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.

　　The Ministry of Industry and Information Technology can be said to be a very authoritative official spy website. About half a year before the new car goes on the market, the new car declared by the car company to the Ministry of Industry and Information Technology will be publicized. Like the publicity of other national ministries and commissions, the publicity of the Ministry of Industry and Information Technology is also very rigorous and meticulous. That is to say, as long as the models are exposed in the Ministry of Industry and Information Technology, they are basically in mass production. Ok, let’s take a look at the new car catalogues published by the Ministry of Industry and Information Technology in recent batches, and see the new car situation that will be listed in 2020.

　　Audi A4L

　　Time to market: April 2020

　　Highlights: the appearance has been greatly changed and new models have been added

　　As can be seen from the declaration drawing, the new car adopts the same latest design language as the overseas version in terms of appearance, and the hexagonal grille with a large mouth on the front face becomes flatter and wider, while the upper and lower sides of the grille are decorated with slender air inlets, and the left and right sides are connected with headlight groups with regular polygonal shapes. There are eye-catching grid LED light sources in the lighting groups, which still have strong recognition even if they are not lit.

　　On the side of the car body, the new car basically maintains the overall line of the old model, but the waist line adopts a three-stage design that breaks in the middle, replacing the old one, which is more dynamic.

　　In the rear part of the new car, the taillight area is mainly modified, and the internal light source becomes a grid corresponding to the front face. At the same time, there are chrome-plated decorative strips connected in the middle, which is more atmospheric with the rich chrome-plated decoration at the rear bumper.

　　In terms of power, the new car is still equipped with a 2.0T medium, high and low power engine, with the maximum power reaching 252 HP, 190 HP and 150 HP respectively, which is basically consistent with the current one, but on this basis, the new car has decentralized the Quattro four-wheel drive system to a medium power version of 190 HP and 40TFSI, giving users more choices.

　　The mid-term change of A4L has obviously increased the sense of sportiness from the front face, which runs counter to the luxury of the current models. Like A6L, it has started to take the sports route. As for whether the sales volume will increase after the official listing, let us wait and see.

　　Audi Q3 Sportback

　　Time to market: April 2020

　　Highlight: the styling design of the coupe.

　　As the coupe version of the new Q3, the new car continues the design language of the new Q3 as a whole, such as the same LED headlight group, hexagonal grille and S-line front enclosure. Q3 Sportback adopts a large-area hexagonal honeycomb grille, and the edge of the grille is surrounded by black lines. With the narrow and sharp headlights and the black elements in the fog lights on both sides below, it is full of sports atmosphere.

　　As for the power part, the declared vehicle is equipped with 2.0T, with a maximum power of 162kW, which is expected to match the 7-speed powershift, and equipped with quattro four-wheel drive system. In addition, the official said that more power systems will be added to this product in the future. In addition, the new car will have two-wheel drive and four-wheel drive models for consumers to choose from.

　　It was not long before BMW X2 was made in China, and its current sales volume was also suppressed by Q3. The next generation of Mercedes-Benz GLA did not continue its sports attributes, which means that almost no model in this market segment can be used to form a direct competitive relationship with Q3 Sportback. However, there are only 2.0T models in the power part at present. If you want to go further, you need to launch the 1.4T version as soon as possible.

　　Lingke 06

　　Time to market: or the first quarter of 2020

　　Highlights: It is an entry-level SUV with a plug-in version.

　　The front face design of Lectra 06 is different from that of 01 and 02 which have already been listed, but it is very similar to the Lectra 05 which has just appeared. In addition, the biggest difference between Lectra 06 and other known Lectra models is that this car comes from the same BMA platform as Geely ICON, not the CMA platform of Volvo XC40. The LECK 06 is smaller in size, with a length of 4340mm, a width of 1820mm, a height of 1625mm and a wheelbase of 2640mm, and its positioning is also lower.

　　In terms of power, the fuel version will be equipped with a 1.5T three-cylinder engine, with a maximum power of 177 horsepower and a peak torque of 265 Nm, matching a 7-speed dual-clutch gearbox. The fuel consumption of the Ministry of Industry and Information Technology is 5.9L per 100 kilometers, and the PHEV version will be equipped with a 1.5T engine and motor combination, matching a ternary lithium battery pack. The comprehensive power is still unknown.

　　Geely’s high-end brand Lectra has laid out three main products, 01, 02 and 03, as well as two derivative models, 01 PHEV and 03+. This year, Lectra plans to launch 10 brand-new products in China. 04 has confirmed that it will not be launched in the market, and 05 and 06 will be launched next. With the emergence of LECK 06 as an entry-level SUV, it can be seen that LECK’s product layout has explored the small SUV market and is ready to do a big job here. I believe that with the influence of the current LECK brand and the reputation of the model, the sales volume of 06 will not be too bad after listing.

　　Saic Volkswagen Viloran Weiang

　　Time to market: 2020

　　Highlights: Volkswagen brand’s first commercialized MPV

　　The new car adopts Volkswagen’s latest family design language. The oversized mouth bent downward has a total of six thick chrome-plated strips, which is very domineering, while the front bumper part has five chrome-plated decorations on the left and right, which is in line with the popular through grille modeling. The visual impact of the whole front face is not small, which is in line with the preferences of Chinese people.

　　In the rear part of the new car, a flat and slender C-shaped irregular polygon taillight is used, with a slender through chrome-plated strip connection inside, and a Volkswagen new car logo with letters below in the center of the chrome-plated strip, which has a good business temperament with the exquisite chrome-plated decoration at the rear bumper.

　　In terms of power, the new car is equipped with a 2.0T engine with a maximum power of 220 HP, and the fuel consumption per 100 kilometers can be as low as 8.1 liters.

　　In the domestic joint venture MPV market, Buick GL8 has been the world for many years. Although the price is more expensive than competing products, it still can’t stop selling well. However, Volkswagen brands have always paid insufficient attention to MPV, and there is only one domestic Touran L model. Will the launch of SAIC Volkswagen Viloran pose a threat to GL8? Let’s wait and see.

　　Chang ‘an Ford Explorer

　　Time to market: within 2020

　　Highlights: the domestic version has been greatly changed and is more suitable for Chinese people’s preferences.

　　Compared with the overseas version, the shape change of domestic explorers is quite obvious. Its front air intake grille adopts multi-banner air intake grille, and with sharp headlights on both sides, the whole vehicle looks more atmospheric and energetic. The thick bumper design at the top and bottom is also the core soul of the car, which highlights the visual experience of the hard-core SUV.

　　The tail has not changed much, and it still looks simple. The design of the taillight is different from the imported version, especially with the plated decorative strip in the middle, which is more layered.

　　In terms of power, the new car will be equipped with a 2.3T turbocharged engine of CAF488WQGR with a maximum power of 276 HP, which is expected to match the 10-speed automatic manual transmission and four-wheel drive system.

　　Ford explorers got up early to catch a late episode. When the SUV exploded, the explorers were not made in China, and now they are late. This time, let’s see if the brand-new Changan Ford Explorer can give strength after listing. Ford also needs a flagship SUV product to cheer itself up and enhance the reputation of existing brands.

　　Tucki P7

　　Time to market: the second quarter of 2020

　　Highlights: science fiction vehicle design

　　At the Guangzhou Auto Show in November, Tucki P7 just announced the pre-sale price (270,000-370,000 yuan after subsidy), which appeared in the new car declaration list of the Ministry of Industry and Information Technology. It can be seen from the information that the company name of the new car is still Haima Automobile Co., Ltd., and it should still adopt Haima qualification for production and sales.

　　The new car still adopts the design language of split headlights announced at the auto show. The head and tail lights are all split, with low streamline lines, hidden door handles, body measurements of 4880/1896/1450mm and long wheelbase of 2998mm, which is very atmospheric and futuristic.

　　Even if Tucki P7 takes the road of new energy vehicles, the pre-sale price has largely broken through the limit of its own brand cars. Such a high price, coupled with the label of the new power brand that makes consumers talk about color change now, will make the sales volume after listing really worrying in the future.

　　Saic Volkswagen tuyue pure electricity

　　Time to market: or early 2020

　　Highlights: the battery life reaches 300km.

　　In terms of appearance, the new car basically follows the design style of the fuel version, but the grille on the front part is filled with black bright decorative strips, which makes the grille basically completely sealed, in line with the consistent characteristics of electric vehicles.

　　On the side and rear of the car, it is basically the same as the fuel version. Of course, the tail mark e-THARU indicates the identity of the new car electric car. In terms of body size, the new car has a circumference of 4453/1841/1632 mm and a wheelbase of 2680mm, which is basically consistent with the fuel version.

　　Once listed, SAIC Volkswagen Tuyue has achieved good sales with the appearance of "Little Tuang". The launch of this pure electric version has met the needs of some consumers, which will further enrich the product pedigree and provide consumers who buy new energy SUVs with one more choice.

　　Honda’s new UR-V

　　Time to market: or the second quarter of next year

　　Highlights: The front face has changed greatly, and there are two power versions.

　　The new UR-V is a mid-term redesigned model, and the front face has changed greatly. The brand-new U-shaped large mouth front grille is painted in black, which is integrated with the headlights with the same black background design. The change of the tail is mainly due to the brand-new design of the internal cavity of the taillight group, and the thin chrome strip hook edge is added at the bottom of the taillight. As for power, the new car offers 1.5T and 2.0T displacement engines just like the current models.

　　The most minor modified model, the biggest change of the new car focuses on the appearance, and the fine-tuned front face and tail make the whole car look more recognizable. UR-V and Crown Road are sister models, and their product strength is not much different, but the market sales of UR-V are not as good as Crown Road, the reason is that the design is softer and less domineering. The new UR-V looks more imposing than the old models by upgrading its appearance. In a word, the new UR-V of Dongfeng Honda is still worth looking forward to.

　　Citroen C3L

　　Time to market: 2020

　　Highlights: High-site cross-border style

　　The shape of Citroen C3L is basically the same as that of the current C3-XR, and the headlights on both sides are connected with the penetrating chrome-plated middle net, which matches the oval air intake grille below, but it still looks a bit simple and honest, yes, this is French romance. The bumper is equipped with a black front lip, which is in line with the style of its crossover.

　　The length, width and height of this car are 4505mm, 1748mm and 1513mm respectively, plus the wheelbase of 2655mm. In fact, this size is also very sufficient for domestic consumers. Although this car is an ordinary car, its chassis clearance from the ground can even reach the distance of SUV, which is superior to ordinary cars in terms of vehicle extensibility and vehicle passability.

　　Although the height of the car body is great in practicality, the styling seems to have returned to the design level of French cars a few years ago. As for the market performance, it is better to give the answer to future consumers.

　　Chang ‘an Lincoln aviator

　　Time to market: or the fourth quarter of 2020

　　Highlights: from CD6 rear-drive platform.

　　In terms of styling, domestic aviators are basically the same as the imported models listed before, and the new car adopts the latest design language of the family, just like a scaled-down navigator.

　　As synonymous with American luxury, Lincoln’s various SUVs have already captured the hearts of many consumers with their calm and atmospheric shapes. This time, as the second domestic model that Lincoln will launch, aviators will also join hands with adventurers to compete in the domestic luxury SUV market.

　　Summary:There will be a lot of new cars announced by the Ministry of Industry and Information Technology in each issue. The above are just the key models selected. It can be seen that the new cars of joint venture brands are in a state of competition, and both the replacement and the small change are eye-catching. In the downturn of the auto market in 2019, manufacturers also know that in addition to the same environment, it is the best policy to rely on the hard power of products to make a breakthrough.
