Omega-3 Fatty Acid Ingestion as a TBI Prophylactic

Given the hazardous nature of combat operations and training exercises (e.g. airborne operations) conducted by the United States military, servicemembers are at high risk for sustaining a traumatic brain injury (TBI). Since the beginning of the Iraq and Afghanistan wars, almost a quarter of a million servicemembers have sustained a TBI.1 A large number of TBIs are a result of the concussive forces generated by improvised explosive devices (IED). A smaller number are a result of penetrating head wounds. Others may be caused by activities resulting in powerful acceleration, deceleration, or rotational forces. Therapies for treating TBI thus far have been limited. Much of the research conducted to date has focused on post-injury pharmacological interventions.2 Additionally, better protective equipment could help in preventing TBIs; however, these issues are outside the scope of this paper. A relatively new area of research is investigating prophylactic measures taken to lessen the effects of TBI. One such measure involves nutritional interventions and their effects on TBI severity. Therefore, the purpose of this paper is to elucidate the potential benefits of omega-3 fatty acid intake as it relates to TBI severity.
