Nov 10 2011 --- Researchers at Ohio State University Center for Clinical and Translational Science (CCTS) investigated whether EPA and DHA might play a role in reducing the level of cytokines in the body, compounds that promote inflammation, and perhaps even reduce depression. For the study, they recruited 68 first- and second-year medical student volunteers. Half received omega-3 supplements, while the other half were given placebos. The students were randomly divided into six groups, all of which were interviewed six times during the study. At each visit, blood samples were drawn from the students who also completed a battery of psychological surveys intended to gauge their levels of stress, anxiety or depression. The students also completed questionnaires about their diets during the previous weeks.
