The state administration of food and drug administration has released a complete list of official "carcinogens" to provide guidance and control. The list of carcinogens is divided into one to four categories. In addition to the recent buzz of aristolochic acid, China's salted fish are once again in a list of carcinogens Dream beauty pro hard sell.
Interpretation of the
The four major categories of carcinogens
One category (definitely carcinogenic) : there is sufficient evidence to prove that the human body causes cancer.
Type ii A (which is more likely to cause cancer) : limited evidence of human carcinogenicity and sufficient evidence of carcinogenicity of experimental animals Dream beauty pro.
Type ii B (which is less likely to cause cancer) : the evidence of human carcinogenicity is limited, and the evidence of carcinogenicity of experimental animals is not sufficient; Or the human carcinogenic evidence is insufficient, the experimental animal carcinogenic evidence is sufficient.
Three categories (whether it is unclear whether it is carcinogenic) : suspicious of human carcinogenicity, inadequate human or animal data.
Four types (basic non-carcinogenic) : substances that may not be carcinogenic to the human body and lack of sufficient evidence to support its carcinogenic substance. This classification currently includes only one substance, caprolactam.
Salt fish salted or the cause of nasopharyngeal carcinoma
In particular, the term "positive carcinogen" refers to the fact that it is possible to confirm that it contains cancer-causing substances, rather than eating it, and that it is only a risk of cancer.
Look at the more depressed, the salty fish is the common home food that is common at the table how to cause cancer? In fact, Chinese salted fish is not the first to make the list, and as early as 2012 it has been identified as a type of carcinogen. After the oncogenic list was released, netizens joked, "the salted fish won't turn around anymore."
Guangzhou jing-hua xie, director of the first people's hospital otolaryngology is introduced, the factors of nasopharyngeal carcinoma (NPC) is not yet entirely clear, it can with EB virus infection, eat salted food and living in polluted air environment and so on Dream beauty pro.
Guangzhou city first people's hospital of doctor of vice director of otolaryngology head and neck surgery He Long said, can happen at any age, nasopharyngeal carcinoma (NPC) for good hair age 30 to 50 years old, male incidence is 2 to 10 times that of women.
In particular, many people like to eat salted fish, salted vegetables and other pickled foods, which contain nitrite, which is rich in preservatives such as salted fish, salted eggs and salted vegetables, which are closely related to the incidence of nasopharyngeal cancer.
Special note
Don't think that as long as it's a class of carcinogens, the grading of carcinogens is just a matter of whether the cancer evidence is sufficient, rather than the ability to see it leading to cancer. The three types of carcinogens are evidence that the evidence for both animal and human carcinogenesis is ambiguous. In fact, the likelihood of cancer is very small.
Main representative:
Sudan red, printing ink, hypochlorite, mercury and organic mercury compounds, polypropylene, polyethylene, PVC, glass fiber, tea, tea is alkaline, saccharin, static magnetic field, vitamin K, cholesterol, destroy the long grass, etc Dream beauty pro.
Experts suggest that
Some carcinogens should be avoided as far as possible, such as tobacco and alcohol cancer; Some carcinogens have to weigh the pros and cons and know that X is a carcinogen, but you have to take a picture of it. Some of the carcinogens need to be controlled, such as barbecues, which are fine if not long term.
