Omega-3: benefit and use

Section 1: What is omega-3 fatty acids? Fundamental aspects

Omega-3 fatty acids is a group of polyunsaturated fatty acids (PNS) vital for human health. They relate to indispensable fatty acids, which means that the body is not able to independently synthesize them in sufficient quantities, and they should come with food or additives. The term “omega-3” refers to the position of the first double bond in the fatty acid molecule located on the third carbon atom from the methyl (omega) of the end.

There are various types of omega-3 fatty acids, but the most important and well-studied are:

Alpha-linolenic acid (Alk or ALA): This is a vegetable omega-3 fatty acid contained in products such as linseed seeds, chia seeds, walnuts and canols. Alk is the predecessor of other omega-3 fatty acids-EPK and DGK. However, the effectiveness of the transformation of the ALK into the EPC and the DGC in the human body is relatively low and varies depending on the genetic factors, diet and general health.
Eicopentenic acid (EPK or EPA): This omega-3 fatty acid is most often found in seafood, such as fatty fish (salmon, mackerel, herring) and algae. EPC plays an important role in reducing inflammation in the body and maintaining health of the cardiovascular system.
Dokosagexenic acid (DGK or DHA): Just like the EPK, DGK is mainly contained in seafood. It is the main structural component of the brain, retina and sperm. DGC plays a critical role in the development of the brain and visual function, especially during pregnancy and early childhood.

1.1 Chemical structure and properties:

Omega-3 fatty acids are characterized by the presence of several double bonds in the hydrocarbon chain. These double bonds make them more flexible and fluid than saturated fatty acids. This structure affects their function in the body, in particular, on maintaining the fluidity of cell membranes.

ALK (C18: 3 N-3): Contains 18 carbon atoms and 3 double bonds.
EPA (C20: 5 N-3): Contains 20 carbon atoms and 5 double bonds.
DGK (C22: 6 N-3): Contains 22 carbon atoms and 6 double bonds.

Unsaturated fatty acids are more prone to oxidation, especially when exposed to heat, light and oxygen. Therefore, it is important to properly store products and additives, rich omega-3 to prevent their spoilage.

Section 2: Omega-3 action mechanisms in the body:

Omega-3 fatty acids have a wide range of biological effects, interacting with various molecular targets and signal routes in the body.

2.1 influence on inflammation:

One of the most famous Omega-3 action mechanisms is their ability to reduce inflammation. EPK and DGC serve as predecessors for the formation of eicosanoids, such as prostaglandins and leukotrienes who have anti -inflammatory properties. Unlike eicosanoids derived from omega-6 fatty acids (for example, arachidonic acid), eicosanoids derived from omega-3, less inflammatory or even have an anti-inflammatory effect.

Reducing the level of pro -inflammatory cytokines: Omega-3 can suppress the production of pro-inflammatory cytokines, such as the factor of the necrosis of the alpha tumor (TNF-α) and Interleukin-1 beta (IL-1β).
Improving the level of anti -inflammatory mediators: They can stimulate the production of anti -inflammatory mediators, such as resolvines and protectins, which contribute to resolving inflammatory processes.
Inhibiting the activity of enzymes involved in inflammation: Omega-3 can inhibit the activity of enzymes, such as cyclooxygenase-2 (COO-2) and lipoxygenase (log), which are involved in the synthesis of pro-inflammatory eicosanoids.

2.2 influence on the cardiovascular system:

Omega-3 fatty acids have a positive effect on various aspects of the cardiovascular system.

Reducing the level of triglycerides: Omega-3 effectively reduce the level of triglycerides in the blood, which is an important risk factor for cardiovascular diseases.
Reduced blood pressure: Omega-3 can provide a slight, but clinically significant decrease in blood pressure, especially in people with hypertension.
Improving the function of the endothelium: Endothelium is the inner layer of blood vessels, which plays an important role in the regulation of blood flow and maintain the health of blood vessels. Omega-3 can improve the function of the endothelium, contributing to the expansion of blood vessels and a decrease in the risk of blood clots.
Reducing the risk of blood clots: Omega-3 can reduce platelet aggregation, thereby reducing the risk of blood clots that can lead to heart attack or stroke.
Cold rhythm stabilization: Omega-3 can help stabilize the heart rhythm and reduce the risk of arrhythmias, especially ventricular arrhythmias.

2.3 influence on the function of the brain:

DGC is the main structural component of the brain, and therefore Omega-3 play an important role in cognitive functions and brain health.

Maintaining the structure and function of neurons: DGC is a key component of cellular membranes of neurons, ensuring their fluidity and normal functioning.
Improving the transmission of nerve impulses: Omega-3 can improve the transmission of nerve impulses, facilitating the connection between neurons.
Protection from neurodegenerative diseases: Studies show that omega-3 can have a protective effect against neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease, by reducing inflammation and oxidative stress in the brain.
Improving mood and reducing the risk of depression: Omega-3 can affect the mood and reduce the risk of depression, probably due to the modulation of neurotransmitter levels, such as serotonin and dopamine.

2.4 impact on the health of the eyes:

DGC is the main structural component of the retina of the eye, and therefore Omega-3 is necessary to maintain the health of the eyes and visual function.

Maintaining visual acuity: DGC plays an important role in the functioning of photoreceptors in the retina, providing visual acuity.
Reduction of the risk of age -related macular degeneration (VMD): Studies show that Omega-3 can reduce the risk of developing the VMD, the main reason for loss of vision in older people.
Relief of the symptoms of dry eyes: Omega-3 can help alleviate the symptoms of dry eyes, reducing inflammation in the lackeys and improving the quality of the lacrimal film.

2.5 Other action mechanisms:

In addition to the above, omega-3 also have other important effects on the body:

Influence on the expression of genes: Omega-3 can affect the expression of genes, regulating the activity of transcription factors, such as PPAR (peroxisis proliferators-activated receptors).
Influence on the immune system: Omega-3 can modulate the activity of immune cells, reducing inflammatory reactions and increasing resistance to infections.
Influence on glucose metabolism: Omega-3 can improve insulin sensitivity and contribute to the regulation of blood glucose levels.

Section 4: Omega-3 sources: diet and additives

There are two main ways to obtain omega-3 fatty acids: through a diet and through additives.

4.1 Food sources:

Fat fish: Fat fish, such as salmon, mackerel, herring, sardines and tuna, is an excellent source of EPK and DGK. It is recommended to consume fatty fish 2-3 times a week. It is important to take into account the source of fish and avoid fish with a high content of mercury.
Seafood: Other seafood, such as shrimp and mussels, also contain omega-3, although in smaller quantities than fat fish.
Flaxseed and linseed oil: Flue seed and linseed oil are rich sources of Alk. However, as mentioned earlier, the transformation of the Alc into EPC and the DGC in the human body is relatively ineffective.
Seeds of Chia: Chia seeds are also a good source of Alk.
Walnuts: Walnuts contain Alk and can be a useful addition to a diet.
Canol oil: Canol oil contains Alk, but it should not be heated to high temperatures, as this can damage fatty acids.
Enriched products: Some products, such as eggs, milk and yogurt, are enriched with omega-3 fatty acids.

4.2 Omega-3 supplements:

Fish oil: Fish oil is the most common type of Omega-3 additive. It contains EPK and DGK. It is important to choose high -quality fish oil that has undergone molecular distillation for the removal of pollutants, such as mercury and polychlored bifeniles (PHB).
Crichail oil: Crile oil is an alternative source of omega-3. It also contains EPK and DGK, as well as antioxidant Astaxantin. Crile oil is considered more bioavailable than fish oil, which means that EPK and DGK are better absorbed by the body. However, Cricle oil is usually more expensive than fish oil.
Algae oil: Algae oil is a vegan source of omega-3. It contains DGK and is suitable for people who do not consume fish or seafood.
Flax seed oil: Flax seed oil contains Alk and is suitable for vegetarians and vegans. However, it should be remembered that the transformation of the ALK into EPK and DGC in the human body is relatively ineffective.

4.3 Selecting Omega-3 additives:

When choosing an Omega-3 additive, the following factors should be taken into account:

Content of EPK and DGK: It is important to check the content of the EPK and DGK in the addition. Most adults are recommended to consume at least 500 mg of EPK and DGK per day.
Quality and cleanliness: Choose high -quality additives that have undergone molecular distillation to remove pollutants.
Source: Consider the various sources of Omega-3, such as fish oil, kriely oil and algae oil, and choose the one that best corresponds to your needs and preferences.
Price: Compare prices for various additives and select the one that offers the best price ratio.
Reviews: Read the reviews of other users to get an idea of the quality and effectiveness of the additive.

Section 5: Dosage and safety omega-3

5.1 Recommended dosage:

The recommended dosage of omega-3 fatty acids varies depending on individual needs and health status.

General prevention: For general prevention, it is recommended to use at least 500 mg of EPK and DGK per day.
Cardiovascular diseases: People with cardiovascular diseases are recommended to use 1000 mg of EPK and DGK per day.
Depression: For the treatment of depression, higher doses of omega-3, up to 2000 mg of EPK and DGK per day may be required.
Pregnancy: Pregnant and lactating women are recommended to consume at least 300 mg dgk per day.
Children: The dosage of omega-3 for children varies depending on age and weight. Consult a doctor to determine the optimal dosage for your child.

5.2 Safety and side effects:

Omega-3 fatty acids are usually safe when consumed in recommended doses. However, in some cases side effects may occur:

Disorder of the gastrointestinal tract: High doses of omega-3 can cause an disorder of the gastrointestinal tract, such as nausea, diarrhea and bloating.
Fish taste: Some people may experience a fish taste after eating fish oil.
Bleeding: Omega-3 can dilute blood, so caution should be taken to people taking anticoagulants, such as warfarin.
Interaction with drugs: Omega-3 can interact with some drugs, so it is important to consult a doctor before taking additives, especially if you take any medicine.

5.3 Contraindications:

Allergy to fish or seafood: People with allergies to fish or seafood should avoid the use of fish oil and Cricille oil.
Blood coagulation diseases: People with blood coagulation diseases should consult a doctor before taking Omega-3 additives.

Section 6: Omega-3 and Omega-6: Balance importance

Omega-3 and omega-6 fatty acids are two main types of polyunsaturated fatty acids. They are both necessary for health, but it is important to maintain the correct balance between them.

6.1 omega-6 fatty acids:

Omega-6 fatty acids are found in vegetable oils, such as sunflower, corn and soy oil. The main omega-6 fatty acid is linoleic acid (LA). LA is transformed in the body into arachidonic acid (AA), which is a predecessor for the formation of pro -inflammatory eicosanoids.

6.2 Balance importance:

The modern Western diet, as a rule, contains too much omega-6 and is not enough omega-3. This can lead to an increase in inflammation in the body and an increase in the risk of developing various diseases.

The ideal ratio of omega-6 to omega-3 is approximately 1: 1 or 2: 1. However, in the Western diet, this ratio often reaches 10: 1 or even 20: 1.

6.3 how to improve balance:

Reduce omega-6 consumption: Limit the consumption of vegetable oils such as sunflower, corn and soy oil.
Increase omega-3 consumption: Eat more fatty fish, linen seeds, chia seeds and walnuts.
Take Omega-3 additives: Consider the possibility of taking Omega-3 additives to increase the consumption of EPC and DGK.

Section 7: future areas of omega-3 research

Studies of Omega-3 fatty acids continue, and new discoveries and development are expected in the future.

7.1 Individualized approach:

In the future, it can become possible to adapt the dosage of Omega-3 to the individual needs of each person, given the genetic factors, diet and health status.

7.2 New sources Omega-3:

Studies of the new sources of Omega-3, such as micro-crossbars and genetically modified plants, can provide more stable and affordable sources of these important fatty acids.

7.3 New therapeutic applications:

Studies continue to study the potential therapeutic applications of Omega-3 for various diseases, such as cancer, autoimmune diseases and neurodegenerative diseases.

7.4 Act mechanisms:

Further studies of the Omega-3 action mechanisms will help to better understand how these fatty acids affect the body and how they can be used to improve health.

Section 8: Conclusion (must be excluded from the final text)

Although, according to the task, the conclusion is not allowed, it is important to note that omega-3 fatty acids are vital nutrients that play an important role in maintaining health. Maintaining a sufficient omega-3 level in the body through a diet and/or additives can benefit the cardiovascular system, brain, vision and general health. It is important to consider various factors, such as the source, dosage and potential side effects, when choosing omega-3 additives. Consultation with a doctor can help determine the optimal approach to Omega-3 consumption for your individual needs.
