Rumor 1 Food additives are all “technical and hard work”, and food with additives cannot be eaten.
Recently, the topic of “Hex Technology” (a science and technology fused with magic in the game) has been particularly hot on the Internet. The UP owners of some platforms have “revealed” the suspected illegal use of additives in certain foods in videos. Some people even claim that the use of additives in food is not safe.
Interpretation of the truth:
The use of additives in food does not mean it is unsafe, and food with zero additives does not mean healthier.
The so-called food additives, according to the definition of the “Food Safety Law of the People’s Republic of China”, are chemically synthesized or natural substances added to food for the purpose of improving food quality, color, aroma, and taste, as well as for the needs of antisepsis and processing technology. It can be seen that the birth of food additives is due to the rapid development of the food industry and is to meet people’s higher-level needs for food.
Some people think that the use of food additives is superfluous, and maintaining the original taste and shape of food is enough. Is that true? of course not. For example, the proper use of food additives such as colorants, color protectants, bleaching agents, emulsifiers, thickeners, and flavorings can improve the sensory properties of food. Some green vegetables will turn black in appearance during high-temperature processing and affect appetite. If the color-protecting agent is used properly at this time, the situation will be greatly improved, and the original color can still be maintained after various processing. Some color. As another example, the proper addition of certain food nutrition fortifiers belonging to the scope of natural nutrition can greatly improve the nutritional value of food. Among them, salt iodization is the most common example. This is of great significance to prevent people from malnutrition and nutritional deficiency, promote nutritional balance, and improve the health level of the human body. More importantly, the use of food additives such as preservatives and preservatives not only prolongs the shelf life of food, but also prevents food poisoning caused by microbial contamination. Some people may think that food should not be preserved for such a long time, otherwise the nutrients will be lost, which is very unhealthy. In fact, it is precisely these measures of preservation and antisepsis that allow us to have more abundant food resources, not only allow everyone to eat delicacies from all over the world, but also objectively solve the problem of food supply and reduce the risk of food corruption. waste.
Not all foods that claim to be additive-free are safe. If some food does not add preservatives, it will not be able to inhibit the reproduction of microorganisms, which will easily lead to deterioration. Another example is that infants who have just been fed complementary foods are prone to anemia, and it is very necessary to feed iron-fortified rice noodles at this time.
Although additives are not scourges, they must be used in accordance with the law. Food additives can’t be used as you want, and the public’s fear of it also stems from the occurrence of certain illegal activities. The “Sudan Red”, “melamine” and “Clenbuterol” that people have heard in recent years are not legally recognized additives, but illegal additives. my country adopts a strict approval management system for the use of food additives. Only food additives that are considered safe and reliable in terms of technology and technology will be approved for use after a risk assessment. Any over-range, over-dose and type of use is illegal and will be punished by law.
Advocating the consumption of more natural foods does not mean that foods containing additives should not be eaten. According to the dietary pattern recommended by the “Dietary Guidelines for Chinese Residents”, the key is to properly match various foods, have a balanced diet, and eat more nutritious and healthy.
Rumor 2 The 2022 Nobel Prize in Physics recognizes the feasibility of quantum entanglement, which means that quantum concept products are also feasible.
Interpretation of the truth:
The “quantum concept products” described on the Internet are basically related to health preservation, prevention and treatment of diseases, and have many “amazing” effects, such as improving various diseases of the body, opening up internal circulation, and superimposing “quantum energy” for the human body ,and many more. In fact, these claims are all deceptive.
Although after more than a hundred years of development, the related research of quantum science itself has formed a huge and flourishing system. However, it has to be admitted that many laws of quantum science are completely different from our daily experience in the macroscopic world. For example, in the macro field, for a watermelon, we can observe its shape and measure its weight. In terms of mass, it is generally calculated in kilograms, which can be any continuous value from 1 kilogram to several kilograms. But in the microscopic world, it is completely different. Its size does not change continuously, but is equivalent to an integer multiple of a certain “basic watermelon”, and there is no “microscopic watermelon” of other sizes.
The content of quantum science is actually the way of cognition of the world. At present, it is mainly used in the fields of quantum communication, quantum computing and quantum precision measurement. The corresponding technology has very strict requirements on the experimental environment, and the economic cost is particularly high. It is currently difficult to popularize and apply. in the civilian field. Those products under the guise of “quantum” are just new tricks of some unscrupulous merchants to “cut leeks”. Don’t be fooled by winning the Nobel Prize for quantum entanglement.
Rumor 3 Sleeping on a pillow can really be “worry free”.
The idiom “sleeping without worries” comes from “Warring States Policy · Wei Policy 1”: “If Qin is involved, Chu and Han will not dare to move. If there is no trouble between Chu and Han, then the king will sleep on his back, and the country will have no worries.” Its original meaning It is a booster pillow for a carefree sleep. In life, many people have the habit of using high pillows when sleeping, thinking that this is not only good for sleep, but also good for health. is this real?
Interpretation of the truth:
not necessarily.
In our daily cognition, a pillow is a bedding that is placed under the head when lying down to make the head slightly higher. In fact, pillows are not just used for pillows, their purpose is to keep the head at an appropriate height, keep the neck in a normal neck position, release the pressure on the neck muscles, and allow them to relax and rest. From this point of view, if the position and height of the pillow are not suitable, it will cause soreness in the neck, cause muscle strain, and even make it difficult to fall asleep in severe cases.
At the same time, not using a pillow is not a good sleeping habit either. Studies have shown that pillows that are too high or too low can cause harm to the human body. A pillow that is too high will hinder the normal blood circulation of the head, easily lead to cerebral hypoxia, and cause problems such as snoring and stiff neck. Especially patients with high blood pressure, cervical spondylosis and spondylosis should not use high pillows. A pillow that is too low can easily cause eyelid and face edema, and people with asthma, lung disease and heart disease should not use low pillows.
The scientific and comfortable pillow height is determined according to the physiological curve of the human cervical spine. Only by maintaining its normal physiological curvature can the joints, muscles and ligaments of the shoulder and neck be in a relaxed state and get a better rest. Under normal circumstances, the height of the pillow should be slightly lower than the distance from the shoulder to the neck on the same side.
Of course, different sleeping positions have different requirements for the height of the pillow. For people who are accustomed to sleeping on their backs, the height of the pillow is preferably 8 to 13 cm. Also, place a pillow under your knees to relieve pressure on your spine. For people who are accustomed to sleeping on their side, the height of the pillow should be the width of the individual’s shoulders, about 13 to 15 centimeters, so that the cervical spine and lumbar spine are almost on the same level. In addition, people who like to sleep on their stomachs can choose very thin and light pillows. However, it is not recommended that you sleep in a prone position for a long time, because doing so will easily cause pressure on the heart and is not conducive to breathing.
The lumbar spine and cervical spine of children and adolescents are still in the stage of further development. Long-term use of pillows that are too high or too low will affect the physiological curvature of the spine. It is recommended to choose an appropriate height.
