Omega-3: An aid to improving mood Omega-3: An aid to improving mood

Research led by the psychiatrist Joseph Hibbeln shows that rates of depression are much lower in countries where there is a high consumption of fish, such as Japan. This is due to the omega-3 fatty acids found in certain seafoods and fish.

Based on these results, scientists at Harvard University began a study to see if omega-3 could be used to prevent or treat depression and other mental disorders. “Two omega-3 fatty acids — eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) — are thought to have the most potential to benefit people with mood disorders,” explains Dr. David Mischoulon on the university’s webpage.

These types of acids, Mischoulon adds, travel easily through brain cells to interact with the molecules related to mood. However, he clarifies that these acids are not a guaranteed treatment. “Analyses generally suggest that the omega-3s are effective, but the findings are not unanimous because of variability between doses.”

In other words, in the right doses, they serve as a natural treatment, “…but we need more research about how they work, how effective they really are, and their long-term safety before we can make conclusive recommendations,” the study concludes.
