It's no good. It's best not to eat

Vegetables are easy to produce nitrite during storage, and the antioxidant components, vitamin C and folic acid in them are extremely lost after storage and repeated heating. The remaining meat dishes are better preserved than vegetarian dishes: on the one hand, meat dishes in the refrigerator can be preserved for 1-2 days as long as they are thoroughly heated before eating. Although some B vitamins are lost, protein can be completely preserved without producing harmful substances; On the other hand, meat dishes still taste good when heated again, while vegetables almost lose their delicious value after heating. Among the meat dishes, aquatic products should be eaten first, because the protein of aquatic products is particularly easy to be decomposed by microorganisms, and aquatic products are more likely to breed harmful microorganisms.

Some vitamins are usually lost in food after heat treatment, and the higher the heating temperature and the more times, the more vitamins are lost. Obviously, eating leftovers for a long time is easy to cause malnutrition.

The study found that it is difficult to digest leftovers after reheating, and it may cause stomach problems after a long time.
