A healthy baby/happy family
Hand care/care for children
Looking forward to it, the Dragon Boat Festival holiday is coming! Finally, the children in the school put down the homework they had been holding all day, and their parents also put down their mobile phones and invited their grandparents who had not seen each other for a long time to get together and have dinner!
As long as there are old people at the dinner table, it is inevitable to be saved by nagging. For example, if you eat all the rice, don't waste a grain of rice, and don't live up to the hard work of the farmer's uncle; For example, buy less meat and vegetables in the future, and you can't finish it. These are all instilled by the previous generation, and we want to listen. But I can't stand one thing. I can't pour leftovers. Can I eat when the weather is hot tomorrow? ! In fact, as long as it is more than 8 hours, you can't eat it.
Guide: Don't eat overnight. 1, green leafy vegetables are the most dangerous overnight; 2. Overnight seafood damages liver and kidney; 3. It is dangerous to put eggs for a long time; 4, tremella mushrooms should be cautious; 5. Don't put metal utensils in the soup for the night; 6. Don't eat overnight; 7.

After summer, the temperature rises, bacteria become active, and intestinal diseases enter the high-incidence season. Some dishes may be more poisonous than arsenic after a night. Wang Shizhen, director of the Department of Pediatric Critical Care Medicine of Fujian Maternal and Child Health Hospital, reminded that many elderly people are very frugal and unwilling to throw away leftovers. In other families, the food is not finished, and parents don't even wrap it in plastic wrap, so they just put it in the refrigerator, and it's not hot enough when they eat it again. This practice has great health risks, especially in summer.
Don't eat overnight
1) Green leafy vegetables are the most dangerous overnight.
Usually, the nitrate content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, and roots and cauliflower are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables, such as Chinese cabbage and spinach. If you are going to cook more vegetables and eat them hot the next day, try to make fewer stem and leaf vegetables and choose melons.
Knock on the blackboard to remind! ! ! It's summer. If you haven't finished eating green leafy vegetables, don't stay overnight. No matter how painful it is, please empty the trash can, especially spinach and celery, which have high nitrate content and can be easily converted into nitrite after reheating, and nitrite is a very dangerous carcinogen.
2) Overnight seafood damages liver and kidney.
Seafood such as crab, fish and shrimp will produce protein degradation products overnight, which will damage liver and kidney functions. If you really buy too much, you can put raw seafood in a fresh-keeping bag or box, freeze it in the refrigerator and cook it next time.
3) It is dangerous to leave eggs for a long time.
Many people like to eat half-cooked eggs, but this kind of eggs is not completely sterilized, and the eggs are rich in nutrition, which is particularly easy to breed bacteria and will be dangerous to eat. Therefore, it is best not to eat eggs overnight, that is, to cook them immediately.
4) Beware of tremella mushrooms
Whether it is wild or cultivated tremella, mushrooms, etc. It is easy to leave a lot of nitrate. If you leave it for a long time, you can only throw it away reluctantly, otherwise it may cause gastrointestinal discomfort.
5) Don't put metal utensils in the soup overnight.
Boiling soup takes time and effort. People often cook a large pot and eat it for several days. If the leftover soup is left in aluminum pot and iron pot for a long time, it will precipitate substances harmful to human body. The best way to preserve soup is not to put seasoning such as salt in the soup. After the soup is cooked, put out what you want to drink that day with a clean spoon, and it is best to store it in the refrigerator with a clay pot or a fresh-keeping box.
6) Don't eat braised pork overnight.
To prevent food poisoning, don't eat stewed vegetables overnight in spring and summer. Even the food in the refrigerator is not absolutely safe. Refrigerators are prone to mold and psychrophilic bacteria.
7) Don't drink soy milk overnight.
Freshly squeezed soybean milk has a short shelf life and must be drunk within 2-4 hours at room temperature, otherwise the number of colonies will increase sharply, causing deterioration! It is best to squeeze and drink it now, or to cool the cooked soybean milk and put it in the refrigerator for sealed preservation to prevent deterioration. Freshly squeezed soybean milk refrigerated in the refrigerator should not be stored for too long, and it is best not to drink it for more than 12 hours.
8) Don't eat potatoes overnight
Potatoes are a good thing, but they can't be heated overnight, which will not only cause the loss of nutrients in potatoes, but also damage our health.
Safe eating rules of vegetables overnight
Besides these overnight dishes, other dishes can still be eaten overnight. How to deal with it is the healthiest and safest?
1) Put it in the refrigerator immediately after it is completely cooled.
It is because hot food suddenly enters a low-temperature environment, and the hot air of food will condense water vapor, promote the growth of mold, and lead to moldy food in the refrigerator. After thorough cooling, put it in the refrigerator in time, even in winter, and don't leave it outside for a long time, because the refrigerator has certain antibacterial effect.
2) Different leftovers are stored separately.
Separate storage can avoid bacterial cross-contamination. It also needs to be sealed in a clean container, such as a fresh-keeping box, a fresh-keeping bag, or a layer of plastic wrap for the vegetable bag.
3) Do not add seasoning to the soup stored overnight.
If the soup is to be preserved overnight, the best way to preserve it is not to season it with salt. After the soup is cooked, scoop out the amount you want to drink that day with a clean spoon, and store the rest in the refrigerator with a clay pot. The leftover soup is stored in aluminum pot and stainless steel pot for a long time, which is prone to chemical reaction and should be stored in glass or ceramic utensils.
4) Heat thoroughly before eating.
Besides reasonable storage, reheating is also the key to ensure health. Leftovers are stored in the refrigerator. Before eating, be sure to return to the pot at high temperature, heat the whole dish to 100℃ and keep boiling for more than 3 minutes. Because low temperature can only inhibit bacterial reproduction, it can't completely kill bacteria.
5) Eat in two days.
Studies have shown that the nitrite content of leftovers will rise linearly if they are left at room temperature for more than 6 hours. Even if it is placed in the refrigerator, the refrigerator only plays a bacteriostatic role and cannot be sterilized. Bacteria will still grow and grow slowly. Leftover food can generally be eaten within 2 days, and it is best to throw it away after 3 days. Usually, the leftovers in the freezer will not go bad for two weeks, but it is also recommended to eat them within one week.
6) Clean the refrigerator regularly.
Many household refrigerators are not cleaned regularly, and all kinds of bacteria (especially Escherichia coli) will breed in a humid and cold environment. Take out the frozen food and eat it immediately. Bacteria can invade the gastrointestinal tract, causing "refrigerator gastroenteritis". So, in about three months, the refrigerator will be cleaned.
