Bypassing the "high-end" trap High-priced salt nutritional value may not be high

, the market claims to have a particularly high nutritional value of high-grade salt variety, bamboo salt, well salt, sea salt, green salt, snow salt, rose salt ... It's dazzling. Is high-priced salt of high nutritional value? What are the nutritional differences between them? As ordinary consumers, how do we polish our eyes and make the right choice?surveya wide variety of salt products sold in thesalt is a must-have in people's kitchens. There are a variety of edible salts on the market today, with common well salts, slightly more expensive bamboo salts, and high-grade edible salts imported from abroad.it is understood that well salt is by drilling the way to extract underground brine made of salt, well salt presents a pure white.Reporters noted that the outer packaging of bamboo salt shows "choose three years of strong fresh bamboo, filled with high-quality sun salt, made of pine wood high temperature, not only to remove the sea salt heavy metals, pollution and other harmful substances to the human body, but also to retain all kinds of minerals in the sea salt, while the salt crystal into the essence of fresh bamboo and pine wood, increased the human body necessary a variety of trace elements." "After the reporter opened the package, the naked eye observed the bamboo salt appears gray-white particles, occasionally can see the black fine particles.the online business, rose salt is packaged as the "healthiest salt." Some businesses claim on the Internet: hundreds of millions of years ago in the Himalayas area was a vast ocean, Bohai Santian, solar energy dried the sea water produced crystalline sea salt, after hundreds of millions of years of geological extrusion and underground high temperature action, the underground minerals and sea salt combined to form a "salt fossil" - rose salt, and because of the composition of different minerals and produce red, pink, white different colors, shapes such as crystalline crystalline salt. "In addition to
84
trace elements, iron contains more calcium and lower sodium than regular salts, reducing the incidence of high blood pressure."prices of specialty products in addition to well salt, bamboo salt, rose salt, the reporter also found that the market recently appeared a lot of novel specialty salt products.lotte Mart supermarket, there are salts suitable for different cooking methods, including "boiled salt", "pickle salt" and "cold salt", and a bag of
320
grams costs around
4
. In addition, the supermarket also helps consumers strictly limit the amount of salt "low sodium quantitative salt" for sale, it is sprayed in the form of filling, each spray is
1
grams, the amount is easy to grasp. At the same time, mint-flavored "mouthwash salt" sells well. In addition, there are "fruit and vegetable washing salt" for sale.note that these emerging salt products and ordinary traditional salt prices vary greatly. At Lotte Mart, a bottle of
250
grams of low-sodium quantitative salt costs
8.5
yuan; a box of
90
mint The taste of mouthwash salt costs
12.6
yuan, and a bag of
400
grams of fruit and vegetable washing salt costs
7.8
yuan. Low sodium salts in ordinary plastic bags,
400
, sell for only
2.8
yuan.in
BHG
supermarket, the reporter also saw the price of imported salt. Sea salt from Mingmen, Japan, a pack of
500
grams sold for
55.7
yuan, also from Japan pepper salt, a bottle of
250
grams, priced at
40.90
yuan. And in the same supermarket, the price of domestic ordinary refined salt, a bag of
350
grams is only
2.2
yuan.Rose salt is not declared so "healthy"Recently, the media will be well salt, bamboo salt, rose salt
3
samples, sent to an authoritative testing body, to determine the content of sodium, magnesium, aluminum, silicon, sulfur, chlorine, potassium, calcium, iron and other elements.results published by the media showed that only
11,
elements could be detected in rose salt, a far cry from the
84
elements advertised by the business. Of
11
elements, only bromine and radon are not found in deep well salts and bamboo salts. But the two elements also contain very little in rose salt, one in 10,000 and four in 100,000, respectively. The magnesium and calcium content of rose salt is indeed higher than that of deep well salt and bamboo salt, but the sodium content is as high as
45.4%
. Not only is this higher than the common low-sodium salt, but it is also higher than the theoretical sodium content
39.36%
of the common salt, which shows that rose salt is not as "healthy" as it claims.Guangfeng, an expert at the China Food and Nutrition Information Exchange Center, said the
84
trace elements advertised by merchants were a logical trap. Modern food testing technology has developed to the present, as long as the test, almost all foods can detect
84
nutrients (trace elements). However, there are many kinds of nutrients, not necessarily more nutritious. To evaluate the nutrition of a food, in addition to looking at the variety, but also to see how much content of each nutrient, whether balanced. So it's not surprising that some rose salt merchants claim to have
84,
elements in their products, but this is a logical trap, and it doesn't mean rose salt is nutritious. Its most element is sodium chloride.some elements of rose salt are indeed higher than normal salts, he said. For example, the relatively high level of silicon in rose salts may have an effect on bone health, with
11.46
mg
of silicon in
6,
grams of salt per day. However, at present, whether silicon is a necessary element is controversial, China has not formulated the standard of silicon intake, whether it can play a benefit is uncertain. Elements such as iron in rose salt will also be higher, but only
6
grams of salt are recommended for one day, only about
2
mg of iron is available, compared with
20
mg of iron required by women in a day, and is not a major source of dietary iron supplementation."Even though some mineral elements in rose salt are higher than others, nutrition guidelines generally recommend eating no more than
6
grams of salt per day, which is very little of a supplement to minerals or other trace elements, and a balanced diet is the best way to obtain these trace elements. Yu Guangfeng said. The nutritional value of high-priced salt is not necessarily high according to Fan Zhihong, an associate professor at the School of Food Science and Nutritional Engineering at The Agricultural University of China, the nutritional value of food is not necessarily directly linked to the price. In fact, Fan Zhihong said, people do not need to rely solely on the consumption of rose salt to achieve the effect of calcium supplementation, because by contrast, green vegetables and brine tofu are good food to supplement magnesium and calcium. " is like some foods are relatively cheap, but the nutritional value is high; Food prices are determined by cost and supply and demand, high prices are not the reason why some salts necessarily have high nutritional value, rare and fried concept is the reason for its high cost. Fan Zhihong said. Also believes that the price of food is not directly related to its nutrition, and that high-priced salt is not necessarily of higher nutritional value. No matter what "luxury" salt, it is always salt, the main ingredient or sodium chloride, and the current study believes that excessive dietary sodium intake will increase the risk of cardiovascular diseases such as high blood pressure, can not let go of eating more. choose to see the sodium chloride content the market a wide variety of salt, price gap is also very large, as ordinary consumers, how do we polish our eyes, make the right choice? said that as a consumer first of all to clarify their physical health, a purposeful choice. Some people buy to control blood pressure, some buy for special flavors, and some just want to experience different products. It doesn't matter what you buy, but it's best not to be fooled into buying it, or to buy it blindly for health or nutritional purposes. Salt or salt, it is not appropriate to eat more, not to eat more confused. second, if it is to help control blood pressure and prevent cardiovascular disease, then when buying salt in the market, be sure to pay attention to see how much sodium chloride, you can choose low sodium salt. Low sodium salts are added to more than a quarter of potassium chloride, and some are added a small amount of magnesium chloride, which is
25%-30% lower than pure refined salts
For a variety of "nutritional" salts on the market, such as iron, zinc, calcium, selenium and other salt products, they do help to supplement the corresponding trace elements, but the actual effect is not necessarily good, and operability is not strong. Since 6 grams of
are
recommended daily, it is unlikely that nutrients will be supplemented by eating nutritional salts. If you really have problems such as iron deficiency, zinc deficiency, calcium deficiency, selenium deficiency, or should change by changing the total diet. In addition, Yan Guangfeng also stressed that some salts are said to contain trace amounts of silicon, boron, radon, lithium and other elements, but these elements have not been recognized as essential elements of the human body, from the salt supplement is beneficial, there is no medical conclusion, buy this "nutritional" salt is not much significance. Be careful of the invisible "Tibetan salt big household, a British survey showed that
300
packets of sliced bread,
28%
of the bread each contains more salt than a packet of original potato chips salt content. The news has left many consumers puzzled: Is sliced bread, which looks clean and tastes tasteless, high-salt food? in Yonghui's supermarket bread district, sliced bread takes up almost half of the shelves. Sales staff told reporters: "Sliced bread to go the fastest, when breakfast to eat more." A woman who picks bread also tells reporters that because sliced bread is easy to nutritious, she usually serves it as a breakfast staple and sometimes adds sausages, bacon or eggs to her children. When it comes to the inclusion of salt on the sliced side, the woman is surprised: "Does this bread have salt?" During visit, the reporter found that the sodium content of the original potato chips was
188mg/100g
. The sodium content of sliced bread on the market is more than
200mg/100g
, while the highest sodium content in sliced bread investigated by journalists is
592mg/100g
. Because sodium chloride (salt) accounts for nearly
40%
, sodium
1g
can be conversion to
2.5g
salt, so the sodium content on the nutrition label multiplied by
2.5
is the salt content. By analogy, three or four slices of bread alone account for almost a quarter of the
6g
recommended by the World Health Organization. Fan Zhihong said that bread production needs to put salt, in general, add
1%
, but also as high as
2%
. The formation of the opposite group of salt plays an important role in enhancing the elasticity of the surface and making the gluten texture dense. At the same time, salt can improve the color and organization of the bread, so that the color inside the bread white. In addition, salt is a substance with strong permeation pressure, which inhibits the development of yeast, so the fermentation speed can be regulated and controlled by increasing or decreasing the amount of salt. Huang Li, chief physician of Chinese and Western medicine combined with Chinese and Western medicine at the Sino-Japanese Friendship Hospital, said that in life, we must be alert to invisible salt, and that common "Tibetan salt households" include MSG, ketchup, soy sauce, sweet pasta sauce, soup, cheese, cake, bread, snacks, ice cream, French fries, hamburgers, pizza, instant noodles, sausages, chicken legs, lunch meat and so on. service there are eight harms to eating too much salt salt is a condiment that humans have used for thousands of years, and people have deep feelings for it. Some people say, what's so scary about salt? Why limit salt? In fact, eating too much salt is much more harmful to the body. 1.
increase edema. Water retention in the body is closely related to the amount of sodium consumed. Some women with poor blood circulation, although the heart and kidneys are not diseased, are prone to mild edema, especially in the days leading up to menstruation, which is more pronounced and looks swollen on their faces. Increased water retention due to hormone levels, coupled with a large intake of salt, can exacerbate bloating, swelling of the face, headache and other discomfort. 2.
hurt your throat. In people with chronic pharyngitis, food must be light. After eating foods high in salt, many people can clearly feel the increase in the mucus in their throats and their throats are not clear. Throat often inflamed, cough uncomfortable people, can not eat too salty, too hot, fried, smoked food, surface salt too much fried goods such as fried melon seeds, fried peanuts, salted various nuts, and potato chips and other salty snacks should be eaten less. 3. <br/
