Fish and omega 3 fatty acid intake has been an area of interest for the potential protection effect against cardiovascular disease. Metabolic syndrome is one risk factor for Coronary Heart Disease (CHD) and has also been associated with increased CHD mortality and morbidity. Because fish/omega 3 intake may protect from CHD, this study had the objective of determining the effect of intake on metabolic disease prevalence. This study used 3,504 male and female Koreans aged 40-69 from a previous study. Each participant completed a food frequency questionnaire to identify omega 3 intake. Metabolic syndrome incidence was identified by health examinations during a follow up period. The data revealed that fish intake was significantly associated with more acceptable triglyceride and HDL levels. Daily fish intake in males (but not females) also demonstrated a significant decrease in occurrence in metabolic syndrome. The study concludes with the thoughts that a diet high in omega 3 fatty acids and fish was significantly associated with a decrease risk of metabolic syndrome in men, but not women. Further research is needed to determine if fish intake should be encouraged for the purpose of metabolic syndrome prevention.
This study demonstrates the association between specific nutrients and prevention of chronic disease. It is important for dietitians to maintain up to date on nutrition research to assist in prevention of chronic illness through specific MNT and enhance the profession of dietetics.
