How to make diet our immune booster?

January 05, 2024

Reasonable nutrition is an important condition for maintaining normal immune function. Malnutrition can lead to underdeveloped immune organs, decreased immune functions such as cellular and humoral immunity.

01 Energy and Protein

Excessive or insufficient energy intake can affect the body's immune function. Proteins and amino acids constitute the basic substances of the immune system, such as proteins, which are components of immune factors such as cells and antibodies. Their deficiency has the greatest impact on immune function.

02 Fatty acids

Excessive intake of dietary fat, improper ratio of saturated and unsaturated fatty acids, as well as n-3 and n6 in unsaturated fatty acids, can all lead to a decrease in immunity.

03 Vitamins

1. Vitamin A and carotenoids

Epidemiological investigation shows that vitamin A nutrition is an important factor influencing the incidence rate of respiratory infection and diarrhea in children. Carotenoids are precursors of vitamin A and also have immunomodulatory effects.
It should be emphasized that excessive vitamin A can also cause poisoning.

2. Vitamin E

The main physiological function is antioxidant effect, and its impact on immunity may be by reducing the formation of free radicals, maintaining immune cell function from damage; It can also regulate immune responses.
Within an appropriate range, vitamin E can promote the development of immune organs and enhance immunity. Similarly, excessive vitamin E can also cause poisoning, and deficiency or excess can lower immunity.

3. Vitamin C

Vitamin C can promote the synthesis of immunoglobulin/lymphoblasts, enhance white blood cell function, and promote the synthesis of interferon, thus having antiviral effects. In addition, vitamin C can also promote collagen synthesis, enhancing the body's resistance against foreign pathogens.

4. Vitamin B

Lack of B vitamins such as pantothenic acid, riboflavin, and folic acid can cause a decrease in cellular and humoral immune functions.

04 Trace elements

Lack of trace elements can directly cause damage and differentiation of immune organs and cells in the body, and indirectly lead to a decline in immune function by affecting the nutritional metabolism and growth and development of other tissues.

Most trace elements such as zinc, iron, selenium, etc. have important effects on the immune function of the body, and there are synergistic and/or antagonistic effects among these elements. The deficiency or excess of trace elements can affect the immune function of the human body.

In order to ensure the proper amount and proportion of nutrients, experts and scholars such as the National Health Commission, the Chinese Nutrition Society, and the Society of Parenteral and Enteral Nutrition of the Chinese Medical Association have formulated nutritional diet guidance for the prevention and treatment of pneumonia caused by COVID-19:

Emphasize moderate energy:

Supplementing with sufficient high-quality protein and consuming various types of milk and dairy products; There are vegetables and fruits in the meal, often eat soy products, and eat nuts in moderation; Eat fish, poultry, eggs, and lean meat in moderation, and eat less fat, smoked, and pickled products; Reduce salt and oil, control sugar and limit alcohol; Eat less and balance, maintain a healthy weight, and other related content.
