[Cai Zhi Toutiao] Is the price of ordinary salt 56 times. Is "net red salt" a IQ tax?

The price of a bag of 400 grams of edible salt is around 3 yuan, but recently on the Internet, various "net red" imported salt broke people's awareness of salt, Himalayan powder salt, Persian blue salt, Hawaii black salt in the United States, France, France, France Flowers of gray salt, salt ... In addition to exquisite packaging and variety, the prices of these salt are more expensive. For example, a bottle of 425 grams of Hawaii black salt is priced at 169 yuan, which is more than 50 times more expensive than ordinary bags.

"Everbright salt"

These net red salts are often labeled on a specific place of origin.

On the e -commerce platform, a product called "Hawaii Volcanic Rock Salt" wrote in the propaganda copy that the product is refined from the lava layer and the mountains. Seasoning necessities. Merchants marked that in addition to cooking, this salt can also be used for skin frosted and decorative.

Another Himalayan salt that claims to be "King of Salt". For details, it is introduced that it is more than 10 times that of the trace elements and minerals. "The remaining seawater is hidden in about 600 meters underground. After millions of years of squeezing and high temperature, the minerals in the ground are combined with the combination of sea salt in the ancient sea bed. This is the Himalayan sea salt." Pollution, rich in minerals required by the human body, can be eaten by the whole family. "

SPS Salt Flower is based on "legendary ingredients, salt treasure" as a propaganda. The merchant said that SPS salt flowers have strict requirements on the growth environment. Only in the summer with sufficient sunlight and sea breeze, can the surface of salt water form a thin snowflake salt, so 100 square meters can only produce 1kg. It is also favored by the royal family. Of course, its price also came to 1.18 yuan per gram, which was nearly 160 times the ordinary salt.

Some netizens commented that these magnificent salt is sprinkled on food, which is pleasing to the eye; some netizens said that buying such a expensive "net red salt" is purely a waste of money and IQ tax.

Compared with ordinary salt, is there really only color differences?

"Net Red Salt" is different in color

Whether it is the Himalayan rose salt, the black salt of Hawaii, and the Persian blue salt in the United States, the "selling points" are mainly natural, origin, and special minerals containing special minerals. Are these "expensive" salt more nutritious? Is it safer to eat?

Zhong Kai, the director of the Kexin Food and Health Information Exchange Center, said that the merchant claims that "Himalayan powder salt contains more than 98%of sodium chloride, and the rest include iron, calcium, magnesium, potassium, zinc, silicon, copper, etc. Material is the king of salt. " The translation means that the salt with a purity of 98%, the remaining 2%is more than 80 impurities.

It is said that its calcium, magnesium, potassium and other elements have more content than ordinary salt, so nutrition is more balanced. But there are many elements except sodium, isn't it impurities? With the same logic, isn't it nutritious than fine salt made of seawater? In fact, the trace elements in the salt can be ignored (the added enhancer agent added to the additional agent Except), after all, salt intake is too low every day.

In short, whether it is ordinary salt or net red salt, its main ingredients are sodium, iodine and other elements, and the core functions are seasoning. Ordinary edible salt also comes from the natural world. Its ingredients and nutritional value are almost the same as net red salt. Even if some net red salt contains some trace elements, the content is extremely low, and it can be ignored. Such as arsenic and uranium, if the content is large, it is harmful to human health.

Jeff McGrath, a clinical nutritionist at the Vegee Medical Center at New York University Hospital, has said that it is difficult to confirm that the Himalayan rose salt is more natural or more pure than ordinary salt. In fact, the Himalayas' rose salt may contain an almost impossible element. If it is separated and large -dose to eat these elements, such as arsenic and uranium, it will be harmful. "In the current food world "".

Not reliable by eating salt and replenishing minerals

According to information, there are three main types of edible salt in my country: sea salt, lake salt, and mineral salt. Sea salt is formed after the introduction of sea water into salt fields; lake salt is where there is a salt lake, and the brine in the salt lake is made in the salt field; It is 100 meters to 3000 meters underground.

The sources of salt are different, and there is no big difference in nutritional ingredients and values. For the use of nutritional enhancers for edible salt, there are strict management standards and limited scope in my country. According to the "Food Nutritional Repertoic Incunctors" revised by the Ministry of Health, salt must not add nutritional enhanced agents except iodine. , Iodine, potassium "three types.

This means that other so -called "minerals" elements are not within the scope of the "nutritional composition table", and they are not allowed to be added to salt. In other words, salt is just a condiment. It is not a health product or nutritional product. It is basically unreliable to supplement the "nutritional element" through salt that has restricted intake. Salt is just a condiment, not a health product, and does not need to pay attention to too much ingredients. It is enough to look at the two items of sodium and iodine.

Most of the minerals can also be completed through daily diet.For example, calcium -containing foods mainly include milk, soybean products, kelp, seaweed, shells, oysters, sardines, shrimp, etc. The food containing is mainly animal blood, egg yolk, pork liver, soybeans, sesame, black fungus, red dates, etc.EssenceFoods rich in iodine include kelp, seaweed, hair vegetables, seafood, spinach, Chinese cabbage, corn, etc.(WeChat public account "Caizhi Headline" comprehensive from: Beijing Youth Daily, Surging News, Upstream News, etc.)
