Must I throw away the leftovers from the evening?

Personally, I suggest that it should be dumped, but there are also suggestions in scientific proof that some must be dumped and some can be kept.

Let's talk about the effect of overnight dishes on the stomach. The color of the vegetables marinated overnight looks no different from that of fresh vegetables, but the taste has changed. The freshness of overnight dishes is not as good as that of freshly cooked dishes. Some people who have a bad stomach can easily get gastroenteritis if they eat overnight dishes, especially when spring comes, which is the season when gastroenteritis is easy to occur. If they eat overnight food again, it will be a great torture to their stomachs.

The nitrite content in many vegetables exceeded the standard overnight. Here are some dishes that must not be eaten overnight: 1. Overnight dishes, the nitrite content of overnight dishes exceeds the standard, and nitrite is a substance that can cause cancer in the body for a long time, so it is impossible to remove nitrite by heating vegetables in time, so remind some people who love to eat overnight dishes to change this lifestyle, otherwise it will have a great impact on health;

Second, you can't eat overnight undercooked eggs, whether it's marinated eggs or white eggs, because the yolk of an egg is easy to breed bacteria when it's undercooked. Even if it can't kill bacteria by reheating the egg, it will carry nitrite in the egg. Cooked eggs can be stored for 48 hours if heated, but only if the storage temperature is not too high. For example, it is too hot in summer in the south, so it can only be stored in the refrigerator, otherwise the eggs will go bad easily. Third, you can't drink soup overnight. Overnight soup is the same as vegetables. After one night, the nitrite produced by microbial decomposition exceeded the standard, which had a great impact on health. The stomach and intestines will also react due to overnight soup, and gastric juice will not be secreted for a long time, and the gastric mucosa will be damaged. If you really want to drink this soup and are too lazy to go out, you can leave the bottom of the soup and add water to it the next day. This soup has no effect on your health. 4. seafood can't be eaten overnight. Overnight seafood will undergo chemical decomposition, and some will turn yellow. Protein in it will degrade under the action of microorganisms, and the toxin produced will cause great harm to liver and kidney;

5. It is not recommended to keep meat food with too much seasoning, such as braised pork. There is too much seasoning in the process of braised pork, and the seasoning contains nitrate in the production process. It is not recommended to eat braised pork overnight. If meat is found to be overcooked during cooking, it can be stored in the refrigerator without seasoning and can still be eaten the next day.

These are my personal suggestions. I suggest that you eat less and cook more in your life, so that you won't waste it and don't have to worry about the adverse effects of eating overnight dishes.
