"The high incidence of cancer in China is the disaster caused by eating too much meat!"

"Pork and beef are listed as carcinogens abroad, and we are still eating a lot in China."

……

China is indeed a big meat consumer, and it can even eat half of the pigs in the world in a year. In 20 14 years, according to the statistics of the US Department of Agriculture, China people ate 57169,000 tons of pork a year, accounting for 52% of the global market.

With the improvement of the national economy, our consumption capacity of pork has also been greatly improved. Nowadays, pork is very common at the dinner table. It is worth noting that red meat, including pork and beef, has been listed as a 2A carcinogen by the World Health Organization. Is the high incidence of cancer in China due to eating too much meat?

1. Is the high incidence of cancer in China due to eating meat?

Carcinogenic factors are closely related to lifestyle, and everyone may get cancer. This paper published in The Lancet-Global Health, led by Academician He Jie and Professor Chen Wanqing of the National Cancer Center, analyzes the cancer risk factors related to common cancers in China, and the risk factors are as high as 23!

It can be seen from the specific risk factors that excessive intake of red meat and processed meat products is only one of them. Although this factor is classified as a kind of 2A carcinogen, it should be clear that the causes of carcinogenesis are quite complicated and are caused by many factors, so it is impossible to "generalize" that all red meat and meat products have high carcinogenicity, nor can we talk about the harm from the dose.

Wang, a national second-class nutritionist, said that in recent years, people have been "brainwashed" by various studies such as "red meat is related to the increased risk of cancer", leading to forgetting the nutritional value that meat itself can bring to the human body.

First of all, we should know that the "list of carcinogens" is divided into four categories, while category 2A carcinogens refer to human carcinogens with limited data, but they will cause cancer to animals. That is to say, pork, beef and other meats have been proved to be carcinogenic by animal experiments, but their effects on human body are still unclear. It doesn't mean that eating meat will definitely cause cancer.

Secondly, don't think too terrible about carcinogens. Carcinogens, in a strict sense, may only increase the risk of cancer. The risk is probabilistic and does not mean 100%. Moreover, the mechanism of carcinogenesis is quite complicated. If you can get cancer just by eating meat, it will be much easier for human beings to control cancer, and there will be no problem that cancer cannot be overcome.

Finally, we should know that red meat is rich in high-quality protein, heme iron, vitamins A and D, and it is one of the most important nutritional sources for human growth and development. You can't deny the full value that red meat can definitely bring just because it may cause cancer.

I remember a netizen left a message before: red meat causes cancer, so I use white meat instead of absolute safety.

Before discussing whether white meat can replace red meat, let's take a look at their respective nutritional values:

Red meat: the content of saturated fat and cholesterol is high; Rich in minerals; Rich in vitamin B 12, B6, nicotinic acid, etc.

White meat: a high-quality protein source, which is more easily absorbed by the human body; Low fat content; DHA contained in seafood is beneficial to improve the brain; Rich in vitamins and minerals such as calcium, phosphorus, potassium and iodine.

From this perspective, red meat and white meat have their own advantages in nutrition and do not overlap. It can be said that different people need different nutrition in the face of different nutritional needs, and no one can replace them.

The risk of cancer can be avoided. For red meat and processed meat products, limiting the consumption can not only meet the nutritional needs, but also reduce the probability of cancer, which can be described as everyone is happy. So how do you eat meat? Dr. Lin, from the Department of Health Management of Southern Medical University, said that how much to eat, which part to choose and how to eat are all exquisite.

1, weight recommendation

According to China's dietary guidelines, adults should consume 40-75g of livestock and poultry meat and 40-75g of aquatic products every day.

2. Recommended meat types

In terms of meat types, four-legged (such as pig, cattle, sheep and other livestock meat) is not as good as two-legged (such as chicken, duck, goose and other poultry meat), and two-legged is not as good as legless (fish and other aquatic products).

3. Selection of meat parts

Choose the part with low fat content, and the delicious and tender meat is high-fat meat. Everything that is neither fragrant nor firewood is low-fat meat. Such as chicken breast, rabbit meat and tenderloin.

4. Choice of cooking methods

When meat is roasted or fried, it not only loses a lot of nutrients, but also increases calories. Steaming, boiling, boiling and frying with less oil are relatively healthy cooking methods.

For meat-eating star Xiao Ai, not eating meat for a day is like not eating enough. Meat is a good source of protein. Eating correctly is easier to achieve than abstaining from meat, and it is also more beneficial to the body. Forget it. Let's make shredded chicken breast tonight. # Health Science Competition # # Health Star Project #
