One of such elements that seem to be recurring is the clamor for an increase in consumption of Omega-3 fatty acids, but ever stopped to wonder why all the fuss about Omega-3?

This begs the question: What exactly is Omega-3 and why is it so important? Continue reading to find out.

What Is Omega 3 Fatty Acid?

Well, for starters, Omega-3 fatty acids which are also referred to as w-3 or n-3 fatty acids are polyunsaturated fats that have a double bond in the hydrocarbon chain from the third carbon atom from the end of the carbon chain.

That is a just a fancy way of saying that they have unique connections that allow them to be more adaptable and interactive with fatty acids.

As to the origin of the name of this fatty acid, the carbon chain starts with the ‘alpha end’. The other or opposite end which closes the chain is the ‘Omega end’. The ‘3’ in Omega-3 stems from the fact that the first double bond can be found three carbon atoms from the ‘omega end’.

The double bonds present in Omega-3 fats are placed in such a special position that they can basically not be seen or gotten in other fats. This adaptability and interactivity characteristic of Omega-3 fats, although a major plus, makes them more susceptible to damage.

Omega-3 fats are a family of fatty acids which are necessary for human health. These fats have been known not only to be essential to human well-being but also instrumental in facilitating brain function as well as growth and development of the body. It’s a pity, however, that our bodies cannot produce them.

As such, we have to find a way to get them into our bodies. What better way to do this than through our diet? In order to successfully ensure that we consume the right amount of Omega-3, it is imperative that one knows the different types of omega-3 fats available and the right proportions in which our bodies require them.

Types Of Omega-3 Fats

There are different types of Omega-3 fats. The science of cooking has them pegged at 11. Of these 11, however, 3, in particular, stand out. They are Alinoleic acid (ALA), Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA).

Alinoleic acid (ALA)

Alinoleic acid or ALA, as it is popularly called, is often termed to be simpler than other Omega-3 fats. The human body is not capable of producing ALA on its own and so we have to consume foods that contain it in order not to be deficient.

It is an established fact that the body cannot make ALA. Notwithstanding, it can convert it to EPA and DHA, albeit at a low ratio. This means that after conversion it is never the same quantity. A large quantity of ALA, even with the presence of sufficient enzymes will produce a very small amount of EPA and DHA.

Eicosapentaenoic Acid (EPA)

Eicosapentaenoic acid or EPA is another vital Omega-3 fat. Unlike ALA, EPA can be produced by the body. The body does this by converting the ALA it has consumed into active energy.

Docosahexaenoic Acid (DHA)

The third Omega-3 fat, Docosahexaenoic acid or DHA is also essential to the body. It is present in virtually every cell in the body. The body stores it in large quantities in the brain and in the eye, particularly the retina. DHA can help guard against macular degeneration; which can lead to impaired eyesight or loss of complete sight.

What Are The Omega 3 Benefits?


Various organizations concerned with health and nutrition, including the World Health Organization, has campaigned for an increase in daily intake of Omega-3. Why is this? What makes Omega-3 fats special?

They are a vital part of cell membranes all over the body and influence the performance of the cell receptors in these membranes. They also connect to receptors in cells that control genetic function. Apart from these, Omega-3 fats provide quite a myriad of benefits to the body.

They include:

1. Help Reduce Depression

Health Benefits Of Omega 3


Over the years, there have been mixed conclusions about the ability of Omega-3 to relieve depression. Some studies revealed that people who combined omega-3 fatty acids with prescription antidepressants showed greater improvement in symptoms than those who took only antidepressants. Although some studies have found no benefit, Omega-3 has been known to reduce depression.

Five researchers (Sharupski KA, Tangney CC, Li H, Evans DA and Morris MC) published a report in the Journal of Nutritional Health and Aging in 2013. Their study was designed to test if a regular intake of a Mediterranean diet over time would have an impact on depression among older adults.

After an average follow-up of 7.2 years, they discovered that people with adherence to a Mediterranean diet, which is said to be rich in Omega-3 fats, had less likelihood of being depressed. They concluded that intake of such diet may help prevent depression in older age.

Other studies have shown that a proper consumption of foods high in Omega-3 as well as nutritional interventions like Omega-3 supplements can cause a reduction in a person’s chances of falling into depression. In certain cases, when people with depression or anxiety start taking omega-3 supplements, their symptoms get better.

It appears that out of the essential omega-3 fatty acids; ALA, EPA and DHA, EPA is likely to be the best at fighting depression.

2. Improve Vision

Health Benefits Of Omega 3

Intake of foods that are high in Omega-3s can lead to improved vision. This is because of Omega-3, DHA, in particular, is one of the main components of not only the brain but the retina as well.

DHA is responsible for about 60% of the polyunsaturated fatty acids present in the retina. As such, a diet that is deficient in DHA might lead to bad eye health and in turn, problems with sight.

No wonder, therefore, that many children who are fed with a formula enriched in DHA sometimes have better eyesight than those who are not. Funny enough, increase in consumption of Omega-3 has been shown to have a correlation with decreased risk of macular degeneration.

Macular degeneration is often a result of deterioration of part of the retina. It is currently considered as a disease with no cure. It is also one of the highest causes of vision loss and impaired sight.

3. Promote Brain Health

Health Benefits Of Omega 3

The brain stores Omega-3 in abundance because it is an important element in brain growth and development. Doctors often encourage parents to ensure that their infants are given formulas that are fortified with DHA.

One reason for this is that DHA accounts for about 40% of the polyunsaturated fats in the brain and infants need this for their brains to develop well. Pregnant mothers are also not left out. It is recommended that they take lots of Omega-3 to improve the growth of the fetus.

They do not stop this after birth but go a step further to guarantee brain health during the child’s early life. Ingestion of Omega-3 has been linked to improved cognitive performance, brain development, high intelligence as well as improved communication and social competence.

In addition, low levels of Omega-3 have been found in people with mental decline and disorders. Notwithstanding, research has shown a higher intake Omega-3 supplements can reduce the occurrence of their symptoms. This implies that that mood swings and relapses common with folks with schizophrenia, Alzheimer’s and bipolar disorders can be reduced. Wonderful!

4. Prevent Heart Disease

Health Benefits Of Omega 3

One other benefit of Omega-3 is that it can help prevent heart disease by reducing the risk factors associated with it.

In recent times, strokes, heart attacks, and other heart diseases have become major causes of death around the world. What some people do not know is that in times past, Omega-3 had helped to reduce instances of such events.

Researchers noticed that when compared with other population, communities that eat a lot of fish had reduced rates of heart diseases. They narrowed this down to the intake of Omega-3 fats which fishes have a lot of.

In terms of heart health, Omega-3 fats are very essential. They have been shown to cause a reduction in blood pressure and cholesterol levels. They can lead to a reduction in triglycerides and blood pressure in people with high blood pressure.

They are capable of decreasing ‘LDL’ levels and raising good HDL levels. LDL is considered ‘bad cholesterol’ while HDL is ‘good cholesterol’.

Omega-3 can also prevent blood platelets from clustering together, thereby averting the development of harmful blood clots. Furthermore, they can help guard against plaque by keeping the arteries free from obstructions and damage. There is the chance that omega-3 fats can reduce inflammation by limiting the production of particular materials emitted during an inflammatory reaction.

As interesting as all these benefits sound, there is a sad tinge to it. The bitter truth is that there is no compelling proof to show that Omega-3 supplements avert strokes and heart attacks. The bottom line is that they can lessen the factors that might put one at risk of heart attacks or strokes but do not guarantee that one would not have them.

Having the right amount of DHA in the body brings about healthy cells. This helps to produce supple and wrinkle-free skin. EPA is also helping the skin in a number of ways, including; improving hydration, reducing aging, preventing some skin infections as well as managing oil production.

Omega-3s can also shield your skin from sun damage. EPA helps block the discharge of substances that destroy the collagen in your skin after exposure to the sun.
