Omega-3 fatty acids are known to help the heart and they have also been found to help defend against eye diseases like macular degeneration.
A study by researchers at the Indiana University School of Medicine shows that omega-3 fatty acids could also help people struggling with alcohol addiction or psychiatric disorders. According to scientists, the DHA in the fatty acid was responsible for “normalizing behavior” in mice. When taking DHA, mice were less likely to become depressed or manic when placed under stress. Unexpectedly, the mice also lost their taste for alcohol when consuming DHA supplements.
We believe a diet rich in omega 3 fatty acids may help the treatment and prevention of bipolar disorder, and may help with alcoholism as well,” says Alexander B. Niculescu, M.D., Ph.D. Source: Science Daily, May 27, 2001
