Multi-organ insufficiency syndrome in the elderly is an important cause of death in elderly patients with critical illnesses. The impairment of body functions leads to a decline in body functions, and the body’s ability to resist infections decreases, and geriatric multi-organ insufficiency syndrome is a manifestation of a decline in infection resistance. What should I pay attention to in the daily dietary regimen for declining resistance to infection? 1, drink more yogurt: adhere to a balanced diet, if a person has alcoholism, mental tension or dietary imbalance, etc., it will make the person’s ability to resist disease weakened. To correct this imbalance, one must rely on nourishing bacteria, which are contained in yogurt. 2, drink more boiled water: plain water has a very desirable physiological activity on the human metabolism. Water is easily absorbed by the body through the cell membrane, so that the lactate dehydrogenase activity in the human organism is enhanced, thus effectively improving the body’s ability to resist disease and immunity. Especially the first cup of cool boiled water in the morning, especially important. 3, eat more seafood: seafood is rich in iron, zinc, magnesium, selenium, copper, etc., often eaten to promote immune function. 4, often drink tea: scientists have found that tea contains a chemical called theanine. Because it can mobilize the body’s immune cells to defend against bacteria, fungi and viruses, therefore, can make the body’s ability to resist infection increased by more than 5 times. 5, may wish to drink some red wine: most alcoholic beverages will play a suppressive role on the body’s immune system, but red wine is just the opposite, it contains some antioxidant substances to enhance immune function is very good, but also to help protect the heart. 6, eat some animal liver: animal liver contains folic acid, selenium, zinc, magnesium, iron, copper, as well as vitamin B6, B12, etc., these substances help promote immune function. 7, Cordyceps: can effectively increase the number of cells and tissues of the immune system, promote antibody production, increase the number of phagocytosis, killing cells, and can tone down the function of certain immune cells, is the first choice to enhance human immunity. 8, appropriate supplementation of iron: iron can enhance immunity; but excessive iron intake is harmful to the body, not more than 45 mg per day. 9, supplement glutamine: it is an essential non-essential amino acids, known as one of the “tools” to strengthen the immune system. For people who often have colds or diarrhea, glutamine powder can be added to juice or cold water. 10, supplement arginine: sea cucumber, eel, loach, cuttlefish, as well as yam, black sesame, ginkgo, tofu skin, frozen tofu, sunflower seeds, hazelnuts rich in this substance, eat more to help enhance immunity.
