Eight Overnight Foods Remember to Never Eat
It is a virtue not to waste food. To avoid wasting food leftovers, many people left the leftovers to enjoy them tomorrow. However, not all foods can be overnight.
1, overnight tea can not drink overnight tea For too long, most of the vitamins have been lost, and the tea in the protein, sugar, etc. will become bacteria, mold breeding nutrients, so people often think that overnight tea can not drink. 2. Can the white fungus be eaten overnight? Tremella soup is an advanced nutritional supplement, but once overnight, the nutrients will be reduced and harmful ingredients will be produced. Because both the white fungus grown indoors and the tremella cultivated in the wild have a lot of nitrates, such as the release of a long time after cooking, under the decomposition of bacteria, nitrate will be reduced to nitrite. When people drink this kind of soup, nitrous acid naturally enters the blood circulation, hemoglobin in the red blood cells in the blood, and can carry a large amount of oxygen for the body's needs.
However, nitrous acid reacts counter-productively, causing the normal hemoglobin in the human body to oxidize to methemoglobin, losing the ability to carry oxygen and causing the body to lack normal hematopoietic function!
3, can not drink boiling water overnight? The tap water to boil 3 to 5 minutes, nitrite and chloride and other harmful substances in the lowest content, the most suitable for people to drink. Drink less water overnight: Nitrite can form carcinogenic nitrosamines in the human body. Some experts have found that the nitrite content in boiling water is higher than raw water. In addition, the boiled water that has been boiled for too long or over 24 hours repeatedly has a significant increase in nitrite content. After 24 hours of boiling water, the nitrite content was 1.3 times that immediately after boiling. Our residents have a habit of drinking and drinking water. It is best to drink or drink only on the same day. Do not drink boiled water for too long.
4. Can't eat overnight eggs? Overnight eggs, can you eat it? Northerners: Yes, you don’t see tea and eggs selling through the streets! Southerners: No, especially men, because they’ll get intestinal gas, scrotal swellings! Scientists: Not necessarily! Because the eggs are not fully cooked, the unripe egg yolks will be eaten overnight. Under improper storage conditions, nutritious foods will be prone to bacterial growth and will be harmful to health, such as causing gastrointestinal discomfort and flatulence. However, if the food (egg) is cooked and stored properly at a low temperature (usually refrigerated), it can generally be stored for 48 hours without problems. From the scientists’ tips, we can know: Eggs can not be eaten overnight, not only to see whether it is heated, but to cook the eggs for the first time, only cooked eggs for the first time. After that, it is no problem to cook it overnight.
Tea leaves are just like this. Maybe we don't know that the tea eggs are boiled twice and cooked for the first time. The second time, the egg skin is broken and the tea and other accessories are added to cook. So the tea eggs are definitely cooked. Now, some people love to eat medium rare eggs (the egg yolks are semi-liquid). The eggs cannot be eaten overnight. Even if cooked for the second time, don't eat them.
5, do not eat overnight vegetables! As some green leafy vegetables contain more nitrates, if placed too long after cooking, in the decomposition of bacteria, nitrate will be reduced to nitrite, there are Carcinogenic, heating can not be removed. Usually, the nitrate content of the stem and leaf vegetables is the highest, the melon vegetables are slightly lower, and the root vegetables and the cauliflower are middle. Therefore, if you purchase different types of vegetables at the same time, you should eat stems and leaves first, such as Chinese cabbage, spinach and so on. If you are going to cook more vegetables for the next day, you should try to do as little vegetables as possible and choose melon vegetables instead.
6, the family lo Mei bad goods do not eat lo mei overnight and bad goods are Shanghai residents like to eat seasonal dishes, many people also like to eat the rest of the miscellaneous Mei bad food refrigerator "overnight", but this approach has great Food safety hazards. To prevent food poisoning, don't eat bad foods in the spring and summer. Bulk and lo-mei are to be eaten on the same day and cannot be overnight. From the perspective of food safety, this is unsanitary, and it is best not to eat overnight if possible.
Food experts warn that even food in the refrigerator is not absolutely "safe." Easy to mold mold in the refrigerator, as well as psychrophilic bacteria.
7, overnight seafood products can not be eaten overnight, there are fish, seafood, green leafy vegetables, salad and so on. Fish and seafood are prone to protein degradation overnight and can damage liver and kidney function. Green leafy vegetables contain different amounts of nitrates. Over- or over-cooking takes too long. Not only will the vegetables yellow and turn off, but nitrates will also be reduced by bacteria to toxic nitrites, causing cancer. Cold dishes have been contaminated during processing, and even if they are refrigerated, they are likely to have deteriorated overnight and should be freshly made.
8, how to do overnight soup? Cantonese people like soup, drink soup in the refrigerator, the next day boiled and then drink. This kind of overnight soup is good for your body? Healthy eating method: The best way to preserve the soup is not to add salt and other seasonings. Cook the soup and use a clean spoon to drink the same day. It's good to store it in the fridge with a pot. Because the remaining soup is held in aluminum pans and stainless steel pans for prolonged periods, it is prone to chemical reactions and should be placed in glass or ceramic ware.
