Salt, with the reputation of "the best taste", is one of the essential condiments in our daily cooking. It can not only increase the salty and umami taste of dishes, but also promote the formation of other flavors. It can be said that no matter what the taste is, its original flavor can only be reflected in the background of salt. No wonder people often make fun of it.

Salt originated in China. It is inferred that during the period between Emperor Yan and Huangdi, people began to make salt from seawater. In the 1950s, cookware was found in a batch of cultural relics unearthed in Fujian. It can also be speculated that in the Neolithic Age, people have learned to cook sea salt.

Nowadays, salt has long been a well-known seasoning, and everyone knows it. But now there are more and more varieties of salt, which makes it difficult for many friends to buy salt. Today, Lazy Meow will talk to you about the most common salt. Let's see:

What is the difference between "low sodium salt" and ordinary salt?

The composition of 0 1 is different. As we all know, the main component of salt is sodium chloride, and it is the sodium ion in it that provides the salty taste. The common salt we usually buy and eat in supermarkets is mostly iodized salt. Low sodium salt, as its name implies, is a salt with lower sodium ion content than ordinary salt.

At present, most of the low-sodium salt sold in the market takes table salt (iodized salt) as raw material, and a certain amount of potassium chloride (usually about 30%) is added to it to increase the potassium ion content and reduce the sodium ion content, so as to achieve the purpose of "reducing sodium". We can also simply understand that low sodium salt refers to adding potassium chloride to common salt.

In terms of composition, the main component of common salt is sodium chloride, and potassium chloride is added to low-sodium salt, thus reducing the content of sodium ions in the component.

Compared with common salt, low-sodium salt has two remarkable characteristics, namely, "reducing salt without reducing salt" and "maintaining the balance of sodium and potassium".

Now advocating "low salt diet" and "reducing salt intake" means controlling sodium ion intake. Excessive intake of salt means excessive intake of sodium ions, and high concentration of sodium ions will accumulate in the body, which will bring various adverse effects to the human body. Potassium ions in low sodium salt can also provide salty taste, and the salty taste is not affected while reducing sodium.

According to the data provided by the Reference Intake of Dietary Nutrients for China Residents, every healthy person should consume 2,000 mg of potassium every day. By adding potassium ions to salt, sodium can be reduced and potassium can be supplemented, which can be said to kill two birds with one stone and maintain the balance of sodium and potassium to a certain extent.

In terms of characteristics, low-sodium salt has two characteristics that ordinary salt does not have, namely, "reducing salt without reducing salt" and "maintaining the balance of sodium and potassium".

Compared with common salt, low-sodium salt is more suitable for middle-aged and elderly people, "three high people" and pregnant women to reduce their daily sodium intake and avoid various diseases caused by excessive sodium intake.

However, the following people are not suitable for eating low-sodium salt, or they can only eat it with the consent of a doctor. They are high-potassium drug users, people with hyperkalemia, heart disease or kidney problems, because some potassium is added to low-sodium salt, which is not very friendly to these people.

From the point of view of suitable population, low sodium salt is more suitable for middle-aged and elderly people, but not for patients with hyperkalemia and heart disease.

Buy salt, choose low sodium salt or ordinary salt? After understanding the difference between low sodium salt and common salt, I believe everyone is more concerned about which salt to choose.

For most healthy people, low sodium salt is a better choice if it is not suitable for potassium intake. Because in the case of the same use of salt, it can not only reduce the intake of sodium, but also supplement potassium.
