First, it will lead to blindness and paralysis because of acute renal failure. Causing acute renal failure? Killer? , is it? Acute sodium retention? (that is, the content of sodium nitrite in leftovers is too high), and the content of sodium nitrite will be too high after overnight, which is raw pickles (pickled cucumbers, radishes, etc.) and seafood dishes (crabs, shellfish, etc.), and of these two kinds, seafood is the most prone to this problem, because most people know that seafood is expensive and they are reluctant to throw it away after eating it.
Second, most overnight dishes can be eaten if they are properly protected. Sodium nitrite needs to be transformed in a semi-sealed condition, but the space is ok. Therefore, it is easy to cause problems when the dishes are put directly in the refrigerator, but it is rare when they are put in the plastic wrap, because after being put in the plastic wrap, the suction generated by the evaporation of water inside the refrigerator will draw the dishes into a semi-vacuum state within a certain period of time. In this case, sodium nitrite needs to be transformed slowly.
Third, seafood and fish are not recommended overnight. However, seafood and its fish, even with plastic wrap, are not recommended overnight. Because in addition to nitrite, seafood is also prone to breed a variety of bacteria, which can also cause intestinal diseases. Generally speaking, eating a big problem is not necessarily a problem, but diarrhea is inevitable. Most people eat something that is not a big problem, but their physical fitness is poor, so it is not news to hang up for three or five days.
Generally speaking, if you don't eat overnight food, don't eat it. CD-ROM action is a perfect habit. If it doesn't work, you should keep it the night before. If you have a refrigerator, wrap it with plastic wrap and put it in the refrigerator. If you don't have a refrigerator, you can reheat it and cover it with a breathable sieve.
