BACKGROUND: The influence of supplementing the diet with long-chain n-3 polyunsaturated fatty acids (PUFA) from fish oil on plasma lipids and lipid peroxides and the production of pro-inflammatory mediators in normolipidaemic and hypercholesterolaemic rats were studied. MATERIALS AND METHODS: Rats were divided into four groups and fed one of the ...

The worldwide increase in aquaculture production and the concurrent decrease of wild fish stocks has made the replacement of fish oil in aquafeeds an industry priority. Oil from a plant source Echium plantagineum L., Boraginaceae, has high levels of stearidonic acid (SDA, 18:4omega3, 14%) a biosynthetic precursor of omega-3 long-chain ...

Although several studies have reported a positive effect of n-3 essential fatty acids (EFAs) on bone density post-ovariectomy, the role of specific EFAs has yet to be fully elucidated. In this study, ovariectomised (OVX) rats were supplemented with 0.1 g (LOW) or 1.0 g (HIGH) of eicosapentaenoic acid (EPA)/kg body ...

BACKGROUND: Elevated fibrinogen, activated factor XII (FXIIa), and factor VII coagulant activity (FVIIc) are associated with higher risk of fatal ischemic heart disease. This study tested the hypothesis that lowering the dietary ratio of n-6 to n-3 polyunsaturated fatty acids (n-6:n-3) would modify these risk factors in older men and ...

Increased awareness of obesity has led to a dietary shift toward "heart-friendly" vegetable oils containing omega-6 polyunsaturated fatty acid (omega-6 PUFA). In addition to its beneficial effects, omega-6 PUFA also exhibits proinflammatory and prooxidative properties. We hypothesized that chronic dietary omega-6 PUFA can induce free radical generation, predisposing the cardiac ...

Supplementation with fish oils, rich in n-3 polyunsaturated fatty acids, modifies cardiovascular risk factors. However, dose-response relationships are poorly defined and whether similar effects are seen in young and older subjects is not known. This study determined the effect of supplementing the diet of young and older male subjects with ...

BACKGROUND: Blood levels of the anti-inflammatory and cardioprotective omega-3 eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids are determined primarily by dietary consumption. There is reason to believe that hemodialysis patients are at risk for inadequate omega-3 intake and, consequently, low blood levels. METHODS: This question was tested in 75 long-term ...

BACKGROUND: The worldwide diversity of dietary intakes of n-6 and n-3 fatty acids influences tissue compositions of n-3 long-chain fatty acids (LCFAs: eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids) and risks of cardiovascular and mental illnesses. OBJECTIVE: We aimed to estimate healthy dietary allowances for n-3 LCFAs that would meet the nutrient ...
