Things can't be absolute! Leftovers can be eaten, and if all the leftovers are thrown out, isn't it a waste?!! But it's not about blindly eating leftovers, but also paying attention to your health, especially in summer.
Let's talk about leftovers: The storage time of leftovers is advisable not to eat between meals, eat in the morning and lunch, and eat in the afternoon and evening, try to solve it within 5 or 6 hours, and it is best not to eat overnight dishes. 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). If it's winter, some families think that the weather is cold and leftovers don't need to be put in the refrigerator, which is also wrong. Now, the widespread use of refrigerators in cities has reduced the nitrite content of people's intake from food, but it does not mean that vegetables can be put in the refrigerator with complete confidence; Over time, the nitrite content will still increase.
It is worth mentioning that the amount of nitrite produced by different types of vegetables under the same storage conditions is not consistent. 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!

Even if the leftovers do not taste good, bacteria will multiply, which can easily cause intestinal diseases.

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 definitely be eaten if they cause cancer.
Leftovers often have nitrite excess. Nitrite itself is toxic and meets proteins in the stomach to produce nitrosamines, a carcinogen. Some data show that 80% of the nitrite intake comes from vegetables. >>>More

The main ingredient in commonly eaten rice is starch, which is hydrolyzed into dextrin and maltose by salivary amylase in the mouth. After entering the small intestine through the stomach, it is broken down into glucose, which is then absorbed by the intestinal mucosa. When starch is heated above 60, it gradually expands and eventually becomes a paste, a process called "gelatinization". >>>More
