On October 26, the world health organization's international agency for research on cancer (iarc) published a report on its official website, will be processed as a carcinogen, at the same time will have red meat as carcinogenic potential higher food, causing global debate, the public and media also followed suit in our country. "Ham, bacon, interacting with asbestos, arsenic" belong to carcinogen, let many people confused even concern: don't later can't eat meat?

"It doesn't mean eating processed meat is very dangerous"

The international agency for research on cancer (iarc) established a carcinogenic classification system, carcinogens can be divided into 4 grade 5 classes, and is widely used around the world.

According to the grading system, class 1 carcinogen refers to research has sure effect that cause cancer to human material; 2 a kind of carcinogenic substance is to point to in the animal experiments have sufficient evidence, it is not clear to the human body, but in theory there is carcinogenic substance, known as the carcinogenic potential of higher material; Class 2 b carcinogen is refers to the animal experimental evidence is not sufficient, human trials more limited evidence material, called a lower risk carcinogenic substances.

The international agency for research on cancer concluded that there are strict requirements for class 1 carcinogen, must have the strict design, reliable method and can eliminate the epidemiological investigation of confounding factors have a dose-response relationship; With the survey data validation support or animal experiment. Previously have been listed in 1 kind of carcinogenic substance has more than 80 kinds, including tobacco, asbestos, arsenic, etc.

The agency listed in the report of processed meat products such as sausage, ham, dried meat, canned meat, and said from 10 countries about 800 22 experts analyzed meat link between diet and cancer research, and concluded "eating processed meat products can lead to colon cancer... 50 g eating processed meat a day, had a 18% increased risk of colon cancer" conclusion.

"Processed meat is a carcinogen, but it doesn't mean eating processed meat how dangerous it is, it 'as' a little grandstanding and tobacco, arsenic." A food safety expert told reporters.

Dr. The international agency for research on cancer (iarc) rumi said publicly that carcinogenic risk of cancer is not the same, the normal consumption of meat and red meat, and under the environment of asbestos work compared with smoking, your risk of cancer is tiny.

A balanced diet deserves more attention

"Different epidemiological investigation may give different data, different individuals are different carcinogenic risk." Tumor hospital of Peking University, said Fang Yu, director of the nutrition meat products are classified as carcinogens, red meat is listed as carcinogenic potential higher food, does not mean that these food cannot eat. Fang Yu said, leaving intake talk about food and the risk of cancer is meaningless, don't eat meat is unlikely, but don't eat red meat is not scientific, the "red meat after all have irreplaceable nutrition".

So how do I eat the meat and red meat? Fang Yu proposal, cattle and sheep red meat such as pork, chickens, ducks and other white meat, fish and shrimp and a best change to eat the next day. Every time the red meat intake of no more than 100 grams, white meat, not to exceed 150 grams, and processed meats such as bacon, ham, try to avoid intake.

The world cancer research fund in 2012 released a new version of the food, nutrition, physical activity and cancer prevention, "the report also notes that red meat could be important for colorectal cancer, so eat red meat must be restricted, intake had better not more than 500 grams per week, and as far as possible make the healthy cooking style, avoid salted or baked, etc.

Fang Yu said the epidemic research evidence, right amount to eat some plant foods, particularly vegetables, fruits, and at the same time reduce the animal food, particularly red meat and cooked meat products, to reduce the risk of cancer. But as a result of nutrition research is very difficult to separate different foods and nutrients alone to study, even if found some nutrition known as anti-cancer effects, the synergy of cannot be ruled out a variety of nutrients, "a balanced diet is the most scientific principle and the key, the diversification of the food species and quantity of balance".

Fang Yu said, now the public easily attracted by the concept of carcinogens, additives, but as long as the intake in a safe range, there is no need to worry about, "food hygiene, by contrast, more worthy of attention and dietary balance".
