"soy sauce" is a network popular language that ridicules "nothing to do, pure way through". But now that you can't get out of the sauce, you have to ask:
from the middle of this month, the Ji'nan supermarkets sell iron soy sauce - a new type of iron fortifier EDTA sodium iron in soy sauce to prevent iron deficiency anemia. However, it has been reported that the higher the iron content in the blood is, the higher the possibility of cancer.
in fact, these intensification condiments are increasingly being questioned from iodized salt, nutrients to the iron sauce.
event
iron sauce will cause cancer?
yesterday, a news on the Internet aroused the attention of Wei people in Ji'nan.
the report said a few days ago, the China CDC food strengthening office started the two phase of the "iron fortified soy sauce" project, allowing more cities to buy iron fortified soy sauce. It includes Shandong province.
Bao Shanfen, a researcher in the microelement Research Department of the Nutrition Department of the PLA General Hospital, said that EDTA could lead to a lack of trace elements in the body. In addition, the higher the iron content in the blood, the higher the possibility of cancer. "Just heard that iodized salt may cause excessive iodine, and iron sauce has come out again. Does soy sauce usually strengthen soy sauce? Is it harmful to the body? "Ms. Wei then asked through the consultation hotline of provincial disease control.
survey
stainless steel sauce in the supermarket is not much
"what? Ferric soy sauce? I never heard of it." Yesterday morning, a lady who was shopping at WAL-MART supermarket said that she only knew soy sauce had soy sauce and old soy sauce, and did not know that there was "iron soy sauce".
reporters saw that four or five meters long seasoning shelves were full of steamed fish sauce, organic soy sauce, seafood soy sauce and so on. Among these dozens of brands, finding iron fortified soy sauce is not easy.
after careful search, the reporter finally found two iron fortified soy sauce, which are the iron fortified straw mushrooms and the iron fortified soy sauce of the Xinhe brand, respectively. In addition to the labels, there is a substance in the ingredient list of soy sauce called sodium ethylenediamine tetra acetate. "Is there any difference between the taste of iron soy sauce and the ordinary soy sauce?" for the reporter's question, the salesman could not answer, "this kind of iron soy sauce is just listed, and I don't know much about it myself."
What about the price of iron soy sauce? The reporter learned from a staff member of the supermarket in Ginza that the price of "iron soy sauce" is not very popular, with the example of Xinhe iron fortified soy sauce, a bottle of 500 milliliters, and the price is 11.8 yuan, twice as expensive as the ordinary Xinhe sauce.
about sales, a supermarket salesman said, "we don't know much about iron fortified soy sauce, and the price is also a little high, and we buy less. However, sales have been showing signs of improvement in recent years.
explain
the Shandong female anemia is very serious
so, is it necessary for the Jinan to make up the iron? With the concern of the citizens, the reporter interviewed Bi Zhenwang, the director of the provincial disease control and health care institute. He said that starting from October 10th this year, Shandong Province, as the second batch of pilot provinces, began to promote the pilot work of iron fortified soy sauce. The purpose of strengthening iron in soy sauce is to reduce the incidence of anemia.
in fact, anemia in Shandong is still serious. In particular, women, up to 28%. Bi Zhenwang said that urban women generally pay attention to body shape and control meat intake, mainly vegetables. This diet structure may be one of the causes of anemia.
for the women of childbearing age, this iron deficiency and iron deficiency anemia can cause fetal dysplasia and low birth weight infants. It also affects children's intelligence and physical development.
he explained that in Shandong, for example, although the content of iron in food is also good, most of them are vegetative. Such iron elements are hard to be used by the human body, and only about 1% of the iron elements can be absorbed.
in order to alleviate the anemia of residents, especially women, the state has launched the promotion of iron soy sauce.
response to
that dose not affect the body
, of course, the focus of the public is that if iron is not needed, will the healthy people eat iron soy sauce and hurt the body? Is there any reason for Bao Shanfen's theory of excessive carcinogenesis?
reporter yesterday contacted China disease prevention and control Sun Jing, deputy director of the system center. She is responsible for the Shandong iron fortified soy sauce promotion and application project. She said that because the daily consumption of soy sauce is limited, the iron fortifier added in soy sauce is also trace, and the amount of iron filling is generally not very large, and it will not produce excessive iron.
the excess iron will be stored in the human body even if it is overtaken for a moment, and too many words will be discharged through the normal regulation of the human body and will not produce accumulation. In addition, no studies have confirmed that the increase of iron intake will affect the absorption of calcium and zinc.
, so, for some experts on the Internet concerned about iron soy sauce, Sun Jing believes that these concerns are understandable, but the lack of data and experimental support is not scientific. "However, if it is not anemic, there is no need to eat fortified iron sauce."
the real iron deficiency is only a part of the crowd. For example, people with insufficient iron intake such as poor teeth, less eating, less iron intake, excessive iron loss, such as women's excessive menstruation, and the large demand for iron, such as children, pregnancy or lactating women. These people should make up more iron. In addition, some patients with iron excess or iron deposition are not recommended.
Meng Jianzhong, director of Department of Hematology, General Hospital of Jinan Military Area, said that once these people took iron soy sauce, they could cause the deposition of ferritin on the viscera, affecting the function of the organs.
there are experts on the Internet that now add sodium iron EDTA as raw material to soy sauce and flour to "improve the nutritional health of Chinese people", which is called "fortified food". Such a lack of close supervision is dangerous, which may cause consumers Tie Yuansu to overeat, leading to chronic poisoning.
, Chen Liyong, deputy director of the quality control center of Shandong Province, said that the addition of EDTA may have a certain effect on health in the long run, although each bottle of soy sauce or the quantity of each meal is not large, but the effect of the flavoring is chronic and chronic. At present, the domestic research on the impact of EDTA and human health is missing. He suggested that the state should organize relevant departments and work out the guiding standards for the strengthening of soy sauce and health while carrying out the iron strengthening projects.
