Beef is one of the most common meats in people's lives. It is rich in protein and various nutrients, and has a very good nourishing effect. Fitness people eat more beef, which has the effect of increasing muscle. At the same time, beef tastes good, so beef has become a favorite of many people. However, there was news recently that the World Health Organization listed beef as a 2A carcinogen, so eating beef may cause cancer. As soon as the news came out, many people were too scared to eat beef anymore. What's going on here? Is beef still edible?

Beef is listed as a carcinogen, really!

First of all, it is not a rumor that beef is a class 2A carcinogen. The World Health Organization listed red meat as a class 2A carcinogen in 20 15. According to the definition of WHO, the red meat here contains the muscles of all mammals, and beef is of course a kind of red meat. Therefore, it is not false news that beef is classified as 2A carcinogen.

Class 2A carcinogens are not necessarily carcinogenic.

The authoritative World Health Organization lists beef as a carcinogen. Seeing this, do you think you can't eat beef anymore? In fact, the World Health Organization has classified carcinogens into many grades, and only 1 grade carcinogens have clearly confirmed that this substance has carcinogenic effect on human body. 2A Carcinogen only indicates that this substance may cause cancer, but the evidence of cancer is still limited.

At present, scientists have indeed observed that people who eat a lot of red meat for a long time are prone to cancer, but whether cancer is caused by red meat is still inconclusive. It is generally believed that the content of myoglobin in red meat is very high, and heme iron in myoglobin is one of the factors that may induce cancer.

You can continue to eat beef, but in moderation.

But talking about toxicity without dosage is playing hooliganism. The World Cancer Foundation expressed its views on the carcinogenesis of red meat. They believe that as long as the intake of red meat does not exceed 500 grams per week, it will not increase the risk of cancer.

So can we continue to eat beef? Sure! Beef is a good tonic, but you'd better enrich your diet in your daily life. Don't just eat beef and pork, it's better to add white meat such as chicken and fish. As long as you don't just eat a lot of red meat every day, but eat a variety of meat alternately, beef is still a safe and delicious food!
