Scientists are astounded by the effects of this nutrient on our brain health – and terrified of the consequences of not getting enough. That nutrient is Omega 3s.
Omega-3s are a group of fatty acids that are essential to brain health & heart health. We cannot produce them naturally – instead they must be introduced through our diet.
The three most important omega-3 fatty acids include ALA, EPA, & DHA
- ALA is mostly found in plants & seeds (flax seeds, chia seeds, spinach, broccoli, tomato)
- EPA/DHA is mostly found in fatty fish (salmon, mackerel, sardines, algae)
Although EPA & DHA are the most easily absorbed by the body, all 3 are beneficial.
Researchers have found a link between ALA and lower risk of cardiovascular disease. It has also been shown to support eye health – including improved sharpness of vision, and the prevention of macular degeneration.
EPA/DHA supports brain health, heart health, & eye health. It is effective in treating chronic inflammation, arthritis, allergies, and cancer.
Depression
One of the more interesting finding is that EPA/DHA is especially effective in treating mood disorders. A 2009 study from Ben Gurion University found that EPA helped with three major types of depression:
- major depressive disorder
- post-partum depression
- bipolar depression.
(These results were mirrored by a number of other scientific publications)
The reason for this is that EPA/DHA is a building block of brain cells and is responsible for the formation of the central nervous system. Not only does it slow cognitive deterioration as you age, but it helps infants develop motor skills and verbal comprehension. Studies have shown that infants who do not get adequate levels of DHA early in life are more likely to develop learning disabilities and depression.
DHA/EPA has also been shown to reduce symptoms of schizophrenia.
