Beijing, March 3 (Reporter Sun Zifa) The special program of the "Dian Zan 26 Science Popularization China" unveiling ceremony was broadcast on March 2022, announcing the top ten popular science figures, top ten popular science works, top ten popular science events and top ten scientific rumor lists in 3. Among them, 26 widely circulated rumors, such as vegetarian diets will not get fatty liver, type O blood and mosquitoes, were selected as the annual top ten scientific rumors that have attracted much attention.
The newly released list of the top ten scientific rumors in 2022 are:
Myth 1 – If you are vegetarian, you won't get fatty liver. People who are vegetarian for a long time, malnourished, and overweight may also get fatty liver. Apolipoprotein is required for fat metabolism as a "vehicle". When protein intake is insufficient, there is not enough apolipoprotein in the body and the liver cannot transport excess fat outward, and these fats accumulate in the liver leading to fatty liver.
Myth 2 – Injections after a child gets sick are "better faster" than taking medicine. Most oral drugs will go through the first elimination effect of the liver, the onset of action is relatively slow, and the risk of drug resistance and adverse reactions will be reduced. When injected drugs enter the human body directly, the risk of adverse reactions increases. Injection is usually chosen only when oral administration is not suitable.
Myth 3 – Antigen or nucleic acid tests will be positive after eating oranges. Eating oranges is difficult to influence the test results. If the antigen test is done correctly, the sampling site is the nasal mucosa, and there will be no contact with food here. The new coronavirus nucleic acid detection determines the results by amplifying the nucleic acid of the new coronavirus, which is eluted and purified in the process, and the impurities have little impact on the test results.
Myth 4 – Potatoes sprout, cut off the sprouts and eat. Dragon solanine is toxic, after the potato germinates, its solanine content will be greatly improved, a intake of 200mg solanine, that is, equivalent to about 30g of potatoes that have turned green or sprouted, can make people poisoned, severe and fatal. Potatoes that have sprouted severely or whose degree of germination cannot be judged should not be eaten.
Myth 5 - Type O blood attracts mosquitoes. Mosquitoes use their antennae to identify the smell emitted by the human body and select the target of their bite by smell. Human odor is mainly determined by genes, and this difference has nothing to do with blood type. People who recruit mosquitoes can generally use physical protection and chemical mosquito repellent.
Myth 6 – Honey and garlic can treat Helicobacter pylori infection. Online "sterilization artifacts" such as honey and garlic cannot treat Helicobacter pylori infection. Although bacteria will die in honey due to water loss, honey will be diluted when it enters the stomach and cannot achieve a sterilization effect. Although the allicin contained in garlic can inhibit the growth of bacteria, it will decompose after entering the human body, and it is difficult to exert bactericidal and antibacterial effects.
Myth 7 - After being infected with the new crown, you should use comprehensive medicine, so that it gets better quickly. This practice can be life-threatening. Each drug has a strict dosage, and taking a variety of drugs without authorization can easily cause repeated medication and overdose, endangering human health. For patients treated at home, it is recommended to follow the home treatment guidelines of the Health Commission, and do not combine drugs on their own.
Myth 8 – Myopia can be cured by surgery. Myopia is irreversible. The cause of myopia is a lengthening of the eye axis. At this stage, any means, including surgery and wearing glasses, can only correct vision, but cannot shorten the eye axis and restore its original shape, nor can it prevent complications caused by high myopia. Therefore, myopia prevention is more important.
Myth 9 – You can lose weight by eating only fruit. Eating only fruit is difficult to lose weight and unhealthy. To maintain health, you need a variety of nutrients such as protein, fat, carbohydrates, vitamins, and minerals. Eating only fruits for a long time will lead to malnutrition, and some fruits have higher sugar content, and excessive consumption of weight will even increase.
Myth 10 – Having a substation near your home is dangerous and you need to move. The alternating current frequency of China's substations is 50Hz, which is an extremely low frequency in the field of electromagnetic radiation, and the radiation range is very small, so residents do not need to worry. At the same time, the substation has a certain coverage area, that is, the power supply radius, beyond the power supply radius, it is impossible to ensure effective power supply, so the urban substation cannot be away from the residential area at will.
