What are the dangers of overnight vegetables

Refrigerators have become a must-have household appliance for every household, and they also play a very important role in daily life. For example, they play an irreplaceable role in keeping food fresh. In line with the traditional virtue of diligence and thrift, many families will put the food that they cannot finish on the first day into the refrigerator to keep it fresh and continue eating it on the second day. However, some overnight vegetables can cause great harm to the human body, so what kind of harm can overnight vegetables cause?

Why are overnight dishes harmful?

1. A large number of bacteria multiply. People are accustomed to putting overnight dishes in the refrigerator. If they are kept in a moist state for a long time, a large number of bacteria will breed. When they are heated again the next day, the bacteria cannot be completely killed. If this continues for a long time, it will cause gastrointestinal diseases and even food poisoning.

2. Produce nitrite. The nutritional value of overnight green leafy vegetables has been destroyed, and nitrite will also be produced. Once the nitrite enters the stomach, it will form a strong carcinogen and induce gastric cancer.

What overnight dishes should we pay attention to?

1. Overnight seafood

Overnight seafood will produce protein degradation products, which can seriously damage the kidneys and liver. Long-term consumption will reduce liver and kidney function, so you must not eat overnight shrimp, crabs, and shellfish.

2. Undercooked eggs

The yolk of an uncooked egg is in a semi-solid state. Because this type of egg is not cooked, it will produce a large number of pathogenic bacteria. If it is left overnight, it is more likely to cause bacterial infection.

3. Green leafy vegetables

Green leafy vegetables cannot be eaten if they have been stored for a long time because they contain a lot of nitrates, especially celery and spinach. After repeated heating, it will be converted into carcinogens that are harmful to the body. Some people like to put the meals prepared the night before directly in the refrigerator and take them to work the next day. They try to choose root vegetables and cauliflower.

4. Fungus and mushrooms

Mushroom foods such as shiitake mushrooms, white fungus and black fungus contain a large amount of nitrate. If they are cooked and left for too long, they will be converted into nitrite.

5. Stew

People in the south like to make soup, and sometimes they make too much soup at night and are reluctant to throw it away. Try not to keep stewed soup in an aluminum or iron pot for a long time, otherwise it will decompose some substances harmful to the human body. You can put it directly in a clean ceramic bowl, seal it with plastic wrap and put it in the refrigerator after it cools down.

Kind tips

For the health of your family, try not to eat overnight food, especially overnight mushrooms and seafood. Otherwise, a large amount of nitrites will be produced in the body, causing serious harm to the body and even leading to food poisoning. Eat more fresh vegetables and fruits. Also, do not leave food out for too long, otherwise its nutritional value will be reduced.
