Bad for immunity: myths and reality

Chapter 1: Understanding immunity: Fundamentals and difficulties

Immunity is a complex system of protecting the body from foreign agents, such as bacteria, viruses, fungi, parasites and toxins. It consists of many interconnected components, including cells, tissues, organs and chemicals. The effective functioning of the immune system is a key factor in maintaining health and protecting against diseases.

1.1. Congenital and acquired immunity:

Immunity is divided into two main categories: congenital (non -specific) and acquired (adaptive).

Inborn immunity: This is the first line of protection presented from birth. It includes physical barriers (leather, mucous membranes), chemical barriers (gastric juice, lysozyme in saliva and tears), cellular components (macrophages, neutrophils, natural killers) and inflammatory processes. Congenital immunity reacts quickly and nonspecific to a wide range of threats. It does not have an immunological memory.
Acquired immunity: It develops throughout life in response to the influence of specific antigens (foreign substances). It is characterized by high specificity and immunological memory, which allows the body to respond faster and more efficiently with repeated meetings with the same antigen. The acquired immunity is divided into humoral (mediated antibodies) and cellular (mediated by T-lymphocytes).

1.2. Key components of the immune system:

Lymphocytes: The main cells of the acquired immunity. B-lymphocytes produce antibodies that neutralize antigens. T-lymphocytes are divided into several subtypes:
- T-highpers (CD4+): Coordinate the immune response, activating other immune cells.
- T-killer (CD8+): Destroy infected cells.
- T-regulatory cells (Treg): Sold the immune response, preventing autoimmune reactions.
Antibodies (immunoglobulins): Proteins produced by b lymphocytes in response to antigens. They are associated with antigens, neutralizing them or facilitating their destruction by other immune cells.
Macrophages: Phagocytes that absorb and digesting foreign substances and cell garbage. They also present antigens of T-lymphocytes, launching an adaptive immune response.
Neutrophils: The most common blood blood cells in the blood. They are the first cells arriving at the place of infection, where they phagocytes bacteria and other pathogens.
Natural killers (NK cells): Destroy infected and tumor cells without preliminary sensitization.
Dendritic cells: They present antigens of T-lymphocytes in the lymph nodes, playing a key role in activating an adaptive immune response.
Cytokines: Signal molecules regulating the interaction between immune cells and other body cells. Examples of cytokines: interleukins, interferons, tumor necrosis factors.
Compliment: A blood protein system that helps antibodies and phagocytes destroy pathogens.

1.3. Factors affecting immunity:

The functioning of the immune system is affected by many factors, including:

Age: The immune system is most effective at a young age. With age, immune aging occurs (immunosence), characterized by a decrease in the function of immune cells and an increase in the risk of infections.
Nutrition: Insufficient nutrition, especially the deficiency of vitamins and minerals, can weaken the immune system.
Stress: Chronic stress can suppress the immune function.
Dream: The lack of sleep can also weaken the immunity.
Physical activity: Moderate physical activity can improve the immune function, while excessive loads can suppress it.
Chronic diseases: Some chronic diseases, such as diabetes, cardiovascular diseases and autoimmune diseases, can weaken the immune system.
Medicines: Some drugs, such as corticosteroids and immunosuppressants, can suppress the immune function.
Vaccination: Vaccination helps the immune system to recognize and fight specific pathogens.
Genetics: Genetic factors can also affect the immune function.
Ecology: The impact of environmental pollution can weaken the immune system.

1.4. Immunodeficiency:

Immunodeficiences are conditions in which the immune system does not function properly, which makes a person more susceptible to infections. They can be congenital (primary) or acquired (secondary).

Primary immunodeficiency: Rare genetic diseases that affect various components of the immune system.
Secondary immunodeficiency: They develop as a result of other factors, such as HIV infection, chemotherapy, organs transplantation or insufficient nutrition.

Chapter 2: Dad for immunity: What is it?

Bades (biologically active additives) for immunity are products designed to maintain and strengthen the immune system. They contain various ingredients such as vitamins, minerals, plant extracts, probiotics and other substances that are supposed to have a positive effect on the immune function.

The composition of dietary supplements for immunity can vary significantly depending on the manufacturer and purpose. The most common ingredients include:

Vitamin C (ascorbic acid): A powerful antioxidant that plays an important role in the functioning of immune cells.
Vitamin D (cholegalciferol): Regulates the immune response and promotes the activation of immune cells.
Zinc: It is necessary for the development and functioning of immune cells.
Selenium: An antioxidant that supports the immune function.
SOUTINATEA: A plant extract, which is believed to stimulates the immune system.
Propolis: A bee product with antibacterial and antiviral properties.

Powders: You can add to drinks or food.
Chewing tablets and loafers: Convenient for children and people who have difficulty swallowing.
Tea drinks: Contain plant extracts and vitamins.

2.3. Legal regulation of dietary supplements:

Legal regulation of dietary supplements varies in different countries. In most countries, dietary supplements are not subjected to the same strict control as drugs. This means that manufacturers are not required to prove the efficiency and safety of their products before launching on the market. In Russia, dietary supplements are subject to state registration and must comply with the requirements of the technical regulations of the Customs Union.

2.4. Bades marketing for immunity:

The marketing of dietary supplements for immunity often uses the promises of strengthening the immune system, increasing resistance to infections and improving the overall health. However, it is important to remember that these promises are not always backed up by scientific evidence. Advertising of dietary supplements often appeals to the fear of getting sick and the desire to strengthen their health, which can encourage people to buy products that they do not need.

Chapter 3: Scientific data on the effectiveness of dietary supplements for immunity

Scientific data on the effectiveness of dietary supplements for immunity are ambiguous. Some studies show that certain dietary supplements can have a positive effect on the immune function, while other studies do not reveal any benefit or even indicate potential harm.

3.1. Vitamin C:

Vitamin C is a powerful antioxidant and plays an important role in the functioning of immune cells. Some studies show that the intake of vitamin C can reduce the duration and severity of colds, especially in people subject to intensive physical exertion. However, other studies do not reveal the significant effect of vitamin C on the prevention of colds.

3.2. Vitamin D:

Vitamin D regulates the immune response and promotes the activation of immune cells. Vitamin D deficiency is associated with an increased risk of infections, including respiratory infections. Studies show that vitamin D intake can reduce the risk of respiratory infections, especially in people with vitamin D deficiency. However, additional studies are needed to confirm these results.

3.3. Zinc:

Zinc is necessary for the development and functioning of immune cells. Zinc deficiency can weaken the immune system and increase susceptibility to infections. Studies show that zinc intake can reduce the duration and severity of colds, especially if you start taking within 24 hours after the appearance of the first symptoms. However, high doses of zinc can cause side effects, such as nausea and vomiting.

3.4. SOUTINATEA:

Echinacea is a plant extract, which is believed to stimulates the immune system. The results of the studies of Echinacea are contradictory. Some studies show that echinacea can reduce the duration and severity of colds, while other studies do not reveal any benefit. Additional studies are needed to evaluate the effectiveness of echinacea.

3.5. Probiotics:

Probiotics are living microorganisms that are useful for intestinal health and can affect the immune function. The intestines contain a large number of immune cells, and maintaining a healthy intestinal microflora can strengthen the immune system. Studies show that the intake of probiotics can reduce the risk of the development of respiratory infections and diarrhea, especially in children. However, additional studies are needed to determine the most effective strains of probiotics and optimal doses.

3.6. Selenium:

Selenium is an antioxidant that supports the immune function. Selena deficiency can weaken the immune system. Studies show that selenium intake can improve the immune function in people with selenium deficiency. However, too high doses of selenium can be toxic.

3.7. Other ingredients:

Scientific data on the effectiveness of other dietary supplements for immunity, such as propolis, garlic, beta-glucans, ginger root and curcumin, are limited. Additional studies are needed to assess their impact on the immune function.

3.8. Meta-analyzes and systematic reviews:

Met-analyzes and systematic reviews combine the results of several studies to obtain a more accurate assessment of the effectiveness of a certain intervention. Some metamin a-analyzes show that vitamin D intake can reduce the risk of respiratory infections, while other metaminations do not reveal the significant effect of vitamin C on the prevention of colds.

3.9. Research restrictions:

Many studies of dietary supplements for immunity have restrictions, such as small sample size, lack of control groups, biased methods for evaluating and financing research by dietary supplements. These restrictions make it difficult to assess the true effectiveness of dietary supplements for immunity.
