DHA, or specifically docosahexaenoic acid, is an omega-3 fatty acid and serves as a very important structural component of the brain phospholipids, as well as lipids in the nervous system. DHA accumulates rapidly in the human brain during the third trimester of pregnancy and this build-up results in rapid brain tissue development and growth during development. DHA plays a very important role in supporting brain health and is important for normal neural function while playing a key role in the structural development of neural and synaptic membranes. Inadequate availability of DHA or other polyunsaturated fatty acids during fetal and infant development is thought to be a factor in the development of behavioral, functional and neurological disorders.
A research group conducted an in-depth review of over 258 references discussing the importance of DHA in the development of cognition and other brain functions. Their report found positive associations between concentrations of DHA and neurodevelopment. The brain’s need for DHA continues through adult life, as reports show the brain’s cortex continues to undergo active synaptic turnover, an area where DHA has proved so critical. Other studies have also pointed out DHA’s effect on mood and stress. One placebo-controlled double-blind study reported that supplementation with DHA appeared to lower aggression levels during periods of stress while another noted DHA minimized hostility during stressful periods when compared to placebo.Similarly to DHA, EPA (eicosapentaenoic acid) is an important fatty acid which also, in addition to its varied roles in cardiovascular health, promotes the health of the brain and nervous system. Whereas DHA is proven to be an essential component of brain development, EPA appears more focused on behavior and mood. Studies have documented EPA’s effect on improving symptoms of major depression such as mood, feelings of guilt or worthlessness and insomnia. Other studies have also pointed out improvements in aggressive behavior and depression in those with personality disorders. Levels of eicosapentanoic acid are very low in depressed patients and other studies have reported that countries with high rates of fish oil consumption have low rates of depressive disorder. The reason for this is not fully understood but the association is noteworthy.
DHA and EPA provide effects on their own, but the combination provides the most benefits on cognitive function and mood health. In a clinical study assessing the cognitive performance in healthy adults, the DHA/EPA group improved significantly when compared to placebo in the areas of attention and reaction time, as well as anxiety, fatigue, depression and confusion. The authors concluded “DHA/EPA supplementation can improve higher brain functions – sense of wellbeing (vigor), reactivity, attention, cognitive performance and mood – in young, healthy adults.” Reports of dementia risk and cognitive decline and their associations to omega-3 consumption have been reported in a number of research papers.Overall cognitive performance or cognitive decline is related to omega-3 consumption, whereas those who eat more fatty acids have a better cognitive performance and vice versa. Other studies have shown the success of these fatty acids on helping with aggression. As with depression, there are also numerous reports of lows omega-3 levels within the body in those suffering from Attention Deficit Hyperactivity Disorder (ADHD).
Since many adults and children are not getting these important fatty acids in their diet, supplementation is very important in ensuring these benefits are being achieved – especially as the new school year begins!Paul Carlotta is the leading expert in Market America and Nutraceuticals.
