Recent evidence indicates that genetic variation in fatty acid desaturases 1 and 2 (FADS1 and FADS2) is associated with changes in plasma fatty acid profiles; however, the association with altered desaturase activity has not been examined in different ethnic populations. The present study examined whether genetic variation in the FADS gene cluster regulates(More)
Circulating fatty acids (FA) are associated with a multitude of chronic diseases. However, a major gap in establishing such relationships is the lack of accepted fatty acid reference ranges representing healthy individuals. Data on validated FA reference ranges would provide a better understanding of study baseline measures and aid in the evaluation and(More)
BACKGROUND There is great interest in the relationship between polyunsaturated fatty acids and health. Yet, the combinatory effect of factors such as sex, ethnicity, genetic polymorphisms and hormonal contraceptives (HC) on the concentrations of these fatty acids is unknown. Therefore, we sought to determine the effects of FADS polymorphisms, and HC use in(More)
Inflammation is a recognized risk factor for the development of chronic diseases, such as type 2 diabetes and atherosclerosis. Evidence suggests that individual fatty acids (FA) may have distinct influences on inflammatory processes. The goal of this study was to conduct a cross-sectional analysis to examine the associations between circulating FA and(More)
INTRODUCTION Past research has reported that single nucleotide polymorphisms (SNPs) in fatty acid desaturase 1 and 2 (FADS1/2) can influence plasma fatty acid (FA) profiles. Changes in FA profiles are known to influence inflammatory processes; therefore both FA and SNPs in FADS1/2 may affect inflammation. The goals of this study were to (i) examine the(More)
Fatty acids (FA) represent a diverse class of molecules known to regulate inflammatory pathways. Therefore enzymes that regulate FA metabolism are attractive candidates to better understand the relationship between FA and inflammation. Stearoyl-CoA desaturase 1 (SCD1) is rate limiting for the conversion of saturated FA (SFA) to monounsaturated FA (MUFA).(More)
BACKGROUND The conjugated linoleic acid isomer cis9trans11 CLA can be endogenously synthesized from trans vaccenic acid (C18:1 t11) via desaturation at the delta 9 position catalyzed by the stearoyl-CoA desaturase 1 (SCD1), also known as delta-9 desaturase (D9D). Diet, hormonal regulation of gene expression and single nucleotide polymorphisms (SNPs) have(More)
BACKGROUND Choline deficiency during pregnancy can lead to adverse birth outcomes, including impaired neurodevelopment and birth defects. Genetic variants of choline and one-carbon metabolism may also influence birth outcomes by altering plasma choline concentrations. The effects of maternal ad libitum choline intake during pregnancy and fetal genetic(More)
Personal genetic information has become increasingly accessible to the public as a result of direct-to-consumer (DTC) genetic tests; however, concerns have been raised over their value and potential risks. We compared the effects of providing genotype-based dietary advice with general recommendations on behavioral outcomes using a randomized controlled(More)
BACKGROUND Proponents of consumer genetic tests claim that the information can positively impact health behaviors and aid in chronic disease prevention. However, the effects of disclosing genetic information on dietary intake behavior are not clear. METHODS A double-blinded, parallel group, 2:1 online randomized controlled trial was conducted to determine(More)
