Wang et al. analyzed 842 articles on primary and secondary prevention They deducted multiple positive effects from an increased intake of omega 3 fatty acids DHA and EPA (in the form of fish and / or supplements). Not only mortality in general decreased, even heart attacks and sudden cardiac death were less frequent. In addition, they noted that increased consumption did not lead to any issues. The Mayo Clinic also conducted a survey showing the protective effect of omega-3 fatty acids on the heart.

When it comes to the percentage of fat in the tissues of the human body, the nervous system has the highest score. Our brain consists of eight percent omega-3 fatty acids, according to Dr. David Horrobin, a leading scientist in the field of essential fatty acids. In our brains, the fatty acid DHA is mainly incorporated into the myelin sheaths that are located around the nerve cells and in the so-called phospholipid membranes. Omega-3-fatty acids are therefore used in the treatment of various mental disorders.

Research among 21 children diagnosed with ADHD shows that they had a significantly greater deficiency of essential fatty acids than the control group. Also, the first group with children showed clearly less good results on tests regarding unrestrained behavior and the temporary processing of information. It is therefore conceivable that children with ADHD consume higher amounts of fatty acids or that they are less able to convert these fatty acids.

In the case of aggression omega-3 fatty acids seem to be able to influence both the behavior of mice and that of humans. Those who take few of these fatty acids are more likely to murderous behavior. People who have been found guilty of public violence, have low blood counts when it comes to these fatty acids. If these people take omega-3 fatty acids over several years, the aggression declines. A number of studies have shown that these fatty acids may have a beneficial effect on impulsive behaviour (and hence aggression).

Andrew L. Stoll et al. were pioneers to demonstrate clinically in a systematic way, the relationship between omega-3 fatty acids and an improved synapsis transfer in the human brain. The researchers gave patients with bipolar disorder (manic-depressive illness), a fish oil supplement for nine months. It remarkably improved the health of these patients compared to a control group. Nowadays, a research is done for the effect of omega-3 fatty acids on how the synaptic impulses are transmitted in the nerve tissue.Omega-3 fatty acids, as research has showed, may have a beneficial effect on the treatment of bipolar disorders

Omega-3 fatty acids seem to have a positive effect on depression. This is the outcome of an analysis made by the American Psychiatric Association (APA) that have been done to research the potentially beneficial effects of these fatty acids. This analysis was carried out by the special omega-3 fatty acid committee of the APA.

Experiments on animals have shown that both the blood flow and the functioning of the brain will benefit from the intake of omega-3 fatty acids. Theoretically, the chance on getting Alzheimer's disease could decrease. However, the present available scientific research, does not confirm this assumption. The results of the investigations sometimes contradict. In other cases, the quality of the studies is questionable.

Epidemiological research shows, that there is a relationship between psychoses and a low consumption of omega-3-fatty acids . Clinical study show that these fatty acids have a positive effect on the treatment of schizophrenia and also contribute to the prevention of this disorder. Research on schizophrenic youngsters shows that the fatty acids are just as effective as the atypical antipsychotics (neuroleptics) that are currently prescribed in schizophrenia

Omega-3 fatty acids have anti-inflammatory properties. Because of this characteristic, these fatty acids were analyzed with regard to inflammatory and autoimmune diseases (for example rheumatoid arthritis, Crohn's disease, etc.). The researchers have already proven the positive effects of omega-3 fatty acids in rheumatoid arthritis.

Omega-3 fatty acids are able to contribute positively to the prevention of the eye disorder macular degeneration (MD). This is shown, for example, by international research: subjects who ate a full-fat fish once a week had fifty percent less chance of developing the above-mentioned condition of the eyes. This effect is mainly related to the consumption of DHA, since this fatty acid is in large quantities in the retina and keeps it in condition. Research also supports the statement that fatty acids of the omega-3 type promote the health of the eye. Thus, the fatty acids contribute to the production of tears, which is necessary to prevent dry eyes.
