Men with MetS in the present study were characterized by an elevated apoA-I FCR after the control diet (0.32 pool/day), and these figures are comparable with those from a previous kinetic study in which dyslipidemic subjects with MetS also had higher apoA-I FCR compared with controls (0.30 vs. 0.20 pool/day) [28]. This evidence concerns the gene APOA1 and metabolic syndrome.
