Background and objectives: Farm-raised tilapia contains very low levels of the beneficial very long-chain omega-3 fatty acid and very high levels of omega-6 fatty acid. Excessive amounts of omega-6 fatty acids and a very high omega-6/omega-3 ratio, promote the pathogenesis of many diseases, including cardiovascular disease, cancer, and inflammatory and autoimmune diseases, whereas increased levels of omega-3 PUFA (a low omega-6/omega-3 ratio) exert suppressive effects. Hence, the study determined the omega-3 and omega-6 fatty acid content of farmed tilapia and the omega-6/omega-3 ratio. Methods: Samples of farmed tilapia were taken from four sites namely: Batangas, Nueva Ecija, Pampanga and Isabela. The omega-3 and omega-6 fatty acid levels in farmed tilapia and the omega-6/ omega-3 ratio were analyzed using gas chromatography. Results: Tilapia from Isabela has the highest amount of f..
