“Sour, sweet, bitter, spicy, salty”, the five flavors of life, are the foundation of people’s food making, but to say which flavor is the most important, it is probably not salty Yes, a pinch of salt can make food delicious.
However, in the eyes of modern people, salt is a controversial condiment, and with the advancement of medical technology, people understand How much salt you eat can affect your health.
Sodium chloride in table salt is the main way for the human body to supplement sodium, but once the level of sodium in the human body changes beyond a certain range , it also brings side effects, which means that people can’t refuse salt intake, but they can’t eat salt without scruples.
In order to grasp the intake of sodium, people have adjusted the salt many times, from the previous high sodium salt to iodized salt, And then to low-sodium, which arguably should be loved, but there is still some debate about low-sodium.
Low sodium, good or bad?
1. Is low sodium salt equal to “death salt”?
As we all know, the main ingredient of table salt is sodium chloride. In the early years, in order to improve the iodine deficiency common among Chinese residents, people added iodine to table salt, which is called iodine. It is iodized salt, and low-sodium salt is improved on this basis.
Low sodium salt is not sodium free, but iodized salt with 10-30% less sodium content, potassium chloride and magnesium sulfate are added instead, so that the three elements of sodium, potassium and magnesium needed by the human body can be supplemented in a balanced manner.
From the perspective of the composition ratio of low sodium salt, it is more beneficial for hypertensive patients because< strong>High sodium is a risk factor for hypertension, and reducing sodium content indirectly protects blood vessels and reduces cardiovascular risk.
“British Medical Journal” also proposed that if China fully adopts low sodium salt, 450,000 cardiovascular disease patients can be reduced every year, but renal function People who are not complete may not be suitable for eating low-sodium salt.
· For people with kidney problems, low sodium is the salt of death
The human kidneys can regulate the levels of sodium and potassium, and most people with renal insufficiency are caused by kidney damage, which will cause the kidneys to adjust the levels of sodium and potassium. Insufficient regulation, potassium excretion function is limited.
Eating low-sodium salt at this time will increase the content of potassium, resulting in the phenomenon of hyperkalemia in the body, which is easy to cause hyperkalemia and electrolytes. Disorders are more dangerous, so people with low renal function should not eat low-sodium salts.
· What are the benefits of low sodium for other populations?
The New England Journal of Medicine published a study led by the team of Professor Wu Yangfeng from the Peking University Clinical Research Institute. The study included 600 villages selected from 10 counties in 5 provinces in China, with a total of 21,000 patients over 60 years old with hypertension or stroke.
Researchers randomly divided them into a control group eating ordinary salt and an experimental group eating low-sodium salt. The results confirmed that eating low-sodium salt A group of heart disease, stroke and all-cause mortality decreased significantly across the board.
It can be seen that consumption of low sodium salts can reduce the risk of cardiovascular disease, and it is safe for ordinary people to Saying it is safe and reliable is better for your health.
2. Although low sodium has many benefits, it is not for everyone
It is true that low-sodium salt has many benefits to the human body, but everything has two sides, and there is no one food that is suitable for everyone. The same is true of low-sodium salt, which is not suitable for everyone.
Potassium chloride is added to low sodium salts, which is a way to supplement potassium for the general population, but Patients with nephropathy, hyperkalemia and people taking drugs that inhibit potassium excretion are not suitable to eat low sodium salts, otherwise it will lead to excessive potassium content in the body, resulting in serious consequences.
Additionally,heavy labor workers, heat workers, and those following strenuous exerciseYou should also be careful about eating low-sodium salts. Although low-sodium salt reduces sodium content, you should also pay attention to controlling your intake every day.
< p data-track="22">In addition to the above-mentioned contraindications to avoid eating, the general population and hypertensive patients can use low-sodium salt instead of ordinary salt, but also pay attention to control the consumption. p>
In particular, the total daily intake of sodium should be considered, and the invisible salt in foods such as doubanjiang and soy sauce should not be ignored. For details, please refer to the “Dietary Guidelines for Chinese Residents” Medium: Adults consume 6 grams of salt per day.
3. Excessive sodium is not harmful. How to reduce the harm of high-sodium foods to us?
Excess sodium is harmful to the human body. This is already a The consensus of the contemporary people is that high-salt foods are also included in the forbidden area in many medical and dietary guidelines, and this may be a way to get out of the shadow of high-sodium foods.
The human blood vessel is like a sponge. Because of its permeability, once the sodium ions in the human body exceed the standard, water and sodium retention will occur due to excessive water absorption, which will cause pressure on the blood vessels, which will be induced after a long time. High blood pressure. In addition, high-salt foods are also associated with obesity, diabetes, stomach cancer, bowel cancer, and osteoporosis.
Want To reduce the harm caused by high-sodium foods, we must first reduce the intake of salt, reduce the intake of salt-containing seasonings, and reduce the intake of high-salt foods from the root source .
SecondaryEnsure potassium and antioxidant intake , through them to promote the excretion of sodium ions, to achieve the purpose of regulating the level of sodium ions. At the end of the meal, pay attention to choosing low-salt foods, necessary Rinse the salt off the surface of the food with water from time to time.
Salt is Chinese In the inherent impression of people, the presence of salt is indispensable for making delicious dishes, but in order to protect health, people must also establish a correct diet concept, learn to choose better seasoning options, and try to use low sodium. Salt can fundamentally prevent cardiovascular disease and lay a solid foundation for health.
Remind everyone again: Do not ignore the dangers of high-salt foods, whether high-sodium or low-sodium, high-risk groups please keep your mouth shut, It should be noted that disease enters from the mouth, and do not cause physical damage due to temporary appetite. #health star Program# #Health2022#
