As the Spring Festival approaches, people are paying more attention to health and food, giving the rumors a chance.Recently, a wave of rumors, under the name of academic research or authoritative organizations, have entered wechat moments: electric rice cookers are the “catalyst” for liver cancer, fast walkers live 15 to 20 years longer than slow walkers, Helicobacter pylori infection causes stomach cancer, and Grain shortage in China causes global food shortage.Today, Science Daily takes a look at the January rumors to help you clear the air and find the truth.Are rice cookers the Catalyst for liver cancer?Truth: Qualified products do not pose cancer risk “Who urges: Stop using rice cookers, which may be a cause of liver disease, but do not care” “Stop using rice cookers, which may be a ‘catalyst’ for liver cancer”…Recently, such rumors have put rice cookers on the hot topic list.Are rice cookers a health killer?Lu Gang, a professor at the School of Materials at Nanjing University of Technology, told Science and Technology Daily: “If teflon is made of qualified teflon, there is no cancer risk.”Lugang introduced that teflon has the characteristics of acid and alkali resistance, resistance to various organic solvents, almost insoluble in all solvents, even if placed in boiling aqua royal, will not happen any change.LuGang didn’t mince matters, however, made of the ptfe teflon have suspected cancer-causing substance, but the content is very low.”A surfactant called perfluorooctanoate is used in the synthesis of PTFE, which is a suspected carcinogen, but it is used in very small amounts and the product is rinsed with a lot of water before it leaves the factory, after which the amount of perfluorooctanoate is reduced to very little or no.”In addition, teflon is turned into Teflon by high-temperature treatment, in which pFOA is further removed, Mr. Lu said.Fast walkers live 15 to 20 years longer than slow walkers?”If you want to live longer, you have to walk faster!””You need to walk fast to live longer” “Fast walkers live 15 to 20 years longer than slow walkers”…Recently, a number of online articles have called for people to go under the name of “longevity”.The source of these sounds comes from a study published in the Mayo Clinic Proceedings.The study, conducted by researchers from Leites University and other institutions, involved 474,919 middle-aged and elderly people in the UK, with an average age of 58.2 years and an average body mass index (BMI) of 26.7.The study showed that those who walked faster had a longer life expectancy (86.7 to 87.8 years for women and 85.2 to 86.8 years for men);In contrast, those who walked at a slower pace had a shorter life expectancy (72.4 years for women and 64.8 years for men).The difference between the two is about 15 to 20 years, which has become the “basis” of the rumor.”The Internet myth that fast walkers live 15 to 20 years longer than slow walkers is exaggerated and the effect of walking speed on longevity has been magnified.”Xu Kai, an associate professor at the School of Sports and Health at Nanjing University of Sport and Science and Technology and chairman of the Jiangsu Science and Publicity Committee, told Science and Technology Daily that the research shows that walking speed is related to longevity, but that walking speed does not necessarily mean longevity.As the researchers state in their paper, observational studies cannot make inferences about cause and effect.”It’s the physical health of the person that matters.”According to Xu, there are many factors that affect physical health, including diet, mood and interpersonal relationships, and daily exercise is just one of them.Can infection helicobacter pylori get gastric cancer?Recently, a self-testing product of Helicobacter pylori came on the market and immediately caught fire on various e-commerce platforms.Behind this wave of agitation, more or less shows the public anxiety about Helicobacter pylori, this is not, “helicobacter pylori infection will get stomach cancer” rumors, and recently in the network popular, so the fact is really so?”Helicobacter pylori infection is a common infectious disease in China. Statistically, if you are infected with helicobacter pylori but are not treated in time, the risk of stomach cancer will be about 3 to 6 times higher than those who are not infected.”Zhu Hong, chief physician of the Gastroenterology Department of jiangsu Provincial People’s Hospital, told Science and Technology Daily, but he quickly changed his mind, “But even if you are infected with Helicobacter pylori, you don’t need to worry too much. Nationally, only less than 1% of people infected with HELICobacter pylori may develop stomach cancer.”Helicobacter pylori is the most common pathogen in the stomach.Zhu Hong said: “Helicobacter pylori infection may lead to inflammation of the stomach mucosa, which may lead to stomach cancer.In addition, because helicobacter pylori’s own gene products, bacterial proteins have certain carcinogenicity, which also determines the probability of people infected with helicobacter pylori suffering from gastric cancer is higher than that of uninfected people.He said the current infection rate of Helicobacter pylori in The Chinese population is around 40 percent, and the overall infection rate is declining with the country’s economic development and improved medical care.Can pylori helicobacter infection have a relapse after cure?Zhu Hong said that after helicobacter pylori is completely eradicated, the chance of real reinfection is very low, but if the eradication treatment fails, the titer of helicobacter pylori in the body is very low, the existing detection technology can not be measured, then after a period of time will be the old “disease” reignited.”Reinfection in adults after eradication therapy is associated with the home environment. If a family member is infected with H. pylori and everyone lives together, the risk of reinfection can be up to 5%.If a family member is not infected, the reinfection rate is only 4 percent.”Zhu Hong said.Is China hoarding causing Global food shortage?Recently, foreign media accused China of hoarding grain on a large scale and maliciously hyping grain prices, leading to famine in some countries.For Zhu Jing, dean of the School of Economics and Management at Nanjing Agricultural University and deputy director of the Jinshanbao Agricultural Modernization Research Institute, making China pay for the global food crisis is a publicity stunt.As we all know, With 9% of the world’s arable land and 6% of the world’s fresh water resources, China feeds nearly 20% of its population and has achieved a historic transformation from hunger to basic food and clothing to moderate prosperity.This not only ensures China’s own food security, but also makes a positive contribution to global food security.Zhu Jing analyzed that although China imports a certain amount of grain, it does not have first-hand sources of grain, but mainly buys second-hand sources from the four major international grain merchants.China does not have enough discourse power in the global food trade, nor does it control the food pricing power.The rise in global food prices since 2020 is mainly the result of a variety of factors, including the continuous spread of COVID-19, frequent occurrence of extreme weather, excess global liquidity and speculation by international capital.As a grain buyer, China’s procurement behavior is mainly based on the actual domestic demand and the supply situation in the international market, adopting standard international trade procurement behavior.Moreover, from the perspective of import structure, China’s grain imports are mainly soybeans, corn, sorghum, barley, etc., while imports of wheat and rice account for a relatively small proportion, which has little impact on global wheat and rice trade.”China has a large population, and its relatively sufficient inventory is the ‘ballast stone’ for food security, enabling China to cope with risks and challenges brought by various emergencies.””Too high a level of grain reserves is not the goal China is pursuing, which will not only bring financial pressure, but also lead to grain quality deterioration and loss,” Zhu said.In fact, instead of hoarding grain, China has been actively de-stocking grain in recent years.”This article is transferred from: Wenzhou news 66wz.com statement: reprint this article is for the purpose of passing more information.If the source is wrong or violated your legitimate rights and interests, please contact the author with proof of ownership, we will promptly correct, delete, thank you.Email address: newmedia@xxcb.cn
