ISLAMABAD, June 05 (Online): Scientists from the University of Pennsylvania have found that people who take omega-3, which is found in fish, flaxseed, and walnuts, are less likely to have aggressive and violent outbursts.<\/p>\n
Poor nutrition has been cited as a connection to aggressive and antisocial behavior, and combining cognitive behavioral therapy (CBT) with omega-3 in regular diets could be beneficial.<\/p>\n
Adding omega-3s to a daily dietary regime is fairly easy given the accessibility of supplements and grocery-store items like edamame, seaweed, flaxseeds, and anchovies.<\/p>\n
Omega-3 fatty acids, a beneficial nutrient found in foods like sardines, salmon, walnuts, and chia seeds, can reduce aggressive and violent behavior, according to a new paper published in the journal Aggression and Violent Behavior.<\/p>\n
The paper, authored by University of Penn professor Adrian Raine with Lia Brodrick of the Perelman School of Medicine, examined 3,918 participants from multiple studies, samples, and laboratories between 1996 to 2024.<\/p>\n
The meta-analysis found that omega-3 could reduce \u201creactive aggression,\u201d which is manifested by impulsive responses to provocation, and \u201cproactive aggression,\u201d which is predetermined or \u201cpredatory,\u201d as the study says.<\/p>\n
Dr. Raine, who is also the Richard Perry University Professor of Criminology, Psychiatry, and Psychology, has for years studied neurocriminology, aggressive behavior in adults and children, and antisocial behavior. This paper used 35 independent samples included in 29 studies from 19 independent laboratories. The results applied broadly across multiple populations, ages, and genders.<\/p>\n
\u201cResults of this study show that omega-3 supplementation significantly reduces aggressive behavior in the short-term, albeit at a modest level,\u201d the paper says. \u201cGiven the enormous economic and psychological cost of aggression and violence in society, even small effects sizes need to be taken seriously.\u201d<\/p>\n
\u201cOmega-3 supplementation has been argued to benefit a number of psychopathologies, including depression and anxiety, and more debatably schizophrenia-spectrum disorders. It certainly influences the serotonin system in a beneficial manner, but this is not unique as it influences other neurotransmitters too,\u201d Dr. Raine told Medical News Today.<\/p>\n
\u201cThe challenge we have is understanding exactly how omega-3 influences neurophysiology in a specific way to benefit mental health,\u201d he said.<\/p>\n
Do omega-3s affect mental health?
\nOmega-3s are generally known to have a number of physical health benefits. They help maintain cell structures, can prevent obesity and heart disease, and can reduce inflammation in the body. However, the body is not able to produce them itself, so external supplements or sources of nutrition are necessary to get them.<\/p>\n
There are three types of omega-3 fatty acid:<\/p>\n
alpha-linolenic acid (ALA), present in flaxseeds, chia seeds, and walnuts.
\neicosapentaenoic acid (EPA)
\ndocosahexaenoic acid (DHA)
\nDHA and EPA are mostly present in cold-water fatty fish, such as mackerel, salmon, herring, and sardines.<\/p>\n
Melanie Murphy Richter, a registered dietitian nutritionist and the director of communications for the nutrition company Prolon, who was not involved in the research, told Medical News Today that in addition to their physical benefits, omega-3s can interact with the brain in multiple ways.<\/p>\n
\u201cThe presence of omega-3s, most especially DHA, can make these vesicular membranes more receptive to the signals that prompt the release of serotonin. By improving this process, more serotonin is available to transmit between neurons in the brain and other parts of the central nervous system (CNS). Additionally, Omega-3s can impact the expression of certain genes by increasing the functionality of certain enzymes that create serotonin\u2019s precursor, 5-HTP. This can also enhance serotonin production,\u201d Richter said.<\/p>\n
\u201cOmega-3s can make a wonderful complement to the antidepressant effects of SSRIs by increasing the availability of serotonin within the membranes of the brain. Due to their anti-inflammatory capabilities, omega-3s can also reduce inflammation in the brain, which can help enhance SSRI function.\u201d

How do omega-3s regulate aggression?
\nRaine\u2019s paper points out that \u201cpoor nutritional status is a risk factor for externalizing behavior problems,\u201d which has prompted greater interest in looking at how nutritional supplements can reduce such behavior across a society.<\/p>\n
It cites several studies in explaining that omega-3 could be a bridge between nutritional deficiency and violent or aggressive behavior, stating that \u201ccorrelational research has also shown that fish consumption is negatively associated with cross-country homicide rates.\u201d<\/p>\n
Richter said that omega-3s can regulate serotonin and mood, which when coupled with other treatment avenues, can make a difference in antisocial or aggressive behavior.<\/p>\n
\u201cIf, for instance, a person\u2019s dysregulated moods and emotions are related to chronic inflammation as a result of poor diet or other toxic environmental factors, Omega-3 supplementation can have a decently big impact on helping to regulate emotional outbursts like road rage. In fact, one studyTrusted Source showed that a higher level of Omega-3 status was linked to lower aggressive behavior in adult prisoners. Because of the effects on inflammation, Omega-3 can play a big role in the reduction of irritability and anxiety. The presence of Omega-3 can increase the availability of serotonin release from membranes in the brain, helping to improve overall mood and relaxation,\u201d Richter said.<\/p>\n
OMEGA-3S AND CBT
\n\u201cOmega-3s can make a wonderful adjunct therapy to cognitive behavioral therapy (CBT). Many people have not learned how to acknowledge and work through certain emotions like anger or rage. CBT can teach practical tips on how to relax, problem-solve, and detach from certain external circumstances.\u201d
\n\u2014 Melanie Murphy Richter, RDN<\/p>\n
Raine echoed this sentiment, saying that the combination of therapy and nutritional supplementation is extremely promising.<\/p>\n
\u201cWe have done some studies comparing omega-3 with CBT and social skills training to reduce aggression, and in some cases, we find omega-3 performs better,\u201d Raine said. \u201cBut we have also found that the combination of omega-3 with CBT can be especially beneficial in reducing aggression. So, an approach in which omega-3 supplements other psychological interventions could be particularly promising.<\/p>\n","protected":false},"excerpt":{"rendered":"
