Today, there are more and more salt types on ordinary supermarket shelves

The price ranges from one yuan to tens of yuan

And the type of salt on the e -commerce platform is richer

There is even a sky -high price of 4500 yuan per 100 grams of salt

These salt, the price is so much difference

Is the actual function really different?

Reporters visited some supermarkets in Nanjing and found out

Most of the salt displayed on the shelves

The capacity is basically around 400 grams

There are also a small amount of bamboo salt and imported salt, the price is slightly higher

However, open the e -commerce platform

Both color or origin as the selling point

The price is also staggering

Ordinary salt in the supermarket in the supermarket

It's six or seven hundred times tall

A brand Mediterranean salt

It is called formed by the pure and non -polluting Mediterranean Sea

A variety of natural basic minerals that are rich in humans

In the introduction of multiple high -priced salt products

There are propaganda words such as natural, healthy and rich minerals

Doctor said

The purity of sodium chloride in ordinary salt is basically above 97%

Other ingredients can be ignored

There is no health value

Jin Hui, chief physician of the clinical nutrition department affiliated to Southeast University, said that in the Chinese dietary guidelines, all normal people should not eat more than 5 grams per day. Essence And this difference between different salt does not have much scientific significance. If it is for minerals other than salt, the intake of salt will increase, increasing the risk of hypertension, and kidney damage. And the probability of some tumors also increases.

Doctor's suggestion

If consumers like the taste and taste of a certain salt

Can be purchased on demand

But if you are healthy as the standard

Except for some sick people

Ordinary salt in the supermarket can be satisfied

Dr. Jin said that in fact, according to the nutritional component table, the most important thing is three types, and the three types of sodium, iodine, and potassium are enough. Those with high blood pressure can be used with low sodium, such as potassium chloride instead of sodium chloride. So in the final analysis, when you buy salt, you just need to pay attention to sodium content and iodine content.

Salt is just condiments, not health products, and does not need to pay attention to too much ingredients. From the perspective of health, there is not much difference in high prices and low prices. Everyone should pay more attention to the total intake. Do not exceed 5 grams per day.
