Vitamins and minerals that help improve resistance and immunity include fat-soluble vitamins: vitamin A and vitamin E, minerals are iron, zinc, …
Use foods with natural antibiotics and preventive effects such as onions, garlic, lemongrass, apricot leaves, perilla, marjoram, basil, ginger, mint, herbs, basil, … Can be used 2-3 raw cloves of garlic during a meal or when preparing food to enhance resistance.
The role of some vitamins and minerals to enhance resistance and immunity
Also known as “anti-bacterial and viral vitamins” have a pronounced role both in humoral and cellular immunity. The role of vitamin A with the immune response is expressed in the role of vitamin A with the integrity of the epithelium. Lack of vitamin A epithelial hyperplasia, keratinization, excretory glands reduce excretion, ability to prevent the penetration of bacteria decreases. VitaminA is found in gac, spinach, rice, chicken liver, pig liver, beef liver, …
Vitamin E (tocopherols) boosts immunity by protecting cells from injury, thus increasing the body’s resistance to stronger bacterial infections, slowing the progression of dementia (Alzheimer’s) , protects vitamin A and fat of cell membranes from oxidation, participates in cellular metabolism. Vitamin E is found in foods of natural origin: soybean, bean sprouts, peanuts, barley sprouts, sunflower oil, olive oil and dark green leafy vegetables.
Immune boosting roles, they support the production of interferon, the protein made by the body’s cells to fight off pathogens, which are an important protein component of the immune system. Needed for immune cells T and white blood cells. Thereby increasing the function of the immune system …
Lack of vitamin C, susceptibility to infectious diseases increases, people infected, the vitamin C in the blood often decreases, lack of vitamin C increases capillary permeability, fragile vessels, dry skin. If you eat enough vitamin C, the immunoglobulins IgA and IgM increase, the activity of white blood cells increases, stimulates the transformation of lymphocytes and helps form the complement. Vitamin C helps increase the absorption of trace minerals (iron, zinc …) which are essential micronutrients for brain activity. More than 90% of the vitamin C in the diet comes from fruits and vegetables. Foods rich in vitamin C: vegetables, coriander, amaranth, jute, spinach, scallions, etc. in fruits such as grapefruit, enough, tangerines, oranges, lemons, …
Among the B vitamins, the role of folate and pyridoxine is more noticeable. Folate deficiency slows down the synthesis of cells involved in immune mechanisms. Similar to iron deficiency, humoral immunity is less affected than cell-mediated immunity. In fact, in children, especially pregnant women, folate deficiency is often accompanied by iron deficiency, which are two factors causing nutritional anemia. Deficiency of pyridoxine (vitamin B6) slows the immune function, both humoral and cellular mediators. B vitamins are found in rice bran, cereals, legumes, sesame, wheat germ, heart, liver.
The role of some minerals and immunity.
Many minerals and micronutrients are involved in the immune system, of which the role of iron and zinc is studied the most.
Iron deficiency, bacterial infection increased. Iron deficiency is often accompanied by a lack of protein – energy, so when supplementing iron for malnourished children, it is important to pay attention after 5 to 7 days of nutritional recovery, otherwise free iron will be a favorable factor. for developing bacteria. Iron affects cell-mediated immunity rather than humoral immunity. Iron is abundant in wood ear, mushrooms, red amaranth, soybeans
Zinc has a very important biological role as a selective effect on the synthesis and resolution of nucleic acids and proteins. Zinc boosts immunity, helps wounds heal and helps maintain taste and smell. Zinc is involved in hundreds of metabolic enzymes in the body, so when zinc deficiency children are susceptible to respiratory and digestive infections due to reduced resistance. When zinc deficiency children often appear anorexia retardation, growth retardation height. Rich foods such as meat, fish, shrimp, shellfish, milk, eggs, clams, oysters, ..
At the present time when the coronavirus epidemic with the number of people infected in 27 countries is increasing, increasing the vitamins and minerals in daily meals is very important in improving the body’s resistance, reducing risk of coronary virus disease and reduced mortality.
In addition, people also need to pay attention to improving the body by the addition of other forms of syrup, or other forms of multivitamin-mineral nuggets for children, or multivitamins – minerals for adults to help improve the health. resistant and immune, because in the composition of these products contain ingredients such as vitamins A, E, C, iron, zinc, …
Drink enough water as needed from 2.0-2.5 liters of water / person. Can use lemonade, orange juice, lemongrass, ginger juice … depending on the body of each person.
