Part 1: The basics of omega-3 and their value for health

1.1. What is omega-3 fatty acids?

Omega-3 fatty acids is a group of polyunsaturated fatty acids (PNS) necessary for human health. They are called “indispensable”, because the body cannot synthesize them independently and should receive them from food or additives. The name “omega-3” refers to the chemical structure of these fatty acids, where the first double bond is located in the third carbon atom from the methyl (omega) of the end of the molecule.

1.2. The main types of omega-3: epa, dha and ala.

There are three main types of omega-3 fatty acids most significant for human health:

ALA (alpha-linolenic acid): It is contained mainly in plant sources, such as linseed oil, chia seeds, walnuts and soybeans. ALA is the predecessor of EPA and DHA, but its transformation into these more useful forms in the human body is limited.
EPA (eicopascentenoic acid): It is mainly contained in fatty fish, such as salmon, mackerel, sardines and herring, as well as in algae. EPA plays an important role in reducing inflammation.
DHA (Docosaexaenoic acid): It is also contained in fatty fish and algae. DHA is the main structural component of the brain, retina and sperm. It is critical for the development of brain and vision, especially in infants.

1.3. The benefits of omega-3 for the cardiovascular system.

Omega-3 fatty acids have a significant positive effect on the cardiovascular system:

Reducing the level of triglycerides: Omega-3, especially EPA and DHA, help reduce the level of triglycerides in the blood, which is one of the risk factors for cardiovascular diseases.
Reduced blood pressure: Omega-3 can contribute to a moderate decrease in blood pressure, especially in people with hypertension.
Reducing the risk of blood clots: Omega-3 has an antitrobotic effect, reducing the risk of blood clots that can lead to heart attack or stroke.
Improving the function of the endothelium: Omega-3 help improve the function of the endothelium-the internal lining of blood vessels, which plays an important role in maintaining the health of blood vessels.
Reduction in risk of arrhythmia: Some studies show that Omega-3 can reduce the risk of arrhythmia (irregular heartbeat).

1.4. The effect of omega-3 on brain health and cognitive functions.

Omega-3, especially DHA, play a critical role in the health of the brain and cognitive functions:

Brainstorming support: DHA is the main structural component of the brain and is necessary for its normal development, especially during pregnancy and infancy.
Improving cognitive functions: Omega-3 can improve memory, attention and other cognitive functions, especially in the elderly.
Reduction in the risk of dementia and Alzheimer’s disease: Some studies show that sufficient consumption of Omega-3 may reduce the risk of developing dementia and Alzheimer’s disease.
Improving mood and reducing the risk of depression: Omega-3 can have a positive effect on the mood and reduce the risk of depression.
Planting nerve cells: Omega-3 has neuroprotective properties, protecting the nerve cells from damage.

1.5. The role of Omega-3 in maintaining the health of joints and bones.

Omega-3 fatty acids can have a positive effect on the health of joints and bones:

Reducing inflammation: Omega-3 has anti-inflammatory properties that can help reduce inflammation in the joints associated with arthritis.
Reducing joint pain: Reception of Omega-3 can reduce joint pain and improve mobility.
Cross fabric protection: Omega-3 can help protect cartilage fabric from destruction.
Improving bone density: Some studies show that omega-3 can help improve bone density and reduce the risk of osteoporosis.
Support for joints of joints with osteoarthritis: Omega-3 can have a reliable effect in osteoarthritis.

1.6. Omega-3 and inflammation: the mechanism of action.

Omega-3 has an anti-inflammatory effect through several mechanisms:

Inhibition of enzymes involved in inflammation: Omega-3 can inhibit enzymes, such as cyclooxygenase (COO) and lipoxygenase (log), which are involved in the production of inflammatory substances, such as prostaglandins and leukotrienes.
Reducing the level of inflammatory cytokines: Omega-3 can reduce the level of pro-inflammatory cytokines, such as the factor of tumor-alpha necrosis (TNF-α) and interleukin-1 beta (IL-1β).
An increase in the production of anti -inflammatory mediators: Omega-3 stimulates the production of anti-inflammatory mediators, such as resolvins and protective.
Influence on the expression of genes: Omega-3 can affect the expression of genes associated with inflammation.
Improving the ratio of omega-6 and omega-3: Omega-3 help to balance the ratio of omega-6 and omega-3 fatty acids in the body, which also helps to reduce inflammation. Omega-6 fatty acids, unlike omega-3, can contribute to inflammation.

1.7. Impact omega-3 vision.

DHA is an important structural component of the retina and plays an important role in vision:

Maintaining the health of the retina: DHA helps to maintain the health of the retina and its normal function.
Improving visual acuity: Enough DHA consumption can improve visual acuity, especially in babies and children.
Reduction of the risk of age -related macular degeneration (VMD): Some studies show that Omega-3 can reduce the risk of developing the VMD-the main cause of loss of vision in older people.
Reducing dry eyes: Omega-3 can help reduce the symptoms of dry eyes.
Support for the health of the eyes with glaucoma: Some studies suggest that Omega-3 can have a positive effect on the health of the eyes with glaucoma.

1.8. Other beneficial properties of Omega-3: skin, hair, immunity.

Omega-3 has a beneficial effect not only on the heart, brain and vision, but also on other aspects of health:

Skin health: Omega-3 can help improve the condition of the skin, reduce dryness, irritation and inflammation in states such as eczema and psoriasis. They can also help moisturize the skin and protection against ultraviolet radiation.
Hair health: Omega-3 can help strengthen hair, improve its shine and reduce loss.
Immune system: Omega-3 play an important role in the regulation of the immune system. They can help modulate the immune response, reduce inflammation and maintain the balance of immune cells.
Pregnancy and fetal development: Omega-3, especially DHA, are extremely important for the normal development of the brain and vision of the fetus. They can also reduce the risk of premature birth.
Mental health: Omega-3 can have a positive effect on mental health, reducing the risk of depression, anxiety and other mental disorders.

1.9. Recommended daily dose of Omega-3.

The recommended daily dose of Omega-3 varies depending on age, health status and individual needs. General recommendations are as follows:

Healthy adults: At least 250-500 mg EPA and DHA per day.
People with cardiovascular diseases: 1000 mg EPA and DHA per day.
People with a high level of triglycerides: 2000-4000 mg EPA and DHA per day (under the supervision of a doctor).
Pregnant and lactating women: 200-300 mg dha per day (in addition to the total consumption of omega-3).
Children: The dosage depends on age and weight. Consultation with a pediatrician is recommended.

It is important to remember that these recommendations are common and can vary depending on individual circumstances. Always consult a doctor or nutritionist to determine the optimal dose of omega-3 for you.

1.10. Symptoms of omega-3 deficiency.

Omega-3 deficiency can be manifested by various symptoms:

Dry skin: Omega-3 help to maintain the moisture of the skin, and their deficiency can lead to dryness, peeling and itching.
Dry eyes: Omega-3 deficiency can contribute to dry eyes, which leads to discomfort, redness and feeling of sand in the eyes.
Fatigue: Omega-3 play an important role in energy exchange, and their deficiency can lead to fatigue and weakness.
Problems with memory and concentration: DHA is an important component of the brain, and its disadvantage can negatively affect memory, concentration and other cognitive functions.
Joint pain: Omega-3 has anti-inflammatory properties, and their deficiency can contribute to increased inflammation in the joints and the development of pain.
Depression and anxiety: Omega-3 can have a positive effect on the mood, and their deficiency may be associated with an increased risk of depression and anxiety.
Heart problems: Omega-3 deficiency can increase the risk of cardiovascular diseases.
Brown nails and hair: Omega-3 help strengthen nails and hair, and their deficiency can lead to their brittleness and loss.

It is important to note that these symptoms can be caused by other causes. For accurate diagnosis of omega-3 deficiency, it is recommended to consult a doctor and take a blood test.
