Hello everyone, the Chinese New Year is full of food, friends enjoy a table of delicious food, and the problems that come with it are also annoying, such as a large number of leftovers. Leftovers tend to grow all kinds of bacteria, especially E. coli and Salmonella, at room temperature. These bacteria can cause food poisoning and affect human health. In addition, leftovers that have been reheated repeatedly will affect their nutrients and taste, and long-term consumption is not good for health. Several studies have shown that regular consumption of leftovers increases the risk of diseases such as stomach cancer, liver cancer, etc.
Some people say that if you keep leftovers in the refrigerator, won't bacteria be produced? In fact, the refrigerator is also a reservoir of bacteria! Although the temperature of the refrigerator is low, it stores all kinds of food on a daily basis, and the flavors inside are mixed, which is the most likely to breed bacteria. Therefore, putting leftovers in the refrigerator does not guarantee the freshness of the food, but rather aggravates the spoilage of the food.
EspeciallyThe 5 foods left over during the Chinese New Year cannot be eaten in the refrigerator, hurts the liver and stomach, everyone must remember, don't get sick during the New Year!
1. Green leafy vegetables
Green leafy vegetables contain a lot of nitrate, and if left for too long after cooking, the nitrate will be reduced to toxic nitrite by bacteria. Nitrite is a potential carcinogen that can affect human health when it enters the human body.
When green leafy vegetables are left for too long, the vitamin C and antioxidants in them will be gradually lost, further reducing the nutritional value and edible value of vegetables.
If you eat leafy greens that have been left overnight, it may cause diarrhea, headaches, nausea and other uncomfortable symptoms, and long-term consumption may also increase the risk of cancer. Therefore, it is recommended to eat cooked leafy greens as soon as possible in a short period of time, generally no more than 2 hours.
In order to ensure the safety and health of food, it is recommended to choose fresh, green vegetables as much as possible and avoid eating vegetables that have been left overnight. If you need to preserve fresh vegetables, you can take some preservation measures, such as sealing them in a plastic bag and putting them in the refrigerator to reduce bacterial growth and oxidation of vegetables.
2. Seafood
Seafood is rich in protein, and the protein in cooked seafood is broken down into amino acids, which are further broken down during overnight sitting, producing harmful substances. These substances include amines, ammonia, etc., which are harmful to human health.
In addition, when seafood is cooked, bacteria are more likely to grow, vitamin C and vitamin B groups will also decrease, and the taste of food will deteriorate and become strange.
Eating seafood overnight can cause nausea, vomiting, abdominal pain and diarrhea in mild cases, and food poisoning, gastrointestinal cramps, vomiting and diarrhea in severe cases.
To ensure food safety and nutritional value, it is recommended to eat cooked seafood as soon as possible. In general, it is best to eat cooked seafood within 1-2 hours.
3. Soup
When the soup is left overnight and heated repeatedly, it is prone to nitrite, which is a harmful substance that may affect human health if consumed for a long time. Secondly, after a long period of storage, the nutrients in the soup may be broken down or lost, resulting in a decrease in nutritional value.
There are two main aspects of the possible harm to the human body from the consumption of overnight soup: First, nitrite may be converted into nitrosamines in the human body, which is a carcinogen that may increase the risk of cancer.
Secondly, the nutrients and taste in the soup may change, affecting the taste and appetite, which in turn can affect the health of the body. In order to maintain the nutritional value and taste of the soup, it is recommended to consume it as soon as possible after the preparation is completed.
Fourth, hot pot
The ingredients in the hot pot are abundant, rich in nutrients such as proteins, vitamins, and trace elements, which can change at high temperatures and produce harmful substances. If the hot pot is left overnight, the soup base and ingredients may deteriorate, breeding bacteria, mold and other harmful substances, which will affect human health. In addition, ingredients such as meat and seafood in hot pot will produce purine substances after cooking at high temperatures, and these substances will also deteriorate during long-term storage.
Although refrigerators can play a certain role in preserving freshness, they cannot completely prevent the growth of harmful microorganisms. If the hot pot is left in the refrigerator for a long time, it will cause the oil, seasonings and other ingredients in it to gradually deteriorate, resulting in abnormal phenomena such as odor and discoloration.
In addition, the oil, seasonings and other ingredients in the hot pot will also deteriorate during the long-term storage process, resulting in abnormal phenomena such as peculiar smell and discoloration, which may contain harmful substances such as bacteria and mold. These harmful substances can cause certain harm to human health, such as diarrhea, vomiting and other symptoms.
5. Soy products
Soy products themselves are fermented soybeans, and if they are left overnight after cooking, the microorganisms inside them may destroy the nutrients of the soy products and cause them to spoil. If soy products are left in a high temperature environment for too long, it will be more likely to cause bacteria to multiply and deteriorate, which will lead to sourness, taste, and soft texture. These microorganisms may produce harmful substances through metabolism, such as hydrogen sulfide, methamidophos and other harmful substances, causing harm to human health.
The reason why soy products can also spoil when stored in the refrigerator is mainly due to the reproduction of microorganisms. The temperature of the refrigerator, while slowing down the growth of microorganisms, does not completely prevent them from multiplying. In addition, moisture in the refrigerator may penetrate into the soy products, making them moist and soft, which also provides conditions for the growth of microorganisms.
When soy products deteriorate, some harmful substances may be produced, such as amines, hydrogen sulfide and other harmful substances. The harm of these substances to human health mainly includes irritation of the gastrointestinal tract, causing diarrhea, vomiting and other uncomfortable symptoms, and in severe cases, it may also lead to food poisoning. If you find that the soy product already has a strange smell, it means that it has deteriorated and you should stop eating it immediately.
The food during the Chinese New Year is abundant, and I hope that everyone can enjoy the food while also paying attention to healthy eating and protecting their health. Let's work together for a healthy life!
Today's food is shared here, everyone remember to follow, like, watch, and learn more about healthy food every day
