4 kinds of food have the risk of cancer, but many people eat every day! To stay away from cancer, you have to take the table off

Recently, the World Health Organization's International Agency for Research on Cancer (IARC) released the latest global cancer burden data for 2020: 19.29 million new cancer cases and 9.96 million deaths worldwide in 2020.
, 4.57 million new cancer cases and 3 million cancer deaths in China in 2020, with the number of new cancers and cancer deaths among the highest in the world.
in the face of such severe cancer morbidity and mortality, it is particularly important to prevent cancer and stay away from substances that are at risk of cancer.
as the saying goes, "sick from the mouth", these foods with a risk of cancer are likely to appear on your table.
is a carcinogen? Before looking at carcinogenic foods, let's find out what carcinogens are. Do you get cancer if you eat carcinogens? In general, carcinogens are substances that cause an increase in malignancies, including chemicals, physical substances, life and work styles that increase the risk of cancer.
Depending on the circumstances, WHO classes them into four categories: class 1 carcinogens: such carcinogens are those that have sufficient evidence to be carcinogenic to humans, and carcinogens are shown in experimental animals, such as alcohol, aflatoxin, etc., which can be classified as carcinogens.
2A carcinogens: There is limited evidence of cancer in humans, but there is sufficient evidence of carcinogenicity in experimental animals, as well as strong evidence that such substances are carcinogenic.
, class 2A carcinogens have been found to have carcinogenic properties in animal experiments, which in theory can also cause carcinogenic threat to humans, but experimental evidence is limited.
2B carcinogens: such substances may cause cancer in humans, consistent with the following three conditions: first, there is strong evidence that they are carcinogenic when exposed to both human cells and humans; class
3 carcinogens: when animal experiments and human carcinogenic evidence is insufficient, it belongs to the three types of carcinogens, these substances in human carcinogens can not be classified for the time being, for animal experiments there is evidence of carcinogenic mechanisms, but this mechanism in humans do not work in the substances, also belong to the three types of carcinogens.
life, carcinogens are everywhere, some carcinogens are around us.
Away from 4 kinds of food tobacco with carcinogenic risk: whether smoking or second-hand smoke, will increase the risk of cancer, Chongqing Cancer Hospital Wang Zhiqiang pointed out that cigarettes in the process of burning, will form more than 4000 kinds of chemicals, including tar, nicotine, nitric oxide and other substances are very harmful to the human body, especially tar is very carcinogenic, not only will induce lung cancer, but also lead to nasopharyngeal cancer, esophageal cancer and other cancer incidence rate increased.
: Acetaldehyde in alcohol is a class 1 carcinogen, with one in 30 cancer deaths reported to be caused by alcohol.
2014 World Cancer Report made it clear that 3.5 percent of cancers were alcohol-related, including oral, esophageal, liver and colon cancers.
, staying away from alcohol can effectively reduce the risk of cancer.
moldy food: because moldy food contains aflatoxin, its carcinogenicity is very strong, easy to induce liver cancer.
As early as 1993, aflatoxin was classified as a class 1 carcinogen, which is 70 times more carcinogenic than methamphetamine and 68 times more toxic than frost, so eating moldy foods regularly is likely to cause liver cancer.
Chinese salty fish: salty fish production needs to be dehydrated, and in the process will produce some nitrosamine compounds, these substances have carcinogens, often eat salted fish will increase the incidence of nasopharyngeal cancer, and salted fish similar pickles, bacon, etc., containing nitrite into the body and protein decomposition, will form a carcinogenic nitrosamine, so it is best to eat less.
Of course, with a cancer risk is not equal to 100 percent carcinogenic, the dose aside from toxicity is "rogue", therefore, whether cancer also needs to see the dose, only after reaching a certain amount, it is possible to cause cancer.
maintain good eating habits, exercise more, improve the body's immunity, reduce the risk of cancer.
