What are the dangers of eating food overnight?

Eating food overnight is likely to cause abdominal pain, bloating, vomiting, diarrhea and other symptoms, and in severe cases, edema and various inflammations of the gastrointestinal mucosa, and even food poisoning.

I think that the overnight food may have deteriorated, and many of the microorganisms in it may no longer be suitable for us, and may harm our body organs, and it will also harm the body, so it is best not to eat overnight food.

It can affect your physical health. If it is severe, it can even cause food poisoning, which will make your body particularly painful, so you can't eat overnight food.

Overnight food can easily cause bacteria to multiply, and after eating, it will destroy the intestinal flora, cause gastrointestinal inflammation, and even cause cancer.

In order not to waste leftover food, many people save the leftover food they ate at night for tomorrow. However, not all foods can be eaten overnight, some may cause you diarrhea and stomach pain after eating, and fish and seafood are prone to protein degradation after overnight, which will damage liver and kidney function.

Eating overnight food can lower a person's immunity and can also cause us to have diarrhea or vomit. If the food left overnight is not properly placed, it is easy to be infected by bacteria, and the nutritional value of the food will also decrease, and nitrite will be produced that is harmful to the human body. I think if you still eat as much as you can, you can cook as many meals as you can, and don't leave them overnight.

If the overnight vegetable colony placed at room temperature exceeds the standard, it is not recommended to eat, if you want to eat, it is recommended to put it in the refrigerator, especially the leaf vegetables have the highest nitrous acid content. For office workers who need to bring food the next day, it is best to keep it in the refrigerator.

Some of the overnight food can not be eaten, some can be eaten, green vegetables and seafood should not be eaten overnight, the light ones have stomach pain, and the heavy ones go directly to the hospital.

Food does not necessarily become toxic immediately overnight, but some foods may undergo quality changes after being stored overnight, leading to the production of harmful substances or the growth of infiltrating bacteria, which may increase the unsafety of the food. While scientific research has not yet definitively proven which overnight foods can cause serious harm to the body, here are some overnight foods that may need attention, as well as possible food safety issues:

Overnight rice: Overnight rice is prone to bacterial growth, as starch can be a medium for bacterial growth. Improper storage or reheating can lead to food poisoning, triggering problems such as diarrhea.

Overnight Fish Age: Fish are susceptible to spoilage because the proteins in them are easily degraded by bacteria. Fish that are left overnight may produce amines, which in some cases may be linked to headaches, high blood pressure, and other problems.

Overnight meat: Meat is just as susceptible to bacterial contamination, where proteins and fats can break down under inappropriate conditions to produce harmful substances. Nitrates, which may be produced in meat, may also be linked to carcinogenesis.

Frying food overnight: Foods fried overnight may become hard, taste poor, and may produce undesirable oxidation products at high temperatures.

Overnight dairy: Unprocessed overnight dairy products can ferment and spoil, increasing the number of harmful bacteria.

Overnight vegetables: Some vegetables may lose their nutritional value after being left overnight, especially those rich in vitamin C.

Overnight seafood: Seafood is prone to spoilage, so overnight seafood can be a food safety risk.

Still, not everyone will immediately develop serious health problems as a result of consuming overnight food. The way food is handled, stored, and reheated can all affect its food safety. To ensure food safety, here are some things you can do:

Food should not be left overnight, try to store leftover food in time after meals.

Food should be stored at room temperature for too long and it is best to put it in the refrigerator as soon as possible.

Use airtight food containers to preserve leftover food and prevent bacterial contamination.

When reheating overnight food, make sure it is sufficiently heated to the right temperature to kill bacteria.

In conclusion, although science has not yet clearly proven which overnight foods can cause serious harm to the body, it is advisable to follow proper food storage and handling principles to ensure food safety and health. If in doubt, you can consult a food expert or doctor for advice.

Here are six foods that should never be eaten overnight:

1. Vegetables. Vegetables that are left overnight should never be eaten, because after the vegetables are left overnight, the color will become very ugly, which will not only affect the appearance, but also produce a lot of nitrite in the vegetables.

2. Seafood. Seafood is very rich in protein, so if the seafood is left overnight, it will cause the protein in it to decompose and denature, and produce some residues of protein decomposition, which are very bad for people's health. In addition, spoiled seafood will be relatively toxic, which will cause diarrhea, food poisoning and other problems.

3. Soy milk. Soy milk is a breakfast choice for many people, and some people will choose to beat the soy milk in the evening in order to save time, and drink it directly in the morning on the second day. However, this practice will actually greatly reduce the nutritional value of soy milk, and the soy milk will produce some toxicity after being left for more than 12 hours.

4. Cold salad. In summer, everyone will eat refreshing and delicious cold vegetables, which should not be left overnight, because compared to fried dishes, cold vegetables have not undergone a high-temperature sterilization and sterilization process, so the rate of bacterial growth will be faster. Basically, the bacteria in the salad that have been left overnight are beyond the range that the human body can tolerate.

5. Half-raw eggs. Some people like to eat half-raw eggs, although such eggs are more delicate in taste, but also bring people a relatively large hidden danger. Half-raw eggs themselves will have a lot of bacteria left, and after one night of storage, bacteria will grow faster, so try not to eat half-raw eggs overnight.

6. Tremella fungus. Tremella fungus is a relatively common mushroom food, and it is often thought that white fungus and fungus need to be soaked before eating, so there is no problem with leaving it overnight. In fact, during the soaking process, these ingredients provide a good space for bacteria to grow, and leaving them for too long will cause problems with the safety of the ingredients.

Some foods are prone to bacteria and toxins and should not be consumed overnight. Here are some foods that should not be consumed overnight:

Hard-boiled meat and hard-boiled eggs: Hard-boiled meat and hard-boiled eggs should be eaten immediately or refrigerated, as they are prone to bacterial growth. If left out for too long, bacteria can multiply and produce toxic substances that can lead to food poisoning.

Cooked seafood: Cooked seafood should be eaten within a day or kept refrigerated. If left for too long, the Hososhu Taka fungus in seafood can multiply and produce toxic substances.

Cooked rice: Bacteria may be present in cooked rice that is cooked by hand and can easily grow at room temperature, so it should be refrigerated or eaten immediately and should not be stored overnight.

Cooked tofu and soy milk: Cooked tofu and soy milk should be consumed within a day or kept refrigerated. If stored for too long, tofu and soy milk can spoil and produce bacterial toxins.

Sashimi: There may be parasites present in sashimi, so they should not be stored overnight as the parasite eggs may become adults during the preservation process, affecting health.

1. Boiling water can not be drunk overnight, tap water is boiled for 3 5 minutes, the content of harmful substances such as nitrite and chloride is the lowest, and it is most suitable for people to drink. Drink less overnight boiled water: nitrite can form carcinogenic nitrosamines in the human body.

After 24 hours of boiling water, the nitrite content is twice that of the first boil.

2. Eggs can not be eaten overnight, if the eggs are not fully cooked, the uncooked egg yolk is eaten overnight, and in the case of improper storage, nutritious things are easy to breed bacteria and harm health. However, if the eggs are cooked thoroughly and properly sealed at low temperatures (the temperature at which they are usually refrigerated), they can generally be stored for up to 48 hours. Only after the first boiled egg is cooked, it is no problem to cook it again overnight.

This is also the case with tea eggs.

3. Overnight tea can not be drunk, overnight tea due to too long, most of the vitamins have been lost, and the protein and sugar in the tea soup will become nutrients for bacteria and mold reproduction, so people usually think that overnight tea can not be drunk.

4. Tremella can not be eaten overnight, because whether it is indoor cultivation of Tremella fungus and basswood field cultivation of Tremella fungus contain more nitrates, after cooking, if the time is longer, under the decomposition of bacteria, nitrate will be reduced to nitrite.

5. Don't eat leafy vegetables overnight, usually stem and leaf vegetables have the highest nitrate content, melon vegetables are slightly lower, and roots and cauliflower 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.

6. Don't eat lo-mei overnight to prevent food poisoning, and don't eat lo-mei dregs overnight in spring and summer. Food experts warn that even food kept in the refrigerator is not absolutely "insured". Molds and psychrophiles are easy to grow in refrigerators.

1 It is said that these two kinds of water will produce a large amount of nitrite after the night of the celery feast, which is harmful to health. In fact, experimental data has shown that when water is boiled for more than 30 minutes, the nitrite level will remain stable and will not change significantly overnight.

As for overnight tea, although its first color will become darker after a long time, the nitrite content after overnight is indeed about 2 times higher than when it was first brewed. But don't worry, the nitrite standard for drinking water in China is 1 mg L, and the tea that has been overnight still does not exceed the standard, which is safe.

However, the tea will not taste good if it is left out for a long time, so try not to leave it overnight.

2. Whether you can eat the leftovers overnight mainly depends on whether the method you save is suitable or not.

Suggestion: Try not to have leftover vegetarian dishes and cold dishes. Vegetables themselves have more nitrates, and nitrite is more likely to be produced than meat; Cold dishes, on the other hand, are more susceptible to bacterial contamination. Refrigerate in time, if you can go into the refrigerator as soon as you get out of the pot, if you eat the last leftovers, then as soon as possible, don't wait until room temperature and then refrigerate;

Be sure to heat it thoroughly before eating, whether it is meat or vegetarian dishes, the best way to sterilize is to heat it thoroughly.

3 Watermelon is a nutritious meal for bacteria, and hundreds of thousands of offspring can be multiplied in a few hours, let alone overnight.

For watermelons that can't be eaten, overnight is actually not terrible, but two things need to be done: wrap it in plastic wrap and put it in the refrigerator in time. The plastic wrap can isolate the watermelon from other foods in the refrigerator and avoid secondary contamination; Refrigeration can reduce the activity of bacteria, allowing them to grow more slowly.

Of course, from the perspective of freshness, the most recommended thing is: buy smaller melons, wash and refrigerate, and eat them freshly.

4 There is no risk of overnight eggs, the key is that they are not cooked thoroughly, eggs are a kind of food that is easily contaminated by bacteria.

In fact, if the eggs are boiled thoroughly and refrigerated in time, there is no need to worry about overnight, and they can be eaten even for 3 or 4 days. But usually, in order to pursue the taste, many people like to eat soft-boiled eggs that are not cooked thoroughly. Such eggs are not sterilized thoroughly enough, and there is a risk of bacterial contamination.

If you are unlucky, it can lead to foodborne illness.

Everyone's worries about overnight food are actually two words - bacteria.

Food is rich in nutrients, overnight usually means a longer time (8 12 hours), if there is bacterial contamination, as long as the temperature and humidity are right, they will grow and multiply rapidly, causing food to spoil and produce toxic and harmful substances.

Therefore, the 2 key points to ensure the health of overnight are: reduce bacterial contamination and control the temperature.

The weather is getting hotter and hotter, and the overnight food is not well preserved, and the deterioration will be harmful to the human body, so it is recommended to eat the same day of the meal and not eat the overnight food. After watermelon is left overnight, it will make our gastrointestinal tract feel uncomfortable, green leafy vegetables will produce carcinogens overnight, and food such as cakes cannot be eaten, which will also cause us diarrhea.

Watermelon can't be eaten and put in the refrigerator, it will spoil on the second day, the weather is getting hotter and hotter, many people want to buy watermelon, a watermelon is very big, you can't eat it all at once, so put it in the refrigerator on the second day is once and for all? This idea is wrong, many people are reluctant to throw it away in order to save money, and then eat watermelon on the second day, which will cause us gastrointestinal colds and gastrointestinal discomfort, and serious ones will cause us diarrhea. There is a neighbor who has been in the refrigerator for three days because he ate watermelon overnight, which led to his hospitalization for half a month.

Watermelon overnight is harmful to a lot, don't ignore your health in order to save money.

Overnight meals will produce carcinogens, which are harmful to the human body, and many green leafy vegetables are not eaten and not properly stored after being put in the refrigerator, resulting in mutual infection between the bacteria in the refrigerator and its bacteria, and eating them again on the second day will cause us diarrhea. In the summer, green leafy vegetables spoil very quickly, even meat, it will spoil on the second day, light sour and stinky, do not save a little money, bury serious hidden dangers to our health. In recent years, people have a very high chance of developing cancer, and some studies have shown that it is related to our long-term life behavior, from childhood to adulthood, we are eating leftovers, and it is impossible to throw away all the food at home on the second day, and the rice also has a shelf life, and after the second day, the protease in the rice will be decomposed, and bacteria will be produced, so the best way is to eat as much as you can.

My mother's lifestyle is very desirable, she said, doing less may be thought to be very picky, but the purpose of this is good for our health, not to eat leftovers, not to let leftovers produce carcinogens, affect our health. Cook as much as you can, and don't overdo meals to your own health, planting a time bomb.
