There are many kinds of leftovers on the table, including overnight dishes, overnight meat, overnight water and overnight tea. So which of these four foods can be eaten and which can't be eaten? Let's have a look.

Overnight water, overnight tea, overnight vegetables and overnight meat, which one can't be eaten?
Overnight water
After getting up in the morning, I can't open my eyes and feel sleepy. In order to get more sleep, I choose to boil water before going to bed at night. After getting up in the morning, you can drink directly from a cup. Some people think that it will produce a lot of harmful substances after boiling for one night, and drinking water for one night is harmful to the health.
According to relevant research, overnight boiling water will breed harmful substances, but it is still within the safe drinking range.
The harmful substance produced is nitrite, which is converted into sodium nitrite after entering the human body. Sodium nitrite has little effect on the body, and it is safe to drink boiled water left over overnight.
The tea left over from the day before
Tea has a history of thousands of years in China. The ancients liked to drink tea and recite poems to the moon. In modern times, tea has become a recognized health care product in the health care circle. Middle-aged and elderly people have the habit of drinking tea and water. Drinking a cup of tea after a meal can help digest food and relieve boredom.
It is not recommended that you drink overnight tea, because overnight tea will produce a lot of harmful substances, and frequent drinking of overnight tea will induce gastrointestinal diseases such as abdominal pain and diarrhea.
Overnight dish
When dining out or entertaining relatives at home, a big table of rich meals is always prepared. People in China often use Manchu-Han banquet to describe the richness of food. With the improvement of people's health care concept, more and more attention is paid to nutrition collocation. There are vegetables and meat in a big table. If people eat too many meat products, there will be almost no food left, but there will be a lot of food left every time.
The old people at home thought it was a pity to throw them away, so they put them on a plate and kept them in the refrigerator, and continued to eat after heating the next day. There are not many harmful substances in overnight dishes, but the nutritional value of overnight dishes has been greatly lost. If you continue to eat them the next day, you can only fill your stomach, but you can't provide nutrition for your body. So eating these overnight leftovers is of no practical value.
Overnight meat
We can often see some frozen meat in the supermarket, such as ribs, pork, fish and so on. These undercooked meats can be eaten continuously. Most meat can be kept in the refrigerator for a long time. As long as it can be eaten within a certain period of time, it will not bring harm to the human body.
Meat can also be eaten overnight. As long as it is properly preserved, it can be heated to continue eating.

The doctor reminded: Don't eat these dishes even if you throw them away!
Soymilk can't be drunk overnight
The shelf life of freshly squeezed soybean milk we bought in the breakfast shop is not very long. Generally, it is extruded or consumed within 4 hours. Otherwise, a large number of bacteria may breed, and the reproduction speed of bacteria is super fast. You should never drink soy milk overnight. Insisting on drinking it will definitely affect your health.
Therefore, whether it's freshly squeezed soybean milk at home or sold in an outside store, it's best to drink it all at once, not overnight.
If you can't drink it all at once, you must boil the soybean milk, cool it and put it in the refrigerator for sealed preservation to prevent deterioration. The treated soybean milk should not be stored in the refrigerator for more than 12 hours, and should not be drunk after that.
You can't drink tremella soup overnight.
Jin 'er decoction is a kind of good nutrition, but after it is left overnight, a lot of nutrients are lost and a lot of harmful substances are produced. Whether planted indoors or in the field, tremella contains more nitrate. After boiling, if left for a long time, nitrate will be reduced to nitrite under the continuous decomposition of bacteria.
After drinking this soup, nitrite enters the blood circulation, which oxidizes hemoglobin in the human body into methemoglobin and loses its oxygen-carrying ability, thus leading to the lack of normal hematopoietic function in the human body. Therefore, even if you don't want to throw it away, you can't drink tremella soup overnight.
It is better to throw away the bad goods that have not been eaten overnight.
Bad food is a kind of food that southerners like to eat, and it is the favorite of Shanghainese. As we all know, the temperature in the south is generally higher than that in the north, so even if you put the spoiled food you can't finish in the refrigerator, there is no way to inhibit the proliferation of bacteria, which is a great safety hazard.
Therefore, in order to prevent food poisoning, it is best not to eat bad goods overnight in summer, and try to eat them during the day. Even if it is put in the refrigerator, there is no guarantee that it will not breed bacteria, and it will still cause harm to the body after a long time. For the sake of health, it's best to eat these foods at once, don't put them in the refrigerator for too long, and throw them away as soon as possible.
