Primary Outcome Measures
Serum ln(TNF-a)
log-transformed serum Tumor Necrosis Factor-alpha (TNF-alpha)
Serum ln(IL-6)
log-transformed serum Interleukin-6 (IL-6)
ln(CES-D)
log-transformed Center for Epidemiologic Studies Depression Scale (CES-D) score The CES-D is a self-report scale designed to measure current symptoms of depression rated on a four-point likert scale.
Scores range from 0-60, with higher scores indicating a higher frequency of depressive symptoms.

5. Study Description
Brief Summary
This study is designed to examine the effects of fish oil on immune function and mood.
Detailed Description
The beneficial effects of fish oil (or eating fish more frequently) include reductions in triglycerides, blood pressure, and heart rate, as well as increases in HDL cholesterol, the "good" type of cholesterol. In addition, certain aspects of immune function also appear to show favorable responses to fish oil supplementation, and some studies suggest that fish oil helps to improve mood and decrease depression.
This study is designed to examine how supplementation with omega-3 polyunsaturated fatty acids (key fish oil components) affects aspects of your immune response, and your mood; because some research suggests that people who eat more fish may do better during stressful times, the study will also examine how fish oil affects your immune response to stress, certain stress hormone responses, and your psychological response to stress.
