Eight overnight dishes are poisonous, it's no pity to throw them away

There will inevitably be leftovers from three meals a day, especially dinner. Many families will put the leftovers in the refrigerator and eat them the next day. In fact, many overnight dishes are poisonous. You must be aware of this at home. For the sake of your own health, try not to eat overnight dishes in the future.

1. Can overnight eggs be eaten?

Northerners: Yes, you can see tea eggs sold on the streets! Southerners: No, especially men, because it will cause hernia/scrotal swelling.

Scientist: Not necessarily! Because if the eggs are not fully cooked, and the uncooked yolk is eaten overnight, if it is not stored properly, the nutrients will easily breed bacteria, which will be harmful to health, for example: causing gastrointestinal discomfort, bloating, etc. However, if the food (eggs) is fully cooked and properly sealed and stored at low temperature (usually refrigerated temperature), it can generally be stored for 48 hours without any problems. From the scientists' tips, we can know that whether eggs can be eaten overnight does not only depend on whether they are heated, but also on whether the eggs are cooked during the first boiling. Only after the eggs are cooked for the first time, there is no problem in boiling them overnight. The same is true for tea eggs. You may not know that tea eggs are boiled twice. The first time they are boiled, and the second time the eggs are cracked, and tea leaves and other auxiliary ingredients are added, and then boiled. Therefore, tea eggs must be cooked. Nowadays, some people like to eat half-cooked eggs (the yolk is semi-liquid). Such eggs cannot be eaten overnight, even if they are cooked for the second time.

2. Can overnight Tremella be eaten?

Tremella soup is a high-end nutritional supplement, but once it is left overnight, the nutrients will decrease and harmful ingredients will be produced. Because both indoor-cultivated Tremella and wild-cultivated Tremella contain more nitrates. If they are left for a long time after being cooked, the nitrates will be reduced to nitrites under the decomposition of bacteria. When people drink this soup, nitrite will naturally enter the blood circulation. The red blood cells in the blood contain hemoglobin, which can carry a large amount of oxygen to meet the body's needs. However, nitrite has the opposite effect, oxidizing normal hemoglobin in the human body into methemoglobin, which loses the ability to carry oxygen and causes the body to lack normal hematopoietic function!

3. What to do with overnight soup?

Guangdong people like to make soup. They put the leftover soup in the refrigerator and boil it the next day before drinking it. Is this overnight soup good for the body? Healthy way to eat it: The best way to preserve it is not to add salt or other seasonings to the soup base. After the soup is cooked, use a clean spoon to scoop out the amount you want to drink that day. If you can't finish it, it is best to store it in a clay pot in the refrigerator. Because leftover soup is prone to chemical reactions if kept in aluminum or stainless steel pots for a long time, it should be placed in glass or ceramic containers.

4. Don’t eat homemade marinated food overnight

Braised food and pickled food are both seasonal dishes that Shanghai citizens like to eat. Many citizens also like to put the leftover braised food and pickled food in the refrigerator "overnight", but this practice poses a great food safety risk. To prevent food poisoning, do not leave braised food overnight in spring and summer.

Bulk braised food should be consumed on the same day and cannot be left overnight. From a food safety perspective, this is unhygienic and it is best not to eat overnight leftovers if possible. Food experts remind that even food stored in the refrigerator is not absolutely "safe". Mold and psychrophilic bacteria are easily bred in the refrigerator.
