Advertising is not credible, there is no cure for this disease, it can only be controlled! As a chronic disease, the treatment of diabetes is long and complicated. In addition, taking different treatment methods according to the patient's body and taking in trace elements, especially selenium, will bring great gospel to diabetic patients. The most important biological function of selenium is anti-oxidation, scavenging free radicals, and supplementing proper selenium is helpful to improve the insulin free radical defense system and the metabolic function of endocrine cells, which provides a new basis for preventing diabetic complications. In addition, selenium can also improve the blood viscosity of diabetes, delay the occurrence of diabetic complications and improve the prognosis of diabetes. Selenium is the active component of glutathione peroxidase, which can prevent the oxidative damage of islet β cells, make them function normally, promote sugar metabolism, and reduce blood sugar and urine sugar. Doctors can protect and restore the function of pancreatic islets by letting diabetic patients take selenium quantitatively, which is beneficial to improve the symptoms of diabetes and reduce the levels of glucose and hemoglobin in urine. In addition, selenium not only has insulin-like effect, but also has synergistic effect with insulin, which makes the role of selenium in the pathogenesis of diabetes more noticeable. So what do diabetics eat to supplement selenium in their daily diet? Foods rich in selenium include tartary buckwheat, konjac flour, eggs, peanuts, malt, liver, garlic, mushrooms and so on. Diabetic patients can choose reasonably according to their own situation. Moreover, natural ingredients have no toxic and side effects on the treatment of diabetic patients. Chromium is the only metal element in human body that will decrease with age, and it is a glucose tolerance factor. Chromium in diabetics will decrease, and chromium supplementation has a good effect on regulating blood sugar. There are trivalent chromium and hexavalent chromium, and trivalent chromium exists in human body. In 2000, the Nutrition Society of China determined that the suitable intake of chromium was 50ug/d and the maximum tolerable intake (UL) for adults was 500 ug/d.. What foods can be supplemented with chromium? Oysters, asparagus, mushrooms, onions, spinach, tomatoes, corn, peanuts, cocoa, chocolate, tea, canned food and acidic food cooked in stainless steel containers. Diabetes is a common, frequently-occurring and refractory disease in modern society. China's oldest traditional Chinese medicine literature, Huangdi Neijing, has related discussions. Neijing divides it into three stages: spleen carbuncle, thirst quenching and carbuncle eliminating, and systematically discusses the etiology, pathogenesis and prognosis of diabetes and its complications. Zhen Liyan of Sui Dynasty put forward in "Records of Ancient and Modern Times": "People who drink more water and urinate more, and are fat-free and sweet as bran tablets will quench their thirst." He knew that diabetes was much earlier than that of the Englishman Thomas William. Qian Jin Fang written by Sun Simiao, a drug king in the Tang Dynasty, and Wai Tai Secret Recipe written by Wang Dao, a famous doctor, contain a large number of prescriptions for treating diabetes and its complications. Fang pointed out: "The three cautious people, one is drinking, and the other is eating salty food and noodles"; "The Secret Recipe of Wai Tai" also pointed out: "This disease is especially taboo for atrium, hot noodles and dry breasts", all of which emphasized that the treatment of diabetes must be based on diet, and that "even if there is an elixir, it can't be saved!" Since then, doctors in past dynasties have accumulated a lot of experience in treating diabetes and its complications, and gradually formed a large number of medicinal diet prescriptions, some of which are still of great practical significance. Modern medicine also has many important expositions on the diet treatment of diabetes. Professor Lu Renhe, a famous expert on diabetes in contemporary Chinese medicine, put forward "258" for diabetes prevention and treatment, clearly putting diet therapy at the top of the three necessary basic treatment measures. With the development of society, modern nutrition has become an independent discipline, and the ingredients, functions and pharmacological effects of fruits, vegetables, grains, beverages and many traditional Chinese medicines have been preliminarily defined. All these have created conditions for the majority of diabetic patients to scientifically carry out diet therapy. Based on the above research results, People's Military Medical Publishing House and Zhu Han Cultural Communication (Beijing) Co., Ltd. organized experts to compile this book on dietotherapy for diabetes, which undoubtedly provided a useful reference for the daily diet health care of patients with diabetes and its complications. It is inevitable that there is something wrong with the article. I hope readers can have a reasonable diet, dialectical diet and scientific health preservation under the guidance of doctors according to their own specific conditions. 1.
