Protein
Protein is the basic cell of an organic material, is the main bearer of life activities, the immune system is composed of basic substances. The lack of protein has a great impact on immune function. Foods rich in protein include lean meat, fish, dairy products and soy products.
Aliphatic
fatty substance is a biological body energy storage, energy may be provided, maintenance of immune function. Excessive fat intake can cause arteriosclerosis, leading to cardiovascular and cerebrovascular diseases; insufficient fat intake can lead to metabolic disorders. The above two aspects will reduce immunity.
Vitamins
Vitamins are important to maintain human life activities of the active substance. The main role of vitamins is to regulate the body's metabolism. Appropriate intake of vitamins can enhance immunity.
Vitamin A maintains the function and structural integrity of epithelial tissues (skin, conjunctiva, cornea, etc.), promotes the synthesis of immunoglobulins, and participates in the body's oxidation process, especially the oxidation of unsaturated fatty acids. Foods that contain more vitamin A include animal liver, fruits, vegetables and so on.
B vitamins are a large family, mainly including vitamin B1, vitamin B2, vitamin B6, vitamin B12, folic acid and so on.
Vitamin B1 and vitamin B2 are involved in the metabolism of sugar, protein, fat and nerve cells in the body. Vitamin B1 is mainly found in rice bran, wheat bran, whole grains, beans and peanuts. Vitamin B2 is found in animal liver, eggs, dairy products and vegetables. Waiting for food.
Vitamin B6, vitamin B12 and folic acid are all involved in intestinal immune regulation.
Vitamin B6 also participates in the proliferation, differentiation, maturation and activation of lymphocytes, and participates in and regulates the inflammatory response. Vitamin B6 is found in foods such as yeast, grains, animal liver, eggs, and dairy products.
Vitamin B12 can be used as an immunomodulator of cellular immunity. Vitamin B12 exists in animal liver, fish, meat, eggs and other foods.
Folic acid plays an important role in the synthesis of protein and nucleic acid and the metabolism of various amino acids. It can participate in the synthesis of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Folic acid is abundant in yeast, green leafy vegetables, and animal liver.
Vitamin C can promote the synthesis of immunoglobulin, improve the function of white blood cells, promote the synthesis of interferon, and has an antiviral effect; it can promote the synthesis of collagen, which is beneficial to wound healing and strengthens the body's defense against foreign pathogens. For patients with pneumonia, vitamin supplementation can improve respiratory symptoms and shorten the length of hospital stay. Foods rich in vitamin C include fresh fruits and vegetables.
Vitamin D can maintain the body's calcium and phosphorus metabolic balance, promote bone growth, participate in the proliferation and differentiation of various immune cells, and regulate the body's immune function. Appropriate vitamin D supplementation can prevent acute respiratory infections. Vitamin D is found in deep-sea fish, egg yolks, dairy products, mushrooms, whole grains and other foods.
Vitamin E has many physiological functions such as anti-oxidation, maintaining fertility and regulating immunity. It can repair the defects of the immune system and eliminate infection. The vitamin E content in animal food is low, and the vitamin E content in wheat germ oil, sunflower oil, corn oil, palm oil, and spinach is rich.
Trace element
trace element content in the human body, though small, but the effect is very large. Lack of trace elements prevents metabolism in the body.
Zinc can enhance the vitality of T lymphocytes and enhance the sensitivity of nerves. Oysters are high in zinc in food. In addition, scallops, animal liver, cheese, mushrooms, and pecans are also important sources of zinc.
Selenium can resist cell oxidation and mutation, promote the inactivation of carcinogens in the body, and enhance the body's immunity. Foods that contain more selenium include pig kidney, sea cucumber, matsutake, oysters and so on.
Iron can promote the body's oxygen supply, enhance immunity, and inhibit the proliferation of cancer cells. Iron-rich foods include pork liver, seaweed, fungus, duck blood, lentils, sesame paste and so on.
Calcium and phosphorus can participate in the physiological activities of nerves and relieve fatigue. Foods rich in calcium and phosphorus include ribs, lean meat, dairy products, soy products, fresh vegetables, and seafood such as fish, shrimp, and crab
