These foods have an indispensable effect on human immunity.
Studies have shown that high medical technology can reduce early death by 10% of patients, and a healthy lifestyle can reduce early death by 70% of patients without spending much money. So “the best doctor is himself, the best prescription is knowledge, the best medicine is time, the best mood is quiet.” Develop a good lifestyle, get healthy with a meal, and food is the best medicine.
Here are some common foods that are helpful for immunization. Have you ignored them?
Young rats that consume whey protein can increase the number of natural killer cells in the intestine, thereby enhancing intestinal immunity and reducing the risk of enterovirus infection.
Whey protein can enhance the recognition of antigen by the immune system and has a significant activation effect on adaptive immune response.
In addition to reducing allergic reactions, whey protein also inhibits the TH2 immune response, which is associated with an increased number of intestinal regulatory T cells.
Lentinus edodes mycelium promotes the secretion of IL-1β by phagocytic cells and then activates T cells to produce IL-2. Infected mice after oral administration of lentinan can increase the survival rate of infected mice and activate dendritic cells to secrete IL-12.
The mycelium polysaccharide and glycoprotein differentiation of Lentinus edodes promotes the production of IFN by mouse spleen cells.
In addition to the immunomodulatory active ingredient β-glucan, the mushroom is also rich in α-glucan extract, called active hexose related compound (AHCC), which can increase the survival rate of infected animals and increase serum. IgM and IgG production.
Soy peptide can increase the proportion of natural killer cells and macrophages in the blood, and can enhance the phagocytic activity, mainly to stimulate the activation of cellular immune response.
Soy isoflavones inhibit the production of inflammatory cytokines such as IL-6 and are regulated by the TLR receptor and NF-kB signaling pathways.
In the case of inflammation, supplementation with isoflavones can reduce the incidence of enteritis and rheumatoid arthritis; not only reduce IFN-γ, but also promote IL-4 production.
Soy isoflavones inhibit inflammatory responses and slow the development of low-type I immune-prone diseases. However, in animal experiments of ovariectomy, it was found that supplementation of soy isoflavones reduced the weight of the thymus, affected the maturation of T cells, and had a negative impact on the development of immune cells.
The polysaccharide component of Coix seed has the effect of inhibiting the excessive activation of complement and can slow the induction of inflammatory response.
Coix seed can reduce COX and NOS, thereby reducing the production of inflammatory factors such as PGE2 and nitric oxide.
Supplementation of coix seed can not only increase natural killer cells and Tc activity, but also increase IL-2 production and inhibit the allergen-specific IL-5.
Yam glycoprotein can activate natural killer cells and phagocytic cells, and it is confirmed that the TLR4 conduction pathway can promote the activation of macrophages to produce cytokines such as TNF.
Studies have shown that the use of propolis extract as an adjuvant not only promotes antibody production, but also increases IFN-γ, promotes T cell hormone secretion, and activates cellular immune responses.
In the case of high inflammation, cinnamic acid, coumaric acid, phenethyl caffeate and flavonoids in propolis can inhibit the occurrence of inflammation.
Propolis has a regulatory effect on type 1 and type 2 T cell responses.
It has been confirmed in the animal experimental mode that the plasma cells secreting immunoglobulin IgA in the intestinal tract of the sterile mouse are significantly less, and the formation of IgA in the mucosal tissue can be greatly enhanced in the state where the microorganisms coexist.
In addition to regulating the balance of intestinal microbes, long-term intake of probiotics can also enhance the body’s ability to secrete interferon-gamma, increase the production of intestinal IgA, produce antibacterial substances, and regulate the secretion of cytokines.
In prostatitis mice fed with probiotics, cytokines such as IFN-γ, IL-12, and tumor necrosis factor-α were significantly decreased in spleen and Pei’s lymphocytes, indicating that probiotics have an effect on intestinal inflammation.
In the mouse animal model, after treatment with Lactobacillus casei, probiotics promoted the production of IFN-γ and IL-5 in spleen cells and reduced the production of IgE.
The Dietary Guidelines for Chinese Residents (2016) pointed out that 250-400 g of cereal potato is ingested every day, including 50-150 g of whole grains and miscellaneous beans, and 50-100 g of potato. (Yam and Huanren are potato yam)
Eat a variety of dairy products, equivalent to 300g of liquid milk per day; soybeans and nuts 25-35g.
The sources of foods that regulate immunity are very extensive. Some of the ingredients listed in this article are summarized as follows: Microbial ingredients can mainly activate and regulate the immune system, anti-tumor, allergy and autoimmune diseases; plant and animal foods have anti-inflammatory , activate immune cells and alleviate allergies.
