Is 'overnight food' unhealthy? Suggestion: These 5 overnight foods are worth throwing away no matter how valuable they are
> > Overnight dishes have become a hot topic for some time. Some people believe that overnight dishes contain a lot of nitrite, which can easily increase the risk of cancer in the human body. Therefore, overnight dishes need to be thrown away. >
> > But some people are more frugal, and the overnight food has not deteriorated. There is no exact answer to the so-called carcinogenicity, so the overnight food can be kept and eaten with confidence. >
Overnight usually means that the storage time is relatively long, usually about 8 to 12 hours. Once there is bacterial infestation, coupled with the conditions of temperature and humidity, the nitrite in the dish will be converted into nitrite through the action of bacteria. Inflict severe damage to the human body.
If a large amount of nitrite enters the stomach with the help of gastric acid, it will react with protein breakdown products to produce amines. At this time, carcinogenic nitrosamines will be formed, which will seriously damage health.
As the old saying goes , "talking about toxicity without dose is hooliganism" . Ingestion of 300-500 mg of nitrite by the human body will cause tissue hypoxia and poisoning, but the problem is that the nitrite produced by the overnight vegetables is far below the national standard after a long time.
Of course, overnight dishes are not completely healthy. After all, if overnight food is not stored properly, it will breed a lot of bacteria, which will also lead to food poisoning and seriously affect health.
Is "overnight food" unhealthy? Suggestion: These 5 overnight foods are worth throwing away no matter how valuable they are
First, overnight seafood
Seafood is the favorite of many people. Crabs, shrimps, shellfish, and fish are all delicious, but at the same time, they can easily lead to spoilage.
The protein content of seafood is very rich. If it is not stored properly, it will cause bacterial poisoning. They contain some bacteria and perishable substances. If they are left for too long, they are more likely to breed substances that are not conducive to health.
According to relevant surveys, it is found that overnight seafood will contain protein degradation products, which will cause strong damage to the liver and kidneys, and seafood is a cold food, which will increase the probability of gastrointestinal lesions.
Second, overnight soft-hearted eggs
Half-boiled eggs are called soft-hearted eggs. Some people especially like to eat these kinds of eggs. They feel that they taste very good. After all, the eggs are not fully cooked, and there are eggs of bacteria or parasites themselves, which are easy to be infected with Salmonella.
If you are infected with these bacteria, you are prone to symptoms such as fever, high fever, headache, and even worsening ulcers, which can seriously damage your health.
Therefore, I hope that everyone should not eat this type of eggs. Even if you eat them again, you can't act recklessly, especially the soft-hearted eggs after overnight.
Third, overnight leafy greens
These three kinds of food can be said to have been interrupted. Green leaves are on the dining table, and almost everyone can eat them. If we buy too many vegetables at one time, we must eat green leafy vegetables first, not one-time. If you cook too much, you need to cook as much as you eat, because there is no way to keep the green leafy vegetables fresh overnight, and their nitrite content is also high, which is higher than that of root vegetables and fruits and vegetables. Therefore, the green leafy vegetables overnight must not be eaten again, and must be thrown away decisively.
Fourth: mushroom food can not be eaten overnight
The nutritional value of mushroom food is very high, and the delicious taste is his biggest feature. No matter what kind of bacteria it is, it is an indispensable delicacy in everyone's heart. After finishing, there will be a lot of nitrate residues on the second day. If it is stored for too long, it must be thrown away, and never eat it again.
Fifth: Overnight Luwei
Some people's favorite lo-mei food is marinated and stored for a long time. If this is the case, it is a big mistake.
Lo-flavored food is stored in the refrigerator for a long time, which is more likely to breed a large number of bacteria and viruses into the human body, which can also cause gastrointestinal lesions, and even cause abdominal pain and diarrhea, which seriously affects health.
> > How should vegetables be stored and eaten? >
Vegetables, it is best to eat and buy now, make and eat now, to reduce the storage time of vegetables, and it is best to eat them without any leftovers.
For the remaining fresh vegetables, please clean them and store them in the freezer of the refrigerator; for the remaining vegetables, they should also be sealed and stored in the refrigerator.
Vegetables are more nutritious when they are cooked and eaten now, avoiding the loss of unnecessary nutrients due to storage and repeated heating of vegetables.
> > Preserving meat should also pay attention to: >
Buy less and eat less, buy and eat now. Although there are not many nitrites in fresh meat, the preservation time of meat should be shortened.
Please choose the "refrigerator freezer" for storing meat. The low temperature can prevent the growth of bacteria; the remaining cooked meat should be strictly sealed and stored, and the meal should be fully heated.
Although the content of nitrite in fresh meat is low, cured and processed meat such as bacon and bacon contain more nitrite, which affects health.
> > For leftovers, please treat them with confidence: >
One: Leftovers need "scientific operation" and storage should be reasonable
Now that the meal is left over, please do not do any extra processing to it. Reduce the number of tableware such as chopsticks, save the leftovers for the number of times of production and growth, and use safe and clean food tableware to ensure its airtightness and separate storage to avoid bacterial cross-infection.
Two: It must be warmed up before eating
Although leftovers can be eaten, the premise must be heated thoroughly to restore the taste and taste of the food, and at the same time, it can also reduce the bacterial content of the food and help to protect the body.
Three: If you really want to "leftover", it is recommended that leftover meat not "vegetables"
From a safety point of view, it is recommended that leftover meat is not leftovers. Vegetables in each meal are recommended to be eaten at the time. Relatively speaking, meat storage contains less bacteria than vegetables.
The safety issue of leftovers is timeless. However, there is no scientific basis for the claim that leftovers cause cancer. I hope everyone will take a rational view of this issue.
