China Daily Global Online News: In recent years, the rapid economic development of China and India has attracted worldwide attention. In fact, apart from cultural, historical and political differences, the development of China and India has many parallel characteristics, especially institutional social inequality. Recently, two news stories that happened almost simultaneously in the two countries once again showed this parallel phenomenon.

Xinhua News Agency, Beijing, March 29: "The Ministry of Public Security of China held a national conference on public security management on the 29th, and one of the topics of the conference was to discuss the establishment of a unified household registration system in urban and rural areas, which means that the issue of canceling the dual household registration system in agriculture and non-agriculture that has been widely concerned in recent years is expected to be solved."

On the same day, The New York Times reported from New Delhi that an important affirmative action bill aimed at increasing and guaranteeing the quota of lower castes in Indian universities was shelved by the Supreme Court of India. This can be said to be a major setback for successive governments since India’s independence to eliminate the caste system, a social inequality.

The caste system represents the basic teachings of Hinduism, which was originally the need for Aryans to maintain their dominant position after conquering the South Asian subcontinent. However, after thousands of years, it has become a deep-rooted social bad habit. After the founding of the People’s Republic of China, there are two systems that cause hereditary inequality, but they are "new things", "political caste" divided according to family background, and China’s unprecedented "economic caste" represented by urban and rural hukou.

These two modern caste systems first hit the most creative strata in China society: urban intellectuals and the rural proletariat. The former victim was exposed through "anti-Rightism" and "Cultural Revolution", but the latter has so far lacked the attention of scholars. One of Deng Xiaoping’s great historical achievements is to completely get rid of the "political caste" based on family composition, and the resulting liberation of talents has become an important reason for China’s economic take-off. However, the "economic caste" represented by urban and rural hukou has been postponed to this day, which not only continues to hinder the creation of a "harmonious society" and economic development, but also leads to the absurd social inequality of "the same life but different prices".

As Singaporean Senior Minister Lee Kuan Yew pointed out in an interview with German magazine Der Spiegel in the summer of 2005, China, instead of Japan or other Asian countries, would have become the top power in Asia long ago if it had not taken the detour of the "Cultural Revolution", instead of causing international shock due to the "rise of China" today. This is really the golden advice of a generation of politicians.

If you don’t give advice in the past, you can catch up with others. For India and China, it is not only a necessary prerequisite to create a harmonious society, but also a key factor to decide who will win the development competition in the end. Especially in China, where the per capita natural resources are low, the difference between urban and rural hukou is a huge obstacle to the extensive development of human resources. It is expected that the recent national conference on public security management in Beijing will accelerate the early demise of the modern caste system in China.

Recently, I brushed a short video and saw some bloggers eating barbecue videos. Looking at the way bloggers ate with relish in the video, I couldn’t help swallowing.

Maybe many people, like me, are senior barbecue lovers. Although barbecue is delicious, we often hear some negative rumors about barbecue while eating. For example, a certain college student is diagnosed with cancer after eating barbecue continuously. For example, it is often said that barbecue causes cancer and cannot be eaten. …

Although these rumors look scary, they still can’t stop our love for barbecue. However, after carefully studying and consulting relevant literature, we found a truth that pierced our hearts:

The better the barbecue, the more carcinogenic it is!

Since barbecue causes cancer, does that mean you can’t eat it? Of course not! Let’s continue to look down.

Barbecue, why is it so delicious?

I have the most say in this question. Every time I go to have a barbecue, as long as I see the store baking ingredients with electricity, I always feel that the barbecue tastes wrong. Once a merchant bakes it with charcoal, I immediately feel that the barbecue tastes delicious.

I think the barbecue baked with charcoal is a real barbecue. The reason why charcoal barbecue is so attractive is that smoke will adhere to the surface of the ingredients during barbecue, which will bring a lot of volatile flavor compounds to the ingredients, and these substances are the real reason why we don’t want to leave when we smell them.

But if we use electricity to bake food, there will be no charcoal and water in the baking process, and no smoke will be generated. Whether we look at it or smell it, we will feel no appetite.

Barbecue, why does it cause cancer?

The ingredients baked with charcoal are attractive and delicious, but also bring the risk of cancer. And the root cause of cancer is related to two of them.

benzopyrene

The name of benzopyrene has been heard by many people. As a kind of carcinogen, it is clearly proved to have carcinogenic effect on human body. Studies have shown that benzopyrene is related to lung cancer, gastric cancer, skin cancer and digestive tract cancer. At the same time, benzopyrene has terrible teratogenicity and mutagenicity.

Why is there benzopyrene in the barbecue? The reason is very simple, that is, when the meat is grilled at high temperature, the oil in the meat will drip into the fire with the high temperature and produce smoke, which will also produce benzopyrene.

Studies show that the higher the temperature, the more smoke and the closer the food is to the fire source, the more benzopyrene may be attached to the food.

Heterocyclic amine

Heterocyclic amines are also high-risk carcinogens, and their carcinogenicity generally acts on blood vessels, intestines, liver, lymphoid tissues, skin and mouth, covering almost all aspects of the human body.

At the same time, heterocyclic amines have strong mutagenicity, including gene mutation, chromosome aberration, DNA breakage and oncogene activation.

The production of heterocyclic amines is also very simple, that is, the thermal reaction formed at high temperature will also lead to the reaction between amino acids in meat and glucose, and heterocyclic amines are born under this circumstance.

nitrosamine

Nitrosamines are also very common carcinogens. In order to make the barbecue taste better, some merchants will pickle the ingredients before barbecue. Once the curing time is too long, or too much salt is put, nitrosamines may be produced.

In addition to causing cancer, these problems of barbecue also need attention.

Health problem

This problem is more prominent, because in reality, many barbecue shops appear in the form of small stalls, and people often think that roadside stalls have the fireworks of barbecue. I don’t know that the ingredients are placed in the open air and are easily contaminated by microorganisms.

Preservation problem

The barbecue season is generally summer, and the temperature is high in summer, which is easy to breed bacteria. Once the operation of the barbecue shop is not standardized, the ingredients will easily deteriorate or go wrong.

Raw material problem

For a long time, the supervision of various barbecue shops or roadside stalls is actually very limited, which leads to that many of their ingredients, especially beef and mutton, cannot fully meet the hygiene standards. In addition, some "black-hearted" bosses do not hesitate to use "technology and hard work" for the benefit, such as taking duck meat as pork and taking scraps back for private processing.

Can air fryer cause cancer?

Air fryer has been very popular in recent years, but at the same time, there are negative news about cancer. The reason why the air fryer is labeled as carcinogenic is that it will cause some chemical and physical reactions of food when it works, and produce a substance called acrylamide.

Acrylamide was listed as a Class 2A carcinogen by the World Health Organization earlier, because it is generally believed that using air fryers will cause cancer.

It does make sense to look at it, but in fact it can’t stand scrutiny at all. The so-called class 2A carcinogen refers to "there is sufficient evidence to prove that it is carcinogenic to animals, but it is still impossible to prove whether it is carcinogenic to humans".

It is totally unnecessary to say that we feel carcinogenic when we hear acrylamide, and we are afraid. Because the "hot drinks above 65℃" and "staying up late" we often encounter are all Class 2A carcinogens.

What’s more, acrylamide is mainly the product of Maillard reaction between asparagine and reducing sugar, and Maillard reaction may occur in many processes that require high temperature cooking. Even if you use frying pan and frying pan instead of air frying pan, Maillard reaction may occur.

In addition, a study published in Food Science pointed out that compared with frying, the content of acrylamide can be greatly reduced by 90%.

Can baking food in an electric oven cause cancer?

Some people may say, since barbecue with an open flame will cause cancer, will cooking food in an electric oven also cause cancer?

This question is indeed very referential. After all, the popularity of electric ovens is very high now, and it is almost a necessity for every family.

As we said earlier, there are certain prerequisites for the production of carcinogens, and high temperature is one of the very important factors. Different from barbecue with naked fire, the advantage of electric oven is that the food will not directly contact with the heat source, so it will not produce lampblack, and the current electric oven can basically control the temperature and heat evenly, so it will not cause the local temperature of food to be too high.

Therefore, when roasting meat in an electric oven, as long as the temperature is controlled below 180℃ and the time is appropriate, observe and adjust the temperature at any time to avoid the food surface being burnt or burnt, you don’t have to worry too much about the influence of carcinogens.

How to reduce the harm of barbecue?

If you want to relieve your craving and reduce the health hazards of barbecue, you may wish to take a look at the following methods.

① Marinate the ingredients before baking.

What we are talking about here is not salting, but salting meat ingredients with seasonings rich in antioxidants such as garlic juice, lemon juice, rosemary or cinnamon powder. Studies have shown that this can reduce the generation of carcinogens.

② Remember to remove the burnt part.

Some people like to eat the burnt part, which is absolutely unacceptable, because the content of carcinogens in the burnt food is often higher. So when eating barbecue, try to remove the burnt part.

③ Wrap the ingredients before baking.

When barbecuing, you can wrap the ingredients with tin foil or lotus leaves before baking, because this will leave the lost water between the "coat" and the meat, and form a gap full of hot steam, so that the food will have the effect of steaming and baking, and the temperature will not rise so fast, avoiding too much carcinogen smoke from entering the ingredients.

④ Try to use less fat meat.

The fatter the meat, the more fat it means, and the more carcinogens it produces during barbecue. Therefore, try not to choose too fat meat when choosing ingredients.
