    Overnight dishes are well preserved and can be consumed for a certain period of time. As for many overnight dishes, they threaten health and even cause cancer, which is an exaggerated and implausible claim. As for "overnight vegetables cause cancer", everyone says as follows:

    Overnight cooking produces a lot of nitrite, which is a carcinogen, hence the claim. It is true that overnight dishes will produce more nitrite than fresh dishes, but we don't have to be afraid of nitrite levels, which are far beyond the limits of human intake.

    Nitrite is actually a recognized food additive, so it is impossible to say that we will definitely cause cancer after eating some foods with added nitrites. AsiaNitrate is a class of preservatives that prolong the retention time of food and have the effect of increasing the tenderness and freshness of meat. It is often added to processed meat products and canned meat products.

    However, the use of nitrite is strictly controlled because excessive intake of nitrite can lead to acute poisoning and long-term intake of nitrite can lead to cancer.

    So, how much nitrite is in an overnight meal? Many researchers have made relevant statistics. Even if leafy greens that are most likely to produce nitrite (leafy vegetables have a lot of nitrate of their own, which can be turned into nitrite by bacteria over a long period of time, and which react with bacteria in the air after frying, so they are most likely to produce a lot of nitrite in food) are left at room temperature for 20 hours, they produce a hundred times less nitrite than our limited intake, so don't worry about nitrite in overnight dishes that can cause cancer in your body.

    However, there are some things that we need to worry about. If the overnight meal is not stored well, it may spoil, especially in the summer when the temperature is high. If we don't have time to put our morning leftovers in the fridge, they may turn sour in the afternoon.

    In addition, if there are more bacteria, nitrates in food will be more easily reduced to nitrite. Fortunately, bacteria are greatly inhibited at a certain temperature, so as long as they are stored in the refrigerator in time, they are fine

    We often encounter such a situation, when eating at home, because the meal is not finished, parents will often put the meal in the refrigerator and heat it up the next day before eating. These meals became overnight meals the next day. Many people wonder, is it OK to eat overnight dishes?

    Is eating overnight food good for your health? Here are a few points of analysis about overnight dishes.

    1. The effect of overnight dishes on the body.

    1.Overnight dishes can produce a lot of bacteria, and if they are not heated enough when they are eaten overnight, bacterial infections may occur. Various green leafy vegetables contain different amounts of nitrate, nitrate itself is non-toxic, but after the meal is left overnight, bacteria will decompose, and nitrate will decompose into nitrite, which is a carcinogen.

    The nitrite produced by vegetables overnight will cause the hemoglobin and iron in the human body to lose the oxygen synthesis effect, causing tissue hypoxia, and in severe cases, it can lead to death.

    2.Eating overnight dishes regularly can cause gastrointestinal dysfunction and even intestinal cramps. Sometimes symptoms such as abdominal pain, bloating, indigestion, nausea, vomiting, diarrhea and non-formation of stools may occur, as well as damage to the liver and kidneys.

    2. Preservation of overnight dishes.

    1.When hot food suddenly enters a cold environment, the hot air of the food will condense water vapor, which will promote the growth of bacteria, which can cause bacterial infection. Therefore, the food should be put in the refrigerator after it has cooled.

    2.Leftovers can be eaten, but be sure to keep them well. If stored at room temperature, it should not exceed 2 hours at most.

    If you put it in the refrigerator for storage, make sure that the refrigeration temperature is lower than 5 degrees Celsius, and the food that has been in the refrigerator for more than 3 days should be heated once and not eaten again, so as not to have diarrhea, etc.

    3.Try to cover meals with plastic wrap or plastic bags, and seal them in clean containers to avoid cross-contamination of bacteria.

    In addition, it is recommended to heat and heat thoroughly when eating overnight dishes, otherwise it will also be harmful to your health. Overnight dishes can be eaten occasionally by adults, and are not recommended for children in the period of growth and development.

    Overnight dishes are generally not recommended. Because overnight vegetables generally contain nitrate, with the growth of storage time, nitrate will be converted into nitrite with carcinogenic effects, if eaten for a long time, it will cause great harm to the human body and even cause cancer. And overnight vegetables will produce bacteria even if they are refrigerated, and it is easy to eat bad stomach and cause diarrhea if they are not heated, and the nitrite content of general meat dishes is less than that of green leafy vegetables after overnight, but they also need to be heated before eating.

    It is not recommended to eat.

    Overnight dishes are not recommended, especially leafy greens. Even if you save it, it will produce carcinogens, so remember to eat as much as you want next time.

    Here's what you need to know about overnight dishes:

    If the stir-fried vegetables are left for too long or the greens are bought for a long time, the nitrates in the dishes will be reduced to nitrite under the action of bacteria. This nitrite-containing leftovers will not work even if they are placed in the refrigerator.

    Even if the leftovers are taken out and heated, not only can the toxic nitrite not be removed, but the remaining nitrate in the dish will be decomposed into more nitrite under the action of high temperature. After too much nitrite enters the human body and is absorbed into the blood, it can convert the low hemoglobin in the blood into methemoglobin, lose the ability to carry and transport oxygen, and the tissues and organs can not get enough oxygen, and the body will have hypoxia symptoms, and the mild ones will have nausea and vomiting and other discomforts, so it is not recommended to eat green vegetables overnight.

    How much nitrite does overnight greens produce? When vegetables are heated and the high temperature inactivates the reductase enzyme and kills most bacteria, it is the healthiest to eat. Cooked vegetables are more suitable for bacterial growth, even if they are covered with plastic wrap and put in the refrigerator, they will let bacteria in when they are taken or turned, so that the nitrite content will start to increase again.

    Generally, after 24 hours of storage in the refrigerator, the nitrite content of vegetables is about 7 kg. All kinds of green leafy vegetables contain different amounts of nitrate, especially nowadays with a large use of chemical fertilizers, resulting in an increase in nitrate content in vegetables, so this situation is not recommended to eat.

    Can you not eat overnight dishes, and will it have a negative impact on human health?

    Overnight vegetables generally contain nitrate, and with the increase of storage time, nitrate will be converted into nitrite with carcinogenic effects, which will cause great harm to the human body and even cause cancer if eaten for a long time. There are a lot of bacteria, insect eggs, etc. in the overnight dish, which can easily cause physical diseases after eating. Overnight dishes will lose nutrients, or eating fresh meals is better for your health.

    Secondly, when the overnight meal is repeatedly heated, a carcinogen called nitrite will be produced in the meal, which will increase the risk of cancer in the human body after being consumed.

    In our daily life, it is inevitable that there will be leftovers from meals, if you want to eat less overnight meals in your life, you must pay attention to the amount of food when stir-frying, and try to eat every meal without leftovers. Generally speaking, leftovers will deteriorate in 4 hours at room temperature, and spoiled in 2 hours when the temperature is high, so it is best to heat up overnight meals before eating.

    Occasional leftovers have no effect on our health, but long-term leftovers will definitely damage our body.

    The so-called carcinogenicity, nitrite acid, is a degree of problem, you say that the exhaust gas you inhale in the city is not carcinogenic? Does radiation from your home computer cause cancer? Do you guarantee that the dishes you eat are all natural and green foods?

    Even if you go to the Qinghai-Tibet Plateau, the food is all natural, no exhaust gas, no radiation, but the thin air and ultraviolet rays can still cause cancer.

    Dangers of overnight dishes:

    According to scientific determination, some overnight vegetables, especially overnight green leafy vegetables, not only have low nutritional value, but also produce disease-causing nitrite. The amount of nitrite in stored vegetables increased with the extension of storage time and the increase of temperature, while the increase of nitrite was less if the vegetables were refrigerated in the refrigerator (2-6 degrees Celsius). Overnight dishes.

    It's winter, and some families think that the weather is cold and leftovers don't need to be put in the refrigerator, which is also wrong. Now, the widespread use of refrigerators in cities has reduced the nitrite content of people's intake from food, but it does not mean that vegetables can be put in the refrigerator with complete confidence; Over time, the nitrite content will still increase. It is worth mentioning that the amount of nitrite produced by different types of vegetables under the same storage conditions is not consistent.

    In general, stem and leaf vegetables are the highest, melon vegetables are slightly lower, and root and cauliflower vegetables are in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat stems and leaves first, such as Chinese cabbage, spinach, etc. If you are going to cook more vegetables and eat them hot the next day, you should try to make less stem and leaf vegetables and choose melon vegetables.

    There is oil and salt in the fried dish, and after one night, the vitamins in the dish are oxidized, which greatly increases the nitrite content, and becomes nitrite after entering the stomach, although nitrate is not a direct carcinogen, but it is a major hidden danger to health. After nitrite enters the stomach, it produces a substance called NC (N-nitroso compound) when certain conditions are met, which is one of the risk factors for gastric cancer. Especially when the weather is hot, overnight meals are contaminated with bacteria and can multiply in large numbers, which can easily cause gastroenteritis and food poisoning.

    Many fresh vegetables and meat contain nitrate, but if left at room temperature for too long, bacteria can easily grow, and the nitrate in the food will be reduced to nitrite under the action of bacteria. Nitrite is a toxic substance.

    In many cases, the cooking at home will cook more, the vast majority of people keep this kind of leftovers, and wait for the next time they eat to heat it up, especially the elderly, feel that if the leftovers are thrown away, they will be consumed, and they are very reluctant, so it is generally not easy to throw them away, but in fact, long-term eating leftovers has an impact.

    There will be a lot of germs and viruses in the remaining ingredients, and after eating, this bacteria and viruses will be brought into the stomach, so the stomach and intestines will be damaged, and some diseases will be obtained, and the plot is milder is diarrhea or severe constipation, and more serious ones will have colitis or gastritis, etc., of course, the damage to the stomach and intestines is particularly large, so it is better to put leftovers for a long time or do not have to eat, so that you can maintain the stomach and intestines.

    Leftovers are often not eaten because they contain a lot of nitrite, which is also a harmful ingredient, and if there is too much nitrite in the body, it can cause death. There are a lot of nitrite poisoning news reports in daily life, nitrite damage to the body is very large, but in order to better make the shelf life longer, many ingredients also have nitrite in them, only the nitrite composition here can not be too high, it must be produced after inspection, everyone's daily leftovers also have nitrite, especially some vegetables and fruits, so the remaining vegetables and fruits are definitely not left to eat a second time, Everyone must remember.

    Although the carcinogens of overnight dishes are a kind of indiscriminate transmission, but try not to take overnight dishes, because the problem of overnight dishes is that the nutrients are damaged, such as vitamin C in the ingredients, vitamin C itself is more afraid of high fever, and the process of cooking vegetables has already been damaged by about 30%. And overnight dishes will produce some microbial strains and germs, which are very bad for the body and can easily cause gastrointestinal inflammation, so try to eat as much as you want, and don't have leftovers.
