Omega-3 fatty acids EPA and DHA are part of the human brain, and are very much involved in the brain biochemistry, physiology and normal functioning. They are important for the renewal of cell membranes, and because of that their deficiency can accelerate the aging of the brain.
Brain membranes have high content of these fats, and human studies suggest that a lack of omega-3s in the brain may induce various mental and behavioural disorders.
On the other hand, researchers have proved that diet rich in omega-3 (from fatty fish or supplements) can prevent or even help many neuropsychiatric conditions, they can decrease stress and anxiety and also delay cognitive decline of ageing.
Omega 3 fatty acids also have anti-inflammatory effect in the body, but if we lack them then the result can be an increase in the levels of inflammation throughout the body and particularly in the brain.
Inflammation in the brain can often go unnoticed, it is on cellular level and it does not cause pain or any other symptoms, but it can interrupt the signalling between cells.
Anti-inflammatory drugs which can decrease the inflammation throughout the body can’t cross the blood-brain barrier, and therefore when it comes to brain inflammation, its only protection are adequate levels of anti-inflammatory omega-3 fatty acids.
Depression, anxiety and some other mental disorders according to some may be a result of inflamed brain, but chronic stress can also be a contributing factor for a development of some of these diseases.
Scientific studies have shown that severe stress caused by major life events, such as divorce, loss of a loved person, loss of a job, or even social isolation can increase damaging oxidative stress in the body.
And the oxidative stress can damage cells and cause a decrease in vital substances, including omega -3 which are important for our health and normal functioning.
Scientists have suggested that when it comes to stress and omega -3, a “vicious cycle” exists, where a low omega-3 status may increase stress-related hormones such as cortisol and adrenaline, and that can cause further decrease in omega-3s.
Fortunately, some trials have shown that omega-3 supplements may reduce cortisol levels and help keep stress and anxiety under control.
Omega-3s are usually obtained from fish or krill oil, but when choosing some of these supplements it is wise to go for a good quality product which has also been tested for major pollutants, and is certified as pollutants free.
