A diet rich in omega-3s could reduce the severity of brain damage after a stroke.  Researchers from Universite Laval in Quebec, Canada, observed that mice that had been fed a diet rich in DHA, an omega-3 fatty acid, for three months had 25% less brain damage following stroke than mice that had eaten a control diet.  The full study was published in Stroke (doi:10.1161/STROKEAHA.111.620856).
