Chinese do not stick to the sub-section, like the atmosphere and boldness, especially when cooking, every time you have to do a little more, you can be left, but resolutely can not be enough.
When many families have leftovers, they will save the next meal, especially in the evening, and may be eaten until the morning of the second day, so as to save breakfast.
Is it really true that leftovers are carcinogenic? Especially the staple food - rice, many families have a large population, after the staple food is more likely to appear leftovers, so many people will choose to make egg fried rice the next day, can this be eaten in the end?
Will secondary heating of rice be "carcinogenic"?
Many people think that the secondary heating of rice will cause cancer, because rice stored in the refrigerator for a long time will breed a lot of bacteria and microorganisms, the second heating, if not fully cooked, it is easy to cause viruses and bacteria not to be eliminated in time, affecting human health.
Some people think that this is because rice produces a large amount of nitrite after being left overnight, and excessive intake can easily lead to cancer. In fact, not all foods produce this substance, usually occurs in packaged or succulent foods, do not have to panic and be afraid.
Rice heated twice is easy to cause cancer, in fact, only put for a long time of rice has proliferated, bacteria and viruses have occurred, metamorphism or heating may produce some nitrite, and then react with gastric juice, easy to produce carcinogens.
In general, rice does not breed too many bacteria when stored, nor does it bring nitrites, and besides, everyone knows that putting aside the toxicity of the dose bomb, this is inorganic and has no scientific basis.
Nitrite only reaches a certain level will cause harm to health, under normal circumstances, the content of nitrite in leftovers will not cause too much harm to health, as long as people do not eat a lot for a long time, there will be no problem.
Therefore, the rice after the second heating will not cause cancer, and you can usually eat a little properly, but you must also control the number of times.
Doctor's advice: These 6 kinds of food, it is best not to reheat
(1) Fungal foods
When it comes to fungi, the first thing that comes to mind is mushrooms, mushrooms after high temperature cooking, will produce a lot of nitrate, especially seafood mushrooms, apricot abalone mushrooms, shiitake mushrooms, in the refrigerator low temperature storage and secondary heating process, nitrite content will continue to increase.
Often after the second heating to eat mushrooms may cause abdominal pain, diarrhea and other symptoms, long-term eating, will increase the probability of suffering from digestive system tumors, so after the second heating is not recommended to continue to eat mushrooms, try to eat once, eat can not finish throwing away.
(2) Seafood food
Shrimp, crab, flower shell and other seafood foods are not suitable for secondary heating, if the uneaten seafood is placed for too long, it is easy to breed bacteria and produce toxins, but the usual heating time and temperature are difficult to kill and eliminate these bacterial toxins, increasing the detoxification burden of the liver, it is best to eat now.
(3) Spinach
Spinach has a high content of oxalic acid, which needs to be boiled before eating, in addition, spinach also contains a lot of nitrate, if heated twice, spinach reheating will be converted into nitrite, harmful to the human body.
(4) Milk
Milk can not be repeatedly heated, a long time will deteriorate, thereby breeding bacteria, easy to cause diarrhea, in addition, milk repeated heating will make the milk protein denaturation, resulting in nutritional deficiencies, the boxed and bagged milk on the market are sterilized or disinfected, can be drunk directly, can also be heated to drink, do not cook thoroughly, do not repeatedly heat.
(5) White fungus soup
Because white fungus contains more nitrate, if cooked silver ear soup is placed for too long, it will decompose, reduce nitrate to nitrite, nitrite will make the hemoglobin in the blood lose its ability to carry oxygen, thereby destroying the normal hematopoietic function of the human body and affecting health, so it is best to drink it freshly, not overnight.
(6) Loose heart eggs
The egg mainly refers to the undercooked egg, so the cooked egg does not completely kill the salmonella in the egg, if left for another night, the chance of bacterial reproduction and toxin production will increase, even if it is cooked for the second time, there will be a risk of disease, it is best to avoid eating.
Occasionally eating a small amount of eggs may not bring obvious harm to human health, but if excessive consumption or frequent consumption of eggs, it may lead to gastroenteritis, abdominal pain, diarrhea, nausea and other symptoms, and even cause food poisoning in severe cases.
Eggs are best eaten cooked thoroughly, so that the bacteria inside can be destroyed, and fully cooked eggs are stored at low temperatures and sealed conditions, and generally maintained for 48 hours is no problem.
How can you make a meal stay the same?
◆ You can store the meal in the refrigerator first, so that the meal will not easily spoil at low temperatures.
◆ Add an appropriate amount of cold water to the basin, and then place the container containing the food in the cold water basin, and cover the basin with a ceramic container, so that the food will not become sloppy after the temperature is reduced.
◆ First add an appropriate amount of table salt to the basin to form a concentrated salt solution, and then place the food in the concentrated salt solution and cover the head of the gout.
◆ When cooking rice, you can add an appropriate proportion of vinegar, so that the cooked rice storage will not easily become sloppy.
◆ After the leftover rice is boiled with water, it is not necessary to open the lid of the pot after boiling, do not shake, and then place it in a cool and ventilated place, which can ensure that the food will not become bad overnight.
