Research Abstract

Firstly, we examined cardiovascular behavior of young fish-eaters at rest, during acute mental stress, and during recovery. Secondly, we examined the effect of omega-3 fatty acids, otherwise known as fish oil, on cardiovascular responses at rest, during acute mental stress, and during recovery. As a result, both fish-eaters and individuals who have undergone dietary supplementation of omega-3 fatty acids showed healthy hemodynamics such as decreased blood pressure. These results might suggest a potential underlying mechanism by which omega-3 fatty acids and/or frequent fish consumption promote cardiovascular health.
