wrap it in a cloth after frying, iron the sore spot, and change it several times after it cools.

Efficacy: dampness and wind, cold and pain relief, rheumatic joint pain.

1. Buy less and eat in time.

Buy in small quantities and buy again after eating, the purpose is to prevent the sublimation of iodine. Because potassium iodate will decompose and volatilize under heat, light, wind and humidity conditions.

2. Avoid high temperatures.

When stir-frying vegetables and making soup, avoid putting iodized salt at high temperatures. When stir-frying and stir-frying, iodized salt is put in the pot, the consumption rate of iodine is only 10%, and the consumption rate of iodized salt in the middle is 60%; When out of the pot, the consumption rate of iodized salt is 90%; The consumption rate of iodized salt can reach 100% when cold dishes.

3. Do not store it in the container open for a long time.

If iodized salt is in contact with sunlight and air for a long time, iodine is easy to volatilize. It is best to put it in a colored glass bottle, and after use, the cap is tightly closed and stored.

Fourth, avoid adding vinegar.

Iodine is destroyed when it binds to acids. According to tests, if vinegar is added at the same time when stir-frying, the consumption rate of iodine will be reduced by 40% to 60%. In addition, when iodized salt encounters sour vegetables (such as sauerkraut), the consumption rate will also decrease.

5. Salt and radiation.

In March 2011, there were two main reasons for the panic purchase of salt in supermarkets in many places in China. First, all the salt in our country is iodized salt, and the iodine in it is potassium iodide, the main ingredient of iodine tablets. Many members of the public may feel that eating more salt can protect them from radiation at critical moments.

On the other hand, residents of some coastal cities in Guangdong are worried that the seawater will be contaminated by Japan's nuclear radiation and will not be usable, and that if the salt stock is insufficient, it will cause the price to rise.

Regarding the first concern, an expert from the Guangdong Provincial Center for Disease Control said that the iodine content in table salt is very low, and even if people eat a lot of salt, it will not have much effect on radiation protection. Excessive consumption of iodized salt is harmful to the human body, this is what the head of the health department said.

Salt is an indispensable food for the human body, and the chlorine, sodium and other components it contains play a great role in maintaining the normal function of human nerves, muscles and heart.

The latest edition of the Dietary Guidelines for Chinese Residents (2016) recommends that adults should not consume more than 6 grams of salt per day, and one spoonful of salt on the market is 2 grams, and each person is 3 spoons of salt per day. According to the calculation of putting a spoonful of salt in one dish, for a family of three, if you cook three dishes per meal a day, you can calculate and control the amount of salt used in each dish. Each person should eat a maximum of 1 3 per dish to ensure that the salt intake does not exceed the standard.

1Na and Cl are the main ions that maintain the osmotic pressure of extracellular fluid; K and HPO4 are the main ions that maintain the osmotic pressure of intracellular fluid. In the total cation of the extracellular fluid, Na accounts for more than 90, and Cl accounts for about 70 of the total anion. Therefore, table salt plays an important role in maintaining osmotic pressure, which affects the movement of water in the human body.

It also plays a role in maintaining the normal excitability of nerves and muscles.

2. On an empty stomach in the morning, drink 1 cup of light salt soup, which can not only clean up the stomach fire, remove bad breath and bitter and tasteless in the mouth, but also enhance digestive function, increase appetite, and clean up intestinal heat.

3. Salt has the effect of sterilization and anti-inflammatory, and salt can be directly smeared under the armpit when bathing. On weekdays, you can use cotton blocks soaked in salt water slightly lighter than sea water to carry around, and use it to remove sweat at any time.

4. After nosebleeds, you can stuff the salt soup into the nostrils with cotton wool, and drink 1 cup of salt soup at the same time, which can have the effect of stopping bleeding. If there is a small bleeding inside the mouth (such as bleeding gums, bleeding from a fish bone puncture and throat), rinsing your mouth with salt soup can promote blood clotting and play a natural role in stopping bleeding.

"Seven things to open the door, firewood, rice, oil, salt, sauce, vinegar and tea. This proverb shows that salt occupies an important place in people's lives. Tao Hongjing, a famous doctor in the Liang Dynasty, said: "Among the five flavors, salt is indispensable", which means that salt is the master of the five flavors.

Salt is indispensable in dietary seasoning and has a wide range of medicinal uses. The "Compendium of Materia Medica" says: "All diseases are useless.

Why? Li Shizhen analyzed: "Those who take the medicinal salt soup for the kidney will return the salt to the kidneys and introduce the medicinal qi into the internal organs; Those who use fried salt to replenish the heart with medicinal use have a bitter heart and are weak in salt, and they also make up for it with salt; Those who use medicinal salt to tonify the spleen will supplement their mother, and the spleen is the son of the heart; Those who are used to treat the accumulation of tuberculosis can be soft and hard; Those who use carbuncles and blood diseases will also be salty and bloody; Those who use it for wind and fever are better than heat; Those who use it to urinate and defecate can be salty and moisturized; For those with bone disease and dental disease, the main bone of the kidney is salty into the bone; Those who vomit for medicinal purposes, salty water gathering, can collect tofu synonymously; Those who use Gu and insect injuries should take them for detoxification.

The main component of table salt is sodium chloride. It has a salty and cold taste, and its functions are to clear heat, detoxify, cool blood, moisturize dryness, nourish the kidneys and laxative, and stop vomiting and inflammation.

Although salt is the "master of the five flavors", it is extremely uneatable. The harm of salt to the human body, especially the relationship between salt and blood diseases, has been recognized by Chinese medicine more than 1,000 years ago. For example, Tao Hongjing, a famous doctor in the Liang Dynasty, once pointed out:

People in the northwest are not tolerant of salty, and they have more life and less sickness, and people in the southeast have no desire for salty, and they have less life and more diseases, which is the effect of damaging people and hurting their lungs. Kou Zongzao of the Song Dynasty said: "People with asthma and edema should be completely banned."

Ming Li Shizhen further elaborated: "The smell of salt is salty, and human blood is also salty. Salty and bloody, blood disease does not eat more salty, and if you eat more, your pulse will condense and change color ......"The dialectical view of the relationship between salt and human health has been confirmed by modern medicine.

The effect of salt on hypertension was not deeply understood in the West until the beginning of the 20th century. Medical scientists first observed that the more salt you eat, the higher the incidence of high blood pressure.

For example, residents in the Tohoku region of Japan, who consume about 26 grams of salt a day, have a high blood pressure incidence rate of about 39%, and most of the causes of death are also high blood pressure and cerebral hemorrhage, and the Eskimo people consume about 4 grams of salt a day, where there are almost no hypertensive patients.

Salt is almost ubiquitous in food, so even if you don't eat salt specifically, the amount of salt contained in your daily food can meet your body's sodium needs. Although salt-free food can have the effect of lowering blood pressure, eating such dishes will definitely taste like chewing wax, and long-term use of salt-free diet, patients with poor kidney function may develop "low salt syndrome", so it is not advisable.

Proper control of salt consumption in daily diet is not only necessary for patients with a family history of high blood pressure and pre-existing hypertension, but also one of the basic principles of ensuring health for normal people. The daily salt intake is controlled below 10 grams, which is more suitable for the human body, and reducing it to less than 5 grams may reduce blood pressure and even eliminate high blood pressure.

<> everyone eats salt every day, and we also know that adding salt when cooking can play an important role in improving freshness and flavor, but do you know the other effects of salt? In addition to being edible, salt has a variety of effects, so if you want to know about it, you can take a look at it with me.
