Consuming omega-3 fatty acids might lower aggression levels.
For a while, Omega-3 fatty acids have been associated with numerous health benefits. They've been known to boost the immune system, safeguard blood vessels, and exhibit anti-inflammatory properties. Now, researchers from the University of Pennsylvania have found another advantage of these acids.
Recently, a review was conducted on 35 samples from 29 different studies, with a collective 3918 participants. Dating back to 1996 and ending in 2024, these data were analyzed by Neurocriminologist Adrian Raine and Research Coordinator Lia Brodrick. Participants ranged in age from childhood to 60 years old. The review revealed that regular consumption of Omega-3 supplements slightly but noticeably decreased aggression levels. Factors like age, gender, medical condition, Omega-3 duration, and dosage can contribute up to a 28% reduction in aggressive tendencies. "I believe it's time to include Omega-3 dietary supplements to tame aggression, regardless of whether it arises in the community, in a hospital setting, or in the penal system," said Raine in an article for Penn Today.
Analysts also discovered that Omega-3 supplements could reduce both reactive and proactive aggression in people. Reactive aggression refers to a reaction to provocation, while proactive aggression is a tendency to instigate conflict.
Not a magic bullet
Raine and Brodrick affirm that Omega-3 is not a miracle cure that will eliminate all cases of violence. However, they're convinced that it could contribute to reducing aggression levels, even if just a little. "Omega-3 isn't a one-size-fits-all solution that will entirely eliminate the problem of violence in society. But could it help? With these findings, we're optimistic that it can, and we should start putting this knowledge into practice. Parents with aggressive children, for instance, should know that in addition to every other treatment their child is receiving, a weekly extra-fish portion could make a difference."
The authors cautiously acknowledge that their results apply only to short-term effects and more research with a larger pool of participants and extended timeframes is needed. Nonetheless, their work offers insight into the impact of Omega-3 supplements on brain health and function.

In light of these findings, incorporating Omega-3-rich foods into children's diets or providing them with supplements could potentially minimize aggressive behaviors. Furthermore, understanding the role of Omega-3 in reducing aggression levels might inspire future research in the field of psychology, particularly in relation to nutrition and education.
