Interactions between genes and environment, are likely to be crucial in the development of the common diseases such as type 2 diabetes. It was recently shown that FADS1 and FADS 2 genotypes are the strongest genes in a genome-wide analysis regulating serum fatty acid profile.The aim of this study is to test if subjects with the CC and TT genotypes of the FADS1 gene (rs174547) respond differentially to a diet supplemented with linoleic acid (substrate for FADS). We hypothesize that subjects with the TT genotype with more active desaturases will be more sensitive to dietary modification leading to more robust differences in serum FA profile, tissue inflammation and serum lipids.

Inclusion Criteria: Participant of Metabolic syndrome in men (METSIM) cohort BMI 20-30 kg/m2 Healthy CC/TT genotype (rs 174547) Exclusion Criteria: Type 2 diabetes Other chronic disease Inclusion Criteria: Participant of Metabolic syndrome in men (METSIM) cohort BMI 20-30 kg/m2 Healthy CC/TT genotype (rs 174547) Exclusion Criteria: Type 2 diabetes Other chronic disease Fatty Acid Lean and overweight subjects (BMI >20kg/m2 <29kg/m2 ) with CC and TT genotypes of FADS1 polymorphism (rs174547) were recruited from the METSIM study (METabolic Syndrome in Men, currently >10000 men included from the population living in Kuopio).
Interactions between genes and environment, are likely to be crucial in the development of the common diseases such as type 2 diabetes. Recently, the investigators have obtained data that genotypes of genes encoding for fatty acid desaturases 1 and 2 (FADS1 and FADS2) are the strongest genes in a genome-wide analysis regulating serum fatty acid profile.The aim of this study is to test if subjects with different genotypes of the FADS2 gene respond differently to a diet supplemented with linoleic acid or alpha-linolenic acid (substrates for FADS2). The study hypothesizes that subjects will be more sensitive to the dietary modifications according to their genotype leading to more robust differences in serum FA profile, tissue inflammation and serum lipids.
