17 Rewarding Health Benefits of Omega 3s

Omega 3 fatty acids are imperative for the betterment of the overall health. A human body is unable to produce omega 3 acids on its own and therefore these fatty acids are considered to be “essential” for the body and it is mandatory for one to consume it.

When a question is raised about the benefits of omega 3 fatty acids then we come to know, very rarely any nutrient possesses so many positive qualities as this compound does. It reduces the risks of a heart disease which is a commonly known advantage of omega 3. Besides this there many other plus points of including omega 3 as a part of the regular diet like improving retinal function, fetal development, weight management, the acids also support the overall well-being of an individual.

It has been approved by the scientists that 2 of the omega 3 formulations can be used for the treatment of high triglycerides. One of the two formulations contains only 1 compound whereas the other one contains the omega 3 fatty acids that are animal-based along with DHA and EPA.

Omega-3 Fatty Acid’s Structure

Omega 3s consists of more than just a singular double bond as their chemical structure, which makes it a particular form of fatty acid that is polyunsaturated in nature. The “3” in the term omega 3 depicts the specific location of the primary double bond in the chemical structure. Saturated fatty acids can be synthesized by the human body, but however the body does not possess the enzyme that has the capability of allowing the double bond to stick in the correct place so as to create omega 3.

There are 3 types of omega 3s found in edibles, EPA, ALA and DHA.

Eicosapentaenoic Acid (EPA): EPA can be found in algae oil, oily fish and krill oil. It is the 20-carbon fatty acid. The body is capable of synthesizing the EPA molecule in the original form. For actually imbibing the whole lot of benefits offered by the EPA and even DHA, one needs to consume food that contains high quantities of these compounds.

Alpha-linolenic Acid (ALA): it is a form of plant-based omega 3. It is mainly found in green and leafy vegetables, chia seeds, flaxseeds and canola, soybean and walnut oils. This compound is a short chain of omega 3 which the body needs to convert into a longer chain of DHA and EPA for actually being able to synthesize ALA. However, this is an inefficient procedure where around 1% of the consumed ALA is finally converted to longer chains of EPA or DHA (in women this percentage is a bit higher).

Docosahexaenoic Acid (DHA): DHA is found in krill oil, oily fish as well as algae oil, just like EPA. This is a 22-carbon molecule. If consumption of DHA becomes higher than the body converts the excess DHA into EPA to maintain equality between EPA and DHA.

Omega 3 Deficiency

Maximum people do not get the right amount of omega 3 fatty acids and for acquiring a suitable amount of it one can have 2 or more oily fish preferably of 3.5 ounces, per week.

Doctors prescribe a meal containing a combined amount of 250-500 mg of DHA and EPA, per day. This will be enough to sustain a healthy individual. But, people with more serious problems like severe heart diseases or other heart problems, cancer, anxiety and depression and possibly lot more conditions. In this case, benefiting from omega 3 is only possible if an individual receives greater doses of it, around 4000 mg every day for a specific heart disorder.

One can surely be deficient in omega 3 and there are certain symptoms of recognition of the condition. These symptoms include poor memory, fatigue, dry skin, mood swings, heart disorders, and depression as well as poor circulation. According to researchers, among the many aspects of risks that leads to death omega 3 deficiency ranks 8th in the list.

To get all the benefits from omega 3, one needs to be on a proper diet that includes food that has a high content of omega 3. But it can be tough for some people who cannot readily get hands such food items. It that case, one can resort to omega 3 supplements and a wholesome diet.

17 Rewarding Health Benefits of Omega 3s

  1. Improves Eye Health

    The major constitutional element of the retina and the brain is DHA. DHA is also a form of omega 3. Therefore, on being deficient of omega 3 one can suffer from vision problems. Even macular degeneration, a popular reason for permanently damaging the eyes and causing blindness, is reduced by a great percentage.

  2. Helps in Promoting Brain Health at the Time of Pregnancy and Infant Life

    We have seen that omega-3s are essential for brain health and growth. Omega-3s are also essential for the development of the infants. DHA constitutes 40% and 60% of the polyunsaturated fatty acids of the brain and the retina, respectively. Hence, if infants are given proper dosage of DHA-fortified formulae then they will have improved eyesight rather than the ones without it. During pregnancy, expecting mothers and their children both get benefited on getting sufficient omega 3s. The children are born with a higher level of intelligence, they possess better social and communication skills, the risk of delayed development decreases, behavioral problems are reduced, lesser risk of autism, ADHD as well as cerebral palsy.

Moreover, on taking the supplements, the symptoms get reduced. Among the 3 forms of omega 3 fatty acids, EPA fights against depression.

  4. Supports in Lessening the Risk Factors against Heart Diseases

    In the present scenario cases of death by strokes and heart attacks have increased immensely. Many years ago, researchers noticed that the communities that had fish as a part of their stapled diet were experiencing lesser heart attacks rather than those who did not. It was later discovered that this was partly due to the presence of omega 3 in fish. From then onwards, omega 3 has proved to be extremely helpful in reducing heart diseases.

    Blood Pressure: Omegas 3s are helpful in reducing blood pressure in people who have high blood pressure.

    Triglycerides: Triglycerides can be reduced within the span of 15%-30% with consumption of omega 3s.

    Plaque: Omega 3 hinders the formation of plaque that can harden and restrict arteries by keeping them free from damage and smooth.

    Blood Clots: Omega 3 prevents the clumping of blood platelets to one another therefore, preventing the possibilities of any unhealthy and dangerous blood clots.

    Inflammation: During an inflammatory response, omega 3s decreases the release of some substances which lessens inflammation.

    HDL-Cholesterol: omega 3 has the capability of raising the good HDL cholesterol levels.

    In some cases, omega 3 is also seen to reduce the bad LDL cholesterol but in many other cases it is found not to work in a similar fashion but in the opposite way.

    However, with all the good qualities that omega 3s possess, there can be no guarantee that a heart attack or a stroke can be surely prevented with its help.

  5. Reduces the Metabolic Syndrome Symptoms

    Metabolic syndrome is a collection of disorders. These disorders include central obesity or what we call bell fat, high triglycerides, increased level of blood pressure, insulin resistance and low levels of HDL. In concern of public interest, this syndrome needs to be cured because it can give rise to or increases the risk of contracting various other diseases. It includes diabetes and heart disease. Omega 3s has the capability of reducing inflammation and insulin resistance, therefore, improving the condition of the heart in people suffering from metabolic syndrome.

  6. Reduces Signs of ADHD among Infants

    ADHD stands for Attention Deficit hyperactivity disorder, a behavioral disorder. It can be distinguished by hyperactivity, inattention and impulsivity. Studies have established that infants with ADHD have decreased the quantity of omega 3 fatty acids in their blood when compared to the healthy contemporaries. This situation can be tackled by taking omega 3 supplements. Omega 3 is helpful in improving attentiveness and the capability of completing tasks. It reduces impulsiveness, aggression, hyperactivity and restlessness. Recent studies have found the evidence for various treatments for ADHD. Fish oil was found to be very effective in curing this.

  7. Helps In Fighting inflammation

    Inflammation is absolutely crucial as it helps in repairing damage and fighting infections inside the body. But, at times, inflammation continues for a lengthier period of time even if there are no infections or injuries in the body. This situation is known as chronic inflammation. Chronic inflammation may contribute to nearly every chronic disease which includes cancer and heart ailments. Here, omega 3 acids have the potential to reduce the yielding of substances and molecules related to inflammation, like the cytokines and the inflammatory eicosanoids. Research has constantly shown the connection between higher levels of omega 3 and reduced level of inflammation.

  8. Helps In Improving Mental Disorders

    Deficiency of omega 3 in people may as well lead to psychiatric disorders. Therefore, for coming out of such a situation, one needs to get proper omega 3 supplements. These supplements can decrease relapses in an individual suffering from schizophrenia or bipolar disorder, it also handles the problem of mood swings. If a person is showing violent behavior, omega 3 fatty acid supplements can give relief from it.

    Ageing can lead to decline in mental health and thus cause the malfunction in the brain functions. For resolving such a problem, the intake of omega 3 is essential for reducing mental decline as a result of ageing. Omega 3 can also help in reducing the risk of Alzheimer’s disease. Moreover, analysis has brought forward that people who consume fatty fish are regarded to possess increased amounts of gray matter which is responsible for processing memories, information and emotions.

  10. Serves In Fighting Autoimmune Diseases

    The autoimmune disease is the disease in which the immunity system of the body mistakes healthy bodily cells with foreign cells and hence attacks them. The best example of this is type 1 diabetes. In this situation, the cells of the pancreas, producing insulin, are attacked by the immune system. Omega 3 thus fights most diseases of this sort and is essential for the younger section of the life. Studies have shown that consuming sufficient amount of omega 3 in the initial years of life is related to decreased risks of a handful of autoimmune diseases that include, autoimmune diabetes found in adults, type 1 diabetes and multiple sclerosis. Other diseases that can be cured or prevented by omega 3 are rheumatoid arthritis, lupus, ulcerative colitis, psoriasis and Crohns’s disease.

  11. Assists in Preventing Cancer

    Omega 3 fatty acids have been claimed for a long time to be able to prevent the incurable disease. Cancer can be deadly if it spreads uninterruptedly inside the body. Nevertheless, it has been proved that people who include omega-3 rich foods in their regular diet have 55% lower chances of contracting colon cancer. It also has been connected to the possibility of lowering the chances of having (in men) prostate cancer and (in women) breast cancer. But, there are some studies that have a different viewpoint.

  12. Reduces Asthma Mostly in Children

    A chronic lung ailment called Asthma has the symptoms like shortness of breath, coughing and wheezing. Extreme asthma attacks are really dangerous. This disease is caused due to swelling and inflammation in the passages of air leading to the lungs. The rate of children with asthma has heightened because of the excessive pollution. Omega 3, therefore, is considered to have the capability of lowering the chances of having asthma in young adults and children.

Trouble in sleeping in children, as well as obstructive sleep apnea seen in adults, can be linked to low omega 3 levels in the body. DHA deficiency is associated with decreased level of hormone melatonin that helps in falling asleep. Both adults and children can enjoy long hours of quality sleep if they take omega 3 supplements on experiencing disturbed sleep.

  17. Assists In Solving Skin Problems

    DHA is responsible for a healthy skin because it is the skin’s structural component. DHA protects the cell membranes, that constitute a huge portion of the skin, and also keeps them healthy. A soft, supple, wrinkle-free and moist skin are signs of wholesome cell membranes. Even EPA is beneficial for the skin in many ways. The following functions are performed by EPA:

    • Hair follicles are protected from hyper keratinization.
    • Prevents acne
    • Prevents ageing of skin before time.
    • Hydration of skin is maintained.
