If you injure your head take omega-3 fatty acids

I hope this never happens to you, but if you or someone you have responsibility for ever sustain a traumatic brain injury (TBI), even a mild one, omega-3 fatty acids are one important part of the solution. This study published in the Journal of Neurotrauma explains how brain injury reduces the activity of a factor important for maintaining brain health called Sir2α (silent information regulator 2 alpha). The authors describe multiple aspects of the protective effect of omega-3 fatty acids and conclude: "Our results suggest that TBI may compromise neuronal protective mechanisms by involving the action of Sir2α. In addition, results show the capacity of omega-3 fatty acids to counteract some of the effects of TBI by normalizing levels of molecular systems associated with energy homeostasis."
