Omega-3 for aggressive behaviour


Today, we share a curious new: Prisoners with lower omega-3 index (EPA + DHA level in red blood cells) are more aggressive and have higher scores in attention deficit disorder scales.

Lately, it has been observed that omega-3 supplementation contributes to a decrease in aggressive behaviour in prison populations. In order to evaluate this observation, a group of Australian researchers have conducted a study with 136 adult male prisoners: their omega-3 index ranged from 2.3% to 10.3% (an index equal or greater than 8% is considered a good one); so, some inmates already had a good omega-3 intake, however the median was 4.7%, a lower overall omega-3 intake than the general Australian population. The next step was to determine if the value of the omega-3 index correlated with attention deficit and aggressive behavior. To evaluate it, their scores in several scales of aggression and attention deficit disorder were taken into account. Outcomes showed negative correlations between omega-3 index and aggression scores (anger, hostility, and indirect aggression), and between the index and some measures of attention deficit disorder (attention, effort and memory, among others).

Again, omega-3 show to be not only very important but essential. Don’t they?
