Eating leftovers is harmful to health, so how to deal with leftovers?

Eating leftovers is harmful to health. First, the harmful substances in leftovers gradually increase with the passage of time, especially harmful substances such as nitrite. Eating leftovers for a long time will increase the risk of chronic diseases such as cancer. The second is that microorganisms such as bacteria and molds in leftovers are easy to exceed the standard, which in turn leads to food poisoning and gastroenteritis.

Therefore, regarding the leftovers, we must uphold the attitude of "throw them if you can, and don't eat if you can't eat them". Never "feel wasted" and force yourself to eat leftovers, which is not worth the loss. When cooking every day, try not to leave your cooking for the next meal, when this meal is finished.

If you accidentally leave leftovers, then we should know that different cooked foods have different storage times. First, leftovers can be stored at room temperature for 5 to 6 hours; Keep fresh in the refrigerator for up to 3 days. Therefore, if the leftovers are placed at room temperature, it is best to finish the last meal and the next meal must be finished. If stored in the refrigerator, it is best to eat it within 2 days instead of heating it three times.

The storage time of fried noodles and mixed noodles is similar to that of leftovers. However, if it is noodle soup, porridge and other foods, it can only be stored at room temperature for 1 to 2 hours, so it cannot be stored until the next meal. The soup staple food must be kept in the refrigerator for 1 to 2 days, but try to finish it within 1 day, and don't heat it for three times.

If it is leftovers, it should be handled according to the type. Generally speaking, cooked meat, cooked fish and boiled eggs can be stored for 6 hours at room temperature and 3 to 4 days in the refrigerator. However, stir-fried dishes can only be stored for 4 hours at room temperature, especially leafy vegetables, which can hardly be stored until the next meal, but can be stored in the refrigerator for 1 to 3 days, and the roots can be stored longer than the stems and leaves.

Generally speaking, the leftovers should be kept in the refrigerator, and should be eaten within 1 2 days as far as possible, without repeated heating. If there is no refrigerator at home and it can only be stored at room temperature, then the leftovers in autumn and winter can be left for the next meal at most, not every other meal, let alone overnight; If it's leftover food in summer, it's recommended to discard it directly instead of keeping it.
