Everyone has eaten leftover food, in fact, eating some food that has been stored overnight is not good, and it may cause some side effects that are not beneficial to our bodies. Generally, some leafy vegetables cannot be eaten after being stored overnight, such as common vegetables like cabbage, etc. Ready-to-eat dishes should be eaten on the same day.

Leafy vegetables The leaves of all leafy vegetables contain a lot of nitrates. If you leave the cooked vegetables for too long (more than 12 hours), under the action of bacterial decomposition, the nitrates in the leaves will be converted into nitrites, which have been proven to have carcinogenic effects by medical science. It is recommended not to eat green vegetables stored overnight, and there is no way to preserve this type of vegetable.

Ready-to-eat dishes should be eaten on the same day. The main reason is that there is no place to store them. Don’t think that the refrigerator is very clean, in fact, it is easy to breed mold and psychrophilic bacteria, so they should not be stored overnight. However, if they are stored properly, they are not completely inedible. You can use a保鲜膜 to seal the ready-to-eat dishes completely to prevent bacteria from entering the refrigerator. Then put them in a bag and store them in the refrigerator. They can be heated for consumption the next day, and high temperature can kill some bacteria.

Soup

There are specific methods for storing cooked soup overnight. After cooking, do not add any seasonings, and you can serve the amount that can be eaten on the same day, then add seasonings for consumption. Other soups that have not been seasoned can be stored, but attention should be paid to storing the remaining spoons and bowls that contain soup in glass or ceramic products in the refrigerator. Because soup can undergo a chemical reaction when it comes into contact with aluminum or stainless steel products, which can lead to spoilage.

Fish and seafood

All kinds of fish and seafood are prone to produce protein degradation products after being stored overnight. Eating this kind of leftover food can damage the liver and kidney function of humans. Fish and seafood that have been stored overnight should not be eaten, and there is no good way to store them.

Tremella is also not suitable for storage overnight, its harm is the same as that of vegetables mentioned above. The cooked tremella contains nitrates, which can be converted into nitrites under the action of bacteria.
