However, there are not so many types of vitamin products. What effect does it have on our immunity?

Fat-soluble vitamins: essential for human immunity

1. Vitamin A

Vitamin a can promote the synthesis of immunoglobulin and improve the body's ability to fight infections and tumors. Vitamin a can also eliminate immune tolerance. Various cytokines that affect the immune response may also change in the absence of vitamin A, thereby affecting the body's antigen-antibody response.

Vitamin A is mostly found in animal foods, such as animal liver, fish eggs, whole milk, poultry eggs and so on. In addition to animal foods, carotenoids in plant foods can also be converted into vitamin A. They are mainly found in dark green or red-orange vegetables or fruits, such as broccoli, spinach, water spinach, mango, apricot, persimmon, etc. .

2. Vitamin D

Vitamin D is an important immunomodulator. Most research cells in the body, including cells of the immune system, contain vitamin D receptors. Vitamin D in macrophages can regulate the synthesis of endogenous cathepsin, and regulate the secretion of cell growth factors; analysis of cathepsin and cell function factors can enhance our body’s defense against pathogens . People in a vitamin D-deficient society are more likely to cause respiratory infections, their infection frequency is higher, and the risk of disease is more serious.

Human vitamin d is mainly obtained through exposure of the skin to ultraviolet radiation or from the diet. Vitamin d in food is mainly found in high-fat marine fish, animal liver, egg yolk and cream.

3. Vitamin E

Vitamin E is important for maintaining normal immune system function, especially for the function of T lymphoid tissue cells: it can enhance the responsiveness of lymphocytes to mitogen stimulation, antigen and antibody response, and promote phagocytosis; research results show that vitamin E It can further develop and affect autoimmune regulation functions by directly affecting nucleic acid and protein metabolism.

The main source of vitamin E in the daily diet is vegetable oil. In addition, barley, oats, rice bran and nuts are also good sources of vitamin E.
