Dietary supplements for immunity: strengthen body protection
Section 1: Immunity – the basis of health
-
1 Immune system: body defender
The immune system is a complex network of cells, tissues and organs working together to protect the body from harmful effects, such as bacteria, viruses, fungi and parasites. It recognizes and destroys foreign substances, providing protection against infections and diseases.
1.1.1 Inborn immunity: The first line of defense
Congenital immunity is the first line of protection with which the body encounters pathogens. It includes physical barriers (leather, mucous membranes), chemical barriers (stomach acidity, lysozyme in saliva) and cell components (phagocytes, natural killers). Congenital immunity reacts quickly, but not specific.
1.1.2 Acquired immunity: Adaptation and memorization
Acquired immunity is a more complex and specific protection system that develops in response to the effects of antigens (foreign substances). It includes cellular immunity (T-lymphocytes) and humoral immunity (B-lymphocytes that produce antibodies). The acquired immunity “remembers” antigens, providing a faster and more effective answer with re -contact.
-
2 Factors affecting immunity
The state of the immune system is influenced by many factors, including genetics, age, lifestyle, nutrition, stress and the environment.
1.2.1 Age: Immunity in different periods of life
The immune system develops in childhood and gradually weakens with age (immune aging). Children are more susceptible to infections, since their immune system has not yet been fully formed. Older people are also more vulnerable, since their immune system is less effective.
1.2.2 Nutrition: Key to healthy immunity
Proper nutrition plays an important role in maintaining a healthy immune system. The lack of nutrients (vitamins, minerals, proteins) can weaken the immunity and increase susceptibility to infections.
1.2.3 Stress: The enemy of the immune system
Chronic stress has a negative impact on the immune system, suppressing its function and increasing the risk of infections and diseases.
1.2.4 Dream: Time to restore immunity
The lack of sleep weakens the immune system, reducing the amount and activity of immune cells.
1.2.5 Physical activity: Support for immunity
Moderate physical activity strengthens the immune system, improving blood circulation and stimulating the production of immune cells.
1.2.6 Environment: The influence of toxins
Environmental pollution with toxins (heavy metals, pesticides) can weaken the immune system and increase susceptibility to diseases.
-
3 Signs of weakened immunity
Signs of weakened immunity can vary depending on the degree of impaired immune function.
1.3.1 Frequent colds and infections: More than 6 times a year
Frequent colds and infections (more than 6 times a year) may indicate weakened immunity.
1.3.2 Slow wound healing: A sign of regeneration disorders
Slow wound healing can be a sign of impaired immune function.
1.3.3 Chronic fatigue: A constant feeling of fatigue
Chronic fatigue that is not associated with physical activity may indicate weakened immunity.
1.3.4 Digestive problems: Dysbiosis and immunity
Problems with digestion, such as bloating, diarrhea or constipation, can be associated with a violation of the balance of intestinal microflora, which plays an important role in immunity.
1.3.5 Skin problems: Eczema and allergic reactions
Skin problems, such as eczema, allergic reactions and herpes, may indicate weakened immunity.
Section 2: Dietrs for immunity: Support for the body
