Improperly preserved food is prone to bacterial growth
Is it possible to put a night's worth of food on the table? Some experts say that overnight food refers to all the food stored for several hours, food storage will be due to improper preservation or food deterioration of bacteria breeding problems. The best thing to do is to eat the food right away, otherwise the bacteria will overpopulate the food and cause gastrointestinal discomfort, diarrhea and vomiting.
Food preserved for a few hours will produce nitrite
As for food spoilage, some scholars measured by experiments, the longer the food shelved, which generates more nitrite, including greens, fish, meat, eggs, etc., preserved for a few hours after the nitrite will be produced. Nitrite derivatives are one of the carcinogens of the gastrointestinal tract, and overnight dishes are carcinogenic.
However, nitrite derivatives are not only found in overnight vegetables, but also in processed meats and smoked or cured foods, such as sauerkraut, pickles, sauerkraut, sausages, hot dogs, bacon, salted fish, smoked meats, etc., which are all recommended to be avoided as much as possible.
Prepare a meal portion
Colorectal cancer factors include genes, diet, environment and other factors, such as a family history of colorectal cancer, as well as dietary habits of Westernization, including love of red meat, high-fat and low vegetables and fruits fiber, etc., which have been proven to be cancer-causing factors. Therefore, although it is uncertain whether overnight food is the main cause of colorectal cancer, it is recommended to eat a balanced diet, do not prefer meat, consume enough fiber; choose more fresh food, reduce the consumption of processed food; prepare food is best not left over, to avoid improper preservation of food and affect the health.
"Overnight food is high in nitrites! Eating it causes cancer! You can't eat it!" "Who said! As long as you heat it up, you can eat it!" "It is said that overnight vegetable leaves can not be eaten, meat can be!" In fact, none of these statements are completely correct.
To correctly recognize the overnight vegetables, first of all, we have to understand the "overnight vegetables such as arsenic" what is going on. People often say in the mouth of the food class arsenic refers to nitrite, food in the production of nitrite and other harmful substances in the end is not the reason for overnight? And the way of storage and what is the relationship?
In fact, food in the storage process because of bacterial activity, may be the original presence of nitrates in the vegetables, into the nitrites, nitrites itself is not a problem, just in the stomach may be reduced to nitrosamines, is a strong carcinogen. There are two main ways to produce nitrite: 1. In the process of eating, there will be some bacteria on the chopsticks into the leftover vegetables. 2. 2. During the preservation process, some airborne bacteria may also enter. Cooked vegetables are better suited for bacterial growth, and they will grow in abundance under the right conditions.
So what is the proper way to handle overnight vegetables?
Leftovers in the refrigerator in time
No matter what kind of food, the longer it is left at room temperature, the more microorganisms multiply and the more unsafe it is. So the people usually think of the dish cooled and then put into the refrigerator, in fact, is not correct, put into the refrigerator, the speed of cooling is also very important. If the refrigerator is too full of things, the cooling effect is not enough, or the dish is too big, put a long time are difficult to cool down, will also bring security risks.
It's important to divide the food ahead of time
If you know you won't be able to finish the meal, you should divide the food into different dishes and put it in the fridge when it cools down a bit. This way, there is less bacteria in the dish, and there is no problem to eat it the next day or even the third day when it is warmed up, so don't pack it after you finish it.
Clever use of plastic wrap, plastic box
Leftovers in the refrigerator before, be sure to use plastic wrap sealed, or into a plastic box with a lid, to avoid airborne bacteria as well as crosstalk and cross-pollution.
Overnight dishes, be sure to heat through
Leftovers can be eaten, but only if they are thoroughly heated. If the meat is larger, be sure to boil or steam it longer, or chop it up and reheat it. If you use the microwave oven to heat the leftovers, pay special attention, microwave heating is easy to heat unevenly, it is likely that this part of the food has been very hot, the other part is still cool. You can first microwave for a minute or two, so that the internal temperature of the food rises, and then use the pot to heat, or then put the steamer on the steamer, it is easier to heat through.
Although overnight food can be eaten, but for the sake of our health, it is still recommended to eat less overnight food, promote CD-ROM action.
Of course, don't force yourself to eat all the leftovers for fear of wasting them. Extra food will bring a heavy burden to the body, may lead to obesity, acute gastroenteritis, etc., the loss is not worth it.
Preparing ingredients on demand and avoiding bacterial contamination is the solution.
Don't talk a good game and exaggerate. As long as it's not scrambled eggs or fish, overnight vegetables are not as dangerous as claimed. The real cancer culprits are smoked barbecue and moldy food, such as moldy soybeans, peanuts, corn, and macerated yellow rice processed rice, because they all contain a large number of carcinogens: aflatoxin. For example, unscrupulous merchants sell rice looks white as jade shiny, but the price is not expensive. Unbeknownst to these rice may be composted yellow rice after special processing shifted into a good rice, so that people unknowingly planted the root of the problem. Overnight vegetables as a cancer culprit is not reliable. As long as the fresh vegetables, chicken, duck, fish and meat, cooked in a reasonable way stir-fried dishes, in the case of not eaten in the refrigerator the next day to eat will not have any problem. The real enemy of cancer is our living environment, lifestyle, product quality and the degree of food and drug safety and so on.
Leftovers boldly eat, say can not be eaten, to cause cancer are fart, practice has shown that my neighborhood 97-year-old Zhu Shengrong grandfather ate more than 90 years of overnight dishes, the next few nights of food to eat, and Zhu Gui'e old lady is now 88 years old, ate more than 80 years of overnight meals, young life is bitter, the vulnerability of vulnerable rice vulnerability will not be able to get poured out, are often eaten, as well as Zhou Xiaobao, Zhu Shengquan is 90 years old, leftovers! Leftovers as usual, these four people are now healthy, housework as usual, they are four people in a neighborhood, now life is, because the night son in law grandchildren at home, burn more meals, eat the rest of the son in law tomorrow grandchildren are gone, the old man ate leftovers, day in and day out, often this way of life, the body is very good, please those who say that leftovers can not be eaten, come over to the investigation and then speak.
Hello. Thank you for letting me answer you this question. You this question is equal to say a topic two Q&A. Then I'll talk about overnight dishes repeated heating is a cancer culprit? First of all, the overnight food processing is not good will indeed produce carcinogenic amine nitrite, but overnight food heating is not necessarily a cancer culprit, because cancer is the formation of a variety of factors, and then heated overnight food is not a lot of food is not many, in the many times repeated heating, many times repeated eating it. There are so many carcinogenic substances for normal people will not cause the occurrence of cancer. Of course, with the enhancement of people's health awareness and attention, if the consumption of overnight food is still not assured, you can also fry vegetables in the process of not putting salt, vegetables fried and sheng out only enough for this amount of food, this part of the dish into the appropriate salt to be eaten at one time, the rest of that one did not add salt to the dish with a cooled down sheng into a clean bowl and plate, best to seal with plastic wrap, put into the refrigerator, and so on, you next time you eat when heated up and then Add the right amount of salt can be, this not only reduces the waste and isolate the amine nitrite and reduce the production of cancer.
Speaking of leftovers how to deal with the better just now has spoken of not adding salt to the portion, the following I say again has added salt to eat after the leftovers, how to deal with, if only from the pursuit of absolute health aspects, then it is very simple, then you will be poured out. If you want to consider health but do not want to be extravagant and wasteful, there are no special requirements for your health, and if you don't have too much left over, you will be able to finish it the next time or the second time you eat it. If you have too much left over, you can finish it the next time or the second time, then you should eat it without worry, because as I said just now, although cancer is scary, it is not something that can be caused by any one factor alone. Do not say leftovers, is the geography is growing vegetables itself contains nitrites, we do not have to worry too much about this, because emotional depression is also one of the factors of cancer, if you put a good mood, are overly worried about the vegetables in the three meals a day, in the long run you that the body is not as good as that often eaten leftovers of the body of the people it . So don't be so absolutely good at everything. A good mood is also a good medicine. I hope my answer can help you. Thank you Goodbye
Why is this? I think it may be that the environment is different now, because the problem of environmental pollution, it is all the trouble caused by environmental pollution.
Repeated reheating of overnight dishes is a cancer-causing culprit? This is too exaggerated and sensationalized. (I still warmed up last night's leftovers for breakfast today.) I certainly know that eating overnight meals is not good, but the fresher the food, the better (except for special flavors such as curd, stinky tofu, stinky Mandarin fish; all kinds of pickles, pickles, and so on; and a small number of people love to eat a little bit of stinky pork)?
However, the Chinese people have the virtue of thrift and diligence since ancient times; "The day of the hoe is the afternoon, the sweat drops under the soil." Food is not easy to come by, waste is shameful, I can only will be leftovers hot, make do and eat ah, otherwise, what a pity ah. Not to eat some leftovers on the cancer, right, the original time there is no refrigerator, are not all so eat? At that time, except for the special reasons in special times, people ate less and wore less, and starved to death and froze to death, but there were not more cancer patients than people nowadays! Nowadays, there are many more cancer patients. (Not to mention, that is, egg fried rice, but also have to be used overnight leftovers to fry, to be good.)
So, I personally don't think that eating some leftovers will necessarily be how. It's not a bad idea to do it once in a while. In other words, the nitrites contained in leftovers, in many foods, in fact, is more or less, the same presence. It's just that fresh vegetables and fruits and so on are generally better and contain less nitrites. But in some unique food, nitrite will be more, for example, bacon, sausage, bacon chicken, bacon fish, bacon, ham, hot dogs, and all kinds of kimchi, pickles, curd, stinky tofu, etc. (How many of these popular food, and how many of them are not? (How many people have never eaten any of these popular foods?) Therefore, there is no need for us to talk about "nitrites", as long as we do not regularly consume these non-mainstream foods, but only eat them occasionally, there is no need to suffer. Besides, how many of the rich people for the rich, meals of big fish, meat, delicacies, only eat the most fresh, do not dip into the leftovers, but still all kinds of cancer as usual? The first thing you need to do is to get a good deal of money from the government.
The leftovers, naturally, should be heated up and eaten, so it is good. Otherwise, do not have to eat the remnants of cold rice not? After all, overnight dishes, may have been more nitrites, bacteria also multiply, heating this step, or can not be saved. Besides, who, full of support, nothing will go to the leftovers, repeated multiple heating it? The first thing you need to do is to get your hands dirty and get out of the way.
Leftovers, previously in the cabinet, to prevent cats and dogs, insects and ants contamination; do not cover tightly, in order to facilitate the ventilation of air deterioration; now, there is a refrigerator, you can use plastic wrap wrapped up in the refrigerator refrigerator to preserve freshness is better.
In the past, when life was difficult, leftovers could not throw away, a ton or two tons to eat did not see a few cancer, and now the word is good, always afraid of cancer, which do not eat that can not eat, cancer is more and more, in fact, people want to damn what also when not, is to eat a good meal eat more. The leftovers are less to do enough to eat on the line, big fish and meat left frozen, eat again when hot.
Don't be alarmist. Overnight food is not conducive to the health of the human body bacteria and nitrites, but the human body itself is immune, enough to eliminate these bad things, the human body is in the fight against these harmful bacteria and other bad things to get healthy. Too pure, deliberate life, but make people lose resistance. The original I know a section-level cadres, to eat things really too hygienic, have cleanliness, as a result, people get thin bones, face without red, and soon left the world. Overnight dishes can be eaten without heating, some to heat to eat, which is also appropriate for the dish. The key is to keep the edible overnight vegetables well. We use the refrigerator box at home or cleaning film sealed in the refrigerator storage, the next day, as long as it does not deteriorate and change the flavor can be eaten without fear. Of course, to be on the safe side, eat less. Now, we pay more attention to food hygiene, buy food to do just the right portion, eat the meal. Sometimes due to changes in the number of diners or guests, burned dishes have leftovers, which is normal. Some suffer from the impact of eating overnight food will cause cancer, will be able to eat the overnight food dumped, which is also a waste. In fact, as long as the safekeeping storage method, eat is no problem.
