Pay attention to the hidden arsenic of 8 summer overnight dishes

Many families have a bad habit of cooking too much food for the next day. In fact, this seemingly thrifty habit has caused potential health risks. Because there is oil and salt in the fried vegetables. After one night, the vitamins in the vegetables are oxidized, resulting in a substantial increase in the content of nitrite. After entering the stomach, it turns into nitrite. Although nitrate is not a direct carcinogen, it is a major health hazard. Therefore, usually, especially in summer, it's better not to eat overnight meals. If there are dishes that are really wasted, they must be stored in the refrigerator. But don't eat these dishes overnight.

1. Green leafy vegetables

Generally, the nitrate content of stem and leaf vegetables is the highest, especially spinach and celery, which are relatively high in nitrate content. After reheating, they are easily converted into nitrite, which is known as a very dangerous carcinogen.

2. Seafood

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

3. Eggs

Many people like to eat half cooked eggs, which we often call soft boiled eggs, but they don't know that this kind of eggs is not thoroughly sterilized, and the eggs are rich in nutrition, so it's very easy to breed bacteria, which will cause danger after eating. Therefore, it's better not to store boiled eggs for too long, and it's better to eat them immediately.

4. Tremella fuciformis

The rest of tremella, mushrooms, etc., are easy to residue a lot of nitrate. If you put it for a long time, you'd better not eat it again and throw it away as soon as possible, otherwise it may cause gastrointestinal discomfort.

5. Soup

We are often used to boiling a large pot of soup and then drinking it for several days, but if the remaining soup is stored in an aluminum or iron pot for a long time, it will form harmful substances to human body. But it doesn't mean that the leftover soup must be poured out. We can store the leftover soup in tile pot or fresh-keeping box, and then put it into the refrigerator.

6. Bittern

In summer, don't spend the night with bittern, which may cause food poisoning.

7. Soybean milk

In fact, the shelf life of fresh soybean milk is very short, generally in 2-4 hours must drink. If you want to store it, put it in the refrigerator after it is cooled to prevent deterioration. However, the fresh soybean milk refrigerated in the refrigerator should not be stored for too long. If it is more than 12 hours, it is better not to drink it again.

8. Potatoes

Potatoes can not be reheated overnight, which will not only cause the loss of nutrients, but also cause damage to our body.
