A cross-sectional observational study analyzed 3,581 urban black and white young adults between the ages of 18 and 30 for hostility levels based upon their fatty acid intakes. Data obtained from hostility measurements in 1990-1991 and dietary assessments in 1992-1993, both from an ongoing cohort study, were used in this trial. Analysis of this data after adjustment for multiple variables revealed a significant inverse association between fatty fish intake and hostility. No association was observed between total omega-6 fatty acid intake or omega-6/omega-3 ratios and hostility. The researchers concluded that regular consumption of fish rich in omega-3 fatty acids, particularly DHA, is associated with reduced odds for hostility.
