Can Sleep And Eating Boost Immunity?
Dec 14, 2022
Before the development of effective vaccines and drugs, immunity has become the only "weapon" for the prevention and treatment of new coronary pneumonia. The basis of immunity is all kinds of nutrients and energy. Previously, "Life Times" used "Protein, the Key Anti-Virus Nutrient" as the theme, emphasizing that protein is an essential "raw material" for immunity. Recently, Japanese medical expert Yanagisawa Kosei (referred to as "Yanagizawa") wrote an article saying that taking enough vitamin C, vitamin D, zinc, Cistanche Phenelythenal Glycoside ,selenium, magnesium and sulforaphane from food can improve the body's immunity. Effective against the new crown virus. When our reporter interviewed authoritative experts, they said that on the basis of the above, several nutrients should be added to improve immunity.

Sufficient nutrition is the best medicine to enhance immunity
Recently, researchers from China, Britain, the United States and other countries used the analysis of the 2017 Global Burden of Disease Report and the United Nations population estimates to find that about 1.7 billion people in the world have at least one underlying disease. Once these people are infected with the new coronavirus, they will develop severe new coronavirus The risk of pneumonia is greatly increased. And the risk increases with age. According to estimates, there are about 349 million potentially high-risk patients with severe new crowns in the world. In other words, these people must be hospitalized once they are infected with the new crown. The study pointed out that in countries with relatively serious aging, African countries with high prevalence of AIDS, and some countries with high prevalence of diabetes, the risk of severe new coronary pneumonia is the highest.
Pan Pinghua, an expert in the medical treatment team of the State Council's joint prevention and control mechanism for COVID-19 and director of the Department of Respiratory and Critical Care Medicine, Xiangya Hospital of Central South University, said that this study shows that for people in areas with insufficient nutrition such as Africa, it is necessary to strengthen nutrition and improve immunity. It is one of the important measures to prevent and control the new crown. It has also been found in clinical treatment that young people have a high proportion of mild symptoms after infection, while elderly patients, especially those with chronic underlying diseases, are relatively more prone to disease due to low immunity, and more severe cases. In terms of antibody production, middle-aged and elderly people with relatively low immunity produce antibodies for a long time or in small quantities, and some even do not produce antibodies. In terms of recovery, young people with strong resistance recover quickly, and most of them have a better prognosis; many middle-aged and elderly people have a poor prognosis. "The most important task of doctors in treatment is to help patients adjust their immunity so that they can withstand the virus." Pan Pinhua said.
Yanagisawa pointed out in his article that if the immunity is improved, even if infected with the new coronavirus, it will be a mild disease; if the cytokine storm can be suppressed, even if it develops into a severe disease, the possibility of survival will increase. "Eating well and sleeping well is the best medicine to enhance immunity." Pan Pinhua said that during his treatment in Wuhan, he found that patients with adequate and comprehensive nutritional intake would recover better and have a lower mortality rate. It is generally believed that in addition to the decline of immune function due to aging, malnutrition, pathogen infection, use of immunosuppressants, liver cirrhosis, diabetes, malignant tumors and blood system diseases will all affect the immune system function. In addition, irregular work and rest, unbalanced diet, and low mood can also make the immune system unbalanced. The significance of nutritional support to immunity lies in that, under the exclusion of other influencing factors, only when all kinds of nutrition are fully balanced can the immune system be fully functional and the body's own ability to resist viruses can be exerted. As early as February 12, Zhao Wenhua, a researcher at the Institute of Nutrition and Health of the Chinese Center for Disease Control and Prevention, mentioned that nutrients are an important means of preventing, treating and recovering from diseases for health.
11 Nutrients That Affect Immunity
Regarding the six important nutrients recommended by Liu Ze, Zuo Xiaoxia, director of the Nutrition Department of the Eighth Medical Center of the PLA General Hospital, gave a detailed interpretation.
Vitamin C: Prevents viral respiratory infections and reduces symptoms. A researcher conducted a vitamin C intervention test on cold symptoms of students who had been exercising for 10 days. The results showed that students who took vitamin C had an 85 percent reduction in colds and flu. Zuo Xiaoxia said that vitamin C corrects immune system disorders by affecting the proliferation and differentiation of various immune cells, the secretion of cytokines, and anti-oxidation. It can not only reduce the interference of the outside world on the balance of cells, but also promote the formation of antibodies and maintain normal immunity.
Vitamin D: reduces the risk of death in people infected with the new crown. A study in Indonesia showed that 90% of the patients who were hospitalized with the new coronavirus but survived had normal blood vitamin D levels; more than 90% of the patients who died were deficient in vitamin D. Zuo Xiaoxia said that vitamin D is a "necessity" for the immune system. It can regulate cell proliferation and differentiation, and is closely related to the functions of the immune system and nervous system.
Zinc: Inhibits the proliferation of coronaviruses. Studies have found that zinc can inhibit the synthesis of SARS virus protein and RNA (a viral genetic information carrier), thereby inhibiting virus proliferation. Since the new coronavirus is the same coronavirus as the SARS virus, zinc may have the same effect on the new coronavirus. Zinc is an activating factor or cofactor of more than 300 kinds of enzymes and active proteins in the body, and plays a non-negligible role in the development of the immune system and the maintenance of normal immune functions. Zinc deficiency can easily cause low immunity, loss of appetite, and susceptibility to infectious diseases.
Magnesium: involved in the formation of antibodies. Magnesium participates in the synthesis of proteins, fats, DNA, and RNA in all cells, involving the activities of more than 300 enzymes, affecting all aspects of life. Magnesium deficiency will reduce the body's protein synthesis ability and affect immunoglobulin, thereby affecting the body's immune function and disease resistance.
Selenium: Accelerates recovery from COVID-19. A study published in the American Journal of Clinical Nutrition found that a diet high in selenium can help speed up recovery from COVID-19. Selenium is an essential trace element for maintaining the immune system and anti-infection ability. It can stimulate the production of immunoglobulin and increase its content. At the same time, it can also significantly increase serum antibody levels and antibody responses. On the contrary, selenium deficiency can induce impairment of cellular and humoral immune mechanisms, thereby reducing resistance to infection.
Sulforaphane: Activates and strengthens immunity. Experts from the National Academy of Sciences of the United States found that glucoraphanin can activate the "longevity switch" Nrf2 signaling pathway by converting it into sulforaphane in the body. Nrf2 can play a role in cytoprotection and innate immune regulation, that is, glucoraphanin can indirectly strengthen immunity. Animal experiments have proved that sulforaphane has an antiviral effect, can strongly inhibit the main inducer of inflammation, and can also relieve lung inflammation caused by acute respiratory distress syndrome.
Vitamin A: participates in the whole process of human immune system maturation. Vitamin A helps maintain the integrity of the skin and mucous membranes. When vitamin A is sufficient, the skin and the protective layer of the body (such as the gastrointestinal tract, respiratory tract, and reproductive tract epithelium) can maintain normal anti-infection capabilities. In addition, vitamin A also improves immune function by regulating cellular and humoral immunity.
Vitamin E: Improve the body's cellular and humoral immune functions. Vitamin E maintains its integrity and stability by protecting cell membranes and organelle membranes from oxidative damage to ensure normal cell function. Studies have shown that vitamin E can promote the development of immune organs and the differentiation of immune cells within a certain dosage range, and improve the body's cellular immunity and humoral immunity.
Cistanche: Cistanche Extract is a standardized highly potent 100 % Natural Cistanche extract from which is standardized to a minimum 15-85% Phg and 5-40% Echinacoside and 1-16% Acetoside (Verbascoside) in Herbal Cistanche. It is also important to note that many other Cistanche supplements on the market do not test or standardize to these bioactive compounds that make Cistanche such a potent and highly sought after supplement.
Modern Clinical Show: Echinacosides in this plant extract encourage healthy nervous system function for longer stamina and optimal immune senescence protection. Acteoside one of the glycosides is considered to be a very strong antioxidant. Its antioxidative properties are 15 times greater than that of polyphenols found in grapes and more than five times higher than that of vitamin C found in oranges and pepper.
Iron: Necessary for antibody production. Iron constitutes hemoglobin, myoglobin, cytochrome and certain respiratory enzyme components, participates in oxygen transport in the body and tissue respiration, and maintains normal hematopoietic function. Iron deficiency can lead to a decrease in the number of immune cells, which in turn affects antibody production and leads to a defective immune response.
Protein: the material basis of anti-virus. Protein is the material basis of the body's immune defense function, and is the raw material for the synthesis of various enzymes, hormones, antibodies, and immune factors in the body. These substances help to speed up chemical reactions in the body and regulate body functions. Insufficient intake will affect tissue repair, reduce the local immunity of the skin and mucous membranes, easily cause the proliferation and spread of pathogenic bacteria, and reduce the ability to resist infection.
Omega 3 polyunsaturated fatty acids: can reduce inflammatory storms. Dr. Lin Shaohui from Xiangya School of Medicine, Central South University once wrote that omega 3 polyunsaturated fatty acids can effectively reduce the incidence of "inflammatory storm". Clinical studies in many hospitals have shown that appropriately increasing the intake of this nutrient in patients with severe new coronary pneumonia can regulate the balance of lipid metabolism and delay the progress of systemic inflammatory response to a certain extent.
Reasonable supplements can enhance immunity
During the epidemic, it is very necessary to ensure adequate nutrition. When you cannot detect whether your own nutrients are adequate and balanced, the best way is to supplement nutrients from daily food.
Foods rich in high-quality protein mainly include fish and shrimp, poultry, eggs, lean meat, milk, soybeans and their products. Foods rich in vitamin A include animal liver, cod liver oil, fish eggs, whole milk, poultry eggs, etc. β-carotene provided by orange and dark green fruits and vegetables (carrots, pumpkins, broccoli, amaranth, spinach, etc.) Converted to vitamin A in the body. Vitamin C is mainly found in fresh fruits and vegetables, such as sweet peppers, bitter gourd, cauliflower, broccoli and mustard greens in vegetables, and fresh dates, kiwi fruit, cherries, pomegranates, oranges, lemons, grapefruits and strawberries in fruits. Vitamin D sources include cod liver oil, liver, kidney, whole milk, butter, egg yolk, fatty fish, etc. Foods rich in vitamin E mainly include nuts, such as melon seeds, sunflower seeds, walnuts, almonds, vegetable oil, wheat germ, barley, brown rice, etc. Zinc-rich foods are mainly protein-rich foods, such as shellfish, shrimp and crab, offal, meat, fish and so on. Crustaceans such as snails, oysters, and mussels are rich in zinc. Among the seeds, sesame, sunflower seeds, and pine nuts are also high in zinc. Magnesium-rich foods are mainly dark green vegetables, especially spinach, which is high in content. Foods rich in sulforaphane include cruciferous vegetables such as broccoli and kale. The selenium content in food is greatly affected by the place of origin, and the selenium content in cereals varies from region to region. Generally, seafood, liver, kidney, and meat are rich in selenium content. Iron supplementation mainly relies on heme iron in animal foods, and the important source is the "iron triangle", that is, red meat, animal blood and liver. Omega 3 polyunsaturated fatty acids are mainly derived from deep-sea fish, flaxseed, perilla seed, seaweed, etc.
During the epidemic, to ensure sufficient nutrition, it is best to eat no less than 12 kinds of ingredients every day, with rich and diverse colors, no partiality, no picky eaters, and a combination of meat and vegetables. If it is true that some foods are temporarily in short supply, leading to an unbalanced diet, you can take nutritional supplements in moderation.
