Omega-3s are essential fatty acids, meaning our body cannot produce them and we have to get them through our diet. There are three kinds of Omega-3s; DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid), and ALA (alpha-linolenic acid ). DHA and EPA are most commonly found in fatty fish like wild caught salmon, sardines, and mackerel. ALA on the other hand is found in plant based foods like some nuts ( Example, walnuts) and seeds (like chia and hemp seeds). 

Unfortunately in western countries, specially United States, we are not consuming enough Omega-3s (1).

there are several important health benefits in consuming omega 3 rich foods. Here I would like to focus on the top 5 proven health benefits of consuming a diet rich in omega-3s:

Omega-3s can fight depression and anxiety:

Studies have found that people who consume diets rich in Omega-3s are less likely to suffer from depression (2).

EPA has been found to be most effective kind of Omega-3 against depression, compare to the other two (ALA and DHA) (3).

Can improve eye health:

A major structure of the brain and retina of the eye is DHA (4).

Consuming enough DHA has been linked to reduction in Macular degeneration, the leading cause of permanent eye disease and blindness (5).

Can promote brain health during pregnancy and early life:

DHA accounts for 40% of the polyunsaturated fatty acids in the brain, and 60% in the retina of the eye (6).

At birth brain weight is 70% of an adult, 15% brain growth occurs during infancy and remaining brain growth is completed during preschool years.  It is recommended that the pregnant and nursing woman should take at least 2.6 g of omega-3 fatty acids and 100-300 mg of DHA daily to look after the needs of her fetus and suckling infant (7).

there has been many benefits associated with getting enough omega-3s during pregnancy including, Higher intelligence, better communication and social skills, less behavioral problems, decreases risk of developmental delay, decreased risk of ADHD, autism and cerebral palsy (8, 9, 10).

Can reduce symptoms of metabolic disorders:

Metabolic syndrome is a collection of conditions. It includes central obesity (belly fat), high blood pressure, insulin resistance, high triglycerides and low HDL levels.

Metabolic syndrome is a major public health concern because it increases ones risk of developing many other diseases including, heart disease and diabetes (11).

Studies have shown that, Omega-3 fatty acids can reduce insulin resistance and inflammation, and improve heart disease risk factors in people with metabolic syndrome (121314).

Can fight inflammation:

Many diseases have been linked to inflammation, specially chronic inflammation, inflammation that persist for long period of time without any signs of injury or infection (15, 16, 17).

Omega-3 fatty acids can reduce the production of molecules and substances linked to inflammation, such as inflammatory eicosanoids and cytokines (1819). Studies shown a link between higher omega-3 consumption and lower inflammation (20, 21).
