Grandma Wang has been feeling down lately because her breakfast has been thrown away by the child for the third time this month.

Why do you always throw away my breakfast? I make my own meal and enjoy itGrandma Wang had another argument with her daughter this morning.

Because you're eating overnight food, don't you know that after dinner, it becomes poison? It's even more powerful than arsenic, are you even going to die

Faced with her mother's argument, Grandma Wang's daughter is clearly also very impatient.

Can't it be said that after a day of eating, we can't eat anymore? We've always grown up eating like this

After listening to the child's words, Grandma Wang fell into confusion for a moment,Is overnight cooking so harmful?

Overnight vegetables like arsenic cannot be eaten?A CCTV experiment provides the answer, so those who dare not eat can understand.

How does the saying that overnight food cannot be eaten come from? Is this statement really scientific?

Many people believe that,The main reason why overnight dishes cannot be eaten is that they contain nitrite and total bacterial count.

In fact, it's not just overnight dishes,Food that has been stored for more than 8 hours can be understood as overnight dishes.

With the increase of storage time, the nitrite and the total number of fungi in the food will also continue to increase.

Experts have once stated that,A one-time intake of 0.3-0.5g nitrite will lead to poisoning, and a one-time intake of more than 3g nitrite may lead to death.

The increase in the total number of fungi can also lead to unhealthy food, with the most direct manifestation being stomach disease or cancer.

Therefore, there is a saying that overnight vegetables like arsenic cannot be eaten,So is this statement necessarily correct?

Nitrite intake does lead to poisoning,But it needs to accumulate to a certain amount before it can be reflected.

Lv Yuankai of Suzhou University once conducted an experiment to detect the nitrite content of overnight dishes.

The results showed that the nitrite content of most foods, except pickled vegetables and processed meat, would not exceed 10 mg/kg.

This data is far lower than the nitrite poisoning index,Eating an occasional meal does not cause too much trouble, mainly depending on the frequency and amount of food consumed.

In fact, nitrite itself does not cause cancer. In fact, nitrite exists more or less in the water we drink and fruit we eat.

Only the nitrite content in the above foods is very low,So there's no big problem either.

In a word, nitrite is not risky as long as it is within the scope of national food safety standards.

The concept of total fungi is easier to understand than nitrite,Bacteria multiply and thrive over time, even on overnight vegetables.

After cooking, if the food is not finished and kept on hold,So it is easy to breed bacteria, and the total number of colonies will also increase over time.

Therefore, many people may think that overnight dishes are unclean and not recommended for consumption.

A group of programs on CCTV called "Truth Investigation" once conducted such an experiment.

In this experiment, four types of vegetables were selected:Stir fried rapeseed, mushroom and fungus stir fried meat, shredded potatoes, and steamed fish.

After placing the four dishes for nearly ten hours, test the Nitrous acid content of the four dishes.

The final experimental results showed that only rape and mushrooms had a certain change in nitrite.

However, despite this, the content of these foods is far below the standard range.

That is to say,Despite being left for 15 hours, these dishes still fully meet the consumption standards.

Not only that, the group also observed the total number of bacterial colonies by storing more than 30 Chinese dishes in an environment between 4 and 25 degrees Celsius.

It was found that after 15 hours of storage,Except for some cold dishes, there was no significant change in the total bacterial count.

This indirectly proves that, except for foods that have not been heated and have a relatively high total bacterial count,The vast majority of the other heated dishes can be consumed normally overnight.

The experiment conducted by CCTV program can be said to have relaxed many people's minds, butThis does not mean that all overnight dishes can be consumed directly.

So what kind of overnight food can you eat with confidence, and what kind of overnight food should you pay attention to?

1. Vegetables

It is not recommended to eat vegetables and cold dishes overnight. If you like to eat them, you must control the quantity and frequency.

Because vegetables themselves contain a lot of nitrite,After heating again and again, the content of nitrite will increase.

Perhaps the vegetables are not a problem after being heated at night,However, reheating after prolonged storage can lead to stomach problems or exacerbate the risk of cancer.

The common dishes here are cabbage, spinach, leeks, potatoes, radishes, mushrooms, agaric, and so on.

Heating these dishes the next day is not recommended for consumption.

2. Cold Mixed Vegetables

Another type is cold mixed vegetables, which are not heated and have a relatively high total number of fungi.

After prolonged storage, the total number of fungi in cold dishes will further increase, causing sensitivity to the human stomach and not having significant benefits for digestion.

Especially for cold dishes bought outside, these food ingredients often have been stored for a long time.

After adding fresh seasoning, the first meal may not be noticeable, but the next morning,Often, there will be whitening, and at this time, cold dishes cannot be eaten at all.

3. Foods containing protein

For example, soy products and seafood are not suitable for overnight consumption.

Because most of these foods are rich in protein, although they are great supplements for the human body,But it's not like this once after the night.

Proteins that have been stored for a long time are prone to spoilage,It will decompose into sulfides, which are harmful to the human body.

Eating such food can cause discomfort in the human gastrointestinal tract, leading to stomach diseases.

4. Don't put the overnight soup in the pot

In this case, it is not recommended to continue heating as breakfast. It must be placed in a metal container.

Because the soup cooked at night will precipitate after a long time,After sedimentation, continuing to heat in the pot can easily result in a total number of fungi.

Therefore, if you still want soup for breakfast, then put the soup in a metal container and store it in the refrigerator.

Only in this way can overnight soup be healthy,However, it should be noted that the second meal should also be fully heated.

5. Properly stored

Overnight dishes can be eaten, but they must be properly preserved.

Many people don't have time to cook to avoid getting up late the next day,So I would make an extra breakfast and eat it the next day.

Whether this approach is correct or not depends mainly on the method.

If the dinner that night feels a bit heavy,So it is necessary to divide a portion in advance before eating, store it in a clean and easy way, and place it in the refrigerator.

The next morning, when eating, be sure to heat it thoroughly, so that the dishes will be healthy overnight.

If you only choose to store it at room temperature, it will lead to the proliferation of bacteria, not only affecting the taste, but also causing the problem of spoilage.

Therefore, in terms of handling overnight dishes,It is important to ensure proper preservation, as only then can overnight dishes be eaten healthily.

Many people do not pay attention to the issue of overnight meals, which can easily lead to stomach problems, and even worse, stomach cancer.

This is also the reason why many people dare not eat overnight meals, of course, this is the result of not mastering scientific methods.

Many people may suffer from stomach diseases if they do not master the correct methods,And some people are even more afraid that they may develop stomach cancer due to not mastering proper methods.

So what is the difference between stomach disease and stomach cancer? What are the early signs of gastric cancer?

First of all, stomach disease is a very common disease, with a relatively high incidence rate in adults.

General stomach diseases have obvious triggers. For example, drinking cold drinks, beer, or eating spicy food can cause pain.

Gastric diseases are generally benign lesions with relatively mild symptoms. After taking medication, there will be a significant improvement.

Gastric cancer usually has no specific triggers, and sometimes even under normal circumstances, discomfort can occur.

Gastric cancer is a malignant tumor, and its early symptoms are generally not obvious,But if the following symptoms occur under normal circumstances, it is time to go to the hospital for examination.

1. Blood in the stool or vomiting

Early gastric cancer can cause bleeding,For example, there is dark brown blood or brown blood in the vomit.

If hematemesis is accompanied by bloody stools, it is recommended to go to the hospital for examination.

2. Gastric abnormalities

If your diet or rest have been normal recently, but your stomach often experiences pain, indigestion, or nausea, you must pay attention.

Blood in the stool and vomiting may be caused by gastric and duodenal ulcers, which are common in clinical practice.

However, it should be noted that this is also one of the symptoms of gastric cancer, and such situations must not be careless.

3. Sudden weight loss

If you lose weight inexplicably but haven't exercised recently, you should pay attention at this time.

Because this may be a phenomenon where the tumor grows and the body's nutrients are taken away.

And this is also one of the early signs of gastric cancer, so if this situation occurs, it is necessary to go to the hospital for examination in a timely manner.

4. Diarrhea, constipation, or decreased appetite

If you lose interest in food, do not want to eat, or if you feel bloated after being full, you should also pay attention.

If diarrhea and constipation are also present, these are all early signs of gastric cancer.

Because if a tumor grows in the stomach, the peristalsis of the intestine can also be affected, leading to diarrhea or constipation.

summary

It seems that many elderly people are still eating overnight food, and some may have been caught.

In fact, overnight dishes are not as terrifying as people imagine,As long as the materials are selected and stored properly, they will still taste healthy.

Of course, if possible, it's best to cook and eat one meal at a time,Try to avoid overnight dishes as much as possible. In case of any discomfort caused by improper storage, it will not be worth the loss.

After reading this article, are you still as afraid of overnight food as before?Do you usually eat overnight food?
