Actually, it is not recommended to eat leftovers, especially overnight. Because the leftovers have been left for a long time, food produces other bacteria, especially overnight meals. If it is not stored properly, it is simply a world of bacteria. So if you can, it is not recommended to eat. But if you don't want to waste food, or food with better nutrition, you need to wrap it tightly with plastic wrap and put it in the refrigerator the night before eating the next day.

In fact, leftovers cannot be generalized. Generally, it can be divided into two categories: those that cannot be eaten resolutely and those that can be eaten after heating for a certain period of time. Seafood and river fish can easily produce protein degradation products harmful to health after a night, so they can't be eaten any more. After green vegetables are processed, it is best to avoid eating every other meal.

The biggest difference between leftovers and fresh vegetables is the different nutritional value. When cooking hot vegetables, most vitamins are lost, so eating leftovers often leads to malnutrition. Leftovers usually go bad. If you eat them often, it will be bad for your stomach, which will lead to your stomach. Leftovers may produce harmful substances whether stored or heated, so there is a risk of food poisoning.

Three ways to renovate leftovers: 1, change knives. Large pieces of meat are most suitable for changing knives. Slice, dice and chop, then cook with fresh vegetables and coarse grains. 2. change the seasoning. There are two purposes of flavor change, one is to change the taste of dishes, and the other is to adjust the salinity. 3. Add ingredients. In fact, it is equivalent to introducing vegetables into a new meal instead of adding meat dishes, which is conducive to improving the nutritional balance.

For leftovers, it is recommended to leave meat and vegetables. If the substance is left for a long time, it is easy to produce toxic nitrite. When it meets protein in the stomach, it will produce carcinogenic nitrosamines. The preservation conditions of leftovers must be paid attention to. Generally, it should be sealed in time and put into the refrigerator after being completely cooled. Leftovers must be returned to the pot at high temperature before eating, because low temperature can only inhibit bacterial reproduction and cannot completely kill bacteria; Changing your diet, even if it is healthy and harmless, will inevitably make the same dish taste bad after two meals. Try to use your imagination to change your diet for them.
