Dietary Fatty Acids and the Metabolic Syndrome: A Personalized Nutrition Approach. 
Dietary fatty acids are present in a wide variety of foods and appear in different forms and lengths.  The different fatty acids are known to have various effects on metabolic health.  The metabolic syndrome (MetS) is a constellation of risk factors of chronic diseases.  The etiology of the MetS is represented by a complex interplay of genetic and environmental factors.  Dietary fatty acids can be important contributors of the evolution or in prevention of the MetS; however, great interindividual variability exists in the response to fatty acids.  The identification of genetic variants interacting with fatty acids might explain this heterogeneity in metabolic responses.  This chapter reviews the mechanisms underlying the interactions between the different components of the MetS, dietary fatty acids and genes.  Challenges surrounding the implementation of personalized nutrition are also covered.
