Along with the popularity of social media such as Weibo and WeChat, there is a dazzling variety of health tips. From “How many glasses of water should I drink a day”, “When is the best time to sleep”, to “One hundred untold secrets of folklore”, “Beauty and beauty Bible “etc., as if all health-related worries, there are thoughtful solutions. However, in the eyes of experts, most of these nutrition advice of unknown origin lack scientific basis, blindly believe will cause health hazards. 1, health rumors flying around “Half Moon” magazine reporter noticed that often released health, beauty tips “@XiuXin health dictionary”, “@health a light official microblogging”, “@food health consultant “Most of these microblogs have millions of followers, and some popular posts have thousands of retweets and comments. Zhao Zhide, a junior at Weifang Medical College, was very surprised to notice the unreliable information on the Internet: “I didn’t expect that some clear and unquestionable pseudoscientific claims that have been refuted for years would still be widely spread. The public has a high degree of demand for life-like knowledge, but the ability to identify it is too poor.” For this reason, he used his spare time to compile the post “Those years, the dietary misconceptions we chased together”, which was widely reprinted on popular science websites such as Googles.com. “Eating collagen can be beautiful, tofu and small onion can’t be eaten together, and red dates and brown sugar are the most blood-supportive …… These widely circulated claims are actually quite unreliable.” In this post, he carefully refuted each and every one of the common dietary misconceptions. “I am just collecting and sorting out information based on professional knowledge. Many well-known doctors, have posted such disinformation before.” Zhao Zhide said, but rumors always rewind, baffling. 2. doctors who struggle with “unreliability” “Are these doctors or experts too serious? I think it is better to believe it than not to believe it.” For Ms. Liu, who often makes pig’s feet and soybean soup, eating more collagen-rich pig’s feet should be beauty. The actual fact is that there are some folk experiences spread on the internet, even if they are not scientific enough, there is no harm. However, in the eyes of doctors, some “unreliable” common sense health care, can cause adverse effects on people’s health. Who should I listen to when it comes to diet and health? Gu Zhongyi, a dietitian at Beijing Friendship Hospital and director of the Beijing Dietitians Association, said, “I have come across too much unreliable information, and some patients who come to the clinic have also listened to incorrect dietary guidance, resulting in hidden health problems.” When ordinary people say “anemia,” they think of “dates for blood. This is a misconception, Gu says. In fact, dates are no better than spinach and other vegetables for improving iron deficiency anemia, and much less effective than lean meat and other animal foods. Dates are rich in vitamins, but what people with anemia should be supplementing with is iron, and plant foods don’t contain much of it. Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety at the School of Food of China Agricultural University and a director of the Chinese Nutrition Society, believes that some of the claims of “food compatibility” are also typical of the misconceptions spread on the Internet. “I explained hundreds of times, the so-called food-phase argument is not based on the most difficult to extinct false rumors.” 3, the pursuit of health can not “listen to the wind is rain” in the new social media fast-paced, shallow reading influence, people see the post, often do not carefully identify, and even spread without thinking. Experts believe that in the age of self-media, where everyone can act as an “expert”, if you don’t have professional knowledge and discernment skills, you should not spread it freely. (1) It is best not to believe in “nutritional knowledge” that is not clearly attributed to the source. Fan Zhihong believes that each person’s physique is different, so the dietary taboos are also very different. So those who sound absolute, uniform statements are usually not scientific. Instead of blindly believing in crazy rumors, it is better to carefully read the relevant books, or the Dietary Guidelines for Chinese Residents issued by the Health and Welfare Commission. (2) Whether the information source is authoritative or not is most important. Some people let down their guard when they see some famous VVs forwarding it. In fact, the most important thing is whether the original information source is authoritative, not whether the intermediate “second hand” is reliable. (3) The right knowledge to identify unreliable paragraphs. “Ordinary people are concerned about their health, but lack judgment. This is the reason why some information that seems to be very serious but is actually very unreliable is widely spread.” Bi Lei, the head of Chunyu Pocket Doctor, which specializes in health communication, suggested that the public can seek confirmation of questionable posts from doctors’ personal microblogs, social networking platforms run by some professional organizations or professional science websites. Experts believe that when people learn to make judgments through common sense and logic, constantly seek evidence, question and selectively accept information, they will eventually find that the best doctor may be themselves.
