Reminder: Eating too much salt is very harmful. If you don’t get rid of it in time, 4 kinds of diseases will soon come to you!
"Salt" is the most common condiment in life, and it is also known as the first of all flavors!
Relevant studies have shown that the main component of salt is sodium chloride, which will precipitate two components, sodium ion and chloride ion, after entering the body.
Under normal circumstances, these two substances are necessary components of the body. They play a role in maintaining the osmotic pressure of extracellular fluid and acid-base balance. At the same time, they also play a certain role in maintaining nerve and muscle irritability and regulating physiological functions. effect!
However, this does not mean that the more salt you eat, the better. According to the "Dietary Guidelines for Chinese Residents" , a healthy adult should consume no more than 6 grams of salt per day. The organization recommends that everyone eat the standard of sodium.
A related research survey shows that the average daily salt intake of Chinese residents far exceeds this standard, even reaching more than 10 grams , and the number of Chinese people with excessive salt has reached about 75%.
Excessive salt intake can lead to the following hazards:
1. Hypertension
There are many studies and investigations showing a strong link between excess salt intake and high blood pressure. Because after ingesting a large amount of sodium ions , in order to maintain the balance of body fluids , extracellular fluid will increase accordingly.
At the same time, excessive salt content will also stimulate the thirst center , causing the human body to drink a lot of water , and the blood volume will increase accordingly .
Hypertension is a high risk factor for cardiovascular disease. According to relevant research surveys, nearly 1.65 million people in the world suffer from cardiovascular disease caused by excessive salt intake every year;
2. Kidney damage
The kidney is one of the most important metabolic organs in the human body. Its basic function is to generate urine and maintain the balance of water, electrolytes and blood pressure in the body.
Relevant studies have shown that only a small part of the salt entering the human body will be used by the body, and the remaining 95% of the salt is excreted through the kidneys in the form of urine . Eating a lot of salt will increase the metabolic burden on the kidneys.
If the salt cannot be discharged in time, it will also develop into multiple problems such as water and sodium retention and edema . Moreover, some studies have pointed out that excessive salt intake will lead to increased protein content in urine , and proteinuria is precisely one of the typical manifestations of kidney damage;
3. Osteoporosis
Research studies have shown that sodium ions need the assistance of calcium ions in the process of being excreted from the body. Normally, the body loses about 26 mg of calcium ions for every 1000 mg of sodium ions excreted .
That is to say, the more sodium ions that need to be excreted, the greater the consumption of calcium. Over time, it can increase your risk of developing osteoporosis. In addition, too much calcium in the urine increases the risk of kidney stones;
4. Respiratory infection
Excessive salt intake will stimulate the thirst center, but also inhibit the activity of respiratory cells and reduce the secretion of oral saliva. In this case, the ability of the respiratory tract to clean itself and fight pathogens is reduced , which increases the chance of pathogens infecting the respiratory tract.
In addition to the above four hazards, excessive salt intake will also promote insulin secretion and increase fat storage, which may lead to obesity in the future and increase the risk of diabetes.
Therefore, from a health point of view, excessive salt intake is not beneficial. Everyone should minimize the addition of salt and condiments when cooking to maintain the original taste of food.
