Salt, chemical name NaCl, we should all know that it is particularly important for health and is one of the essential nutrients for human body. For example, it can adjust the balance between body fluids and osmotic pressure. Between cells and diluted tissue fluid, where to run is similar to kneading dough, adding more water to dough, and adding more water to dough to maintain dynamic balance.
? In addition, it also maintains the acid-base balance of body fluids, which is closely related to the excitability of muscles and can participate in the absorption and utilization of food. It can be said that the results are remarkable and people love "salt"! ?
However, it is too late to talk too much, just like an old saying: if you talk too much, you will lose. If you talk too much, you will make mistakes. It is also appropriate to use salt. If you eat too much salt, you will lose!
So, how much is the salt?
The normal intake of salt should start with sodium, which is 6-7 grams for normal adults. The maintenance of this quantity is a dynamic balance. When you go in, you come out. Of course, going in is eating and drinking, and going out is pulling and sweating. I thought my forehead was soaked with sweat after running this morning. It turned out to be sparkling salt! )
?
The human body doesn't need much sodium. It needs to take1000-2500mg a day, which is only one or two grams. This means sodium, not salt. Converted into salt, the sodium content of salt is about 40%, divided by 1 equals 2.5-6.5g.. Therefore, the World Health Organization recommends that adults should eat 5 g of salt per person per day, and the Nutrition Society of China suggests that the intake of adult salt should not be 5 g per person per day according to the diet of China people.
Some friends may ask, how do you know if your daily salt content exceeds the standard? Is there a simple and feasible measurement method? Sure! 6 grams of salt, the amount of a beer bottle cap, is 2 grams of salt per meal. In fact, it is very difficult for many friends who are used to paying attention to taste. According to a recent survey by the Ministry of Health, China residents consume an average of 8 8- 10/0g of salt every day. If they regularly eat junk food, it will exceed15g every day!
Look at this photo again. This is the salt consumption in a representative area. What district do you think you are from? Is it holding you back?
In fact, no matter which district, it has exceeded the recommended intake, which has made great contributions to improving the average, especially in northern cities, and even Cantonese people who claim to have a light taste have exceeded the standard. How do you feel about this? Shh! For the sake of health, this amount of salt must go down quickly! ? As for the harm of eating too much salt to health, it has actually been mentioned from the beginning. Here, I will focus on the six-level harm caused by eating too much salt:
? Let's start with the main hazards. People who eat a high-salt diet for a long time will certainly look older and have many wrinkles, just like shriveled cucumbers, which are full of wrinkles because of lack of water. The so-called beauty is mostly born in the mountains, not by the sea.
Secondly, people who eat a high-salt diet for a long time will lose their resistance and easily cause colds; Because high concentration of salt will inhibit the activity of respiratory cells and their disease resistance, at the same time, saliva will be reduced, lysozyme in the mouth will be reduced, and the chance of upper respiratory tract virus and bacterial infection will be increased, and the most easy manifestation is a cold;
In addition, the fourth hazard of excessive salt aggravates diabetes, because too much salt will increase amylase activity, leading to too high blood sugar concentration in the body, and diabetes will come in the long run!
Let's talk about the third-degree harm of excessive salt, which leads to osteoporosis. This is because the kidneys excrete excess sodium every day, and every time they excrete 1000 mg of sodium, they consume 26 mg of calcium. The more sodium needs to be removed, the greater the consumption of calcium, which will inevitably affect the normal growth of bones, especially the elderly who lack calcium. The secondary harm of excessive salt: aggravating hypertension; This should be the most talked about and possibly the most severe situation. According to recent data, the number of hypertensive patients in China has reached 330 million, which is more than the entire population of the United States. Moreover, scientific research also shows that excessive sodium intake is positively related to the incidence of hypertension, and the probability of people with high salt diet is much higher than that of people with low salt diet. The prevalence of hypertension in China is obviously different between the north and the south, which is directly related to the salt intake in the north and the south.
Finally, the primary harm of excessive salt: inducing cancer, especially esophageal cancer and gastric cancer; Excessive salt intake will destroy the gastric mucosal barrier, increase the susceptibility to carcinogens, and lead to an increased risk of gastric cancer. Look at the picture. This is the latest cancer distribution map in China. As can be seen from the figure, the northern part of China is the high incidence area of esophageal cancer and gastric cancer, which is also the area with high salt intake;
This shows how important it is to have less salt. You will lose more salt!
