Ms. Zhao is 42 years old this year. She is the old and young. . Her life is under heavy pressure, so she works very hard and now works as a regional manager in a company.
A year ago, Ms. Zhao suddenly felt a dull pain in her stomach. Because she had suffered from stomach disease before, this time, thought it was an old problem and had again, so she took some medicine to treat stomach disease, so she didn't take it to heart and continued to work.
It took a while, until half a month ago, Ms. Zhao began to experience symptoms of nausea and vomiting . At the same time, was accompanied by diarrhea and , and the excreted feces also contained undigested food. As the symptoms continued, Ms. Zhao began to panic, so she put down her busy work and went to the hospital for treatment.
It doesn’t matter if you don’t check it. When you check it, Ms. Zhao was found to be gastric cancer . The doctor learned from the conversation with Ms. Zhao that Ms. Zhao's father also died of gastric cancer. The family likes to eat pickled foods, such as smoked fish, bacon , pickled , which are common foods on their table.
From this, doctors inferred that the main reason why Ms. Zhao is related to the long-term high-salt diet .
I believe that everyone will be shocked when they see this. Eating too much salt may also lead to gastric cancer? In addition to gastric cancer, what other effects will it have on the body? How should we choose salt? Today, I will use this article to learn about the poor diet of high-salt and how to choose the right salt.
Harvard Research: Eating too much salt may increase the risk of death
In our daily life, salt is an indispensable seasoning. As the saying goes, "Five flavors are the first, and all flavors are the first". From this we can see how people in the past like salt, which may be because of the status of salt in ancient times.
In the late Ming and early Qing dynasties, salt belonged to the controlled product and was monopolized by the government. At that time, the salt seller was called a salt merchant. If a salt merchant wanted to transport and sell salt, he had to pay enough money to the salt transport yamen and get the salt sales certificate before he could sell salt in the place designated by the government. If you sell salt privately without a certificate, it is a crime.
So, at that time, the price of salt was very high, and ordinary people basically seldom eat salt. It was not until the end of the 18th century that salt became a condiment that ordinary people could enjoy. Perhaps because of the retaliatory diet , many people like to put more salt when cooking, so that has developed a high-salt dietary habit , which has been passed down from generation to generation.
However, eating too much salt is not good, so Haval University once conducted a survey and research on people who like to eat salt.
This study included more than 500,000 volunteers from , and were between 0 and 69 years old. Haval University recorded more than 1,800 premature deaths in for more than ten years through a questionnaire.
Through the analysis of the data, Haval University researchers found that the more people who like to eat salt in have a higher risk of premature death and a shorter life span. At the age of 50, men who like to eat salt reduced the lifespan of .5 years for on average, while women reduced the lifespan of .28 years for on average.
In other words, people who consume more salt in may increase the risk of death by 28%.
This is because, first of all, a high-salt diet may induce hypertension .
Lu and others found that a high-salt diet will increase the content of sodium ion in human cells, potassium ion content lower , forming osmotic pressure, causing water to enter the cells, causing edema of cells in blood vessels, causing blood vessel to become narrower , reducing blood flow , and increasing blood pressure .
In addition, Frans et al. found that a long-term high-salt diet will also cause the catecholamine concentration in plasma to increase , which accelerates heart rate , enhances myocardial contractility, and increases cardiac output. At the same time, it can also activate central nervous system , causing sympathetic nerve to excite , causing blood pressure to rise.
Secondly, a high-salt diet may also lead to gastric cancer .
The reason why Ms. Zhao in the story suffers from gastric cancer is inseparable from her high-salt eating habits in daily life. Studies have found that if the human body consumes a large amount of salt for a long time, it may form an osmotic pressure of in the gastric mucosa cells and the outside world, causing damage to the gastric mucosa and causing damage, causing erosion, congestion, ulcers and edema , which will greatly increase the chance of gastric mucosa cells becoming cancerous.
In addition, long-term high-salt diet can also reduce the secretion of gastric acid , thereby slowing down the synthesis of prostaglandin, increases the chance of pathological changes in stomach and increases the risk of gastric cancer.
It can be seen that maintaining a high-salt diet for a long time will not only increase the blood pressure , increase the incidence of hypertension, but also increase the risk of cancer, thereby increasing the risk of death and reducing life span. Therefore, we should pay attention to our diet in our daily lives. If the body has the following abnormal symptoms, it may be because we eat too much salt. should control .
The following symptoms appear in the body, which means that you eat too much salt. It is time to control
As the saying goes, Everything is moderate, everything will be reversed , and the same is true for salt. Although salt, as an important seasoning in life, can make food more delicious, we should also pay attention to the "degree" when using salt. When it exceeds this "degree", our body will have some symptoms. sends a signal , prompting us to be restrained.
1. Frequently thirsty
. Eat too salty food and we will want to drink water. This is a common idea. However, have you ever thought about why your body wants to drink water after eating too much salt?
This is because the main component of salt is sodium chloride , which plays an important role in maintaining the electrolyte balance of in the human body. When too much salt is intake, the balance of electrolytes in the human body will be unbalanced, causing osmotic pressure inside and outside the cells, causing to dehydrate in tissue cells. At this time, the nervous system of the brain will issue instructions to drink water to replenish in tissue cells.
2, frequent urination
Do you know that eating too much salt may also lead to frequent urination.
If there were no symptoms of frequent urination before, and if you had too much salt recently, you had symptoms of frequent urination at the same time, you should pay attention at this time and it is time to reduce your salt intake.
The research team at Nagasaki University in Japan conducted salt reduction guidance for 321 volunteers with frequent urination. The results showed that the 223 successful salt reduction patients had reduced the number of urination by an average of 2.1 times a day, while those who failed to reduce salt did not improve their number of urination.
Therefore, they concluded that salt and the frequency of urination are related to , and reduces salt intake can reduce the number of urination times .
3, osteoporosis
What? Eating too much salt may also cause osteoporosis ? Yes, you read that right.
Titz et al.'s research team gave rats a high sodium chloride diet intervention. The results showed that a high-salt diet can lead to the rat's urine sodium and urine calcium excretion in rats, which in turn leads to the reduction of in the rat's tibial bone formation , and bone trabecular sparse and decay . Excessive urinary calcium excretion can cause calcium metabolism imbalance, further affecting to normal calcium and phosphorus metabolism , leading to bone loss and osteoporosis.
study confirmed that the human bone density is negatively correlated with urinary sodium level, and it is concluded that excessive salt intake in diet may lead to the occurrence of osteoporosis .
It seems that when our body experiences frequent thirst, frequent urination, and osteoporosis, it may be that the salt intake is large, and we need to pay attention to the use of salt. Of course, in addition to paying attention to the amount of salt, the type of salt is also very important. Choosing salt that suits you can also have some positive impact on your health.
Choose the right salt to protect health
With the development of science and technology and the progress of the times, people's living standards have been improved to varying degrees, and the requirements for living conditions are getting higher and higher. Therefore, the functions of salt have also become diverse, from a simple condiment to a food that combines seasoning and nutrition.
For patients with hypertension, low sodium salt can be selected.
From the above we learned that a high-salt diet is one of the main factors that induce hypertension. Common table salts in life are mainly composed of sodium chloride, while low-sodium salts use magnesium chloride and potassium chloride to replace some sodium chloride, reducing its content to less than 75%, thereby reducing the sodium ions intake in the body.
Potassium ions, like sodium ions, are one of the necessary elements of the human body. However, the effects of potassium ions and sodium ions are completely opposite. Potassium ions can not only reduce blood pressure through diastolic blood vessels, but also reduce vascular resistance . You can also adjust the sodium-potassium balance in the body by through urinary sodium to lower blood pressure.
In addition, potassium chloride is basically no different from sodium chloride in terms of taste and taste, so using low sodium salt to cook will not affect the taste of the dish.
For people with iron deficiency anemia , it is recommended to choose iron fortification nutrients.
iron ion also plays an important role in our body. It can combine with the human protein to produce a large amount of myoglobin and hemoglobin to maintain normal growth and development of the body.
, and iron-fortified salt is selected as the glucose ferrous , which is most easily absorbed by the human body, and mixed with refined salt. It can supplement iron ions well for the human body and has a certain auxiliary effect on the treatment of iron deficiency anemia.
is written at the end
In short, long-term high-salt diet is very bad for the body, and may induce hypertension and cause cancer, thereby increasing the chance of death . Therefore, we should pay attention to the amount of salt used in our daily life.
In addition, in addition to paying attention to the "degree" of salt, we should also choose salt that suits our own situation according to our own situation, so that it is beneficial to our health.
