Budget dietary supplements for immunity: economical protection

Section 1: Immunity: Fundamentals and importance

1.1 What is immunity?

Immunity is a complex biological system designed to protect the body from exposure to foreign agents, such as bacteria, viruses, fungi, parasites and toxins. It is a set of mechanisms that allow the body to recognize and neutralize these threats, supporting internal homeostasis and preventing the development of diseases.

The immune system is not a single organ, but rather a network of cells, tissues and organs working together. Key components include:

• White blood cells (white blood cells): The main cells of the immune system that recognize and destroy pathogens. There are various types of leukocytes, each of which plays its specific role, for example, lymphocytes (T cells, B cells, NK cells), neutrophils, macrophages and eosinophils.
• Lymphoid organs:
  • Bone marrow: The place of formation of most cells of the immune system.
  • Timus (thymus iron): The ripening place of T-lymphocytes.
  • Lymphatic nodes: They filter lymph containing foreign substances and cells, and initiate an immune response.
  • Spleen: He filters blood, removing old and damaged cells, and also participates in immune reactions.
  • Tonsils and adenoids: Protect the upper respiratory tract from infections.
• Antibodies (immunoglobulins): Proteins produced by b-lymphocytes, which are associated with antigens (foreign substances) and neutralize them or facilitate their destruction.
• Cytokines: Signal molecules used by the cells of the immune system to exchange information and coordination of actions.
• Complement: The blood protein system, which enhance immune reactions, destroy pathogens and contribute to inflammation.

1.2 types of immunity

Immunity can be divided into two main types:

• Inborn immunity: The first line of protection of the body, which acts immediately against a wide range of pathogens. It is nonspecific, that is, it does not distinguish specific pathogens, but reacts to common signs of threats. The components of congenital immunity include:
  • Physical barriers: Leather, mucous membranes, tears, saliva and gastric juice.
  • Cells of congenital immunity: Neutrophils, macrophages, NK cells (natural killers) and others.
  • Inflammation: The body’s protective reaction to damage or infection, characterized by redness, edema, heat and pain.
• Acquired (adaptive) immunity: It develops throughout life in response to the influence of specific pathogens. It is specific, that is, it recognizes and remembers specific antigens, and has immunological memory, which allows the body to respond faster and more efficiently to the re -effect of the same pathogen. The acquired immunity is divided into two main types:
  • Humoral immunity: Mediated by antibodies produced by b lymphocytes. Effective against extracellular pathogens, such as bacteria and viruses in blood and tissue fluids.
  • Cellular immunity: Mediated by T-lymphocytes (T-killer and T-Hellers). Effective against intracellular pathogens, such as viruses, bacteria and parasites that infected the cells of the body, as well as against cancer cells.

1.3 factors affecting immunity

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

• Age: The immunity is most strong in adulthood, but weakens in infants and the elderly.
• Nutrition: The lack of nutrients, such as vitamins, minerals and proteins, can weaken the immune system.
• Stress: Chronic stress suppresses the immune function.
• Dream: The lack of sleep reduces the activity of immune cells.
• Physical activity: Moderate physical activity strengthens the immune system, and excessive – can weaken it.
• Chronic diseases: Some diseases, such as diabetes, HIV/AIDS and autoimmune diseases, weaken the immune system.
• Medication: Some drugs, such as corticosteroids and immunosuppressants, suppress the immune function.
• Bad habits: Smoking and alcohol abuse weaken the immune system.
• Environmental factors: Environmental pollution can negatively affect immunity.
• Genetics: Genetic factors also play a role in determining the strength of the immune system.

1.4 Signs of weakened immunity

Weakened immunity can be manifested by various symptoms, including:

• Frequent colds and infections: More frequent episodes of colds, flu, sinusitis, bronchitis and other infections than usual.
• Long -term recovery: For a longer time necessary for recovery after illness.
• Chronic fatigue: A sense of constant fatigue, even after a sufficient rest.
• Digestive problems: Frequent disorders of the stomach, diarrhea or constipation.
• Slow wound healing: Wounds and cuts heal more slowly than usual.
• Frequent rashes on the skin: Eczema, urticaria and other skin rashes.
• Recurrent infections: Repeating infections, such as herpes, thrush and urinary tract infections.

Section 2: Dietrs for immunity: review and classification

Bades (biologically active additives to food) are concentrates of natural or identical biologically active substances that are intended for direct intake with food or introduction into food products.

2.3 mechanisms for the action of dietary supplements for immunity

Dietary supplements for immunity can have a different effect on the immune system, depending on their composition and the mechanism of action:

• Strengthening immune cells: Some dietary supplements, such as vitamin C and zinc, can stimulate the formation and activity of immune cells, such as leukocytes and NK cells.
