Why do people eat salt? Why do people eat salt?

Salt contains iodine, which is indispensable for the human body. It also contains sodium, which in the human body is to eat more and eliminate more, eat less and eliminate less, and do not eat and do not excrete.

However, salt should not be eaten too much, and it is best not to have too much taste of food. MSG, can enhance umami, but should not be eaten more, eat eggs, vegetables, etc

Organisms contain ions in their bodies, and ions are the factors that maintain the balance of the environment inside and outside the cell, which in turn affects the internal condition of the human body! There are many or too few of these elements, but not too much and not too little! Since humans evolved from seawater (rich in sodium), the presence of sodium ions in the body is required to complete the mechanical reaction in the body!

Since table salt is made of sodium chloride, we need it! There is also iodized salt because of the presence of iodine, which is in line with the needs of the human body! Sodium deficiency can lead to edema, and iodine deficiency can lead to big neck disease!

Salt is a condiment commonly used in cooking, eating, and food processing, but why do people need to eat salt? In this article, I will explain why people need to eat salt from a physiological, cultural, and historical perspective.

From a physiological point of view, the human body needs salt to maintain physiological functions in the body. First of all, sodium in salt is an important element in controlling fluid balance in the body. When the body needs to be hydrated, the kidneys release more urine to flush excess water out of the body and excrete excess sodium in the process.

Therefore, when we sweat or feel thirsty, we need to drink water and consume salt to maintain the balance of water in our body. In addition, sodium is also necessary for the functioning of the nervous system, heart and muscles, so consuming the right amount of salt can keep the body functioning properly.

In addition, salt is also a condiment that is culturally and historically embedded in our diet. From around the 6th century BC, salt became a staple of exchange and taxation in China and other East Asian countries. This historical and cultural tradition has also led to a deep understanding and widespread use of salt by East Asians.

On the surface of the cultural level, people love the taste of salt. Our taste buds are naturally looking for sweet, salty, sour, bitter and other flavors, and saltiness is one of the more acceptable ones.

In the modern food industry, salt is also a commonly used food additive. The addition of salt can extend the shelf life of food, improve the taste and enhance the color of food. Still, excessive salt intake may lead to health problems such as high blood pressure, edema, obesity, and cardiovascular disease.

Therefore, it is important to keep your salt intake as low as possible in order to maintain your health.

If you consume too much salt, there are a number of undesirable consequences. Especially in developed countries, excessive intake of salt in the diet often leads to cardiovascular diseases and diseases of organs such as liver and kidneys. Therefore, in modern dietary habits, many countries and regions have set standards such as salt intake to protect public health.

In summary, humans need to consume the right amount of salt in order to maintain a stable state in the body and meet the taste needs of individuals. However, excessive intake can create a range of health problems. Therefore, maintaining proper levels of salt intake is essential for the health of the body.

People need salt because salt is a mineral that the body needs to maintain normal water balance and blood pressure. Sodium ions in the human body can promote the normal metabolism of cells and the normal function of neuromuscular meat, and at the same time, it can also maintain the osmotic pressure and acid-base balance of the blood. However, excessive salt intake can also cause harm to the body, such as increasing the risk of high blood pressure, heart disease, stroke, etc.

Therefore, people are advised to pay attention to the appropriate amount and not overdo it while consuming salt.

People need to eat salt because salt contains some important minerals that are essential for the human body, such as sodium, chlorine, etc. Sodium and chloride have important physiological functions in the human body, they are necessary components to maintain the body's water and electrolyte balance, maintain blood osmotic pressure, participate in important physiological processes such as nerve excitation and muscle contraction. However, sodium and chlorine are found in very small amounts in food and cannot be synthesized by the human body, so they must be consumed through diet.

On the other hand, moderate intake of salt can also improve the taste and freshness of pure bright kernel food. After adding salt to food, it can increase the flavor of the food and make it more delicious and tasty; At the same time, salt can also inhibit the reproduction of microorganisms and play a role in preservation.

It is important to note that although salt is good for the human body, excessive salt intake can also bring bad effects, such as increased risk of cardiovascular disease, obesity and high blood pressure. Therefore, it is recommended to properly control salt intake in the diet, and it is recommended that adults consume no more than 6 grams of salt per day.

Eating salt can be more conducive to the body's metabolism, and is conducive to enhancing the ability to avoid epidemics, and has certain benefits for preventing colds and constipation.

People exercise every day to breathe and consume energy, so salt is an indispensable substance for the human body. It can better boost the body's metabolism, raise body temperature, and enhance the body's immune function. In addition to this, it also has a certain osmotic pressure, and the blue segment can be involved in the communication of the nervous system as well as muscle contraction.

In hot weather, if the body sweats a lot, water and salt will be lost a lot, which will reduce the contraction ability of the muscles and the transmission function of the nervous system, causing spasms, and the lack of salt in the body will also have an impact on the myocardium.

Therefore, salt is a very important part of the human body, but it should be reminded that people who exercise less and sweat less can not use too much, especially people with high blood pressure should also pay attention to salt intake. Once overdosed, it is also very detrimental to the health of the body.

1. Salt can provide a large amount of sodium, which plays a variety of vital roles for the human body, which can promote the metabolism of proteins and carbohydrates, the transmission of nerve impulses and muscle contraction, and also regulate the consumption of hormones and cells to oxygen, control urine production, thirst and produce fluids.

2. Salt is not only an important condiment, but also an indispensable substance for maintaining the normal development of the human body. Salt can regulate the balanced distribution of water in the human body, maintain osmotic pressure inside and outside cells, participate in the formation of gastric acid, promote the secretion of digestive juices, and increase appetite.

It is important to note that eating food that is too salty every day can trigger some related diseases. For example, high blood pressure, high blood viscosity, etc., so it is best to consume no more than 6g of salt every day, and the food consumed should be as light as salt as possible, which is more conducive to our health.

Introduction to table salt

Table salt refers to different sea salt, well salt, mineral salt, lake salt, soil salt, etc. Their main ingredient is sodium chloride, and the state stipulates that the sodium chloride content of well salt and mineral salt shall not be less than 95%. Table salt contains barium salts, chlorides, magnesium, lead, arsenic, zinc, sulfate impurities.

We stipulate that the barium content should not exceed 20mg kg. Excessive magnesium and calcium content in table salt can make the salt bitter, and high fluoride content can also cause poisoning.

Edible salt is iodized salt made by adding a certain amount of iodine to refined salt, crushed washing salt, and sun-dried salt. The iodine in salt can only be biologically active in the human body after it is converted into iodine ions. The properties of iodide are extremely unstable, easy to decompose, volatilize and fail.

Salt is not only an important condiment, but also an indispensable substance for maintaining the normal development of the human body. People eat salt because it can maintain the osmotic pressure of extracellular fluid, which plays an important role in the dynamic balance of the human internal environment, and is one of the indispensable substances for maintaining the normal development of the human body. Salt is rich in sodium.

Sodium can promote digestion, enhance appetite, assist metabolism, raise body temperature, enhance immunity, and prevent constipation, colds and hangovers. However, it should be noted that excessive salt intake can also cause some related diseases, so it is best for the human body to use no more than 6 grams of salt a day.

Table salt refers to different sea salt, well salt, mineral salt, lake salt, soil salt, etc. Table salt contains impurities such as barium salts, chloride, magnesium, lead, arsenic, zinc, sulfate, etc. The excess magnesium per mu and excessive calcium content in the salt can make the salt bitter, and the high fluoride content can also cause poisoning.

In ancient times, there were many kinds of salt, and they were divided into colors such as snow, peach blossom, green, purple, white, etc. From the point of separation: sea salt is made by sea brine decoction, well salt is made by well brine decoction, alkali salt is made by squeezing alkaline soil from trapped silver, pool salt is dried from pool brine, and cliff salt is born between soil and cliffs.

Sea salt, well salt, and alkali salt come from people, and pool salt and cliff salt come from the sky. The "History of the Ming Dynasty" records: "The salt of Jiezhou is knotted, the salt of Ningxia is scraped to get it, the salt of Huai and Zhejiang is boiled, the salt of Sichuan and Yunnan is drawn to the well, the salt of Fujian and Guangdong is accumulated, the salt of Huainan is fried, the salt of Huaibei is dried, and the salt of Shandong is fried and dried

Salt, also known as sodium chloride, is a white crystal composed of a sodium ion and a chloride ion, which is the seasoning of people's delicious food. I don't know if you have found it, every time you cook a dish, you can have no seasonings such as MSG, but salt must be put in, why is this a dish? Why do people need to eat salt, let me answer your questions.

Salt is generally referred to as sodium chloride, which is a white crystal composed of one sodium ion and one chloride ion. Sodium and many other inorganic salt (i.e., mineral) ions, such as potassium, calcium, magnesium, chloride, bicarbonate and phosphate, are essential substances for the human body.

Humans contain about 40 millimole of sodium ions per kilogram of body weight, of which about 50% are distributed outside the cell, about 10% are present in the cell, and about 40% are contained in the bone matrix. Sodium salt is an important substance to regulate the water balance in the human body, and the kidneys use sodium to reabsorb water to maintain the balance of sodium and water in the human body, and also maintain the normal volume of body fluid and circulating blood in the human body. Sodium ions are also involved in the excretion of acidic metabolites in the kidneys, contributing to the maintenance of acid-base balance in the body.

The chloride ions in table salt are an important component of stomach acid. In addition, sodium and chloride ions are also involved in the bioelectrical activity of nerves, muscles, and cells of certain glands.

If people do not eat salt for a long time or eat too little salt, it will cause the sodium content in the body to be too low, loss of appetite, weakness of limbs, dizziness and other phenomena, and in severe cases, anorexia, nausea, vomiting, rapid heart rate, weak pulse, muscle spasms, blurred vision, weakened reflex activities and other symptoms. But eating too much salt can also be harmful to your health, for example, and may cause high blood pressure. Therefore, the World Health Organization recommends that adults eat no more than 5 grams of salt per day.

The question of why people eat salt is like why people drink water.

People lose a lot of salt when they sweat during their usual exercise, so for example, for manual workers or athletes, they need to replenish salt water or eat a little salty. However, for example, infants or mental workers who exercise less, they should eat lightly.

In addition to sweat, such as tears, snot (all body fluids), contain a small amount of salt, so you should supplement with some salt.

I'm just thinking differently, I'm not a doctor, and I don't think I know less than a doctor).
