Would humanity have survived without salt?

Since the beginning of human existence, we have been blessed and nurtured by the earth, and the earth has always been our home for survival. There are many things in our daily life that have become indispensable and irreplaceable things in our lives, such as cars in life, the Internet and so on, some high-tech products have become an irreplaceable part of our lives. At the same time, there are some things, such as salt in life, which has also become something that we Chinese or people all over the world are demanding.

If there was no table salt, would humans still be able to survive? To be determined, of course. This is manifested in the following points.

1. Without salt, we can't pickle food. First of all, in ancient China, people could only use some experiments in life to manage some of our food. During that period of time, people could only use some of the table salt in their lives to manage some of our food, and during that period of time, people could only use some of the table salt in their lives to marinate some of our food.

Table salt can sterilize food and have a shelf life on pickled food.

It will also be greatly improved, which is more conducive to our preservation. Nowadays, this method is still used to marinate food in many regions, such as kimchi in the northeast and in the south.

of bacon and so on. <>

2. Humans can't cook delicious food. Secondly, we wouldn't be able to cook delicious food without salt. It can make people improve the freshness of the food, and it can also stimulate the original taste of the food itself, which is more delicious and more delicious, which is also a role of seasoning.

Third, salt can also help us heal diseases. The last point is that the state has added a lot of trace elements, such as iodine, to its promise.

In many areas, due to the fact that their residents are deficient or have too much iodine, it can lead to our thyroid lesions with hyperthyroidism.

or hypothyroidism. performance.

No, humans cannot live normally without salt intake, not only humans, but also animals need to consume a certain amount of salt to live normally.

If there is no salt to replenish the ingredients in the human body, then the balance in the human body will be disturbed, and too much water will cause dehydration, and human beings will not survive.

I don't think so, because salt is a thing that replenishes the body's essential elements, and if you don't, this element will be missing.

1. Mental malaise.

One of the components of table salt is sodium, which is essential for the nervous system to transmit information in the human body, and muscle contraction and heart beating are closely related to sodium ions. When people lack salt or do not consume enough salt, it will lead to mental malaise and be very unfocused, which is not conducive to normal work and life, let alone fighting.

2. Increase the incidence of cancer.

When salt intake is insufficient, the acidity content in the cells will increase dramatically, which in turn will damage the body's DNA cells and induce cancer.

3. Muscle cramps at night.

This is due to sweating and excretion, which excretes some of the salt from the body, and the lack and passage of salt will cause the space between polyp cells to shrink, which in turn will increase the pressure on the peripheral nerves, causing the body to feel pain.

4. A series of mental health problems.

When a person eats too little salt, it will cause the sodium content in the body to be too low, and symptoms such as loss of appetite, weakness of limbs, and dizziness will occur; Some severe people also experience nausea and vomiting, anorexia, arrhythmia, blurred vision and other phenomena.

5. Low sodium and hypochloremia.

The main manifestations are muscle weakness and weakness, nausea and vomiting, headache and drowsiness, muscle cramps, neuropsychiatric symptoms and reversible ataxia.

6. Increase mortality.

This is primarily data from a study seen in patients with type 2 diabetes, and the findings suggest that less sodium is associated with an increased risk of death in patients with type 2 diabetes.

After the discovery of salt, the demand became higher and higher, so salt later became an important item in **There is even a record of salt in Chinese history books. These records first appeared in 800 BC. In ancient China, for example, our ancestors called natural salt "halogen" and artificially processed salt "salt", and in the wilderness era, people found that salt was edible and that people who ate salt were stronger.

Long before the dawn of civilization, human life depended on physiological instincts. There are tribes that live in areas rich in salt and some in areas with little salt. Driven by their survival instincts, they are stupid and find that the life force of the salt-rich area is stronger, and gradually move to the salt-rich area.

About 5,000 years to 10,000 years ago, human beings developed faster and faster. At that time, the number of humans in the world increased dramatically, and the range of hunting gradually expanded. Because more and more people began to catch prey, there was a shortage of prey for some time.

At this time, the intake of meat by humans was becoming less and less, and the cultivation industry also developed. Vegetables are making up more and more of people's diets, eventually reaching 90%. The first place where salt was found was the sea.

The salty taste brought by the sea first made people understand that sea water contains salt. In ancient China, salt was boiled in seawater. Therefore, in ancient times, the salt-rich zone was the seaside.

Humans moved their lives to the seaside, and then civilizations, writing, and technology multiplied, and thus knew the wisdom of refining salt.

Seeking salt is a biological instinct due to our body's need for salt, but it is inextricably linked to diet. Vegetarians must know that extra salt is available in **, while meat-eaters don't need it. However, excessive salt intake can also bring many drawbacks, such as high blood pressure, heart disease, kidney disease, etc.

People are becoming more and more dependent on salt. Many people will find that if they don't eat any salt, they will feel weak. Why?

This is related to sodium chloride, the component of the salt. Sodium chloride is very important for the balance of the human bodyBecause our blood, sweat, and tears often contain salt, people need salt to function properly. If there is no one, the body is out of balance.

Salt was discovered in ancient times, because people in the past ate more miscellaneous food, they would judge the hunt or eat some wild vegetables, wild chong can supplement the rich sodium, human beings are more refined in their diet, and the things they eat are relatively clean, so they will be deficient in sodium.

It was discovered more than 5,000 years ago during the Yanhuang period; Because the human body needs to supplement sodium in time, if the amount of sodium in the human body is particularly small, the limbs will be weak, and even the symptoms of dizziness will appear in the body, and salt can supplement sodium to people, because in the past, it was mainly based on meat, and meat contained the sodium that the human body needs.

Humans discovered salt about 6,000 years ago; Because before the discovery of salt, people did not eat salt, but they would eat a lot of foods containing salt, such as animal blood or animal meat, so they could also maintain daily necessities, but the food we eat now will be particularly rich, and some foods do not contain salt, so they need to take extra salt.

Salt has been discovered in the time of the ancient ape-man, and in the past, people would have obtained salt through some other food, so there is no such thing as not eating salt.

Salt is one of the most important and controversial minerals in human history, and there have been more than 14,000 uses for refined salt to date, not only for food preservation, ** wounds, but also for many other uses such as chemical processing, oil, and natural gas. Even in the past, a lot of workers were paid with salt. The average human body contains about 40 teaspoons of salt, which is almost 1% of the body.

Every time you cry and sweat, your body loses some salt. If not replenished in time, the body may suffer from hyponatremia, which can cause fatigue, vomiting, seizures, and even death. What happens if you lose salt permanently?

It's not just animals that need salt, but so do food, and desalination alone will wipe out all of our underwater algae. Take the photosynthesis on the planet in half, and then the plants on land will follow. Soon, we will have the problem of too much carbon dioxide and not enough oxygen.

At that time, our climate will become more irritable, fluctuating back and forth between extreme heat and low temperatures, and the phenomenon of hurricanes will increase dramatically. In addition, in addition to bad weather, food shortages and lack of oxygen can also occur. However, you may not be able to pay attention to these at this time, as you may experience dizziness, headaches, and extreme fatigue.

If the person is in worse health, they may also experience problems with body numbness and chest pain. Also, it's best to pray that you don't have heart problems, otherwise your condition may be more dangerous. At this time, it is advisable not to run to the hospital, as it may be full.

You can choose the nearest convenience store, and if you're lucky, there are some salt substitutes like potato chips on the shelves. Of course, this is only hypothetical, in the face of large-scale desalination scenarios.

If table salt just disappears, you may go anywhere useless. Maybe now everyone thinks that there is still a lot of salt in the world, and we don't need to worry about it at all, but in fact, with the pollution of the oceans by our human beings, the amount of available salt is also decreasing, if this continues, the world's salt will be exhausted one day, and one day in the future, our children and grandchildren will have a shortage of salt resources, and then human beings may face serious survival problems. Brother Yi hopes that the friends who have watched ** can work hard to reduce carbon emissions in their daily life, use as little plastic waste as possible, and make our oceans less harmful.

Mild salt deficiency in the human body can lead to dizziness, fatigue, fainting when standing upright, normal or increased urine output, and low urine specific gravity. Moderate salt deficiency will cause symptoms such as loss of appetite, increased heart rate, muscle cramps, headache, decreased urine output, weak pulse, loss of elasticity, nausea and vomiting.

If human beings lose their time, first of all, they may feel a lack of condiments in their diet, and in the process of losing weight in everything they eat, their bodies may also have some problems, after all, if they do not break their promises, they may also have some adverse effects on their bodies.

Feeling sluggish; Cramps occur during sleep at night.

1.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. However, eating more salt is also harmful to the human body. The results of the scientists' study show that:

Salt can "hydrate" the human body, that is, salt has a certain adsorption force on water, and the amount of salt in the human body increases the amount of water required accordingly, so that too much water is trapped 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.

2.Animals are the same, but they get Na ions in a different way than humans, humans can consume salt every day, while animals indirectly absorb Na ions through food or water, so to some extent, animals also need "salt", but the way they take in it is different from that of humans.

3.When humans transitioned from the nomadic era to the agricultural era, the food structure changed to grains and vegetables as the staple food, and they lacked salt from the animals. Because the plant contains very little salt, the ancestors began to look for traces of salt out of physiological needs.

Animals don't eat salt, but people can't do without it? How did primitive man survive without salt?

People live without salt.

When the human body lacks salt, the concentration of body fluids decreases, and electrolyte imbalances can cause physical discomfort.

If you don't eat for a long time, your body is tired, and you have no energy.

Animals do not eat salt, but they do get it from many sources, such as plants and soil.

Primitive man obtained it from food, stone mines, etc.

If there were no salt in the world, the oxygen produced by plants on Earth would be halved, and terrestrial plants would die in large numbers. It won't be long before humanity faces a dilemma of too much carbon dioxide and a serious shortage of oxygen.
