"Non-fried" food is very healthy, can you eat open? Don't be fascinated by these "pseudoscience" gossips

Original title: At the end of the year, don't be fascinated by these "pseudoscience" rumors
2020 is coming to an end, but the rumors are still not over: this winter will be the coldest winter in 60 years, eating bubble food will cause poisoning, "anti-heliosterol" can kill Helicobacter pyridosis, security device radiation will harm fetal health, air fryer easy to cause cancer ... Are these rumors true or false? Recently, by the Beijing Science and Technology Association, Beijing Internet Trust Office and other newly released "monthly 'science' gossip list", to help everyone debunk these "pseudoscience" gossip "true face."
Fest 1: This winter will be the coldest winter in 60 years
Truth: Yan Yu, a meteorologist with the China Meteorological Administration, explains that "La Nina" refers to the widespread and persistent abnormal cooling of the waters in the eastern and central equatorial Pacific Ocean. When the duration of the low temperature phenomenon reaches a certain level, it is called a "La Nina" event. This winter will be cold or warm, need to be based on scientific analysis of comprehensive research, not through a few snow can be judged.
" whether it is cold winter or warm winter, there are pros and cons. For example, a warm winter is good for the survival of bacteria and viruses in the air, increasing our chances of getting sick. Due to the higher temperature, the probability of snowfall is greatly reduced, resulting in exceptionally dry weather, soil eggs are more likely to winter breeding, or lead to large-scale insect disasters, not conducive to agricultural production. However, the temperature is not so cold, heating demand will be relatively reduced, conducive to energy conservation. The incidence of cardiovascular disease increases significantly during the winter when temperatures plummet or are particularly cold, he said. Therefore, during the cold winter, special attention should be paid to the health of people with hypertension or cardiovascular disease.
Gossip 2: Anti-blu-ray glasses can prevent damage to the eyes of electronic screens and myopia
Truth: First of all, due to part of the anti-blu-ray glasses yellowing, for children in the growth and development period, may affect their visual development, children are not recommended to wear anti-blue light eyes daily. Second, anti-blue light does not mean anti-myopia. There is no direct evidence of myopia caused by blue light, and there is no need to worry too much about the so-called "blue light hazard". In addition, adults do not need additional anti-blu-ray measures.
If you experience symptoms such as visual fatigue, you can protect your eyes by reducing continuous eye time, using electronics before bedtime, avoiding playing with your phone and reading in poor background light, and looking out for rest every 20 minutes.
3: "Anti-Helicobacter pythroids" can kill Helicobacter pyrethroids
Truth: infection with Helicobacter pyrethroids does not necessarily mean that you will get stomach cancer. Studies have shown that only 1% of people infected with Helicobacterrobacteria develop stomach malignancies. At the same time, Helicobacteria prefers to grow in the sinuses of the stomach, not the mouth, toothpaste does not act in the stomach at all. The so-called "anti-claustrophobic toothpaste" neither play a preventive effect, nor can it be sterilized, purely commercial speculation.
Gossip 4: "Desaccharged rice cooker" cooking can reduce 70% of the sugar in rice
Truth: Beijing Institute of Nutrition Sources experts on the "desaccharged rice cooker" and ordinary rice cooker cooked rice double-blind determination, experimental results show that the rice cooked by two rice cookers, into the human body after the formation of blood sugar is virtually no difference. Carbohydrates in food are divided into monosaccharies, polysaccharies and polysaccharies. Starch is a kind of polysaccharose, need to go through a very complex digestion and decomposition, and eventually become glucose, in order to be absorbed and used by the human body. It's unrealistic and hard to do that with a "desaccharged rice cooker" that wants to stop the body's blood sugar from rising by washing off starch. This will also lead to the loss of some water-soluble vitamins and other nutrients, not conducive to nutritional balance.
Gossip 5: Air fryers produce "carcinogens"
The truth is that air fryers work by "high-speed air circulation technology", which generates hot air through heat pipes in a high-temperature heating machine, and then blows hot air into the pot to heat food, allowing hot air to circulate in enclosed spaces. It uses the fat of the food itself to fry the food, dehydrated the food, the surface becomes golden crispy, to achieve the frying effect. It's actually a simple oven with a fan.
acrylamide is produced by "reducing sugars" (e.g. glucose, fructose, etc.) and certain amino acids (mainly celdonate) during frying, baking and baking. As long as there are carbohydrates and proteins in the food, acrylamide is inevitable during high heating. Compared with ordinary frying, the main feature of air fryer frying is "less oil" or "no oil", but this does not prevent the production of acrylamide. Therefore, acrylamide production can not blame the air fryer.
there is another view that the "thousand-roll oil" produced by air fryers produces carcinogens, and this fear is superfluous. Volatile fatty acids are found in all kinds of meat foods and have a strong aroma, so we think meat smells good. However, the vast majority of fatty acids are not volatile and do not evaporate with air into the air circulation of the air fryer. Volatile fatty acids account for a relatively small proportion of food, and studies have found that sheep, cattle and pigs account for 0.6g/kg, 0.45g/kg, and 0.2g/kg of total volatile fatty acids in adipose tissue, respectively. These volatile fatty acids evaporate quickly in the air and are not always present in the air fryer, so don't worry too much about their health.
Gossip 6: "Mobile Signal Enhancement Sticker" enhances signal reception range
Truth: "Mobile Signal Enhancement Sticker" is a plastic sheet coated with aluminum film, aluminum film also printed with a magnetic ink-like material. The merchant's claim that "the wavelength of the signal is enhanced by emenso-lengthing the wavelength of the signal received by the built-in antenna of the phone" does not make sense in principle.
first, wavelengths can't be "stretched" in real life; Moreover, each cell phone signal frequency is not the same, to achieve resonance must be the same as the corresponding cell phone signal frequency, a sticker even if it can produce some kind of resonance, it is not possible to meet all mobile phone frequencies.
Speed 7: security camera radiation, will affect fetal health
the truth: whether it is the "passing" security gate, or "passing" security screen, the radiation dose to the human body is very small, especially the security device, radiation dose is not as good as mobile phones. Generally speaking, the greater the power of the equipment, the greater the intensity of electromagnetic radiation. Mmwaw security device power is generally not more than 0.1 watts, and the maximum power of the mobile phone during the call can reach 2 watts. Security camera power is less than 1/20 of the power of the mobile phone, and ordinary people use the strength of the security device is much smaller than the mobile phone, through the security device when the distance is much greater than the contact distance with the mobile phone, so you do not have to worry about the electromagnetic radiation of the security device will affect health.
common X-ray security screen in life, its internal rays are all sealed in the machine, import and export using lead curtain, the internal four walls are also lead walls, under normal circumstances can effectively block X-rays into the external environment. During use, the machine emits rays only when the baggage item passes through the X-ray security machine. People just pass through it quickly, with very little radiation. Therefore, pregnant mothers can normally go through the security screening, do not worry about affecting their own and the health of the fetus.
8: "Non-fried" food is very healthy, can open to eat
truth: "non-fried" food is not necessarily healthy, the key depends on ingredients and technology. First of all, non-fried does not mean oil-free, many non-fried food added cooking oil is not a lot. Second, non-fried does not mean low fat, in instant noodles, fried and non-fried, the fat content can be more than double the difference, but for potato chips, non-fried and fried fat content is not much difference.
, non-fried does not mean low heating temperature, non-fried process if the temperature is high, long time, there is still nutritional damage. Therefore, you can't open up because it's "non-fried" food.
9: To avoid elevated cholesterol, eat more vegetarian
The truth is that human plasma cholesterol levels are not the same as cholesterol intake in three meals. First of all, the body has a set of adjustment mechanisms for cholesterol levels, cholesterol in the body usually comes from two channels, namely food digestion and absorption and biosynthetics in the body.
study found that even if a large amount of cholesterol is ingested from food, about 60% of plasma cholesterol still comes from biosynthesis in the body (the body synthesizes endo-cholesterol 1000 to 2000 mg per day, far higher than the intake of cholesterol in food), and some patients with high blood lipids do not consume cholesterol at all for a considerable period of time, plasma cholesterol levels can only be reduced by 10% to 25%. It can be seen that eating vegetarian food may also show elevated plasma cholesterol levels. Therefore, when plasma cholesterol concentration is too high, it is not enough to limit cholesterol intake alone. Eating cholesterol-containing foods at all can lead to nutritional deficiencies, which can easily lead to nutritional problems such as protein and essential fatty acid deficiencies.
Gossip 10: Eating bubble food can cause poisoning
Truth: the recent "acid soup" poisoning incident, so that rice enzyme acid in the public eye, many people worry about the safety of all kinds of soaked food. In fact, not all soaked food contains rice enzyme acid, may not have to refuse all soaked food, as long as the soaking time is reasonable, you can avoid poisoning, do not need to worry too much.
, a public dietitian at the Chinese People's Bank of China, said the following foods are likely to produce rice enzyme acid, which is crucial for proper immersion and consumption. Blackwood ears should not be soaked for more than 4 hours and the water temperature should not exceed 30 degrees Celsius. Experiments show that the edge of the black wood ear will crack after more than 6 hours, which not only seriously affects the quality of the wood ear, but also makes the wood ear more susceptible to microbial contamination.
and rice flour should not be soaked in hot water for more than 20 minutes, and boiled with boiling water for another 1 minute to 2 minutes before serving. If you use cold blisters directly, soak for 4 hours.
