It takes 32 days to detoxify a pack of instant noodles? Eating too much causes cancer? These 4 foods are really carcinogenic
A foreign scientist has used capsule endoscopy to film the situation of instant noodles and hand-pulled noodles entering the human body, and compared them.
The results showed that the hand-pulled noodles could be completely digested in the human body after 32 hours, while the instant noodles remained.
There are still many news reports about instant noodles. It is reported on the Internet that a female college student eats and rests irregularly for a long time, and does not pay attention to stomach pain. She ate instant noodles for a month before the exam. , found to have advanced gastric cancer.
Does "instant noodles" really have a lot of food additives? Do you really eat a pack of detox for 32 days? Is it really that unsafe? Xiao Jiu explained it all today!
1. Is instant noodles "made" by food additives?
It is rumored that there are many additives in instant noodles, and it takes 32 days to detoxify after eating one packet.
In fact, this statement is not scientific. Although there are indeed many food additives in instant noodles, such as sodium hexametaphosphate, sodium bicarbonate, sodium benzoate, etc.
However, food additives are not illegal additives. As long as they are used and added according to the use category and addition limit of food additives, they are safe and will not cause harm to the human body. The food additives added to instant noodles produced by regular manufacturers are legal and compliant.
And illegal additives, such as melamine, clenbuterol, etc., are harmful to the human body.
The claim that the liver needs to be detoxed for 32 days is also made out of nothing. As long as it is a qualified product, it can be eaten with confidence, and it can be excreted by normal human metabolism . At the beginning of the article, the scientist's original intention was to observe the digestion process of food, but it was later misunderstood as the rumor that "instant noodles are not digested for 32 hours".
2. If you eat too much instant noodles, will you get cancer?
Instant noodles are not only classified as "junk food", but also rumored to cause cancer.
Starchy foods may produce acrylamide at temperatures greater than 120 degrees Celsius .
Acrylamide has been confirmed to be a carcinogen by in vitro cell experiments and animal experiments, but there is currently insufficient population epidemiological evidence to confirm that there is a significant correlation between the occurrence of a certain tumor in humans and acrylamide in food.
Acrylamide is also only known as a Class II carcinogen, that is, the evidence for carcinogenicity in humans is unclear.
Bian Dongsheng, a nutritionist from the Clinical Nutrition Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine, once said,Relevant experiments have shown that the detection value of acrylamide in instant noodles produced in China is about 0.5~2.89μg/g, which is relatively low compared to other French fries and oil cakes.
According to the findings of the New Jersey Food Specialist, no adverse effects were observed in humans at dietary intakes of 0.1 mg/kg body weight of acrylamide per day.
The relevant officials of WHO food safety also believe that the level of acrylamide ingested by the human body is still difficult to reach the level of harm to health.
Therefore, instant noodles cancer is also "created out of nothing".
3. Therefore, instant noodles are not junk food, these claims are false
Instant noodles have been labeled as " junk food ", and many other rumors have been made about them. In fact, they are all misunderstood.
1. Will the paraffin in the instant noodle box dissolve?
The inside of the instant noodle box contains a layer of film, which is mainly to resist the immersion of high temperature boiling water. Some people look at the shiny appearance of the film and mistakenly think that the film is made of paraffin. In fact, the film is a polyethylene coating with a melting point of 110°C, which will not dissolve even when soaked in boiling water.
2. Are instant noodles fried in "thousand rolls of oil"?
The oil used for repeated heating is called "Qianzhuan oil". Although in the food processing industry, there may be unscrupulous merchants who use Qianzhuan oil or add excessive antioxidants in order to save costs. In the process of repeated heating, harmful substances may be produced. .
But at present, the instant noodles on the market are strictly controlled by food safety, and there will be no case of thousands of oil. If you are really worried, choosing non-fried noodles is also a good choice.
3. Instant noodles contain palm oil, is it "bad oil"?
It is a common practice in the world to make instant noodles with palm oil . The average oil content per serving of instant noodles is around 16%-18%, of which about 11% is palm oil.
Taking a hamburger as an example, the average fat is about 30%, which is twice as high as that of instant noodles. Edible palm oil has been used as a natural food for more than 5,000 years, and the food safety standards established by the International Codex Alimentarius Commission also confirm that palm oil is a safe edible oil.
4. These 4 kinds of really carcinogenic foods should be eaten or eaten less
To say that the biggest problem of instant noodles may be that they have more fat and less nutrition. When it comes to really carcinogenic foods, the following are few to touch.
1. High temperature fried food
Fried food may produce carcinogen benzopyrene, and the content of benzopyrene produced by burnt food is 10 to 20 times that of ordinary food. Long-term intake of large amounts of foods containing benzopyrene increases the risk of cancers such as stomach and rectal cancer.
2. Pickled food
Preserved foods such as sausages, smoked fish, and salted fish may have excess nitrite. Although nitrite is not carcinogenic, if it reacts with protein metabolite amines in food to form nitrosamines, in excess, it will increase the risk of cancer.
In addition, nitrite can combine with hemoglobin after entering the human body, which may cause blood oxygen poisoning in the human body, and may even cause death in severe cases.
3. Moldy food
Moldy foods may produce aflatoxin, a strong carcinogen. Ingestion of large amounts of aflatoxin may cause acute poisoning, causing severe liver damage, and exposure to even small doses can increase the risk of liver cancer. So must not eat moldy food, and pay attention to food storage.
4. Hot food
A study published by the International Agency for Research on Cancer found that people who habitually drink hot beverages have a higher risk of developing esophageal cancer.
Ling Yiqun, deputy chief physician of the Nutrition Department of Fudan University Affiliated Cancer Hospital, said that the normal temperature of the oral cavity and esophagus is about 37°C. Long-term exposure to food around 75°C may slightly burn the oral mucosa, cause chronic inflammation of the esophageal mucosa, and increase esophageal cancer. probability.
Food safety is closely related to our health. Eating instant noodles in moderation will not cause harm to the body. We must put an end to bad rumors about instant noodles. In addition, please do not eat or eat less of the 4 kinds of foods that the article exemplifies that are really at risk of cancer .
