Overnight soup can also be said to be drinkable, but only if it is preserved and cooked properly. Otherwise, it will be harmful to our health. The best way to preserve soup is not to put seasonings, such as salt and monosodium glutamate, so it should be put away before cooking, and filled with glass or ceramics, because if it is kept in stainless steel pot for a long time, it is easy to have chemical reactions.

Some foods stored overnight are not good and may even be poisonous. For example: eggs. Many people like to eat uncooked egg yolk when cooking soup, but if the uncooked egg yolk is not preserved overnight, it will easily breed bacteria harmful to our human body, which will not only lose nutrition, but also deteriorate, which may lead to gastrointestinal discomfort and so on.
