Immunity is the body's own defense mechanism, the ability of the human body to recognize and eliminate any foreign intruders (viruses, bacteria, etc.); to handle aging, damaged, dead, and denatured self-cells, as well as to recognize and process mutated cells and virus-infected cells within the body. Here are several foods that can boost immunity.
Eat more protein
Protein is the material basis for the body's immune defense function. In daily life, you should appropriately eat more foods rich in protein, such as lean meat, dairy products, fish and shellfish, and legumes.
Drink tea
American scientists announced a quantitative finding: a chemical substance called "theanine" in tea can enhance the body's ability to resist infection by 5 times. Theanine can also mobilize the body's immune cells to defend against viruses, bacteria, and fungi.
Supplement with vitamins
Vitamin C can inhibit the synthesis of carcinogenic nitrosamines in the diet and promote antibody formation, enhancing the phagocytic action of white blood cells, thereby strengthening the body's resistance. You can eat more fruits and vegetables rich in vitamin C, such as strawberries, tomatoes, cucumbers, and carrots. Vitamin A has a protective effect on the respiratory and gastrointestinal mucosa. A lack of vitamin A can reduce the body's antibody response, leading to a decline in immune function, allowing bacteria, viruses, and other pathogens to take advantage. Supplementing with vitamin A from food is a safe and effective health method. Eating more carrots can boost immunity, and the proper way to eat carrots is to stir-fry or stew them with a sufficient amount of oil.
Eat some animal liver
Canadian nutritionists believe that animal liver is rich in various substances that help promote immune function, such as folic acid, selenium, zinc, magnesium, iron, copper, and vitamins B6 and B12. Wheat bran contains magnesium, zinc, and selenium that can enhance immune function, and can be mixed into grain foods. Seafood also contains minerals such as iron, zinc, magnesium, selenium, and copper that help promote immune function.
Drink more water
Dehydration can weaken resistance. Drinking more water can make a person feel more energetic and can keep the mucous membranes in the mouth and nose moist, thus effectively enabling them to function in capturing bacteria and viruses.
Iron
Iron can also boost immunity. The Dietitians of Canada指出 that, generally speaking, women of childbearing age are more likely to be deficient in iron, but the maximum daily intake should not exceed 45 milligrams.
