Parents abandon leftovers and leftovers, but they can cause cancer because of toxic?

Although the weather is getting colder, the summer heat has not yet faded, and the "overnight" seems to have magic.

Adding them in front of any food seems to have a subtle sense of indispensable.

Eat, or not? This question.

Do not drink overnight water?

Earlier, some health institutions have said that there will be a certain amount of nitrite in overnight water, but in recent years, it is found that even if the overnight water produces nitrite, the content is minimal, which is not enough to cause damage to the human body.

Based on the actual situation, many families will always have some boiling water and put them into the pots, leaving for the second day to drink.

But in fact, the experimental data shows that after 30 minutes after the water is boiled, the content of nitrite will be relatively stable. Even if it will not change one night, it will be far from safety standards.

It is only recommended that overnight water during overnight storage, you may wish to bring a lid to prevent the dust from falling into the water.

Do not drink overnight tea?

Compared with overnight water, the color will become darker after the overnight tea is put. At the same time, the nitrite content after overnight increases by about two times higher than when it is soaked, reaching 0.251mg/L.

But don't worry too much, the nitrite standard for drinking water in my country is 1mg/L. Therefore, even after one night after one night, the tea is still not exceeding the standard, which is in line with the scope of safety.

However, there is a problem that-compared with overnight water, overnight tea risk is high.

It is not carcinogenic, mainly because tea water will breed certain bacteria after placing, and the amount of bacteria without drinking bacteria for a long time will increase, which will cause the human body to infect digestive tract and gastrointestinal diseases.

In terms of taste, the texture of the tea mouth on the second day has a significant decline in the taste of the tea, and it has a astringent taste. Tea drinkers try to finish the tea on the same day, and pour the remaining residue. Rinse the bottom.

Do not eat overnight dishes?

Although there are some flavors such as edible oil and salt in the dishes after being cooked. After a period of time, the vitamins in the dish have been oxidized, which will increase the content of nitrite significantly.

However, nitrite itself does not have carcinogenic properties or toxic substances. If it is taken by the human body, it will be converted into a ingredient called nitride, and this ingredient is precisely a carcinogen.

However, we cannot "put aside the dosage and toxicity", even after one night, the nitrite content of Chinese nitrite in China is within the scope of safety.

At the same time, not all overnight dishes contain a large amount of nitrite ingredients. The nitrite ingredients in all cooked green leafy vegetables are high, and the nitrite components contained in some melon vegetables are relatively low.

It is also due to time and food for overnight dishes. For example, some fresh green vegetables, if they are placed in a refrigerator or a lower temperature environment, can be eaten as appropriate after heating on the second day, but the taste has decreased.

Whether the leftovers can be eaten overnight depends on the way you save.

After all, in this summer, if leftovers leftovers were placed outside the room temperature for one night ....... The taste of the next day is sour!

All overnight concerns are mainly to delve into two words-bacteria!

Because food itself is rich in nutrition, overnight means that the placement time is longer, usually 8-12 hours.

Once the food suffers from bacterial pollution, as long as there is a suitable temperature and humidity, it will grow quickly to reproduction, which will eventually lead to corruption and deterioration of food and toxic and harmful substances.

Therefore, in order to ensure whether the food is healthy, you need to do these 2 points -----

Reduce bacterial pollution and control temperature.

Therefore, as much as possible leftover vegetables, especially vegetables and cold dishes. If you can't finish it, you need to refrigerate in time in time. Don't wait until the room temperature is refrigerated.

At the same time, whether it is amaranth or vegetarian dishes, the best way to sterilize is to completely heated.
