Chinese American Medical Scientist Points Pigs to Gold
Because of obesity, Americans are paying more attention to the fat content and health of foods. When consumers are eating pork, even if they are aware of the high saturated fat and cholesterol in pork, they would like to avoid food, but they can't reach the temptation of pork foods that are readily visible in the menus such as barbecue, sausage, pork chop, and ham. They swallow them. However, due to the painstaking research of a Chinese-American medical scientist, pork is made more nutritious. In the near future, those pork crackers may be able to strengthen their cardiovascular health in the meantime. Dr. Kang Jingxuan is currently an associate professor at the Massachusetts General Hospital attached to Harvard Medical School and a research fellow at the Center for Cardiovascular Research. The results of a recent medical study he and his colleagues have shown indicate that genetic modification can "clon" pigs that produce large amounts of omega-3 fatty acids. Many medical reports show that this type of fatty acid, previously found only in fish, is beneficial to adults in preventing cardiovascular disease. Kang Jingxuan's research may bring healthier pork products to consumers and enable people to enjoy important nutrients for preventing heart disease while enjoying pork. “I have been doing this research project for many years. We successfully completed the same experiment on rats two years ago.†Kang Jingxuan said in the “Washington Watch†weekly magazine, “We have taken this step further in our application. Genetically modified, but not fed, pigs with omega-3 fatty acids are produced. In the future, we will continue to try to produce cows, chickens and other poultry with omega-3 fatty acids in the same way." Why choose "pig" home "cow"? Kang Jingxuan and his research partners’ scientific research results were published on the website of the monthly “Natural Biotechnology†in the United States on March 26th, 2006. The results were widely echoed, and the American mainstream media Associated Press and The New York Times both wrote in-depth articles. Kang Jingxuan also said in an exclusive interview with the weekly "Washington Watch" that he himself did not expect this study to arouse so much concern from all walks of life. “Dr. Kang’s research is very important. It can not only increase the nutritional value of American livestock, but also contribute to the nutritional value of poultry and livestock worldwide.†Alexander Leaf, Honorary Professor of Clinical Medicine, Harvard Medical School, for Washington Watch The weekly said, “The research of Dr. Kang is worth all the attention and interest of all parties.†Since the birth of Dolly, the world’s first cloned sheep, 10 years ago, more than 10 species of animals have been successfully cloned by humans. Breeding, including pigs, cattle, sheep, cats, horses and dogs, etc., but Kang Jingxuan et al's research is to change the nutritional value of animals through cloning technology, indeed the medical community's first move. “At the moment, this research has created a completely new era,†praised Alice Lichtenstein, a professor of nutrition science and policy at Tufts University in the United States. As a number of medical studies have reported that fat-rich fish, such as salmon, are rich in omega-3 fatty acids, it is an indispensable unsaturated fatty acid for human health, but the human body cannot naturally produce this fatty acid, and therefore must Instead, get it from other foods. In view of the fact that coronary heart disease and stroke are the largest and third largest disease killers in the United States, most of these diseases are caused by symptoms such as coronary arteriosclerosis and vascular thrombosis caused by excessive intake of saturated fat. Americans who eat high-calorie and high-cholesterol foods are encouraged to eat more fish. However, in the U.S. inland market, the high price of fish is not one of the staple foods of the Americans. The tuna (fish) that is rich in fish oil is also contaminated with mercury in the United States, which is expected by US consumers. Retired. "Not everyone can afford to eat more fish, which makes me very worried." Lifu said, "With Omega-3 cloned pigs, people can continue to eat their favorite junk food, and at the same time obtain Needs nutrition.†Rief's research on unsaturated fatty acids has helped human health for 16 years. He emphasized that this kind of fatty acid helps prevent inflammation and heart disease. It is very effective and people should try to take it as much as possible. The clone pigs containing omega-3 fatty acids introduced by Kang Jingxuan et al. may even have cloned and cloned chickens in the future, which may be able to solve the problem of people not being able to consume large amounts of unsaturated fatty acids in the near future. "Cloning pigs is only part of our pilot project. In the future we will invent cloning cows that also have omega-3 fatty acids, and we believe the impact will be even greater and more extensive," said Kang Jingxuan to the Washington Watch weekly. Americans averaged 51.8 pounds of pork per person in 2003, compared with chicken (82.5 pounds) and beef (64.9 pounds). Pork consumption cannot yet take the lead in the US meat consumer market. Kang Jingxuan further explained that the technology for cloning cattle and cloning pigs is almost the same, but it is easier to copy pigs, so the cloning pigs came out first. Genetically modified foods: difficult to market? “Although we can successfully replicate the livestock with high nutritional value, it is probably another matter for the products to reach the consumers,†says Kang Jingxuan. Kang Jingxuan's consideration is not without reason. U.S. genetically modified foods need to be inspected by the U.S. Food and Drug Administration (FDA) before they can be listed. In the United States, there are already many consumer groups and grassroots organizations advocating for animal protection, protesting U.S. farmers feeding their livestock with genetically modified grains. Therefore, if genetically modified poultry and livestock are directly placed on the meat market, it may cause a significant social rebound. “This is a double blow,†said Joseph Mendelson, legal director of the non-profit Food Safety Center in Washington. “I am confident that consumers will not want to eat them.†One of the initiatives of the Center for Food Safety is to oppose the listing of genetically modified foods. Liv said that the FDA's review period is long and the process is slow, so it will take a while for cloned pigs to go public through testing. He lamented that it is common for nature to change its genetic makeup, but when humans want to do so, they always cause attention and suspicion. Kang Jingxuan said that when his cloned pig can be listed, it is still unclear, and the main obstacle lies in when the FDA can pass the test. He can understand that there are many different reactions in the U.S. community to genetically modified pigs, but he believes that the listing of similar products is sooner or later. He disclosed to the Washington Watch weekly that after the results of his research were disclosed in the media, there were already two companies that were engaged in similar research - one in Canada and the other in Texas - and he was called to ask him about his research progress. As a result, it is clear that a large number of people are interested in such GM products. “My research finished products are not like other genetically modified livestock, but for the sake of producers, let these animals grow up and sell as soon as possible.†Kang Jingxuan said, “My genetically modified pigs are not purely beneficial to producers. Consumers also have great benefits.†Kang Jingxuan emphasized that based on this, his cloned pigs should be allowed to go public. The FDA has not yet approved GM animals as food shelves. Mandelson said the Center for Food Safety even questioned the FDA's ability to determine the safety of genetically modified foods. In addition, unhealthy animals may be created during the cloning process. Even those who do not oppose GM foods have a lot of questions. Lee Tengstan questioned how important Omega-3 fatty acids are to the human body. Is the same positive effect on human health as the Omega-3 fatty acids obtained from pigs? In view of this, Kang Jingxuan answered the "Washington Watch" weekly. “The omega-3 fatty acids produced in cloned pigs are identical to the omega-3 fatty acids obtained from fish. The chemical structure is exactly the same, but the amount of pigs in the pigs is relatively large,†explains Kang Jingxuan. Kang Jingxuan, born in Zhanjiang, Guangdong Province, graduated from the Guangdong Medical College in 1984 and was sent to study at the University of Alberta in Canada in 1987, specializing in biochemistry. After earning his doctoral degree in Canada in 1993, he came to the largest teaching hospital under Harvard Medical School--the Massachusetts General Hospital founded in 1811--participating in research and teaching work, and leading an American Academy of Medical Sciences.
