On New Year’s Eve, the whole family sits around the table and gossips. Naturally, there is a big dinner. However, as the Spring Festival approaches, while people are ready to enjoy the delicious food, all kinds of rumors about food are beginning to stir up: "I heard that chicken chops contain meat glue and can’t be eaten!" "Don’t you know? Fish belly is poisonous! " "Alum is used for fried melon seeds, so buy it carefully." … … Under many rumors, everyone was inevitably affected and began to panic. "You can’t eat this or that. How can you spend this year?"
Chicken chops with minced meat, poisonous fish maw and alum melon seeds … … How many of these rumors are true? How much is alarmist?
Does the chicken steak contain meat glue? Edible within the standard range
In recent years, delicious chicken chops have gradually become the new favorite on the New Year’s table. Compared with chicken, chicken chops are more beautiful in appearance, convenient to cook and rich in taste, and also avoid the trouble of removing bones on the dining table. But from the beginning of popularity, chicken chops seem to have their own "topics". Many people think that chicken chops are not natural products, but are synthesized with meat glue in the later stage and cannot be eaten at all.
What is meat glue? Is the meat glue in the chicken chops brought by the chicken or added during the production process? Are chicken chops really inedible?
"Meat glue is actually an enzyme, the scientific name is glutamine transaminase, which can make protein molecules form sponge-like ‘ Network crosslinking ’ Structure. The meat stuck together by it, in appearance ‘ Perfect ’ It will not be dispersed during cooking and processing, and the taste will be better. " Zhang Tian, nutritionist in charge of clinical nutrition department of Aviation General Hospital of China Medical University, told the Science and Technology Daily reporter.
According to GB2760-2011 "Standard for the Use of Food Additives", glutamine transaminase, also known as meat glue, is a stabilizer and coagulant, and the maximum dosage is 0.25 g/kg.
Zhang Tian said that the chicken chops we usually eat are very large. Of course, this is not taken directly from the chicken, but we need to integrate different sizes of chicken with meat glue.
"So chicken chops do contain meat glue, and how much meat glue is contained in chicken chops often depends on the merchants at present." Zhang Tian added, "The market supervision standard for producing big chicken chops with meat glue as an additive is not clear at present, but we can temporarily refer to the standard of bean products. In short, eating too much chicken chops containing meat glue is definitely not good for your health. "
Not only chicken chops, but also other meats on the table, everyone needs to be temperate.
Is the "black film" of fish belly poisonous? It’s no problem to eat at ease
People give the beautiful meaning of "more than one year" to the fish dishes on the table. On the New Year’s Eve table, fish is an essential dish. Recently, it has been said that "a layer of black film on the belly of fish gathers all kinds of toxic substances in the belly of fish, which will be poisoned if eaten".
This rumor makes many people wonder, "have I eaten poisonous fish for so many years?" Do you eat fish or not? "
In this regard, Zhang Tian said that this statement is unreliable. "The black membrane on the fish belly is called peritoneum, which exists between the abdominal wall and internal organs of the fish and is a normal physiological structure." Specifically, peritoneum refers to a layer of mucosa existing in the abdominal cavity of some vertebrates. It wraps most of the organs in the abdominal cavity, and can secrete mucus to wet the surface of organs, reduce the friction between organs and reduce the damage to internal organs caused by impact.
Not only fish, but also other animals have such a film on their bellies. So, why is this film black and looks like poison? Zhang Tian explained that the color of the film is related to the pigment of the fish itself. Not all the films on the belly of the fish are black, and some are light or colorless.
Obviously, the color of fish belly membrane can not be used as a criterion to judge whether fish is poisonous or not. The view that eating the black film on the belly of fish will lead to poisoning is not credible. It seems that this year’s Spring Festival, "fish every year" can continue to be served on the table.
Drinking in the cold in winter? Drinking too much makes you feel cold.
During the Spring Festival, when friends and relatives get together, it is inevitable to have a few drinks. Recently, there seems to be a lot more rumors about alcohol.
Drinking is harmful and not beneficial? People who like drinking have different views. They insist that drinking can keep out the cold, and fever after drinking is the best proof.
In this regard, Zhang Tian believes that a small amount of drinking does have a certain cold protection effect. "After drinking, the liver metabolizes alcohol substances, and it takes a long time to decompose alcohol, and more calories are produced. At the same time, alcohol stimulates blood vessels and dilates them. Therefore, after drinking, the blood circulation speed in the body is accelerated, the breathing rate is increased, and the heat such as muscles and internal organs is more easily transmitted from the blood to the skin on the body surface, and people will naturally feel obvious fever. "
But everything goes too far. After drinking too much, it is easy to cause the loss of heat in the body, which makes people feel cold.
"Excessive drinking can cause damage to the liver, brain, nervous system and digestive system." Zhang Tian advised everyone to limit drinking during the Spring Festival, try not to drink high-alcohol and moderate-alcohol wine. Don’t refuse to come because you are happy or "face". Drunkenness and alcoholism are easy to hurt yourself, and those with bad drinking style may even hurt people.
Eating durian after drinking causes blood vessel blockage? There is no such thing
Near the Spring Festival, there are many rumors about alcohol, and not drinking while eating durian is one of them. Eating durian and drinking alcohol at the same time is more harmful to diabetic patients, which will lead to blood vessel blockage, and serious blood vessel burst and stroke may occur.
Regarding the statement that "you can’t eat durian after drinking", Zhang Tian said that there is no basis. Whether eating or drinking a certain food after drinking alcohol will cause harm to health must be based on crowd experiments or epidemiology. At present, no relevant research conclusions have been seen. At present, the medical community is more recognized that only after drinking alcohol can you not take antibiotics, antihypertensive drugs and so on.
Zhang Tian also explained whether diabetics can drink and eat durian. "Diabetes patients who drink and eat durian at the same time will not cause blood vessel blockage. Even if this happens, it may be that such people themselves have bad eating and living habits, which may be accompanied by dyslipidemia."
Even so, Zhang Tian does not recommend eating durian while drinking. "This will lead to excessive calorie intake and single nutrients, which will easily cause blood sugar fluctuations."

Drinking tea after drinking hurts the kidneys? Strong tea has certain influence.
In addition to eating durian after drinking, drinking tea after drinking seems to have become the "attack range" of online rumors. All online platforms "Health School" agree that drinking tea after drinking will cause kidney damage. Is there any scientific basis for this statement?
Zhang Tian believes that this should be analyzed according to the specific situation.
"Drinking strong tea after drinking will have a certain impact on the kidneys, and light tea has little effect." Zhang Tian said that tea contains theophylline, which has diuretic function, so that the metabolites of alcohol in the process of liver detoxification, such as acetaldehyde, can directly reach the kidney before being converted into water and carbon dioxide. As a harmful substance that can stimulate the kidney, acetaldehyde can cause kidney damage. (Intern Ge Junxia, reporter Chen Yu)
