Do you really know these five kinds of salt? The choice of edible salt needs to consider its own needs.

This is an era of fear of "salt". WHO recommends that everyone should consume 5 grams of salt every day. A large number of media constantly report the necessity of low-salt diet, which shows the consequences of excessive sodium intake.

Anyone who knows something about Japanese living habits can't help wondering: Why is Japan, whose salt habit is twice as high as the standard, the longest-lived country in the world?

In fact, just reducing salt will not make you healthier. In fact, if you don't eat enough salt, your body will not be able to retain water. More importantly, find the "salt balance" of your body! Lamian Noodles, for example, is very salty.

Although the salty taste is the same, there is a so-called "healthy salt", that is, the salt that reduces the "sodium" content. Look at its ingredients carefully, reduce sodium chloride and increase potassium chloride!

But excessive potassium is more dangerous than sodium! Sodium will absorb water and raise blood pressure, while potassium will excrete sodium through urine and lower blood pressure. So which is better? Please look down.

Many people know that patients with hypertension should eat fruits or vegetables containing a lot of potassium, but if potassium is excessive, it may cause muscle paralysis, chest pain, arrhythmia or dyspnea.

However, in the United States, Australia and other developed countries or regions, products such as low sodium salt will be marked with side effects, and the Health Bureau will also mark a reminder of "beware of health side effects".

Salt with high potassium chloride content has health risks. But if we only look at the unilateral influence of sodium in salt, it may produce unexpected results. So this problem is complicated.

In fact, everything has its medicinal properties and toxicity, so whether it is sodium or potassium, if analyzed separately, it can be an "angel" or a "devil" according to different viewpoints.

We need salt and sodium chloride. It is impossible to always ignore the role of salt or even replace it with other substances, because only sodium chloride containing chlorine and sodium can play a role. Salt is an important part of digestive system and electrolyte, and also an important component of cells and tissues.

Replacing sodium with other substances or reducing the intake seems healthy, but from the physical point of view, it is not, because salt is a necessity for survival, and the body will supplement the required amount by all means, and eventually it will cause excessive intake because of other things.

There are many kinds of salt in the market. Which one should I choose? In fact, it will be very confusing. There are natural pure salts that emphasize natural manufacture, and functional salts of foods or extracts that add other substances, which will produce salty taste.

But there are actually some differences in eating, and their uses and effects are slightly different. The biggest reason why we eat salt is to reflect the "salty" taste, not for other tastes, so in order to bring out the taste of food completely, we need pure salty taste.

According to different processing methods, salt can be divided into different types. Here I mainly introduce: sun-dried salt, refined salt, rock salt, refined salt, bamboo salt and so on. I won't introduce iodized salt here, because it is a refined salt, and it is relatively easy to buy in our life.

1, sun-dried salt

From its name, we can know that it is salt produced by enclosing seawater into a salt field and evaporating water by wind and sunlight through natural methods. After crystallization, it is hexahedron with coarse particles. We commonly call it "coarse salt", which contains bitterness when exposed to the sun.

2. refined salt

Our most common salt, iodized salt and non-iodized salt, is one of them. It uses purified seawater to pass through ion exchange membrane, only sodium chloride can pass through it, and the salt is produced by high temperature steam in vacuum evaporation tube.

In this production process, other impurities will be filtered out, and other minerals and impurities except sodium chloride will be purified. The salinity is general and it is safe salt.

3. Rock salt

It was formed by evaporation of seawater millions of years ago, and it was mined like a coal mine, or salty soil was dissolved in water and then extracted.

About 70% of the salt produced in the world is one of the most common salt species. The environment varies from place to place. There are usually three colors: white, green and red, and the quality varies greatly in different regions.

4. Lake salt

It is a salt lake produced by long-term crustal changes, and after a long period of water evaporation, the salt is left in the lake water to produce salt products.

Lake salt is also a salt that is naturally dried and crystallized by sunlight, and is processed and sold for the second time. Among them, the Inca salt in Qinghai, Shanxi and abroad is very famous.

5. Bamboo salt

The production process of bamboo salt is complicated, which is made by putting the sun-dried salt into bamboo, sealing it with loess and baking it at a high temperature above 800℃.

Especially, the bamboo salt baked for 9 times was melted at a high temperature exceeding 1300℃ in the last baking process. High temperature baking will evaporate impurities and maximize its purity.

In this production process, other impurities are removed, and the components of loess and bamboo are also integrated, which is not only salty, but also retains the taste and aroma of bamboo.

Sun salt VS refined salt

People who choose sun-dried salt because of traditional ideas emphasize that sun-dried salt is pure natural salt, while refined salt is synthetic chemical salt, which is harmful to health. And subjectively, sun-dried salt is a kind of natural salt, which contains many beneficial minerals and is very good for the body, but refined salt is only a chemical substance, sodium chloride, which will cause harm to the body. The conclusion is that refined salt will threaten people's health and must not be eaten. There are also those who support bamboo salt, which are also similar reasons.

Is that so? In fact, refined salt is not artificially synthesized, but removes excess impurities through scientific means. Beneficial minerals and trace elements can be obtained from other ingredients, and no additional salt is needed. Sodium chloride is a useful element for our body to point to salt.

Drinking water is not the only way to get nutrition. Water and salt are not the whole of our body, they just help digestion, synthesis, regulation and transportation of nutrition, and play an important supporting role in this "drama" of digestion.

?

So what kind of salt do you choose? It varies from person to person in the process of complex chemical workshop operation. However, in the end, the type and intake of salt are selected. It depends on factors such as different regions and different personal constitutions. We can't generalize. The most expensive natural or synthetic salt must be the best. what do you think?
