As a traditional virtue of the Chinese nation, especially the older generation, thrift and thrift have become a part of life, and they will be very distressed if they discard the leftovers of the night before.
The previous night's uneaten meals will be stored in the refrigerator, the second day to take out the hot and then eat convenient, and can eat vegetables, I believe most people eat excess food leftovers experience, but there are also some young people feel that leftovers leftovers storage time is too long, will breed bacteria and viruses, not recommended to eat.
The older generation of people have lived in this way, in the previous years we did not have a refrigerator, lettuce leftovers can also be stored, so now the refrigerator is more convenient, why can't you eat overnight meals?
01
What is an overnight dish?
I believe that most people will automatically classify the meal made the night before as an overnight meal, in fact, from the moment the meal is prepared, more than 5 hours away is even an overnight meal.
If the dish is cooked at 8 o'clock in the morning, then the meal after 1 o'clock in the afternoon, even if it is an overnight meal, in fact, we do not need to worry too much, whether the overnight meal can be eaten, but also need to be analyzed on a case-by-case basis.
02
Is it true that overnight meals cannot be eaten?
In the actual point of view to analyze food, after cooking, regardless of whether there is overnight will produce nitrite, when the intake of nitrite reaches 0.3 ~ 0.5 grams, it will cause body food poisoning, more than three grams, may cause life-threatening.
However, the nitrite content of overnight meals alone is some distance from the dose of human poisoning, and eating an overnight meal occasionally does not increase the risk of cancer and does not cause food poisoning.
It is worth reminding that if you consume a large amount of overnight meals for a long time, the nitrite content in the body will continue to increase, and the influence of other factors will increase the risk of cancer in the body, and even for the stomach and intestines.
This does not mean that the nitrite content in all overnight meals is relatively high, and the common melon vegetables rhizome vegetables contain relatively low nitrites, which are stored properly and will not cause substantial damage to the body.
03
Reminder: Except for these 4 kinds, the others cannot be eaten
1. Seafood
Whether it is people in coastal areas or inland areas, they like to eat seafood, seafood is complete, and rich in nutritional value, delicious taste, loved by many people.
Here to remind everyone that no matter how delicious seafood overnight, it is best not to eat seafood, after thermal storage will produce more protein degradation of the object ingested too much substance, will cause damage to liver cells and kidney cells.
If the body is not able to decompose toxins normally, metabolites and toxins in the body gradually affect the individual's physical health state, so overnight seafood is best thrown into the trash can, do not eat again.
2. Stem and leaf vegetables
Like cabbage, oil wheat vegetables, cabbage, spinach this category belongs to the typical stem and leaf vegetables, stem and leaf vegetables although rich in taste, rich in vitamins for the body to supplement trace elements, help to maintain the activity of life.
However, after the overnight stem and leaf vegetables try not to eat, breeding nitrite content is high income income is easy to lay a safety hazard for health.
3. Mushroom vegetables
Enoki mushrooms, apricot abalone mushrooms, mushrooms, fungus This is all mushroom food, mushroom food after overnight, if it is eaten by the human body, it is easy to have diarrhea or gastrointestinal pain, indigestion and other diseases.
For the sake of health, it is best not to eat mushroom food overnight, especially foamy mushrooms, food such as dried fungus, dried mushrooms, it is best to eat first.
4. Marinated meat
Brine duck, chicken claw, pig's head meat, these are common brine meat in life, rich in taste and loved by many people, but also a common appetizer on our table.
This kind of meat will add more condiments in this process, and the overnight brine products should not be eaten again, even if they are put in the refrigerator for refrigeration, it is easy to breed bacteria and other viruses.
When you take it out on the second day and eat it again, it will increase the burden on the stomach and intestines and affect the overall health state, so it is recommended that you buy less or do not eat on the second day.

Tips: These two foods may be more harmful than overnight meals
1. Moldy food
Food spoilage, in daily life is very common, whether it is grain fruits or vegetables may appear moldy and deteriorated phenomenon, storage time is too long or the environment is too humid, there may be a certain amount of mold.
These molds, when present, breed large amounts of aflatoxin and other active bacteria, which, as a typical highly toxic substance, are more than 68 times more toxic than arsenic.
On the other hand, the intake of too much moldy food will damage the activity of liver cells, harmful substances or other foods must be broken down by the liver, so it is best not to eat moldy food.
2. Grilled meat
When the fire is large or the roasting time is too long, it is easy to appear the phenomenon of roasting paste, and there will be harmful substances and carcinogens in this kind of food - benzopyrene.
If the long-term intake of meat that has been roasted paste is then the risk of cancer will continue to increase, on the other hand, smoked fish, fried food, bacon also has a class of carcinogens, in order to be healthy, try to eat less.

Read further: How should overnight meals be stored?
1. Low temperature storage
If the overnight meal is stored at room temperature of more than ten degrees Celsius, the bacteria will multiply rapidly, resulting in the occurrence of spoilage in a short period of time, resulting in other pathogenic bacteria and toxins, and greatly increasing the content of nitrite.
If placed in the refrigerator below 4 degrees, it can inhibit the reproduction and growth of microorganisms, inhibit the activity of nitrate reductase to reduce the production of nitrite in vegetables, the storage time and storage conditions of vegetables will affect the production content of nitrite, and the road refrigeration placed in the refrigerator can greatly reduce the amount of nitrite.
2, do not flip casually
Unfinished meals should be peeled out in advance and put into the refrigerator for preservation, do not turn over for a long time and then save, the longer the vegetables are turned, the greater the risk of infection with microorganisms, so as to better control the production of nitrite and ensure the safety of vegetables.
According to the experimental extraction, spinach is not turned into beans after cooking, put into the refrigerator below 4 ° C, spinach and other green leafy vegetables, and the nitrite content can increase from three mg to seven mg within 24 hours.
The human body eating 0.2 grams of nitrite may produce a toxic reaction, which is a minimum bottom line, we do not need to worry too much, it is recommended that the meals put in the refrigerator do not flip casually.
3. Minimize the storage time
This is mainly because nitrite is reduced to nitrite by the microorganism in the process of reducing nitrite to nitrite, which is a biochemical reaction that lasts longer, then the more nitrite content the vegetable produces, it is recommended that you reduce the storage time of overnight meals.
