On the other hand, it is difficult for fish and seafood heated by microwave oven to maintain their original color and flavor, which will also affect their appetite from the appearance. It is not advisable to bring green leafy vegetables. Green leafy vegetables contain different amounts of nitrate. If they are heated or stored in a microwave oven for too long, the vegetables will turn yellow and taste bad, and nitrate will be reduced to toxic nitrite by bacteria, which will cause cancer.
It is also inappropriate to bring cold salad. The key is that cold salad should not be eaten overnight. Cold salad is polluted when it is processed. Even if it is refrigerated, it is likely to deteriorate after overnight, so it is not worth putting it into the lunch box overnight. In particular, it is not advisable to bring foods with high oil content. It is best not to bring Sichuan style pork, sweet and sour pork ribs, patties and fried rice, because they contain too much oil, and these things are more likely to deteriorate and not easy to keep fresh.
The cooking methods suitable for microwave oven heating are steaming, braising and stewing. The dishes cooked by these methods are not easy to taste and change color after microwave oven heating, while the dishes fried and stir-fried are obviously not suitable for microwave oven heating. In addition, compared with green vegetables, eggplant vegetables are not easy to deteriorate, and it is not easy to change the color and fragrance of dishes after microwave heating. Need to remind you that the vegetables you want to bring should be fried until six or seven minutes are cooked, so as to prevent further damage to its nutrients when heated by microwave. Classic dishes, such as scrambled eggs with tomatoes and roasted eggplant, are more suitable for the "family with rice".
Question 2: What dishes can't be eaten overnight ~ According to scientific determination, some overnight dishes, especially overnight green leafy vegetables, not only have low nutritional value, but also produce pathogenic nitrite. The amount of nitrite produced in stored vegetables increases with the increase of storage time and temperature, but if vegetables are stored in refrigerator (2-6 degrees Celsius), the increase of nitrite is less. It's winter, and some families think that it's cold and leftovers don't need to be put in the refrigerator. This view is also wrong. Now, the widespread use of refrigerators in cities has reduced the nitrite content people consume from food, but it does not mean that putting vegetables in the refrigerator can be completely reassuring; After a long time, the nitrite content will still increase. It is worth mentioning that different kinds of vegetables produce different amounts of nitrite under the same storage conditions. Usually, stem and leaf vegetables are the highest, melon vegetables are slightly lower, and roots and cauliflowers 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 and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.
After frying, there is oil and salt in the dish. After a night, the vitamins in the dish are oxidized, which greatly increases the content of nitrite and turns into nitrite after entering the stomach. Although nitrate is not a direct carcinogen, it is a big health hazard. After nitrite enters the stomach, it will produce a substance called NC (N-nitroso compound) under certain conditions, which is one of the risk factors of gastric cancer. Especially in hot weather, overnight meals are contaminated by bacteria, which will multiply and easily lead to gastroenteritis and food poisoning.
Many fried dishes can't be eaten and stored, especially some high-protein and high-fat leftovers, which are even more inedible. Harmful bacteria in the air will attach to the leftovers within 2 hours and start to reproduce. As we all know, most of protein and fat will produce harmful substances under the action of bacteria, such as hydrogen sulfide, amines, phenol, etc., which are harmful to human body. It is an indisputable fact that eating leftovers for a long time is easy to cause cancer. Therefore, you can't eat overnight dishes. When cooking, the best way is to tailor your clothes, not to harm your health!
Chinese cabbage is a vegetable that people often eat, and it is known as the king of vegetables. Cabbage contains nutrients such as iron, calcium, phosphorus and vitamin C, which are of great benefit to the human body. Therefore, many people use it not only for cooking and stuffing, but also for making soup. However, the soup made on the same day must be finished on the same day, and it is not advisable to drink cabbage soup overnight. This is because Chinese cabbage is rich in nitrates. If Chinese cabbage is cooked for too long, nitrates will react chemically under the action of some bacteria and be reduced to nitrite. Nitrite is easily dissolved in vegetable soup, and people will enter the gastrointestinal tract and blood with the vegetable soup after drinking it.
There is hemoglobin in the red blood cells in the blood, which can carry a lot of oxygen for the body's needs. After nitrite enters the blood, even the normal hemoglobin is oxidized into methemoglobin, thus losing the ability to carry oxygen, causing the body to suffer from lack of oxygen, causing cyanosis and cyanosis of the skin and mucous membrane, and in severe cases, causing death. Therefore, cabbage tastes good in soup, but it should not be eaten overnight. In order to prevent nitrite poisoning, adding vinegar during cooking can destroy the formation of nitrite.
Cabbage:
Pay attention to the inappropriateness when eating Chinese cabbage.
Generally speaking, Chinese cabbage should be fried and eaten now, not cooked overnight; Pickled cabbage should be marinated thoroughly, washed and fried before eating. Why? ?
Fresh Chinese cabbage contains a lot of sterile nitrate, which is reduced to nitrite due to the action of bacteria when it is left for a long time before being marinated or cooked. After nitrite is ingested into the gastrointestinal tract, it quickly enters the blood, which oxidizes the low-iron hemoglobin in the blood and turns it into methemoglobin, thus losing the ability to carry oxygen, resulting in poisoning of the body due to lack of oxygen, ranging from dizziness, headache, nausea and vomiting, abdominal pain and abdominal distension, to cyanosis and cyanosis of the skin and mucous membrane, and even coma and convulsion, which seriously harms human health.
Tomatoes:
When eating tomatoes, we should pay attention to the inadvisability.
First, it is not appropriate to eat tomatoes in large quantities on an empty stomach: the secretion of gastric acid on an empty stomach is increasing, and tomatoes contain a large number of ingredients such as carbuncle, fruit, persimmon carbinol and soluble heart-collecting agent, which are easy to combine with gastric acid to form insoluble massive stones, block the pyloric outlet of the stomach, increase the pressure in the stomach, and cause stomach discomfort and flatulence. ?
Second, it is not suitable to eat cyan immature tomatoes: this is because the immature cyan tomatoes contain solanine, which makes people bitter in the mouth and uncomfortable in the stomach cavity after eating, which can seriously lead to poisoning.
Ginger:
The inadvisability of eating ginger in summer
Summer heat makes most people lose their appetite. Ginger spicy in fresh ginger ... > >
Question 3: Five kinds of overnight dishes can't be eaten around us. Some friends like to leave the food they can't finish until the next day. However, this practice is very undesirable. Overnight dishes not only destroy their nutritional value, but also produce pathogenic nitrite.
The following five dishes can't be eaten overnight.
1, green leafy vegetables are the most dangerous overnight.
Usually, the nitrite content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, and the roots and cauliflowers are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables first, such as Chinese cabbage and spinach. If you plan to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.
2. Overnight seafood damages liver and kidney.
Seafood such as crabs, fish and shrimps will produce protein degradation products overnight, which will damage the liver and kidney function. If you really buy too much, you can pack raw seafood in fresh-keeping bags or boxes, freeze it in the refrigerator and cook it next time.
3. Half-boiled eggs are easy to cause diseases.
Many people like to eat soft-boiled eggs, but this kind of eggs is not completely sterilized. In addition, the eggs are rich in nutrition, which is particularly easy to breed bacteria, and it will be dangerous after eating. If the eggs are ripe and properly sealed at low temperature, it is no problem to eat them overnight.
4, tremella mushrooms should be careful
No matter wild or cultivated tremella, mushrooms, etc., it is easy to leave a lot of nitrate. If it is left for a long time, it can only be reluctantly thrown away.
5. Don't put soup in metal utensils.
Boiling soup is time-consuming and laborious. People often boil a large pot and eat it for several days in a row. If the leftover soup is kept in a aluminum pot or an iron pot for a long time, it will precipitate substances harmful to human body. The best way to save soup is not to put seasonings such as salt in it. When the soup is cooked, use a clean spoon to drink it that day. If it can't be finished, it is best to store it in the refrigerator with a earthenware pot or a fresh-keeping box.
The Chinese nation has a fine traditional virtue, that is, it doesn't waste food. Many people are used to saving leftovers for the next day. However, if some foods are eaten overnight, they may be harmful to health. The following China Eating Network has compiled information about what dishes can't be eaten overnight, which needs your attention.
1, overnight leafy vegetables
Because some green leafy vegetables contain more nitrates, if they are cooked for too long, they will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating. Healthy eating method: usually, the nitrate content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, and the roots and cauliflowers are in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat stem and leaf vegetables first, such as Chinese cabbage and spinach.
2, overnight tea
Overnight tea has lost most of its vitamins for a long time, and protein and sugar in tea soup will become nutrients for the reproduction of bacteria and molds. Therefore, people usually think that overnight tea can't be drunk.
3. Overnight soup
Cantonese people like to make soup, and put it in the refrigerator until it is boiled the next day. Is this kind of overnight soup good for your health? How to eat it healthily: The best way to preserve it is to spoon out the soup you want to drink that day with a clean spoon, and it is best to store it in the refrigerator with a earthenware pot. Because the leftover soup is kept in aluminum pot and stainless steel pot for a long time, it is prone to chemical reactions and should be placed in glass or glass.
4. Seafood
Overnight foods that should not be eaten include fish, seafood, green leafy vegetables and cold salad.
Fish and seafood are prone to produce protein degradation products overnight, which will damage liver and kidney function.
Containing different amounts of nitrate, if cooked too much or left for too long, not only will vegetables turn yellow and taste bad, but nitrate will also be reduced to toxic nitrite by bacteria, which has carcinogenic effect. Cold salad is polluted when it is processed, even if it is refrigerated overnight, it is likely to deteriorate, so it should be made and eaten now.
5, family pot-stewed bad goods
Pot-stewed food and bad food are both popular seasonal dishes in Shanghai. Many residents also like to put the leftover pot-stewed bad food in the refrigerator for the night, but this has great food safety hazards. To prevent food poisoning, don't eat pot-stewed bad food overnight in spring and summer.
Bulk pot-stewed meat should be eaten on the same day, not overnight. From the perspective of food safety, it is unsanitary. If possible, it is best not to eat bad goods overnight. Food experts remind that even food stored in the refrigerator is not absolutely "safe". The refrigerator is prone to mold and psychrophilic bacteria.
6. Eggs overnight
If the eggs are not completely cooked, the immature yolk will be eaten overnight, and under the condition of improper preservation, the nutritious things will easily breed bacteria, resulting in ...... >; >
Question 4: Why do people say that overnight dishes can't be eaten and meat can be eaten? According to scientific determination, some overnight vegetables, especially overnight green leafy vegetables, not only have low nutritional value, but also produce pathogenic nitrite. The amount of nitrite produced in stored vegetables increases with the increase of storage time and temperature, but if vegetables are stored in refrigerator (2-6 degrees Celsius), the increase of nitrite is less.
Under the same storage conditions, different kinds of vegetables produce different amounts of nitrite. Usually, stem and leaf vegetables are the highest, melon vegetables are slightly lower, and roots and cauliflowers 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 and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.
After frying, there is oil and salt in the dish. After a night, the vitamins in the dish are oxidized, which greatly increases the content of nitrite and turns into nitrite after entering the stomach. Although nitrate is not a direct carcinogen, it is a big health hazard.

It is an indisputable fact that eating leftovers for a long time is easy to cause cancer. Therefore, you can't eat overnight dishes. When cooking, the best way is to tailor your clothes, not to harm your health!
As for overnight meat, you can't eat it in mild weather, but there should be no problem if it is cold.
Question 5: What overnight dishes should you never eat "overnight dishes"? It doesn't just refer to dishes left overnight. If they are left for more than 8-10 hours, they should be considered overnight. There are two reasons for the increase of toxic components in food. The first reason is that chemicals in food produce carcinogens, such as nitrite, which cannot be removed even if heated. Another reason is the secondary pollution caused by foreign bacteria when it is placed. The following kinds of dishes are particularly harmful if left for a long time.
Green leafy vegetables are most dangerous overnight. Usually, the nitrate content of stem and leaf vegetables is the highest, melon vegetables are slightly lower, and roots and cauliflowers are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables, such as Chinese cabbage and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.
Overnight seafood damages liver and kidney. Seafood such as crabs, fish and shrimps will produce protein degradation products overnight, which will damage the liver and kidney function. If you really buy too much, you can pack raw seafood in fresh-keeping bags or boxes, freeze it in the refrigerator and cook it next time.
Soft-boiled eggs are easy to cause disease. Many people like to eat soft-boiled eggs, but this kind of eggs is not completely sterilized, and the eggs are rich in nutrition, which is particularly easy to breed bacteria and will be dangerous after eating. If the eggs are ripe and well preserved in a low-temperature seal, it is no problem to eat them overnight.
Beware of tremella mushrooms. Whether it is wild or cultivated tremella, mushrooms, etc., it is easy to leave a lot of nitrate. If you leave it for a long time, you can only reluctantly throw it away.
Don't put the soup in the metal container. Boiling soup is time-consuming and laborious. People often boil a large pot and eat it for several days in a row. If the leftover soup is kept in aluminum pot and iron pot for a long time, it will precipitate substances harmful to human body. The best way to store soup is not to put seasonings such as salt in the soup. When the soup is cooked, use a clean spoon to put out what you want to drink that day, and it is best to store it in the refrigerator with a earthen pot or a fresh-keeping box.
Question 6: What cooked vegetables can't be eaten overnight?
Thrift is the traditional virtue of China people, so it seems to be a common thing to eat overnight dishes. As everyone knows, overnight dishes not only lose nutrients seriously, but also produce substances that are harmful to the health. Fang Shi, director of the Nutrition Department of the First Affiliated Hospital of Sun Yat-sen University, reminded that vegetables and seafood should not be eaten overnight, and meat must be steamed and cooked thoroughly to prevent food from being stored for a long time, rotting and deteriorating, leading to food poisoning.
Overnight leafy vegetables should not be eaten.
It is said that the low incidence of gastric cancer in Guangdong is related to the habit of not eating vegetables overnight. Because some green leafy vegetables contain more nitrates, if they are left for too long after cooking, nitrates will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating.
Healthy eating: Generally, the nitrate content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, and the roots and cauliflowers 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 and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.
Overnight soup storage is exquisite.
People in Guangzhou like to make soup, put the soup in the refrigerator and boil it the next day before drinking it. Is this overnight soup good for your health?
Healthy eating: The best way to preserve the soup base is not to put seasonings such as salt. When the soup is cooked, scoop out what you want to drink that day with a clean spoon, and it is best to store it in the refrigerator with a earthen pot. Because the leftover soup is stored in aluminum pot and stainless steel pot for a long time, it is prone to chemical reaction, so it should be kept in glass or ceramic utensils.
Bring your own lunch should have a choice.
Many people are tired of eating lunch boxes in restaurants and don't want to fight guerrilla warfare outside, so they choose to bring their own lunch. However, most of the meals brought with you are the meals of the night before. After one night and one morning's storage, the nutrition loss in the food is more serious, so when you bring your own meals, you should also choose.
Healthy eating: You can bring your own food such as rice, beef, bean products, various non-green vegetables, fruits, yogurt and so on.
To ensure sufficient energy for lunch, foods containing protein, vitamins and minerals are essential. Among vegetables, loofah and lotus root contain more cellulose. In addition, you can also choose celery, mushrooms, radishes and so on. Just stir-fry the vegetables you want to bring for six or seven minutes when cooking, so as to prevent further damage to their nutrients when microwave heating the next day. Try to choose meat dishes with less fat, such as beef and chicken. After cooking, cover it immediately after cooling and store it in the refrigerator at 4℃. Take it to the office the next day and put it in the refrigerator immediately. At lunch, fully heat it in the microwave oven and eat it.
Overnight foods that should not be eaten include fish, seafood, green leafy vegetables, cold salad and so on. Fish and seafood are prone to produce protein degradation products overnight, which will damage the liver and kidney function. Green leafy vegetables contain different amounts of nitrate. If they are overcooked or left for a long time, not only will the vegetables turn yellow and taste bad, but nitrate will also be reduced to toxic nitrite by bacteria, which will cause cancer. Cold salad is polluted when it is processed, even if it is refrigerated, it is likely to have deteriorated after overnight, so it should be made and eaten now.
Question 7: What should I do if I have to eat overnight meals? What kind of food must not be eaten overnight? As for food hygiene, it's nothing, as long as it doesn't go bad, you can eat it, and you should pay attention to packaging. First, don't put it in an airtight place. Second, don't use that kind of foam box, try to use porcelain bowls. Third: when the weather is too hot, the lid must be opened, but put a paper towel on it, which depends on your preference. Some people don't like it, but some people don't care, as long as it doesn't spoil, and you are the third kind of person, and you can't help eating overnight meals. I've only heard of drinking tea and trying not to drink overnight tea, but I've never heard of people who can't eat overnight meals. Don't worry.
Question 8: What dishes can't be eaten overnight? Eight kinds of dishes can't be eaten overnight. Some dishes in daily life can't be eaten overnight. So, which dishes can't be eaten overnight? Let me introduce eight kinds of dishes that can't be eaten overnight. Let's find out.
The following eight dishes can't be eaten overnight:
Half-baked eggs
Nowadays, many fashionable cheese people like to eat half-cooked eggs, thinking that semi-liquid eggs that are not fully cooked will not destroy their nutrients, but in fact, raw eggs contain many bacteria and viruses, and in fact, the nutrients of cooked eggs and half-cooked eggs will not be much different. Moreover, eating half-baked eggs overnight is particularly easy to breed bacteria, causing gastrointestinal discomfort and flatulence.
Some people say that tea eggs are cooked the day before and sold overnight. However, the tea eggs were cooked twice in the production process, first cooked, and then the eggshells were broken and boiled with various auxiliary materials such as tea. If it is a well-cooked egg, it can be eaten overnight if it is properly preserved in a low-temperature seal!
Overnight leafy vegetables
It is best to finish the dishes of the day, and don't leave them for the next day. Even if there is no "hue", these overnight green leafy vegetables not only have no nutrients, but also produce pathogenic nitrite. Although the content of nitrite will be reduced when stored in the refrigerator, the content of nitrite will still increase over time. Under the same storage conditions, different vegetables produce the most nitrite, while melons are slightly lower, and rhizomes and cauliflowers are in the middle. Therefore, if you buy vegetables and store them at home, you should eat stems and leaves first, such as spinach and cabbage.
leftover tea from the previous day
Overnight tea has lost most of its vitamins for a long time, and the protein substances and sugars in tea soup will become nutrients for the reproduction of bacteria and molds. Therefore, people generally think that overnight tea can't be drunk.
Household pot-stewed bad goods
Pot-stewed food and bad food are both popular seasonal dishes in Shanghai, and many citizens also like to put the leftover pot-stewed bad food in the refrigerator for the night, but this method has great food safety hazards. To prevent food poisoning, don't eat braised bad goods overnight in spring and summer.
Bulk pot-stewed meat should be eaten on the same day, not overnight. From the perspective of food safety, this is unsanitary. If possible, it is best not to eat bad goods overnight. Food professionals remind that even food in the refrigerator does not have to be "insured". The refrigerator is easy to breed mold, as well as psychrophilic bacteria.
Overnight soup
Southerners like soup very much, especially Cantonese, who are famous for their love of making soup. Put the soup you can't finish in the refrigerator, boil it the next day, and you can cook great noodles with the soup carefully cooked the day before. However, the cheese makers should pay attention to the preservation method of overnight soup. First, when the soup is just cooked, use a clean and unpolluted spoon, and then put the seasoning. If you can't finish drinking it, you should choose to put it in the refrigerator with crock, glass or ceramic utensils, especially aluminum pot and stainless steel pot, otherwise it will easily produce chemical reactions, which is not conducive to your health.
Tremella fuciformis
Theoretically, all foods with high nutrient value should not be eaten overnight, and it is easy to become a hotbed for bacteria to breed, not to mention the reduction of nutrient components. The same is true of tremella fuciformis soup. Both the tremella fuciformis cultivated indoors and the tremella fuciformis cultivated in the wild contain a lot of nitrate. After cooking and bacterial decomposition, the nitrate will be reduced to nitrite. If you drink it on the same day, nitrous acid can naturally enter the blood circulation. There are hemoglobin in the red blood cells in the blood, which can carry a lot of oxygen for the body's requirements. However, overnight tremella will make nitrous acid react, make normal hemoglobin in human body oxidized to methemoglobin, lose the ability to carry oxygen, and cause human body to lack normal hematopoietic function.
Overnight boiling water
Boil tap water for 3 ~ 5 minutes, the content of harmful substances such as nitrite and chloride is the lowest, which is most suitable for people to drink.
Although the boiled water has been cooked thoroughly, it is recommended to drink less boiled water overnight, because nitrite can form carcinogenic nitrosamines in human body. Some professionals have found that the nitrite content in boiled water is higher than that in raw water. Moreover, the content of nitrite increased significantly after repeated boiling for too long or more than 24 hours. After standing in boiling water for 24 hours, the nitrite content is 1.3 times that of when it was just boiled. Chinese residents have the habit of drinking boiled water. It is best to burn it now or drink only the boiled water of the day, and don't drink boiled water for too long. Article source: Qili Women's Network > >
Question 9: Which overnight dishes can't be eaten 1, and can I eat overnight eggs? Northerner: Yes, I can't see that tea eggs are sold on the street! Southerners: No, especially men, because they will get intestinal gas/scrotum swelling. Scientist: Not necessarily! Because if the eggs are not fully cooked, the immature yolk will be eaten overnight. In the case of improper preservation, nutritious things are easy to breed bacteria, which will be harmful to health, such as: causing gastrointestinal problems ... 4. Can tremella be eaten overnight? Auricularia auricula soup is a kind of advanced nutritional supplement, but after overnight, the nutritional components will be reduced and harmful components will be produced. Because both the tremella cultivated indoors and the tremella cultivated in the wild of basswood contain more nitrates, if it is cooked for a long time, nitrate will be reduced to nitrite under the decomposition of bacteria. When people drink this soup, nitrous acid naturally enters the blood circulation, and the red blood cells in the blood contain hemoglobin, which can carry a lot of oxygen for the body's needs. However, nitrous acid has the opposite effect, which oxidizes normal hemoglobin in human body into methemoglobin and loses the ability to carry oxygen, resulting in the lack of normal hematopoietic function in human body! 5. Don't eat leafy vegetables overnight! Because some green leafy vegetables contain more nitrates, if they are left for too long after cooking, nitrates will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating. Healthy eating: Generally, the nitrate content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, and the roots and cauliflowers 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 and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables. 6. What about overnight soup? Cantonese people like to make soup, put the soup in the refrigerator and boil it the next day before drinking it. Is this overnight soup good for your health? Healthy eating: The best way to preserve the soup base is not to put seasonings such as salt. When the soup is cooked, scoop out what you want to drink that day with a clean spoon, and it is best to store it in the refrigerator with a earthen pot. Because the leftover soup is stored in aluminum pot and stainless steel pot for a long time, it is prone to chemical reaction, so it should be kept in glass or ceramic utensils.
