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.

　　In 2020, Changan brand released its brand-new sequence UNI (Gravity), which focused on avant-garde and fashion. At that time, when all brands were conservative in design, UNI sequence occupied a place in the hearts of young car buyers with its advanced interior and exterior design and excellent performance. With the passage of time, today’s automobile market is full of flowers, and the products that make consumers feel refreshed are endless. In the environment of everyone’s "volume", the UNI sequence launched earlier can still maintain its popularity. Nowadays, the models of this series are updated and iterated one after another. Not long ago, the second-generation Changan UNI-V officially opened for pre-sale, and the new car is expected to be officially launched in the first quarter of this year.

　　Changan UNI-V is the first car product launched in this series, and the slip-back shape is also one of the best in the same class at that time. In 2023, Changan UNI-V series sold 156,700 vehicles, ranking the forefront of compact sports coupe. In January 2024, Changan UNI-V series sold 19,200 vehicles, a year-on-year increase of 114.2%. This time, the second-generation UNI-V of Changan has also been fine-tuned in the details of appearance configuration, and the fuel version and the Blue Whale Smart iDD plug-in hybrid version continue to be launched. The model that was actually shot at the store this time is Changan’s second-generation UNI-V 1.5T distinguished sports model.

　　Appearance and interior modeling are still avant-garde, optimizing details and enhancing sports attributes.

　　Changan’s second-generation UNI-V model has been upgraded in the front and rear styling, and the overall visual effect of the vehicle still presents a low-lying and sporty posture. This styling is a relatively avant-garde design, both before and now. For young users, there is nothing wrong with this design. This change has also made Changan’s second-generation UNI-V 1.5T distinguished sports style, which was actually shot in the store, add a lot to the sports atmosphere.

　　The head of the second generation UNI-V 1.5T distinguished sports car in Chang ‘an presents a low-lying design, and curved surfaces are designed on both sides of the cabin cover to make the head part more stereoscopic. The borderless grille design remains, but the diamond shape inside the grille is replaced by triangular pattern, and it is also more compact. Headlights are connected by decorative strips, and the front face is divided into upper and lower parts. The orange trim on the lower bumper also becomes flat.

　　The internal and external shapes of the headlights have not changed, and the interior is blackened. With the slender shape, it looks quite sharp. The headlights of real shooting models support mainstream functions such as intelligent far and near light switching and automatic opening and closing. The taillights highlight a certain sense of movement, and the interior of the lamp cavity also uses a triangular layout, echoing the front grille. The turn signal lighting has also become a flowing style.

　　Thanks to the design of the coupe, the side lines of the second generation UNI-V car in Chang ‘an are slender and smooth, and the blackened rearview mirror and window frame trims are decorated with orange trims. The visual effect still looks sporty, and the hidden door handle is not absent. In terms of body size, the length, width and height of the new car are 4720/1838/1430(1435)mm and the wheelbase is 2750mm, which is unchanged from the current model.

　　The slip-back shape makes Changan’s second-generation UNI-V look sporty from the rear, and it is also one of the car’s eye-catching designs. Compared with the current models, the overall shape of the tail has not changed much, and the electric tail is very B-shaped. The most conspicuous change is the change in the shape of the lower bumper and the rear exhaust. The exhaust design has been changed from a round mouth to a rectangular mouth, and the PHEV hybrid version will also adopt a double-outlet and center exhaust design.

　　All-black multi-spoke aluminum alloy wheels don’t look fancy, which is in line with the sports attributes of the whole vehicle. The real shot model uses SP SPORT MAXX series tires from Deng Lupu, with the specification of 235/40R19. The tyre size size is put on this car, which gives consideration to both performance and economy. The spare tire is still designed in a non-full size.

　　The interior modeling of the second generation UNI-V in Changan still maintains a dynamic design that echoes the appearance. The sharp lines and personalized instrument modeling make you feel like sitting in the cockpit of an airplane, which is also a feature of the UNI series models in Changan. The workmanship and materials used in the interior are very solid, and there are not many problems in the 100,000-class models.

　　The second-generation UNI-V 1.5T distinguished sports version of Chang ‘an has changed in interior materials and color matching compared with the current model. Among them, the interior color matching of orange/black color matching, the orange area is obviously reduced, and the center console also uses suede material with orange stitching, which converges a lot in color matching compared with the current models.

　　The steering wheel with flat design has a good grip and tight steering feel, but it takes some adaptation time to get started. The size of the 10.3-inch central control screen is not large, but the display effect is not bad, and it has not been upgraded compared with the current model. The difficulty and ease of use of the car machine system are not bad.

　　The built-in apps in the system are also rich, such as intelligent voice, intelligent navigation, online entertainment, information inquiry, etc., and can also be used for mobile phone interconnection and screen projection.

　　The design of the central armrest area is also relatively simple. In addition to the bar and the cup holder, the driving mode selection and the wireless charging panel of the mobile phone are also designed in this area, which will be more convenient to use. Below is a storage space with a large capacity, which provides USB and 12V power charging interfaces.

　　The proportion of the color of the integrated seat has changed, and there are more black parts. At the same time, the black parts have also become leather materials, and the "UNI-V" logo of the headrest has also disappeared and shifted to the hollowed-out silver trim under the headrest. I personally feel that the seat filler is a little harder than the cash. The front seats of the real shooting models are all multi-directional electric adjustment, and provide ventilation and heating functions.

　　The rear seats support a 4/6 ratio, which can effectively expand the storage flexibility of the trunk. The electric tailgate can be opened and closed from outside the car, inside the car and in the central control, which is very convenient to use. The hatchback opening method can also take things easily without bending over.

　　The wheelbase of 2750mm ensures the legroom of the rear passengers, and the shape of sliding back will have certain pressure on the rear head. After the panoramic skylight is opened, the lighting can be guaranteed, and the pressure on the rear passenger’s head can also be alleviated. The rear row has a central armrest and an independent air outlet in the rear row, and the cushion is somewhat short, which is not satisfactory for the thigh support of the rear passengers.

　　A traditional fuel version and a PHEV plug-in hybrid version are provided.

　　In terms of power, the second-generation UNI-V 1.5T premium sports version of Changan used a combination of 1.5T engine selection and 7-speed dual-clutch gearbox, and the maximum power and peak torque remained unchanged at 188 HP/300 N m compared with the current model.

　　The plug-in version will be equipped with a plug-in system consisting of a 1.5L four-cylinder engine and a motor, in which the maximum power of the engine is 110 HP, and the motor is 190 HP and 215 HP. The battery is equipped with two kinds of power batteries with capacities of 9.07kWh and 18.99kWh respectively, and the pure electric cruising range of CLTC under comprehensive working conditions is 50 km and 111 km respectively.

　　In other configurations, the car is also equipped with advanced driving assistance functions such as integrated adaptive endurance system, 540 transparent chassis, lane departure warning, front collision warning and parallel assistance. The configuration of independent suspension before McPherson also gives this car good comfort and handling ability.

　　Full text summary:The second generation UNI-V in Chang ‘an has been upgraded mainly for the exterior and interior parts, and the original superior configuration at the same level has been retained. I think this is also one of the reasons why the second generation UNI-V of Changan still has a place in consumers’ hearts with its excellent design and quality in today’s era of "volume" price and "volume" performance. It is reported that the new car will be officially listed in the first quarter of this year. At present, the new car has arrived at the store, and friends who like it can pay attention to it.
