Is it OK to eat leftovers, overnight dishes? What are the effects on health, harm

After being left for a long time, leftovers are easy to produce harmful substances such as potassium sulfite and sodium sulfide that are harmful to the human body, which will damage the human digestive system, resulting in stomach acid, stomach swelling, dizziness, and in severe cases, it may also lead to nausea and diarrhea and other poisoning phenomena, so it is recommended that you eat less leftovers and leftovers! If you can't eat it, you must fully heat the leftovers and leftovers before using them to minimize the survival of harmful substances!

From a medical point of view, it is not good to put leftovers in the refrigerator after cooling, because hot food suddenly enters a low temperature environment, the food center is prone to qualitative changes, and the heat brought in by the food will cause the condensation of water vapor, promote the growth of mold, and lead to the mildew of the food in the entire refrigerator. The food stored in the refrigerator must be returned to the pot after being removed, because the temperature of the refrigerator can only inhibit the growth of bacteria, not kill them completely. The storage time of leftovers should be eaten at noon, and the leftovers at noon should be eaten at noon, and the leftovers at noon should be eaten at night, and it is best to eat it within 5-6 hours.

Because under normal circumstances, some bacteria, viruses and parasites can be killed within a few minutes by heating at a high temperature of 100 degrees Celsius. However, if the food is stored for too long, the bacteria in the food release chemical toxins that can be heated and powerless. It is important to take care of leftovers.

Of course, it is best to have no leftover rice and put it in the pot according to the amount of rice per person. If leftovers, they should be loosened and placed in a ventilated, cool and clean place to avoid contamination. Vegetarian dishes should not be packed, because in the process of making vegetarian dishes, less salt is generally used, and the cooked vegetarian dishes will be put for a long time at a relatively high temperature, and the bacteria in the dish will multiply in large numbers, and nitrate will be reduced to nitrite under the action of bacteria.

Bad overnight toxicity is harmful to health.

It's not good, because after a long time, the nutrients of things will also decrease, and bacteria will also grow, if there are leftovers, be sure to warm them thoroughly and put them in a cool place!

I think it's very harmful to your health, because the overnight meals are actually moldy and bacterial.

Eating overnight meals is harmful to your health, because the leftovers of the overnight will increase the number of bacteria after being stored at night, which is not good for your health.

Overnight meals are prone to nitrite, a chemical that can cause cancer when consumed for a long time, and overnight meals contaminated by bacteria will multiply in large quantities and easily cause digestive diseases and endanger health. If the overnight dish does not deteriorate, it is okay for adults to eat it once in a while, and the child is in the development stage, so it is not recommended to eat overnight meals.

It is harmful, because there are more bacteria in these things, and it may harm our internal organs after eating.

In general, stem and leaf vegetables have the highest nitrate content, melon vegetables are slightly lower, and root and cauliflower are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables such as bok choy, spinach, etc. first. If you're going to cook more and eat it hot the next day, try to avoid leafy vegetables in favor of melons.

It is best to eat green vegetables within 4 hours after processing, especially in summer, and if you can't finish the green leafy vegetables, don't leave them overnight. Spinach and celery, in particular, are relatively high in nitrates.

When reheated, it is easily converted to nitrite. Overnight meals may rot, causing a series of bacterial fermentation, followed by mold and other harmful bacteria or fungi. Therefore, it is easy to have some abdominal symptoms after consumption, such as abdominal pain, bloating, nausea and vomiting, acid reflux, heartburn, diarrhea, fever and other manifestations.

At the same time, long-term overnight meals will also cause damage to the mucosa of the gastrointestinal tract, which is easy to cause congestion, edema, inflammation, etc., and then prone to erosion, ulcers, bleeding and other lesions. The harm of overnight vegetables is carcinogenic.

Some green vegetables contain nitrate, I believe some friends who have studied chemistry know that nitrate is a general term for nitric acid-derived chemicals, if the vegetables are cooked for too long, the nitrate will be reduced to nitrite under the decomposition of bacteria in these vegetables, nitrite has a carcinogenic effect. The harm of nitrite, a carcinogen contained in overnight dishes, is relatively small, and the harm of overnight dishes mainly comes from microbial contamination. If the dosage is large, there will be poisoning, and long-term ingestion will cause carcinogenicity.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Eating overnight vegetables is particularly easy to cause cancer, because the food has undergone qualitative changes overnight, and the loss of nutrients is more, which is particularly easy to lead to gastroenteritis, diarrhea or stomach distention, and regular eating of overnight vegetables will also lead to increased blood pressure and blood lipids.

Eating overnight vegetables may lead to the intake of germs, which may spoil the food overnight, have a risk of causing cancer, damage internal organs, affect the development of the body, and produce more nitrates to harm the body.

It can put us at risk of cancer. Food poisoning. We can't digest it and have allergies. Suffering from intestinal diseases,

It can breed bacteria, which can lead to kidney failure, sometimes food poisoning, sudden death, and also lead to three highs.
