Why do you want to control 6g of salt every day


Why do you want to control 6g of salt every day?



Before saying that you can eat the "salt" problem, let me tell you a little story. In the Romance of the Three Kingdoms, there is such a fragment. Cao Cao leads the teacher from Shandong to see the emperor's imperial Dong Zhao, but sees this person's eyebrows and spirits. Sufficient, and the world is in chaos, the vast majority of people face a lot of hunger, ask the reason, Dong Zhao replied: There is no other way, only 30 years of food. The "light" here, of course, does not only mean eating less salt, but this light food saying, we can understand that the diet is light, but the food is greasy, and the taste is not too heavy, of course, including eating less salt. In other words, the ancient Chinese have already had the concept of eating and drinking.

It is impossible to say that people can only consume 6g of salt a day. Many people use more than 6g of salt per day. But whether it is high blood pressure or healthy people, try to control salt intake every day. Do not exceed 6g, which is very important for your health.

Why is the concept of 6g salt proposed? For the human body, Na ion is a very important physiological substance. For maintaining electrolyte balance, maintaining the balance of internal and external cells, relaxing muscles, etc., Na ions are an indispensable nutrient for the human body, and the main Na in our human body. The source is obtained by ingesting salt, which contains about 0.4 g of sodium ion per g of salt (NaCl). In general, the daily intake of 4.5 g of salt is enough to maintain the body's need for Na. Therefore, the limit of 6 g of salt per day is enough to supplement our daily needs.

If the long-term eating is too salty, the intake of Na will exceed the standard for a long time, what harm to the body? As the saying goes, it’s too late. Although Na is a physiological substance that is important to the human body, excessive intake can cause certain harm to the body.

1. Long-term excessive intake of Na, although the human kidney has a certain regulatory function, it will try to maintain the balance of electrolytes, but long-term excessive salt intake will also increase the burden on the kidneys, kidneys that work under high load for a long time. It is also possible to cause damage to kidney function due to a high-salt diet.

2. Long-term high-salt diet, the excess of Na ions in the body, if not excreted in time, will cause sodium retention, which is an increase in blood volume, leading to an increase in blood pressure. The study found that people who consumed more than 15 g of salt per day had a prevalence of more than 10%.

3. Long-term high-salt diet, excessive Na ions in the body, will change the osmotic pressure of blood, leading to edema of vascular smooth muscle cells, resulting in narrowing of the vascular lumen, also raising blood pressure, and high-salt diet also has certain blood vessels. Direct damage.

4. Long-term high-salt diet, excessive sodium will competitively increase calcium excretion, and will also affect the balance of human bone metabolism, which will increase the risk of osteoporosis.

5. Long-term high-salt diet has adverse effects on the digestive system (gastric mucosal injury, gastric ulcer), respiratory system (increased asthma incidence, high risk of upper respiratory tract infection), diabetes incidence, etc. Our attention.

Therefore, the problem of intake of this salt is neither insufficient, but more should be noted that not excessive. Through the introduction, we can also see that the high-salt diet, the main cause of harm to the body is the excessive amount of Na ions. Therefore, our understanding of this "salt" should not only stay in the salt of our daily cooking.
In addition to the daily cooking salt, there are many other sources of “Na” in our daily diet, such as nitrite used in processed meat products, MSG we eat, salty flavors, and processed foods. Baking soda, the preservative sodium benzoate in some foods, and some nutritional supplements are all sources of Na. If you want to control salt well, you should pay attention to these aspects in daily life. Ingestion.

Although we often talk about the concept of 6g salt, it is actually very difficult to measure. Stir-fry a dish, a family to eat, how much salt to add to the scale to be called and then average? These are not well measured, but at least we realize that if you eat too salty, it will cause harm to your health. Try to keep the diet as light as possible, and take care to avoid the "invisible salt" mentioned above. Into, for the health of the body, its benefits must be huge.
For the intake of salt, it is not necessary to be static. For example, workers who are engaged in manual labor in summer have more sweating daily. Of course, it is no problem to eat a little salt. In the case of severe diarrhea, in addition to adding water, Also pay attention to the additional electrolytes such as Na, K ions, so the concept of supplementing 6g salt is a healthy health concept, but it should not be rigid
