Background: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are associated with protection against components of the metabolic syndrome, but the role of a-linolenic acid (ALA), the metabolic precursor of EPA and DHA, has not been studied. The D-desaturase enzyme converts ALA into EPA and DHA, and genetic variation in the D-desaturase gene (FADS2) may affect this

BACKGROUND Experimental studies suggest that long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs) may reduce the risk of atrial fibrillation (AF). Prior studies evaluating fish or n-3 PUFA consumption from dietary questionnaires and incident AF have been conflicting. Circulating levels of n-3 PUFAs provide an objective measurement of exposure. METHODS AND RESULTS Among 3326 US men and women...

chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

Research indicates several possible human health benefits associated with consumption of flax (Conners, 2000). Flax contains approximately 20 percent alphalinolenic acid (ALA; DM basis), an essential omega-3 fatty acid that is a precursor for eicosapentaenoic acid (EPA), which in turn is a precursor for the formation of eicosanoids. Eicosanoids are hormone-like compounds that play an essential ...
