The so-called processed meat products, that is, meat products that have been smoked, pickled and added with chemicals. Before the report was officially released, in the news of Crazy Network, expressions such as "Ham and bacon cause cancer, which are at the same level as arsenic" have caused heated public opinion.
In this regard, Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, School of Food Science and Nutritional Engineering, China Agricultural University, told Zhongxin.com that this statement is incorrect. "The so-called carcinogen means that there is relatively reliable evidence of carcinogenicity, but this is not directly related to carcinogenicity and toxicity." Fan Zhihong also pointed out that eating processed meat products will increase the risk of many diseases, which is not news, but common sense.
Previously, the International Agency for Research on Cancer under the World Health Organization had classified the carcinogenicity of substances into five grades, namely, carcinogenicity, possible carcinogenicity, possible carcinogenicity, uncertain carcinogenicity and possible non-carcinogenicity.
Luo Yunbo, a professor at the School of Food Science and Nutritional Engineering of China Agricultural University, told Zhongxin.com that a class of carcinogens does not mean that they are very strong carcinogens, nor can they be said to be the strongest carcinogens. This classification method is based on the clarity and possibility of carcinogenesis, not the intensity of carcinogenesis. According to this latest report, eating processed meat, such as bacon, sausage and ham, may indeed increase the risk of cancer. Eating 50 grams of processed meat every day, that is, two pieces of bacon, can increase the risk of colorectal cancer 18%.
Luo Yunbo said that "increasing the risk of cancer" does not mean that there is a causal relationship between eating processed meat products and cancer. "Processed meat products contain carcinogens, which does not mean that eating this food will definitely cause cancer. It depends on what you eat. If the intake is not much, the body's metabolic function will metabolize related harmful substances, so it will not get cancer because of eating some processed meat products. Of course, if you eat a lot for a long time, the chance of getting sick will increase. "
"Just like eating salt, eating too much salt can cause problems such as arteriosclerosis, but it won't work without salt. Everything has a relationship between quantity and effect, and quantity is not enough. If the accumulated amount can be metabolized, it can still be eaten. If toxic and harmful substances accumulate in the body faster than they decompose, it may be dangerous. " Luo Yunbo said.
Luo Yunbo believes that the labeling information about "ham and bacon cause cancer" in public opinion should be interpreted scientifically to avoid causing public panic. In addition, cancer varies greatly among individuals, and some conclusions drawn from current scientific research need to be slowly verified in practice.
"At present, food processing technology has gradually improved, additives, especially pathogenic additives, are decreasing, and more and more green processing methods are adopted." Luo Yunbo said.
Fan Zhihong also said that bowel cancer is a common cancer, and it is also one of the cancers with rapidly rising incidence in China. However, suffering from intestinal cancer is not affected by this factor. "Why do some people get cancer and some people don't? It is because these people have some bad habits that are easy to attract cancer. " Fan Zhihong said. Red meat is classified as a "suspected carcinogen". How to eat meat healthily? According to the report, red meat such as beef, mutton and pork is listed as "suspected carcinogen 2A", and glyphosate is also on the same list. Group 2A substance means that it may cause cancer to human body, while 1 substance represents a clear relationship with cancer.
For "meat lovers" who are unhappy without meat, Luo Yunbo said that to stay healthy, it is necessary to have a balanced diet. "It is impossible without meat, and at the same time, it is necessary to reasonably intake carbohydrates, vitamins and dietary fiber."
Fan Zhihong suggested that we should pay attention to the freshness when eating meat, and buy meat that has passed the health quarantine in regular stores. The amount recommended by the state is one or two to one and a half grams per person per day, that is, 50 to 75 grams.
"A small amount of food is to increase nutrition. Excessive intake of meat will not only increase the risk of intestinal cancer, but also increase the risk of hypertension and heart disease. Every food has its healthy and reasonable intake range. "
As for processed meat products such as sausages and bacon, Fan Zhihong said, "These things should be eaten occasionally, not at once."
The season changes, and the weather is dry and cool, which makes us vulnerable to viruses and colds. So, how should we resist the virus and keep healthy? Let me intr
