What are the top ten junk foods?

Top Ten Junk Foods in the World Published by the World Health Organization (WHO)

First, fried food.

1, the culprit of cardiovascular disease (fried starch)

2, containing carcinogens

3. Destroy vitamins and denature protein.

How much does baking fried food affect people's health?

According to medical research, atherosclerosis began at the age of 7. At present, the culprit is selling local workers and fried foods such as KFC.

It will also gain weight and cause cancer.

Second, pickled food.

1, leading to hypertension, renal overload and nasopharyngeal carcinoma.

2, affect the mucosal system (harmful to the stomach)

3, easy to get ulcers and inflammation

Like mustard tuber

People who often eat greasy food, people who have recovered from a serious illness or a minor illness and have a bad appetite are especially suitable for eating. Diabetic patients and pregnant women should eat mustard tuber as little as possible, and people with chronic diarrhea should not eat it.

Three, processing meat food (dried meat, meat floss, sausage, etc ... )

1, which contains one of three carcinogens: nitrite (anti-corrosion and color development)

2, containing a lot of preservatives (increasing the burden on the liver)

Preservatives encountered every day

In daily life, preservatives are indispensable from soy sauce and jam in condiments to various cakes and drinks, as well as various processed foods and packaged foods. Preservatives can prevent food from spoilage and sometimes food poisoning. These are undoubtedly beneficial to the health and safety of consumers.

Preservatives are all synthetic, and improper use will have certain side effects, and long-term excessive intake will definitely cause harm to health. If you take too many preservatives, it will cause symptoms such as drooling, diarrhea, abdominal pain and rapid heartbeat. In severe cases, it will cause serious harm to the stomach, liver and kidney, and it will also increase the incidence of cancer.

Pigment is toxic, too?

Pigment is not an illegal additive, and adding pigment to food is not a patent of modern people. In ancient China, people knew that monascus pigment was used to brew red wine. The bad influence of the "Sudan Red Incident" that broke out not long ago made people more suspicious of pigments with poor reputation. Of course, Sudan red is actually an industrial dye, not an edible pigment.

As long as the edible pigment is used within the scope and standards allowed by the state, it will not cause harm to health.

However, there are always some unscrupulous traders who add too much pigment in pursuit of profits. Consumers should avoid buying too bright food when choosing food, and remember not to be confused by that gorgeous coat.

4. Biscuits (excluding low-temperature baking and graham crackers)

1, too much pigment in edible essence (burden on liver function)

2, serious damage to vitamins

3. Too many calories and low nutrition.

The content of trans fatty acids in natural foods is very small, and the foods containing trans fatty acids that people usually eat are basically from foods containing margarine. Even foods containing hydrogenated vegetable oils may contain trans fatty acids. The most common is baked goods (biscuits, bread, etc. ), salad dressing, French fries, fried chicken pieces, onion rings and other fast food, as well as western-style cakes, chocolate pies, coffee companions, hot chocolate and so on. However, trans fatty acids have different names. Generally labeled as hydrogenated vegetable oil, vegetable shortening, margarine, margarine, vegetable butter, margarine, shortening or non-dairy creamer, which may contain trans fatty acids.

Five, soda cola food

1, containing phosphoric acid and carbonic acid, will take away a lot of calcium in the body.

2, the sugar content is too high, and there is a feeling of fullness after drinking, which affects the dinner.

Like coke.

Shake hands ... I also drink Pepsi as water. I just don't drink water, it's still cold. Ha ha. ...

In the words of a nutritionist, coke is used to clean toilets. Drinking coke has many disadvantages, some of which are quite serious.

However, I am willing to be poisoned by coke, which is called "pain and happiness"

Coke is an out-and-out "drug": like all soft drinks, it is a 100% unnatural monster. Except for water, there is no ingredient that is beneficial to the body, but it is obviously harmful.

A can of coke contains seven teaspoons of sugar, which makes people fat, tooth decay, sour body, disordered brain operation and emotional instability ... and the disadvantages are endless. Coke contains various dyes and seasonings, which hinder the functions of various parts of the body. Carbonated drinks, such as soda and cola, contain almost no vitamins and minerals. The main ingredients are sugar, pigments, spices and carbonated water, and there are no nutrients except some calories.

According to a survey conducted by Harvard University, teenagers, especially girls, who often drink a lot of carbonated drinks are three times more likely to have fractures than other teenagers. Researchers believe that the reason may be that phosphoric acid contained in carbonated drinks affects bone deposition and has side effects on bone growth. Carbonated drinks have a good thirst quenching effect in hot weather, which is almost not good for people's health, and it is more harmful to drink too much.

Coke is mainly composed of syrup and carbon dioxide gas. No nutrition for the body.

Regular drinking of cola will not only lead to obesity, but also lead to dental caries, osteoporosis and heart disease. It is also a potential risk factor for modern diseases such as diabetes.

Not to mention the harm of pigments, spices, caramel and other additives contained in cola to human body, only caffeine is a substance harmful to health.

Coca-Cola and grapes are Hong Kong people's favorite drinks, but a survey by the School of Dentistry of the University of Hong Kong shows that if you drink three cans a day for many years, you may have a toothache.

The School of Dentistry of the University of Hong Kong randomly sampled 20 kinds of paper-packed, canned and bottled beverages containing acidity and sugar, and found that 18 kinds of beverages had high acidity, which could dissolve tooth enamel, among which the acidity of cola and grapes was much higher than the index. The professor of dentistry pointed out that if you drink 1 liter of acidic and sugary drinks every day for 1 to 2 years, the enamel on the tooth surface will be corroded by acid.

Prince Philip Dental Hospital receives nearly 20 complicated cases of teeth being corroded by acidic drinks every year. Some patients drink several cans or bottles of coke every day, and almost all the enamel that protects their teeth is corroded by acid.

The pH value is between 1 and 14 degrees, and 7 degrees is neutral. If the acidity of the beverage is lower than 5.5pH, the enamel can be dissolved.

Caffeine is a drug that can excite the central nervous system, heart and blood vessels and damage memory.

In addition, for children, caffeine is irritating, which can stimulate gastric peristalsis and gastric acid secretion, causing intestinal spasm. Children who often drink coffee are prone to unexplained abdominal pain, and long-term excessive intake of caffeine can lead to chronic gastritis. Caffeine can dilate capillaries in gastrointestinal wall, stimulate renal function, increase renal water flow, lead to polyuria in children, increase calcium excretion, and affect children's bone development. At the same time, caffeine can also destroy vitamin B 1 in children, causing vitamin B 1 deficiency.

A can of 355ml cola contains 65mg of caffeine, a can of 350ml oolong tea contains 80- 120mg of caffeine, and a cup of instant coffee contains 85-200mg of caffeine. Normal people should not consume more than 200 mg of caffeine every day, otherwise they may be chronically poisoned. Children should stay away from coffee and drink caffeinated drinks as little as possible.

And some chemicals in cola, such as sodium, can raise blood pressure. Experts warn that high blood pressure will increase people's risk of heart disease, stroke and kidney disease, which cannot be ignored.

Coke is really harmful to human body.

1, cola contains caffeine, which will be addictive if you drink it for a long time.

Coke contains carbonic acid, and drinking too much is bad for your health. Because the human body is weakly alkaline

In the best condition.

3. Nothing lacks nutrition like protein.

4. Long-term drinking will make you fat, because it contains sugar.

In addition, when the carbonated beverage represented by cola was first introduced, because of its good taste, the gas produced can take out the heat in the stomach, giving people a feeling of comfort and excitement. With drinking habits, people will have a certain dependence on carbonated drinks. Actually, carbonated drinks have no nutritional value.

According to reports, all kinds of carbonated drinks are high in sugar, and long-term drinking can easily lead to obesity. Coke contains caffeine sodium, similar to caffeine, and also contains preservatives. These ingredients are not good for health and have no nutritional value. Drinking these drinks for a long time will definitely cause problems.

Experts suggest that you should drink carbonated drinks as little as possible, especially for children, women and the elderly, and it is best not to drink them. "In fact, the best drink in China is our national drink-tea, especially green tea. Even drinking boiled water is better than drinking carbonated drinks. "

It is harmful for children to drink coke. Cola contains caffeine, and 1 bottle of 340g cola beverage contains 50-80mg caffeine. Someone has done experiments. Adults who take caffeine more than 1 g at a time can cause central nervous system excitement, accelerated breathing, tachycardia, insomnia, dizziness and tinnitus. Even if the dosage of 1 time is less than 1 g, poisoning symptoms such as nausea, vomiting, dizziness, palpitation and precordial pain will occur due to the stimulation of gastric mucosa. Children are more sensitive to caffeine than adults, so don't give them cola drinks.

Young girls drink cola to prevent osteoporosis. Studies have shown that soda can accelerate bone loss, especially for girls who love to drink cola, and the probability of fracture is five times that of those who don't drink soda!

Experts pointed out that phosphoric acid in cola may be the cause of easy fracture. Phosphoric acid is harmful to bones because it has adverse effects on calcium metabolism and bones. On the other hand, young girls who drink cola may have insufficient milk intake, which leads to calcium deficiency, so they are prone to fracture.

Newlyweds should also be careful when drinking coke. Because most cola drinks contain high content of caffeine, caffeine can easily enter the fetus through the absorption of placenta in the body, which will harm the brain, heart and other organs of the fetus, and also cause fetal malformation or congenital diseases. Therefore, experts suggest that newlyweds and couples who want to have children should not drink cola drinks except smoking. Even after the baby is born, lactating mothers can't drink cola drinks. Because caffeine will also enter the baby indirectly with milk, which is harmful to the baby's health.

Old people shouldn't drink coke. Cola has diuretic effect, which can reduce the absorption of calcium by half. Old people often drink caffeinated drinks, which will aggravate the lack of calcium in the body and easily lead to osteoporosis and fractures.

In addition, drinking too many caffeinated drinks will increase blood lipids and easily aggravate arteriosclerosis. Patients with hyperlipidemia and hypertension drink more alcohol, which will accelerate the deterioration of their condition. For smokers, caffeine can easily mutate some tissues of the body and even lead to cancer cells under the action of nicotine mutagen. In order to avoid the above hazards, we should change the habit of smoking and drinking coke at the same time.

Recently, the reporter learned that the world-renowned soft drink manufacturers Coca-Cola and Pepsi-Cola reached an agreement on June 25, 2008 to stop broadcasting beverage advertisements for children under 65,438+02 in the European market.

Six, convenience food (mainly refers to instant noodles and puffed food)

1, the salt content is too high, and it contains preservatives and essence (liver injury).

2, only calories, no nutrition

Such as instant noodles.

Because of its convenience, instant noodles can be said to be the essential food for most students. Instant noodles have become an ideal fast food for consumers because of their convenience, time saving and economy.

I am too lazy to buy breakfast noodles in the morning, and I am very hungry before going to bed at night. But instant noodles are harmful, so it is best to eat less. Let's look at its "structure". At present, there are more than 300 kinds of food additives, which have many functions, such as coloring, bleaching, regulating appetite, antioxidation and prolonging shelf life. These additives can be used according to regulations. It is not a big problem for us to eat a few meals occasionally, and it is difficult to ensure our health.

The following are several additives in instant noodles:

Salt A packet of instant noodles contains 6 grams of salt, and our daily intake of salt is about 8 grams. Therefore, the salt content of instant noodles is obviously high. Eating too much salt is easy to get high blood pressure and damage the kidneys.

Phosphate can improve the taste of instant noodles. However, too much phosphorus intake will make the calcium in the body unable to be fully utilized, which will easily lead to fractures, tooth loss and bone deformation.

Grease. Instant noodles are fried, which can reduce the moisture in noodles and extend the shelf life. However, these oils become "oxidized lipids" after oxidation, which accumulate in blood vessels or other organs, accelerate human aging, cause arteriosclerosis, and easily lead to cerebral hemorrhage, heart disease and kidney disease.

Antioxidant. Instant noodles are as short as a month or two and as long as a year or two. The added antioxidants and other chemicals have slowly deteriorated, which is harmful to people. Eating instant noodles for a long time will bring harm. (1) The main ingredients of instant noodles with malnutrition are flour and oil. In addition, there are some monosodium glutamate, salt, oil and Chili powder in the seasoning bag. Some so-called "delicious and visible" instant noodles, plus a small bag of dried vegetables or a very small amount of minced meat. Protein, fat, carbohydrates, minerals, vitamins, water and cellulose cannot be fully utilized. After frying, the vitamin B originally rich in instant noodles was completely destroyed. Instant noodles can basically only provide the heat needed for human activities. Because instant noodles have only staple food and no dishes, they often need to increase their food intake. The result is an excessive intake of carbohydrates and fat. Therefore, eating instant noodles often will inevitably lead to long-term excessive intake of fat and calories, which will lead to obesity and promote the occurrence of obesity-related diseases such as heart disease, diabetes, hyperlipidemia and hypertension. At the same time, due to the long-term lack of other nutrients, it will cause malnutrition in the human body, which will lead to a series of diseases such as dizziness, fatigue, emaciation, palpitation and listlessness. In severe cases, nutritional deficiencies such as weight loss and muscle atrophy may occur, and the consequences are very serious. According to the investigation of nutritionists, among the people who eat instant noodles for a long time, 60% are malnourished, 54% are iron-deficiency anemia, 23% are riboflavin deficient, 16% are zinc deficient, and 2% suffer from various eye diseases due to vitamin A deficiency. (2) Lipid peroxide is harmful to health. Antioxidants are usually added to the oil of instant noodles, but they can only slow down the oxidation rate and delay the rancidity time, but can not completely prevent rancidity. After rancidity, fatty foods will destroy nutrients and produce lipid peroxides, which are spicy. Long-term excessive lipid peroxide will destroy the important enzyme system of the body and promote premature aging. Therefore, instant noodles should not be eaten as a staple food for a long time.

It is best to pour out the noodle soup after flushing, and then add water or soup to reduce harmful substances such as salt. It's best not to put all the condiments in, just put half. Normal adults eat 1 ~ 2 packets a week, but instant noodles are only suitable for emergencies, and can be eaten at most once a day, not every day.

Master Kong's "instant noodle explosion". The hygiene inside is disgusting.

When it comes to "Ding Xin" International Group, there may still be many people who don't know much about it. Speaking of Ding Yi's "Master Kong" instant noodles, it is almost a household name. The advertising words of "delicious and visible" make many people unforgettable, and also make the sales of "Master Kong" instant noodles occupy an absolute market in the mainland. However, there are still many things that are "delicious". Now it is made public, and the result will make you dumbfounded, and it will also make many people who have eaten "Master Kong" instant noodles dumbfounded.

The production line needs carrot granules, but there are no qualified ones in the warehouse, only some of them are caked due to moisture. The section chief asked the workers to crush them with iron bars and feet for later use. At that time, a worker raised an objection and was too irresponsible to the customers who ate instant noodles. But Tang Kechang snapped, "Do as I say, or go home." Then the workers worked hard with iron bars and feet.

The advertisement of "Master Kong" has repeatedly claimed that artificial colors and preservatives are not added. What is the actual situation? 1September, 1997, "master kong" imported (dehydrated) about 14000 kg of dried shrimps from a factory in Zhuhai, Guangdong province. Almost all these dehydrated shrimps are sprayed with red artificial pigment. And the inspection will pass all the way until it is fully used. Since then, such goods have been imported continuously.

Among all the ingredients of Master Kong, there is a so-called "nutrient" that all mainland employees don't know. It is such a "nutrient" that many people want to solve its mystery, but they have never succeeded. Although these can't prove anything, people with a little common sense know that many foods will soon deteriorate without preservatives.

When you walk into Master Kong's factory, you will find a clear slogan posted on the wall: "Photographing and videotaping are forbidden in the factory." Ask the relevant personnel why, answer: commercial production secrets. Is that really the case?

The tempering workshop and pretreatment workshop are the first pass in the production of sauce packets. Onion, ginger, garlic, beef, etc. It's all crushed. The author saw that after the beef was taken out of the cold storage, it went directly into the meat cutter without washing it with water. The dirt on the beef is sliced together with other things and immediately enters the next meat stirring process. Asked why they didn't wash it, the team leader said that one class stirred so much meat, could it be washed? Wash the onion, ginger and garlic, but don't pick up the rotten garlic. The root of ginger is still attached to the mud. Even the black garlic in the back basket was sent to the stirring knife. When asked about a worker, he smiled and replied, "It's still good. Working at night will be dirtier. Rotten onions and garlic are common. " What we see here is just a link, and all the dirty things are unimaginable. It is the origin of the famous "Master Kong" sauce package seasoning.

Qin, a worker in a flour mill, said that when he was working in the flour mill, he worked night shift one day. Overworked, he temporarily lay on the water to rest. Unexpectedly, his ear was torn by a crazy mouse and the wound was still there. How many mice can the factory meet? This is also a paradise for mice. When they were on the night shift, groups of mice flew around the warehouse playing games. They are constantly shuttling between various fine powders and powders. The concentrated solution, powder, onion slices, carrots, beef, pork, sugar and salt chewed by these fat mice are processed into instant noodles and sold to our customers.

When throwing carrots in the "azo" workshop, the workers found a big dead mouse and a few small dead mice in time before throwing them in, otherwise the consequences would be unimaginable. However, according to the workers on duty, many inputs have not found this situation.

Ordinary people in the mixing workshop of aniseed and concentrate come here, and you can't stand the choking smell of concentrate. Through the smoky dust, you will see the workers who are covered tightly but are too dirty to see the true colors of their clothes, sweating like a pig. There was rubbish everywhere under their feet, and some concentrated materials scattered on the ground were collected by the workers and put into the pot again for stirring? All kinds of dust and sweat on the body are constantly scattered in the work of workers and flow to the stirring pot. How can this dirty thing remind people that the powder bag in the bag is the "Master Kong" powder bag? This is absolutely correct. A monitor said that our working environment was too bad and our clothes were dirty. As for the quality of concentrate, although there are tests, it is only a cursory look. Everything depends on the wishes of the section chief to make the output go up. And customers won't feel dirty after eating it. It has been like this for many years, and no one has eaten the dead. If we were serious, we might have gone home long ago. The monitor said: Sometimes I'm busy. I don't brush this mixer once every few months. Instant noodles are convenient to eat, but I didn't expect them to be convenient to make.

The bacterial content of small materials exceeds the standard. Dingyi Company has an unwritten rule that if the materials are unqualified, you can apply for "special procurement" and use them later. And the meaning of this "special mining" is just a word from a Taiwan Province manager. Those who fail can be qualified immediately. Ding Xin Group has a Fang Ding company, which specially transports four to five tons of garlic powder to Dingyi. If the test result is unqualified, it will be treated as "special collection" and will not be returned or replaced. If anyone objects, it's asking for it. The lighter will be punished, and the heavier will go home. In Ding Yi, this violation of food hygiene law was recognized and recognized by relevant leaders. Many abnormal review sheets are signed and confirmed by leaders. Therefore, some unqualified and untested products have been put into use, and some grassroots leaders are also very confident.

At the end of 1997, this kind of candy was cut off, but the person in charge of the relevant department ordered the workers to break the previously banned caked soft candy with a black hammer and continue to use it.

1April 8, 997, Dingyi Company carried out a large-scale cleaning of the air-conditioning workshop in response to the ISO9000 certification inspection. In the fresh-keeping cold storage, the workers swept up as much as a catty of mouse excrement from all kinds of frozen meat. A section chief suggested that beef eaten by rats should not be used again, but it was forbidden by Yan Sun, director of quality assurance department. The section chief and another section chief argued, but they were told that it would not be good for you to fight any longer. You should deliver the goods immediately and continue to use them, and you must inspect the goods before delivery, otherwise you will bear the consequences. Finally, all the beef chewed by rats was sent to the pretreatment workshop to make a "fragrant and sweet" sauce bag.

Many people may have eaten the "Master Kong" Chinese instant noodles in RP Workshop. Look at the gorgeous packaging and high price, it is definitely a boutique. But that big bag of beef was eaten by a large group of mice when it was stored in RP workshop at night, and then heated and bagged to make the finished product. Some Chinese sauce packets simply can't stand storage and often explode for unknown reasons. According to the warehouse manager of RP, the workers in the RP workshop don't eat beef in RP bags. Later, due to quality problems, a large number of products were overstocked, and the overstocked products had to be distributed to the employees of the conditioning factory.

1997 1 1 in the first ten days of the month, a factory director of noodle factory 1 visited the workshop and found a large area of urine beside the dough mixer. After careful examination, it was found that there was mixed urine. The director ordered a thorough investigation, but I didn't expect it to go away in the factory later.

Walking into the concentrated solution warehouse of the property management department of the conditioning plant, people will find that among the 45 varieties packed inside, except for 7 varieties such as soy sauce powder and Chili red, they are all packed in cardboard boxes. These cartons are divided into imported goods and domestic goods. The imported cartons are a little neater, and some domestic cartons are worn out. Especially the garlic powder sent by Fang Ding Company, which is filthy and disgusting. When asked how to deal with the inspection in such a sanitary environment, a supervisor replied cheerfully: "What's the matter? As soon as the inspection was notified, it was cleaned in one day.

Speaking of disgusting hygiene here, a worker said with a smile, you go to the raw material warehouse to ensure that you will never eat Master Kong instant noodles. The raw material warehouse mainly stores onion slices, carrots and broccoli. Because these things are lighter, the packaging box is bigger, and there are big plastic bags inside. It is these big plastic bags that have been artificially torn in many places. Smell it with your nose and you'll smell it right away. Among them, the degree of man-made damage is more serious than that of concentrate bin. These dirty concentrated solutions, powders and dehydrated vegetables are being processed into finished products and put on the market continuously. As the worker surnamed Liu said, I don't want to eat instant noodles of Master Kong all my life.

Seven, canned food (including fish and fruit)

1 destroys vitamins and denatures protein.

2. Too many calories and low nutrition.

● Contains preservatives. In order to prolong the shelf life, preservatives (such as benzoic acid) should be added to canned food during production. Generally speaking, the preservatives added in canned food have no toxic effect on human body, and a small amount of them are relatively safe for short-term consumption, but they are harmful to liver and kidney if they are eaten frequently.

● Contains additives. Additives are added to canned food to make it delicious. Additives added in the processing of canned food include spices, pigments and artificial flavoring agents, which are harmful to children.

● Loss of vitamins. After canned food processing, about 10%-60% of vitamin C, 20%-80% of vitamin B 1, less than 10% of vitamin B2 and vitamin PP, 20%-30% of pantothenic acid and15%-

Therefore, there are some defects in nutrition and hygiene of canned food on the market at present, which cannot replace fresh vegetables and fruits, and children are not suitable for eating canned food in large quantities.

Eight, plum food (preserved fruit)

1, which contains one of three carcinogens: nitrite (anti-corrosion and color development)

2, the salt is too high, containing preservatives, essence (harmful to the liver)

Preserved fruit, preserved plum and preserved fruit contain nitrite, which can combine with amine to form a potential carcinogen-ammonium nitrite. Additives such as essence may damage organs such as liver; Higher salt content may lead to higher blood pressure and heavier burden on kidneys.

Nine, frozen dessert food (ice cream, popsicles and all kinds of ice cream)

1, containing cream is easy to cause obesity.

2. Too high sugar content affects dinner.

If you eat too much ice cream, it's bad for your stomach. Eating several boxes at a time will affect the internal movement of the human body and cause diarrhea. ...

X. barbecue food

1, containing a large amount of "triphenyltetrapropylpyridine" (the first of the three carcinogens)

2. 1 Toxicity of roasted chicken leg = 20 cigarettes

3, leading to carbonation degeneration of protein (increasing the burden on kidneys and liver).

A few days ago, after three years of research, the World Health Organization recently selected and published six healthiest foods and ten junk foods, saying that eating barbecue is equivalent to smoking.

A research center in the United States reported that eating a roast chicken leg is equivalent to smoking 60 cigarettes. According to WHO, eating barbecue is equivalent to smoking 1 roasted chicken leg =60 cigarettes.

A research center in the United States reported that women who often eat barbecue have twice the risk of breast cancer as women who don't like barbecue food. Experts explained that because the meat is barbecued directly at high temperature, the decomposed fat drips on the charcoal fire and then combines with protein in the meat, which will produce a carcinogen called benzopyrene. If people often eat barbecue food contaminated by benzopyrene, carcinogens will accumulate in the body, which may induce gastric cancer and intestinal cancer.

Regarding the "toxicity" of barbecue foods, Hao, director of the Department of Occupational Diseases and Poisoning Medicine of Beijing Chaoyang Hospital, told reporters that because these foods contain high fat and calories, they have a great relationship with "modern diseases" such as hypertension, diabetes and cardiovascular diseases. Oil will change its chemical structure under the action of high temperature, which may have adverse effects on people's health.

It is understood that because the meat is directly barbecued at high temperature, the decomposed fat drips on the charcoal fire and then combines with the protein in the meat, which will produce a carcinogen called benzopyrene.

Induce gastric cancer and intestinal cancer

Experts explained that if people often eat barbecue food contaminated with benzopyrene, carcinogens will accumulate in the body, which may induce gastric cancer and intestinal cancer.

At the same time, there is another carcinogen in barbecue food-nitrosamine. Nitrosamines are produced in the pickling process before kebabs. If the curing time is too long, nitrosamines are easily produced.

Affect teenagers' eyesight

In addition, according to an authoritative study in the United States in recent years, eating too much cooked bacon will be threatened by diseases such as parasites, and even seriously affect the vision of teenagers, leading to myopia.

Frying is also harmful.

In addition to barbecue food, high-temperature vegetable oil and repeatedly used fried food will produce benzopyrene. This morning, the city's nutrition experts warned that the harm of fried food to health should not be ignored.

According to Dr. Yang Ziyan, a nutritionist in charge of the Nutrition Department of the Third Hospital of Beijing Medical University, the reason why doctors don't advocate eating fried food is mainly because oil will decompose into a substance called acrylamide under the action of high temperature. Acrylamide is produced by frying foods rich in carbohydrates at high temperature, which can induce benign or malignant tumors. At the same time, too much oil is easy to get fat, leading to high blood pressure, diabetes, cardiovascular diseases and so on.

The hazards of barbecue food mainly include the following aspects:

1. reduces the utilization rate of protein: the meat is roasted in the oven, vitamins and amino acids are destroyed, and protein degenerates, which seriously affects the intake of these nutrients.

2. Hidden carcinogens: In Maillard reaction, nucleic acids and most amino acids in meat are decomposed by heat, which may cause cancer.

3. Easily infected with parasites: the barbecue food is tender outside, and some meat is not cooked yet. If it is unqualified meat, the consumer may be infected with parasites and bury hidden dangers.

After barbecue, the nature of food tends to be hot and dry. In addition, cumin, pepper, pepper and other condiments are all spicy ingredients, which are very spicy and irritating, which will greatly stimulate gastrointestinal peristalsis and digestive juice secretion, which may damage gastrointestinal mucosa and affect physical balance.
