Omega-3 for the elderly: support for health in adulthood

Chapter 1: What is omega-3 fatty acids?

Omega-3 fatty acids is a group of polyunsaturated fatty acids that are vital for the human body. They are not produced independently, so they must come with food or in the form of additives. The key omega-3 fatty acids include:

Alpha-linolenic acid (Alk): The predecessor of the other two important omega-3 is contained in plant sources.
Eicosapentaenic acid (EPA): Important to the health of the heart and brain.
Docosahexaenic acid (DHA): Critically important for the development of the brain and maintaining cognitive functions.

Alk, being a predecessor, can be transformed into EPC and DGK, but this process in the human body, especially in older people, proceeds ineffectively. Therefore, direct sources of EPK and DGK, such as fat fish, are more important.

1.1 Classification and chemical structure omega-3

Omega-3 fatty acids are characterized by the position of the first double bond in the fat molecule located in the third carbon atom from the methyl end (omega-cow). Their chemical structure determines their unique properties and role in the body.

Alk (C18H30O2): Contains 18 carbon atoms and 3 double bonds. It is a short-chain omega-3.
EPA (C20H30O2): Contains 20 carbon atoms and 5 double bonds. Refers to the long-chain omega-3.
DHC (C22H32O2): Contains 22 carbon atom and 6 double bonds. Also long-chain omega-3.

Double bonds in the fat molecule make them more subject to oxidation, so it is important to ensure adequate consumption of antioxidants.

1.2 sources Omega-3: Food and additives

The best way to get Omega-3 is a balanced diet, including:

Fat fish: Salmon, mackerel, herring, tuna, sardines. It is recommended to use 2-3 portions (about 140 grams) per week. This is the optimal source of EPK and DGK.
Vegetable oils: Flue oil, chia oil, walnut oil, rapeseed oil. Contain Alk, but the conversion to the EPK and DHK is limited.
Seeds: Len, chia, hemp. Good sources of Alk.
Nuts: Walnuts. Contain Alk.
Enriched products: Some eggs, milk, yogurts are enriched with omega-3.

In cases where the consumption of omega-3 with food is not enough, it is recommended to use additives. There are various forms of Omega-3 additives:

Fish oil: The most common form containing EPC and DGK. It is important to choose high -quality additives that have been cleaned of heavy metals and other pollutants.
Krishye fat: Contains EPK and DGK, as well as antioxidant Astaxantin. It is absorbed somewhat better than fish oil.
Algae oil: Vegetarian source of DGK. It is made of microal -seedlings that synthesize DGK.
ALK supplements: They only contain Alk, which is less effective for increasing the level of EPC and DHC in the body.

When choosing additives, it is necessary to pay attention to the concentration of EPK and DGC for a portion. The recommended dosage varies depending on the state of health and goals.

Chapter 2: The role of Omega-3 in maintaining the health of the elderly

With age, physiological changes occur, which increase the need for certain nutrients, including omega-3. Omega-3 play an important role in maintaining the health of the cardiovascular system, brain, vision and joints in the elderly.

2.1 omega-3 and heart health

Cardiovascular diseases (SVD) are one of the leading causes of mortality among the elderly. Omega-3 has a positive impact on various Risk factors of the SVD:

Reducing the level of triglycerides: A high level of triglycerides is a risk factor for the development of SVD. Omega-3, especially EPK and DGC, effectively reduce the level of triglycerides in the blood.
Reduced blood pressure: Omega-3 can provide a moderate decline in blood pressure in people with hypertension.
Prevention of blood clots: Omega-3 has antitrobotic properties, reducing the risk of blood clots and, therefore, strokes and heart attacks.
Improving the function of the endothelium: Endothelium is an internal lining of blood vessels. Omega-3 improve the function of the endothelium, contributing to the expansion of blood vessels and improving blood flow.
Risk reduction of arrhythmias: Some studies show that Omega-3 can reduce the risk of arrhythmias (heart rhythm disorders).

Regular use of omega-3 can significantly reduce the risk of development and progression of SVD in the elderly.

2.2 omega-3 and brain health

With age, cognitive functions, such as memory, attention and speed of thinking, can decrease. Omega-3, especially DHC, play an important role in maintaining brain health and cognitive functions.

The structural component of the brain: DGC is the main structural component of the cell membranes of the brain, making up to 97% omega-3 fatty acids in the brain.
Improving neurotransmissance: Omega-3 participate in the transmission of nerve impulses (neurotransmission), which is necessary for normal brain function.
Protection from neurodegeneration: Omega-3 has neuroprotective properties, protecting the brain from damage caused by aging and neurodegenerative diseases, such as Alzheimer’s disease.
Improving memory and attention: Studies show that the use of omega-3 can improve memory, attention and other cognitive functions in older people.

Adequate consumption of Omega-3 can help maintain cognitive functions and reduce the risk of developing neurodegenerative diseases in old age.

2.3 omega-3 and vision health

Age macular degeneration (VMD) is the main reason for loss of vision in the elderly. DGC is the main structural component of the retina and plays an important role in maintaining visual health.

Support for the structure of the retina: DGC is necessary to maintain the structure and functions of photoreceptors of the retina, cells responsible for the perception of light.
Protection against oxidative stress: Omega-3 has antioxidant properties, protecting the retina from damage caused by oxidative stress.
Risk reduction of the VMD: Studies show that the use of omega-3 can reduce the risk of development and progression of the VMD.
Improving the function of the lacrimal gland: Omega-3 can improve the function of the tear gland and reduce the symptoms of dry eye syndrome, a common disease among the elderly.

Regular use of omega-3 can help maintain vision and reduce the risk of developing age diseases.

2.4 omega-3 and joint health

Osteoarthritis (OA) is a common joint disease, characterized by pain, stiffness and limitation of mobility. Omega-3 has anti-inflammatory properties and can help alleviate the symptoms of OA.

Anti -inflammatory action: Omega-3 inhibit the production of inflammatory substances, such as prostaglandins and leukotrienes who are involved in the development of OA.
Reducing pain and stiffness: Studies show that the use of omega-3 can reduce pain and stiffness in the joints of people with OA.
Improving mobility: Omega-3 can improve joint mobility and facilitate the implementation of everyday tasks.
Carriage protection: Some studies show that omega-3 can protect cartilage from destruction, slowing the progression of OA.

Omega-3 can be a useful addition to the treatment of OA, helping to alleviate the symptoms and improve the quality of life of the elderly.

2.5 omega-3 and immune system

With age, the immune system weakens, which makes the elderly more susceptible to infections. Omega-3 can help support the immune function.

Regulation of inflammatory processes: Omega-3 help regulate inflammatory processes in the body, preventing an excessive inflammatory reaction that can damage tissues.
Improving the function of immune cells: Omega-3 can improve the function of immune cells, such as T cells and B cells, which play an important role in protection against infections.
Risk reduction in autoimmune diseases: Some studies show that omega-3 can reduce the risk of developing autoimmune diseases in which the immune system attacks the body’s own tissues.

2.6 omega-3 and skin health

With age, the skin becomes more thin, dry and subject to damage. Omega-3 can help improve skin health.

Moisturization of the skin: Omega-3 help retain moisture in the skin, making it more moisturized and elastic.
Ultraviolet radiation protection: Omega-3 has antioxidant properties, protecting the skin from damage caused by ultraviolet radiation.
Reduced inflammation: Omega-3 can reduce inflammation in the skin, facilitating the symptoms of skin diseases such as eczema and psoriasis.
Improvement of wound healing: Omega-3 can improve the healing of wounds and other skin damage.

Chapter 3: The recommended dosage of omega-3 for the elderly

The recommended dosage of Omega-3 for the elderly varies depending on their health and goals. General recommendations:

To maintain overall health: At least 250-500 mg of EPK and DGK per day.

Consult a doctor: Before taking the additives Omega-3, you need to consult a doctor, especially if you have any diseases or you take medications.

Chapter 8: We debunk myths about omega-3

There are several myths about Omega-3 that must be dispelled.

Myth 1: All Omega-3 are the same. Alk, EPK and DGK are different types of omega-3, which perform different functions in the body. EPC and DGC contained in fatty fish and additives are more effective for increasing the level of omega-3 in the body than the ALK contained in plant sources.
Myth 2: Omega-3 help from all diseases. Omega-3 has many useful properties, but they are not a panacea. They can help reduce the risk of developing certain diseases, but cannot cure all diseases.
Myth 3: The more omega-3, the better. Too many omega-3 can lead to side effects, such as the disorder of the gastrointestinal tract and bleeding. It is important to follow the recommended dosage.
Myth 4: Omega-3 additives are always safe. Omega-3 additives can interact with some drugs and are contraindicated in some cases. Before taking the additives, you need to consult a doctor.
Myth 5: Vegetarians cannot get Omega-3 enough. Vegetarians can receive DHC from algae oil, which is a vegetarian source of this important omega-3.

Chapter 9: Omega-3 and cognitive health in the context of Alzheimer’s disease

Alzheimer’s disease (BA) is a neurodegenerative disease characterized by a progressive decrease in cognitive functions, including memory, thinking and speech. Omega-3 fatty acids, especially DHC, play an important role in maintaining the structure and function of the brain, and their potential effect on the prevention and slowing of the progression of BA is the subject of intense studies.

9.1. Omega-3 action mechanisms in the brain at ba

Several mechanisms explain how Omega-3 can affect the course of BA:

Reducing the formation of amyloid plaques: Plains, consisting of a beta-amyloid protein, are one of the Hallmarka BA. Studies in vitro and on animal models have shown that DGC can reduce the formation of amyloid plaques and contribute to their splitting.
Reducing the phosphorulation of Tau-Belka: Another pathological sign of BAs are neurofibrillar balls, consisting of phosphorized Tau Belka. DGC can reduce the phosphorylation of Tau-Belka, which reduces the formation of balls and improves the function of neurons.
Anti -inflammatory action: Inflammation in the brain plays a role in the development of BA. Omega-3 has anti-inflammatory properties and can reduce the level of inflammatory cytokines, which protects neurons from damage.
Improving neuroplasticity and synaptic function: Neuroplasticity is the ability of the brain to adapt and form new connections. The synaptic function is important for transmitting information between neurons. DGC helps to improve neuroplasticity and synaptic function, which helps to preserve cognitive functions.
Protection against oxidative stress: Oxidative stress is an imbalance between the production and neutralization of free radicals, which can damage brain cells. Omega-3 has antioxidant properties and can protect neurons from oxidative stress.
Improving cerebral circulation: DGC helps to improve cerebral circulation, which provides neurons with oxygen and nutrients.

9.2. Clinical research on the influence of omega-3 on ba

The results of clinical studies on the influence of Omega-3 on BA are ambiguous. Some studies showed a positive effect, especially in the early stages of the BA, while others did not reveal significant differences between the groups taking omega-3 and placebo.

Research in public with mild cognitive disorders (LKN): LKN is a condition that can precede BA. Some studies have shown that the use of omega-3 can slow down the progression of LCN to BA.
Research in people with a diagnosis of BA: The results of these studies are less unambiguous. Some studies have shown that Omega-3 can improve cognitive functions in people with mild and moderate degree of BA, while others have not revealed a significant effect.
Factors affecting research results: Differences in research results can be associated with various factors, such as:
- Omega-3 dosage: Some studies used higher doses of omega-3 than others.
- Duration of research: Longer studies can identify more significant results.
- Stage BA: Omega-3 can be more effective in the early stages of BA, when brain damage is not so great.
- Genetic factors: Some genetic factors can affect the susceptibility to Omega-3.

9.3. The role of Omega-3 in the prevention of BA

Due to the fact that the treatment of BA in the later stages is difficult, prevention is a key direction of combating this disease. The inclusion of omega-3 in the diet may be one of the elements of the BA prevention strategy.

Animal research: Studies on animal models have shown that the use of omega-3 at an early age can protect the brain from damage associated with BA.
Epidemiological studies: Epidemiological studies have shown that people who use more fish, rich omega-3, have less risk of BA.
Nutrition recommendations: Many experts recommend eating fatty fish 2-3 times a week or taking Omega-3 additives to reduce the risk of BA.

9.4. Additional factors affecting cognitive health

It is important to understand that Omega-3 is not the only thing that affects cognitive health. Other factors, such as:

Healthy nutrition: Diet, rich in fruits, vegetables, whole grain products and low -fat protein, is important to the health of the brain.
Regular physical exercises: Physical exercises improve blood circulation in the brain and contribute to the growth of new neurons.
Cognitive activity: The solution of puzzles, reading, studying new skills and communication help maintain cognitive functions.
Social activity: Social isolation can negatively affect cognitive functions. Maintaining social ties is important for brain health.
Control of risk factors for cardiovascular diseases: High blood pressure, high cholesterol and diabetes can increase the risk of BA.

Chapter 10: Legal and ethical aspects of the use of omega-3 in old age

The use of omega-3 in old age, like any other medical intervention, is associated with legal and ethical aspects that require attention.

10.1 informed consent

Obtaining informed consent is one of the fundamental principles of medical ethics. Before the reception of Omega-3, an elderly person must be informed about:

Aims accept omega-3: What benefit he can get from the reception of omega-3.
Possible risks and side effects: About possible side effects and interaction with other drugs.
Alternative treatment methods: About existing alternative methods of treatment and their effectiveness.
The right to refuse to receive Omega-3: The right to refuse to receive Omega-3 at any time.

Informed consent should be obtained in an understandable form, taking into account the cognitive abilities of an elderly person. If an elderly person is not able to make decisions independently, consent must be received from his legal representative.

10.2 competence and legal capacity

The determination of the competence and legal capacity of an elderly person is important for making decisions on medical treatment, including taking omega-3.

Competence: A person’s ability to understand information, evaluate it and make decisions.
Caution: Legal recognition of a person’s ability to independently exercise his rights and obligations.

If there are doubts about the competence of an elderly person, it is necessary to assess cognitive functions. If a person is recognized as incompetent, the decision to receive Omega-3 should be made by his legal representative, based on the best interests of an elderly person.

10.3 Privacy

The preservation of the confidentiality of medical information is an important ethical and legal obligation. Information about the admission of Omega-3 to an elderly person should be available only to those persons who need it to provide medical care.

10.4 Responsibility of medical workers

Medical workers recommend an Omega-3 to older people are responsible for:

Providing complete and reliable information about Omega-3.
Assessment of the state of health of an elderly person and identifying possible contraindications.
** Side monitoring
