Eat leftovers often, okay? Why?

1, overnight green leafy vegetables

Because some green leafy vegetables contain more nitrate, if they are left for too long after cooking, nitrate will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating.

2. Overnight seafood damages liver and kidney.

Seafood such as crab, fish and shrimp will produce protein degradation products overnight, which will damage the function of liver and kidney. If you really buy too much, you can put raw seafood in a fresh-keeping bag or box, freeze it in the refrigerator and cook it next time.

Extended data:

1, sealed and kept.

Sealing can reduce the chance of contact between vegetables and microorganisms. Seal the food with plastic wrap, then put it in a fresh-keeping box and put it in the refrigerator for refrigeration.

2. Reduce storage time

Because the process of reducing nitrate to nitrite by nitrate reductase in microorganisms is essentially a biochemical reaction, the longer it is preserved, the more nitrite will be produced. So don't leave the dishes overnight for too long, and solve them as soon as possible.

Step 3 blanch the vegetables in advance

First, blanch raw vegetables with boiling water, and the contents of nitrate and nitrite are greatly reduced, so the nitrate content in cooked vegetables is naturally reduced, so there is no need to worry about storing them in the refrigerator. In a word, it is best to quantify the food according to the need, and try not to leave the food for the next day, which is not only beneficial to health, but also can avoid waste.
