A new meta-analysis of 29 studies involving nearly 4,000 participants reveals that omega-3 fatty acid supplements may significantly reduce aggression. Researchers found up to a 28% decrease in aggression across various demographics and types of aggression, both reactive and proactive. While larger, longer-term studies are needed, the findings suggest omega-3 supplementation could be a valuable tool in managing aggression in various settings, from communities to the criminal justice system. The positive effects on brain health and cardiovascular health further support the potential benefits of incorporating omega-3 into diets.
