Old Li is 68 years old, is a Sichuan native . He loves spicy food and has a salty taste.
at first, there was no discomfort in the body, but 2 years ago, it was found that 
hypertension . The doctor advised him to reduce salt and eat a light diet, but he did not eat spicy food for a day and felt uncomfortable all over, so he left the doctor's advice behind.
For a long time, he often feels thirsty and has a headache , and he doesn't care too much. Until a few days ago, I accidentally fell down slightly and broke my calf in .
Lao Li came to the hospital again and found that he had osteoporosis . The doctor said that Lao Li's blood pressure increased and osteoporosis were all related to high-salt diet .
As the saying goes, salt produces all kinds of flavors. Sodium is an important substance for the human nervous system to transmit information. Eating salt in moderation every day is beneficial to your health and is also very necessary.
However, due to different dietary habits, everyone's tastes are very different, but with the changes in lifestyle habits, more and more people prefer "heavy taste" , which means that many people may have excessive salt intake every day.
edible salt exceeds the standard, and the human body may experience symptoms such as thirst, frequent urination , edema , and may also cause a series of harm to various organs of the body.
High-salt diet is not advisable, so how to avoid the harm of excessive salt? You may consider changing the salt . Changing the salt may bring unexpected benefits.
1. Peking University research found that once the salt is changed, 450,000 less deaths per year!
University of New South Wales and Peking University jointly conducted a study. The study selected 600 villages in different regions of my country as a pilot project, and about 35 people were selected for one village.
followed up with more than 20,000 subjects for about 5 years. During the follow-up, the researchers found that using low sodium salts can reduce 0.32g of 24-hour urine sodium , increase 0.77g of 24-hour urinary potassium, reduce 2.65mmHg of systolic blood pressure , and the changes in diastolic blood pressure were not obvious.
After further analysis of the data on the prevalence of low sodium salts with chronic kidney disease , serum potassium and cardiovascular death, it was found that if low sodium salts are used nationwide, can reduce cardiovascular deaths by about 450,000 cardiovascular deaths by (including 208,000 stroke deaths and 175,000 ischemic heart disease deaths), which is equivalent to reducing all cardiovascular deaths by 10.9%.
At the same time, the use of low sodium salts is also expected to reduce 743,000 non-fatal cardiovascular events per year, reducing the incidence of chronic kidney disease by 6.9%.
Peking University Clinical Research Institute New research led by Professor Wu Yangfeng shows that if residents replace their ordinary salt with low sodium salt, the country will reduce deaths by more than 10%. The total population counted in my country in 2020 was 1.412 billion, with a mortality rate of about 7.07%. If it is roughly estimated, it will reduce the deaths of html by about 11 million per year.
2. What is the strength of low sodium salt compared to ordinary salt?
low sodium salt is so good? What is the difference between it and ordinary salt? Follow Xiao Miao to learn more about this issue.
Dalian Central Hospital Wang Xingguo pointed out that , the sodium content in the low-sodium salt is reduced by about 30% compared to ordinary salts, but the content of potassium is about 100 times higher. While reducing sodium intake, it can also help the body replenish potassium. In addition, low sodium intake is also helpful to reduce the risk of hypertension and cardiovascular diseases.
For people suffering from hypertension, it can also help maintain the sodium and potassium balance in the body, and can play an auxiliary role in controlling blood pressure.
Although there are many benefits of low sodium salt, it cannot be eaten in large quantities in daily life, and it is also important to control the amount.
Under normal circumstances, the amount of sodium that adults need every day is 2200mg. The sodium ingredient that can be consumed from food is about 1000mg, which means that we still need about 1200mg of sodium and about 3g of salt in a day.
Chinese Nutrition Society recommends that the daily salt intake of Chinese residents should be kept below 6g, and even if they eat low sodium salt, they should try to maintain it under this standard.
3. Although low sodium salt is good, it is not suitable for people of three groups to eat
. Since low sodium salt is so good, why are there rumors that eating low sodium salt will cause hyperkalemia ? Is "life-sending salt" ?
Although the benefits of low sodium salt are many, the following groups are not suitable for consuming low sodium salt.
Popular people taking antihypertensive drugs: High blood pressure patients who are taking Priligy, sartan and insufficiency diuretics should be cautious when using low-sodium salts, because the drug will inhibit the performance of aldosterone, , which can easily cause abnormal metabolism of potassium ion , which in turn induces hyperkalemia.
Popular populations taking immunosuppressant : Common ones include cyclosporine and tacrolimus drugs. These two drugs will also affect the synthesis of aldosterone in the body, which in turn causes potassium to be unable to metabolize and excrete, which can easily induce hyperkalemia.
Renal insufficiency: Low sodium salt contains a higher content of potassium, and potassium ions need to be excreted from the body through the kidneys. For people with poor kidney function, eating low sodium salt will increase the burden on the kidneys, which is not good for health.
4. Keep in mind 3 points for national salt control and start a lifestyle of reducing salt
Salt is one of the indispensable nutrients in our body, but we cannot consume too much in daily life. How to remove salt limiting?
First, you can buy salt-limited spoon . This can make you add about the amount you add when cooking, which is helpful for controlling the addition of salt;
Secondly, in addition to salt, beware of some salt in some other ingredients, such as soy sauce, chicken essence, and oyster sauce , etc. When using these condiments, you should appropriately reduce the addition of salt; when purchasing packaged food, pay attention to Nutritional ingredients list , and choose products with low sodium content.
Finally, try to choose fresh foods when choosing daily foods. Try to eat less pickled pickles, processed meat, canned foods, etc. . The salt content in these foods is not low. Eating them in large quantities can easily lead to excessive salt content.
Salt limit is something that all Chinese people need to pay attention to. It is recommended that everyone adhere to the good habit of a light diet and try to eat less foods with high salt content. Low sodium salt is also a good choice for salt control. What kind of salt do you use at home?
