Benefits and disadvantages of leftovers What are the dangers of eating leftovers

According to scientific determination, some overnight vegetables, especially overnight green leafy vegetables, not only have low nutritional value, but also produce disease-causing nitrite. The amount of nitrite in stored vegetables increased with the extension of storage time and the increase of temperature, while the increase of nitrite was less if the vegetables were refrigerated in the refrigerator (2-6 degrees Celsius).

The amount of nitrite produced in different types of vegetables under the same storage conditions was inconsistent. In general, stem and leaf vegetables are the highest, melon vegetables are slightly lower, and root and cauliflower vegetables are in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat stems and leaves first, such as Chinese cabbage, spinach, etc.

If you are going to cook more vegetables and eat them hot the next day, you should try to make less stem and leaf vegetables and choose melon vegetables.

There is oil and salt in the fried dish, and after one night, the vitamins in the dish are oxidized, which greatly increases the nitrite content, and becomes nitrite after entering the stomach, although nitrate is not a direct carcinogen, but it is a major hidden danger to health. After nitrite enters the stomach, it produces a substance called NC (N-nitroso compound) when certain conditions are met, which is one of the risk factors for gastric cancer. Especially when the weather is hot, overnight meals are contaminated with bacteria and can multiply in large numbers, which can easily cause gastroenteritis and food poisoning.

Among the fried dishes, many of them can't be eaten and stored, especially some high-protein and high-fat leftovers, which can't be eaten. Harmful bacteria in the air will attach to leftovers and start to multiply within 2 hours, and we all know that most of the proteins and fats will produce harmful substances under the action of bacteria, such as hydrogen sulfide, amines, phenols, etc., which are harmful to the human body. It is an indisputable fact that eating leftovers for a long time is easy to cause cancer.

Therefore, you can't eat overnight dishes, and when cooking, the best thing to do is to tailor it to your health, and not to the detriment of your health!

The good thing is that you don't waste money and save money! The disadvantage is that it may produce harmful substances, and eating too much is not good for the body.

In winter, when the temperature is low, you can eat some, but in summer, don't eat leftovers from overnight, because the temperature is high and it is easy to spoil.

The advantage is that there is no waste of food, and the disadvantage is that sometimes it will hurt your stomach! (^

Benefits: Save food.

Disadvantage: Harmful to one's own body.

The hazards of long-term leftovers include malnutrition, food poisoning, and increased risk of gastrointestinal diseases.

After repeated heating or brewing with boiling water, water-soluble vitamins such as B vitamins almost disappear, and most minerals are also lost, and long-term consumption is prone to malnutrition. The nitrite content in leftover rice will gradually increase with the increase of storage time, and it is easy to cause nitrite poisoning after long-term consumption, and poisoning symptoms such as abdominal pain, diarrhea, dizziness, and headache will appear.

Improper storage of leftovers is extremely easy to breed bacteria, and long-term consumption will cause a large number of bacteria to enter the gastrointestinal tract, increasing the risk of gastrointestinal diseases. It is not recommended to eat leftovers for a long time, and you should cook on demand. Also, when eating leftovers, be sure to heat them well.

Leftovers can bring the following four health hazards:

1. Cause food poisoning. Leftovers are stored in the refrigerator and can be contaminated with germs, and if they are taken out of the refrigerator and eaten without adequate heating, they can get food poisoning.

2. Cause malnutrition. There are few water-soluble vitamins such as vitamin C and B vitamins left in leftovers, and the nutrients are almost gone.

3. Increase the possibility of cancer. Leftovers contain a lot of nitrite, and their levels increase with the date of storage. Nitrite is a strong carcinogen, and regular consumption of leftovers increases the risk of cancer.

4. It is easy to get stomach problems. Because of repeated heating, the starch in leftovers is difficult for the human body to digest. Long-term consumption of this reheated leftover rice is very likely to cause stomach problems.
