Aggressive behaviors, such as hitting, yelling, or threatening, can cause physical or emotional harm to others. Research indicates that poor nutrition may contribute to these behaviors, suggesting that dietary interventions could be helpful strategies for reducing them. A recent review and meta-analysis found that omega-3s can reduce aggressive behaviors by as much as 28 percent in children and adults.

Researchers analyzed the findings of 29 randomized controlled trials investigating the effects of omega-3s on behavior. The trials included more than 3,900 participants and involved children and adults of varying ages.

Their analysis revealed that omega-3s exerted a short-term effect on behavior, with reductions ranging from 16 to 28 percent, regardless of age, gender, baseline diagnosis, treatment duration, or dose. Interestingly, omega-3s reduced reactive aggression (impulsive behavior in response to a perceived threat) and proactive aggression (premeditated to achieve a specific goal).

These findings suggest that omega-3s positively influence behavior in children and adults and offer a potential strategy for moderating behavior problems in multiple settings, including the community, prisons, and clinics.

Omega-3 fatty acids are essential for normal brain function, contributing to cell membrane structure, nerve growth, neurotransmitter regulation, and reducing inflammation. Learn more about omega-3s in our comprehensive overview article.
