Do you believe it? About 40% of all cancers in the world are eaten, this statement is not alarmist. Chinese Academy of Medical Sciences Cancer Hospital recently announced the top ten cancer-causing food blacklist, "the top ten cancer-causing food blacklist" in WeChat, microblogging is frequently forwarded, people fear. In this regard, some doctors said the list is not scientific enough, easy to mislead the public.
But then again, there are studies that show that 80%-90% of human cancers are self-inflicted, 45% of which are related to diet and nutritional factors, while the others are caused by tobacco and alcohol, air and water pollution. What to eat or slow important, the following this "top ten cancer-causing food blacklist" or refer to it!
1, sunflower seeds:
Daily small amount of health decay spit out gargle
■Reason for the list:
Sunflower because of its fast growth, easy to absorb heavy metals in the soil lead, cadmium, nickel, the soil can be effective in alleviating the pollution of heavy metals, with the ability to purify the environment, for the best landscape green manure crops. But people eat into these heavy metals is harmful to the body, and eat sunflower seeds will consume a lot of choline, so that the body fat metabolism obstacles, resulting in the accumulation of large amounts of fat in the liver, will seriously affect the function of liver cells.
■Doctor's analysis:
The director of the nutrition department of Zhongshan Hospital affiliated with Fudan University said, from the growth rate to determine whether a plant can be eaten and not scientific, a variety of grains, vegetables, mushrooms, the growth rate of far more than sunflower seeds, and its ability to adsorb heavy metals is greater. The key to avoid eating heavy metals is to purify the land, otherwise any plant growing on it will be "poisonous". At the same time, the director said, including sunflower seeds, peanuts, almonds, cashews, pistachios are nuts, daily intake of a small handful of good health. But especially need to be reminded that nuts are prone to oxidation rancidity and moldy deterioration, if you taste bitter, moldy when consuming, be sure to spit out immediately, and rinse your mouth.
The deputy chief physician of the pancreatic, liver and gallbladder surgery department of the Cancer Hospital affiliated with Fudan University, and executive deputy secretary of the Shanghai Anti-Cancer Association, said that aflatoxin in rotten nuts is a proven strong carcinogen, and should be avoided as much as possible.
2, chewing gum:
Food additives are not all "tiger"
■Reason for the list:
The natural rubber in the chewing gum is non-toxic, but the production process used in the white piece of gum is added to the toxic vulcanization accelerators, antioxidants, and other additives to stimulate the gastrointestinal tract and cause discomfort. discomfort. And chewing gum in the sugar substitute aspartame is also carcinogenic.
■Doctor's analysis:
Chewing gum will contain some additives and sugar substitute aspartame, but as long as a person is not every day into pounds of intake, there will be no safety hazards. However, doctors do not recommend chewing gum for more than 20 minutes because too much chewing can cause strain on the oral muscles.
Said, and aflatoxin, nitrites and other substances that have been proved to be clearly carcinogenic, some additives are still in the stage of possible carcinogenicity or suspected carcinogenicity, but as long as the amount of intake in the safe range, food additives are still safe. If consumed in large quantities, they may cause health hazards.
3, monosodium glutamate (MSG):
Half of these ingredients are beneficial to the body
■Rationale for the list:
Monosodium glutamate (MSG) half of which is beneficial to the body of the levoglutarate L-Glutamine, but the other half of the body can not be utilized by the body of the levoglutarate D-Glutamine into a hazardous body of free radicals. The daily intake of MSG per person should not be more than 6 grams, excessive intake will make the blood glutamic acid and sodium levels rise, reducing the body's use of calcium and magnesium, may lead to calcium deficiency, affecting the strength of teeth and bones. It can also cause short-term headaches, panic, nausea and other symptoms, and has an adverse effect on the human reproductive system.
■Doctor's analysis:
The director said, either the U.S. FDA, the World Health Organization or the European Union, have now passed the safety monitoring of MSG. MSG, as well as chicken essence to create the "fresh" taste is sodium glutamate, this component is widely available in natural foods, even without MSG, food still tastes good. So far, no studies have proven that MSG is harmful to humans. However, MSG does contain a certain amount of sodium, dishes with MSG, you can properly reduce the salt.
4, pig liver:
There are also a large number of nutrients, especially iron
■Reason for the list:
Pig liver per kilogram of cholesterol up to 400 mg or more, too much cholesterol intake will lead to atherosclerosis, while the liver is a detoxification organ, will accumulate a large number of Aspergillus flavus toxin, antibiotics, sleeping pills and other metabolic toxins, so the pig liver should not eat.
■Doctor's analysis:
The director said, pig liver cholesterol is high, obese overweight, high cholesterol people try not to eat. At the same time, pig liver is really metabolic detoxification organ, but this does not mean that you can not eat. As a natural food, pig liver also has a large number of nutrients, especially iron, the key depends on who to eat, how to eat method. The urban population has a considerable number of people with anemia, especially women and children, how to avoid toxins, but also to get the nutrients in pig liver? The director says that small amounts are a good way to do this, for example: you only need six or seven slices of pork liver in a pork liver soup, share it with the whole family, eat two or three pieces each, and cook it two or three times a week. In addition, from a safety point of view, it is best to buy their own raw branded pork liver home cooking safer.
5, doughnuts, river noodles, rice noodles, fans:
Eat up to once a week
■Reason for the list:
In the production process are necessary to add alum (potassium aluminum sulfate), such as eating these things, easy to lead to anemia, osteoporosis; at the same time, the body of aluminum is too much, it is difficult to be excreted from the kidneys, toxic to the brain and nerve cells, and even cause Alzheimer's disease. In addition, the oil used repeatedly to deep fry, excessive oxidation is also harmful to health.
■Doctor's analysis:
This is basically correct, the oil in the cooking process of the doughnut is usually used repeatedly, resulting in excessive oxidation. The river noodles, vermicelli type of food, in order to be able to make its taste gluten, some vendors will be in the production process to add more alum, if often eaten, will have a certain impact on health. But the average person will not eat every day, if not more than once a week there will be no health risks.
6, pickles, dried radish:
Pickled within 24 hours or more than 20 days to eat
■Reason for the list:
Long-term eating will cause sodium, mercury retention in the body, thereby increasing the chance of heart disease.
In addition, also contains amine nitrite or there are bad operators with formalin preservation, these are carcinogens, easy to induce cancer.
■Doctor's analysis:
Pickles and pickles can have different properties due to different production methods and different additives. But almost all pickles and sauces will contain nitrites, which are carcinogens.
The director revealed that nitrite levels are highest when the food is pickled with salt for 24 hours to 20 days after pickling, so if you like to eat pickles, try to consume them in two time frames: within 24 hours or more than 20 days after they are made.
The director also mentioned that compared to pickles, kimchi is relatively safe, and the vegetables produce probiotics during the soaking process, which is healthier for the body. In addition, try not to buy bulk kimchi or pickles, it is best to buy packaged, branded and shelf-life.
7, commercially available bottled juice drinks:
Most of the sugar and flavoring by the blend
■Reason for the list:
Which added too much sugar, higher than the calories of the soda, it is recommended to eat fresh fruit or freshly squeezed juice.
■Doctor's analysis:
The director said that most of the sweet drinks are made of sugar and flavorings blended out, generally adding 8-15 cubes of sugar per bottle. A 500-milliliter bottle of sweet drinks, if you can taste the sweetness when you drink it, it is basically to put 14-15 cubes of sugar. Most of these sweet drinks contain "empty heat", that is, in addition to sugar, almost no other nutrients, and the human body in the metabolism of sugar need to consume a lot of vitamins B and C.
At the same time, the director also does not recommend freshly squeezed juice, on the one hand, because the juice machine, if you do not wash the machine in a timely manner after the extraction is complete, it is easy to On the other hand, many restaurants and beverage outlets sell freshly squeezed juice with various additives, and even the pulp may be fake. Doctors suggest that it is best to eat the original fruit directly.
8, eggs:
Eat no more than once a week
■Reason for the list:
Eggs contain a certain amount of lead, often eaten will cause lead poisoning. The symptoms of lead poisoning are insomnia, anemia, hyperactivity and mental retardation.
■Doctor's analysis:
Traditional methods of making out of the skin eggs does lead to a certain amount of lead deposited in the skin eggs, the modern new process of using zinc salts, so that the content of lead has dropped dramatically, and the occasional consumption of health will not be affected. The director reminded that it is important not to consume too many times, no more than once a week, and to buy branded packaged products through regular channels.
9, stinky tofu:
Doctors "least recommended food"
■Rationale for the list:
Stinky tofu is very easy to be contaminated by microorganisms during the fermentation process, which also contains a large number of volatile salts of nitrogen and hydrogen sulfide, etc., is a protein decomposition of the corrosive substances, harmful to humans.
■Doctor's analysis:
Stinky tofu is a food not recommended by the director. First of all, the production process of stinky tofu is very easy to add "stinky essence", which smells quite "classic" smell of stinky tofu is actually a chemical material; secondly, stinky tofu on the black part of the collection of heavy metals and toxic residues, easy to cause cancer; Secondly, the black part of stinky tofu often collects heavy metals and toxic residues, which are carcinogenic. The safety of stinky tofu from roadside stalls is not guaranteed, much less eaten!
10, popcorn:
Eat more may get "popcorn lung"
■Reason for the list:
Doing popcorn converter contains lead, in the high-pressure heating, the lead in the pot will melt a certain amount of lead, a part of the lead will be transformed into lead vapor and smoke, contamination of raw materials, especially in the last! The moment of "popping". Popcorn contains up to 10 mg / 500 grams of lead or so, the human body (especially for children) of the hematopoietic system, nervous and digestive systems are harmful. Eating too much may get "popcorn lung".
■Doctor's analysis:
The traditional method of making popcorn as the post said there is a certain risk of lead intake, but the possibility of suffering from "popcorn lungs" is extremely small, the United States has a case, the reporter interviewed the Shencheng doctor, so far there has been no relevant case report. Modern people are more likely to consume popcorn sold in front of theaters, in recent years there is a trend of high sugar and salt, many people find that the popcorn is now sweeter than before, slightly salty, chewing is also more crunchy, this is because of the addition of more sugar, salt, butter, sweeteners and other ingredients.
The director said theater popcorn is definitely a high-calorie, high-fat, high-additive food, with a large cup having more calories than two bowls of rice. But popcorn is also a food that can bring pleasure, doctors recommend that consumption of a certain amount of control, you can minimize the health risks, it is recommended that two people share a small cup at a time.
Said, like the "top ten cancer-causing food blacklist" such a list is not scientific, because including cigarettes, barbecue food in the charred part are clear carcinogens, cigarettes may not only lead to lung cancer, but also related to a dozen kinds of cancer. Even, if you only eat meat every day, it will also cause cancer-related factors. Tumor production, not a day to eat out, but a chronic disease, you every moment of every day, every moment of change, will affect whether the tumor is produced.
Like diabetes and cardiovascular disease, cancer prevention and fight against cancer should not start from the beginning of cancer, not from the age of fifty, but "from the child", the earlier the prevention, even if the congenital hereditary risk is high, the healthy life can also reduce the risk of disease. Therefore, from the daily diet, sleep, exercise, psychological adjustment, adhere to the health examination, early diagnosis and treatment of disease, you can maximize away from cancer, maintain health.
